Zeolites are microporous silicate structures that are able to trap odors without being absorbed into the body. Zeolites can consist of many different types of elements, not necessarily aluminum alone. However, zeolites that do partially contain aluminum work by trapping odors within their porous structures, not by blocking sweat glands after being absorbed into the body, as many antiperspirants that contain aluminum do. In this way, Advanced Deodorant is able to target odor-causing bacteria and block it, without being absorbed into the skin which could cause potential health problems.
