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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Dimethyldisulfide has been found to be not readily biodegradable,with less than 10% of biodegradation after 28 days, in a GLP study, according to OECD 301 D guideline (closed bottle test). In another study, carried out according to OECD 310 and GLP, dimethyldisulfide was found to be partly biodegradable with a 50 - 60% mineralisation (CO2 evolution) within 28 days.
Due to intrinsic properties of DMDS (high volatility and low sorption potential), simulation tests are not deemed necessary. In spite of this OECD 308 has been carried out in the frame of another regulatory need: it has been verified that 14C-DMDS spiked in a water/sediment system is rapidly flushed out in the atmosphere without any detectable biodegradation.
Soil biodegradation studies have been
carried out according to OECD 307 in aerobic and anaerobic conditions.
It has been shown that in aerobic conditions carbon dioxide and
methanesulfonic acid are formed, when in anaerobic conditions it is
methanethiol.
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.
