Description of key information

Viscosity [Fatty alcohols C16 – C18 (even numbered), branched and linear]: 30.79 mm2/s at 40°C (ISO 3104), 68 mPa · s at 20°C (ISO 2555)

Key value for chemical safety assessment

Viscosity:
30.79 mm²/s (static)
at the temperature of:
20 °C

Additional information

A measured kinematic viscosity value of 30.79 mm2/s at 40°C was determined for the substance in accordance with ISO 3104. Similarly, a dynamic viscosity of 68 mPa.s (calculated kinematic value of 79.8 mm2/s) at 20°C was determined for the substance in accordance with ISO 2555. The results are considered to be reliable and selected as key studies. In a secondary source to which no reliability could be assigned, dynamic viscosity value of 30 mPa s at 25°C was reported for the substance.
