Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information - workers

Based on the results from available studies, for workers, the most sensitive endpoints were general toxicity with endpoint-specific worker-DNELlong-termequal to 0.1 mg/kg bw/day for dermal route of exposure and 0.7 mg/m3 for inhalatory exposure.

DNEL(s) derivations were performed in accordance with the requirements of the ECHA Guidance on

Information Requirements and Chemical Safety Assessment, Chapter R.8: Characterization of dose [concentration]-response for human health.
