- OTHER: In the first experiment 5% (v/v) S9-mix was used and in the second experiment 10% (v/v) S9-mix was used. - Evaluation criteria:
- Acceptability of the assay:
A Salmonella typhimurium reverse mutation assay and/or Escherichia coli reverse mutation assay is considered acceptable if it meets the following criteria: a) The negative control data (number of spontaneous revertants per plate) should be within the laboratory historical range for each tester strain. b) The positive control chemicals should produce responses in all tester strains, which are within the laboratory historical range documented for each positive control substance. Furthermore, the mean plate count should be at least three times the concurrent vehicle control group mean. c) The selected dose range should include a clearly toxic concentration or should exhibit limited solubility as demonstrated by the preliminary toxicity range-finding test or should extend to 5 mg/plate.
Data evaluation:
A test substance is considered negative (not mutagenic) in the test if: a) The total number of revertants in tester strain TA100 is not greater than two (2) times the concurrent control, and the total number of revertants in tester strains TA1535, TA1537, TA98 or WP2uvrA is not greater than three (3) times the concurrent vehicle control. b) The negative response should be reproducible in at least one independently repeated experiment. A test substance is considered positive (mutagenic) in the test if: a) The total number of revertants in tester strain TA100 is greater than two (2) times the concurrent control, or the total number of revertants in tester strains TA1535, TA1537, TA98 or WP2uvrA is greater than three (3) times the concurrent vehicle control. b) In case a repeat experiment is performed when a positive response is observed in one of the tester strains, the positive response should be reproducible in at least one independently repeated experiment. The preceding criteria were not absolute and other modifying factors might enter into the final evaluation decision. - Key result

Additional information
In a bacterial reverse mutation assay, performed according to OECD Guideline 471 and following GLP, the test substance was tested in the Salmonella typhimurium reverse mutation assay with four histidine-requiring strains of Salmonella typhimurium (TA1535, TA1537, TA98 and TA100) and in the Escherichia coli reverse mutation assay with a tryptophan-requiring strain of Escherichia coli (WP2uvrA). The test was performed in two independent experiments in the presence and absence of S9-mix (rat liver S9-mix induced by Aroclor 1254). The test substance was dissolved in dimethyl sulfoxide. In the dose range finding test, the test substance was tested up to concentrations of 5000 μg/plate in the absence and presence of S9-mix in the strains TA100 and WP2uvrA. The test substance did not precipitate on the plates at this dose level. In tester strain TA100, toxicity was observed at dose levels of 512 μg/plate and above in the absence and presence of S9-mix. In tester strain WP2uvrA, toxicity was observed at dose levels of 1600 and 5000 μg/plate in the absence and presence of S9-mix. Results of this dose range finding test were reported as part of the mutation assay. Based on the results of the dose range finding test, the test substance was tested in the first mutation assay at a concentration range of 5.4 to 1600 μg/plate in the absence and presence of 5% (v/v) S9-mix in tester strains TA1535, TA1537 and TA98. In an independent repeat of the assay, the test substance was tested at the same concentration range as the first assay in the absence and presence of 10% (v/v) S9 -mix in tester strains TA1535, TA1537, TA98, TA100 and WP2uvrA. Toxicity was observed in all tester strains. The test substance did not induce a significant dose-related increase in the number of revertant (His+) colonies in each of the four tester strains (TA1535, TA1537, TA98 and TA100) and in the number of revertant (Trp+) colonies in tester strain WP2uvrA both in the absence and presence of S9-metabolic activation. In this study, the negative and strain-specific positive control values were within the laboratory historical control data ranges indicating that the test conditions were adequate and that the metabolic activation system functioned properly. Based on the results of this study it is concluded that the test substance is not mutagenic in the Salmonella typhimurium reverse mutation assay and in the Escherichia coli reverse mutation assay.
Justification for classification or non-classification
The test substance does not have to be classified for mutagenicity according to Regulation (EC) No 1272/2008.
