Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The environmental fate and behaviour of the registered substance was determined via endpoint testing for hydrolysis, biodegradation and the adsorption/desorption coefficient. The soil adsorption coefficient of the registered substance was determined via read across to the results of testing on the structurally similar substance tosyl salt. The Log Koc of the acid component of the substance was found to be <1.3 at 25°C. Conducting a bioaccumulation study is considered scientifically unjustified as the substance has a low Log Kow of -0.43. A Low Kow indicates a low potential for bioaccumulation and therefore further animal testing is considered unjustified. The biodegradation potential of the registered substance was determined via read-across to testing on the structurally similar substance tosyl salt. The ready biodegradability of the registered substance was determined via read-across to the results of biodegradation testing on a structurally similar substance (tosyl salt). The substance was found to be inherently biodegradable.
Where appropriate, data has been provided for a second triethanolamine salt (tosyl salt), which is structurally similar substance to the registered substance. Read-across between the registered substance and tosyl salt is considered justified owing to the structural similarity of the two substances. Both are salts of a carboxylic acid and triethanolamine. The acid components are structural isomers and differ only in the position of a single methyl group in the N-methyl salt. This is not expected to change the behavior or properties of the substances, and both substances have shown similarity in the results of physical and chemical endpoint testing, for example, the partition coefficient of the N-methyl salt was found to be -0.43 (mean Log Kow), compared with a mean Log Kow of -0.41 for the tosyl salt. The water solubilities were also found to be comparable, with both salts showing a solubility of >50% via visual assessment.
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.
