Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
