Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Two key studies have been performed to test the ready biodegradability following the OECD 301B CO2 evolution test methods.
The first study was performed on SLMI and showed biodegradability of >80% in 28days and passed the 10d window.
The second study was performed on the read-across substance SCMI (Rodrigue, 2007) and measured biodegradation of >60% at the end of 10 days, showing ready biodegradation of the substance.
In a study performed to OECD 121, SLMI was determined to have a log10Koc value of less than 1.3 (Koc <20)
In a study with 14C- lauryl sulfoethyl ester, sodium salt according to guideline OECD 303A, a near complete removal of parent compound at stringent STP considitions (SRT of 6 ± 1 day) was found. 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.
