Kinematic density calculated using Density 0.992

Conclusions:
The substance is considered to be sufficiently viscous to avoid the requirement for classification as aspiration hazard.

Description of key information

Measured over a range of temperatures between ca 0 C to 50 C.

Kinematic viscosity calculated using density of 0.992 based on static viscosity of 524 mPa S

Key value for chemical safety assessment

Viscosity:
524 mPa · s (dynamic)
at the temperature of:
40 °C

Additional information

The kinematice viscosity of 532 mm2/s at 40 C greater than the limit for classification as aspiration toxic material.
