Aerosil 200 is a high-purity hydrophilic fumed silica with a very fine particle size and high specific surface area. It is widely used as a multifunctional performance additive in formulations where rheology modification, thickening, suspension, anti-settling, and flow control are required.

Aerosil 200 can increase the viscosity of liquid systems and help create a controlled thixotropic structure. This makes it useful for preventing pigments, fillers, and other solid particles from settling during storage while allowing the product to flow more easily when shear is applied.

In the cosmetic and personal-care industry, appropriately specified fumed silica can be used in selected formulations such as creams, gels, lotions, makeup products, and anhydrous systems to improve texture, consistency, suspension, and sensory properties.

In paints, coatings, adhesives, and sealants, it can improve rheology, anti-sagging performance, suspension stability, and processing characteristics.

Aerosil 200 is also used in pharmaceutical, printing ink, plastic, rubber, composite, and other industrial formulations as a functional silica additive.

The exact performance depends on the formulation, dispersion method, concentration, and compatibility with other ingredients.
