Description of key information
Vapour pressure [registration substance]: 390 Pa at 20°C [OECD 104]
Key value for chemical safety assessment
- Vapour pressure:
- 390 Pa
- at the temperature of:
- 20 °C
Additional information
A vapour pressure value of 390 Pa at 20°C was determined for the registration substance in a reliable study conducted according to an appropriate test protocol.
The registration substance is a multi-constituent substance containing four constituents, decamethyltetrasiloxane (L4, CAS 141-62-8), dodecamethylpentasiloxane (L5, CAS 141-63-9), hexamethyldisiloxane (HMDS, CAS 107-46-0) and octamethyltrisiloxane (L3, CAS 107-51-7). The environmental hazard assessment is based on the properties of the constituents, therefore data for each constituent are also reported.
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.
