Applicant's summary and conclusion
- Interpretation of results:
- Category 3 (flammable liquids) based on GHS criteria
- Conclusions:
- According to the variability of the sample due to fact that it is an UVCB (essential oil) the flash point of the test item was in the worst case 58 °C ± 1 °C.
- Executive summary:
The flash point of the test substance was determined under ISO 11018 method of 1997.
The flash point is below the classification thresholds of 60°C of the CLP regulation 1272/02008. Therefore the susbstance is classified as flammable liquids category 3.
