Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Reliable (Klimisch 1) experimental aquatic toxicity data are available for the registered substance for aquatic invertebrates and algae. Results showed a 48 hour EL50 value based on mobility on Daphnia magna of 6.9 mg/L and a 72 hour EL50 value based on algal yield of Pseudokirchneriella subcapitata of 5.7 mg/L (95% CL: 4.6 - 7.0 mg/L).
A reliable (Klimisch 1) ready biodegradability study is available for the registered substance which resulted in 14% biodegradation after 28 days, therefore concluding that the substance is not readily biodegradable.
Conclusion on classification
Available experimental study data show aquatic toxicity EL50 values between 1 – 10 mg/L and that the registered substance is concluded to be not readily biodegradable and have an overall log Kow value of >6.5.
The registered substance is therefore classified as Aquatic Chronic 2 for the environment according to the Annex VI of the Regulation (EC) No. 1272/2008 (CLP).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
