Any Spray having the power of preventing, destroying, or masking undesired odors of the body is a Deodorant Spray. Deodorants are applied to the body, particularly the armpits, mainly to reduce body odor caused by the bacterial breakdown of perspiration. These are "antiperspirants", which prevent odor and reduce sweat produced by parts of the body. Antiperspirants are typically applied to the underarms, while deodorants can also be used on feet and other areas in the form of body sprays.
