 Health Summary: Absorption is nil through the skin as the neat material and 

moderate through the skin when in solution based on physical/chemical properties. Expect 

moderate absorption through the lungs and GI tract, based on analogs. Based on the submitted 

acute oral study, there is concern for neurotoxicity. There is concern for dermal and uncertain 

concern for respiratory sensitization, based on (A submitted dermal sensitization 

study on the same compound was negative; however, the highest concentration tested was 25%.) 

There is concern for photosensitization based on the and concern for 

mutagenicity for the because are positive in other assays (PMN 

compound was negative in Salmonella). 

 Test Data: Submitted with 

Negative in Salmonella with and without activation;

Not a dermal sensitizer in the mouse local lymph node assay at 5, 10, and 25% concentration;

Acute (single dose) oral study in rats, 2000 mg/kg: no deaths; apathy, prone position, reduced

Ecotoxicity Test Data Results for P-11-0424: 

Two acute ecotoxicity studies were conducted on this PMN (P-11-0424) in

(sponsor) with aquatic invertebrates and aquatic plants. The PMN is yellowish solid at room 

temperature with a purity of >97%, measured water solubility 4 g/L, a measured vapor pressure 

of 1.5E -5 mmHg at 25°C, and a measured log Kow of 3.6. The testing laboratory measured the 

PMN during the ecotoxicity studies using a HPLC-UV/Vis (limit of quantification (LOQ) = 0.03 

mg/L and 0.075 mg/L for aquatic invertebrates and aquatic plants, respectively). The testing 

laboratory performed toxicity tests for the aquatic invertebrate and aquatic plant tests according 

to OECD guidelines 202 and 201, respectively. A certificate of analysis was provided for this 

PMN. The studies complied with OECD guidelines for: 1) O2, pH, temperature, water hardness 

values and other water quality parameters; 2) species, age, number of organisms per replicate, 

and biomass loading rates; and, 3) replicate and overall variability.

In a 48-hour immobilization test, water fleas (Daphnia magna) (5 daphnia/replicate x 4 

replicates) were exposed to nominal concentrations of 0.043, 0.094, 0.21, 0.45, and 1.0 mg/L 

(and a control) of the PMN under static conditions. The mean-measured concentrations were 

0.013, 0.035, 0.054, 0.15, and 0.37 mg/L (and a control). Other than one immobile D. magna in 

the highest test concentration (statistically and biologically not significant), no effects were seen 

at all tested concentrations. Over the course of the study, water temperature ranged from 

20-21°C; pH ranged from 7. – 7.7; O2 levels concentrations ranged from 8.3-8.7 mg/L and water 

hardness was 250 mg CaCO3/L (in the dilution water). The measured 48-hour EC50 

(immobilization) for D. magna is > 0.043 mg/L. The measured NOEC for immobilization is ≥

0.043 mg/L. 

In a 72-hour limit test for algal growth rate and yield, an initial cell concentration of 0.5E+4 

cells/ml (6 replicates/control and 3 replicates/test concentration) of green algae 

(Pseudokirchneriella subcapitata) were exposed to nominal concentrations of 0.010, 0.032, 0.10, 

and 1 mg/l (and a control) of the PMN under static conditions. The test concentrations resulted 

from dilutions from a 10 mg/L water accommodated fraction stock solution. The mean 

measured concentrations were: control, < LOQ, < LOQ, < LOQ, 0.06, and 0.21 mg/L. The test 

occurred with continuous light (640 lux) and continuous agitation. The temperature was 23°C. 

The pH ranged from 8.1 – 9.0. The water hardness was 24 mg CaCO3/L (in the dilution water). 

Cell growth was measured spectrophotometrically. The measured 72-hour algal EC50 for 

growth rate and yield are > 0.21 mg/L. The measured 72-hour algal NOEC for growth rate and 

yield are ≥ 0.21 mg/L.

The two acute ecotoxicity studies are considered valid. Adverse effects were not observed in the 

EPA SANITIZED Page 6 of 37
daphnid and algal aquatic toxicity tests. There are no effects at saturation for aquatic 

invertebrates and aquatic plants for P-11-0424. Since only ecotoxicity tests for aquatic 

invertebrates and aquatic plants were submitted for P-11-0424, the chronic and acute concern 

concentrations for P-11-0424 will be based on the ECOSAR (v. 1.00a) predictions for fish. As a 

result, the chronic and acute concern concentrations are 26 ppb and 660 ppb, respectively.
