Description of key information

Both constituents of the submission substance (BHMT and HMD) were assessed separately for biodegradability and proved to be readily biodegradable within 28 days including total nitrification and meeting the 10-day window requirement. 

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Reliable (RL category 1) ready biodegradability tests (Closed bottle tests, OECD 301 D) performed compliant to GLP are available for both constituents of submission substance (BHMT and HMD). Both compounds proved to be readily biodegradable including fulfilment of the 10-day window requirement and total nitrification.
