A Multifunctional Enhancer in Cosmetics
As cosmetics technology advances, mesoporous silica loaded with active ingredients and microspherical silica with light-scattering capabilities are increasingly being used
Silica, with its controllable particle size distribution, excellent adsorption properties, and skin feel-modifying capabilities, has become a core functional ingredient in cosmetic formulations. Widely used in color cosmetics, skincare, and haircare, it plays a key role in oil control, makeup setting, texture optimization, and efficacy enhancement, meeting the quality requirements of high-end cosmetics.
Its core value stems from precise material design. Cosmetic-grade silica is produced via vapor phase or precipitation methods. Its particle size can be controlled to 5-1000 nm, with a specific surface area of 200-800 m²/g. Its surface can also be hydrophobically modified (e.g., trimethyl silylation) to achieve both skin-friendliness and functionality. This structure enables it to absorb both oil and water while enhancing product feel. Its safety is certified by the International Cosmetic Ingredient Standard (INCI).
In color cosmetics, it serves as an invisible aid in makeup setting and color development. Adding 15%-30% fumed silica to loose powders and face powders absorbs excess facial oil through its porous structure, extending makeup's hold to 6-8 hours while imparting a matte finish. In eyeshadow and blush, ultrafine silica acts as a pigment dispersant, improving color evenness and adhesion while reducing flyaways.
In skincare, silica primarily controls oil and enhances skin feel. Adding 5%-10% hydrophobic silica to oil-control serums and lotions creates a breathable film that absorbs oil without clogging pores. Micron-sized spherical silica in scrubs gently exfoliates dead skin cells, avoiding the risk of scratching caused by traditional abrasive particles.
In hair products, it improves hair texture and enhances the durability of styles. Adding silica to hairsprays and mousses enhances hold and prevents style breakage in humid environments. In conditioners, it enhances smoothness and reduces friction and damage to hair.
As cosmetics technology advances, mesoporous silica loaded with active ingredients and microspherical silica with light-scattering capabilities are increasingly being used, providing new avenues for enhancing cosmetics' efficacy and user experience.
