Reference
Endpoint:
viscosity
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
Please refer to the attached QM(P)RF documents
Principles of method if other than guideline:
The result was obtained using an appropriate QSAR method (see attached QMRF and QPRF for details).

The model for viscosity has been developed for, and applies specifically to linear siloxane compounds. It is a linear regression based model with the normal boiling point of the substance as the single descriptor.
Temp.:
20°C
Parameter:
kinematic viscosity (in mm²/s)
Value:
0.7
Conclusions:
Akinematic viscosity value of 0.7 mm²/s at 20°C has been determined for the substance using an appropriate estimation method. The result is considered reliable.

Description of key information

Viscosity: 0.7 mm²/s at 20°C (kinematic) (QSAR)

Key value for chemical safety assessment

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

Additional information

A predicted kinematic viscosity of 0.7 mm²/s at 20°C was obtained for the substance using a validated QSAR estimation method. The result is considered to be reliable.
