PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- Reaction mass of decamethyltetrasiloxane; dodecamethylpentasiloxane; hexamethyldisiloxane; octamethyltrisiloxane
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Reference substance:
- Reaction mass of decamethyltetrasiloxane; dodecamethylpentasiloxane; hexamethyldisiloxane; octamethyltrisiloxane
- Reference substance:
- Reaction mass of decamethyltetrasiloxane; dodecamethylpentasiloxane; hexamethyldisiloxane; octamethyltrisiloxane
- Reference substance:
- Reaction mass of decamethyltetrasiloxane; dodecamethylpentasiloxane; hexamethyldisiloxane; octamethyltrisiloxane
- Reference substance:
- Reaction mass of decamethyltetrasiloxane; dodecamethylpentasiloxane; hexamethyldisiloxane; octamethyltrisiloxane
- Name:
- Reaction Mass of decamethyltetrasiloxane; dodecamethylpentasiloxane; hexamethyldisiloxane; octamethyltrisiloxane
- Type of composition:
- boundary composition of the substance
- State / form:
- liquid
- Reference substance:
- Reaction Mass of decamethyltetrasiloxane; dodecamethylpentasiloxane; hexamethyldisiloxane; octamethyltrisiloxane
- Reference substance:
- Reaction Mass of decamethyltetrasiloxane; dodecamethylpentasiloxane; hexamethyldisiloxane; octamethyltrisiloxane
- Reference substance:
- Reaction Mass of decamethyltetrasiloxane; dodecamethylpentasiloxane; hexamethyldisiloxane; octamethyltrisiloxane
- Reference substance:
- Reaction Mass of decamethyltetrasiloxane; dodecamethylpentasiloxane; hexamethyldisiloxane; octamethyltrisiloxane
- PBT status:
- the substance is not PBT / vPvB
- Justification:
L3 does not meet the definitive criteria for persistence in the aquatic or soil compartments; it is not P or vP. The screening criteria for persistence (P/vP) in the sediment compartment are met.
L3 does not meet the definitive criteria for bioaccumulation based on weight of evidence determination using expert judgement; it is not B or vB
L3 does not meet the definitive criteria for toxicity; it is not T.
