Key value for chemical safety assessment
Effects on fertility
Additional information
The substance is an on-site intermediate. Therefore, exposure will be minimal, and reproduction toxicity information is not necessary. Disilane, chloro Me derivs.is expected to hydrolyse rapidly in contact with water to give hydrogen chloride and, initially,the silanol derivatives of the three main constituents, and further hydrolyse to methylsilanetriol and dimethylsilanediol. The reproductive toxicity of these substances, and risk characterisation at far higher exposure than is expected for this submission substance, have been assessed in the CSRs of the REACH-registered chlorosilane precursors trichloro(methyl)silane (CAS 75-79-6, EC200-902-6) and dichloro(dimethyl)silane (CAS 75-78-5, EC200-901-0). These substances were found to be not toxic to reproduction.

Additional information
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.
