Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Classification related key information
- Biodegradation: readily biodegradable according to OECD criteria (79% after 28 d, OECD 301D)
- Bioaccumulation: log Pow 4.10 (OECD 117)
- Aquatic acute toxicity:
Aquatic invertebrates: EC50 (48 h) Daphnia magna = 2.3 mg/L (arithmetic mean measured, OECD 202)
Algae: ErC50 (72 h) Pseudokirchneriella subcapitata = 0.23 mg/L (geometric mean measured, OECD 201)
- Aquatic chronic toxicity:
Algae: ErC10 (72 h) Pseudokirchneriella subcapitata = 0.15 mg/L (geometric mean measured, OECD 201)
Classification justification according to CLP
The substance is readily biodegradable but is expected to have a potential for bioaccumulation (Log Kow: 4.1 at 20 °C; OECD 117, HPLC method). Aquatic toxicity studies are available for aquatic invertebrates (EC50 (48 h): 2.3 mg/L) and aquatic microalgae (ErC50 (72 h): 0.23 mg/L; ErC10 (72 h): 0.15 mg/L). Therefore, the substance is classified as “Aquatic Acute 1” and “Aquatic Chronic 2” according to the consolidated version of Regulation (EC) No 1272/2008.
M-factor acute: 1
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.
