Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

EC50 (96 h) > 120 mg a.i./L (nominal) (P. promelas, OECD 203)

Key value for chemical safety assessment

Additional information

The assessment is based on the data currently available. New studies, based on the category review and the final decisions issued for some of the category substances, which are also relevant for this assessment, are currently being conducted. The hazard assessment with respect to aquatic toxicity will be updated once all ongoing studies have been finalised.

The acute toxicity of Alcohols, C8-10, ethoxylated, sulfates, sodium salts to fish was assessed in a weight of evidence approach based on the grouping of substances (category approach).

For the assessment of acute toxicity of the target substance, a category read-across to Alcohols, C8-10, ethoxylated, sulfates, ammonium salts was conducted.

The acute toxicity of Alcohols, C8-10, ethoxylated, sulfates, ammonium salts to fish was investigated in a semi-static limit test following OECD guideline 203 (GLP). Seven fish of the species Pimephales promelas were exposed to a nominal test substance concentration of 120 mg a.i./L. The test medium was renewed every 48 during the 96 h test period. The test concentrations was analytically verified by measuring the concentration of eight representative constituents by LC-MS/MS. Samples for analysis were taken from fresh and aged medium. The time weighted mean measured concentrations, based on the eight representative constituents of the UVCB substance was 96 mg a.i./L. No mortality or toxic symptoms were observed. The determined EC50 (96 h) was > 120 mg a.i./L nominal (EC50 (96 h) > 96 mg a.i./L, TWA).
