Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The classification of organic peroxides into one of the seven categories “Types A to G” is given in the decision logic in Figure 2.15.1 of CLP, based on the test series A to H, as described in the part II of the UN-MTC. The substance is classified as Organic Peroxide Type D, Liquid, 3115.
Key value for chemical safety assessment
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 “Types A to G” is dependent on its detonation, thermal explosion and deflagrating properties, its response to heating and the concentration.
Justification for classification or non-classification
Based on the results of the UN-MTC tests (below) and the decision logic, bis(3,5,5-trimethylhexanoyl) peroxide is classified as "Organic Peroxide Type D".
