Design of Decanoic Acid/Polysorbate 80 Composite Vesicles as Cosmetics Carrier: Stability, Skin Permeability, Antioxidant and Antibacterial Activity.

ABSTRACT: Fatty acid vesicles are natural biomaterials which possess unique bilayer structures and offer biomimetic advantages for drug and gene delivery. Nevertheless, the formation of fatty acid vesicles is limited to neutral alkaline circumstances and cannot adapt to the acidic environment of the living system. In this work, the non-ionic surfactant polysorbate 80 (TW80) was introduced, extending the pH window of vesicles formed by decanoic acid (DA) from 6.90-7.80 to 2.28-6.31. The DA/TW80 composite vesicles were used to encapsulate quercetin (QT), achieving an encapsulation efficiency of up to 75.6%. The formation of DA/TW80/QT composite vesicles was confirmed through Fourier transform infrared spectroscopy, differential scanning calorimetry, and X-ray diffraction. Moreover, free QT was release
