Additional information
Conclusion on classification
It is proposed that dichloro(methyl)silane should not be classified in the EU for acute or chronic toxicity on the grounds that read-across from a close structural analogue of the silanol hydrolysis product indicates that the substance would not be toxic at a loading rate of 100 mg/l.
The rapid hydrolysis of the substance and the low Log KOWof the silanol hydrolysis product indicate that the classification R53 should not apply.
Hydrogen chloride is included in Annex I of Directive 67/548/EEC and does not require classification for 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.
