Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 an EC10 for microorganisms based on cell growth inhibition > 10 g/L is determined after approximately 17 h.

Key value for chemical safety assessment

Additional information

For the alcohol ethoxylate mixture C12 - C18 with up to 2.5 EO (CAS 68213-23-0) no study on microorganisms is available. Thus, a category read-across to the GLP-study conducted with a mixture of C12 - C14 alcohol ethoxylates containing approximately 6EO according to DIN 38412, part 8 is made (Diefenbach, Sasol, 1996).

In this study an EC10 -value > 10 g/L based on cell growth inhibition could be determined. That value is used for PNEC-calculation.
