This high surface area amorphous silicon dioxide (SiO₂), with a specific surface area of 237.2 m²/g, pore volume of 0.842 cm³/g, and average pore diameter of 14.21 nm, is a specialty chemical widely used as a functional additive. In the food industry, it acts as an anti-caking agent (E551) in powdered products to improve flowability. In cosmetics, it serves as a thickening agent, absorbent, and mattifying agent in creams, powders, and foundations. In pharmaceuticals, it functions as a glidant, filler, and excipient in tablets and capsules for better flow and stability, and its porosity supports drug delivery. Its mild abrasive properties make it ideal for toothpaste. Additional applications include reinforcing filler in rubber and tires, matting agent and thickener in paints/coatings, catalyst support in chemical processes, adsorbent in chromatography and purification, and components in electronics composites and polishing slurries.
