Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Workers - Hazard for the eyes

Additional information - workers

This substance is of low acute toxicity following oral exposure. The substance is not expected to be irritating to the skin or to the eyes and does not possess any skin sensitisation potential. On these bases no acute DNELs are required.

Data evaluating the genotoxic potential of the substance lead to conclusions that the substance is not genotoxic.

A GLP-compliant OECD 422 study, under the worst condition of oral gavage, set a parental NOEL at 150 mg/kg bw/day and the systemic NOAEL at 450 mg/kg bw/day. The reproductive and developmental of offspring to day 4 of lactation toxicity NOAELs were also established by this OECD 422 study, at the limit dose of 1000 mg/kg bw/day. The systemic NOAEL of 450 mg/kg bw/day is considered the appropriate endpoint to caluculate long-term DNELs for workers exposure. An additional assessment factor of 2 was applied because the data on reproductive and developmental toxicity are limited to the above mentioned OECD 422 study and no data on chronic toxicity are available.

Taken together, all the availalbe toxicological information suggests that the substance should be at most minimally absorbed.
