Administrative data

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
Justification for type of information:
Expert statement on explosive properties
Except for its unsaturated C=C double bond Ascorbyl Palmitate does not contain chemical groups indicating explosive properties.
The heat of decomposition (in the temperature range up to 400°C) corresponds to 'H = -285 J/g and therefore below the limit value of - >500 J/g for potentially explosive materials. The calculated oxygen balance (OB) for Ascorbyl Palmitate is OB = -216 and therefore below the limit value of OB = -200 for potentially explosive materials. Thus it can be concluded beyond a reasonable doubt that Ascorbyl Palmitate is not a potential explosive and does not have a potential for rapid energy release. Therefore Ascorbyl Palmitate is not to be classified as explosive material and no experimental determination according to the EC test guideline A.14 has to be performed. Nevertheless, this judgment is with respect to classification and does not necessarily mean that any processing hazards can be excluded.
