Corrosion-resistance Creaming

Bayer and Wiedemarm (1981) reported on the mineralogy of zirconium and its uses as precious stones (zircon, phianite, and dje-valithe are all very hard), mineral raw materials, foundry sand, abrasives, and corrosion-resistant metals. Insoluble zirconium silicates have been used in cosmetic creams, powders, and antiperspirants. Zirconium tetrachloride is a white powder that is very moisture-sensitive (Dressier et al. 1983). 

Both tinplate and aluminium sheet may be used to produce shallow drawn containers, the choice depending on cost versus product resistance. Dry products and nonaqueous creams are usually satisfactory in tinplate, whereas aqueous creams are better packed in aluminium. Alternatively, lacquered tinplate can be used for aqueous creams but there is always a chance of corrosion at any raw edges. Tinplate is stronger than aluminium for a given thickness.
