Embodiment

[0158] The following non-limiting examples are used to illustrate the specific embodiments of the antiperspirant gel-solid stick composition of the present invention, including its preparation and application methods.

[0159] The listed components except for the antiperspirant active substance and other substances such as perfume are mixed to prepare the exemplified compositions. The mixed components are heated to 100°C with stirring to form a hot liquid, and then all other substances are added to the hot liquid. The heated liquid is stirred and cooled until the solidification point is about to be reached, at which time the cooled liquid composition is filled into the applicator package, allowed to cool and solidify to the necessary product hardness.

[0160]Each exemplified composition includes a crystal gel matrix containing crystal particles, the aspect ratio of the crystal particles is greater than about 6, and the average crystal gelling agent particle size is less than abou...

Abstract

Disclosed are anhydrous antiperspirant gel-solid stick compositions which comprise a particulate antiperspirant active; a solid non-polymeric gellant that is substantially free of dibenzylidene alditol, n-acyl amino acid derivatives, organic polymeric gellants, and inorganic thickening agents; and an anhydrous liquid carrier having an average solubility parameter of from about 3 to about 13 (cal / cm<3>)<0.5>, wherein the composition has a visible residue index of from about 11 to about 30 L-value, a product hardness of from about 500 gram.force to about 5,000 gram.force, a rheology profile defined by a ratio of an elastic modulus (G') to a viscous modulus (G'') of from about 0.1 to about 100. The refractive indices of the particulate antiperspirant active, solid non-polymeric gellant, and anhydrous liquid carrier are not matched. The solid non-polymeric gellant is preferably a crystalline material having an average particle size of less than about 1 mu m, and / or has an elongated particle morphology having an aspect ratio of greater than about 2. These antiperspirant gel-solid stick compositions provide improved low residue performance, antiperspirant and aesthetics.

Description

[0001] Field [0002] The present invention relates to an antiperspirant composition in the form of a gel-solid stick. The present invention particularly relates to compositions that provide improved low-residue performance, efficacy, and aesthetics in the form of gel-solid sticks of choice. Background technique [0003] Various topical antiperspirant products are commercially available or known in the field of antiperspirants. Most products are formulated as aerosols or sprays, roll-on liquids, pastes, emulsions, gels, gel-solids or other solid stick formulations, and include astringent substances (such as Zirconium salt or aluminum salt or a combination thereof) is added to a suitable carrier. These products should have effective anti-perspiration and anti-odor effects, and be aesthetically acceptable when applied to the armpit or other skin areas or after application. [0004] Among these products, solid anti-perspirant sticks are es...
