Solid antiperspirants are made with several ingredients, including wax, a liquid emollient and an active-ingredient compound. It's the active ingredient that gives antiperspirants their sweat-blocking power. All antiperspirants have an aluminum-based compound as their main ingredient. If you look at the back of an antiperspirant container, the aluminum-based compound is always the first ingredient listed. Here are a few of the common active ingredients:
Aluminum zirconium tricholorohydrex glycine
The aluminum ions are taken into the cells that line the eccrine-gland ducts at the opening of the epidermis, the top layer of the skin, says dermatologist Dr. Eric Hanson of the University of North Carolina's Department of Dermatology. When the aluminum ions are drawn into the cells, water passes in with them. As more water flows in, the cells begin to swell, squeezing the ducts closed so that sweat can't get out.
