Description of key information
Additional information
Modified Small Vinyl Ester was evaluated to be not readily biodegradable. Ready biodegradability of Modified Small Vinyl Ester was assessed conducting a modified Sturm test compliant with GLP. Modified Small Vinyl Ester did not inhibit microbial activity in the toxicity control. The relative biodegradation values calculated from the measurements performed during the test period revealed no significant biodegradation of Modified Small Vinyl Ester. This result may be due to low bioavailability of Modified Small Vinyl Ester.
Water simulation testing is waived in accordance with REACH Annex IX, section 9.2.1.2, column 2. Modified Small Vinyl Ester is only slightly soluble in water. Modified Small Vinyl Ester is a highly viscous prepolymer, which is placed on the market as an approximately 50% solution in as reactive diluent. Modified Small Vinyl Ester will polymerise to an insoluble polymer. Exposure of the aquatic environment is unlikely. See the CSA for further details.
Soil simulation testing is waived in accordance with REACH Annex IX, section 9.2.1.3 column 2, because Modified Small Vinyl Ester is a highly viscous prepolymer, which is placed on the market as an approximately 50% solution in a reactive diluent. Modified Small Vinyl Ester will polymerise to an insoluble polymer with very low bioavailability in soil. Modified Small Vinyl Ester is unlikely to reach soil thus direct and indirect exposure of soil is judged to be unlikely. See the CSA for further details.
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.
