Executive summary:

Tetracosanol was determined according ASTM D 7042. The viscosity was determined to be 8.3 mPa*s at 80 °C.

Description of key information

The kinematic viscosity of tetracosan-1-ol is  10.4 mm ²/s and 8.3 mPa.s at 80°C.

Key value for chemical safety assessment

Viscosity:
10.4 mm²/s (static)
at the temperature of:
80 °C

Additional information

A kinematic viscosity value of 10.4 mm ²/s at 80°C was determined for tetracosan-1-ol using a relevant test method. The result is considered to be reliable.

Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols:

As chain length increases, kinematic viscosity increases. This is because molecular weight is higher and intermolecular forces in the substance are all higher.
