PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

Although α-methyl-1,3-benzodioxole-5-propionaldehyde (HLF) fulfills the criteria for toxicity (T), it does not fulfill the criteria for persistent (P) or very persistent (vP) and bioaccumulation (B) or very bioaccumulative (vB), and therefore, it is not classified as either a PBT or vPvB substance (see ECHA guidance ‘Part C: PBT/vPvB assessment’ , June 2017).
