Applicant's summary and conclusion
- Conclusions:
- The kinematic viscosity of Tea Tree Oil was found to be 2.86 mm2/s at 20°C and 1.71 mm2/s at 40°C.
The dynamic viscosity of Tea Tree Oil was found to be 2.54 mPa/s at 20°C and 1.52 mPa/s at 40°C.
Kinematic viscosity data meet CLP criteria for classification of Tea tree oil as an aspiration hazard, Asp. Tox. 1 (H304: May be fatal if swallowed and enters airways). - Executive summary:
A GLP-compliant study was conducted in accordance with OECD Method 114 to determine the viscosity of Tea Tree Oil in triplicate at 20°C and 40°C using a reverse flow viscometer.
The dynamic viscosity of Tea tree oil was found to be 2.54 mPa/s at 20°C and 1.52 mPa/s at 40°C. Kinematic viscosity was 2.86 mm2/s at 20°C and 1.71 mm2/s at 40°C.
The kinematic viscosity data meet CLP criteria for classification of Tea tree oil as an aspiration hazard, Asp. Tox. 1 (H304: May be fatal if swallowed and enters airways).
