Additional information
One study investigating the ready biodegradability of Sodium methyl cocoyl taurate is available. The GLP study was conducted under aerobic conditions according to OECD guideline 301B using non-adapted, domestic activated sludge as inoculum (Lebertz, 2005). Based on CO2 evolution a mean degradation of 82% was observed after 28 days. According to “OECD Guidelines for the testing of chemicals – Revised introduction to the OECD guidelines for testing of chemicals, Section 3 – Part 1: Principles and strategies related to the testing of degradation of organic chemicals degradation” published by OECD (2006) the ready biodegradability data for mixtures should be evaluated carefully. For substances with different chain lengths the 10-day window should not be used for the interpretation of the results. It is possible that a sequential biodegradation occurred which might have led to a prolonged lag-Phase and therefore a slower biodegradation period. In this case the pass level can be applied at 28 days. Hence, the test substance is determined to be readily biodegradable according to OECD criteria.
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.
