Abrasives are used in cosmetics to remove unwanted tissue or foreign materials from various body surfaces. The removed materials may include dead skin surface cells, callus, or dental plaque. As a rule, abrasives are irregularly shaped fine or coarse solids. Harder abrasives include special forms of Hydrated Silica used for tooth cleansing, while softer abrasives such as Oatmeal are employed to remove dead skin surface cells. Abrasive agents can also be used to produce gloss, e.g., on nails, by removal of surface imperfections. |
