Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information

Substance has no explosive properties because it is not classified as Organic Peroxide Type B (reference CLP regulations 2.15.2.2 and UN Recommendations on the Transport of Dangerous Goods, 17th revised edition, Section 2.5.3.2.4.
See also ECHA guidance on the application of the CLP criteria, section 2.14

non explosive

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 into one of the seven categories “Type A to G” is dependent on its detonation, thermal explosion and deflagrating properties, its response to heating and the concentration [and the type of diluent added to desensitize the substance.]

The classification is given by the decision logic of the CLP regulation, Annex I, Figure 2.15.1.

Justification for classification or non-classification

The substance has no explosive properties because it is officially classified as Organic Peroxide Type C.
