Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis:
According to Regulation (EC) 1907/2006 Annex VIII 9.2.2.1 column 2 a study on hydrolysis does not need to be conducted if the substance is readily biodegradable. In a screening test on biodegradability following to OECD guideline 301A (DOC Die-Away Test) the test substance was degraded to 90-100% and is classified as readily biodegradable. An experimental investigation of its hydrolytic properties was considered as scientifically unjustified.
Biodegradation in water: screening test:
The ready biodegradability of the test substance potassium N,N-dimethylglycinate was tested in a GLP guideline study according to OECD 301A (BASF 01/0456/21/1, 2002). The biodegradation was between 90 and 100% based on DOC removal after 14 days. Based on these data, the test substance is considered to be readily biodegradable.
Adsorption / Desorption:
According to Regulation (EC) 1907/2006 Annex VIII 9.3.1 column 2 a screening test on adsorption desorption does not need to be conducted if the substance - based on its physicochemical properties - can be expected to have a low potential for adsorption (e.g. the substance has a low octanol water partition coefficient), or if the substance and its relevant degradation products decompose rapidly. Since the substance has a very low n-octanol water partition coefficient (Log Pow (experimental) = -3.7; Log Pow(QSAR) = - 2.73) experimental data on the adsorption/desorption was not provided.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.
