Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Self-classification according to REGULATION (EC) No 1272/2008 (CLP):
The substance is not to be classified for acute aquatic hazards since the acute toxicity is >10 to <=100 mg/L.
From acute toxicity data, no chronic hazard category does result because the substance is readily biodegradable and does not bioaccumulate significantly (experimentally determined BCF <= 500).
The only available chronic ecotoxicity data are from the study on freshwater green algae, for which an EC10 (72 h; growth rate) of 45 mg/L had been determined. This value is above the limit for readily degradable substances given in REGULATION (EC) No 1272/2008. Accordingly, no chronic hazard category does result from available long-term data.
Overall, according to REGULATION (EC) No 1272/2008 there are no classification requirements for environmental hazard.
Self-classification according to UN-GHS ST/SG/AC.10/30 /Rev.7 (2017)
Because of E(L)C50-Values between 10 and 100 mg/L, the following acute toxicity classification applies:
o Aquatic Acute 3
o H402: Harmful to aquatic life.
For chronic aquatic toxicity, no classification is applicable (see EU-GHS above for details).
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.
