The chief ore of aluminum is bauxite. Aluminum-containing raw materials are used safely and extensively in cosmetics, pharmaceuticals and over-the-counter (OTC) drug products. In cosmetics, they function as pigments and thickening agents. Aluminum compounds also function as active ingredients in OTC drugs such as antacids and antiperspirants.
It is primarily composed of the insoluble fraction of the bauxite ore that remains after extraction of the aluminium-containing components. Iron oxides (10 – 30%), titanium dioxide (2 – 15%), silicon oxide (5 – 20%) and undissolved alumina (0 – 20%) make up the residue, together with a wide range of other oxides which will vary according to the initial bauxite source.
