Results and discussion

Any other information on results incl. tables

The Koa value based on the experimental data is 2.46 at ca. 22 °C. The log Koa is 0.39.

Applicant's summary and conclusion

Conclusions:
The log Koa of HFP kinetic dimer is 0.39
Executive summary:

The octanol and air partition coefficient (Koa) of HFP kinetic dimer was calculated from the experimental dimensionless Henry’s Law constant of 5690 (22 °C) and the experimental Kow of 14,000 (22.1 °C) using the simple relationship: Koa = Kow/Kaw. The calculated log Koa is 0.39.

The Koa was calculated using GLP-compliant data according to an accepted formula. It is reliable with restrictions and suitable for use in Risk Assessment, Classification & Labelling, and PBT Analysis.
