Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative With and without metabolic activation
The test material did not induce more than twice increase in the revertant colony count compared with the count of the negative control in any of the tester strains, either with or without metabolic activation.
Therefore, it was not considered that the test material is mutagenic.
