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 WAIVINGIn accordance with section 1 of REACh Annex XI, study for flammability if contact with water is deemed unnecessary based on the chemical structure that does not fall into critical categories described in ECHA guidance, and based on the experience in handling, testing and use of the substance.

The chemical structure does not contain any group associated with high flammability when coming in contact with water as given in the literature. There is also no such behaviour known by the manufacturer.

Auto ignition while coming in contact with water of the test item is not expected and therefore, the test item should be classified as Not a substance or mixture which, in contact with water, emit flammable gases, according to GHS criteria (rev.6 - 2015).

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 WAIVINGIn accordance with section 2 of REACh Annex XI, flammability study UN N1 relevant for classification criteria under 4.13 do not apply to liquids. Please refer to flash point under 4.11.
Reason / purpose:
data waiving: supporting information
Reason / purpose:
data waiving: supporting information
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 WAIVINGIn accordance with section 1 of REACh Annex XI, study for pyrophoric properties is deemed unnecessary based on the chemical structure that does not fall into critical categories described in ECHA guidance, and based on the experience in handling, testing and use of the substance.

Principles of method if other than guideline:
assessment of chemical structure
GLP compliance:
no

The chemical structure does not contain any group associated with pyrophoric properties nor are there any physical reasons like very high distribution or else. There is also no such behaviour known by the manufacturer.

Pyrophoric properties of the test item will not be expected and therefore the test item should be classified as Not pyrophoric liquid according to GHS criteria (rev.6 - 2015).

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
Justification for type of information:
JUSTIFICATION FOR DATA WAIVINGAccording 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 chemical structure does not contain metals, which are typically self-heating substances.

Description of key information

Flash point = 137°C (experimental)

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

No self-heating anticipated for liquids (waived).

Key value for chemical safety assessment

Flammability:
not classified

Additional information

As the substance is a liquid, the relevant test for flammable properties is the Flash Point measurement.

A fully reliable experimental study is presented under point 4.11.

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

Justification for classification or non-classification

According to Regulation (EC) No.1272/2008 (CLP) criteria, the measured flash point is above the threshold value of 60°C, therefore the substance is NOT considered as a flammable liquid.

According to UN Globally Harmonised System (GHS) criteria, the measured flash point is above the threshold value of 93°C, therefore the substance is NOT considered as a flammable liquid.
