Additional information
The test item was examined for the ability to induce gene mutations in tester strains of Salmonella typhimurium and Escherichia coli, as measured by reversion of auxotrophic strains to prototrophy according to the OECD 471 (1997). The five tester strains TA1535, TA1537, TA98, TA100 and WP2 uvrA were used. Experiments were performed both in the absence and presence of metabolic activation, using liver S9 fraction from rats pre-treated with phenobarbital and 5,6-benzoflavone (standard metabolic activation) in Main Assay I, and liver S9 fraction from uninduced hamsters (reductive metabolic activation system with Prival modification), in Main Assay II. The test item was used as a solution/suspension in sterile water for injection. The test item was assayed in the toxicity test at a maximum concentration of 2500 µg/plate and at four lower concentrations. At the end of the incubation period, no precipitation of the test item was observed with any tester strain, at any concentration tested, in the absence or presence of S9 metabolism. Neither toxicity, nor relevant increases in revertant numbers were observed with any tester strain at any dose level, in the absence or presence of S9 metabolism. On the basis of toxicity test results, in order to evaluate a potential mutagenic effect up to cytotoxic or insoluble concentrations, in the Main Assays an additional dose level of 5000 µg/plate was employed. In Main Assay I, using the plate incorporation method, the test item was assayed at six dose levels from 156 to 5000 µg/plate. As no relevant increase in revertant numbers was observed at any concentration tested, Main Assay II was carried out. Based The experiment was performed using the pre-incubation method in the presence of a reductive metabolic system. The test item was assayed at six dose levels from 156 to 5000 µg/plate. Neither precipitation of the test item, nor toxicity was observed at the end of the incubation period, with any tester strain, at any concentration tested, in the absence or presence of S9 metabolism, in any experiment. The test item did not induce two-fold increases in the number of revertant colonies in the plate incorporation or pre-incubation assay, at any dose level, in any tester strain, in the absence or presence of any metabolic activation system.
It is concluded that the test item does not induce reverse mutation in Salmonella typhimurium or Escherichia coli in the absence or presence of S9 metabolism, under the reported experimental conditions.
Justification for classification or non-classification
According to the CLP Regulation (EC 1272/2008), for the purpose of the classification for germ cell mutagenicity, substances are allocated in one of two categories in consideration of the fact that they are:
- substances known to induce heritable mutations or to be regarded as if they induce heritable mutations in the germ cells of humans or substances known to induce heritable mutations in the germ cells of humans or
- substances which cause concern for humans owing to the possibility that they may induce heritable mutations in the germ cells of humans.
Based on the results of mutagenicity (AMES), no classification for mutagenetic toxicity is warranted under the CLP Regulation (EC 1272/2008).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
