Endpoint:
pyrophoric liquids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
the study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In accordance with section 1 of REACh Annex XI, study for pyrophoric properties is deemed unnecessary based on the chemical structure of the major components (cineole, limonene, alpha-pinene) that do not fall into critical categories described in ECHA guidance, and based on the experience in handling, testing and use of the substance.
Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied
the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In accordance with section 1 of REACh Annex XI, study for flammability if contact with water is deemed unnecessary based on the chemical structure of the major components (cineole, limonene, alpha-pinene) that do not fall into critical categories described in ECHA guidance, and based on the experience in handling, testing and use of the substance.
Endpoint:
flammable solids
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In accordance with section 2 of REACh Annex XI, flammability studies relevant for classification criteria do not apply to liquids. Please refer to flash point under 4.11.

Endpoint:
self-heating substances / mixtures
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid
the study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
According to ECHA Guidance on the Application of the CLP Criteria (v4.1, June 2015, §2.11.4.2.), the phenomenon of self-heating generally applies only to solids. The surface of liquids is not large enough for reaction with air and the test method (UN N4) is not applicable to liquids. Therefore liquids, unless adsorbed, are not classified as self-heating.
Moreover, the major components do not contain metals, which are typically self-heating substances.
Reason / purpose:
data waiving: supporting information

Description of key information

Crude quality: Flash point = 45.5°C. Expected to be similar for rectified quality, with sufficient margin of safety for addressing in the same classification category.

Not flammable if contact with air or water (waived).

No self-heating anticipated for liquids (waived).

Key value for chemical safety assessment

Flammability:
flammable

Additional information

As the substance is a liquid, the relevant test for flammable properties is the flash point measurement. A reliable experimental study is presented under point 4.11.

Based on the chemical structure of the major components and experience, no flammable properties are anticipated if contact with air or water, or no self-heating, therefore specific studies were deemed unnecessary.

Justification for classification or non-classification

According to Regulation (EC) No.1272/2008 criteria, the measured flash point lies between the threshold values of 23 and 60°C, therefore the substance is classified as FLAMMABLE LIQUID category 3 (H226).

The three major components being in the same category, and the quality tested being a worst-case with regard to the content of the most flammable component, the margin of safety is considered sufficient for adressing both eucalyptus oil qualities in the same category, no higher hazard is anticipated.
