Silica hydrate is widely used in the pharmaceutical industry as an excipient in tablet formulations. It acts as a glidant, improving the flow properties of powdered materials during the manufacturing process. This ensures uniform distribution and consistent tablet weight. Additionally, it serves as a desiccant in packaging to protect moisture-sensitive drugs, maintaining their stability and efficacy. In the cosmetics industry, it is utilized as an absorbent in skincare products, such as powders and foundations, to control excess oil and provide a matte finish. Its mild abrasive properties make it suitable for use in toothpaste, where it aids in cleaning and polishing teeth without damaging enamel. In the food industry, silica hydrate is employed as an anti-caking agent in powdered products like spices, seasonings, and instant soups. It prevents clumping, ensuring free-flowing consistency and ease of use. Industrially, it is used as a filler and reinforcing agent in rubber, plastics, and coatings, enhancing durability and mechanical properties. Its high surface area and porosity also make it valuable in chromatography as a stationary phase for separating and analyzing chemical compounds.
