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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In a ready biodegradability study DMATO was found to be 69% degraded by day 28 and the 10 -day window was met. Consequently, the substance is considered readily biodegradable and will degrade rapidly in the environment.
A HPLC adsorption study found that the log Koc of the substance was >5.63 (Koc = 427000), which indicates that the substance will adsorb strongly to soil and sediment and will be highly immobile in the environment.
In order to assess the bioaccumulation potential of the substance, QSAR estimations of the bioconcentration factor (BCF) were made for the most abundant components in the substance. It was found that the components varied largely in their potential for bioaccumulation, with BCF estimates ranging from 3.16 -2818 L/kg wet-weight. As such, it is assumed that certain components have an extremely low potential for bioaccumulation, while other components have some potential for bioaccumulation. Studies for hydrolysis and biodegradation simulation tests are not considered necessary as the substance has been shown to be readily biodegradable.
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.
