Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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, 2014) are used as information to decide whetherFatty acids, C18-unsatd., dimers, hydrogenated, 2-ethylhexyl esters (CAS 68440-06-2)may potentially fulfil the PBT or vPvB criteria.
Persistence Assessment
Based on the available data, Fatty acids, C18-unsatd., dimers, hydrogenated, 2-ethylhexyl esters (CAS 68440-06-2) is not readily biodegradable. Thus, the substance may potentially fulfil the P/vP criteria.
Bioaccumulation Assessment
The bioaccumulation potential of Fatty acids, C18-unsatd., dimers, hydrogenated, 2-ethylhexyl esters (CAS 68440-06-2) is expected to be low. This assumption is based on the physico/chemical properties such as low water solubility and high potential for adsorption a reduced availability in water is expected. The high molecular weight of the substance significantly reduces the absorption due to steric hindrance to cross biological membranes. It can be concluded that the bioaccumulation potential of Fatty acids, C18-unsatd., dimers, hydrogenated, 2-ethylhexyl esters is negligible. BCF/BAF values estimated by QSAR (BCFBAF v3.01) also support this assumption (BCF values all well below 2000 L/kg). Please refer to IUCLID section 5.3 for a detailed overview on bioaccumulation of the substance. Thus, taking all information into account, the substance is not considered to be B or vB.
Toxicity Assessment
Aquatic toxicity data for the assessment of the substance were taken from a structurally similar source substance. All available data did not result in any toxicity up to the water solubility limit. Moreover, the target substance and the source substance used to predict environmental toxicity is not classified according to Regulation (EC) No 1272/2008 (CLP) considering Regulation (EU) No 605/2014 (5th ATP). Thus, the criteria given in the “Guidance on information requirements and chemical safety assessment, chapter R.11: PBT Assessment” (ECHA, 2014) are not met and the target substance as well as the source substance are 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.
