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).
