Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key information for classification
Water solubility:
68 mg/L (by CMC method)
Degradation:
Biodegradation: readily biodegradable (74 and 65% after 29 d, OECD 301B)
Bioaccumulation:
Log Kow =≥2.2 - < 3.2 at 20 °C (EU Method A.8, OECD 107, EPA OPPTS 830.7550 )
Aquatic acute toxicity:
- Aquatic invertebrates (freshwater): EC50 (48 h): 71 mg/L (Daphnia magna, OECD 202, based on the nominal concentrations)
- Algae (freshwater): ErC50 (72 h) 0.29 mg/L (Pseudokirchneriella subcapitata, OECD 201, based on the time weighted mean measured concentrations)
Aquatic chronic toxicity:
- Algae (freshwater): EC10 (72 h) 0.13 mg/L (Pseudokirchneriella subcapitata, OECD 201, based on the time weighted mean measured concentrations)
Conclusion on Classification
Based on the data above the substance (EC No. 263-218-7, CAS 61792-31-2) is rapidly biodegradable and has a moderate potential for bioaccumulation (Log Kow =≥2.2 - < 3.2). Acute toxicity data are available for two trophic levels (aquatic invertebrates and algae) whereas chronic toxicity was only investigated for aquatic algae. Based on the data for aquatic toxicity the substance needs to be classified and labelled as Acute Cat. 1 (H400) and Chronic Cat. 3 (H412) for environmental hazard according to the consolidated version of Regulation (EC) No 1272/2008 (dated: 01.01.2017) and further amendments (ATPs).
M-factor for acute aquatic toxicity: 1
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
