Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Name:
- Di-n-octyltin bis(2-ethylhexyl maleate)
- Type of composition:
- boundary composition of the substance
- State / form:
- liquid
- Reference substance:
- Di-n-octyltin bis(2-ethylhexyl maleate)
- Name:
- Di-n-octyltin bis(2-ethylhexyl maleate)
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Reference substance:
- Di-n-octyltin bis(2-ethylhexyl maleate)
- 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, 2017).
Persistence
The substance is considered as non readily biodegradable based on the results of the ready biodegradation tests. Thus, the test substance meets the screening criterion for persistence. No degradation half times are available therefore it is not clear whether the substance is just Persistent or very Persistent.
Bioaccumulation
The substance is not expected to bioaccumulate based on the predicted BCF value of the substance 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
Studies on the repeated dose toxicity and reproduction/development toxicity showed that the substance is expected to be toxic after a repeated exposure via the oral route. The substance is not classified for carcinogenicity or mutagenicity. In this case, the substance does not meet the criteria for toxicity.
L(E)C50 values were higher than the water solubility after the short-term exposure of aquatic organisms to the substance. The neglible water solubility of the substance does not necessarily mean that the substance is not available for the aquatic organisms, rather in combination with the non-biodegradability and the non-hydrolysis of the substance suggests a persistence in the aquatic environment and a potential toxicity.
The substance does not meet the criteria for a classification for PBT/vPBT since it does not fulfil the criteria for all three inherent properties.
