Reference
Endpoint:
explosive properties of explosives
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance contains chemical groups associated with explosive properties which include oxygen, but the calculated oxygen balance is less than - 200
Interpretation of results:
GHS criteria not met

Description of key information

In accordance with the column 2 of REACH Annex VII, the study does not need to be conducted if the substance contains chemical groups associated with explosive properties which include oxygen (organic peroxide) and the calculated oxygen balance is less than -200 (OB = -250.52).

Moreover, the 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, 16th revised edition, Section 2.5.3.2.4).

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Justification for classification or non-classification

In the CLP Regulation (EC) No.1272/2008, Organic peroxides are not classified as explosive, they are classified in a distinct hazard class which include the explosive properties (reference CLP Regulation 2.15).

[1,3-phenylenebis(1-methylethylidene)]bis[tert-butyl] peroxide is classified as Organic Peroxide Type D according to CLP Regulation (EC) No.1272/2008.
