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.
