Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Partially unsaturated IQAC, DMS quaternised will strongly interact with soils, sediment and suspended matter in natural environment. It is technically not feasible to determine a concrete soil sorption coefficient
Key value for chemical safety assessment
Additional information
In a study according the EC C.19 guideline (OECD 121) the adsorption coefficient Koc of the test item was studied. It was found that the test item strongly interacted with the analytical column. The reference substance 2,4 -DDT was detected and had a retention time of 6.15 minutes. Based on the results obtained it was concluded that the test substance has a Koc value of higher than the reference substance 2,4-DDT. It corresponds with Koc and log Koc value for the test substance of>427,000 (log Koc>5.63, respectively.A concrete soil sorption coefficient could not be determined as the test itemwas not eluted from the column. In the guideline, however, it is stated that the method may not work for surface active substances and the results confirm this. Therefore this study is not appropriate to determine the soil sorption coefficient.
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.
