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.
