- Conclusions:
- The dynamic viscosity of DL-Menthol is 17 mPa*s at 40°C.
- Executive summary:
The determination of the dynamic viscosity is based on the following guidelines: DIN 53019, this industry norm corresponds to OECD Guidelines for Testing of Chemicals, Section 1 – Physical-Chemical Properties No. 114 "Viscosity of Liquids" (adopted May 1981).
The dynamic viscosity of DL-Menthol is 17 mPa*s at 40°C.
Reference
Dynamic viscosity at 40 °C: 17.36 / 17.39 mPa s mean value: 17 mPa s
Description of key information
The dynamic viscosity of DL-Menthol was determined as 17 mPa*s at 40 °C according to DIN 53019, which corresponds to OECD Guidelines for Testing of Chemicals, Section 1 - Physical-Chemical Properties No. 114 "Viscosity of Liquids" (adopted May 1981).
Key value for chemical safety assessment
- Viscosity:
- 17 mPa · s (dynamic)
- at the temperature of:
- 20 °C
Additional information
The physical state of the substance at room temperature is solid. Nevertheless, the substance is used as hot melt and therefore, the viscosity was determined.
Determination of the viscosity at 20 °C is technically not feasible. At 20 °C DL-Menthol is crystalline solid and has a melting point of 41-43°C. 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 40 °C is presented.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
