Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Link to relevant study record(s)
- 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 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.
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.
Justification for classification or non-classification
In accordance with Annex I Section 2.2, Section 2.3, Section 2.6, Section 2.7, Section 2.9, Section 2.10 Section 2.11, Section 2.12 of Regulation (EC) No 1272/2008, as amended for the seventeenth time in Regulation (EU) 2022/692, and UN GHS Rev 9 (2021) the test item has not to be classified as readily combustible solid in Class 4 Division 4.1, flammable liquid in Class 3, self-heating substance in Class 4 Division 4.2, substances which in contact with water emit flammable gases in Class 4 Division 4.3, pyrophoric liquid, pyrophoric solid in Class 4 Division 4.2, flammable gases in Class 2 or as flammable aerosol in Class 2.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
