Description of key information

The endpoint is waived: The substance is already classified as explosive. The substance has explosive properties because it is 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.

Key value for chemical safety assessment

Explosiveness:
explosive

Additional information

The peroxide formulations with concentrations > 90% are classified as peroxides with explosive properties.

The concentrations up to and including 90% are not classified as peroxides with explosive properties.

Justification for classification or non-classification

Di-tert-butyl 3,3,5-trimethylcyclohexylidene diperoxide is classified as a peroxide Type B.(reference CLP regulations 2.15.1.2, 2.15.2.2 and UN Recommendations on the Transport of Dangerous Goods, 16th revised edition, Section 2.5.3.2.4).

See also ECHA guidance on the application of the CLP criteria, section 2.14. The classification of organic peroxides into one of the seven categories of “Types A to G” is given in decision logic Figure 2.15.1 of CLP, based on the test series A to H, as described in the Part II of the UN-MTC.
