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

Description of key information

The test item molecule contains groups that are able to contribute to the explosive property. Therefore, according to "Guidance on information requirements and chemical safety assessment", Chapter R.7a: Endpoint specific guidance, R. (ECHA, May 2008), the oxygen balance (OB) for the test item molecule (CxHyOz) was calculated with the result OB: -293.7.

Since the oxygen balance is less than -200, the substance should not have explosive properties.

Key value for chemical safety assessment

non explosive

Additional information

Justification for classification or non-classification

With an OB of -293.7, 2 -ethylhexylal is not classified as explosive.
