NUMBER OF REPLICATIONS: Three
NUMBER OF CELLS EVALUATED: 3.2 to 8.2 x 10e8 cells per plate
PLATING ALIQUOT: 200 µL - Evaluation criteria:
- For the test substance to be evaluated positive, it must cause a dose-related increase in the mean revertants per plate of at least one tester strain over a minimum of two increasing concentrations of test substance as specified below:
Strains TA1535 and TA1537:
Data sets were judged positive if the increase in mean revertants at the peak of the dose response was equal to or greater than 3.0-times the mean vehicle control value.
Strains TA98, TA100 and WP2 uvrA:
Data sets were judged positive if the increase in mean revertants at the peak of the dose response was equal to or greater than 2.0-times the mean vehicle control value.
An equivocal response is a biologically relevant increase in a revertant count that partially meets the criteria for evaluation as positive. This could be a dose-responsive increase that does not achieve the respective threshold cited above or a non-dose responsive increase that is equal to or greater than the respective threshold cited. A response was evaluated as negative if it was neither positive nor equivocal. - Statistics:
- For each replicate plating, the mean and standard deviation of the number of revertants per plate were calculated.

- Additional information on results:
- TEST-SPECIFIC CONFOUNDING FACTORS
- Precipitation: Neither precipitate nor toxicity was observed at a maximum dose of 5000 μg per plate
- Other confounding effects: No contaminant colonies were observed on the sterility plates for the vehicle control, the test substance dilutions or the S9 and sham mixtures.
RANGE-FINDING/SCREENING STUDIES: A preliminary toxicity assay was conducted at dose levels of 6.67, 10.0, 33.3, 66.7, 100, 333, 667, 1000, 3333 and 5000 μg per plate in propylene glycol. The maximum dose of 5000 μg per plate was achieved using a concentration of 25.0 mg/mL and a 200 μL plating aliquot. Neither precipitate nor toxicity was observed.
Applicant's summary and conclusion
- Conclusions:
- Under the conditions of this study, test substance was negative for the ability to induce reverse mutations at selected loci of several strains of Salmonella typhimurium and at the tryptophan locus of Escherichia coli strain WP2 uvrA in the presence and absence of an exogenous metabolic activation system.
- Executive summary:
The test substance was tested to evaluate its mutagenic potential by measuring its ability to induce reverse mutations at selected loci of several strains of Salmonella typhimurium and at the tryptophan locus of Escherichia coli strain WP2 uvrA in the presence and absence of an exogenous metabolic activation system in accordance with OECD Guideline 471. Propylene glycol was used as the vehicle.
In the preliminary toxicity assay, the dose levels tested were 6.67, 10.0, 33.3, 66.7, 100, 333, 667, 1000, 3333 and 5000 μg per plate. Neither precipitate nor toxicity was observed. Based upon these results, the maximum dose tested in the mutagenicity assay was 5000 μg per plate.
In the mutagenicity assay, the dose levels tested were 100, 333, 1000, 3333 and 5000 μg per plate. Neither precipitate nor toxicity was observed. No positive mutagenic responses were observed with any of the tester strains in either the presence or absence of S9 activation. These results indicate test substance was negative for the ability to induce reverse mutations at selected loci of several strains of Salmonella typhimurium and at the tryptophan locus of Escherichia coli strain WP2 uvrA in the presence and absence of an exogenous metabolic activation system.
