NUMBER OF REPLICATIONS: Three
DETERMINATION OF CYTOTOXICITY
- Method: A reduction in the number of spontaneously occurring colonies and visible thinning of the bacterial lawn were used as toxicity indicators.
Thinning of the bacterial lawn was evaluated microscopically. - Evaluation criteria:
- The test substance was considered positive if
(a) at least a 2-fold increase in the mean number of revertants per plate of at least one of the tester strains over the mean number of revertants per plate of the appropriate vehicle control at complete bacterial background lawn
(b) a dose-related increase in the mean number of revertants per plate of at least one of the tester strains over the mean number of revertants per plate of the appropriate vehicle control in at least two to three concentrations of the test compound at complete bacterial background lawn.
If the test substance does not achieve either of the above criteria, it is considered to show no evidence of mutagenic activity in this system - Statistics:
- Not reported (According to the OECD guideline 471, a statistical analysis of the data was not mandatory).

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative with metabolic activation
negative without metabolic activation
Under the test conditions, the test substance is not mutagenic in the absence and presence of exogenous metabolic activation in the standard plate incorporation and the preincubation tests. - Executive summary:
A study was conducted to determine the mutagenic potential of test substance according to OECD Guideline 471, EPA OPPTS 870.5100, EU method B.13/14.and Japanese Substance Control Law (JSCL) Test Guideline III.1 in compliance with GLP.
Strains TA 100, TA 1535, TA 1537 and TA 98 of Salmonella typhimurium and Escherichia coli WP2uvrA were used in the mutagenicity assay.
Two independent mutagenicity studies were conducted, one as the standard plate test with the plate incorporation method and the other as a modified preincubation test (Prival test). The studies were performed in the absence and in the presence of a metabolizing system derived from a rat liver homogenate or a hamster liver homogenate. For both studies, the compound was dissolved in deionized water, and each bacterial strain was exposed to 5 dose levels.
Doses for both studies ranged from 50 to 5000µg/plate.
Control plates without mutagen showed that the number of spontaneous revertant colonies was within the laboratory's historical control range. All the positive control compounds gave the expected increase in the number of revertant colonies.
In the preincubation test the number of revertant colonies of the solvent controls in the presence of
S9-mix and the number of revertants colonies of the positive controls in the absence of S9-mix
with the strain WP2uvrA were out of the historical control data range, but the criteria for the
negative/positive responses were fulfilled.
Toxicity: In the mutagenicity experiments toxicity was not observed either with or without metabolic activation.
Plate incorporation test: Both in the absence and in the presence of rat liver(10 % (v/v)) metabolic activation system the test substance did not result in relevant increases in the number of revertants in any of the bacterial strains.
In the absence and in the presence of hamster liver S9-mix (30 % (v/v)) using the preincubation method according to Prival, test substance did not result in relevant increases in the number of revertant colonies with any of the tester strains.
Under the test conditions, the test substance is not mutagenic in the absence and presence of exogenous metabolic activation in the standard plate incorporation and the preincubation tests.
