Description of key information
The test substance farnesene was tested following ASTM method D7042 (Standard Test Method for Dynamic Viscosity and Density of Liquids by
Stabinger Viscometer and Kinematic Viscosity by Calculation). The dynamic viscosity was determined to be 1.788 mPa .S at 20°C and the kinematic viscosity was calculated using the density (0.83 g/cm3) to be 2.15 mm2/s at 20 °C.
Key value for chemical safety assessment
- Viscosity:
- 1.788 mPa · s (dynamic)
- at the temperature of:
- 20 °C
Additional information
Based on the following classification criteria, the test substance is to be classified as an aspiration hazard category 1. Aspiration category 1 : Substances known to cause human aspiration toxicity hazards or to be regarded as if they cause human aspiration toxicity hazard. A substance is classified in Category 1: (a) based on reliable and good quality human evidence or (b) if it is a hydrocarbon and has a kinematic viscosity of 20.5 mm 2/s or less, measured at 40 °C. The study was done at 20 °C and not 40 °C. Because viscosity decreases with increasing temperature the classification of aspiration category 1 is justified.
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).
