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
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
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

Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
27/06/2012
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
no
GLP compliance:
yes (incl. QA statement)

From the preliminary screening test the sample was seen to briefly ignite and therefore no further testing is required.

As the material was moisture-sensitive and testing under relative low humidity conditions was not possible, the testing performed was carried out as quickly as possible. The material was not observed to undergo physical changes caused by atmospheric moisture.

Initially on heating, the sample melted to an off-white liquid and ignited with a pale blue flame when in contact with the ignition source. No propagation of this reaction was observed.

Interpretation of results:
non flammable
Conclusions:
It has been determined that Amides, C12-18 (even-numbered), N-[3-(dimethylamino)propyl], N'-oxides should not be classified as a readily combustible solid of UN Class 4, Division 4.1. No propagation of this reaction was observed.

Description of key information

It has been determined that the test substance should not be classified as a readily combustible solid of UN Class 4, Division 4.1. Flammability, pyrophoric properties and water reactivity studies are not required based on Section 1 of REACH Annex XI. Based on the chemical structure, it is concluded that the test substance is not flammable in contact with water, and does not show pyrophoric properties. Furthermore, it is not considered to be a flammable liquid nor self-heating as the latter only applies to solids. 

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

Initially on heating, the sample melted to an off-white liquid and ignited with a pale blue flame when in contact with the ignition source. No propagation of this reaction was observed. It has been determined that the test substance should not be classified as a readily combustible solid of UN Class 4, Division 4.1.
