Description of key information
Additional information
The registered substance hydrolyses to [3-(2,3-epoxypropoxy)propyl]silanetriol and methanol, with a hydrolysis half-life of less than 12 hours. Therefore, the environmental hazard assessment, including sediment and soil compartments due to water and moisture being present, is based on the properties of the silanol hydrolysis product in accordance with REACH guidance for Chemical Safety Assessment. [3-(2,3-Epoxypropoxy)propyl]silanetriol is the hydrolysis product relevant to conventional REACH Chemical Safety Assessment.
[3-(2,3-Epoxypropoxy)propyl]silanetriol is susceptible to further hydrolysis reactions and the final silanol hydrolysis product is 3-[3-(trihydroxysilyl)propoxy]propane-1,2-diol.
3-[3-(Trihydroxysilyl)propoxy]propane-1,2-diol is the final product of hydrolysis reactions under the normal range of conditions of pH and temperature. However, other biotic or abiotic reactions may proceed over longer time-scales 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.
