Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A Mackay level III distribution was calculated using the EPI Suite™ ver. 4.10 (US-EPA, 2008) for releases of the methacrylate esters to air and water, but not soil, because there are no direct emissions to soil. The Mackay III calculations result in the following theoretical partitioning into the standard compartments.

When released to air, EGDMA preferentially partitions to soil and to a lesser degree to water, but also maintains a significant presence in air. Partitioning to sediment is low.When released to water all EGDMA tends to stay in the compartment where it was released.
EGDMA has a low vapour pressure and a high water solubility and consequently a low Henry constant. Epiwin model calculations indicate a low volatilisation potential.
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.
