This study aimed to the evaluation of a new solid non-aqueous self-double-emulsifying drug-delivery system (SDEDDS) for topical application of quercetin. The new formulation was prepared through two-step emulsification process and could spontaneously form oil-in-oil-in-water (O/O/W) double emulsions after dilution with aqueous medium, with inner oil phase mainly containing the drug. Solid state characterisation was performed by DSC and X-ray powder diffraction. Furthermore, the optimised QT-SDEDDS displayed sustained release profile and was found to be stable up to 30 days under 4 degrees C and 25 degrees C. Antioxidant capacities showed that quercetin could be protected by the solid non-aqueous SDEDDS. Compared with the quercetin ethanol aqueous solution, the QT-SDEDDS exhibited higher permeation ability, and significantly increased accumulation of quercetin in the skin. These studies demonstrated that the solid non-aqueous SDEDDS might be a promising carrier for topical application of poorly water-soluble and simultaneously poorly oil-soluble drugs, such as quercetin.
