Description of key information

Viscosity [1,1,1,3,5,5,5-heptamethyl-3-[(trimethylsilyl)oxy]trisiloxane]: 1.3 mm2/s (QSAR)

Key value for chemical safety assessment

Viscosity:
1.3 mm²/s (static)
at the temperature of:
20 °C

Additional information

A predicted kinematic viscosity of 1.3 mm²/s at 20°C was determined for the substance using a validated QSAR estimation method. The result is considered to be reliable and selected as key study. In a secondary source to which reliability could not be assigned, a limit kinematic viscosity value of <10 cSt (mm²/s) at 25°C was reported for the substance.
