Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 PBT assessment of Tetraesters of 2,2-bis(hydroxymethyl)propane-1,3-diol and decanoic and octanoic acid (CAS 68441-68-9) is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2017).
Persistence
Tetraesters of 2,2-bis(hydroxymethyl)propane-1,3-diol and decanoic and octanoic acid (CAS 68441-68-9) is readily biodegradable. Thus, the substance does not meet the screening criterion for persistence and it is not considered to be P or vP.
Bioaccumulation
The substance is readily biodegradable and thus not persistent (P or vP). Therefore, no B-assessment was carried out since it is only required if the substance fulfills the P or vP criteria, according to the guideline (Guidance on Information Requirements and Chemical Safety Assessment Chapter R.11: PBT/vPvB assessment, 2017).
Toxicity
The available chronic effect concentrations (aquatic invertebrates and algae) are ≥ 0.01 mg/L and the available acute effect concentrations are ≥ 0.1 mg/L (fish, aquatic invertebrates and algae). Therefore, the criteria set out in Annex XIII of Regulation (EC) No 1907/2006 are not fulfilled and the target substance does not meet the T criterion.
In conclusion, the substance is not PBT/vPvB.
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.
