Description of key information
Viscosity data are available for 3 proprietary streams within this category, with kinematic viscosity ranging from 1.11 to 1.9 mm2/s at 20°C and dynamic viscosity
ranging from 1.71 to 2.37 mPa.s at 20°C. Viscosity was also measured for 7 lead registrant streams in 2018 and the values ranged from 0.95 to 3.03 mm2/s at 40°C.
Key value for chemical safety assessment
- Viscosity:
- 1.9 mm²/s (static)
- at the temperature of:
- 20 °C
