Aerosil R 202 is a fumed silica, specifically a form of silicon dioxide (SiO2), characterized by its high surface area and low density. It is produced through the vaporization of silicon compounds, followed by oxidation in a flame, resulting in a fine, white powder. This substance exhibits excellent thixotropic properties, meaning it can thicken or gel when subjected to shear stress, making it useful as a thickening agent in various applications. Aerosil R 202 is hydrophobic due to surface modifications, which enhances its compatibility with non-polar solvents and improves its performance in formulations. It is commonly utilized in industries such as pharmaceuticals, cosmetics, and coatings, where it serves as a flow agent, anti-caking agent, or stabilizer. Additionally, its high purity and low moisture content contribute to its effectiveness in enhancing the stability and performance of products. Safety data sheets indicate that while it is generally considered safe, appropriate handling measures should be taken to avoid inhalation of dust.
