Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The Koc value of Modified Small Vinyl Ester is calculated to 14,600 (log Koc is 4.16) at 35 °C based on the experimental data for the two main constituents of Modified Small Vinyl Ester (bisGMA, ca. 57% and its monomaleic adduct, ca. 14.5%). The high values indicate that Modified Small Vinyl Ester will bind tightly to soils and sediments and thus, reduce overall exposure potential. Monomaleic adduct of bisGMA is an organic acid that is fully ionised at neutral pH. It has a low Koc value (18) at this pH and may not bind tightly to soils and sediment. However, Modified Small Vinyl Ester is a highly, viscous liquid that is marketed as an approximately 50% solution in a reactive diluent. Modified Small Vinyl Ester will polymerise to an insoluble polymer and become immobilised in the environment.
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.
