Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
GHS:
Acute:
As the lowest EC50 value (to daphnia) was >1 mg/L, the substance has no classification in an Acute Category.
Chronic:
The NOEC to algae value is used as long-term NOEC for GHS classification, because there is no indication from the results of the acute tests that fish or daphnia are more sensitive. With one chronic NOEC available, the classification in a Chronic Category must be evaluated based on the criteria for chronic toxicity data and the criteria for acute toxicity data. The most stringent outcome should prevail.
Classification based on chronic toxicity data: Since the NOEC to algae was >1 mg/L the substanced has no classification in a Chronic Category based on classification with chronic data.
Classification based on acute toxicity data: Since the lowest EC50 value (to daphnia) is >10 to ≤100 mg/L and the substance is not rapidly biodegradable, the substance has to be classified in Category Chronic 3.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
