As the name suggests, deodorants are applied primary to mask the body odour. The body odour results from the bacterial action following perspiration. A deodorant must therefore, possess antibacterial properties. Aluminium salts have been found to possess excellent antibacterial properties. In addition to aluminium salts, $ZnO$and ${\left( {{C_{17}}{H_{35}}COO} \right)_2}Zn$also find use in deodorants preparation because they are astrinagents as well as antiseptics.
