Antiperspirants are astringent substances applied to the skin to reduce or prevent sweat. The process of sweating is an important, normal physiological process that enables us excretes excess water and salt from the body. However conditions like hyperhidrosis (excessive sweat) led to the need for control of sweat using antiperspirants, although antiperspirants are now used for cosmetic purposes in recent times. This study was conducted to determine the concentration of Aluminium (Al), which is the active ingredient in most antiperspirants and also to determine the presence and concentration of other metals such as Lead (Pb), Cadmium (Cd), Nickel (Ni), Zinc (Zn), and Copper (Cu). Ten (10) brands of antiperspirant samples marketed in Nigeria were purchased. All samples were pre-treated using acid digestion and the concentrations of Al, Pb, Cd, Ni, Zn and Cu were determined using Atomic Absorption Spectrophotometer (AAS)(Perkin Elmer A Analyst 200.Germany). For all the antiperspirant samples analysed, metals such a Cd, Ni, Zn and Cu were not detected while the concentrations of Al and Pb found were between (0.624 – 2.416mg/L) and (1.787 – 5.610mg/L) respectively. In comparison to the standard permissible limits of aluminium in antiperspirants, the percentage of aluminium in all the samples analysed was within the standard permissible limit set by the United States Food and Drug Administration (FDA). Nine samples conformed to over the counter antiperspirants value while one conformed to a prescription antiperspirant value. However, the presence of lead metal in the antiperspirant samples may be a health risk to the consumers.
