Gaseous silica, also known as fumed silica, is a white, fluffy powder with porous properties, odorless, pollution-free, and high-temperature resistance. At the same time, its chemical inertia and special thixotropic properties significantly improve the tensile strength, tear resistance and wear resistance of rubber products. The strength of rubber products after improvement is increased by dozens of times. The rheology and thixotropy control of liquid systems, adhesives, polymers, etc. can be used to adjust free flow and as anticaking agent to improve powder properties, etc.


The application of fumed silica in the field of cosmetics is very extensive. Let's take a look at its uses!


In nail polish, fumed silica can ensure the uniform distribution of pigment in the brightener, prevent pigment precipitation, and provide good rheology of the final product, thus improving the coating property. If the refractive index of the solvent system used is consistent with that of fumed silica (1.48), transparent nail polish formulations can be formed, such as base color and surface color. Otherwise, when used at high concentrations, it has a matting effect and instead reduces the required gloss.


In lipstick, fumed silica can distribute pigments evenly, and greatly improve the temperature resistance, prevent lipstick from softening when the temperature rises. After being applied to the lips, it can prevent lipstick from transferring to the small lip lines and causing the bleeding, so that lipstick will not fade for a long time. When the concentration is high, the gloss will decrease.


Many eye and face makeup products, including honey powder, foundation make-up, rouge, eye black, eyeliner, etc., can only use fumed silica to obtain the required characteristics and necessary stability. Gaseous silica is an efficient anti caking agent and free flowing agent that can improve storage stability and dispersion of powdered products.
