Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: overall result

Reference
Name:
2,4,6-Trimethyl-2,4,6-tris(3,3,3-trifluoropropyl)cyclotrisiloxane
Type of composition:
boundary composition of the substance
State / form:
other: F-D3 may be a solid or liquid substance at room temperature depending on the proportion of the geometric isomers.
Reference substance:
2,4,6-Trimethyl-2,4,6-tris(3,3,3-trifluoropropyl)cyclotrisiloxane
PBT status:
the substance is not PBT / vPvB
Justification:

The substance does not meet the definitive criteria for persistence in the aquatic or sediment compartments; it is not P or vP. The hydrolysis/degradation products may meet the screening criteria for persistence (P/vP) in the sediment and soil compartments.

The substance does not meet the definitive criteria for bioaccumulation based on weight of evidence determination using expert judgement; it is not B or vB. F-D3 hydrolyses rapidly in water. The final hydrolysis product has a predicted log Kow of 1.0 and therefore does not meet the screening criteria for B/vB.

The substance meets the definitive criteria for toxicity; it is T.
