The use of clays in cosmetics and dermocosmetics has a long history, dating back to prehistoric times. Clays are widely used due to their natural, low-cost, and environmentally friendly properties. They are applied as active compounds or cosmetic ingredients, contributing to various skin and hair care applications. The review highlights the types of clays and clay minerals used, their compositions, and their efficacy in cosmetic formulations. Despite the extensive literature on clay characterization, few studies have focused on their efficacy in cosmetic products, particularly in hair care. The review emphasizes the need for more scientific and technical information to guide the cosmetic industry in utilizing clays and clay minerals effectively. Clays are natural inorganic materials composed of finely divided particles that harden when mixed with water. They are rich in minerals such as aluminum, iron, magnesium, and titanium, which contribute to their functional properties. Clays can be classified based on their color, structure, and composition. Commonly used clays include smectites, fibrous clay minerals, kaolinites, and talc. These clays are characterized by their high surface area, adsorption capacity, cation exchange capability, and low toxicity. In cosmetic applications, clays are used for various purposes, including skin cleansing, oil control, substance adsorption, anti-aging, UV protection, and color enhancement. They can be formulated into ointments, gels, creams, and pastes, with considerations for rheology and sensory aspects. Clays are also used as starting materials in formulations to improve stability, rheology, and the release of active substances. The toxicological and safety aspects of clays are crucial. Clays must meet strict safety requirements, including chemical, physical, and toxicological standards. They should be free from heavy metals and microorganisms, and their purity and decontamination processes are essential. Studies have shown that clays can accumulate toxic elements and heavy metals, which must be carefully managed. When formulating cosmetics with clays, parameters such as particle size, shape, temperature, pH, and agitation are critical. Clays can form rigid networks or 3D structures in polar solvents, affecting their dispersion and stability. Swelling properties are important for achieving high-viscosity systems, and the concentration of clays in formulations can vary widely. Clays are used in a variety of cosmetic products, including exfoliants, masks, sunscreens, soaps, shampoos, toothpastes, deodorants, and makeup. They provide benefits such as adsorption of impurities, bactericidal and antiseptic properties, skin hydration, and UV protection. Clays are also used in hair care to treat conditions like dandruff, seborrheic dermatitis, and psoriasis. In conclusion, clays and clay minerals play a significant role in the cosmetic industry due to their multifunctional properties. Further research is needed to optimize their use in cosmetic formulations, ensuring bothThe use of clays in cosmetics and dermocosmetics has a long history, dating back to prehistoric times.
