Key value for chemical safety assessment
- Viscosity:
- 5.58 mm²/s (static)
- at the temperature of:
- 40 °C
Additional information
A kinematic viscosity value of 5.58 mm²/s at 40°C was determined for octan-1-ol with the use of a capillary method in accordance with ASTM D445. The result is considered to be reliable and is used for assessment purposes.
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
