Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
EC50 (48 h) > 110 mg a.i./L (nominal) (D. magna, OECD 202)
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 aquatic invertebrates 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 aquatic invertebrates was investigated under static conditions according to OECD 202. The test was performed with limit concentration of 110 mg a.i./L. The test concentration was analytically monitored by LC-MS/MS. Recovery rates were ≥ 99% of nominal. No immobilisation was observed. The determined EC50 (48 h) > 110 mg a.i./L (nominal).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
