- Endpoint:
- viscosity
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 19 October 2022 - 21 October 2022

- Temp.:
- 20°C
- Parameter:
- kinematic viscosity (in mm²/s)
- Value:
- ca. 13.8
- Conclusions:
- The viscosity of Longifolene was measured at shear rates of 73 to 245 sec-1 at 20°C and 40°C.
The test item was found to be Newtonian in its flow behaviour. Under the specified test conditions, the measured dynamic viscosity was 13.0 mPa.s at 20ºC and 7.4 mPa.s at 40ºC. The kinematic viscosity was calculated as 13.8 mm2/s at 20ºC and 7.9 mm2/s at 40ºC. - Executive summary:
The purpose of this study was to evaluate the viscosity of the test item, Longifolene.
The study was designed in accordance with accepted principles in order to meet the requirements of the OECD Guidelines for Testing of Chemicals and US EPA OCSPP Series 830 - Product Properties Test Guidelines.
The viscosity of Longifolene was measured at shear rates of 73 to 245 sec-1 at 20°C and 40°C.

Description of key information
Based on the CLP regulation as the Kinematic viscosity is less than 20.5mm2/s, Longifolene is classified as a category 1: Aspiration toxicity (H304: May be fatal if swallowed and enters airways)
Key value for chemical safety assessment
- Viscosity:
- 7.9 mm²/s (static)
- at the temperature of:
- 40 °C
