Description of key information

Vapour Pressure [2,4,6-trimethyl-2,4,6-tris(3,3,3-trifluoropropyl)cyclotrisiloxane]: 88 Pa at 25°C (OECD 104)

Key value for chemical safety assessment

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

Additional information

Measured vapour pressures of 75.6 Pa and 88 Pa at 20°C and 25°C were determined for the substance using the static method of OECD 104 and in compliance with GLP. The result is considered to be reliable.

Predicted vapour pressure values of 2.5E-04 Pa and 1.3 Pa are estimated for the intermediate degradation product (

1,5-dihydroxy-1,3,5-trimethyl-1,3,5-tris(3,3,3-trifluoropropyl)trisiloxane) and ultimate degradation product ( 3,3,3-trifluoropropylmethysilanediol) respectively.
