Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
Acute aquatic data are available for three trophic levels for the test item and read-across substances. No effects were seen in any of the tests at up to 100 mg/L. The test item achieved biodegradation of 36 % after 28 days and therefore is considered to be not readily biodegradable. Since the effect value is > 100 mg/L, the test item does not need to be classified for acute aquatic hazard.
Chronic toxicity data are only available for algae for the test item. Based on a NOELR of 25 mg/L, the substance does not need to be classified for chronic aquatic toxicity.
However, as chronic toxicity data are only available for one trophic level, acute toxicity together with environmental fate data are also assessed. The test item is considered to be not readily biodegradable. The short-term EC50/LC50 values are > 100 mg/L, therefore the test item is not considered as hazardous to aquatic environment with long-lasting effects and no classification for chronic toxicity is required.
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.
