Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
As no study is available for assessing the biodegradability of the substance, a read-across to structurally related Alkyl Dimethyl Betaines was applied, in accordance to Regulation (EC) No. 1907/2006 Annex XI, 1.5 Grouping of substances. The read across is justified due to the structural similarity of the analogue substances and similar physico-chemical properties resulting in a similar environmental fate and ecotoxicity profile. Further justification is given in the analogue justification attached to section 13 in IUCLID.
Based on experimental studies the substance can be considered as readily biodegradable according to OECD criteria. Hydrolysis is not relevant in regard to abiotic degradation in the environment due to the readily biodegradability of the test substance. Due to the experimental determined log Kow of 2.73 a significant bioaccumulation in aquatic organisms and high adsorption potential to organic soil and sediment particles is not expected which is supported by a calculated log Koc of 2.4.
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.
