PBT status:
the substance is not PBT / vPvB

The PBT Assessment for propylene dinonanoate (CAS 41395-83-9) is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2017).


Propylene dinonanoate (CAS 41395-83-9) is readily biodegradable (82 - 100% biodegradation after 28 d), as shown in studies conducted according to international guidelines. Thus, the substance does not meet the screening criterion for persistency and it is not considered to be P or vP.


The bioaccumulation assessment was not conducted for the substance since it is not persistent and according to ECHA Guidance on Information Requirements and Chemical Safety Assessment Chapter R.11: PBT/vPvB assessment (2017) further generation of information on bioaccumulation is only necessary, if the P/vP criterion is fulfilled for the substance.


Appropriate read across data showed no toxicity towards species from three trophic levels (fish, aquatic invertebrates and algae). Moreover, propylene dinonanoate (CAS 41395-83-9) is not classified according to the consolidated version of Regulation (EC) No. 1272/2008 (and further ATPs). Thus, the criteria set out in Annex XIII of Regulation (EC) No. 1907/2006 are not met and the test substance is not considered to meet the T criterion.

In conclusion propylene dinonanoate (CAS 41395-83-9) is not considered to be PBT/vPvB.
