Results and discussion

Any other information on results incl. tables

The Koa value based on the experimental data is 2.86 at ca. 22 °C. The log Koa is 0.46.

Applicant's summary and conclusion

Conclusions:
The log Koa of PPVE is 0.46
Executive summary:

The octanol and air partition coefficient (Koa) of PPVE was calculated from the experimental dimensionless Henry’s Law constant of 3200 (22.6 °C) and the experimental Kow of 9150 (21.9 °C) using the simple relationship: Koa = Kow/Kaw. The calculated log Koa is 0.46.

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.
