Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The criteria given in the “Guidance on information requirements and chemical safety assessment, chapter R.11: PBT Assessment” (ECHA, 2017) are used as surrogate information to decide whether Fatty acids, C8-10, C8-10 alkyl esters (CAS 129677-93-6) fulfils the PBT or vPvB criteria.
Persistence Assessment
Based on the available data, Fatty acids, C8-10, C8-10 alkyl esters is considered to be readily biodegradable. Thus, the substance does not meet the screening criterion for persistence and it is not considered to be P or vP.
Bioaccumulation Assessment
The bioaccumulation potential of Fatty acids, C8-10, C8-10 alkyl esters is expected to be low. This assumption is based on a low bioavailability of the substances due to its ready biodegradability, high adsorption potential and low water solubility. Furthermore, the substance is rapidly metabolised and excreted by organisms and thus significant accumulation is not expected. This is supported by calculated low BCF/BAF values of14.07 - 207.8 L/kg whole body ww and 230.8 - 314 L/kg whole body ww, respectively (Arnot-Gobas estimate, including biotransformation, upper trophic). Please refer to IUCLID Section 5.3 for a detailed overview on bioaccumulation of the substance. Thus, taking all information into account, the test substance is not considered to be B or vB.
Toxicity Assessment
Long-term toxicity testing with aquatic invertebrates and aquatic algae resulted in no effects up to the limit of water solubility. All available short-term toxicity data did not result in any toxicity up to the water solubility limit as well. Moreover, Fatty acids, C8-10, C8-10 alkyl esters is not classified according to Regulation (EC) No 1272/2008 (5th 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.
Conclusion
Fatty acids, C8-10, C8-10 alkyl esters is no PBT/vPvB substance.
