Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
For the registration substance only acute aquatic toxicity data for all three trophic levels are available. Algae is the most senstive species with an ErC50 (72h) 0.35 mg/L and an ErC10 (72h) of 0.21 mg/L. This results in an acute classification. As no chronic data are available it could be assumed that the chronic data could be derived from the acute data with an asssessment factor of 10. This would result in a NOEC chronic fish 0.15 mg/L and NOEC chronic daphnia of 0.45 mg/L. For algae the ErC10 (72h) of 0.21 mg/L can be used. As these chronic values are >0.1 mg/L and <= 1 mg/L and the registration substance is readily biodegradable a chronic classification category chronic 3 seems to be most appropriate,
CONCLUSION
Based on the available data on ecotoxicty and biodegradation the following classification according CLP 1272/2008/EEC applies
Short-tern aquatic hazard: Category Acute 1, M factor 1
Long-term aquatic hazard: Category Chronic 3, no M factor
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
