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

Both the oral and dermal toxicity test revealed LD50 > 2000 mg/kg bw.

Key value for chemical safety assessment

Additional information

In 1996 laboratories of Ciba, Switzerland, performed oral and dermal acute toxicity tests with the test item CA 2342 A. 2000 mg/kg bw was the highest test item dose being tested (limit test). Both the oral and dermal toxicity test revealed LD50 > 2000 mg/kg bw. There were no in-life observations indicating treatment-related systemic effects. All animals survived to scheduled sacrifice.

Justification for classification or non-classification

The substance is not classified as acute toxic by EU-GHS (CLP), since LD50 > 2000 mg/ kg body weight, which is the cut-off in the EU's GHS classification system for acute oral and dermal toxicity.

UN-GHS has a Category 5 for acute oral toxicity for the dose range 2000 mg/kg bw < LD50 < 5000 mg/kg bw, a concentration range which has not been tested. However acute toxicity Category 5 is applied by some authorities only. Furthermore, acc. to GHS 3.1.2.5 testing animals in the Category 5 range is discouraged unless "there is a strong likelyhood that results of such testing would have a direct relevance to the protection of human health", which is not the case.
