Results and discussion
Test results
- Species / strain:
- S. typhimurium TA 1535, TA 1537, TA 98 and TA 100
- Metabolic activation:
- with and without
- Genotoxicity:
- negative
- Cytotoxicity / choice of top concentrations:
- no cytotoxicity, but tested up to precipitating concentrations
- Vehicle controls validity:
- valid
- Untreated negative controls validity:
- valid
- Positive controls validity:
- valid
- Additional information on results:
- No precitation of the test sub stance was found.
Occasionally, a slight decrease in the number of revertants was observed in the standard plate test with S-9 mix at 5,000 ug/ plate . In the preincubation assay bacteriotoxicity was found depending on the strain and test conditions_at doses > 2,500 ug / plate - Remarks on result:
- other: all strains/cell types tested
- Remarks:
- Migrated from field 'Test system'.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
According to the result's of the present study, the substance is not mutagenic in the Ames test and in the Escherichia coli - reverse mutation assay under the experimental condition chosen.
