Antimicrobial Compounds from Food Waste in Cosmetics

Abstract

The cosmetics industry has experienced rapid growth, driven by consumer demand for products in line with modern lifestyles and technological advances, with greater awareness of the impacts on health and the ecosystem. This review explores the potential use of antibacterial compounds derived from food waste as sustainable alternatives to synthetic preservatives in cosmetic products. Waste obtained from food, including fruit peels, seeds, and plant remnants, is rich in natural bioactives, including polyphenolic compounds and essential oils that exhibit antimicrobial, antioxidant, anti-inflammatory, and soothing features. The integration of these natural ingredients not only improves the shelf-life and safety of cosmetics but also promotes environmentally friendly practices. We discuss the sources and antimicrobial efficacy of these compounds, along with recent technological innovations. This sustainable approach responds to consumer preferences for natural ingredients, reduces food waste, and supports environmental sustainability, ultimately increasing the value and attractiveness of cosmetic products.
