Document Type and Number:
Japanese Patent JP2001507036
Kind Code:
A
Abstract:
Disclosed are anhydrous antiperspirant gel-solid sticks which comprise particulate antiperspirant active; a solid non-polymeric gellant that is substantially free of dibenzylidene alditol, inorganic thickening agents, organic polymeric gellants, n-acyl amino acid derivatives, or combinations thereof; an anhydrous liquid carrier containing polyalkylsiloxanes, polyalkyarylsiloxanes, polyestersiloxanes, polyethersiloxane copolymers, polyfluorosiloxanes, polyaminosiloxanes, or combinations thereof. The composition has a visible residue index of from about 11 to about 30 L-value, a product hardness of from about 500 to about 5,000 gramxforce, 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, the solid non-polymeric gellant, and the anhydrous liquid carrier are not matched. The compositions preferably comprise crystalline gellant particles having an average particle size of less than about 1 mu m and/or a particle morphology having an aspect ratio of greater than about 2. These compositions provide improved low residue performance, efficacy and aesthetics.
