Description of key information

Vapour pressure [3,3-bis[(dimethylvinylsilyl)oxy]-1,1,5,5-tetramethyl-1,5-divinyltrisiloxane]: <10 Pa at 25 - 101°C (OECD 104)

Key value for chemical safety assessment

Vapour pressure:
10 Pa
at the temperature of:
25 °C

Additional information

A measured vapour pressure of <10 Pa at 25 - 101°C was determined for the substance using the static method in accordance with OECD 104 and in compliance with GLP. The result is considered to be reliable and selected as key study. This value is supported by a predicted vapour pressure of 0.22 Pa at 25°C which was determined using a validated QSAR estimation method. The supporting data are in agreement with the key data that the substance is a very low volatility substance.
