Problems solved by technology

It has been found that most other surfactants, when added to anhydrous antiperspirant creams as defined herein, prevent or inhibit the precipitation of the antiperspirant active in the sweat ducts, thus reducing the antiperspirant efficacy

Abstract

The invention discloses anhydrous antiperspirant cream compositions that have improved wash-off performance and good antiperspirant efficacy, which compositions have a penetration force value of from about 75 gram.force to about 500 gram.force, a delta stress value of from about 300 dyne / cm2 to about 8,000 dyne / cm2 as measured after extrusion of the composition through a shear force delivery means, and a static yield stress value of at least about 1,000 dyne / cm2 as measured after extrusion of the composition through a shear force delivery means. These compositions comprise from about 0.1% to about 20% by weight of a crystalline gellant, from about 10% to about 80% by weight of an anhydrous liquid carrier for the crystalline gellant wherein the anhydrous liquid carrier has a solubility parameter of from about 3 to about 13, from about 5% to about 35% by weight of a particulate antiperspirant active, and from about 0.001% to about 5% by weight of an anhydrous liquid surfactant which is selected from the group consisting of nonionic surfactant, amphoteric surfactant, and combinations thereof. Also disclosed are methods of using and making the compositions.

Description

technical field [0001] The present invention relates to anhydrous antiperspirant cream compositions having improved rinse-off performance and antiperspirant efficacy. The invention also relates to a process for the preparation of the composition. Background of the invention [0002] A variety of topical antiperspirant products are commercially available or otherwise known in the antiperspirant art. Most products are formulated as sprays, roll-ons, creams or solid sticks and include astringent ingredients such as zirconium or aluminum salts in an appropriate topical carrier. These products are designed to provide effective perspiration and odor control and are cosmetically suitable for application to or after application to the armpits or other areas of the skin. [0003] Among these products, antiperspirant creams are gaining popularity as an effective alternative to antiperspirant sprays and solid sticks. The creams may be applied by conventional methods, or these creams...
