PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

2'-hydroxyacetophenone (CAS 118-93-4) was experimentally found to be readily biodegradable (according to OECD criteria) and does, therefore, not fulfil the P/vP criteria. The measured log Kow indicates no potential for bioaccumulation; therefore, the substance is not B/vB. The substance is not toxic (not T) since the lowest chronic value is >> 0.01 mg/L and it holds no relevant classification.

In conclusion, 2'-hydroxyacetophenone is assessed to neither fulfill the PBT criteria (not PBT) nor the vPvB criteria (not vPvB).
