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.
