Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The available experimental data on the substances of the Alcohol Ethoxylates (AE) category indicates a rapid degradation of the substances under aerobic conditions. All test substances reached degradation rates > 60% and thus are regarded as readily biodegradable according to OECD criteria.  

The main mechanism of primary biodegradation for the linear and essentially linear AE is the central cleavage of the molecule, leading to the formation of long chain alcohol and polyethylene glycol (HERA, 2009; Marcomini et al., 2000a; Marcomini et al., 2000b). Alcohol ethoxylates are generally considered readily biodegradable under aerobic and anaerobic conditions (HERA, 2009).
