Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- [2-(Perfluorohexyl)ethyl]triethoxysilane
- Type of composition:
- boundary composition of the substance
- State / form:
- liquid
- Reference substance:
- [2-(Perfluorohexyl)ethyl]triethoxysilane
- PBT status:
- further information relevant for the PBT assessment is necessary
- Justification:
The parent substance, [2-(perfluorohexyl)ethyl]triethoxysilane hydrolyses moderately rapid in contact with water. However, hydrolysis rates alone cannot be used to conclude that a substance is not persistent in all environmental compartments including soil and sediments since hydrolysis may be slower in these compartments. Therefore, in order to assess the persistence potential of the registration substance in the environment, further generation of data for the soil compartment is considered necessary. The conclusion on persistence or non-persistence would be revisited once experimental evidence is available.
- Likely routes of exposure:
No conclusion can be reached for the registration substance based on available information.
The hydrolysis products do not meet the criteria for PBT therefore emission characterisation is not required.
Reference
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
