Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In a study performed according to OECD 301B, SLMI is readily biodegradable (83.9% in 28d) and passes the 10day window.
A continuous activated sludge (CAS) test was performed with 14C- lauryl sulfoethyl ester, sodium salt according to guideline OECD 303A. The protocol was modified so that the fate of the test substance could be assessed at environmentally realistic concentrations using radiolabelled test substance along with un-labelled test substance. The total removal percentage as monitored from day 40 to day 72 range from 99.89 to 99.99% using 14C scintilation counting. This result demonstrates a near complete removal of parent compound at stringent STP considitions (SRT of 6 ± 1 day). Removal of the test substance from the influent through adsorption onto sludge ranged from 0.21 to 0.28%, demonstrating that the test substance was primarily removed by biodegradation (Gore, 2010).
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.
