Background of the Invention

There is 2 continuing trend to develop new and superior cosmetic compositions especially for the reduction and/or elimination of wetness and/or odor under the arms.

Particular efforts include developing lower residue products especially with improved efficacy and aesthetics. Various product forms have included sticks (especially gel/sticks), gels, soft solids, roll-ons, aerosols and creams. Of these various forms the sticks, gels, soft solids creams and roll-ons ‘are made with a liquid base material incorporating a solidifying agent and/or gelling agent and/or thickening agent.

Generally, these forms include a solution of the cosmetically active ingredient in a suitable vehicle, a suspension of the active ingredient in a carrier vehicle, or a multiphasic dispersion or emulsion in which a solution of the active ingredient is dispersed or suspended in some continuous phase or in which the solubilized active ingredient constitutes the continuous phase.

A variety of soft-solid formulations are known. These include formulations made with the following ingredients: (a) clay thickening agent and an activator for the clay: for example, U.S. Patent

Number 5,019,375 to Tanner et al; and U.S. Patent Number 4,526,780 to Marschner et al; (b) particulate thickening agents such as fumed silica: for example, U.S. Patent

Number 5,069,897 to Orr; and U. S. Patent Number 4,937,069 to Shin; (c) selected volatile and/or non-volatile alkylmethylsiloxanes such as those including a structuring wax: for example, U.S. Patent Number 5,225,188 to Abrutyn et al; and PCT applications WO 97/16161 and 16162 both of which are assigned to

Unilever PLC; and (d) triglyceride gellants such as the glyceryl tribehenate described in U.S. Patent

Number 5,718,890 to Putnam et al. ) The use of a class of compositions known as silicone elastomers in cosmetic " compositions has shown some interesting results. PCT case WO 97/44010 and ’ 35 . assigned to the same assignee as this application describes a silicone gel material made by combining (a) a volatile silicone material and (b) an organopolysiloxane material (or silicone elastomer) as a gelling agent wherein the organopolysiloxane material (silicone elastomer) can be a reaction product of a vinyl-terminated siloxane polymer and a silicon hydride cross-linking agent. Related technology is also disclosed in PCT case

WO 98/00097, WO 98/00104 and 98/00105 assigned to Unilever PLC on cross-linked non-emulsifying elastomers. ‘ 5 U.S. Patent 5,599,533 to Stepniewski et al assigned to Estee Lauder describes a , stable water-in-oil emulsion system formed with an organopolysiloxane elastomer, a vehicle in which the elastomer is dispersed or dispersible, a stabilizing agent , a - surfactant and an aqueous component. A commercial product known as “REVELATION” retexturizing complex for hands and chest sold by the same assignee contains a silicone gel material with an organopolysiloxane component and octamethylcyclotetrasiloxane. :

EP 0 787 758 Al teaches a method for solvent thickening by using a silicone latex having a plurality of crosslinked polysiloxane particles.

Another recent case assigned to the same assignee as this application is WO 99/51192 and U.S. Patent Application Serial Number 9/273152 which describes antiperspirant compositions with the use of broad categories of elastomers. Other examples of the use of elastomer type materials and/ or methods for processing such materials may be found in PCT cases WO 98/00097; WO 98/00104; WO 98/00105;

WO 98/18438; WO 98/42307 all of which are incorporated herein by reference.

Two major problems have been observed when the use of elastomer materials is included in soft solid formulations. The first problem is reduction in efficacy due to the formation of an occlusive elastomeric film which prevents the active from diffusing into the sweat duct. The second problem is the consistency of the product as evidenced by high viscosity and elastic behavior when applied to the surface of the skin. In order to reduce this high viscosity, emollients and solvents have to be added which may negatively impact efficacy of the deodorant and/or antiperspirant. It has been found . that the use of a selected type of elastomer in soft solid formulations in combination with polyethylene beads as described herein overcomes these problems.

Thus, it is an object of the invention to provide improved cosmetic compositions with the improvements as previously described and which are useful as antiperspirants and/or deodorants. These and other objects of the invention will be apparent from the following description of the invention.

The antiperspirant active can be selected from the group consisting of any of the known antiperspirant active materials. These include, by way of example (and not of a limiting nature), aluminum chlorohydrate, aluminum chloride, aluminum sesquichlorohydrate, zirconyl hydroxychloride, aluminum-zirconium glycine complex (for example, aluminum zirconium trichlorohydrex gly, aluminum zirconium pentachlorohydrex gly, aluminum zirconium tetrachlorohydrex gly and aluminum zirconium octochlorohydrex gly), aluminum chlorohydrex PG, aluminum chlorohydrex

PEG, aluminum dichlorohydrex PG, and aluminum dichlorohydrex PEG. The aluminum-containing materials can be commonly referred to as antiperspirant active aluminum salts. Generally, the foregoing metal antiperspirant active materials are antiperspirant active metal salts. In the embodiments which are antiperspirant compositions according to the present invention, such compositions need not include aluminum-containing metal salts, and can include other antiperspirant active materials, including other antiperspirant active metal salts. Generally, Category I active antiperspirant ingredients listed in the Food and Drug Administration's Monograph on . antiperspirant drugs for over-the-counter human use can be used. In addition, any new drug, not listed in the Monograph, such as aluminum nitratohydrate and its combination . 35 with zirconyl hydroxychlorides and nitrides, or aluminum-stannous chlorohydrates, can : be incorporated as an antiperspirant active ingredient in antiperspirant compositions according to the present invention. _7-

Particular types of antiperspirant actives include aluminum zirconium trichlorohydrex and aluminum zirconium tetrachlorohydrex either with or without glycine. A particular antiperspirant active is aluminum trichlorohydrex gly such as

AZ7-902 SUF (from Reheis Inc., Berkley Heights, NJ) which has 98% of the particles 8 less than 10 micrans in size.

Antiperspirant actives can be incorporated into compositions according to the present invention in amounts in the range of 0.1 — 25% of the final composition, but the amount used will depend on the formulation of the composition. For example, at amounts in the lower end of the broader range (for example, 0.1 - 10% on an actives basis), a deodorant effect may be observed. At lower levels the antiperspirant active material will not substantially reduce the flow of perspiration, but will reduce malodor, for example, by acting as an antimicrobial material. At amounts of 10-25% (on an actives basis) such as 15 - 25%, by weight, of the total weight of the composition, an antiperspirant effect may be observed.

The antiperspirant active material is desirably included as particulate matter suspended in the composition of the present invention in amounts as described above, but can also be added as solutions or added directly to the mixture.

The polyethylene beads useful with this invention have a density in the range of 0.91-0.98 g/cm’ and a particle size in the range of 5-40 microns, with one particular type of polyethylene having a particle size of 20 microns. All particle sizes are averages. Several types of suitable polyethylene beads that are commercially available are MICROTHENE FN 510 from Equistar Chemicals LP (Houston, Texas); ACUMIST

A-6 from Allied Signal Corp., Morristown, NJ), and Performalene™ (New Phase

Technology, Piscataway, NJ). It is believed that the polyethylene component contributes to the reduction in syneresis and is also responsible for giving the products a powdery feel as determined by trained sensory panels.

Suitable antimicrobial agents include, for example, bacteriostatic quaternary ammonium compounds such as 2-amino-2-methyl-1-propanol (AMP), cetyl- trimethylammonium bromide, cetyl pyridinium chloride, 2, 4, 4’-trichloro-2’- hydroxydiphenylether (Triclosan), N-(4-chlorophenyl)-N’-(3,4-dichlorophenyl)urea (Triclocarban), silver halides, octoxyglycerin (Sensiva™ SC 50) and various zinc salts (for example, zinc ricinoleate). The bacteriostat can, illustratively, be included in the . composition in an amount of 0-5%, particularly 0.01-1.0% by weight, of the total weight of the composition. Triclosan, can illustratively be included in an amount of } 35 from 0.05% to about 0.5% by weight, of the total weight of the composition. -

A variety of fragrances can be used in these compositions if a scented products is desired. Fragrances can be used in an amount in the range of 0-5%, particularly 0.01- -2.0%, and, for example, at a level of 1%. . Masking agents can be used in an amount of 0.05-5.0% (particularly 0.05-2%) by weight based on the total weight of the composition if an unscented product is , desired.

Other various optional components include those described in U.S. Patents

Numbers 5.019.375 to Tanner et al; 4,937,069 to Shin; and 5,102,656, each of which is incorporated by reference in its entirety herein. Examples of such additional ingredients include fragrances, coloring agents, opacificers, etc. in types and amounts conventionally used for such products.

These compositions are soft solids made as suspensions and thickened or gelled by the elastomer component. While other thickeners may be used, the compositions of this invention will normally use the elastomer component as the only gellant. Of course various viscosities for a soft solid may be made depending on the amount of elastomer material and the amount of other ingredients used. One group having a more viscous form will have a viscosity in the range of 25,000-2,000,000 centipoise, particularly 50,000 — 1,000,000 centipoise, and suitable for use with an applicator with porous openings or slots such as those described in USSN 9/191,897 (PCT 99/25570) incorporated by reference herein as to the description of the applicators. Another form will have a lower viscosity such as in the range of 20,000-200,000 centipoise and will be suitable for use with applicators requiring a thinner composition, for example roll-on applicators which have a rolling ball structure. For example, such roll-on applicators are described in U.S. Patents Numbers 5,158,385 and 4,984,921. incorporated by reference herein as to the description of the applicators. : While various forms have been described, it is believed that the compositions made according to this inventions should preferably have a ratio of elastomer to antiperspirant active in the range of 1:2-1:20 in order to achieve the optimum improved efficacy and the improved stability that has been observed.

Compositions according to the present invention can be made by mixing the silicone gel material with surfactant(s) , active ingredient(s) and optionally one or more of emollient(s), thickener(s) and fragrance. Mixing conditions and the use of heating will depend on what types of materials are being combined and; the melting points for those materials as are known to those skilled in the art. For example if soft solids, roll- : 35 ons or gels are being made, temperatures, in the range of room temperature or slightly higher (for example, 25-50 degrees C, particularly 23-30 degrees C) may be used. For stick products and soft solid/cream products made with higher melting point materials

(for example, high temperature waxes) temperatures from 25-85 degrees C may be used. The mixture can be introduced into dispensing containers known to those skilled in the art including those for solids, gels, roll-ons, soft solids and creams. In one particular example, slotted dispensers may be used such as those known in the art, for example, those having a parallel Tow or rows of straight or curved slots or holes with a screw mechanism for forcing the composition through the top as the product is used.

Where the dispensing containers have a top surface with slots therein, the composition can be rubbed onto the skin from the top surface of the container (itself fed from a reservoir of product in the container) so as to deposit an adequate amount of the cosmetic composition on to the skin. The cosmetic composition, for example, an antiperspirant and/or deodorant in the form of a soft solid, can be extruded from inside the dispensing container through the slots or holes onto the top of the surface of the dispensing container, and from there may be applied to the skin in the axillary regions to deposit sufficient amounts of antiperspirant and/or deodorant active material to reduce body malodor and/or reduce perspiration in axillary regions of the human body.

Various forms of the invention can be exemplified by the following formulations but should not be construed as limitations on the invention:
