Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
As part of a study of the mutagenic potential of 300 chemicals, ethanol was evaluated in a bacterial reverse mutation (Ames) assay at a plate concentration of up to 10mg/plate in the presence of metabolic activation. There was no evidence of mutagenicity in either of the two strains examined (TA98, TA100). . It should be noted that only two of the normal four bacterial strains were evaluated, so the study cannot be regarded as complete or definitive.
Ethyl Alcohol is both reagents used in the manufacture, as well as decomposition products of xanthates. Therefore, the health effects of Ethyl Alcohol need to be considered in the assessment of potassium ethyl xanthate. - Executive summary:
