Sweat is essentially odorless until bacteria ferment it. Deodorants are usually alcohol-based, and to fight odor, may use hops as antimicrobials.
However, despite their efficiency, aluminum salts are linked with damage to the blood-brain barrier, to various cancers, and renal (i.e., kidney) difficulties. Consequently, natural/organic preparations are always deodorants, never antiperspirants.
Deodorant forms are waxy push-up sticks, liquid roll-ons, body sprays (which can also be used on the feet and other body parts), and solid irregular rock shapes.
