Abstract

The subject matter disclosed herein comprises a sweat-controlling, water-absorbent cosmetic product. The cosmetic product comprises a base formulation, and a sweat-absorbent complex comprising: (a) at least one water-absorbing component, (b) at least one surfactant, (c) at least one electrolyte selected from the group consisting of antiperspirant salts comprising aluminum halides, Aluminum hydroxy halides, zirconium oxyhalides, zirconyl hydroxy halides, and mixtures of these materials, and (d) at least one solvent and / or at least one carrier.

Description

area

The embodiments of the invention disclosed herein relate to embodiments of antiperspirants and deodorants and to embodiments of methods of making antiperspirants and deodorants.

background

Cosmetic products designed to treat transpiration include deodorants and antiperspirants. Deodorants eliminate unpleasant odors resulting from the bacterial decomposition of perspiration. Deodorants therefore often contain both antibacterial substances and fragrant substances such as aromatic essences. Many essential oils have both antibacterial and fragrant properties, which is why they are often used in deodorants.

Antiperspirants inhibit sweat production. Antiperspirants contain astringents as active ingredients, antiperspirant active substances, in particular aluminum or zirconium salts. An adtring type, transparent antiperspirant, has gained popularity due to its aesthetic appearance. This generation of antiperspirants typically includes emulsions with propylene glycol, astringents, water and oils. This type of antiperspirant is less effective than a conventional antiperspirant because of the polymerization of the astringents.

Deodorant products contain water while conventional antiperspirants in a nonpolar phase such as silicone oil or mineral oil are substantially free of water to prevent the polymerization of the astringents. The patent application WO 03/030853 discloses a substantially anhydrous forearm product containing a particular water-absorbing polymer, a volatile silicone and a gelling agent, and optionally, small amounts of a surfactant for stabilizing the formulation, antiperspirant active or deodorant, non-volatile silicone, and emulsifier. The product is a suspension wherein the water-absorbing polymer is in the form of dispersed particles. This formulation is not suitable for use in conventional hydrous deodorant formulations because the water-absorbing polymer swells in water, thereby losing its water storage capacity.

The subject matter disclosed herein comprises an embodiment of a hydrous, water-absorbent cosmetic product which comprising a sweat-absorbing complex, with the following components:

• i) a basic formulation, and
• ii) a sweat-absorbing complex comprising (a) at least one water-absorbing component, (b) at least one surfactant, (c) at least one electrolyte selected from the group containing antiperspirant salts, and (d) at least one solvent and / or or at least one carrier.

 The sweat-absorbing complex that is in the base formulation is in the form of emulsified particles. The particles comprise a three-dimensional, water-swellable network of the at least one water-absorbing component and are at least partially coated with the at least one surfactant. The antiperspirant salt electrolyte is at least partially embedded in the interstices of the three-dimensional network of the at least one water-absorbing component. Antiperspirant salts useful as astringent antiperspirant salts or as components of astringent complexes include aluminum halides, aluminum hydroxyhalides, zirconium oxyhalides, zirconyl hydroxyhalides, and mixtures of these materials.

Aluminum salts of this type include aluminum chloride and the aluminum hydroxyhalides having the general formula Al ₂ (OH) _x Q _y XH ₂ O where Q is chloro, bromo or iodo; where x is from about 2 to about 5, and x + y ≈ 6, and x and y need not be integers; and wherein X is from about 1 to about 6. Aluminum salts of this type can be prepared in the manner more fully described in U.S. Pat U.S. Patent No. 3,887,692 issued to Gilman on June 3, 1975, and U.S. Patent No. 3,904,741 , granted to Jones and Rubino on September 9, 1975.

The zirconium compounds useful in the present invention include both the zirconia salts and the zirconium hydroxy salts, also referred to as zirconyl salts and zirconyl hydroxy salts. These compounds can be represented by the following general empirical formula: ZrO (OH) ₂ - _nz B _z wherein z can vary from about 0.9 to about 2 and need not be an integer, n is the valency of B, 2-nz is greater than or equal to 0, and B can be selected from the group consisting of halides, nitrate, Sulfamate, sulfate, and mixtures thereof. Although only zirconium compounds are exemplified in this specification, it will be understood that other Group IVb metal compounds, including hafnium, can be used in the present invention.

Also included are oxo-hexameric zirconium octa-amino acid salts for antiperspirant and / or deodorant compositions which have a reduced tendency to form higher molecular weight zirconium complexes. These antiperspirant agents are in the US 7,897,799 further described.

Specific antiperspirant salts useful in the formulation embodiment include one or more of the following:
Aluminum zirconium tetrachlorohydrexglycine complex with zinc glycinate and aluminum zirconium tetrachlorohydrexglycine complex with a salt other than zinc glycinate and other water-soluble salts such as sodium arginate. Other effective solid antiperspirants include aluminum chlorohydrate, aluminum sesquichlorohydrate, aluminum zirconium trichlorohydrex glycine, aluminum zirconium pentachlorohydrex glycine, aluminum zirconium tetrachlorohydrex glycine, and aluminum zirconium octchlorohydrex glycine. The materials containing aluminum and zirconium are commonly referred to as antiperspirant aluminum-zirconium salts. In general, the foregoing antiperspirant metal-containing substances are antiperspirant metal salts listed in US Pat Federal Register, Vol. 68, No. 110, Monday, June 9, 2003, Rules and Regulations ,

Salts useful as astringent antiperspirant salts or as components of astringent complexes include aluminum halides, aluminum hydroxyhalides, zirconium oxyhalides, zirconyl hydroxyhalides, and mixtures of these materials.

The sweat-absorbing complex comprises a form of emulsified particles comprising a three-dimensional, water-swellable polymer network of the at least one water-absorbing component. The sweat-absorbing complex is at least partially coated with the at least one surfactant. Another embodiment comprises adding propylene glycol, dibenzylidene sorbitol and an antiperspirant salt such as an effective amino salt such as e.g. B. Aluminiumzirconiumtetrachlorhydrexglycin complex. Other amino acid salts include sodium arginate. Another embodiment comprises a mixture containing dibenzylidenesorbitol and adding an antiperspirant active to the mixture.

In the complex, the at least one water-absorbing component that does not fully swell in the solvent and / or carrier but can swell in water to form particles of a three-dimensional gel-like polymer network, prior to water absorption via a base formulation of the cosmetic product due to the layer of at least a surfactant protected. The layer of the at least one surfactant stabilizes the particles of the absorbent material, thereby maintaining its perspiration receptivity. In addition, the coating comprising the surfactant ensures a homogeneous suspension of the absorbent particles in the base formulation.

Upon application to the skin, the water contained in the base formulation vaporizes, causing the dehydrated product to form a thin film on the skin. As a result of this process, the surfactant remains between the skin and the water-absorbing component. The surfactant aids in the adhesion of the water-absorbing component to the skin by mediating the contact between the water-absorbing component and the skin, which allows the absorption of sweat by the particles. Due to the encapsulation, only a small portion of the water-absorbing component swells in the water of the formulation. Much of the water absorption capacity is available for sweat absorption. The increased sweat absorbency of the absorber material is retained over a longer period of time compared to conventional compositions.

The moisture-absorbing complex has excellent perspiration absorption capability, the particular advantage of moisture reduction. The complex is suitable for incorporation into a cosmetic product, especially in products such as antiperspirants and deodorants. The moisture absorbing complex is also useful in other products having water absorption properties such as diapers and towels.

Accordingly, embodiments of the invention disclosed herein include the sweat-absorbing complex having components having the following concentration ranges:

• (a) from 10 to 80%, preferably from 20 to 70%, and in some embodiments from about 30 to 50% of at least one water-absorbing component,
• (b) from 10 to 70%, preferably from 20 to 60%, and in some embodiments from about 30 to 45% of at least one surfactant,

• (d) optionally 0 to 50% of at least one solvent and / or at least one carrier.

 Specific concentration ranges depend on the properties of the individual components and the type of cosmetic product.

At least one water-absorbing component is substantially insoluble in the at least one solvent and / or carrier, but may swell in water without being completely dissolved in the water contained in a base formulation of a cosmetic product. It has a water absorption capacity of at least 20%, preferably 50%, based on its dry weight. The average particle size of the water-absorbing component in the complex ranges from 0.1 to 450 μm, preferably from 10 to 200 μm. Particles with a mean particle size between 50 and 100 microns show particularly good results.

Cosmetic products with the sweat-absorbing complex described herein include antiperspirants and deodorants, such as any sweat-controlling or deodorizing preparations, sticks, sprays, aerosols, creams, sunscreens, after shaves, lotions, foundation creams, and make-ups. An advantage of the complex of the invention is that it can easily be added to any base formulations without losing its water storage capacity. Typically, such products contain from 1 to 40% by weight of water, preferably from 3 to 20% by weight. Common deodorant products are single-phase formulations containing 12% by weight of water.

The sweat-absorbing complex is useful in cosmetic products in a broad concentration range of 0.05 to 99% by weight. Typically, the complex is included in a base formulation in a range of 0.1 to 10 weight percent, in some embodiments from 0.25 to 5 weight percent. In an antiperspirant or deodorant base formulation, the complex advantageously has a weight fraction between 0.1 and 10%, preferably about 1%. The actual antiperspirant or deodorant base formulation generally contains from 60 to 90% by weight, preferably from 70 to 80% by weight of at least one solvent, from 5 to 20%, preferably from 10 to 15% of water, and from 1 to 15%, preferably 5 to 8% of at least one gelling agent.

Some embodiments of cosmetic products also include adjuvants and / or agents, e.g. As pigments, dyes, antioxidants, preservatives, more moisture-retaining substances, plasticizers, fragrances such as aromatic essences, stabilizers, cell exchange promoters, cell proliferation stimulators, antiinflammatory agents, antimicrobials, hormone regulators, enzyme inhibitors, UV absorbers, sunscreens and the like, and mixtures thereof.

• (a) Mischen mindestens einer wasserabsorbierenden Komponente mit dem mindestens einen Elektrolyten,
• (b) Zugeben des mindestens einen Tensids unter Rühren und Erwärmen, bis ein homogenes Gemisch erhalten wird, und, bei Verwendung eines Lösungsmittels und/oder Trägers,
• (c) Zugeben des mindestens einen Lösungsmittels und/oder mindestens einen Trägers zu dem Gemisch von Schritt (b) und Mischen zur Bildung eines im Wesentlichen homogenen Gemisches.

The cosmetic product according to the embodiments disclosed herein comprises a coating of the absorbent particles of the sweat-absorbing complex with the at least one surfactant. This structure of the sweat-absorbing complex can be obtained by:

• (a) mixing at least one water-absorbing component with the at least one electrolyte,
• (b) adding the at least one surfactant with stirring and heating until a homogeneous mixture is obtained and, when using a solvent and / or carrier,
• (c) adding the at least one solvent and / or at least one carrier to the mixture of step (b) and mixing to form a substantially homogeneous mixture.

 The application of heat energy and shear forces, by stirring, in step (b) is critical in causing the cleavage of inter- and intramolecular bonds in the surfactant and in the water-absorbing component and in allowing the formation of new physical interactions, especially hydrophobic interactions and hydrogen bonds, between the at least one surfactant and the at least one water-absorbing component in the subsequent cooling process. Without the application of heat energy and shear forces, surfactant (s) and water-absorbing component (s) will form very weak physical interactions, and they will not be able to provide a cosmetic product with significant water absorption capacity, when added to a base cosmetic formulation. To prepare a cosmetic product, the sweat-absorbing complex thus prepared, which already contains the coated absorbent particles, is simply added to a suitable base formulation, in particular to a hydrous deodorant base formulation.

Suitable substances for the individual components of the sweat-absorbing complex are mentioned below.

Water-absorbing component

The at least one water-absorbing component is selected from any natural or synthetic polymers that can swell in water to form a three-dimensional gel-like network.

The water-absorbing components usable herein include gums or rubbery polymers. In the context of the embodiments disclosed herein, "gum" is broadly defined as a water-soluble polymer isolated from land or seaweed or microorganisms that can contribute to the viscosity and / or swellability of a dispersion thereof. The water-absorbing component is, in some embodiments, a gum derived from plant or microbial biosynthesis of terrestrial or marine organisms. Such gums essentially contain repeats of monosaccharide units and have relatively high molecular weights of at least 100,000 g / mol. Examples of preferred gums are guar gum (Cyamopsis tetragonolobus), guar derivatives, locust bean gum, cellulose gum, gum arabic, karaya gum, gum tragacanth, algae-derived gums (including agar, carrageenan, furcellaran and alginates), scleroglucan (sclerotium gum), tamarind seed gum, xanthan gum, Dextran gum, gellan gum, propylene glycol alginate and the like, as well as derivatives and mixtures thereof.

Another group of water-absorbing components are polysaccharides of plant origin, essentially comprising repeats of monosaccharide units of hexoses and / or pentoses. Specific examples include natural celluloses, natural fibers, cellulose derivatives, microcrystalline cellulose, carboxymethylcelluloses, methylcelluloses, hydroxyethylcelluloses, hydroxypropylcelluloses, hydroxypropylmethylcelluloses, pectins, maltodextrins, inulin, inulin derivatives, starch, starch derivatives, derivatives and mixtures thereof.

 Another group of suitable water-absorbing components is selected from chemically modified polysaccharides, in particular from the group comprising cellulose derivatives, starch derivatives, pectin derivatives, starch / acrylamide / sodium acrylate graft copolymers (starch graft polymers), and mixtures thereof.

According to a further embodiment of the invention, the at least one water-absorbing component is selected from polyacrylate-based synthetic polymers, essentially comprising repeats of acrylic acid, acrylamide, methacrylic acid, derivatives or mixtures thereof. Examples of such compounds include sodium polyacrylate, polyacrylamide, their copolymers and / or mixtures thereof.

Another group of water-absorbing components is selected from silicic acids (Si (OH) ₄ or SiO ₂ ) and any types of derivatives and modifications thereof. Suitable examples include condensation products thereof, ie, polysilicic acids ((SiO ₂ ) _m .nH ₂ O), silicic anhydride (silica, SiO ₂ ), fumed silica, hydrated silica (SiO ₂ .H ₂ O), silica gel, silicate esters, and / or silicate salts such as Sodium silicate, magnesium silicate and calcium silicate. It has been found that the degree of water uptake and the water absorption capacity of these silica components can be increased significantly by predispersing them in an oil phase prior to the preparation of the complex.

It is also possible to use mixtures of the above-mentioned water-absorbing components.

surfactants

As stated above, the at least one surfactant performs the function of forming a coating on the outer surface of the particles of the water-absorbing component (s), thereby affecting the surface properties thereof. In particular, the surfactants assist in keeping the polymer on the skin, protecting it from unwanted water uptake from the base formulation. Surfactants include compounds including monomers, dimers, trimers, oligomers, and polymers that have both lipophilic and hydrophilic functionalities of a strength sufficient to develop an affinity for both hydrophilic and lipophilic portions of the formulation. Such fabrics form aligned layers around the water-absorbing particles. In this way, the particles of the water-absorbing component (s) are stabilized and distributed homogeneously in the formulation.

For the purposes mentioned above, the surfactant has a so-called hydrophilic / lipophilic balance (HLB) of below 13, preferably in the range of 2 to 13 in some embodiments, in other embodiments of 3 to 11. Very good results are achieved with surfactants having one HLB ranging from 3 to 9, in some embodiments from 4 to 8. The HLB is a dimensionless size developed by C. Griffin that accounts for the relative amounts of lipophilic segments to hydrophilic segments of a material. The determination of the numerical values of the HLB is based on effects of the chemical groups within a molecule ( DL Courtney in "Surfactants in Cosmetics," 2nd Edition, Marcel Dekker, Inc., New York, 1997, 128-130 ). According to one embodiment of the invention, a mixture of at least two surfactants in the complex is used. In this case, it is also possible to use surfactants having HLB values outside the above-mentioned ranges, as far as an effective weight-average HLB of such a combination falls within the above-mentioned ranges.

The at least one surfactant, in some embodiments, is a nonionic, anionic, cationic or amphoteric compound or a combination thereof. Compound examples include fatty alcohols, ethoxylated alcohols, ethoxylated triglycerides, ethoxylated oils, monoglycerides, carboxylic acid esters of alkyl or alkenyl glycols, C ₁ -C ₄₀ fatty acid esters of polyols, C ₁ -C ₄₀ fatty acid ethers of polyols, C ₁ -C ₄₀ fatty acid esters of alkyl or alkenyl glycols, polyglycerol esters, polyglycerol esters of C ₁ -C ₄₀ fatty acids, hydrocarbyl-derived esters, sugar esters and polyesters, alkoxylated sugar esters and polyesters, ethoxylated carboxylic esters of C ₁ -C ₄₀ fatty acids, sorbitan or polysorbate esters of fatty acids, ethoxylated sorbitan esters of fatty acids, ethoxylated sugar ethers of fatty acids, alkoxylated derivatives of _C1-C40 fatty acid esters of _C1-C40 fatty alcohols, alkoxylated derivatives of C ₁ -C ₄₀ -Fettsäureethern of C ₁ -C ₄₀ fatty alcohols, Polyethylene glycol ethers, polyethylene glycol esters, ethoxylated polysiloxanes, alkyl glycosides, alkanolamides, amine oxides, cetyl phosphate, Kal iumetyl phosphate, diethanolamine cetyl phosphate, carboxylic acids and derivatives thereof, sulfonic acid derivatives, sulfuric acid derivatives, phosphoric acid derivatives, ethoxylated fatty ether phosphates, fatty acid amides, acyl lactylates, alkylamidoalkylamines, alkylamines, alkylimidazolines, alkyl substituted amino acids, and mixtures thereof. Specific examples are sucrose stearate and sorbitan sesquioleate and mixtures thereof.

electrolytes

The at least one antiperspirant electrolyte takes on the function of stabilizing the complex, in particular of the particles, and increasing the water absorption - by electrostatic repulsive interactions between the ions, forces between the polymer chains - and the osmotic pressure of the particles. In this way, the antiperspirant electrolytes retain the water within the particles and help maintain the stability and buildup of the particles.

The required percentages by weight of the electrolyte in the water-absorbing complex depend on the physical and chemical properties of the electrolyte and the other components.

Solvent / carrier

In some embodiments, a solvent and / or carrier is present in the sweat-absorbing complex. In general, this is only required in those cases where the at least one surfactant is a solid. In the case of a surfactant in the form of a liquid, neither a solvent nor a carrier is needed. The at least one solvent and / or the at least one carrier may be selected from the group comprising glycols, glycerol, polar and non-polar oils, hydrocarbons, ethers, esters, medium and long-chain alcohols, alkoxylated alcohols, polyhydric alcohols, polyols, and mixtures thereof , Specific examples include propylene glycol, dipropylene glycol, ethylene glycol, glycerol, diglycerol, diacetin, triacetin, isopropyl palmitate, isododecane, isohexadecane, triglycerides, mineral oil, and mixtures thereof.

Embodiments of the present invention disclosed herein are a combination of an aluminum salt-regulating aluminum salt control agent with the moisture-absorbing complex referred to. The embodiments provide a consumer with a particular advantage of regulating increased underarm wetness and unexpected, improved effectiveness. It was found that a formulation using 10% aluminum salt as the sole active ingredient showed an efficacy of moisture control of 20.25% in at least 50% of a tested population 72 hours after application. This result is consistent with the acceptable efficacy of an antiperspirant based on the FDA (USA) guidelines for testing the moisture regulation of an antiperspirant. A formulation was also tested which contained only the moisture-absorbing complex, not aluminum salt. This formulation showed a moisture control efficacy of 72% at least 50% of a population tested 72 hours after application. When testing a formulation containing both the moisture-absorbing complex discussed herein and 10% aluminum salt, the improved effect on consumers was a regulation of underarm wetness that was 80% to 36.08% compared to the aluminum salt alone formulation and with the moisture-absorbing complex alone was increased. The only changes in the formulations tested were the presence or absence of the aluminum salt and moisture complex factor.

Other embodiments of the invention may be derived from other features recited in the dependent claims.

The embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments may be utilized and changes to the formulation and method may be made without departing from the scope of the invention. The detailed description is not to be construed as limiting, and the scope of the invention will be defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled.

It will be understood by those skilled in the art that changes may be made to the embodiments described above without departing from the broad inventive concept thereof. It is therefore to be understood that this invention is not limited to the particular embodiments disclosed, but is intended to include changes within the spirit and scope of the present invention as defined by the present specification.
