Abstract (EN): The cosmetic industry is a field on rise where the search for novel antioxidant ingredients, preferably from natural matrixes, became a new challenge. The reuse of Castanea sativa shells as a source of phytochemicals with pro-healthy effects in skin care products may be a valuable alternative to valorize this underexploited agro-industrial by-product. A previous study of our research group demonstrated the antioxidant properties of chestnut shells extract obtained by ultrasound-assisted extraction (UAE), as well as its safeness on skin cell lines, namely keratinocytes and fibroblasts. Based on the extract richness in antioxidants, a formulation containing C. sativa shells extract obtained by this environmentally friendly technology was successfully developed in the present study. The oil-in-water (O/W) cream incorporating the chestnut shells extract was further characterized regarding organoleptic and technological properties, namely color, pH, droplets size, and viscosity. A stability study over time was also accomplished. The results demonstrate that the formulation not only displayed pleasant organoleptic characteristics attractive to consumers but also a pH compatible with skin and a suitable viscosity for topical application. The stability study revealed minor changes to droplet size and color, without affecting the general stability of the formulation. In conclusion, this study emphasized the prominent benefits of chestnut shells extract as a novel ingredient for skin care formulations.
