Additional information

Based on the result of a CO2 headspace test according to ISO 14593, Sodium N-lauroylsarcosinate (CAS 137-16-6) can be regarded as readily biodegradable according to the OECD criteria. The substance is thus considered to be rapidly degraded by both aquatic and terrestrial microorganisms. Therefore, in accordance with Regulation (EC) No 1907/2006, Annex IX, column 2, 9.2.1.2 - 9.2.1.4, further simulation testing for biodegradation in water, sediment or soil is not necessary.
