Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 28d, OECD 310)
- Bioaccumulation potential: Log Pow: 5.64 to 5.77 (at 23.4 °C) for the two isomers of the substance (EU Method A.8)
- Aquatic acute toxicity:
Fish: no data available
Aquatic invertebrates: EC50 (48 h) Daphnia magna = 127 µg/L (geometric mean measured concentration, OECD 202)
Algae: ErC50 (72 h) Pseudokirchneriella subcapitata >0.449 mg/L (based on time weighted average, OECD 201)
- Aquatic chronic toxicity:
Fish: no data available
Algae: ErC10 (72 h) Pseudokirchneriella subcapitata = 0.354 mg/L (based on time weighted average, OECD 201)
Aquatic invertebrates: no data available
Classification justification according to CLP
Based on the data above, the substance is considered to be rapidly degradable in the environment but has a potential for bioaccumulation (log Pow > 5). Based on the acute data from aquatic invertebrates (EC50 (48 h) = 127 µg/L) the substance has to be classified as “Aquatic Acute 1” (H400) and "Aquatic Chronic 1" (H410) according to the Regulation (EC) No 1272/2008 (CLP consolidated version dated 01.01.2017) and the Regulation (EU) No 1297/2014 (7th ATP).
M-factor (acute toxicity): 1
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
