Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Local effects

Hazard assessment conclusion:
no hazard identified

Additional information - workers

No adverse effects upon which DNELs for workers could be based have been seen in any of the available toxicity studies. In accordance with ECHA Guidance Document Chapter R.8, therefore, DNELs for acute effects have not been derived. The physico-chemical properties of the substance demonstrate that there is negligible potential for inhalation exposure to the substance; consequently, no inhalation DNELs have been derived. Based on an absence of toxicity in the available studies, a long-term dermal DNEL for systemic effects in workers of 10 mg/kg bw/day is proposed based on the 90-day oral toxicity study in rats in which a NOAEL of 1,000 mg/kg bw/day was identified (the highest dose tested).

Additional information - General Population

No adverse effects upon which DNELs for general population could be based have been seen in any of the available toxicity studies. In accordance with ECHA Guidance Document Chapter R.8, therefore, DNELs for acute effects have not been derived. The physico-chemical properties of the substance demonstrate that there is negligible potential for inhalation exposure to the substance; consequently, no inhalation DNELs have been derived.

Based on an absence of toxicity in the available studies, a long-term oral DNEL for systemic effects in the general population and a long-term dermal DNEL for systemic effects in the general population, each of 5.0 mg/kg bw/day are proposed based on the 90-day oral toxicity study in rats in which a NOAEL of 1,000 mg/kg bw/day was identified (the highest dose tested).
