Fumed Silica ( Aerosil Silica )
Fumed silica serves as a universal thickening agent and an anti-caking agent (free-flow agent) in powders. Like silica gel, it serves as a desiccant. It is used in cosmetics for its light-diffusing properties. It is used as a light abrasive, in products like toothpaste.
