摘要:
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/cm3)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 ratio of an elastic to viscous moduli 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 &mgr;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.

Disclosed are aqueous and anhydrous deodorant compositions which comprise from about 0.1% to about 89.9% by weight of a cyclodextrin odor controlling agent, from about 0.1% to about 30% by weight of a solid non-polymeric gellant and from about 10% to about 90% by weight of an aqueous or anhydrous liquid carrier. Also disclosed are methods of using and making the compositions. The disclosed compositions are especially effective at preventing or eliminating malodors resulting from perspiration.
摘要:
The present invention is directed to antiperspirant compositions which comprise from about 0.1% to about 99.9% by weight of solubilized or solid antiperspirant active and from about 0.1% to about 99.9% by weight of a carrier which comprises 1,2-hexanediol, preferably in combination with a volatile silicone liquid carrier and dimethiconol as a coupling agent. The 1,2-hexanediol carrier is a highly effective coupling agent and is milder to the skin when applied topically to the axilla or other areas of the skin as compared to many other polyol-containing carriers. Preferred are antiperspirant compositions containing solubilized antiperspirant active.

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 gram.multidot.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, 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.

Disclosed are gel deodorant compositions comprising (a) from about 0.001% to about 50% by weight of a deodorant active, fragrance, or combination thereof; (b) from about 0.01% to about 20% by weight of a gellant; (c) from about 5% to about 90% by weight of a polymeric alcohol having at least one free hydroxyl group and also having from about 2 to about 80 alkoxylate radicals wherein the alkoxylate radical contains from about 2 to about 6 carbon atoms; (d) from about 5% to about 89% by weight of a nonpolymeric alcohol having at least two free hydroxyl groups, and also having from about 4 to about 20 carbon atoms, wherein the weight ratio of the polymeric to nonpolymeric alcohol is from about 18:1 to about 1:5; (e) from zero percent to about 10% by weight of glycerin; and (f) from about 0.01% to about 89% by weight of water. Also disclosed is a method of controlling malodor associated with perspiration by topical application of any deodorant composition containing a select combination of triclosan and triclocarban. All of these compositions remain clear or translucent over extended periods of time, and provide little or no skin irritation in addition to improved cosmetic benefits such as dry feel, ease of application, emolliency, fragrance longevity, and no powdery residue.
摘要:
Disclosed are cosmetic gel-solid stick compositions comprising particulate antiperspirant active, a fatty acid gellant having a select dimer-to-monomer ratio and an optional secondary gellant, and an anhydrous liquid carrier. The select dimer-to-monomer ratio of the fatty acid gellant helps provide the composition with improved hardness, low residue performance and efficacy, especially when used in combination with a secondary gellant.

Disclosed are antiperspirant and deodorant compositions and corresponding methods of application, wherein the compositions are single-phase systems that comprise a solubilized antiperspirant active, a silicone elastomer and a volatile silicone. These compositions provide improved low residue performance, enhanced stability, and improved cosmetics.
摘要:
Disclosed are antiperspirant and deodorant compositions having improved stability, low residue performance and/or improved cosmetics. These compositions comprise select concentrations of cyclohexasiloxane as a volatile silicone material from about 0.1% to about 50% by weight of an antiperspirant active, and from about 0.1% to about 50% by weight of a suspending agent, wherein the compositions are preferably substantially free of cyclotetrasiloxane. The selection of cyclohexasiloxane over other volatile silicone materials provides improved low residue performance, and especially when formulated as an aqueous emulsion it provides improved product stability in the form of extended duration of time within which the emulsion remains clear or nearly so.
