- Viscosity:
- 1.77 mm²/s (static)
- at the temperature of:
- 20 °C
Additional information
A kinematic viscosity value of 1.77 mm2/s at 20°C was determined for the substance using a capillary viscometer (static) method and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable.
The key study is supported by a predicted kinematic viscosity value of 1.8 mm2/s at 20°C which was determined for the substance using a validated QSAR estimation method.
In an available secondary source to which reliability could not be assigned, a dynamic viscosity value of 2 mPa.s at 20°C was reported for the substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
