Additional information
Conclusion on classification
It is proposed that trichloro(methyl)silane should not be classified in the EU for acute or chronic toxicity on the grounds that appropriate read-across indicates that it is not toxic at an initial loading rate of the substance of 100 mg/l.
The rapid hydrolysis of the substance and the low Log Kow of the silanol hydrolysis product indicate that the classification R53 should not apply.
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.
