- Remarks:
- with and without activation
- Details on test system and experimental conditions:
- After 0.1 mL of the test item solution, vehicle or the positive control item solutions, 0.5 mL of 0.1 M sodium phosphate buffer or S9 mix and 0.1 mL of the bacterial culture were added to a test tube, the mixture was shaken at 37°C +/- 0.5°C for 20 minutes. Two milliliters of the soft agar were then added to each tube and the mixture was poured onto a minimal glucose agar plate. The number of revertant colonies was counted after incubation at 37°C +/- 0.5°C after 48 h.
- Evaluation criteria:
- The test item was judged to be positive when the number of revertant colonies increased to twice or more than that in the negative control and when the responses were dose-related and/or reproducible.

Applicant's summary and conclusion
- Conclusions:
- It was concluded that the substance had no ability to induce mutations under the present test conditions.
- Executive summary:
The mutagenicity of the test item was judged to be negative because the number of revertant colonies in the test item treatment groups was less than twice that in the negative control for all tester strains regardless of the presence or absence of S9 mix.
