Solubilization thermodynamics of ibuprofen in modified and classical FeSSIF biorelevant media

► Apparent solubility of ibuprofen was determined in FeSSIF media at several surfactant concentrations and temperatures. ► Micellar partition coefficient of ibuprofen in FeSSIF media was calculated at several temperatures. ► Thermodynamic quantities of transfer of ibuprofen from water to micelles in FeSSIF media are reported.
