Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Classification according to CLP

Acute toxicity data are available for all three trophic levels whereas chronic data are only available for algae. The test substance is not readily biodegradable, but biodegradable within 28 days, and has a low potential for bioaccumulation (log Kow < 4.5). Fish was found to be the most sensitive species with a LC50 (96 h) of 3.19 mg/L. Following Regulation (EC) 1272/2008, 10. ATP (2017) the substance is not classified as acutely hazardous to the aquatic environment. However, the substance is not readily biodegradable and chronic aquatic data are only available for algae. Therefore, acute data of the other trophic levels needs to be considered to decide about the chronic classification as well. As the lowest effect value is lower than 10 mg/L (fish: Isoamyl isovalerate 96 h- LC50 = 3.19 mg/L), the substance has to be classified as chronically hazardous with chronic aquatic category 2 (H411).
