Additional information
Conclusion on classification
Environmental fate and pathways
Biodegradation
Readily biodegradable: 70% after 28 d (OECD 301 F)
Bioaccumulation
Log Kow = -4.38 (EpiSuite v4.11, KOWWIN v1.68)
Aquatic acute toxicity
Fish
No effects after 70 h, up to 415 mg/kg body weight (nominal, Cyprinus, carpio, non-guideline, non-GLP, RA-A CAS 520-45-6)
Aquatic invertebrates
EC50 (48 h) > 100 mg/L (nominal, Daphnia magna, OECD 202)
Algae
ErC50 (72 h) = 32.1 mg/L, (nominal, P. subcapitata, OECD 201)
Aquatic chronic toxicity
Aquatic algae
ErC10 (72 h) = 23.9 mg/L (nominal, Pseudokirchneriella subcapitata, OECD 201)
Classification according to CLP
Algae were the most sensitive trophic level. The ErC50 (72 h) of algae was 32.1 mg/L and the ErC10 (72 h) was 23.9 mg/L. Since the substance is readily biodegradable and shows no potential for bioaccumulation, it is not classified and labelled for environmental hazards according to 7th ATP of Regulation (EC) No 1272/2008 based on the available data.
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.
