Description of key information

The endpoint is waived: The substance has no explosive properties because it is not classified as Organic Peroxide Type B.

1,1,4,4-tetramethylbutane-1,4-diyl bis(2-ethylperoxyhexanoate) is an  Organic Peroxide, Type C.

Key value for chemical safety assessment

non explosive

Additional information

Reference CLP regulations and UN Recommendations on the Transport of Dangerous Goods, 16th revised edition, Section also ECHA guidance on the application of the CLP criteria, section 2.14.

See supporting study: 13052-09-0, Explosiveness, Haisma, 1989, SS

1,1,4,4-tetramethylbutane-1,4-diyl bis(2-ethylperoxyhexanoate) is insensitive to shock.

Justification for classification or non-classification

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.See endpoint 4.13 Flammability.
