Description of key information

Viscosity [octamethylcyclotetrasiloxane]: 1.6 mm2/s at 20°C (QSAR)

Key value for chemical safety assessment

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

Additional information

There is no reliable measured viscosity value for the substance. A predicted kinematic viscosity of 1.6 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. This value is supported by kinematic viscosity values of 2.3 - 2.6 mm2/s at 20 - 25°C which were reported for the substance in secondary sources to which reliability could not be assigned.
