PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB
Justification:

Bis(2-ethylhexyl) peroxydicarbonate undergoes immediate hydrolytical degradation in contact with water. Any possibility for exposure of aquatic organisms to bis(2-ethylhexyl) peroxydicarbonate can therefore be excluded. The major degradation product formed during hydrolysis is 2-ethylhexan-1-ol. PBT properties have therefore been evaluated for this substance.

Bis(2-ethylhexyl) peroxydicarbonate has further been demonstrated to be readily biodegradable. Any degradation products formed during hydrolysis (in particular 2-ethylhexan-1-ol) are considered to be themselves sufficiently rapidly degraded as not to require further assessment. Therefore, it can be concluded that bis(2-ethylhexyl) peroxydicarbonate including its hydrolytical degradation products is not persistent (not P, not vP).

Any other degradation products that may be formed during hydrolysis do not require specific assessment, since they are themselves rapidly degraded.

Neither bis(2-ethylhexyl) peroxydicarbonate nor its degradation products have PBT properties. Specifically, the major degradation product 2-ethylhexan-1-ol is not liable to bioaccumulate, nor does it fulfil toxicity criteria. For details please refer to the individual records in this section.
