Do you know what modern people fear most about makeup? Powder card powder, eye shadow clumps, uneven color, oily face and so on, in order to avoid tragedy, cosmetics in the preparation of a variety of powder materials, they are various, different performance, silicon dioxide is a very common component in daily chemical products.
Nano silica is a kind of inorganic chemical materials, commonly known as silica, appearance is amorphous white powder, non-toxic, tasteless, no pollution, microstructure is spherical, a quasi particle structure of flocculent and mesh, formula and structural formula for SiO2, stable chemical properties, insoluble in water and acid (except hydrofluoric acid) and organic solvents, soluble in alkali and hydrofluoric acid.
Because it is ultrafine nano level, the size range is 1~100nm, so it has many unique properties, such as the optical performance of uv resistance, can improve the aging resistance of other materials, strength and chemical resistance.
According to relevant data statistics, in the cosmetics series launched in the last five years, such as foundation, cream, emulsion and so on, about 10% contain silica additives. Silica can increase viscosity, improve overall stability, uniform pigment distribution and prevent decolorization in lipstick. In makeup and eye care, silica is a highly effective anti-caking agent and free-flowing agent, which can improve storage stability and dispersion of powdery products.
