Endpoint:
explosive properties of explosives
Data waiving:
other justification
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

Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In accordance with REACH Regulation (EC) No. 1907/2006 Annex VII, column 2 section 7.11 the study does not need to be conducted based on structural assessment of the substance. Although the substance constituents contains groups associated with explosive properties alerts (epoxide groups). the calculated oxygen balance for each constituent is < - 200 (Actual = -256.6). Furthermore, handling and use confirm that the substance does not have explosive properties. According to ECHA Guidance on Information Requirements and Chemical Safety Assessment (Chapter R.7a: Endpoint Specific Guidance, R.7.1.11, July 2017) the study does not need to be conducted.
