Description of key information

Viscosity (decamethyltetrasiloxane): 1.3 mm2/s at 20°C (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 (1.2 mPa.s) at 20°C was determined for the substance using a validated QSAR estimation method. The result is considered reliable and selected as key study. In other secondary sources to which no reliability could be assigned, viscosity values of 1.5 cSt and 1.7 mm²/s were reported for the substance.
