Fumed silica, as a nano-scale inorganic material, plays an indispensable role in the field of daily chemicals. It is non-toxic, odorless, and pollution-free. It has the characteristics of small particle size, large specific surface area, and strong chemical inertness, providing strong support for the performance improvement of various daily chemical products.
In skin care products, fumed silica exhibits excellent thickening and stabilizing effects. Adding hydrophilic fumed silica to ointments, gels, and creams can significantly increase product viscosity, build a stable three-dimensional network structure, enhance product stability and thixotropy, make the application experience smoother, and eliminate astringency. In W/O emulsion products, hydrophobic fumed silica can reduce greasy feeling, improve product freshness, and optimize skin feel.
Color cosmetics are also inseparable from fumed silica. In nail polish, it can prevent pigmentation, enhance color durability, and increase product viscosity to ensure uniform distribution of pigments and make application smoother. In lipstick, fumed silica disperses pigments evenly, improves overall stability, and prevents softening and discoloration. In powdered makeup such as foundation and eye shadow, it acts as an anti-caking agent and free-flowing agent to improve storage stability and dispersibility of powdered products.
Hair care products also benefit from fumed silica. In hair dyes, it prevents premature reaction and agglomeration of powdered color components; in conditioners, hydrophilic fumed silica is compounded with quaternary ammonium compounds to improve combability and fullness of hair; in hair spray, it helps to increase the fullness of hair.
In antiperspirants, fumed silica can increase adsorption, viscosity, suspension stability, and overall stability. In toothpaste, it acts as a fine abrasive to improve polishing, remove residual sugar, and control rheology to prevent component separation.
With its own characteristics, fumed silica improves the quality of daily chemical products in all aspects and brings consumers a better user experience. With the deepening of research, its application prospects in the field of daily chemicals will be broader.
