Definitions

• the present invention relates to a method and composition for controlling body odor and perspiration from localized areas of the body such as the underarm without leaving visible white residue on the skin and/or clothing.
• Sweating though a natural bodily function, results in the formation of wet patches on human skin or clothing. Moreover, the sweat secreted from sweat glands has a tendency to form a malodorous odor due to its interaction with the many microorganisms which reside on the underarm skin surface. These two phenomena are deemed to be undesirable in many societies.
• Antiperspirant products possess active ingredients which inhibit/suppress sweating, whereas deodorant products possess ingredients that mask the malodors caused by sweat. Many products address both phenomena simultaneously.
• aerosol sprays solids and roll-ons.
• the liquid compositions used in aerosol and roll-on products possess several drawbacks. First, they have a tendency to impart an unpleasant oily or sticky sensation onto skin when applied thereon. Secondly, they oftentimes take too long to dry after application. These compositions have a tendency, when applied to the armpits, to leave a visible white residue on the skin and/or clothing. When used regularly, these compositions oftentimes result in visible yellow colored stains on clothing after laundering. Both the white residue and yellow staining phenomena are caused, in part, by the aluminum salt actives contained in the composition.
