- Related composition:
- Propanoic acid, 3,3'-thiobis-, di-C11-14-isoalkyl esters, C13-rich
- Reference substance:
- Propanoic acid, 3,3'-thiobis-, di-C11-14-isoalkyl esters, C13-rich
- Reference substance:
- Propanoic acid, 3,3'-thiobis-, di-C11-14-isoalkyl esters, C13-rich
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT Assessment for the substance is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT/ vPvB assessment (ECHA, 2014).
Persistence
The substance is readily biodegradable based on the results of the ready biodegradation tests on the analogue substances. Thus, the test substance does not meet the screening criterion for persistence and it is not considered to be P or vP.
Bioaccumulation
The substance is not expected to bioaccumulate based on the predicted BCF value of the analogue substances which is much lower than BCF threshold value for bioaccumulation (2000 l/kg). Thus, the substance is not considered to be B or vB.
Toxicity
Toxicological studies on analogue substances were considered for the evaluation of the toxicity of the substance. Studies on the acute oral toxicity and repeated dose toxicity showed that it is not expected to be toxic after an acute exposure or after a repeated exposure via the oral route. It is also not classified for carcinogenicity, mutagenicity, reproductive or developmental toxicity. In this case, the substance does not meet the criteria for toxicity.
A chronic exposure of aquatic organisms to the substance is considered as unlikely due to the low bioavailability of the substance as a consequence of its ready biodegradability. Thus, bioaccumulation and chronic toxicity of the substance are not expected.
The substance thus does not meet the criteria for a classification for PBT/vPBT.
