Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- 2-Ethylhexanoic acid
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Reference substance:
- 2-Ethylhexanoic acid
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The substance is assessed to be readily biodegradable (see IUCLID Ch. 5.2.1).
As the substance is concluded to be readily biodegradable (according to OECD criteria), it should not be considered as potentially P/vP. The substance is not B/vB based on an experimentally derived log Kow 2.7 at 23 °C, pH 4.7 (BASF AG, rep. No.: BRU 88.174, 1988). The estimated Log Kow for the uncharged molecule is 2.96 (EPI Suite v4.11, KOWWIN v1.68, BASF 2020).In addition, several QSAR calculations (calculated BCF values range between 1.93 L/kg and 112.5 L/kg, BASF SE 2020) indicate no significant potential for bioaccumulation. However, due to the results of relevant mammalian toxicity studies (see CSR chapter 5. Human Health Hazard Assessment), the substance has to be regarded as toxic (T).
In conclusion, the substance is not to be considered as a PBT/vPvB substance.
Reference
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.
