This group includes mined materials, various inorganic gases, liquids, or solids, some elemental substances, and inorganic oxides. Excluded are all substances which are classified as Inorganic Salts, Inorganic Acids or Inorganic Bases. As a rule, inorganics are chemically inert under conditions of cosmetic use. Some of them are used as pigments (e.g., Titanium Dioxide, Ultramarines, and Iron Oxides), while others are fillers, abrasives and smoothing agents (e.g., Kaolin, Talc, and Silica). The gaseous materials are used as propellants (e.g., Nitrogen). The clay-type materials (e.g., Magnesium Aluminum Silicate, Hectorite, and Montmorillonite) are used to increase the viscosity of aqueous suspensions. Hydrogen Peroxide is an important oxidizing agent which is used in cosmetics for hair bleaching and as a neutralizer in hair waving products, and to a lesser extent in oral care products. |
