Gene Mutation Assays

A Bacterial Reverse mutation Assays (Ames test) was performed according to the OECD 471 test guideline with the substance. The study (2013) was selected as a key study. No significant increases in the frequency of revertant colonies were recorded for any of the bacterial strains in both experiments, with any dose of the test material, either with or without metabolic activation. The study results indicate that the substance does not induce gene mutations in bacteria, whereas all positive control chemicals (with and without metabolic activation) induced a significant increase in the number of of colonies.The substance was therefore considered as non-mutagenic in the Ames test.

A mammalian cell gene mutation assay in L5178Y cells was performed according to the OECD 476 test guideline with the substance. The study (2013) was selected as a key study. No significant increases in the frequency of mutant colonies was recorded, either in the absence or presence of metabolic activation.

The substance did not induce gene mutations in L5178Y cells under activation and non-activation conditions, whereas both positive control chemicals (with and without metabolic activation) induced significant increases in the frequency of mutations.The substance was therefore considered as negative for inducing gene mutations in L5178Y cells under the activation and non-activation conditions used in this assay.

 

Chromosomal aberration

The clastogenic potential of the substance was determined using an in vitro chromosome aberration test in Human Lymphocyte cells, which measures the potential of a substance to increase the incidence the of structural chromosome aberrations in cultured cells.

None of the test substance dose levels, up to the cytotoxicity limit, either with or without metabolic activation, induced significant increases in the frequency of cells with aberrations in either of two experiments. The substance does not induce structural aberrations in the chromosomes of HL cells under activation and non-activation conditions, whereas both positive control chemicals (with and without metabolic activation) induced significant increases in the frequency of aberrant cells.The substance is therefore considered as negative for inducing chromosomal mutations in HL cells under the activation and non-activation conditions used in this assay.

Short description of key information:
- Ames Test 2013 (OECD 471, GLP, K, rel. 1): non mutagenic up to 5000 µg/plate in S. typhimurium TA 1535, TA 1537, TA 98, TA 100 & WP2uvrA-
- Human lymphocyte chromosome aberration test 2014 (OECD 473, GLP, K, rel. 1): non clastogenic up to cytotoxic limit
- Gene mutation assay in mouse lymphoma L5178Y cells 2013 (OECD 476, GLP, K rel1): non mutagenic up to cytotoxic limit

Endpoint Conclusion: No adverse effect observed (negative)

Justification for classification or non-classification

Harmonized classification:

The substance has no harmonized classification for human health according to the Regulation (EC) No. 1272/2008 including the ATP2.

Self classification:

Based on the available data, no additional classification is proposed according to the Annex VI of the Regulation (EC) No. 1272/2008 (CLP) and of the Directive 67/548/EEC.
