• Alum — A double hydrated sulfate of aluminum and an alkali metal (usually potassium), with the general chemical formula KAl(SO4)2·12H2O, crystallizing in the cubic system; a structural substance with potent astringent, hemostatic, and antiseptic properties, traditionally known as alum. In industry, it is widely used as a mordant in dyeing, a tanning agent in leather processing, a clarifying agent for water purification, and in cosmetics as a natural antiperspirant due to its capacity to contract tissues and inhibit bacterial proliferation.
• Antiperspirant — Reducing, blocking, or controlling the elimination of sweat through skin pores; a cosmetic product or pharmaceutical preparation structurally formulated with metallic salts (usually aluminum) that temporarily plug sweat gland ducts. This dual element prevents moisture and unpleasant odors, unlike a classic deodorant which only masks the scent.
• Antisudoral — Reducing, limiting, or stopping the excessive secretion of sweat from the sweat glands in the skin. It is typically used to describe cosmetic products, dermatological treatments, or active chemical substances that act locally by temporarily blocking pores or regulating glandular activity, providing protection against moisture and unpleasant odors.
• Antitranspirant — A cosmetic product or dermatological preparation designed to reduce or temporarily block the secretion of sweat from the sweat glands in the skin. It typically acts via metallic salts (such as aluminum chlorohydrate) that form a superficial gel plug inside the pores, preventing moisture and unpleasant odors, unlike a simple deodorant which merely masks the smell.
