Description of key information
The dynamic viscosity of the substance is 1.47 mPa*s at 20°C and 0.95 mPa*s at 40°C.
The kinematic viscosity o the substance is 1.73 mm²/s at 20°C and 1.15 mm²/s at 40°C.
Key value for chemical safety assessment
- Viscosity:
- 1.47 mPa · s (dynamic)
- at the temperature of:
- 20 °C
Additional information
A GLP study was conducted (BASF 11L00464) in accordance with the OECD Guideline for the Testing of Chemicals 114, Viscosity of liquids.
The kinematic viscosity was measured by a capillary viscosimeter. The dynamic viscosity was calculated by the equation n = v * p (p is density).
The dynamic viscosity of the substance was determined to be
1.47 mPa*s at 20°C and 0.95 mPa*s at 40 °C and
the kinematic viscosity of the substance was determined to be
1.73 mm²/s at 20°C and 1.15 mm²/s at 40°C.
