- Name:
- Methyl Isomyl Ketone
- Type of composition:
- boundary composition of the substance
- State / form:
- liquid
- Reference substance:
- Methyl Isomyl Ketone
- PBT status:
- the substance is not PBT / vPvB
- Justification:
According to REACH VO 1907/2006, Section 1 Annex XIII, an organic substance is only regarded as a PBT/vPvB (Persistent, Bioaccumulative and Toxic/very Persistent and very Bioaccumulative) when test data show that the inherent properties of the substance fulfil the criteria for P, B and T. In case of 5-methylhexan-2-one, the substance does fulfill the T-criterion (Classificaiton as Repro Cat. 2), but not the P- or B-criterion, as it has been shown to be readily biodegradable and has a partition coefficient < 4.5. Therefore, the substance is "not PBT" and "not vPvB".
