Abstract: The finding of new vesicular systems is a challenging process that depends on different factors such as the components used, the interactions between them or the dispersant media. Our objective was to develop a new vesicular delivery system formed by self-assembly of β-Sitosterol (Sit), Lauryl Glucoside (LGL) and Lauryl Glucose Carboxylate (LGC) molecules, all plant-based, biodegradable and biocompatible components. Nanovesicles (NVs) with different molar ratios of Sit, LGL and LGC were prepared using a single step method named DELOS, and characterized by dynamic light scattering, cryo-electron microscopy and small-angle X-ray scattering. Antioxidant compound α-tocopherol (TCP) was integrated in the NVs showing their potential to nanoformulate hydrophobic payloads. Finally, in vitro biocompatibility assays with reconstructed human epidermis and ex vivo skin retention studies using multiphoton microscopy and NVs labelled with Nile Red (NR) were carried out. As a result of this work, a new platform of NVs has been obtained by combining Sit, LGL and LGC, obtaining vesicular systems with tunable physicochemical properties in terms of size, surface charge and lamellarity, when the carbon chain of the alkyl polyglucoside was >12. The vesicles could efficiently integrate TCP, maintaining its antioxidant activity after loading, and showed biocompatibility with the skin improving the permeability of the poorly water-soluble molecule NR.
