Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Ames assay: negative
Micronucleus assay: negative
Additional information
Bacterial reverse mutation assay, Ames test on the test item showed negative results for TA 1535, TA 1537, TA 98, TA 100 strains and E. coli WP2 uvrA strain with and without metabolic activation.
Moreover an in vitro ctyogenicity micronucleus test was performed in order to strenghten the outcome of the Ames test. Tthe results confirmed that test item had no genotoxic effects in the human peripheral blood lymphocytes with as well as without metabolic activation.
Therefore, based on these results, the test item could be considered as not mutagenic.
Justification for classification or non-classification
According to the CLP Regulation (EC 1272/2008), Annex I, Part 3, substances which cause concern for humans owing to the possibility that they may induce heritable mutations in the germ cells of humans are classified in Category 2. This classification is based on positive evidence obtained in:
— somatic cell mutagenicity tests in vivo, in mammals; or
— otherin vivo somatic cell genotoxicity tests which are supported by positive results from in vitro mutagenicity assays.
Note: substances which are positive in in vitro mammalian mutagenicity assays, and which also show chemical structure activity relationship to known germ cell mutagens, shall be considered for classification as Category 2 mutagens.
In vitro mutagenicity tests are the following:
—in vitro mammalian chromosome aberration test;
—in vitro mammalian cell gene mutation test;
— bacterial reverse mutation tests.
Based on currently available data, the assessment on the genotoxic potential of target substance is negative.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
