Effects on fertility
Description of key information
There are no oral, inhalation or dermal reproductive toxicity studies available for 1,2 -bis[dichloro(methyl)silyl]ethane. Data waivers are in place for this endpoint (see attachment to data waiver for toxicity to reproduction).
Limited data are available regarding the reproduction and development of animals following oral, dermal or inhalation exposure to hydrogen chloride or hydrochloric acid, however, protons and chloride ions both exist as normal constituents of body fluid in animals, hence low concentrations of hydrogen chloride appear not to cause adverse effects in animals. Therefore hydrochloric acid would not contribute to any reproductive toxicity (fertility or developmental) effects at the dose levels tested.
Effect on fertility: via oral route
- Endpoint conclusion:
- no study available
Effect on fertility: via inhalation route
- Endpoint conclusion:
- no study available
Effect on fertility: via dermal route
- Endpoint conclusion:
- no study available
Effects on developmental toxicity
Description of key information
There are no oral, inhalation or dermal developmental toxicity studies available for 1,2 -bis[dichloro(methyl)silyl]ethane. Data waivers are in place for this endpoint (see attachment to data waiver for developmental toxicity).
Limited data are available regarding the reproduction and development of animals following oral, dermal or inhalation exposure to hydrogen chloride or hydrochloric acid, however, protons and chloride ions both exist as normal constituents of body fluid in animals, hence low concentrations of hydrogen chloride appear not to cause adverse effects in animals. Therefore hydrochloric acid would not contribute to any reproductive toxicity (fertility or developmental) effects at the dose levels tested.
Effect on developmental toxicity: via oral route
- Endpoint conclusion:
- no study available
Effect on developmental toxicity: via inhalation route
- Endpoint conclusion:
- no study available
Effect on developmental toxicity: via dermal route
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
The available data indicate that 1,2 -bis[dichloro(methyl)silyl]ethane
does not need to be classified for toxicity to reproduction (fertility or developmental toxicity) according to Regulation (EC) No 1272/2008.
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.
