Antiperspirants and deodorants are among the most widely used cosmetic products.

Antiperspirants are specifically designed to prevent perspiration (the process of removing sweat from the sweat glands). Often, antiperspirants have aluminum compounds. The most active are chloride and aluminum chloride. Aluminum salts coagulate skin proteins, cause depression of the secretory of the sweat glands and thus reduce the local sweat allocation. Antiperspirants are applied only to certain areas of the body, so they do not affect the process of sweating the body as a whole.

Deodorants do not stop sweating, but kill bacteria and mask the smell. Eliminating the unpleasant smell of the body occurs due to slowing down the decomposition and oxidation of sweat. As deodorant components, various compounds with antimicrobial action are used.
