PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT Assessment for decanoic acid is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2012).
Persistence
Decanoic acid (CAS 334-48-5) is readily biodegradable according to OECD criteria (62 – 105 % after 30 d). Thus, the substance does not meet the screening criterion for persistence and is not considered to be persistent (P) or very persistent (vP).
Bioaccumulation
Decanoic acid has a log Pow between 4.02 and 4.09 (≤ 4.5) at room temperature and neutral pH. Thus, the substance does not meet the screening criterion for bioaccumulation and is not considered to be bioaccumulative (B) or very bioaccumulative (vB).
Toxicity
Long-term toxicity testing with Daphnia magna resulted in an NOEC (21 d) of 0.2 mg/L (≥ 0.01 mg/L). Moreover, the substance is not classified as carcinogenic, mutagenic or toxic for reproduction according to Regulation (EC) No. 1272/2008 (7th ATP). 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
