Ten rats/sex/group were observed periodically for behavior (functional observational battery) and motor activity.Sacrifice and pathology After 91 days of treatment, tissues of 10 animals/sex/group were fixed in situ, and brains were removed. These animals received complete necropsies, and tissues from 6 animals/sex/group were processed for evaluation of the nervous system by light microscopy. The 5 animals/sex/group not sacrificed and perfused in situ were killed by severing the brachial vessels to permitexsanguination. These animals received complete necropsies, and the liver, kidneys, brain, lungs, adrenals, and testes (males) were weighed. Liver and testes were examined by light microscopy. Statistics Data for continuous variables were analyzed with Levene's test for homogeneity of variance, analysis of variance (ANOVA), and by pooled variance t-tests. If Levene's test indicated heterogeneous variances, groups were analyzed with an ANOVA for unequal variances, followed by separate variance t-tests. Fisher's exact 2 x 2 groups comparisonswere used to analyze functional observational battery data. Motor activity counts were log transformed prior to analysis. Motor activity dose-effects, dose-sex interactions, and time-dose interactions were determined using repeated measures ANOVAs with dose and sex as grouping factors and time as a within-subject factor. Comparisons between treated and control groups were made for total test session activity (the sum of the counts across the 90-min test session) using ANOVA. To reduce the increased false positives associated with repeated significance testing, the correction p rocedure described by Mantel (Biometrics 36:381-399, 1980) was used when testing for overall significance. The frequency data for anatomic pathology were analyzed as described by Sokal and Rohlf (Biometry, WHFreeman, 1981). Any other information on materials and methods incl. tables

One female in the high dose treatment group (approximately 4000 mg/kg/day) died on Day 37. Males and females treated with the highest dose consumed less food and had lower body weights and body weight gains than control animals. Water consumption decreased in high-dose females (by an average of 17%).
Treatment with triethylene glycol monomethyl ether did not result in any clinical signs of toxicity, alterations in the functional observational battery, or gross microscopic lesions in the nervous system. Significant, small decreases in total test session motor activity were observed in the high-dose treatment group at the Day 60 (males only) and Day 90 (females) evaluation p eriods. Study personnel stated that “the decreases in motor activity were not considered to be neurotoxicologically significant based on the small magnitude of the changes, the parallel changes in body weights at the evaluation periods, and the lack of corroborative behavioraleffects from the functional observational battery evaluations or histological changes in central or peripheral nervous system tissues.”
Increased relative liver weight was observed in males treated with 4000 mg/kg/day (5.229 ± 0.3984) and 1200 mg/kg/day (3.951 ± 0.4191) versus control (3.214 ± 0.1519). Absolute liver weights of males treated with 4000 mg/kg/day were significantly greater than controls (25.926 ± 3.1591 versus 18.978 ± 1.4925). Microscopic changes (hepatocellular cytoplasmic vacuolization and/or hypertrophy) were noted in livers of high-dose males (14/15). The severity of these liver lesions was minimal or mild (with the exception of moderate or marked vacuolization for 4 high dose males). Mild cholangiofibrosis was observed around a small number of bile ducts in high-dose males (7/15). This was not considered by study personnel to be physiologically significant due to the limited number of bile ducts affected and the mild nature of the effect (Gill et al., Int J Toxicol. 17:1-22, 1998). Minimal or mild hepatocellular hypertrophy was seen in 10/15 high dose females. Three males treated with 400 mg/kg/day and 4 treated with 1200 mg/kg/day also exhibited minimal-mild hepatocellular cytoplasmic vacuolization and/or cellular hypertrophy (not statistically different from the controls). One control male had mild hepatocellular cytoplasmic vacuolization. N one of the females treated with 400 or 1200 mg/kg/day exhibited these changes. Hepatocellular hypertrophy was considered by study personnel to be a possible adaptive change to accommodate increased demand to metabolize the test substance.
The testes of males in the high dose group exhibited degeneration (12/15) and/or atrophy (5/5) of the seminiferous tubules (spermatocytes or developing spermatids). These effects were concluded to be related to treatment. The severity of the lesions was primarily mild to moderate for degeneration (11/12) and minimal to moderate for atrophy (5/5), indicating that not all tubules were affected and that a limited number of cells was affected within the affected tubules. One male treated with 1200 mg/kg had severe seminiferous tubule atrophy, a complete loss of cell types in the tubules (except for Sertoli cells) and moderate Leydig cell hypertrophy (not significant from control). This was not considered to be related to treatment because of the lack of a plausible explanation for the unusual dose-response relationship (the effect at this dose was more severe than that of a higher dose) and the low incidence of animals affected at this dose level (Gill et al., Int J Toxicol 17:1-22, 1998). N o testicular changes were noted in males treated with 400 mg/kg/day TGME. Remarks on results including tables and figures

Overall remarks, attachments Overall remarks

The route of administration and maximum dose level was specified in a testing consent order (EPA. 1989. 40 CFR 799, Fed Reg 54:13470-13477). The highest dose level was initially set at 5000 mg/kg/day, but was decreased to 4000 mg/kg/day based on results of a 14-day dose range-finding drinking water study that demonstrated signs of debilitationat levels greater than 4000 mg/kg/day (Gill and Hurley, 1990).The authors state that a possible contributing factor in the development of testicular lesions at the high dose was low-level contamination of the test substance with the known testicular toxicant 2-methoxyethanol (EGME). EGME was present in the test substance at a concentration of 0.02  0.04 %, resulting in a EGME dose up to 1.7 mg/kg/day for animals in the high dose group. Given the length of the study, it is possible that EGME contributed to the testicular lesions. A comparison between the doses of EGME and TGME required to produce testicular toxicity indicated that TGME is 350 times less potent than EGME in producing testicular lesions in the rat. The dose of TGME that caused testicular toxicity (4200 mg/kg/day) is 4 times greater than the 1000 mg/kg/day limit dose generally recommended for subchronic studies.

Based on the results of the study, the summary preparer assigned a NOAEL for effects on the liver of 400 mg/kg/day, and a LOAEL of 1200 mg/kg/day (based on increased relative liver weight of males at this dose). The summary preparer-assigned NOAEL and LOAEL for testicular effects are 1200 and 4000 mg/kg/day, respectively. The EPA has determined the NOAEL for testicular effects is between 400 and 1200 mg/kg/day (Anderson, L. Triethylene glycol monomethyl, monoethyl and monobutyl ethers RM1 screening document (draft), Feb. 24, 1995).

Organ weight (standard set), gross pathology and histopathology (control and high dose group) were evaluated upon necropsy. The oocytes, corpora lutea, and follicles from each ovary were evaluated with regard to their normal development. Bone marrow smears were prepared from each animal from the shaft of the femur.The testes and epididymes also were examined microscopically for males in the intermediateand low-dose groups. Examinations Observations and examinations performed and frequency Parameters evaluated throughout the study included clinical and ophthalmic observations, dermal irritation, body weight, food consumption, clinical pathology, estrous cyclicity (daily vaginal smears during study weeks 12 and 13), hematology ( j ust prior to sacrifice), clinical chemistry ( j ust prior to sacrifice), and urinalysis ( j ust prior to dosing and during final week of dosing). Sacrifice and pathology Organ weight (standard set), gross pathology and histopathology (control and high dose group) were evaluated upon necropsy. The oocytes, corpora lutea, and follicles from each ovary were evaluated with regard to their normal development. Bone marrow smears were prepared from each animal from the shaft of the femur. The testes and epididymes also were examined microscopically for males in the intermediate- and low-dose groups. Other examinations Additional satellite groups of 5 rats/sex/dose level were administered TGME for 30 days for interim hematological (48 hr and 30 days), clinical chemistry (48 hr and 30 days), body weight determinations, clinical observations, and dermal irritation. Statistics For the main study group, the data for continuous variables were evaluated by Bartlett's test for equality of variances. Depending on the outcome of the test, data were analyzed using a p arametric or nonparametric analysis of variance (ANOVA), followed by a Dunnett's test ( p arametric data) or Wilcoxon rank-sum test (nonparametric data) with a Bonferroni correction for multiple comparisons when appropriate. Statistical outliers were identified by a sequential test, but were not excluded from analyses.
For the satellite group, all data (except those for differential leukocyte count and red blood cell p arameters) were first tested for equality of variance using Bartlett’s test. Hematologic and clinical chemistry parameters were evaluated during a two-way analysis of variance with the factors of sex and dose. Examinations were first made for a significant sex-dose interaction. Ifthis existed, a one-way ANOVA was preformed separately for each sex. If no sex-dose interaction was identified and a dose effect was identified, or if in the subsequent ANOVA separated by sex a dose-effect was identified, then separate ANOVAs were used for each treatment group with the control. A Bonferroni correction was used to control for multiple comparisons. Any other information on materials and methods incl. tables

The route of administration and maximum dose level was specified in a testing consent order (EPA. 1989. 40 CFR 799, Fed Reg 54:13470-13477). The highest dose level (4000 mg/kg/day) represented the maximum amount of test substance that could be retained on the back and sides of the rat as determined in a preliminary 2-week study (Yano et al. 1987. Dow Chemical Company Study ID: K-005610-001, Dated Nov. 25, 1987). The EPA has determined that based on severe testicular toxicity in 1/10 rats given 4000 mg/kg/day and minimal decreases in developing germ cells (1-5% of seminiferous tubules affected) in 1/10 rats given 1,200 mg/kg/day, the NOAEL for systemic toxicity is between 400 and 1200 mg/kg/day (Anderson, L. Triethylene glycol monomethyl, monoethyl and monobutyl ethers RM1 screening document (draft), Feb. 24, 1995). This value was reached even though it was recognized that the testicular changes in the 1,200 mg/kg/day rat were within historical control limits for Sprague-Dawley rats (0-17%).

There were no treatment-related hematological changes in the interim groups or in males administered test material for 13 weeks. A significant decrease (15%) in platelet counts was noted in females dosed with 4000 mg/kg for 13 weeks when compared to control (1217 +/- 280 x 103/cu mm); however, the value (1034 +/- 92 x 103/cu mm) was only slightly below the historical control range (1050 to 1262 +/- 93 to 294 x 103/cu m) Therefore, it was not considered to be toxicologically significant (Gill et al., Int J Toxicol 17:1-22, 1998). There were no other changes in any hematological parameters (hematocrit, hemoglobin, erythrocyte count, total leukocyte count, and red blood cell indices). There were no changes in clinical chemistries, urinalyses, organ weights, or estrous cyclicity measurements.
Bilaterally decreased spermatogenesis in seminiferous tubules and decreased spermatozoa in the epididymes (both were graded as severe) were noted in the testes of one high dose male rat. This animal had a complete lack of mature spermatids in greater than 41% of tubules in each testicle, few spermatids beyond stage 12 of development in the seminiferous epithelium, and decreased spermatic elements in the head and tail of greater than 41% of the tubules and ducts in the epididymides. The testes of one male treated with 1200 mg/kg exhibited different testicular changes [bilateral multifocal degeneration of spermatocytes and spermatids from germinal epithelium (graded as very slight), and multinucleated spermatids]. In this rat, all stages of the cycle of the seminiferous epithelium were observed in morphologically normal tubules. The epididymides of this rat had decreased spermatic elements in the head and tail of 1-5% of ducts. Some of the ducts also contained immature spermatids. Remarks on results including tables and figures

Study personnel concluded that the bilateral microscopic testicular changes observed in one high-dose and one mid-dose male rat were unrelated to treatment. Reasons given were that the dissimilarity of the lesions for the two animals suggested that they occurred spontaneously, and the incidence of animals with lesions (1/10 in each group) was well within that of historical controls (0-17%). Study personnel also stated that the degenerative changes in the testes of one mid-dose and one high-dose rat were not consistent with the types of lesions that have been attributed to 2-methoxyethanol (2-ME). The cell types that are most vulnerable to 2-ME are the pachytene spermatocytes and round spermatids (Chapin et al., Fund Appl. Toxicol 5:182-189, 1985). As the dose of 2-ME is increased, the number and types of cells affected increase up to the point that the germinal epithelium is significantly degenerated and all stagesof spermatogenesis are affected (Chapin et al., Fund Appl. Toxicol 5:182-189, 1985; Miller et al., Fund Appl Toxicol 3:49-54, 1983.). In contrast, the testicular effects seen with the high dose animal treated with TGME consisted of a virtually complete lack of mature spermatids beyond stage 12. All other stages, including spermatogonia and spermatocytes, were present and appeared morphologically normal. In the mid-dose rat, the only effects noted consisted of very slight degeneration of spermatocytes and spermatids similar to those seen in historical control animals.

Study personnel also stated that the lymphoid tissues and hematologic parameters, which have been reported to be affected at doses of 2-methoxyethanol that have been associated with testicular changes (Miller et al., Fund. Appl. Toxicol. 3:49-54, 1983) were unattected in this TGME study. Taking all factors into considereation, the testicular lesions observed in this dermal study could not be directly attributed to TGME exposure.

A few males and females treated with either 1000 or 2500 mg/kg/day had a few small scabs or crusts at the test site. These alterations were slight in degree and did not adversely affect the rats.
A number of clinical chemistry, hematological and urinalysis variables were significantly different from control. The lower albumin concentration in females from the 1000 mg/kg/day group and higher urea nitrogen concentration in males from the 2500 mg/kg/day group were not considered by study personnel to be related to treatment because the effects were not noted at higher concentrations. The lower albumin concentration in males treated with 4000 mg/kg/day also was not attributed to treatment by study personnel because the value was within the range of individual animal values in the control group. A slightly higher alanine aminotransferase activity was also statistically identified in rats from the 4000 mg/kg/day group. As the value was only marginally different from control and was not associated with any histologic changes in the liver, study personnel did not consider this to be related to treatment. A slightly higher red blood cell count and hemoglobin concentration was observed in rats given 4000 mg/kg/day. Since these were only slightly higher than control values, study personnel did not consider them to be related to treatment. A few of therats given 2500 or 4000 mg/kg/day had watery cecal contents and/or hemolyzed blood in the stomach. These gross pathologic observations were not associated with any histologic abnormalities in these tissues or alterations in hematologic and clinical chemistry parameters. Therefore, they were not attributed by study personnel to be related to treatment. Repeated dose toxicity: dermal UC MPEG 1985.002 UUID IUC5-53589035-b3c8-4a64-806b-44cbfd597674 Dossier UUID 0

Standard hematology and clinical chemistry parameters were evaluated for all animals just prior to sacrifice. Sacrifice and pathology N ecropsy: All animals were sacrificed and necropsied after 13 weeks of treatment. Weights were recorded for liver, kidneys, brain and adrenals of all animals and testes of males. Histopathologic examinations were performed on tissues from high-dose and control animals. Statistics Statistical Analyses: Body weight, food consumption, organ weight and clinical pathology data from the three groups were compared using Levene's test for homogeneity of variance. An analysis of variance was performed on the groups when data were homogeneous. If significantdifferences were found, group differences were delineated by grouped variance Student t-tests. When data were heterogeneous, Welch and Brown-Forsyth analyses were p erformed and significant differences among groups were determined using separate variance Student t-tests. Draize skin irritation scores were analyzed using the Kruskal-Wallis test, and significant differences in groups were determined using the Wilcoxon rank sum test (as modified by Mann-Whitney). Frequency data (i.e. histological) were compared using Fisher's exact tests. The p value of 0.05 (two-tailed) was used as the critical level of significance for all analyses.

A preliminary range-finding study in 15 rabbits dosed 6 hr /day for 9 days (Carpenter, Range finding tests on methoxy polyethylene glycols of approximate molecular weights 350, 550 and 750. Melon Institute of Industrial Research, University of Pittsburgh. Report dated 5-13-47.1947) showed that daily administration of 1 ml of 50% or 100% test material only caused mild skin irritation. Therefore, these doses were chosen for the 90-day study.

Absolute weights of the thymus and testes of rats treated with 1.25 g/kg/day were 83% and 93%, respectively of control weights (significantly different). Relative weights of these organs were not significantly different from control. There were no pathological abnormalities in either of these organs. Remarks on results including tables and figures

One, 3, and 2 animals in the low-, mid- and high-dose groups slipped their collars and therefore may have ingested the material during grooming. Results in these animals were not significantly different from those animals that did not slip their collars. Therefore, possible ingestion of material in these animals did not appear to affect the results of the study.

The investigators did not identify a NOAEL for the study. However, they stated that there were no indications of systemic toxicity secondary to repeated cutaneous exposure to MPEG-350 in this study. Based on the information given, the summary preparer assigned a NOAEL of 1250 mg/kg/day. This value is based on significant effects on body weight or weight gain at higher doses (although the authors stated that these effects may have been due to use of Elizabethan collars). Although the absolute weights of the thymus and testes of rats treated with 1.25 g/kg/day were significantly less than control, relative weights of these organs were not different from control, there were no histological changes in these organs, and these effects were not noted at higher doses. Therefore, they were considered by the summary preparer to be unrelated to treatment.

A preliminary range-finding study in 15 rabbits dosed 6 hr /day for 9 days (Carpenter, Range finding tests on methoxy polyethylene glycols of approximate molecular weights 350, 550 and 750. Melon Institute of Industrial Research, University of Pittsburgh. Report dated 5-13-47.1947) showed that daily administration of 1 ml of 50% or 100% test material only caused mild skin irritation. Therefore, these doses were chosen for the 90-day study.

Identity Carbowax MPEG-350 ( Details on test material Test material was Carbowax MPEG-350 (CAS No. 9004-74-4) from Union Carbide. This material is a mixture of several methylated glycol ethers of differing molecular weight (ranging from diethylene glycol monomethyl ether (C2) to heptadecaethylene glycol monomethyl ether (C17)). The majority of the material is in the C5-C11 range (87.445%). It contains 4.347 % (by weight) tetraethylene glycol monomethyl ether (CAS No. 23783-42-8), 1.303% triethylene glycol monomethyl ether (CAS No. 112-35-6), 0.181% diethylene glycol monomethyl ether (CAS No. 111-77-3).

Body weights of animals given 5.0 g/kg/day and body weight gains of animals given 2.5 g/kg/day were depressed. Absolute weights of the thymus and testes of rats treated with 1.25 g/kg/day were 83% and 93%, respectively of control weights (significantly different). Relative weights of these organs were not significantly different from control. There were no pathological abnormalities in either of these organs. Remarks on results including tables and figures

One, 3, and 2 animals in the low-, mid- and high-dose groups slipped their collars and therefore may have ingested the material during grooming. Results in these animals were not significantly different from those animals that did not slip their collars. Therefore, possible ingestion of material in these animals did not appear to affect the results of the study.

The investigators did not identify a NOAEL for the study. However, they stated that there were no indications of systemic toxicity secondary to repeated cutaneous exposure to MPEG-350 in this study. Based on the information given, the summary preparer assigned a NOAEL of 1250 mg/kg/day. This value is based on significant effects on body weight or weight gain at higher doses (although the authors stated that these effects may have been due to use of Elizabethan collars). Although the absolute weights of the thymus and testes of rats treated with 1.25 g/kg/day were significantly less than control, relative weights of these organs were not different from control, there were no histological changes in these organs, and these effects were not noted at higher doses. Therefore, they were considered by the summary preparer to be unrelated to treatment.

Remarks Details on test system and conditions Test Concentrations: The test material was dissolved in distilled water at stock concentrations of 50, 16.67, 5, 1.667, and 0.5 mg/ml. Concentrations were verified by HPLC to be: 51.4, 18.3, 4.91, 1.75 and 0.523 mg/ml. All positive control solutions (1 mg/ml 2-nitrofluorene, 100 micrograms/ml ICR-191, 30 micrograms/ml 2-anthramine) were prepared in DMSO (with the exception of 250 micrograms/ml sodium azide dissolved in water).
Test: Bacteria (0.1 ml of 10E8 or 10E9 S. typhimurium TA 98, TA100, TA1535, or TA1537), test chemical (0.1 ml of test solution, p ositive control, or solvent) and either buffer or S-9 mix (0.5 ml) were pre-incubated in sterile 12 x 75 mm tightly-capped culture tubes in a gyratory incubator (300rpm) at 30 degrees C for 30 minutes. Supplemented top agar (2 ml) was then added, the overlay was poured onto plates, and plates were incubated at 37 degrees C for 2 days. All dose levels (including positive and negative controls) were assayed in triplicate.
Revertant colonies were counted manually or with an automatic colony counter. The counter was calibrated periodically. A correction factor was used to compensate for the area not scanned by the counter (i.e. dish edge) and overlapping colonies. Evaluation criteria Evaluation Criteria: The test material was considered a mutagen if both the mean number of revertant colonies was at least 3 times higher than the mean of the negative (solvent) control and it induced a reproducible dose-response relationship over several concentrations. If the dose-response was not definitive, it was considered to be a presumptive mutagen. If the reversion rates were between 2 and 3 times that of negative controls, the results were considered equivocal or inconclusive.

Periodic examinations revealed no mycoplasma contamination. Cells were grown as a monolayer in Ham's F-12 nutrient mix supplemented with 5% heat-inactivated, dialyzed fetal bovine serum, 25 mM HEPES, 0.25 micrograms/ml Fungizone, 100 units/ml penicillin G and 0.1 mg/ml streptomycin sulfate. The selection medium used for the detection of mutants was Ham's F-12 nutrient mix without hypoxanthine, and supplemented with 10 micromolar 6-thioguanine, 5% serum, 25 mM HEPES, 2 mM L-glutamine and the antibiotics mentioned above.

Test materials: Test material was dissolved in water and further diluted (1:100) in culture medium. The concentrations of test material in stock solutions (200, 300, 400, 500 mg/ml)were verified by analytical methods.20-methylchlolanthrene (20-MC) was initially dissolved in DMSO, and further diluted in culture medium. Ethyl methanesulfonate (EMS) was dissolved in culture medium.
Preliminary test : The cytotoxicity of the test material was assessed by determining the ability of the treated cells to form colonies. The cultures (3 p er dose level) were treated with test material in the absence or presence of S-9, incubated for up to 7 days, fixed with methanol and stained with crystal violet. The number of colonies/dish was counted and the mean colonies/dish/treatment were expressed relative to the negative control value. The test material was not cytotoxic at up to 5000 micrograms/ml. Based on this result, this was the highest concentration used for the genemutation assay.
Mutation test: Cells in logarithmic growth phase were trypsinized and plated in medium containing 5% serum at a standard density (200 cells/100 mm dish for toxicity assay and 1 x 10E6 cells/100 mm dish for gene mutation assay) p rior to treatment. Approximately 24 hours after plating,the medium was replaced with Ham's medium without serum, S-9 mix prepared from liver homogenate of Aroclor-1254 treated (500 mg/kg) male, Sprague Dawley rats (when applicable) and test material (2000 to 5000 micrograms/ml), p ositive control (either 621 micrograms/ml EMS or 4 micrograms/ml 20-MC) or water. The total volume of the treatment medium was 10 ml/100 mm dish. The number of dishes treated at each dose level was based on the expected degree of toxicity that would yield at least 1 x 10E6 surviving cells. Cells were treated for 4 hours at 37 degrees C. Exposure was terminated by washing the cells with p hosphate-buffered saline. Cells were trypsinized 18-24 hours after termination of the treatment and replated at a density of 1 x 10E6 cells/100 mm dish. This step was repeated on the third and sixth days following treatment. On Day 8, cultures were trypsinized and plated at a density of 2 x 10E5 cells/100 mm dish (5 dishes per treatment) in selection medium for the determination of HGPRT-mutants and 200 cells/60 mm dish (5 dishes/treatment) in Ham's medium without hypoxanthine for determination of cloning efficiency. Dishes were incubated for 7-9 days, fixed with methanol and stained with crystal violet. The mutation frequency per 10E6 clonable cells was calculated as the total number of mutant colonies/cloning efficiency(number of colonies per number of cells plated). Evaluation criteriaThe assay was considered valid, if the positive control chemicals induced significant increased in mutation frequencies in assays with and without S-9 (EMS: 142.0-153.6; 20-MCA: 64.7-86.3). Statistics Statistical analysis: The frequencies of mutants per 10E6 clonable cells were statistically evaluated by pairwise tests (treatment vs. negative control) and by linear and quadratic trend analysis over the dose range. Results and discussions Test results Species/strain Chinese hamster Ovary (CHO) Metabolic activation with and without Test system all strains/cell types tested Genotoxicity negative Cytotoxicity yes Vehicle controls valid yes N egative controls valid yes

Positive controls valid yes Additional information on results The mutation frequencies observed in cultures treated with the test chemical in the absence (1.4 to 7.1) and presence of S-9 (0 to 7.1) were not significantly different from the concurrent negative control values (1.4 to 9.6) and were within the laboratory historical negative control range.
Cytotoxic concentration: > 5000 micrograms
The assay was valid, since the positive control chemicals induced significant increased in mutation frequencies in assays with and without S-9 (EMS: 142.0-153.6; 20-MCA: 64.7-86.3).

Remarks Details on test system and conditions Cells (2 x 10E5) were incubated with medium containing the test compound or relevant controls [untreated control, solvent control and positive controls methyl methanesulphonate (20 micrograms/ml without S-9) and benzo(a) p yrene (25 micrograms/ml with S-9)] for either 3 hours in the presence of S9 mix (from Aroclor 1254-induced rat liver) or 24 hours in the absence of S9 mix. The concentrations of test material used (from 10 to 5000 micrograms/ml without S-9 and 100 to 5000 micrograms/ml with S-9) were chosen based on the results of p reliminary miscibility and mitotic index studies. Duplicate cultures were prepared for each test condition. Two separate experiments were conducted using different concentrations. Metaphase cells were prepared on glass microscope slides for the analysis of chromosome aberrations 24 hours following exposure for the cultures with or without S9 mix. All slides were coded. Where p ossible, 200 metaphases were scored for each dose group. Only those cells showing the modal chromosome number (20) +/- 2 were analyzed for chromosome damage. Chromosomeaberrations were classified according to the scheme described by Savage (J Med Genetics 12:103-122, 1976). Evaluation criteria N ot specified. Statistics The mitotic index of each group was assessed by counting the number of metaphases in a total of 1000 cells. Data were assessed for heterogeneity using the Fisher’s exact test. The number of aberrations excluding gaps, aberrations including gaps, isogaps and/or chromatid gaps and p olyploidy and/or endoreduplication of treated cells was compared to controls using the Fisher’s exact test. A Cochran-Armitage trend test was carried out on the dose/response. The test was p erformed twice, once excluding control data and the other including the solvent control. Results and discussions Test results Species/strain Chinese hamster Ovary (CHO) Metabolic activation with and without Test system all strains/cell types tested Genotoxicity negative Cytotoxicity no, but tested up to limit concentrations Vehicle controls valid N egative controls valid

Positive controls valid Additional information on results Cells exposed to test material at concentrations up to 5000 micrograms/ml showed no increase in chromosome damage or no linear trend compared to negative controls in either experiment. The positive control induced significantly more cells with aberrations compared to the negative controls (for untreated control and for solvent control). In the first experiment with S-9 (up to 1875 micrograms/ml test material), there was no effect of treatment on the incidence of type of aberration observed. However, there was a significant difference in the number of cells with chromatid gaps and/or isogaps between the untreated control (7/200) and solvent control cultures (1/200). In the second experiment with S-9 (cells were treated with 1500, 3000 or 5000 micrograms/ml test material), there was a significant difference in the number of cells with aberrations including gaps (11/200) and cells with chromatid gaps and/or isogaps (8/200) at the 1500 micrograms/ml compared to the solvent control (2/199 and 0/199, respectively). There also was a significant increase in the number of cells with chromatid gaps and/or isogaps at the high concentration (5/200) compared to control, and between both controls (untreated control had 7/200). N o linear trend was observed either by including or excluding the solvent control from the analysis. The positive control caused increases in aberrations with and without gaps compared to the solvent control in both studies.
The cytotoxic concentration was > 5000 micrograms/ml. Remarks on results including tables and figures
The small random increases in the number of chromatid gaps and/or isogaps in one experiment with S-9, which were not dose-dependent and not different from the untreated controls were not considered to be compound-related effects by study personnel.Overall remarks, attachments Overall remarks

A previous study revealed that 5000 mg/kg did not affect survival. Concentrations of test material in dosing solutions were verified by HPLC. Groups of animals(5/sex/dose/sacrifice time) were sacrificed by cervical dislocation 24, 48 and 72 hours after treatment.

Examinations Tissues and cell types examined Bone marrow samples were obtained from both femurs at sacrifice. Cell smears were prepared from cell suspensions. Details of tissue and slide preparation The slides were air dried, fixed in methanol and stained in 5% Giemsa. Slides were coded and scored blindly. One thousand polychromatic erythrocytes (PCE) were evaluated from each surviving animal and the frequencies of micronucleated polychromatic erythrocytes (MN-PCE) were recorded. Micronuclei were identified as darkly stained bodies with sharp contours and varying shapes such as round, almond, or ring. The ratio of PCE- N CE (normochromatic erythrocytes) in the bone marrow was determined by examining 100 erythrocytes. Evaluation criteria The test was valid if positive controls had significantly more MN-PCE than controls (62.2 in males and 34.6 in females). Statistics Statistical Analysis: The raw data on the counts of MN-PCE for each animal were transformed by adding 1 to each count and then taking the natural log of the adjusted number. The transformed MN-PCE data and the data on percent PCE were analyzed by a three-way analysis of variance looking only at main effects. Pairwise comparisons between treated vs. negative controls were done (if necessary) by a t-test usingBonferroni correction for multiple comparisons.

Positive controls valid yes Additional information on results One female dose with 1667 mg/kg test material died prior to scheduled sacrifice. The cause of death was not determined. There were no significant increases in the frequencies of micronucleated polychromatic erythrocytes (MN-PCE) in groups treated with test material (range from 0.2 to 1.6) versus negative controls (range 0.4 to 1.2). The ratios of polychromatic erythrocytes (PCE) to normochromatic erythrocytes ( N CE) (% PCE) in test animals (67.3 to 82.0) also were similar to those of negative controls (70.6 to 78.7).

Bilaterally decreased spermatogenesis in seminiferous tubules and decreased spermatozoa in the epididymes (both were graded as severe) were noted in the testes of one high dose male rat. This animal had a complete lack of mature spermatids in greater than 41% of tubules in each testicle, few spermatids beyond stage 12 of development in the seminiferous epithelium, and decreased spermatic elements in the head and tail of greater than 41% of the tubules and ducts in the epididymides. The testes of one male treated with 1200 mg/kg exhibited different testicular changes [bilateral multifocal degeneration of spermatocytes and spermatids from germinal epithelium (graded as very slight), and multinucleated spermatids]. In this rat, all stages of the cycle of the seminiferous epithelium were observed in morphologically normal tubules. The epididymides of this rat had decreased spermatic elements in the head and tail of 1-5% of ducts. Some of the ducts also contained immature spermatids. There were no effects on estrous cyclicity or ovaries of females. Observations: offspring Remarks on results including tables and figures

Study personnel concluded that the bilateral microscopic testicular changes observed in one high-dose and one mid-dose male rat were unrelated to treatment. Reasons given were that the dissimilarity of the lesions for the two animals suggested that they occurred spontaneously, and the incidence of animals with lesions (1/10 in each group) was well within that of historical controls (0-17%). Study personnel also stated that the degenerative changes in the testes of one mid-dose and one high-dose rat were not consistent with the types of lesions that have been attributed to 2-methoxyethanol (2-ME). The cell types that are most vulnerable to 2-ME are the pachytene spermatocytes and round spermatids (Chapin et al., Fund Appl. Toxicol 5:182-189, 1985). As the dose of 2-ME is increased, the number and types of cellsaffected increase up to the point that the germinal epithelium is significantly degenerated and all stages of spermatogenesis are affected (Chapin et al., Fund Appl. Toxicol 5:182-189, 1985; Miller et al., Fund Appl Toxicol 3:49-54, 1983.). In contrast, the testicular effects seen with the high dose animal treated with TGME consisted of a virtually complete lack of mature spermatids beyond stage 12. All other stages, including spermatogonia and spermatocytes, were present and appeared morphologically normal. In the mid-dose rat, the only effects noted consisted of very slight degeneration of spermatocytes and spermatids similar to those seen in historical control animals.

Study personnel also stated that the lymphoid tissues and hematologic parameters, which have been reported to be affected at doses of 2-methoxyethanol that have been associated with testicular changes (Miller et al., Fund. Appl. Toxicol. 3:49-54, 1983) were unaffected in this TGME study. Taking all factors into consideration, the testicular lesions observed in this dermal study could not be directly attributed to TGME exposure.

Overall remarks, attachments Overall remarks

Additional details for this study can be found in the Repeated dose dermal study.001 summary.

The EPA has determined that based on severe testicular toxicity in 1/10 rats given 4000 mg/kg/day and minimal decreases in developing germ cells (1-5% of semiferous tubules affected) in 1/10 rats given 1,200 mg/kg/day, the NOAEL for testicular toxicity is between 400 and 1200 mg/kg/day (Anderson, L. Triethylene glycol monomethyl, monoethyl and monobutyl ethers RM1 screening document (draft), Feb. 24, 1995). This value was reached even though it was recognized that the testicular changes in the 1,200 mg/kg/day rat were within historical control limits for Sprague-Dawley rats (0 1 7 %).

The authors state that a possible contributing factor in the development of testicular lesions at the high dose was low-level contamination of the test substance with the known testicular toxicant 2-methoxyethanol (EGME). EGME was present in the test substance at a concentration of 0.02  0.04 %, resulting in a EGME dose up to 1.7 mg/kg/day for animals in the high dose group. Given the length of the study, it is possible that EGME contributed to the testicular lesions. A comparison between the doses of EGME and TGME required to produce testicular toxicity indicated that TGME is 350 times less potent than EGME in producing testicular lesions in the rat. The dose of TGME that caused testicular toxicity (4000 mg/kg/day) is 4 times greater than the 1000 mg/kg/day limit dose generally recommended for subchronic studies.

The authors concluded that these effects were related to treatment. The severity of the lesions was primarily mild to moderate for degeneration (11/12) and minimal to moderate for atrophy (5/5), indicating that not all tubules were affected and that a limited number of cells was affected within the affected tubules. One male treated with 1200 mg/kg had severe seminiferous tubule atrophy, a complete loss of cell types in the tubules (except for Sertoli cells) and moderate Leydig cell hypertrophy (not significant from control). This was not considered to be related to treatment because of the lack of a plausible explanation for the unusual dose-response relationship (the effect at this dose was more severe than that of a higher dose) and the low incidence of animals affected at this dose level (Gill et al., Int J Toxicol 17:1-22, 1998) One male treated with 1200 mg/kg had severe seminiferous tubule atrophy and moderate Leydig cell hypertrophy (not significant from control).

The NOAEL listed is for reproductive organ toxicity. Other results are shown in section 5.4. The summary preparer-assigned NOAEL and LOAEL for testicular effects is 1200 and 4000 mg/kg/day, respectively. By contrast, the EPA has determined that the NOAEL for testicular effects is between 400 and 1200 mg/kg/day (Anderson, L. Triethylene glycol monomethyl, monoethyl and monobutyl ethers RM1 screening document (draft), Feb. 24, 1995).

Body weight and feed consumption were recorded on Day 0 of presumed gestation and from days 6 through 20 of gestation. Dams that were found dead were necropsied on day of death and subjected to the same procedures described for scheduled sacrifice. Ovaries and uterine content Rats were sacrificed on Day 20 of presumed gestation, and the thoracic and abdominal viscera were examined for gross lesions. The uterus was excised from each rat and weighed. The number and placement of implantations were recorded and sites were categorized as early or late resorptions, or live or dead fetuses. Each ovary was examined for the number of corpora lutea. Fetal examinations Fetuses were weighed, sexed, and examined for external alterations. One-half were examined for soft tissue alterations, and the remaining half were examined for skeletal alterations. Statistics Maternal and fetal incidence data were analyzed suing the variance test for homogeneity of the binomial distribution. Maternal body weight and feed consumption data, organ weight data, and litter averages for percent male fetuses, p ercent dead or resorbed conceptuses per litter, fetal body weights, fetal ossification sites, and percent fetal alterations were analyzed using Bartlett's Test of homogeneity of variances and the analysis of variance (when data were homogeneous). If the analysis of variance was significant, Dunnett's Test was used to identify the statistical significance of individual groups. If data were not homogeneous, the Kruskal-Wallis test was used when less than or equal to 75% ties were present; when more than 75% ties were present the Fisher's Exact Test was used. In cases where the Kruskal-Wallis Test was statistically significant, Dunn's Method of Multiple Comparisons was used to identify the statisticalsignificance of individual groups.

Maternal toxic effects
yes Details on maternal toxic effects One nonpregnant animal in the high dose group (5000 mg/kg/day) was found dead on day 13 of p resumed gestation. This was considered by the authors to be treatment-related. Significant numbers of rats treated with the high dose exhibited decreased motor activity, excess salivation, ataxia, and impaired righting reflex. Food consumption of high dose animals were reduced over the entire dosage period. Average maternal body weight gains of rats in the high dose group were reduced on days 6-9, 6-12, 12-16, and 6-16 of gestation. Consequently, average body weights of these animals were reduced on days 9, 12, and 16. Average gravid uterine weights of high-dose animals were also reduced.
Food consumption of rats receiving 2500 mg/kg/day was reduced during days 6-16, 6-18, and 12-16. Food consumption and average maternal body weights and body weight gains in rats receiving 1250 mg/kg/day were not significantly different from controls. Therefore, 1250 mg/kg/day was considered by study personnel to be the NOAEL for maternal toxicity.
There was no effect of TGME on the number of pregnant dams or number of copora lutea, implantations, live litter size or fetal sex ratios. Embryotoxic / teratogenic effects
yes Details on embryotoxic / teratogenic effects Fetal: Significant increases in embryo-fetal lethality (litter averages for total resorptions (1.6 versus 0.6 in control), late resorptions (0.3 versus 0 in controls), p ercentage of resorbed conceptuses (12.0 versus 4.4 incontrol) and dams with at least one resorption (81.8% versus 47.8 in control) occurred in the 5000 mg/kg group. Fetuses from rats treated with 2500 or 5000mg/kg had lower body weights than controls (3.04 and 2.56 g (respectively) versus 3.32 in controls).
There was no effect of TGME on the incidences or types of gross external or internal soft tissue malformations. Groups given 1250 mg/kg/day and higher doses of TGME had significant increases in the litter and/or fetal incidences of reversible delays in fetal ossification. Fetuses from rats given 2500 or 5000 mg/kg/day also had a significant increase in the incidence of cervical ribs. The NOAEL for developmental toxicity was considered by study personnel to be 625 mg/kg/day. Remarks on results including tables and figures

The authors remarked that the skeletal variations noted were common observations in fetuses with reduced body weights. Since only reversible delays in fetal ossification were observed in the 1250 mg/kg/day group, the actual NOAEL may be close to this concentration. The NOAEL listed under teratogenicity is the NOAEL for developmental toxicity.

ma rks The authors concluded that the NOAEL for fetal toxicity was 1500 mg/kg/day because the skeletal abnormalities observed at this dose were not unique. However, in a similar study p erformed by the same laboratory in rats (see previous record), common skeletal abnormalities were considered to be adverse. On this basis, the NOAEL for developmental toxicity in rabbits should be the dose that did not produce an increase in any skeletal abnormalities (1000 mg/kg/day). The NOAEL listed under teratogenicity is the NOAEL for developmental toxicity.

Maternal toxic effects
yes Details on maternal toxic effects Maternal: Eight rabbits treated with the 1500 mg/kg/day dose died, and three aborted. A significant number of rabbits treated with this dose exhibited decreased motor activity, labored breathing, a red substance in the cage pan, dehydration, no feces, ataxia, gastric ulceration,anogenital staining, mottled gallbladders, thin-walled stomach, reddened stomach, and fluid-filled or empty small intestines, and lower average gravid uterine weight. There was one death in the 1000 mg/kg/day group. This was considered to be possibly related to treatment. One rabbit in the low dose group aborted. Study personnel did not consider this to be related to test material because it was not dose-dependent.
There was no effect of treatment on the number of pregnant rabbits, average number of corpora lutea, implantations, live fetuses, resorptions, or fetal sex ratios.
Rabbits treated with all doses except 250 mg/kg/day gained more weight during the postdosage p eriod than controls, reflecting increased food consumption during this period. Study personnel did not consider this weight gain to be an adverse effect, as it is commonly seen in developmental studies after dosing is terminated. Details on embryotoxic / teratogenic effects Fetal: There was no effect of treatment on fetal body weight, or incidences or types of gross external or internal soft tissue malformations.

N o. of animals per sex per dose 64 p regnant females per dose. Control animals yes, concurrent vehicle Examinations Maternal examinations Clinical observations were made at least twice daily during the dosing period and daily otherwise. Maternal body weights were measured on GD 0, 6, 9, 12, 15, 18, 20, and on PND 0,4, 7, 13, 17, and 21. Food consumption was measured for the intervals GD 0-6, 6-9, 9-12, 12-15, 15-18, 18-20, and PND 0-3, 3-6, 6-9, and 9-12. Maternal animals were allowed to deliver and rear their young.
On PND 22 the dams were evaluated for body weight, liver and kidney weight and the number of uterine implants (metrial glands). Fetal examinations Pups were counted, examined externally, weighed, and sexed on PND 0 and PND 4. After examination on PND 4, litter size was standardized by random culling to either a 4:4 or 5:3 sex ratio. Litters with insufficient numbers of pups were removed from the study after culling. Litters with sufficient numbers of pups remained on study, and pups wereexamined and weighed on PNDs 7, 13, 17, 21,35, 49, and 68. Male pups were examined daily starting at PND 17 for testicular descent, and females were examined daily starting on PND 30 for vaginal opening. One male and one female pup from each litter were assigned to each of three behavioral tests. Motor activity was assessed for one hour in a Figure-8 maze on PNDs 13, 17, 21, 47, and 58. Auditory startle response was assessed on PNDs 22 and 60, and learning and memory were assessed with an active avoidance paradigm run on PNDs 60-64. Three euthanizations occurred during the course of this study. The first took place after culling and involved those dams that had failed to deliver as well as the dams and pups from litters of insufficient size or sex ratio. The second took place on PND 22 and the third on PND 68.
On PND 22 and PND 68 one male and one female pup from each litter were weighed and killed. A total of 24 of these pups were perfused in situ at each euthanization (PND 22 and PND 68 i.e., 48 animals total) and were examined for histopathologic lesions of the central and p eripheral nervous system. The brains of the remaining animals at each sacrifice were removed and separated into the telencephalon, diencephalon, medulla oblongata/ p ons, and the cerebellum. These sections were all weighed separately. Statistics Data were analyzed using the FREQ, GLM, N PA R 1WAY and LIFETEST procedures in the SAS software package, in conjunction with a set of custom-designed analysis procedures.

Based on this comment, a maternal NOAEL of 1650 was assigned by the summary preparer. This is in agreement with the maternal NOAEL derived by the EPA (Anderson, L. Triethylene glycol monomethyl, monoethyl and monobutyl ethers RM1 screening document (draft), Feb. 24, 1995).

Effect level 300 mg/kg bw/day (nominal)

Basis for effect level / Remar ks Conclusion of summary preparer, EPA. The authors arrived at a no observable effect level ( N OEL) of “equal to or greater than 300 mg/kg/day” based on decreased postnatal weight gains at 1650 and 3000 mg/kg/day. The reviewer does not believe that a N OAEL can be assigned from this study due to the unclear significance of minor reductions in body weight gains of animals at various time points and changes in startle response at 1650 and 3000 mg/kg. A NOAEL for teratogenicity of 300 mg/kg/day has been derived by the EPA (Anderson, L. Triethylene glycol monomethyl, monoethyl and monobutyl ethers RM1 screening document (draft), Feb. 24, 1995). The NOAEL listed under teratogenicity is the NO(A)EL for developmental toxicity. Maternal toxic effects
yes Details on maternal toxic effects Of the 256 mated animals assigned to this study 33, 27, 28, and 31 litters in the control to high-dose group, respectively, had sufficient pups of both sexes to be used for the behavioral evaluations. Evaluation of data from the maternal animals revealed no dose- related patterns of clinical signs of toxicity or lethality. Maternal body weights were equivalent across all groups and for all time points. N o statistically significant effects on maternal weight gain or food consumption were noted. The length of gestation was significantly increased in the high-dose group animals compared to control although this finding was “of questionable biological significance since the difference between the groups was smaller than the 14-hour breeding time.” Necropsy of maternal animals in the high- dose group revealed significantly heavier kidneys than controls. Kidney weights increased in a dose-dependent manner.

N ecropsy of maternal animals revealed that kidneys from the maternal animals exposed to 3000 mg/kg/day of TGME were significantly heavier than controls Details on embryotoxic / teratogenic effects Analysis of pup in life data revealed no significant effects for PND 0/4 p up sex ratio or for pup survival during any period. Female pups from the mid- and high-dose groups (6.7 and 6.8 +/- 0.1 g) and male pups from the high- dose group (7.0 and 7.1 +/- 0.1 g) were significantly heavier than their control cohorts on PND O (6.2 and 6.7 +/- 0.1 g for females and males,respectively). Pups from these same groups gained significantly less weight in the period from PND 4 to PND 21. Although born heavier, the male pups from the high-dose group were significantly lighter than the control pups at the end of the study on PND 68 (440.7 +/- 6.0 vs. 462.4 +/- 4.8 g). Final body weights (PND 68) of mid and high dose females and mid-dose males were not significantly different from control.
Evaluation of pup development through the determination of vaginal opening revealed no differences between groups. Male pup development, as gauged by time of testes descent, was shown to be significantly advanced in the pups from the mid- and high-dose groups. Evaluation of the behavioral data generated during the course of this study indicated no dose-related effects on motor activity or active avoidance data. Significant effects on auditory startle response p arameters were noted. In particular, the auditory startle amplitude (magnitude of the startle reflex) was increased in male and female pups in the high-dose group on PND 22. Auditory startle amplitude was also increased for male pups on PND 60 and a similar trend of smaller magnitude was observed in PND 60 females. When startle latency (time to maximum startle reflex) was examined, the pups showed no consistent effect on PND 22, but both male and female pups demonstrated a decrease in the startle latency on PND 68.

N ecropsy of weanling and adolescent pups revealed no findings that could be related to treatment. Histopathological assessment of the peripheral and central nervous systems of the p ups showed no treatment related lesions in any group. Applicant's summary and conclusion Conclusions“In conclusion, TGME administered by gavage to pregnant and lactating CD" (SpragueDawley) rats resulted in no overt signs of maternal toxicity. In addition, no discernible effects were noted in the offspring on motor activity, active avoidance, or neuropathology at exposures up to 3000 mg/kg/day. Exposure to TGME at 3000 mg/kg/day resulted inincreases in auditory startle amplitude and decreases in latency to maximum startle, but no changes in the habituation p rocess evaluated in the auditory startle test. The significance of these auditory startle observations with regard to the condition of the test animals is notclear. Exposure to TGME at levels of 1650 and 3000 mg/kg/day produced developmental toxicity evidenced by decreased p ostnatal weight gains. Therefore, the no observable effect level" ( N OEL) for this study is considered to be equal to or greater than 300 mg/kg/day.” Developmental toxicity / teratogenicity Taupin BF DOT 1993.005 UUID IUC5-a4c4b344-0ebc-4eb2-8ae3-6cfb34716529 Dossier UUID 0

Further details on study design Groups of 10 female rats were dosed by oral gavage with 25, 150 or 1000 mg/kg/day test material on days 7-17 of gestation. Additional groups of females were sham dosed (negative control) or dosed with 1000 mg/kg/day ethylene glycol diethyl ether ( p ositive control). Animals were allowed to litter naturally, and any that did not deliver by day 25 of gestation were killed. Dams and surviving pups were killed on day 5 of lactation. Examinations Maternal examinations Body weights were recorded on days 1, 7 and 21 of gestation and on day 5 of lactation (or attermination for animals that did not reproduce). Food intake was recorded over days 1 to 7 and 7 to 17 of gestation, day 17 of gestation to day 1 of lactation and days 1-5 of lactation. Ovaries and uterine content Uteri of all dams were examined for implantation sites. Fetal examinations The birth index [total number of pups born (live and dead) x 100/ number of implantation sites], live birth index (number of pups alive at day 1 of lactation/ total number of pups born x 100) and viability index (number of pups alive on day 5 of lactation/ number of pups alive on day 1 of lactation x 100) were calculated for each litter and group.

Maternal toxic effects no effects Details on maternal toxic effects There was no effect of Brake Fluid DOT4 on maternal body weight of food intake. Embryotoxic / teratogenic effects no effects Details on embryotoxic / teratogenic effects Mean litter weights of low dose (25 mg/kg/day) animals were slightly lower than negative controls at birth (79 +/- 24 g vs. 90 +/- 23 g in sham control) and on day 5 of lactation (109 +/- 29 g vs. 133 +/- 34 g in sham control). In contrast, mean litter weights of high dose animals were higher than negative controls at birth (97 +/- 10 g) and on day 5 of lactation (150 +/- 24 g). The authors stated that the reduction at 25 mg/kg/day could be related to slightly smaller litter sizes (the birth index was 85 +/- 15 vs. 95 +/- 7 in the sham control). Two rats in this group had a lower number of implant sites (8 and 6) than the others (ranged from 15-19), which led to a decrease in the number of pups delivered(5 in each of the animals vs. 13-18 in the others). Another low dose animal that had 16 implant sites only delivered 9 p ups. The birth index of animals treated with 150 (94 +/- 6) or 1000 mg/kg/day test material (95 +/- 6) was similar to the sham control (95 +/- 7). There was no effect of treatment on the number of dead pups (4 in control vs. 1 in each treated group). There were no treatment-related necropsy findings. There was no effect of treatment with Brake Fluid DOT 4 of the duration of gestation, the number offemales littering, the mean number of implant sites, or the live birth index or viability index. Based on these data, the authors concluded that 1000 mg/kg/day Brake Fluid DOT4 did not cause fetal growth retardation or embryolethality.
By contrast, the positive control animals lost weight from days 7 to 21 of gestation. All nine p regnant animals treated with ethylene glycol diethyl ether (EGDE) resorbed their litters. Most animals treated with EGDE had enlarged livers and/or spleens. Remarks on results including tables and figures

It is not known whether the decreased mean litter weights or birth index at 25 mg/kg/day or the increased mean litter weights at 1000 mg/kg/day are significantly different from control, since statistical analyses were not performed. However, these findings do not appear to be related to treatment since they are not dose-dependent. Since the investigators concluded that 1000 mg/kg/day Brake Fluid DOT4 did not cause fetal growth retardation or embryo or fetal lethality, the NOAEL for these effects is 1000 mg/kg/day. The NOAEL listed under teratogenicity is the NOAEL for developmental toxicity.

N onacclimated domestic sewage organisms were used as seed in the test. Domestic wastewater was filtered through glass wool and added (3 ml/bottle) as seed material to clean BOD bottles. A buffered, aerated solution containing minerals was then added. Small amounts of test material were added from a 0.1 % stock solution to yield concentrations of 3, 7 and 10 mg/l. A control with no test material also was run. At least two of the concentrations were tested in duplicate. Dissolved oxygen (DO) was monitored five times during the course of the 20-day test. The solution was reaerated when the DO dropped below 4.0 mg/l. Reaeration (if needed) was accomplished by dividing the BOD bottle contents between 2 BOD bottles, sealing, shakingthem twenty times, returning contents to the original BOD bottle, recording the oxygen level, resealing, and returning the BOD bottle to the incubator. Samples were analyzed routinely for nitrites and nitrates. Results of the tests were expressed in terms of % biooxidation calculated as the cumulative oxygen uptake for the test material minus a control x 100 / initial concentration of test material x theoretical oxygen demand.

The water was aerated with oil-free air to > 60% saturation. The water was regularly tested for the p resence of contaminants and microbes. Test conduct: Glass aquaria (30 x 22 x 24 cm3) containing 10 liters of test water were loaded with 10 zebra fish each (0.23 g test fish/ liter of water). Concentrations tested were based on the results of 2 p reliminary studies. Zebra fish were exposed over a 96-hour period to a range of concentrations spaced by a factor of about 2.2 (46.4, 100, 215, 464 and 1000 mg/l). An untreated control was included. Fish were placed in the aquaria within 25 minutes of addition of test material. They were not fed during the test. The water was maintained at 23 degrees under slight aeration. Fish were observed 1, 4, 24, 48, 72 and 96 hours after exposure. The pH, temperature and oxygen content were measured 1, 24, 48, 72 and 96 hours after exposure. The LC0, LC50 and LC100 concentrations and the NOEC were to be determined for each time point. The concentrations of test material present at 1 and 96 hours were analytically confirmed.

Each vessel was filled with 1 liter of standard water (hardness 25 mg/l as CaCO3) and covered with glass. A stock solution of test material was made by dissolving it in either acetone or 2- p ropanol (not specified). Various volumes of stock solution were added to the test vessels to increase test concentrations geometrically (in increasing ratios of 3.2). Test solution was renewed daily. Guppies were fed 0.5 hours before each renewal with commercial fish food. Oxygen content, water temperature, and viability offish were monitored. Oxygen content remained above 5 mg/l, and temperature was 22 +/- 1 degrees C. Any other information on materials and methods incl. tables

Details on test conditions Organisms were individually introduced in 100 ml glass vials containing 50 ml of test solution (mineral water with Ca = 78 mg/l, Mg = 24 mg/l, N a = 5 mg/l, K = 1 mg/l, SO4 = 10 mg/l and Cl = 4.5 mg/l). Hardness and pH of the test solutions were measured daily (except weekends). Values were within the guidelines of pH = 8.0 +/- 0.3 and hardness = 250 +/- 20 mg/l as CO3. Daily measurements of dissolved oxygen ranged between 8.6 and 9.2 mg/l. Temperature was monitored continuously. The test was conducted at 25 +/- 2 degrees C. A 16:8 light:dark p hotoperiod was employed. Light intensity at the air/water interface ranged between 300 and 500 lx. Test solutions were changed daily (with the exception of weekends). The organisms were fed with Chorella vulgaris (6 x 10E6 cells/50 ml), Raphidocelis subcapitata (3 x 10E6 cells/50 ml) and 25 microliters/50 ml of a stock solution (5 g/l) of commercial fish food. Ten replicates (one individual per each) were used per treatment and control. A range of 5 concentrations spanning those causing 0-100% inhibition of reproduction were used. The criterion for estimating the effect of the material on the reproduction of the organism was the EC10 at 7 days. The EC10 value was calculated according to the method of Hill (Garrie et al., Water Res. 24:59-65, 1990 and Vindimian et al., J Appl Biochem 5:261-268, 1983). The following criteria had to be met in order for the test to be considered valid: control survival of > 80%, < 20% of males at Day 7 in each batch, > 60% of control females having three broods, and control females having at least 15 offspring in 7 days.

Test conditions Test temperature 21.6 deg C Details on test conditions A SAG 86.81 culture of Scenedesmus subspicatus (10,000 to 16,000 cells/ml) was maintained at 21 to degrees C. Cells in suspension were treated with 0 (control), 10, 25, 50, 100 or 250 mg/l test material in quadruplicate. Test concentrations were chosen based on the results of a p reliminary test. Fluorescence of vials containing treated cells was determined 0, 24, 48, 72 and 96 hours after treatment in a fluorimeter (at wavelengths from 300 to 780 nm). Fluorescence of 2 blank vials containing test material (at each concentration) and medium without cells was subtracted from values obtained for test vials. The values for the four tests were averaged and a standard deviation was calculated. The pH of solutions was determined before and at the end of the test. Fluorescence was converted to cell number ( N ) using the equation fluorescence = N /ml - 4748.47/220.024. The data were analyzed according to the method of Tallarida and Jacob (The Dose-Response Relation in Pharmacology, p . 98- 103, Springer Verlag, 1979).

The study was translated into English from German by the reviewer. Test substance purity data came from an IUCLID document for CAS No. 112-25-4 p repared by the European Chemicals Bureau, dated 11-FEB-2000.

Fluorescence measures chlorophyll content, and chlorophyll content is a measure of biomass. In a study described by Herman et al. (Aquatic Toxicol 18:87-100, 1990), 4 different ways of measuring biomass were checked for sensitivity (cell number, absorbance, chlorophyll content and dry weight). Measuring cell number was the most sensitive means of assessing algal cell growth, followed by absorbance and chlorophyll content, which were of equal utility. Sincemost test methods use absorbance for calculating biomass, and results of tests measuring chlorophyll content and absorbance are similar, tests employing fluorescence to measure chlorophyll content should be as sensitive as those employing absorbance as a means of assessing algal biomass.

Growth medium chemistry (other than pH), source of dilution water, size of exposure vessels and volumes of solution, method of preparation of test solutions and light conditions were not described.

The integrity of the epidermal membranes was first assessed by measuring permeability of membranes to tritiated water. Epidermal membranes displaying permeability constants greater than 1.5 x 10E-3 cm/hr were deemed to have been damaged during preparation and were rejected. Results and discussions Signs and symptoms of toxicity no effects Dermal irritation not examined Remarks on results including tables and figures

The mean steady state of absorption for triethylene glycol monobutyl ether was 22.2 micrograms/cm2/hr (SD +/- 8.59), which was 100-fold less than that of ethylene glycol monomethyl ether. Test material did not increase permeability of the membrane (damage ratio of 1.26).

Overall remarks, attachments Overall remarks

Absorption of ethylene glycol monomethyl ether (EGME), triethylene glycol monomethyl ether (TGME),and triethylene glycol monoethyl ether (TGEE) also were tested in this study. The rate of absorption of EGME was220 micrograms/cm2/hr. The rate of absorption of TGME was 34.0 micrograms/cm2/hr and the mean damage ratio was 3.36 (small increase in permeability). The rate of absorption of TGEE was 24.1 micrograms/cm2/hr, and the mean damage ratio was 1.37 (no increase in permeability).

They were acclimated to the laboratory at least one week prior to treatment, and were approximately 8 weeks old at the beginning of the study.Animals were housed one per cage ( p rebreeding) or two per cage (one per sex during breeding) in stainles ssteel cages. Dams were housed one per cage (with litter) in plastic cages with ground corn cob nesting material from approximately gestation Day 19 through lactation, under a 12 hour light/dark photocycle. Room humidity and temperature were maintained at 40-70% and 22 +/- 1 degrees C. Room air was exchanged approximately 12-15 times/hour. Animals were allowed free access to food and municipal water. There were no contaminants in the feed or water that would interfere with the study. Administration / exposure Route of administration oral: feed Vehicle unchanged (no vehicle) Details on oral exposure Diet preparation: Diets were prepared by serially diluting a concentrated test material-fee mixture ( p re-mix) with ground feed. Pre-mixes were prepared periodically throughout the study based on stability data. Diets were prepared weekly for two weeks prior to breeding. Concentrations of material in the diets were calculated from body weights and feed consumption data. To avoid potential overdosing during the breeding period, co-housed animals were provided with the female diet, which was of lower concentration. Following breeding. The male diet was prepared weekly until necropsy. During gestation and lactation, female were p rovided with the same concentrations as given during breeding. Analytical verification of doses or concentrations
yes Details on analytical verification of doses or concentrations Representative samples from the test diets were analyzed at least once to ensure homogeneous distribution of test material at the lowest and highest concentrations. All test diets from the first mix were analyzed prior to dosing using gas chromatography-mass spectrometry (GC-MS), and an internal standard. Reference samples (one/dose/mix) were retained and stored in sealed vials.

Duration of treatment / exposure Females: dosed daily for two weeks prior to breeding, through breeding (two weeks), gestation (three weeks), and through postpartum Day 4. Males: dosed for two weeks prior to breeding and continuing through breeding (two weeks) up until necropsy.

Control animals
yes, p lain diet Details on study designStudy conduct: Groups of 12 male and 12 female CD rats randomly assigned to four treatment groups and were fed diets supplying concentrations of 0 (control), 100, 300 and 1000 mg/kg/day. Females were dosed daily for two weeks prior to breeding, through breeding (two weeks), gestation (three weeks), and through postpartum Day 4. The males were dosed for two weeks prior to breeding and continuing through breeding (two weeks) up until necropsy. Females that delivered were necropsied on post- p artum Day 5. Pups were euthanized on p ostnatal Day 4.
During breeding, each female was caged with a male from the same group until pregnancy occurred ( p resence of sperm in vaginal lavage sample evaluated daily or presence of a copulatory plug) or two weeks had elapsed. The day on which pregnancy was detected was considered lactation Day 0. If mating did not occur after two weeks, the animals were separated without further opportunity for mating. Examinations Observations and examinations performed and frequency Cage-side examinations for skin, fur, mucous membranes, respiration, nervous system function (including tremors and convulsions), animal behavior, moribundity, mortality, availability of feed and water, and litter observations were conducted twice daily. Females were observed for signs of parturition on or about gestation Day 20. Females that delivered received clinical examinations on lactation Days 0, 1 and 4. Females that failed to mate or deliver were subjected to hand-held evaluations weekly.
Detailed clinical observations were conducted on all rats before exposure and weekly throughout the study. Mated females underwent these examinations on gestation Day 0, 7, 14, and 20, and on lactation Day 3. The examination included cage-side, hand-held and open-field observations.
All rats were weighed prior to exposure, twice during the first week of the study and once during the second week. Male body weights continued to be recorded weekly throughout the study. Presumed pregnant females were weighed on gestation Day 0, 7, 14 and 20. Females that delivered litters were weighed on lactation Days 1 and 4. Females that failed to mate or deliver a litter were not weighed during the gestation or lactation phases.
Feed consumption was determined prior to exposure on twice during the first week of exposure. It was then determined once a week during the pre-breeding phase. It was not determined during breeding. After breeding, was determined once a week for males and on gestation Days 0, 7, 14, and 20 for mated females. After parturition, feed consumption was measured on lactation Days 1 and 4. Feed consumption was not recorded for females that failed to mate or deliver a litter.
Functional tests (sensory evaluation, rectal temperature, grip performance and motor activity) were conducted prior to exposure and during the last week of the treatment period (lactation Day 4 for females).
A timed urine volume (overnight, 16 hours) was obtained from all male rats (nonfasted) during the week prior to scheduled necropsy. Urine was analyzed for colour, appearance, specific gravity, volume, p H, bilirubin, glucose, p roteins, ketones, blood and urobilinogen. Urine collected by manual compression of the bladder was pooled from each group and analyzedmicroscopically for microsediment. Sacrifice and pathology On the day prior to the scheduled necropsy, all males and females in each group were fasted overnight. At necropsy, the animals were anesthetized with CO2 and blood was collected from the orbital sinus. Blood samples were not collected from females that failed to deliver. Blood was analyzed for hematocrit, hemoglobin concentration, red blood cell count, total and differential which blood cell counts, p latelet count, red blood cell indices (mean corpuscular hemoglobin, mean corpuscular volume and mean corpuscular hemoglobin concentration), and p rothrombin time. Serum was analyzed for alkaline phosphatase, alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin, cholesterol, creatinine, sodium, p otassium, p hosphate, chloride, calcium, glucose, total bilirubin, total protein and urea nitrogen.
Males were terminated and necropsied on test Day 34. Females that delivered were terminated and necropsied on post- p artum Day 5. Females that did not deliver were terminated and necropsied at least 24 days after the last day of the mating period. Post-mortem examinations included a gross necropsy of all adults (which included a gross examination of the brain, p ituitary and eyes), with collection of organ weights (testes, epdidymides, seminal vesicles with coagulating gland, p rostate, ovaries, liver, kidneys, adrenals, thymus, spleen, brain, thyroid/ p arathyroid, and heart) and extensive histopathologic examination of tissues (adrenals, aorta, auditory sebaceous glands, bone (including joint), bone marrow, brain, cecum, cervix, coagulating glands, colon, cranial nerve, duodenum, epididymides, esophagus, eyes, gross lesions, heart, ileum, j ejunum, kidneys, lacrimal/Harderian glands, larynx, liver, lungs, mammary gland, mediastinal lymph node and tissues, mesenteric lymph node and tissues, nasal tissues/ p harynx, oral tissues, ovaries, oviducts, p ancreas, p arathyroid glands, p eripheral nerve, p ituitary, p rostate, rectum, salivary glands, seminal vesicles, skeletal muscle, skin and subcutis, spinal cord, spleen, stomach, testes, thymus, thyroid gland, tongue, trachea, urinary bladder, uterus and vagina) from control and high dose animals. The histopathological examination of the testes included a qualitative assessment of states of spermatogenesis. Statistics Statistical analyses: Parental body weights, gestation and lactation body weight gains, litter mean body weights, feed consumption, urine volume, urine specific gravity, coagulation, clinical chemistry data, hematological data and organ weights were first evaluated by Bartlett's test for homogeneity. Parametric and nonparametric data were then analyzed by the appropriate analysis of variance (ANOVA). If the ANOVA was significant at alpha = 0.05, a Dunnett's test (alpha = 0.05) or the Wilcoxon Rank Sum test with Bonferroni's correction was performed. Feed consumption data were excluded if the feed was spilled or scratched. Females failing to deliver a litter were excluded from analyses of gestation and lactation body weight, feed consumption and organ weights. Detailed clinical observation and sensory evaluation scores were analyzed using a z-test of proportions (at alpha = 0.05). Rectal temperature and grip p erformance were analyzed by an analysis of covariance. Motor activity was analyzed by a repeated measure design.

All animals survived to termination. There was a slight treatment-related decrease in body weights of males and females given 1000 mg/kg/day. Decreased maternal body weights persisted throughout the gestation and lactation phases of the study. Decreased feed consumption was noted in high dose males and females during the p rebreeding period and in high dose females during gestation.
Females given 1000 mg/kg/day had treatment-related increases in serum ALT and ALP activities, along with increases in relative liver weight. These effects corresponded with treatment-related histopathologic changesin the liver that consisted of very slight panlobular hepatocyte hypertrophy. Males given 1000 mg/kg/day had treatment-related increases in relative liver weight, which corresponded with the histological alteration of very slight p eriportal hepatocyte hypertrophy. At 1000 mg/kg/day, other findings of lesser significanceincluded slightly increased blood urea nitrogen and decreased absolute thymus weights in females, and decreased urine pH and increased relative kidney weights in males. Additional histopathologic findings of minor toxicological significance at 1000 mg/kg/day included very slight diffuse acinar hypertrophy of the submandibular salivary gland in males, and very slight atrophy of the mesenteric adipose tissue in females.
There were no adverse effects of DGHE on neurological function. There were no adverse gross or histopathologic findings in the reproductive organs of high dose males or females.

Based on these results, the no-observed-adverse-effect level ( N OAEL) for general toxicity was 300 mg/kg/day. The NOAEL for neurological effects was 1000 mg/kg/day, the highest dose level tested. Analyses of all test diets from the first mix of the main study revealed mean concentrations ranging from 92.5 to 104% of targeted concentrations. Analyses of the low dose female and high dose male diets indicated that the diets were homogeneous. Analyses confirmed that the 10% p remix was stable fo r 14 days and that the test diets were stable for 8 days at concentrations ranging from 0.120 to 0.359%, which encompass the range of dietary concentrations used in the study. Remarks on results including tables and figures
A limit dose of 1000 mg/kg/day was selected as the high dose level based on data obtained in a p reliminary range-finding study. The authors reported no-observable-effect-levels ( N OELs) of 300 mg/kg/bw/day for general toxicity and 1000 mg/kg/bw/day for neurological effects. Data in this summary pertain to exposed adult animals only.

The purity of the test material (approximately 100%) was listed on a material safety data sheet attached to the study report. Test animals Species rabbit Strain N ew Zealand White Sex male/female Details on test animals and environmental conditions Fifty six rabbits (28 p er sex) were received at 12-13 weeks of age. They were acclimated for 2 weeks before dosing. They were maintained on a restricted diet (4 oz/day/rabbit) during this p eriod. Only rabbits with body weights within +/- 20% of the population mean for each sex (2-3kg) were used. Administration / exposure Type of coverage occlusive Vehicle unchanged (no vehicle) Details on exposure Five animals/sex were randomly chosen to receive vehicle (control), or 0.11, 0.32 or 1.07 ml/kg/day test material (100, 300 or 1000 mg/kg/day).
Prior to the first dose (and subsequently, as needed), fur was clipped from the dorsal area of the trunk of the animals (approximately 10% of body surface area). Care was taken to avoid abrading the skin. Test material was applied topically as a neat liquid to the clipped intrascapular region of the back. Dosages were determined based on individual body weights measured on Days 0 and 7. Control animals were treated with water at a dose of 1.0 ml/kg/day. The dose site was covered with an 8- p ly gauze patch and a piece of polyethylene sheeting. The animals were then wrapped with a Lycra/Spandex jacket held in place with Velcro strips. The wrappings were removed after 6 hours of exposure. Animals were dosed daily, Monday through Friday of the first week and Monday through Thursday of the second week. Food and water were available ad libitum after treatment was initiated.

Examinations Observations and examinations performed and frequency Animals were examined daily for signs of toxicity before dosing (with particular attention given to the application site). Skin irritation was graded according to a similar scale as Draize (1 = very slight, 2 = well-defined, 3 = moderate to severe, 4 = severe). Body weights were measured on Days 0, 7, 10, and 11 (at termination). Animals were fasted during the night prior to termination. The body weights used for determining body weight gains were those obtained on Day 10. Food consumption was determined on Days 2, 4, 6, 7, 9, and 10.
Blood was obtained from all animals via cardiac puncture just prior to termination on Day 11. The following hematological parameters were measured: erythrocyte count, hemoglobin,hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), total leukocyte count, p latelet count, and differential leukocyte count. Clinical chemistry measurements included creatinine, fasted glucose, total and direct bilirubin, total protein, albumin, globulin, calcium, p hosphorus, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase, sorbitol dehydrogenase, sodium, p otassium, chloride, urea nitrogen. Sacrifice and pathology Complete necropsies were performed after animals were euthanized. The liver, kidneys, adrenals, brain, heart and testes (males) were weighed. The following tissues were fixed and examined histologically (in the control and high dose groups): all lesions, brain, p ituitary, heart, thymus, thyroid (with parathyroid), adrenals, liver, kidneys, testes and epididymis (males), uterus and ovaries (females), spleen, mesenteric lymph nodes, and sternum with marrow. Treated and untreated skin from all groups was fixed and examined. The spinal cord, sciatic nerve, eyes, salivary glands (submaxillary), aorta, trachea, lungs with mainstem bronchi, esophagus, stomach, small and large intestine, p ancreas, gallbladder, p rostate, accessory sex glands, mammary gland, urinary bladder, mediastinal lymph nodes, and gastrocnemius muscle were also fixed and saved for analysis (if necessary). Statistics Food consumption, body weight and organ weight data analyzed using Levene's test for homogeneity of variance, analysis of variance, and pooled variance t-tests (if homogeneous). Heterogeneous data were analyzed using an analysis of variance for unequal variance and separate variance t-tests. Frequency data were compared with Fisher's exact tests.

Erythema was observed in 5/5 and 4/5 high dose (1000 mg/kg/day) males and females (respectively) by Day 4. Edema at the application site was observed in all males from the high dose group starting on Day 3. These findings were generally of limited severity (Grade 1). However, erythema scores of 3 or 4 were noted in 2 high-dose females. Barely perceptible (Grade 1) erythema and/or edema was noted at various times in all males and females from the mid dose group (300 mg/kg/day) and occasionally in all males and one female in the low dose group (100 mg/kg/day). Fissuring at the skin was noted in males from all treatment groups and all females in the mid and high dose groups. Encrustation was found in 2 and 3 high dose males and females, respectively. Ecchymosis was found in 1 and 3 high dose males and females, respectively.
A significant reduction in food consumption was found in high dose males during the first week. There was no significant effect of treatment on weight, weight gain, or organ weights (except for increased weight gain in males from the low dose at Day 11). There was no effect of treatment on any hematological or clinical chemistry variable.Gross pathological and histological changes were limited to the skin at the treated area.
Gross findings included crusting or scaling dermatitis, scratches or fissures. Acanthosis and hyperkeratosis were found in all high and mid-dose animals, and in 3 males and 4 females from the low dose group. Superative epidermitis was noted in 9/10 animals from the high dose group. The underlying dermis showed dose-related changes ranging from acute inflammation with edema, hemorrhage, and necrotizing dermatitis to dermal fibrosis.

Prior to randomization, rabbits were fasted (19-23 hours), and blood samples were taken from the central ear artery for control hematological and biochemical evaluations. Healthy rabbits (4- 4.5 months of age) were randomly divided into groups of 5 p er sex. Administration / exposure Type of coverage semiocclusive Vehicle unchanged (no vehicle) Details on exposure Prior to study initiation, hair was removed from the back of each rabbit with an electric clipper. Rabbits were shaved as necessary during the course of the study to prevent the test material from becoming matted in the hair and to facilitate accurate observations. One group of rabbits was left untreated and the other was treated with 1000 mg/kg test material, five days per week for 3 weeks. Dose volumes were calculated based on the specific gravity of test material (as determined at the study site) and the body weight of animals (determinedweekly). Test material was placed on the back using a 5 cc plastic syringe. A glass rod was used to evenly distribute the dose over the test site. Following dosing, test sites (of all animals, including controls) were wrapped with gauze bandaging and Dermiform tape and plastic restraint collars were attached to the rabbits. Collars were removed after 6 hours, and test sites (of all animals, including controls) were washed with tepid tap water and dried with paper towels.

Food consumption was estimated daily based on a visual assessment of remaining food. Body weights were recorded weekly. Rabbits were scored immediately prior to each dosing for dermal irritation in accordance with the Draize method. Blood samples taken from the central ear artery of animals at study termination were analyzed for standard hematological (total and differential leukocyte count, erythrocyte count, hemoglobin, hematocrit, p latelet count, reticulocyte count, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration) and biochemical (sodium, p otassium, chloride, calcium, p hosphorus, total bilirubin, gamma glutamyltranspeptidase, aspartate aminotransferase, alanine aminotransferase, ornithine carbamoyltransferase, urea nitrogen, creatinine, total protein, albumin, globulin, cholesterol and glucose) p arameters.

There were no significant differences in body weights or food consumption between treated or control groups. Some hematological and biochemical values from treated animals were different from controls at termination. However, since the same changes were noted in blood samples taken from the animals prior to treatment, they were not considered by the investigators to be related to treatment. Mild to moderate desquamation and fissuring of skin was noted in most rabbits after 2 to 3 weeks of treatment with test material. This was confirmed microscopically and consistedof trace acanthosis and trace to moderate dermatitis. Testicular degeneration (scored as trace in severity) , occurred in one rabbit each from the TGEE and TGME-treated groups. This lesion was characterized by the presence of spermatid giant cells, focal tubular hypospermatogenesis, or cytoplasmic vacuolization. The pathologist stated that “random occurrence of this lesion was suggestive of its spontaneous nature and was not test article related. A high incidence of similar changes of spontaneous nature in normal New Zealand White rabbits has been reported by Morton et al. in "Vet Pathol 23: 176-183, 1986 and Vet Pathol 23: 210-217, 1986.”
Based on the results, the investigators concluded that in this study, there was no systemic toxicity induced by treatment with 1000 mg/kg/day test material. Therefore, the NOAEL is 1000 mg/kg/day. Remarks on results including tables and figures

Toxicity of triethylene glycol monomethyl (TGME, CAS No. 112-35-6) and monoethyl ethers (TGEE, CAS No. 112-50-5) at 1000 mg/kg also was tested in this study. The skin effects noted for triethylene glycol butyl ether were more severe than those for TGME and TGEE.

True negative controls Positive controls yes Positive control substance sodium azide Also used 4-nitro-o- p henylenediamine and 2-aminoanthracene Remarks Details on test system and conditions Test material was diluted in DMSO to a stock concentration of 100 mg/ml. Dilutions of the stock solution were made on each day of testing. Dilutions were made such that 100 microliters of the dilution would deliver the required dose. Concentrations were verified gravimetrically. S-9 liver homogenate was prepared from Aroclor 1254-induced Sprague-Dawley male rats. For tests with metabolic activation, 0.5 ml of S-9 mix containing 50 microliters of S-9 was added p er plate.Preliminary toxicity tests with one plate per test concentration were performed using strain TA100 (in the absence and presence of S-9). Ten concentrations were tested. Toxicity was assessed by observing growthinhibition of the background lawn and/or a reduction in the number of spontaneous mutants. Each test chemical was tested in triplicate at 5 doses that spanned a range from relativelynontoxic to moderately toxic (0.03, 0.1, 0.3, 1 and 3 mg in the absence of S-9 and 0.1, 0.3, 1, 3, and 10 mg in the presence of S-9). Concurrent solvent (DMSO) and positive controls were run without S-9 as follows: 0.01 mg 4-nitro-o- p henylenediamine in strains TA98 and TA1538, 0.01 mg sodium azide in strains TA100 and TA1535, and 0.06 mg 9-aminoacridine in strain TA1537. The positive control used in all strains incubated with S-9 was 0.01 mg 2-aminoanthracene.Revertant colonies were counted after 48-72 hours of incubation (temperature was not listed). The criterion for significance was a greater than 2-fold increase in mutants with respect to the solvent control. Evaluation criteria The tests were considered valid if all positive controls produced a greater than 2-fold increase inthe number of mutants over control (both in the absence and presence of S-9). The number of spontaneous revertants in the solvent control should be within the historical 95% confidence range at the laboratory.

In the presence of S-9, 10 mg/ p late affected growth and concentrations equal to or greater than 30 mg/ p late obliterated growth.
The average number of revertants in the solvent controls were 24 (TA98), 97 (TA100), 18 (TA1535), 8 (TA1537) and 8 (TA1538). The average number of revertants in cultures incubated with test material ranged from 15-26 (TA98), 52-95 (TA100), 17-26 (TA1535), 3-9 (TA1537), and 8-11 (TA1538).
In the presence of S-9, the average number of revertants in the solvent controls for strains TA98, TA100, TA1535, TA1537 and TA1538 were 24, 79, 9, 8, and 22 (respectively). The average number of revertants in cultures incubated with test material and S-9 ranged from 9-35 (TA98), 28-92 (TA100), 5-13 (TA1535), 2-7 (TA1537), and 3-23 (TA1538).
The test substance was judged to be nonmutagenic. The tests were valid, as all positive controls p roduced a greater than 2-fold increase in the number of mutants over control (both in the absence and presence of S-9). The number of spontaneous revertants in the solvent control was within the historical 95% confidence range at the laboratory.

Remarks Ethylmethanesulfonate was also used as a positive control. Details on test system and conditions CHO-K1-BH4 (subclone D1) cells were first treated with seven concentrations of test material (from 0.01 to 10 mg/ml) to select test concentrations that would not result in excessive toxicity.

In the definitive test without metabolic activation, 5 x 10E6 cells were inoculated into culture flasks containing test medium and incubated at 37 degrees C for 20-24 hours before treatment. Test material (0.25, 0.75, 1, 1.5 and 2.0 mg/ml), DMSO solvent (20 micrograms/ml), medium, or positive control (200 micrograms/ml ethylmethanesulfonate) were added to the cultures and cells were incubated for 5 hours. After the 5 hour exposure, each flask was rinsed with buffered saline, fresh medium was added, and cells were incubated for an additional 18-24 hours. For the tests in the presence of metabolic activation, the same procedure was used with the exception that 1.0 ml of S-9 activation mixture (from Aroclor 1254-induced Sprague-Dawley male rats) was added to the flasks, serum was omitted from the culture medium, the treatment period was 2 (instead of 5) hours, test material concentrations were 0.1, 0.25, 0.75, 1.0, 1.5, 2.0 and 2.5 mg/ml), and dimethylnitrosamine (200 microliters/ml) was the positive control. DMSO vehicle and all concentrations of test material were tested in duplicate.
Cytotoxicity was determined 24 hours after exposure. At 2-3 day intervals after treatment, 5 x 10E5 cells from each culture were subcultured. After at least 7 days, cells were dissociated and replated at 2 x 10E5 cells in 5 dishes (for assessment of mutations) and at 100 cells/dish in 4 dishes (for assessment of plating efficiency) in medium containing 6-thioguanine (2micrograms/ml). These cultures were incubated for 6-8 days. Cells were then fixed and stained for counting with a Coulter Counter. Evaluation criteria Criteria for a positive response were not fully described. Statistics The numbers of mutants/10E6 total cells and per 10E6 viable cells were calculated. Mutation data were analyzed by the method of Irr and Snee (Mut Res 15:109-118, 1979) after Box-Cox transformation (J Roy Stat Soc 26:211-252, 1964), before parametric analysis using the Student's t test. Results and discussions Test results Species/strain Chinese hamster Ovary (CHO) Metabolic activation with and without Test system strain/cell type: Chinese hamster Ovary (CHO) Genotoxicity other: weakly positive in the presence of S-9. Cytotoxicity yes Cytotoxic concentration: 2.0 mg/ml Vehicle controls valid no data N egative controls valid no data

Positive controls valid yes Additional information on results Cell viability was not affected by test material concentration up to approximately 750 mg/ml in the absence of S-9 and 1 mg/ml in the presence of S-9. A concentration of 2.0 mg/ml caused 100% lethality. The plating efficiency for all concentrations was not affected by test material concentration(up to 2 mg/ml).
Test material did not produce a dose-related increase in the number of mutants per 10E5 viable cells in the absence of S-9. In the presence of S-9, increases in the mutation frequency occurred that were not dose-related and were inconsistent between duplicate cultures. A linear regression analysis of the data showed a significant trend for the combined data from the two tests (r=0.82, p = 0.0035). Both positive controls produced highly significant increases in the number of
mutants. Genetic toxicity in vitro.003 UUID IUC5-46e9082c-af12-467f-a4e3-33f1ed7988bc Dossier UUID 0

Remarks Ethylmethanesulfonate was also used as a positive control. Details on test system and conditions The concentrations tested were determined by the results of a previous HPRT mutation test (see above).

In the definitive test without metabolic activation, 2-3 x 10E6 cells were inoculated into culture flasks containing test medium and incubated at 37 degrees C for 20 hours before treatment. Test material (0.75, 1.0, 1.6 and 2.0 mg/ml), DMSO solvent (5 micrograms/ml), medium, or positive control (100 micrograms/ml ethylmethanesulfonate) and bromodeoxyuridine (BrDU; 3 micrograms/ml) were added to the cultures and cells were incubated for 5 hours. After the 5 hour exposure, each flask was rinsed with buffered saline, fresh medium containing BrDU was added, and cells were incubated for an additional 24 hours to allow 2 cycles of division. For the tests in the presence of metabolic activation, the same procedure was used with the exception that cells were incubated for 48 hours before treatment, 1.0 ml of S-9 activation mixture (from Aroclor 1254-induced Sprague-Dawley male rats) was added to the flasks, serum was omitted from the culture medium, the treatment period was 2 (instead of 5) hours, the incubation period was 28 (instead of 24 hours), test material concentrations were 1.0, 1.5 and 2.0 mg/ml) and dimethylnitrosamine (300 microliters/ml) was the positive control. DMSO vehicle and all concentrations of test material were tested in duplicate.
Colchicine (0.2 micrograms/ml) was added to the flasks 2 hr prior to harvest to produce mitotic arrest. Cells were removed and incubated for 20 min at 37 degrees C. Cells were then fixed, spread on slides and stained. The number of chromosomes and sister chromatid exchanges (SCEs) in 25 cells per culture were counted for each treatment group. Evaluation criteria Criteria for a positive response were not fully described. Statistics Data were analyzed using Box-Cox transformation (J Roy Stat Soc 26:211-252, 1964) and Levene's test for equality of variance. Homogeneous data were compared using analysis ofvariance (ANOVA) and pooled t-tests and non-homogenous data were compared using ANOVA for unequal variances, followed by separate t-tests. Results and discussions Test results Species/strain Chinese hamster Ovary (CHO) Metabolic activation with and without Test system strain/cell type: Chinese hamster Ovary (CHO) Genotoxicity negative Cytotoxicity yes Cytotoxic concentration: 2.0 mg/ml Vehicle controls valid yes N egative controls valid no data

Positive controls valid yes Additional information on results There was no effect of treatment on the incidence of sister chromatid exchanges (SCEs) in the absence of metabolic activation. In the presence of metabolic activation, a significant increase in SCEs was seen in one culture at 1.5 mg/ml (0.77 +/- 0.24 vs. 0.49 +/- 0.14 in DMSO control). This effect was not dose-related. There was no mitotic inhibition in the absence of S-9, and only the high dose (2 mg/ml) caused mitotic inhibition in the presence of S-9. The test was valid, as the positive controls induced significant increases in the frequency of SCEs.

Remark

s Details on test system and conditions Standard test: Test tubes containing 2 ml of soft agar, bacteria (0.1 ml of > = 10E8 S. typhimurium TA98, TA100, TA1535, or TA1537), test chemical (0.1 ml of test solution, p ositive control, or aqua dest. solvent) and either buffer or S-9 mix from Aroclor 1254-induced, male, Sprague Dawley rats (0.5 ml) were prepared. After mixing, the samples were poured onto minimal glucose agar plates within 30 seconds.
Preincubation test: Test tubes containing bacteria (0.1 ml of > = 10E8 S. typhimurium TA98, TA100, TA1535, or TA1537), test chemical (0.1 ml of test solution, p ositive control, or aqua dest. solvent) and either buffer or S-9 mix from Aroclor 1254-induced, male, Sprague Dawley rats (0.5 ml) were incubated at 37 degrees C for 20 minutes. Supplemented top agar (2 ml) was then added. After mixing, the overlay was poured onto minimal glucose agar plates. Plates were incubated at 37 degrees C for 48 hours in the dark. All dose levels (including positive and negative controls) were assayed in triplicate. The method of colony counting was not specified. Positive controls were 5 micrograms N-methyl- N ’-nitro- N -nitroso-guanidine MNNG) for strains TA100 and TA1535, 10 micrograms 4-nitro-o- p henylenediamine for strain TA98, and 100 micrograms 9-aminoacridine chloride monohydrate (AACM) for strain TA 1537 (all in the absence of S-9), and 10 micrograms 2-aminoanthracene (AA) for all strains in the presence of S-9. All positive control chemicals were dissolved in DMSO. Evaluation criteria Evaluation Criteria: The test material was considered a mutagen if both the mean number of revertant colonies was at least 2 times higher than the mean of the negative (solvent) control and it induced a reproducible dose-response relationship over several concentrations. If the dose-response was not definitive, it was considered to be a presumptive mutagen. If the reversion rates were between 2 and 3 times that of negative controls, the results were considered equivocal or inconclusive.

Addition of S-9 to strain TA98 increased the control mutation frequency to 34. S-9 had no effect on the frequency of mutations in the other strains. Positive controls induced an average of from 152 revertants in TA1535 to 1690 revertants in TA100. The number of revertants induced by test material was not increased from that of control at any concentration. The average number of revertants in cultures treated with test material (in the absence or presence of S-9) ranged from 109-140 in TA100, 12-21 in TA1535, and 8-11 in TA1537. Similar to control TA98 cultures, the average number of revertants in TA98 cultures treated with test material in the presence of S-9 (33-36) were higher than in the absence of S-9 (19-24).
Preincubation test: The average number of revertant in the controls for strains TA98, TA100, TA1535, and TA1537 in the absence of S-9 were 24, 111, 17, and 8. Addition of S-9 to strains TA98 and TA1535 increased the control mutation frequency to 33 and 23, respectively. S-9 had nosubstantial effect on the frequency of mutations in the other strains. Positive controls induced an average of from 94 revertants in TA1537 to 1127 revertants in TA100. The number of revertants induced by test material was not increased from that of control at any concentration. The average number of revertants in cultures treated with test material (in the absence or p resence of S-9) ranged from 108-135 in TA100 and 7-11 in TA1537. Similar to control TA98 cultures, the average number of revertants in TA98 and TA1535 cultures treated with test material in the presence of S-9 (35-41 and 18-26, respectively) were higher than in the absence of S-9 (19-24 and 14-18, respectively).
The tests were valid, as positive controls induced at least a two-fold increase in frequency of mutations. Remarks on results including tables and figures

rat Strain Sprague-Dawley Sex male/female Details on test animals and environmental conditions Rats were acclimated for 7 days before treatment. Only those with body weights within 2 standard deviations of the mean for each sex were used for the chromosome aberration tests. For the first test, the males weighed between 300 and 325 g and the females weighed between 208 and 235 g. Male rats used for the second test weighed between 328 and 359 g. Animals were randomized into groups of 5/sex for the first test and 5 males for the second test. Food and water were provided ad libitum except during dosing. Administration / exposure Route of administration oral: gavage Vehicle(s) corn oil Details on exposure Test material was dissolved in corn oil on the morning of the test. Doses used in the definitive tests were verified by gravimetric analyses. Dilutions were prepared for a dosing volume of 10 ml/kg.Preliminary tests with 3 males/dose level (4 from 2560 to 5000 mg/kg) and 5 animals/sex/dose level (6 from 1638 to 5000 mg/kg) were conducted to determine the LD50 value. An additional group of 5 females was dosed at 1301 mg/kg. The LD50 values were calculated by probit analysis.
In the first test, groups of 5 animals/sex/test interval were dosed with test material by gavage at 25% (750 mg/kg for males, 450 mg/kg for females), 50% (1500 mg/kg for males and 900 mg/kg for females), and 80% (2400 mg/kg for males and 1500 mg/kg for females) of the LD50 values. An additional dose of 375 mg/kg (12.5% of LD50 value) was given to 5 males/ test interval (two of these rats were not within 2 standard deviations of the mean) due to high mortality at the high dose. Groups of 5/sex/interval were administered corn oil vehicle by gavage. The positive control cyclophosphamide (30 mg/kg) was administered i. p . to one group of 5 animals/sex.
In the second test, five males/test interval were given corn oil vehicle or test material at doses of 375, 600, 750, 1000 and 1500 mg/kg by gavage. An additional 5 males were given cyclophosphamide (30 mg/kg, i. p .). Duration of treatment / exposure up to 48 hours Frequency of treatment See details on exposure section. Post exposure period See details on expsure section. Doses / concentrations 450, 900, 1500 mg/kg (females); 750, 1500, 2400 mg/kg (males); 375, 600, 750, 1000, 1500 mg/kg (males) Basis other: gravimetrically determined N o. of animals per sex per dose five animals per sex per dose Control animals yes, concurrent vehicle Positive control(s) The positive control cyclophosphamide (30 mg/kg) was administered i. p . to one group of 5 animals/sex. Examinations Tissues and cell types examined When possible, 500 cells per animal were scored for the proportion of mitotic cells. When p ossible, 50 metaphase cells per animal were evaluated blindly for chromosome number, specific type of chromosome or chromatid-type aberrations, deletions and exchanges, gaps, endoreplicated chromosomes and polyploid cells were noted but were not included as statistically evaluated aberrations. Severely damaged cells (> = 10 breakage events) and p ulverized cells were recorded as severely damaged, but no attempt was made to classify the types of damage in these cells. Evaluation criteria The result was considered positive if there was a statistically significant and dose-related increase in the frequency of chromosome aberrations. The result was equivocal if one result was significantly different from control and there was no dose-response. The result wasnegative if none of the doses produced a significant increase. Statistics The LD50 values were calculated by probit analysis. Data were analyzed using the Fisher's Exact Test (one-tailed). A difference between treated and control cells was considered to be significant if p 0.05 (one-tailed). Any other information on materials and methods incl. tables

Animals treated with test material were terminated at preassigned time intervals of 12 hr, 24 hr or 48 hours for the first study, and 24 or 48 hours for the second study. Vehicle controls were terminated at 24 hours in the first study and at 24 and 48 hours in the second study. Positive control animals were killed at 24 hours in both studies. Colchicine (4 mg/kg) was injected i.p. 2-3 hours prior to euthanization. A femur was removed from each animal. Bone marrow cells were collected and fixed. Slides were prepared and chromosomes were stained with Giemsa.

When possible, 500 cells per animal were scored for the proportion of mitotic cells. When possible, 50 metaphase cells per animal were evaluated blindly for chromosome number, specific type of chromosome or chromatid-type aberrations, deletions and exchanges, gaps, endoreplicated chromosomes and polyploid cells were noted but were not included as statistically evaluated aberrations. Severely damaged cells (> = 10 breakage events) and pulverized cells were recorded as severely damaged, but no attempt was made to classify the types of damage in these cells.

Results and discussions Test results Sex male/female Genotoxicity negative Toxicity Vehicle controls valid yes N egative controls valid Positive controls valid yes Additional information on results The preliminary toxicity test indicated that 3200 to 500 mg/kg test material produced mortality in 1/3 male rats. Based on these results, 7 dose levels ranging from 1310 to 5000 mg/kg were tested in another study. All male and female rats dosed with 5000 mg/kg, 4/5 males dosed with 4000 mg/kg and 5/5 females dosed with 3200 mg/kg died. The LD50 value was 3016 mg/kg for males and 1823 mg/kg for females.
In the first test, a significant increase in aberrations was observed in male rats treated with 375 (6.8 vs. 1.2% in control) or 750 mg/kg test material for 48 hours (9.5%), excluding one high dose animal that had multiple fragments. The incidence of aberrations in male rats treated with 750 mg/kg test material was 23.3 % if this animal was included. N o significant increase in aberrations was noted in males treated with 1500 mg/kg at any interval, males treated with 375 or 750 mg/kg for 12 or 24 hours, or females treated with any dose for any time interval measured. The test was valid, as the positive control induced a significant increase inaberrations in both sexes with respect to control (25.2% in males and 24.2% in females).
A second test was performed to determine if the results seen in the first test were reproducible. The mean incidences of aberrations in treated male rats ranged from 0.8 to 1.6% among cells harvested 24 hours after dosing (vs. 1.2% in vehicle control) and from 0 to 1.2% for cells harvested at 48 hours (vs. 0.8% in vehicle control). N o significant or dose-related increases in aberrations were noted in treated rats. The positive control induced aberrations in 16.4% of cells, indicating that the test system was responsive to a clastogenic agent.
Since the positive results in males in the first test were not dose dependent and could not be confirmed in the second experiment the material was judged to be negative in the test. Genetic toxicity in vivo.002 UUID IUC5-d61de3a6-f75c-4270-930e-f023c9275477 Dossier UUID 0

They were acclimated for 5 to 6 days before dosing. Animals used for the definitive micronucleus test were randomized by weight and those outside a range of two standard deviations were not used. Administration / exposure Route of administration intraperitoneal Vehicle(s) Fresh suspensions oftest material in corn oil were made on the morning of the test and dilution concentrations were verified by gravimetric analysis. Details on exposure Mice (5/sex/group) were dosed with test material over a range of dose levels from 410 to 1000 mg/kg in a preliminary test to determine the optimal doses for use in the definite test. The ratio of polychromatic erythrocytes (PCE) to normochromatic erythrocytes ( N CE) was determined for the highest group in which at least 3 animals survived for 48 and 72 hours after dosing.
For the definitive test, the body weights for males ranged from 23.8 to 26.9 g, and for females from 20.6 g to 22.2 g. Three dose levels of approximately 25, 50 and 80 % of the LD50 value (200, 400 and 640 mg/kg), a vehicle control (10 ml/kg), or the positive control triethylenemelamine (TEM, 0.3 mg/kg) were given i. p . to groups of 5 mice/sex. An additional 3 animals/sex were dosed with 640 mg/kg. Bloodsamples were collected from tails 30, 48 and 72 hours after dosing of vehicle or test material. Positive control animals were sampled at 30 hours only. One or two blood smear slides were prepared per animal per sampling time. Slides were stained and read blindly. Micronuclei wereidentified as darkly-stained, spherical inclusions in p olychromatic erythrocytes (cells with pale-blue staining of the cytoplasm). N CE's did not stain blue. A minimum of 1000 PCE was examined per animal per sampling time (unless precluded by cytotoxicity). The PCE/ N CE ratio for approximately 1000 total cells was calculated. Slides of several of the high dose animals had low numbers of erythrocytes and reduced ratios of PCE/ N CE. The lowest 3/sex were eliminated, leaving 5/sex/dose group for evaluation.

Examinations Tissues and cell types examinedSee details and slide preparation section below. Details of tissue and slide preparation One or two blood smear slides were prepared per animal per sampling time. Slides were stained and read blindly. Micronuclei were identified as darkly-stained, spherical inclusions in p olychromatic erythrocytes (cells with pale-blue staining of the cytoplasm). N CE's did not stain blue. A minimum of 1000 PCE was examined per animal per sampling time (unless precluded by cytotoxicity). The PCE/ N CE ratio for approximately 1000 total cells was calculated. Slides of several of the high dose animals had low numbers of erythrocytes and reduced ratios of PCE/ N CE. The lowest 3/sex were eliminated, leaving 5/sex/dose group forevaluation. Evaluation criteria Data from males and females were analyzed separately and collectively. The result was considered positive if at least one significant increase ( p < = 0.01) above the control was observed with an indication of a dose-response. A test was considered inconclusive if a significant increase was noted at one dose and no dose-response relationship was apparent. A test was negative if there were no significant differences between control and treated animals at any dose. Statistics Data from treated groups were compared to those of the vehicle control using the Fisher's exact
test. Results and discussions Test results Sex male/female Genotoxicity negative Toxicity yes A pooled LD50 value of 806.4 mg/kg was calculated. Vehicle controls valid yes N egative controls valid no data

Positive controls valid yes Additional information on results All five males and three females dosed with 1000 mg/kg in the preliminary study died within 48 hours of dosing. A dose of 800 mg/kg was lethal to 4/5 males and 2/5 females. N o animals dosed with 512 mg/kg or less died. Using the moving average method of Thompson and Weil, a p ooled LD50 value of 806.4 mg/kg was calculated. Doses chosen for use in the study were 25, 50 and 80% of this value.
There were no significant decreases in the PCE/ N CE ratio in females treated with any dose at any time. This ratio was reduced in samples taken at 72 hours from males treated with 640 mg/kg (83.8% of control), indicating a moderate degree of bone marrow cytotoxicity. This decrease was not sufficient to preclude evaluation of micronuclei.
Analysis of variance testing indicated that there were no sex-related differences in the incidences of micronuclei in males and females treated for 72 hours; therefore, values for 72 hours were pooled for subsequent analyses. Values at 30 and 48 hours were not pooled because there were sex-related differences. Remarks on results including tables and figuresAs shown in the table below, no statistically significant increases in micronuclei were noted between controls and animals treated with test material at any time period.

rat Strain Sprague-Dawley Sex male/female Details on test animals and environmental conditions Animals: CD (Crl: CD(SD)IGS BR) rats were obtained from Charles River Laboratories, Inc. They were acclimated to the laboratory at least one week prior to treatment, and were approximately 8 weeks old at the beginning of the study. Animals were housed one per cage ( p rebreeding) or two per cage (one per sex during breeding) in stainless steel cages. Dams were housed one per cage (with litter) in plastic cages with ground corn cob nesting material from approximately gestation Day 19 through lactation, under a 12 hour light/dark photocycle. Room humidity and temperature were maintained at 40-70% and 22 +/- 1 degrees C. Room air was exchanged approximately 12-15 times/hour. Animals were allowed free access to food and municipal water. There were no contaminants in the feed or water that would interfere with the study. Administration / exposure Route of administration oral: feed Vehicle unchanged (no vehicle) Details on exposure Diet preparation: Diets were prepared by serially diluting a concentrated test material-fee mixture ( p re-mix) with ground feed. Pre-mixes were prepared periodically throughout the study based on stability data. Diets were prepared weekly for two weeks prior to breeding. Concentrations of material in the diets were calculated from body weights and feed consumption data. To avoid potential overdosing during the breeding period, co-housed animals were provided with the female diet, which was of lower concentration. Following breeding. Themale diet was prepared weekly until necropsy. During gestation and lactation, female were p rovided with the same concentrations as given during breeding. Representative samples from the test diets were analyzed at least once to ensure homogeneous distribution of test material at the lowest and highest concentrations. Details on mating procedure During breeding, each female was caged with a male from the same group until pregnancy occurred ( p resence of sperm in vaginal lavage sample evaluated daily or presence of a copulatory plug) or two weeks had elapsed. The day on which pregnancy was detected was considered lactation Day 0. If mating did not occur after two weeks, the animals were separated without further opportunity for mating. Analytical verification of doses or concentrations
yes Details on analytical verification of doses or concentrations All test diets from the first mix were analyzed prior to dosing using gas chromatography-mass spectrometry (GC-MS), and an internal standard. Reference samples (one/dose/mix) were retained and stored in sealed vials.
Analyses of all test diets from the first mix of the main study revealed mean concentrations ranging form 92.5 to 104% of targeted concentrations. Analyses of the low dose female and high dose male diets indicated that the diets were homogeneous. Analyses confirmed that the 10% p remix was stable fo r 14 days and that the test diets were stable for 8 days at concentrations ranging from 0.120 to 0.359%, which encompass the range of dietary concentrations used in the study. Duration of treatment / exposure Females were dosed daily for two weeks prior to breeding, through breeding (two weeks), gestation (three weeks), and through postpartum Day 4. The males were dosed for two weeks p rior to breeding and continuing through breeding (two weeks) up until necropsy.
Exposure period was 53 days. Duration of test: to post- p artum Day 5 Frequency of treatment Continuous (feed) Details on study schedule Study conduct: Groups of 12 male and 12 female CD rats randomly assigned to four treatment groups and were fed diets supplying concentrations of 0 (control), 100, 300 and 1000 mg/kg/day. Females were dosed daily for two weeks prior to breeding, through breeding (two weeks), gestation (three weeks), and through postpartum Day 4. The males were dosed for two weeks prior to breeding and continuing through breeding (two weeks) up until necropsy. Females that delivered were necropsied on post- p artum Day 5. Pups were euthanized on p ostnatal Day 4.

yes, p lain dietFurther details on study design A limit dose of 1000 mg/kg/day was selected as the high dose level based on data obtained in a p reliminary range-finding study. The authors reported no-observable-effect-levels ( N OELs) of 300 mg/kg for general toxicity and 1000 mg/kg for reproductive and neurological effects Examinations Parental animals: Observations and examinations Cage-side examinations for skin, fur, mucous membranes, respiration, nervous system function (including tremors and convulsions), animal behavior, moribundity, mortality, availability of feed and water, and litter observations were conducted twice daily. Females were observed for signs of parturition on or about gestation Day 20. Females that delivered received clinical examinations on lactation Days 0, 1 and 4. Females that failed to mate or deliver were subjected to hand-held evaluations weekly.
Detailed clinical observations were conducted on all rats before exposure and weekly throughout the study. Mated females underwent these examinations on gestation Day 0, 7, 14, and 20, and on lactation Day 3. The examination included cage-side, hand-held and open-filed observations.
All rats were weighed prior to exposure, twice during the first week of the study and once during the second week. Male body weights continued to be recorded weekly throughout the study. Presumed pregnant females were weighed on gestation Day 0, 7, 14 and 20. Females that delivered litters were weighed on lactation Days 1 and 4. Females that failed to mate or deliver a litter were not weighed during the gestation or lactation phases.
Feed consumption was determined prior to exposure on twice during the first week of exposure. It was then determined once a week during the re-breeding phase. It was not determined during breeding. After breeding, it was determined once a week for males and on gestation Days 0, 7, 14, and 20 for mated females. After parturition, feed consumption was measured on lactation Days 1 and 4. Feed consumption was not recorded for females that failed to mate or deliver a litter.
Functional tests (sensory evaluation, rectal temperature, grip performance and motor activity) were conducted prior to exposure and during the last week of the treatment period (lactation Day 4 for females).
Females were observed for signs of parturition beginning on or about gestation Day 20. The day of delivery was recorded as lactation Day 0.
A timed urine volume (overnight, 16 hours) was obtained from all male rats (nonfasted) during the week prior to scheduled necropsy. Urine was analyzed for colour, appearance, specific gravity, volume, p H, bilirubin, glucose, p roteins, ketones, blood and urobilinogen. Urine collected by manual compression of the bladder was pooled from each group and analyzed microscopically for microsediment.
On the day prior to the scheduled necropsy, all males and females in each group were fasted overnight. At necropsy, the animals were anesthetized with CO2 and blood was collected from the orbital sinus. Blood samples were not collected form females that failed to deliver. Bloodwas analyzed for hematocrit, hemoglobin concentration, red blood cell count, total and differential which blood cell counts, p latelet count, red blood cell indices (mean corpuscular hemoglobin, mean corpuscular volume and mean corpuscular hemoglobin concentration), and p rothrombin time. Serum was analyzed for alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, albumin, cholesterol, creatinine, sodium, p otassium, p hosphate, chloride, calcium, glucose, total bilirubin, total protein and urea nitrogen.
Males were terminated and necropsied on test Day 34. Females that delivered were terminated and necropsied on post- p artum Day 5. Females that did not deliver were terminated and necropsied at least 24 days after the last day of the mating period. Pups were euthanized on p ostnatal Day 4. Estrous cyclicity (Parental animals) Mated females underwent these examinations on gestation Day 0, 7, 14, and 20, and on lactation Day 3. The examination included cage-side, hand-held and open-filed observations. Litter observations All litters were examined as soon as possible after delivery. The litter size on lactation Day 0, numbers of live and dead pups on postpartum Days 0, 1 and 4, clinical observations, and sex and weight of each pup on lactation Days 1 and 4 were recorded. Any pups dead or euthanized in moribund condition were examined grossly for external and visceral defects. Postmortem examinations (Parental animals) Post-mortem examinations included a gross necropsy of all adults (which included a gross examination of the brain, p ituitary and eyes), with collection of organ weights (testes, epididymides, seminal vesicles with coagulating gland, p rostate, ovaries, liver, kidneys, adrenals, thymus, spleen, brain, thyroid/ p arathyroid, and heart) and extensive histopathologic examination of tissues (adrenals, aorta, auditory sebaceous glands, bone (including joint), bone marrow, brain, cecum, cervix, coagulating glands, colon, cranial nerve, duodenum, epididymides, esophagus, eyes, gross lesions, heart, ileum, j ejunum, kidneys, lacrimal/Harderian glands, larynx, liver, lungs, mammary gland, mediastinal lymph node and tissues, mesenteric lymph node and tissues, nasal tissues/ p harynx, oral tissues, ovaries, oviducts, p ancreas, p arathyroid glands, p eripheral nerve, p ituitary, p rostate, rectum, salivary glands, seminal vesicles, skeletal muscle, skin and subcutis, spinal cord, spleen, stomach, testes, thymus, thyroid gland, tongue, trachea, urinary bladder, uterus and vagina) from control and high dose animals. The histopathological examination of the testes included a qualitative assessment of states of spermatogenesis. The uteri of all females were examined and the number of implantation sites recorded. The uteri of females that did not deliver were stained with a 10% solution of sodium sulfide to verify pregnancy status. Statistics Statistical analyses: Parental body weights, gestation and lactation body weight gains, litter mean body weights, feed consumption, urine volume, urine specific gravity, coagulation, clinical chemistry data, hematological data and organ weights were first evaluated by Bartlett's test for homogeneity. Parametric and nonparametric data were then analyzed by the appropriate analysis of variance (ANOVA). If the ANOVA was significant at alpha = 0.05, a Dunnett's test (alpha = 0.05) or the Wilcoxon Rank Sum test with Bonferroni's correction was performed. Feed consumption data were excluded if the feed was spilled or scratched.
Gestation length, average time to mating, and litter size were analyzed using a non- p arametricANOVA. If the ANOVA was significant, the Wilcoxon Rank Sum test with Bonferroni's correction was performed. Statistical outliers (alpha = 0.02) were identified and excluded from the analysis only for documented, scientifically sound reasons. Mating, conception, fertility and gestation indices were analyzed by the Fisher exact probability test, with Bonferroni's correction. The neonatal sex ratio was analyzed using the binomial distribution test. Genders of p ups found dead were included in the ratio. Survival indices, p ost-implantation loss and other neonatal incidence data were analyzed using the litter as the experimental unit by the censored Wilcoxon test (alpha = 0.05). Females failing to deliver a litter were excluded from analyses of gestation and lactation body weight, feed consumption and organ weights. Detailed clinical observation and sensory evaluation scores were analyzed using a z-test of proportions (at alpha = 0.05). Rectal temperature and grip performance were analyzed by an analysis of covariance. Motor activity was analyzed by a repeated measure design. Results and discussions Effect levels

All animals survived to termination. There was a slight treatment-related decrease in body weights of males and females given 1000 mg/kg/day. Decreased maternal body weights persisted throughout the gestation and lactation phases of the study. Decreased feed consumption was noted in high dose males and females during the p rebreeding period and in high dose females during gestation.
Females given 1000 mg/kg/day had treatment-related increases in serum ALT and ALP activities, along with increases in relative liver weight. These effects corresponded with treatment-related histopathologic changes in the liver that consisted of very slight panlobular hepatocyte hypertrophy. Males given 1000 mg/kg/day had treatment-related increases in relative liver weight, which corresponded with the histological alteration of very slight p eriportal hepatocyte hypertrophy. At 1000 mg/kg/day, other findings of lesser significance included slightly increased blood urea nitrogen and decreased absolute thymus weights in females, and decreased urine pH and increased relative kidney weights in males. Additional histopathologic findings of minor toxicological significance at 1000 mg/kg/day included very slight diffuse acinar hypertrophy of the submandibular salivary gland in males, and very slight atrophy of the mesenteric adipose tissue in females.
There were no adverse effects of DGHE on neurological or reproductive function (time to mating, female or male mating index, female or male conception index, female or male fertility index, gestation index, gestation survival index, p ost-implantation loss), or prenatal/early neonatal growth,survival, or external condition of the offspring. There were no adverse gross or histopathologic findings in the reproductive organs of high dose males or females.

Based on these results, the no-observed-adverse-effect level ( N OAEL) for general toxicity was 300 mg/kg/day. The NOAEL for reproductive and neurological effects was 1000 mg/kg/day, the highest dose level tested. Observations: offspring Viability (offspring)

Control animals other: both negative (water) and positive (50 and 250 mg/kg ethylene glycol monomethyl ether) Further details on study design Female rats were mated with males of the same strain when they were approximately 11-13 weeks of age. The first day spermatozoa were detected in vaginal smears was counted as Day 1 of gestation. Ten gestating animals per group were dosed with deionized water, 250 mg/kg triethylene glycol monobutyl ether (TGBE), 1000 mg/kg TGBE, 50 mg/kg ethylene glycol monomethyl ether (EGME), or 250 mg/kg EGME. Dose levels of TGBE were selected based on the results of a previous range finding study. EGME was administered at levels known to p roduce toxicity in the assay. All animals were dosed by gavage from Days 7-16 (inclusive) of gestation with 1 ml of dosing solution per 100 g body weight using a 5ml glass syringe and stainless steel (16 gauge cannula). Dosing solutions were prepared immediately prior to dosing and stored in a refrigerator until use. The volume given to each animal was adjusted daily according to body weight. Examinations Maternal examinations Rats were observed each day for clinical condition and signs of illness. Body weights were recorded on Days 1, 7 through 17, 19, and 22 of gestation and on Day 5 p ost partum.
Maternal body weight gains were measured during treatment and pregnancy. Ovaries and uterine content The uteri of females which failed to litter were grossly examined for implantation sites on or shortly after Day 25 of gestation to ascertain if the animals had been pregnant. Fetal examinations Litters were weighed and sexed on Days 1 (within 24 hours of birth) and 5 p ost partum. Dead p ups were not weighed. Mortality on Day 1 and Day 5 p ost partum was recorded.
Animals which littered and their offspring were killed and discarded without postmortemexamination after Day 5 p ost partum. Statistics Litters produced/number pregnant, number of viable litters on Days 1 and 5, total number of live pups/litter, total number of dead pups/litter, mean total litter size (live and dead pups), survival percentage, number of dead pups per group, mean pup weight (Days 1 and 5), mean p up weight gain and mean % weight gain/litter datafrom treated and control animals were compared using the Student's t-test.

Details on maternal toxic effects Maternal Data: Dams dosed with either dose of TGBE appeared normal throughout the study and gained a similar amount of weight as negative controls. Administration of 50 or 250 mg/kg EGME was associated with piloerection. Four animals in the 250 mg/kg EGME group had slight vaginal bleeding between Days 17 and 19 of gestation. Details on embryotoxic / teratogenic effects Litter Data: The pregnancy rate was high with 9/10 p regnancies in the negative control group, and 10/10 p regnancies in the groups dosed with TGBE. N o litters were produced in either EGME group (although implantation sites were present in all animals). There were no effects on any litter parameter measured in rats treated with either dose of TGBE. Remarks on results including tables and figures

At the dose levels tested (250 or 1000 mg/kg/day), TGBE was not embryotoxic or teratogenic (in contrast to EGME).

Triethylene glycol monomethyl ether and triethylene glycol monoethyl ether also were not teratogenic at 1000 mg/kg.
