Abstract:
Disclosed is a solid (e.g., cream, such as semi-solid or soft solid) cosmetic composition containing an active cosmetic material (e.g., a deodorant active, an antiperspirant active, a sunscreen, an insect repellent and/or an anti-fungal agent), volatile (e.g., cyclomethicone) and linear chain (e.g., dimethicone and/or phenyl trimethicone) silicone materials, and at least one gelling agent. The at least one gelling agent includes hexanediol-behenyl beeswax, and is included in the composition in an amount sufficient to provide the solid composition. By incorporating the hexanediol-behenyl beeswax as a gelling agent, conventional gelling agents such as fatty alcohols and hydrogenated castor oil need not be incorporated in the composition. When an antiperspirant active material is incorporated in the solid composition containing hexanediol-behenyl beeswax as a gelling agent, a solid antiperspirant composition that is efficacious and leaves no visible (white) residue, can be achieved.
Abstract:
A two-phase roll-on antiperspirant and/or deodorant is described which comprises: (a) a clear, translucent or opaque non-polar phase having a viscosity in the range of 20 cps -- 9,000 made by combining: a cross-linked or partially cross-linked non-emulsifyingsiloxane elastomer; 0.1-70 weight % of one or more low viscosity, lipophilic emollients; (b)a clear, translucent or opaque polar phase having a viscosity in the range of 20 -- 9,000 cpsmade by combining: one or more members selected from the group consisting of water,glycols and polyhydric alcohols; and an antiperspirant active salt which is soluble or suspendible in the polar phase;wherein the polar phase comprises (i) a sufficient amount of water, glycols or polyhydric alcohols to dissolve or suspend the antiperspirant active, and (ii) optionally may comprise up to 30 weight % water; up to 16.00 weight % of ethyl alcohol; up to 16 weight % isopropyl alcohol; or mixtures of the foregoing; (iii) 0.1-2.5 weight % of a water soluble cationic derivative selected from the group consisting of hydroxyethyl cellulose and its copolymers provided that the viscosity of the polar phase does not exceed 9,000 cps.
Abstract:
Disclosed is a solid cosmetic composition (e.g., a cream composition) containing an active cosmetic material (e.g., a deodorant active, an antiperspirant active, a sunscreen, an insect repellent and/or an anti-fungal agent) and a silicone gel material. The silicone gel material includes (a) a volatile silicone material and (b) an organopolysiloxane material as a gelling agent, able to form a gel after being mixed with the volatile silicone material. The organopolysiloxane material can be a reaction product of a vinyl-terminated siloxane polymer and a hydride cross-linking agent. The composition can be formed by mixing the active cosmetic material and silicone gel material at ambient temperature. The compositions do not need particulate or clay thickeners or waxy gelling agents.
Abstract:
A high efficacy antiperspirant/deodorant stearyl alcohol free stick product may be made by combining: (a) 30-70 % volatile cyclomethicone; (b) 10-25 % of an antiperspirant active; (c) 1-15 % of an emollient; (d) 1-14 % of polyethylene comprising one or more members selected from the group consisting of homopolymers and copolymers of polyethylene wherein the polyethylene (i) is at least 90 % linear; (ii) has a molecular weight in the range of 300-3000 (especially 300-1000 and more especially 300-500); (iii) has a melting point in the range of 50-129 degrees C; and (iv) has a polymer backbone of CH3CH2-(CH2-CH2)n-H, where n is an average number and is selected to be in the range of 10-106; (e) 0.3-7 % of a wax as a co-gellant with the polyethylene wherein the wax has a melting point in the range of 40-97 degrees C; and (f) 1-40 % of an elastomer in cyclomethicone composition; provided that the ratio of wax:polyethylene is in the range of 1:1-1:10.
Abstract:
This invention comprises low residue cosmetic compositions (especially underarm products) which are made by combining an active ingredient; a silicone gel material itself comprising an elastomer composition; and at least one selected surfactant having an HLB value in the range of 8-16. The compositions of this invention exhibit reduced or eliminated film formation when applied to the skin and increased availability of the active ingredient.

Abstract:
Disclosed is a clear cosmetic gel composition in the form of a water-in-oil emulsion, and methods of forming and of using the composition. The composition has a water-based phase containing water, a cosmetically active ingredient, and at least one coupling agent; and an oil-based phase containing a material having a refractive index in the range of 1.40 - 1.50, silicone fluids and an alkoxylated, alkyl substituted siloxane surface active agent (e.g., dimethicone copolyol). The composition has a refractive index in a range of 1.4026 to 1.4150. Where the cosmetically active ingredient is an antiperspirant active ingredient, the composition can be an antiperspirant gel (e.g., soft gel) composition. In the refractive index range of the present invention, increased amounts of, e.g., antiperspirant active ingredient, and other high-refractive-index materials providing cosmetic benefits, can be incorporated in the water and oil phases of the composition while still achieving a clear composition. The composition can also include polypropylene glycols (e.g., tripropylene glycol), as part of the water-based phase, to provide a composition having reduced tackiness and reduced whitening (decreased residue); this composition is also mild (reduced skin irritation potential) relative to comparable commercial products.
