Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The test substance has low oral, inhalation, and dermal toxicity in the rat. The rat oral and dermal LD50s were >5000 mg/kg body weight. The only clinical sign observed was reduced faecal volume in one rat on Day 1 of the oral study. No other effects in clinical signs, body weight, or gross necropsy were observed in either study. The rat 4-hour inhalation LC50 was >5.06 mg/L, the highest concentration tested. Following exposure, all animals exhibited irregular respiration, but recovered by Day 2. Some rats exhibited weight loss on day 1. No other effects were observed during the study or at gross necropsy.

Justification for classification or non-classification

Based on oral and dermal LD50s in rats of >5000 mg/kg, and a 4-hour inhalation LC50 in rats of >5.06 mg/L, no classification is required for acute toxicity endpoints according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) regulation (EC) No. 1272/2008.
