Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Dimethyldisulfure has not be found to be readily biodegradable, but still reaching 50-60% mineralisation within 28 days.

Key value for chemical safety assessment

Biodegradation in water:
inherently biodegradable

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.
