Genetic toxicity: in vitro
Administrative data
- Endpoint:
- in vitro gene mutation study in bacteria
- Remarks:
- Type of genotoxicity: gene mutation
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- With this test it is not possible to identify certain oxidising mutagens, cross-linking agents and hydrazines. Such substances may be detected by E.coli WP2 strains or S. typhimurium TA102 which have an AT base pair at the primary reversion site in stead of GC base pairs which the strains tested in this study have. No independent repeat was performed to confirm the negative result.

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
It was concluded that the test substance did not reveal mutagenic activity in the Salmonella/microsome mutagenicity test. - Executive summary:
The mutagnic activity. Of the test subsatnce was examined in the Salmonella/micosome mutagenicity test, using a set of five histidine
requiring mutants of S. typhimurium (TA 1535, TA 1537, TA1538, TA 98 and TA 100) and liver homogenate of Aroclor-induced rats.
Incorporation of the test product with the bacteria up to non-inhibitory levels (i.e. 1.0 mg per plate) did not increase the numbers of his revertants in any of the five tester strains either in the presence or in the absence of the liver microsome activation system.
It was concluded that the present results did not reveal any mutagenic activity of the test sample in the Salmonella/microsome mutagenicity test.
