Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Aquatic Acute 1, H400
- Aquatic Chronic 1, H 410
- M factors to be applied are 10 for acute and 10 for chronic toxicity.
According to Regulation (EC) No. 1907/2006 only short-term toxicity studies of the substance for aquatic organisms are available.
There are no data for long-term (chronic) toxicity of the substance for aquatic organisms are availbale.
Therefore, based on available data, the lowest value for acute aquatic toxicity of algae is EC50 (72h) = 24 µg/l which was adopted for the calculation of a PNEC. Thus, the resulted PNEC values are very low. Adequate chronic toxicity data are recommended. Nevertheless, it must be taken into account that the substance is surface active and not readily biodegradable. For this reason, special caution is required.
According to Regulation (EC) n. 1272/2008, the substance should be classified for the aquatic toxicity due to the toxic effects to fish, daphnia and algae in tests according to OECD 203, OECD202 and OECD 201, resp.
The self-classification of the substance is:
