Adsorption coefficient
Type:
log Koc
Value:
4.15
Temp.:
23.3 °C
Remarks on result:
other: Calculated from log Kow measured at this temperature

Applicant's summary and conclusion

Conclusions:
The calculated value of log Koc for FC-72 is 4.15 (log units) based on the experimental log Kow value of 5.0 at 23.3 °C
Executive summary:

The organic carbon adjusted adsorption coefficient (log Koc) of FC-72 was calculated from the measured log Kow value of 5.0 at 23.3 °C using the equation provided for predominantly hydrophobic chemicals in the European Chemicals Bureau: Technical Guidance Document on Risk Assessment, Chapter 4. The calculated value of log Koc is calculated to be 4.15 (log units). It is considered reliable (with restrictions) and is suitable for Risk Assessment, Classification & Labelling, and PBT Analysis.
