Description of key information
Kinematic Viscosity: 3.04 mm²/s at 20°C and 2.03 mm²/s at 40°C (capillary method)
Key value for chemical safety assessment
- Viscosity:
- 3.04 mm²/s (static)
- at the temperature of:
- 20 °C
Additional information
Kinematic viscosity values of 3.04 mm2/s at 20°C and 2.03 mm2/s at 40°C were determined for the submission substance according to the Ubbelohde capillary method. The results are considered to be reliable and are selected as key.
The key result is supported by a predicted kinematic viscosity of 2.4 mm2/s at 20°C, determined using a validated QSAR estimation method. The result is considered to be reliable.
In a secondary source to which reliability could not be assigned, a dynamic viscosity value of 3.0 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.
