Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Henry's Law Constant: Calculated HLC for silanol hydrolysis product at environmental temperature (12°C): 1.4 E+10 Pa m3mol-1
Key value for chemical safety assessment
Additional information
The transfer of a substance from the water phase to the gas phase can be estimated by means of the Henry’s Law Constant (HLC). No measured value for this parameter is available. The HLC can be estimated from the ratio of the vapour pressure (VP) to the water solubility (WS).
HLC = (VP x MW)/WS
Where MW is molecular weight.
The calculated HLC value for F-D3 at environmental temperature (12°C) is very high, 1.4 E+10 Pa m3mol-1 (taken from EUSES 2.1.2).
The transfer of a substance from the soil phase to the gas phase can be estimated by the air-soil partition coefficient (Kair-soil). Kair-soil is calculated as Kair-water/Ksoil-water. Kair-water is the calculated dimensionless HLC; Ksoil-water may be determined using equations R.16-6/R.16-7 in REACH R16. The Kair-soil is calculated as 4.93 at 20°C (based on Kair-water 1.12E+07 and Ksoil-water 2.27E+06). A threshold Kair-soil >1 is used in order to determine the feasibility of testing in soil (OECD TG 222).
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.
