Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In the key study a LC50 for fish of 1.2 mg test material/L (corresponding to 0.876 mg a.s./L) could be determined after 96 h exposure.
Nevertheless that endpoint is not used for PNEC-calculation as PNEC-values were calculated on the basis of a HC5-approach.
Key value for chemical safety assessment
Additional information
For the mixture C12-C18 alcohol ethoxylate, CAS 68213-23-0, no acute toxicity study on fish is available. Thus, a category read-across to the GLP-study conducted with CAS 68439-50 -9 according to EU method C.1, is made (Scholz, Sasol, 1995). In this study, for the alcohol ethoxylate mixture C12 -C14 ethoxylated with 2 EO, an EC50 -value of 1.2 mg/L based test material (corresponding to 0.876 mg/L based active substance) is reported.
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.
