Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The dynamic viscosity of the liquid form of o-cresol is 3.06 mPa s at 50°C.

Key value for chemical safety assessment

Additional information

Determination of the viscosity at 20°C is technically not feasible. At 20°C o-cresol is crystalline solid and

has a melting point of 31°C. Below that temperature the substance is solid. Determination of the viscosity of solids is not possible according to OECD guideline 114. As the substance is used as a liquid above its melting point, a value at 50°C is presented.
