Applications
Rheology control: Hydrophilic fumed silica is commonly used as a rheology modifier in various formulations such as paints, coatings, adhesives, and sealants. It helps to adjust viscosity, improve stability, and control flow characteristics, thereby enhancing the performance of these products.
Thixotropic agent: In many formulations, hydrophilic fumed silica serves as a thixotropic agent, meaning it can transform from a gel-like consistency to a more fluid state when subjected to mechanical agitation. This property is valuable in applications such as printing inks, where it helps prevent sagging and dripping during application.
Pharmaceutical applications: Hydrophilic fumed silica finds use in pharmaceutical formulations as a suspension aid, binder, and disintegrant in tablets and capsules. It improves powder flow properties, enhances drug dispersion, and facilitates controlled release of active ingredients.
Personal care products: In cosmetics and personal care products, hydrophilic fumed silica is utilized as a thickening agent, suspending agent, and abrasive in toothpaste formulations, creams, lotions, and hair care products. It helps to achieve the desired texture, stability, and performance characteristics.
Food and beverage industry: Hydrophilic fumed silica is approved for use as a food additive and is employed in powdered products such as spices, flavorings, and powdered drinks to prevent caking and improve flowability. It also acts as a thickening agent in certain food formulations.
