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

Interpretation of results:

other: EU GHS criteria not met

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

Description of key information

Flammability:

2 -Pyrrolidone is a not easily flammable liquid (GESTIS, 2010).

Flammability, contact with water:

The test material does not contain structural components associated with pyrophoricity and/or flammability on contact with water mentioned in the Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, chapter R.7.1.10.3, page 123. Therefore, it can be concluded that the test material exhibit no risk for pyrophoricity and/or flammability on contact with water. No study is required.

Flammability, pyrophoric liquids:

The study is scientifically not necessary, because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and the test material does not contain structural components associated with pyrophoricity mentioned in the Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, chapter R.7.1.10.3, page 123. Therefore, it can be concluded that the test material exhibit no risk for pyrophoricity.

Flammability, self-heating substances:

The study is scientifically not necessary, because the substance is completely molten at 160 °C. The substance is a liquid.

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

2-Pyrrolidone possess a slight fire potential, when exposed to heat or flame and can react with oxidizing materials (Sax, N.I., 1979).

Justification for classification or non-classification

The available studies do not reveal 2 -pyrrolidone to be a flammable liquid. As such classification is not warranted according to the criteria of EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.

Based on the physical state, the structural elements and the melting point the substance has neither to be classified as flammable in contact with water, nor as pyrophoric liquid, nor as self-heating substance.
