Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 for fatty acids, tall-oil, esters with ethylene glycol (CAS 68187-85-9) 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
The hazard assessment is based on the data currently available. New studies with the registered substance and/or other member substances of the glycol esters category will be conducted in the future. The finalised studies will be included in the technical dossier as soon as they become available and the hazard assessment will be re-evaluated accordingly.
For further details, please refer to the category concept document attached to the category object (linked under IUCLID section 0.2) showing an overview of the strategy for all substances within the glycol esters category.
Fatty acids, tall-oil, esters with ethylene glycol (CAS 68187-85-9) is readily biodegradable (63% biodegradation after 28 d), as shown in a study conducted according to international guidelines. Thus, the substance does not meet the screening criterion for persistency and it is not considered to be P or vP.
Bioaccumulation
The bioaccumulation assessment was not conducted for the substance since it is not persistent and according to ECHA Guidance on Information Requirements and Chemical Safety Assessment Chapter R.11: PBT/vPvB assessment (2017) further generation of information on bioaccumulation is only necessary, if the P/vP criterion is fulfilled for the substance.
For a detailed reference list please refer to the CSR.
Toxicity
The hazard assessment is based on the data currently available. New studies with the registered substance and/or other member substances of the glycol esters category will be conducted in the future. The finalised studies will be included in the technical dossier as soon as they become available and the hazard assessment will be re-evaluated accordingly.
For further details, please refer to the category concept document attached to the category object (linked under IUCLID section 0.2) showing an overview of the strategy for all substances within the glycol esters category.
For the substance Fatty acids, tall-oil, esters with ethylene glycol (CAS 68187-85-9) the available acute effect concentrations are ≥ 0.1 mg/L (fish, aquatic invertebrates, algae). The substance is not classified as carcinogenic (category 1A or 1B), germ cell mutagenic (category 1A or 1B) or toxic for reproduction (category 1A, 1B or 2) according to Regulation (EC) No 1272/2008. In addition, the substance shows no specific target organ toxicity after repeated exposure (STOT RE category 1 or 2) according to Regulation (EC) No 1272/2008. The substance is readily biodegradable. Therefore, 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.
In conclusion fatty acids, tall-oil, esters with ethylene glycol (CAS 68187-85-9) is not considered to be 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.
