Endpoint:
flammable gases
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:
flammable liquids: obsolete as covered by section 'Flash point'
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:
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
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:
pyrophoric 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
Endpoint:
self-heating substances / mixtures
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted for organic peroxides
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 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

Description of key information

Flammability in contact with water:

Based on the molecular structure as well as experience in handling and use, the substance shows no water reactive properties.

Pyrophoric properties:

Based on the molecular structure as well as experience in handling and use the substance shows no pyrophoric properties.

Self-heating substance

According to Guidance on information requirements and chemical safety assessment, R7a, Endpoint specific guidance, R.7.1.10.7, the UN Test method N.4, for self-heating substances and mixtures does not need to be conducted as the substance is classified as organic peroxide.

Self-reactive substance

According to Guidance on information requirements and chemical safety assessment, R7a, Endpoint specific guidance, R.7.1.10.4, the UN test series A - H for self-reactive substances and mixtures, do not need to be conducted as the subsancse is classified as organic peroxide.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

According to chapter 2.15 of the CLP regulation, organic peroxides are thermally unstable substances or mixtures, which can undergo exothermic self-accelerating decomposition. In addition, they can have one or more of the following properties:

(i) be liable to explosive decomposition;

(ii) burn rapidly;

(iii) be sensitive to impact or friction;

(iv) react dangerously with other substances.

An organic peroxide is regarded as possessing explosive properties when in laboratory testing the mixture (formulation) is liable to detonate, to deflagrate rapidly or to show a violent effect when heated under confinement.

The classification of an organic peroxide in one of the seven categories “Types A to G” is dependent on its detonation, thermal explosion and deflagrating properties, its response to heating and the concentration

Flammability in contact with water:

Based on the molecular structure as well as experience in handling and use, the substance shows no water reactive properties.

Pyrophoric properties:

Based on the molecular structure as well as experience in handling and use the substance shows no pyrophoric properties.

Self-heating substance

According to Guidance on information requirements and chemical safety assessment, R7a, Endpoint specific guidance, R.7.1.10.7, the UN Test method N.4, for self-heating substances and mixtures does not need to be conducted as the substance is classified as organic peroxide.

Self-reactive substance

According to Guidance on information requirements and chemical safety assessment, R7a, Endpoint specific guidance, R.7.1.10.4, the UN test series A - H for self-reactive substances and mixtures, do not need to be conducted as the subsancse is classified as organic peroxide.

Justification for classification or non-classification

Based on the study results, the molecular structure and experience in handling and use, the substance is not classified and labelled as flammable, flammable in contact with water, pyrophoric, self-reactive substance and self-heating substance according to Regulation (EC) No 1272/2008 (CLP).
