Description of key information

The substance has no explosive properties based on the evaluation of its structural features. Also, the oxygen balance of the substance was calculated as -242%, which is less than the commonly accepted cut-off value of -200% for potentially explosive substances. According to this, 4,4’-Isopropylidenediphenol, propoxylated (BPA+2PO) is considered to pose no risk for explodability.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Evaluation of the structural features of the substance revealed that it does not contains any chemically instable or highly energetic groups that might lead to an explosion. Therefore, the substance is not expected to be explosive under the influence of flame or to be more sensitive to shock and friction than m-dinitrobenzene.

Justification for classification or non-classification

Based on the above mentioned result, classification according to the CLP Regulation (EC) No. 1272/2008 and the Dangerous Substance Directive 67/548/EC is not necessary.
