Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The following key information was used for the environmental classication:
Lowest acute E(L)C50 value 3.6 mg/L to Daphnia magna (Noack, 2001)
Lowest chronic NOEC value 30 µg/L to Daphnia magna (Dow Chemical Co., 1991)
Ready biodegradable in an OECD 301B test (Noack, 2001)
Log Kow: <-1.6 (Brekelmans, 2013)
GHS:
Acute: As the lowest EC50 value (to Daphnia magna) was >1 mg/L, the substance is not classified.
Chronic: Two chronic NOEC values are available (to daphnia and algae). As the lowest NOEC value (to Daphnia magna) was > 0.01 mg/L and ≤0.1 mg/L and the substance is ready biodegradable, the substance has to be classified in the Category Chronic 2 with H411.
DSD:
As the lowest EC50 value (to Daphnia magna) was >1 mg/L, the substance is ready biodegradable and the Log Kow <3, the substance is not classified.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
