ZEOFREE® 200 is a high-purity, precipitated synthetic silicon dioxide primarily used in pharmaceuticals to optimize the processing and stability of powder formulations. It functions as a liquid carrier by utilizing its highly porous, "sponge-like" structure to absorb liquid active ingredients and convert them into free-flowing powders. It also acts as a free-flow aid/glidant: It coats the surface of larger particles, reducing inter-particle friction. This is critical for ensuring that powders flow smoothly and consistently through tableting equipment and high-speed capsule fillers, which prevents weight variation in the final dosage forms. Zeofree® 200 is primarily used in solid oral dosage forms where high precision and material stability are required.
