Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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

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.
