PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT Assessment for 1,2,3-Propanetriol, homopolymer (CAS 25618-55-7) is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2012a).
Persistence
Based on the available data the test substance is readily biodegradable. Thus, the test substance is not considered to be P or vP.
Bioaccumulation
Based on its ready biodegradability and very low log Kow of -2, the substance is considered to have a very low bioaccumulation potential and therefore does not meet the Bioaccumulative (B) or very Bioaccumulative (vB) criterion.
Toxicity
1,2,3-Propanetriol, homopolymer (CAS 25618-55-7) is considered as not toxic. The substance is not acutely toxic to aquatic organisms. A chronic toxicity is not expected since the substance is not persistent and has a low potential for bioaccumulation. Furthermore the substance is not classified for specific target organ toxicity, carcinogenicity, mutagenicity or reproductive and developmental toxicity in mammals (see section 5.9). The criteria for “T” based on mammalian effects are therefore not met. Thus, the criteria set out in Annex XIII of Regulation (EC) No. 1907/2006 are not met and the substance is considered to be not T.
