Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key value for chemical safety assessment
Justification for classification or non-classification
No carcinogenicity study exists for the registration substance. However, the available genetic toxicity studies give no indication of genetic toxicity, nor do the repeated dose studies show any indication of hyperplasia and/or pre-neoplastic lesions. As such, the registration substance is not classified as carcinogenic.
Additional information
REACH Annex X, Section 8.9.1, Column 2 states:
"A carcinogenicity study may be proposed by the registrant or may be required by the agency in accordance with Articles 40 or 41 if:
- the substance has a widespread dispersive use of there is evidence of frequent or long-term human exposure, and
- the substance is classified as germ cell mutagen category 2 or there is evidence from the repeated dose study(ies) that the substance is able to induce hyperplasia and/or pre-neoplastic lesions."
The available genetic toxicity studies show an absence of any genetic toxicity, as such the registration substance is not classified as a germ cell mutagen. The repeated toxicity studies (OECD 407 and 408) did not show any significant toxicological findings, notably there was no evidence of hyperplasia and/or pre-neoplastic lesions. Therefore, in accordance to the aforementioned REACH text, the carcinogenicity study is waived.
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.
