Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

The environmental classification of the substance is currently not harmonized according to the CLP Regulation (EC) 1272/2008.

Based on available acute ecotoxicity data, the lowest valid effect concentration for freshwater aquatic organisms is 49 mg/L (ErC50 value for algae). Based on available data the substance should not be classified for acute toxicity.

A biodegradation study was performed equivalent to the OECD 301B guideline under GLP conditions (Roulstone, 2014). Less than 22 % biodegradation was observed with the test substance after 28 days (DOC removal). The results support the conclusion that the biodegradation of the substance is low. Therefore the substance is considered not readily biodegradable; its logKow is < 4.

From the acute data, algae appear to be the most sensitive species. The ErC10 for algae is 5.3 mg/L; no other long-term studies are available, as the ErC10 for algae is higher than 1 mg/L, the substance should not be classified for chronic toxicity based on the acute toxicity values, following Annex I, table 4.1.0 b (i) of the CLP Regulation.
