EVALUATION OF ALUMINUM CONTENT IN ANTIPERSPIRANTS

Abstract

The antiperspirant works by diffusing the aluminum salt through the ducts of the sweat glands into the opening of the epidermis. After contact with perspiration sweat, a mucopolysaccharide complex is produced that reduces perspiration. When its content is high in blood, the bones capture and release it slowly causing bone dystrophy. The objective of this project was to determine the levels of aluminum in the antiperspirant, of different brands marketed in supermarkets, and to verify if the concentrations are in agreement with the label and in accordance with the legislation. The complexometric titration method was used. Of the three brands analyzed, the first one did not present aluminum, important for the antiperspirant effect, the second one contained lower amounts than the one informed on the label and the third one presented levels above that allowed by the legislation. Therefore, none of the analyzed brands presented positive results.
