Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Fish embryo toxicity and toxicity to Daphnia studies are available with the read across substance, ‘mono- and di- C16-18 PSE and C16-18 AE10 PSE’ and/or on substance representative of the main constituents, which were categorised as aclohol phosphates (PSE) and ethoxylated phosphate ester (AE PSE). An algae study was available with the test substance. Based on the available studies, Daphnia has been identified to be the most sensitive species. The lowest short-term 48h EC50 value from the Daphnia study with representative constituent AE (i.e., C12-13 AE5) was determined at 1 mg/L (nominal) and the long-term equivalent ErC10 value from the algae study was determined at 0.965 mg/L (measured). Overall, based on the available results from short-term studies and considering that the substance is not readily biodegradable, the test substance, ‘mono- and di- C18-unsatd. PSE and C18 AE5 PSE’, warrants an Acute 1 and Aquatic Chronic 1; H410: ‘Very toxic to aquatic life with long-lasting effects’ according to EU CLP criteria (Regulation 1272/2008/EC). M factors to be applied are 1 for acute and 1 for chronic toxicity.
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).
