Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Carcinogenicity
Administrative data
Description of key information
Not specifically tested for this endpoint. However, no adverse or proliferative lesions were produced in the acute or repeated dose oral studies, and the acute dermal study. No adverse or proliferative respiratory tissue produced in the acute inhalation study. Not mutagenic nor clastogenic. No evidence of reproductive or teratogenic effects by the oral route.

Justification for classification or non-classification
The substance is not classified for mutagenicity. Additionally, no tissue damage or systemic effects, including microscopic evidence of cell hypertrophy, hyperplasia, or pre-neoplastic lesions were observed during a repeated oral toxicity-one generation reproduction study, up to the highest dose tested (1000 mg/kg bw/day). Therefore, the substance is considered non-carcinogenic. The substance does not need to be classified for carcinogenicity according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
Additional information
The test substance did not produce mutagenicity or genetic damage when tested in bacterial and mammalian cell cultures. Carcinogenicity is not predicted. Additionally, no tissue damage or systemic effects were observed during a repeated dose oral toxicity/one-generation reproduction study up to the limit dose of 1000 mg/kg/day, No such effects were observed in acute oral or dermal toxicity studies up to 5000 mg/kg/day or in an acute inhalation study up to 0.89 mg/L, the highest achievable concentration. The lack of active genetic and epigenetic effects support the position that carcinogenicity is not likely to be a concern with this test substance.
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.
