Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Abiotic degradation
Coco fatty acids 2-sulfoethyl ester, sodium salt is considered to be hydrolytically stable at pH 4.0, 7.0 and 9.0 with a half-life equal to or greater than a year at ambient temperature. However, since Coco fatty acids 2-sulfoethyl ester, sodium salt is readily biodegradable, abiotic degradation is of limited relevance for its environmental fate.
Biotic degradation
Biodegradation in water and sediment
Coco fatty acids 2-sulfoethyl ester, sodium salt is readily biodegradable, as shown in OECD Guideline tests. It can therefore be assumed that it degrades rapidly in the aquatic environment under aerobic conditions without formation of persistent degradation products. For risk assessment the default half-life's in water and sediment of resp15 and 30 days will be used.
Biodegradation in soil
Coco fatty acids 2 -sulfoethyl ester, sodium salt is readily biodegradable and has with a Koc of 1451 L/kg a limited sorption to soil. It can therefore be assumed that it degrades rapidly in the terrestrial compartment under aerobic conditions. For risk assessment the default half-life in soil of 30 days will be used.
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.
