Micron spherical silica gel for high performance liquid chromatography is a white powder with the main component SiO2.nH2O. It has stable chemical properties and does not react with other substances except HF and concentrated caustic solution; Due to its rich mesoporous structure, large pore volume, and high specific surface area, it has high tray efficiency in the adsorption, desorption, and separation of different substances. Micron spherical silica with high permeability for cosmetics is a white powder with a main component of SiO2. nH2O. Its chemical properties are stable, and it does not react with other substances except HF and concentrated caustic solution; Due to its rich mesoporous structure, large pore volume and high specific surface area, it can be used for moisturizing, breathable, loading/releasing effective nutrients in daily chemicals; Rich porous structure with a refractive index of 1.46 can effectively prevent ultraviolet rays, with a higher dispersion of micron sized spherical particles, optimizing the tactile feel of cosmetics and improving the product experience
