Abstract
Growing consumer preference for natural products has prompted interest in the use of plant extracts as plant raw materials providing active ingredients for cosmetics. This study focuses on vine tendrils, a by-product of grape cultivation, as a sustainable source of bioactive compounds. The idea of loan extraction using components borrowed from the final formulation was applied to extract valuable compounds from vine tendrils. The effectiveness of different extraction media was compared by analyzing the chemical profile of the extracts obtained using LC–MS/MS and UV–VIS techniques. The results obtained indicate the potential of extracts from grapevine tendrils as plant materials rich in bioactive substances with antioxidant properties, which supports their use in cosmetic products aimed at improving hair condition and skin protection. It is important to emphasize that grapevine tendrils are considered waste material that must be removed during vineyard maintenance. Cosmetics based on the processed extracts were prepared and evaluated. The viscosity, foaming properties, color parameters, and irritation potential of the developed cosmetics were assessed. The obtained results demonstrated the potential of the waste material as a valuable source of natural cosmetic components.
