Description of key information
Additional information
The substance is a multi-constituent substance consisting mainly of trimethyl(octadecyloxy)silane and octadecan-1-ol. The substance is a waxy solid at room temperature with a melting point in the range -12.4°C to 52.2°C and a boiling point of 356oC at 101.3 kPa. The substance is subject to hydrolysis with an estimated half-life of around 15 hours at pH 7 and 25°C forming octadecan-1-ol and trimethylsilanol. Thus octadecan-1-ol is both a constituent of the substance and a hydrolysis product.
The trimethyl(octadecyloxy)silane constituent has an estimated vapour pressure of 0.0027 Pa at 25°C and estimated log Kow of 9 and an estimated water solubility of 2.2E-06 mg/L. The constituent octadecan-1-ol has a vapour pressure of 0.00036 Pa at 25°C, an estimated log Kow of 8.22 and a water solubility of 1.1E-03 mg/L.
The auto-ignition temperature of the registered substance is 233°C at 1013 hPa and the substance is non-flammable and non-explosive.
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.
