One oral study of the related compound isononyl benzoate resulted in a slight decrease in mean pup weight and conse- quently in litter weight in high-dose females at birth and on day 4 postpartum. The NOAEL was 1000 mg/kg/d. In Ames tests, methyl benzoate, ethyl benzoate, and C12-15 alkyl benzoate were not genotoxic. Isononyl benzoate adminis- tered orally at 2000 mg/kg to rats did not induce micronuclei in the polychromatic erythrocytes. Ethylhexyl benzoate was not an ocular irritant to humans in a sunscreen at 3.5%. 362S International Journal of Toxicology 31(Supplement 3)","endpoint":"oral toxicity","ingredient":"Alkyl Benzoates","loael_value":"","noael_unit":"mg/kg/d","noael_value":"1000","page":21,"route":"oral","species":"rat","study_id":"PRS578_noael_008"}
