Possible 

2-Butoxyethanol [synonym: ethylene glycol monobutyl ether (EGBE)] is a component of this product. EGBE has no 

tendency to accumulate in humans or animals (Clayton & Clayton, 1994 ). Little is known about the potential long-term or 

delayed effects of low-level chronic EGBE exposure. 

In mice, treatment with doses of 500 or 1,000 mg/kg/day for 4 days induced atrophy of the thymus and lymphocytopenia, 

indicative of potential depression of the immune system. Hemolytic anemia was also produced (Grant et al, 1985). 

9/12/2013. c ] ( {i 519 
1~----~1~c~·~-~--------------------------~ 11 . Toxicological information 

Anemia was also produced in rats. 

Reproductive studies in laboratory animals have produced mixed results. 

Chronic inhalation has produced tumors in laboratory animals [National Toxicology Program (2000) Report NTP TR 484 

and NIH Publication No. 00-3974]. 

In vitro mutagenicity has been demonstrated in human lymphocytes [Vallalobos-Pietnini, R. et al (1989) Revista 

lnternacionial de Contaminaci on Ambiental 5: 41-48]. 2-Butoxyethanol expressed positive in vitro mutagenic results in 

Salmonella typhimurium TA 97a, with and without metabolic activation [Hoflack, J.C. et al (1995) Mutation Research 341: 

281-287]. 

Chronic ingestion and inhalation has produced fetotoxicity and postnatal developmental toxicity in laboratory animals 

[Heindel, J.J. et al (1990) Fundmental Applied Toxicology 15: No.4 683-696 and Tyl, R. et al (1984) Environmental Health 

Persp. 57: 47-68]. 

ACGIH has classified 2-butoxyethanol as an animal carcinogen with unknown relevance to humans. 

4) Naphthalene 

This product contains naphthalene. A National Toxicology Program (NTP) report concluded there is clear evidence to 

support carcinogenicity of naphthalene in male and female rats. These observations were based on 2-year inhalation 

studies in which the test animals were exposed to 10, 30, and 60 ppm naphthalene. In male and female rats, exposure to 

naphthalene caused significant increases in the incidence of nonneoplastic lesions of the nose (NTP TR-500). The 

relevance of the rodent findings to humans is questionable. 

Naphthalene has caused hemolytic anemia, jaundice, cataracts (Shopp et al, 1984), allergic reactions (Tsyrkunov & 

Yakovleva, 1985), possible neurotoxicity (Riala et al, 1984), and aplastic anemia (Harden & Baetjer, 1978) in humans. 

Increased lung aveolar adenomas were seen in mice exposed to 30 ppm naphthalene for 6hrs/day for 6 months (ACGIH, 

1992). 

Naphthalene crosses the placenta leading to methemoglobinemia (decreased ability for the blood to carry oxygen), and/or 

hemolytic anemia, conditions considered especially dangerous to the unborn (Reprotext). Liver and kidney damage has 

also been seen with exposure to naphthalene (Reprotext). 

Peripheral lens opacities occurred in 8 of 21 workers exposed to high levels of naphthalene fumes or vapors for 5 years, 

but cataracts have not been reported in other occupational studies. (Hathaway et al, 1991). 

The International Agency for Research on Cancer (IARC) evaluated naphthalene and concluded that there was sufficient 

evidence for carcinogenicity in experimental animals, but inadequate evidence that it causes cancer in exposed humans. 

Accordingly, IARC classified naphthalene as a possible human carcinogen (Group 28).
