Description of key information
Water solubility (substance): Not relevant
Water solubility (silanol hydrolysis product): 995 mg/L at 20°C
Key value for chemical safety assessment
Additional information
The requirement to test the substance for water solubility is waived becasue in contact with water the substance rapidly hydrolyses to form trimethylsilanol and hydrogen chloride. A water solubility of 995 mg/l for trimethylsilanol has been determined in a reliable study conducted according to an appropriate test protocol, and in compliance with GLP; this is assigned as the key study.
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.
