Aubergine peel is an excellent source of phytonutrients, dietary fibers and minerals. In addition, this biomass is high in anthocyanins, phenolic acids and flavonoids, β-carotene and other compounds with antioxidant, antiradical and antimicrobial properties. In this research dry aubergine peel was extracted with subcritical water in nitrogen atmosphere (40 bars), applying 130°C for 30 minutes and agitation (500 rpm). After extraction the extract was lyophilized and further used in the development of two types of cosmetic products: day face cream with SPF 20 (Picture 1), and aftershave gel for men (Picture 2). In both cosmetic products dry aubergine peel extract was incorporated in 0.3% fraction. Other active ingredients used for manufacturing of face cream included allantoin, panthenol, propylene-glycol, tocopheryl acetate, elastin and micro collagen, with propylene-glycol and glycerin as humectants, and isopropyl-myristate as emollient. Developed aftershave gel was formulated to have antiseptic, soothing and cooling properties. Besides aubergine peel extract, other active ingredients used in the formulation of aftershave gel, included camphor, menthol, allantoin and salicylic acid.
