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
According to REACh Annex XI / section 2, flammability study UN N1 relevant for classification criteria under 4.13 does not apply to liquids. Please refer to Flash Point under 4.11.
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
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 experience in handling and use of the substance and based on the chemical structure of known constituents of the substance that do not fall into critical categories described in ECHA guidance.
A review of the chemical structure of the known constituents suggests that there are no chemical groups present that would imply flammability on contact with water. In addition, no experience in handling and use of the registered substance has been reported, which could cast doubt on the NON-flammability if contact with water of the substance.
Therefore, the study was considered as unnecessary.
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 experience in handling, testing and use of the substance and based on the chemical structure of the known constituents of the substance that do not fall into critical categories described in ECHA guidance.
The tests performed on the substance and reported in this dossier showed that the substance clearly does not react with air. Moreover, a review of the chemical structure of the known constituents suggests that there are no chemical groups present in these constituents that would imply pyrophoric properties. Therefore, the study was considered as unnecessary.
Reason / purpose:
assessment report
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 substance is completely molten at 160°C
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
According to the Guidance on the Application of the CLP Criteria, v5.0 of July 2017, $ 2.11.4.2:
"the phenomenon of self-heating applies only to solids. The surface of liquids is not large enough for reaction with air and the test method is not applicable to liquids. Therefore liquids are not classified as self-heating…".
In addition,
"Substances or mixtures with a low melting point (< 160 °C) should not be considered for classification in this class since the melting process is endothermic and the substance-air surface is drastically reduced. However, this criterion is only applicable if the substance or mixture is completely molten up to this temperature."
Considering that the test item is described as a liquid with a freezing point < -20°C (see endpoints 4.1 and 4.2), no test to determine self-heating properties is required.

Description of key information

Flash Point = results on-going.

NOT a flammable solid (CLP/GHS) (waived).

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

NO self-heating properties anticipated (waived).

Key value for chemical safety assessment

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 (Study on-going).

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

Justification for classification or non-classification

Flash Point: study on-going (LAUS, 2019). Therefore, no classification is proposed according to Regulation (EC) N°1272/2008 (CLP criteria) and UN Globally Harmonized System (GHS criteria).

Based on the physical state of the substance (liquid), the evaluation of the Flammability of the substance according to UN Test N.1 was waived and no classification as self-heating substance is anticipated.
