- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Reference substance:
- Triacetoxyvinylsilane
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence Assessment
Evidence of ready biodegradation:
Study report: The substance is biodegradable (read-across fromstudy performed according to OECD Guideline 301F).
The substance is not fulfilling the criteria for Persistence (P)
Bioaccumulation Assessment
The log Kow value of the substance is lower than 4,5(calculated log Pow of the substance is 0.60 (EPI-Suite, EPA USA / KOWWIN v1.67).
The substance is not fulfilling the criteria for Bioaccumulation (B)
Toxicity Assessment
There is no long-term toxicity studies available with fish and daphnia.
- Short-term toxicity to fish. Weight of evidence: LC50 (96h) = 101.86 mg/L (based on mortality) (read-across from supporting substance acetic acid).
- Short-term toxicity to aquatic invertebrates: Weight of evidence: EC50 (48h) = 83.81 mg/L (based on mobility, without pH adjustment) (read-across from supporting substance acetic acid).
- Toxicity to aquatic algae: Key study: EC50 (72h) = 22.83 mg/L and NOEC (72h) = 16.84 mg/L (based on growth rate, without pH adjustment) (read-across from analogue substance propyltriacetoxysilane)
No classified as CMR.
Not classified for Specific target organ toxicity after repeated exposure.
The substance is not fulfilling the criteria for Toxicity (T)
Summary and overall Conclusions on PBT or vPvB Properties
Triacetoxyvinylsilane is not a PBT or vPvB substance.
