Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

biodegradation in water: ready biodegradability
Type of information:
read-across based on grouping of substances (category approach)
Adequacy of study:
weight of evidence
Justification for type of information:

Key result
Parameter:
other: % degradation
Value:
> 60 - <= 100
Sampling time:
28 d

For detailed information and assessment of the biodegradability of the Alcohol Ethoxylates (AE) category, please refer to the category justification documentation attached to the category object.

Interpretation of results:
readily biodegradable
Conclusions:
The ready biodegradability of the target substance was assessed in a weight of evidence approach based on the grouping of substances (category approach). The substances of the Alcohol Ethoxylates (AE) category are readily biodegradable according to OECD criteria.
Executive summary:

The ready biodegradability of the target substance was assessed in a weight of evidence approach based on the grouping of substances (category approach). 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.  

Description of key information

Readily biodegradable: >=60 - 100% in 28 days 

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable
