Additional information
Modified Small Vinyl Ester is a highly viscous prepolymer, which is placed on the market for industrial use only as an approximately 50% solution in a reactive diluent. Modified Small Vinyl Ester solutions are used under controlled conditions to ensure safe use and to avoid release of primarily the reactive diluent to the environment. In case of incidental release to the environment, when exposed to light, Modified Small Vinyl Ester will polymerise to an extremely stable polymer binding all Modified Small Vinyl Ester covalently in the polymer matrix that is highly insoluble in water. The polymer matrix has very low bioavailability to organisms in water. Direct and indirect exposure of water is assessed to be negligible and long-term effects in aqueous species are judged to be unlikely.
Conclusion on classification
Modified Small Vinyl Ester is not classified for the environment. For GHS, the Safety Net Classification (Chronic Category 4) was considered not to be applicable. According to CLP, no safety net classification is required if other scientific evidence exists showing classification to be unnecessary. Such evidence includes chronic toxicity NOECs > water solubility or > 1 mg/L. The only chronic data available is the algae test. In this test, the NOEC based on growth rate is 10 mg/L. The concentration of BisGMA at 10 mg/L Modified Small Vinyl Ester is above its water solubility limit of 0.42 mg/L. The analytical TWA concentration of Monomaleic acid of BisGMA at a nominal Modified Small Vinyl Ester concentration of 10 mg/L is 1.2 mg/L (18% of 6.7 mg/L which is the TWA concentration of Modified Small Vinyl Ester at 10 mg/L) This is above 1 mg/L. Therefore it is concluded that no Chronic Category 4 classification is required.
