Description of key information

Modified Small Vinyl Ester is a highly viscous prepolymer, which is placed on the market as an approximately 50% solution in a reactive diluent for industrial use only. When exposed to light, Modified  Small Vinyl Ester will polymerise and bind all Modified Small Vinyl Ester and most of the reactive diluent covalently in an extremely stable and highly water insoluble polymer with very low bioavailability in water. The LC50-48h for Daphnia magna was above the solubility limit in water of Modified Small Vinyl Ester. Modified Small Vinyl Ester is unlikely to reach water. See the CSA for further details. Thus, direct and indirect exposure of water, and consequently long-term effects are judged to be unlikely.

Additional information

Long-term toxicity testing on aquatic invertebrates is waived in accordance with REACH Annex IX, section 9.3.1, column 2. The LC50-48h for Daphnia magnawas above the solubility limit in water of Modified Small Vinyl Ester.
