Water-Soluble Formulations of Curcumin and Eugenol Produced by Spray Drying.

ABSTRACT: Background/Objectives: In this study, we present a green, scalable platform for the production of water-dispersible powders co-encapsulating the lipophilic bioactives curcumin (Cur) and eugenol (Eug) within the amphiphilic polymer Soluplus^® (SP) via low-temperature spray drying. Methods: The amount of Cur (1%, 5%, and 10%) and Eug (5%, 10%, 15%, and 20%) was varied to achieve single- and double-loaded water-soluble powders with the maximum amount of active substances. The powders containing a higher loading of Cur, 5% and 10% (and Eug), were obtained from water/ethanol mixtures (2:1 and 5:1 v/v ratio), while the formulation with 1% of Cur was spray-dried by using water as a solvent. Results: By leveraging aqueous or aqueous-ethanolic feed syste
