Key result
Flash point:
45.5 °C
Atm. press.:
101 kPa

Atmospheric pressure: 101.0 kPa

Determination 1: 46.0°C

Determination 2: 45.0°C

The mean flash point was determined to be 45.5 ± 1 °C.

Interpretation of results:
Category 3 (flammable liquids) based on GHS criteria
Conclusions:
The substance is classified as Flammable Lliquid (cat.3) according to Regulation (EC) N°1272/2008 (CLP) criteria.
Executive summary:

The flash point of the test substance was measured according to EU A9 guideline, using a Pensky-Martens apparatus. Determination was performed in duplicate, and the mean value of 45.5°C was retained.

Executive summary:

The HSDB database provides, as secondary source, some physico-chemical properties. A flash point of 45°C is cited for limonene.

Description of key information

Crude quality: Flash point = 45.5°C. Expected to be similar for rectified quality.

The substance (both qualities) is classified as FLAMMABLE LIQUID (cat.3) according to Regulation (EC) N°1272/2008 (CLP) criteria.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
45.5 °C

Additional information

This endpoint is relevant for the classification regarding flammable properties.

An experimental study is available for the crude quality.

Literature data for the three major components shows that the FP of the oil is determined by the major component, not by the most flammable (cineole, FP ca 47 -48°C, limonene, FP ca 45°C, and alpha-pinene, FP ca 33°C).

Therefore, for the rectified quality containing less alpha-pinene and more cineole, the Flash Point is expected to be similar. Moreover, regarding the classification thresholds (all above components in the same category), the margin of safety is considered sufficient for addressing both qualities in the same category, no higher hazard is anticipated.

The experimental result will be retained as key data for purpose of CSA.

It should be noted that due to UVCB nature of the substance, batch variations are expected.
