Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A test on biodegradation in soil is scientifically not necessary.
Key value for chemical safety assessment
Additional information
A test on biodegradation in soil is scientifically not necessary, as the substance hydrolyses rapidly in water at environmental pH (Half lifeat pH7 2.9 days at 20°C, 2.5 days at 25°C, and at pH 9 the half life is 1.2 days at 20 °C). Furthermore the substance proved to be inherently biodegradable (> 90% COD elimination after 28 d according to German Guideline DIN 38412, Part 25, corresponding to OECD 302 B). In a study conducted similar to OECD Guideline 303 A (Simulation Test - Aerobic Sewage Treatment. A: Activated Sludge Units), the closely related substance partially unsaturated IQAC, DMS quaternised (CAS 86088-85-9) was eliminated for > 90% in a modified activated sludge unit.
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.
