Applicant's summary and conclusion
- Conclusions:
- Interpretation of results: negative. The test substance is not mutagenic both in the presence and absence of metabolic activation.
- Executive summary:
A mutagenicity study was performed on the test substance using S. typhimurium, and E. coli both in the presence and absence of metabolic activation. Concentrations of 3, 10, 33, 100, and 333 ug/plate were tested in triplicate. Precipitation was obersved at the 333 ug/plate concentration. A negative response was observed in all replicates at all concentrations, and no evidence of cytotoxicity was observed. Results for negative and positive controls were within historical norms. The test substance is not mutagenic.
