Activated charcoal has emerged as a significant ingredient in modern cosmetic formulations due to its exceptional adsorption properties and ability to remove impurities from the skin. With increasing environmental pollution and skin-related issues, there is a growing demand for effective and safe cleansing products derived from natural sources. Coconut husk, an abundant agricultural waste, offers a sustainable and economical raw material for the preparation of activated charcoal. The objective of this study is to review the preparation of activated charcoal from coconut husk and to propose a formulation for a charcoal-based face wash along with suitable evaluation parameters. Literature findings indicate that activated charcoal possesses a high surface area and porosity, enabling efficient adsorption of toxins, excess oil, and dirt from the skin surface. Additionally, the use of coconut husk contributes to waste valorisation and promotes eco-friendly product development. The proposed formulation incorporates activated charcoal with suitable surfactants, humectants, and stabilizing agents to achieve effective cleansing and skin compatibility. Evaluation parameters such as pH, viscosity, foamability, and stability are also considered to ensure product quality. In conclusion, coconut husk-derived activated charcoal shows promising potential in the development of herbal cosmetic formulations, offering both functional efficacy and environmental sustainability.
