Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based upon read-across to Coco fatty acids 2-sulfoethyl ester, sodium salt , lauric acid 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
Based upon read-across to Coco fatty acids 2-sulfoethyl ester, sodium salt, Lauric acid 2-sulfoethyl ester, sodium salt is readily biodegradable, as shown in OECD Guideline tests. The removal of both short (Lauryl, C12) and the longest (Stearyl, C18) chained fatty acid isethionates was extensive with 99.8% and even greater for the short chain lauryl, C12 at 99.88%. Results from the river die away study show that the measured half-life of Lauric acid 2 -sulfoethyl ester, sodium salt is 0.21h at 20 C.. The value (99.8%) for the short (Lauryl, C12) and the longest (Stearyl, C18) chained fatty acid isethionates were used for the risk assessment demonstrating a conservative, worst case scenario, as the removal rates for the lauric acid 2-sulfoethyl ester, sodium salt (shorter C12) are better at 99.88%.
It can therefore be assumed that it degrades rapidly in the aquatic environment under aerobic conditions without formation of persistent degradation products.
Biodegradation in soil
Based upon read-across to Coco fatty acids 2-sulfoethyl ester, sodium salt , lauric acid 2-sulfoethyl ester, sodium salt
is readily biodegradable.Lauric acid 2-sulfoethyl ester, sodium salt 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).
