Deodorant that is not an antiperspirant does not keep a person from sweating, but does mask, reduce or eliminate the odor associated with perspiration. Non-antiperspirant deodorant works by neutralizing the odor-producing bacteria found in sweat. Non-antiperspirant deodorant typically does not contain aluminum, which is the active ingredient in antiperspirant.
Antiperspirant is controversial because it contains aluminum and other synthetic chemicals, and because it impacts the body's removal of toxins by inhibiting sweat glands. Non-antiperspirant deodorants are available with synthetic or natural ingredients. Because non-antiperspirant deodorants do not block perspiration, sweaty areas may still produce wet spots on clothing, though they should not have a foul odor.
