Anhydrous cosmetic compositions containing resveratrol derivatives

Abstract

An anhydrous color cosmetic composition comprising at least one resveratrol derivative and particulates; and an anhydrous emulsion skin care composition.

Description

TECHNICAL FIELD

The invention is in the field of anhydrous cosmetic compositions for application to keratinous surfaces such as skin, hair, or nails, for purposes of coloring or treating the surface.

BACKGROUND OF THE INVENTION

Resveratrol, also referred to as 3,5,4′-trihydroxystilbene, is a polyhydroxy-substituted compound having the general formula:

It is present in red grapes, raspberries, blueberries, and certain other plant berries or extracts. It has been reported that resveratrol has anti-aging, anti-cancer, and antiviral effects. Because of its perceived fountain-of-youth properties, resveratrol has been incorporated into a variety of cosmetic formulations, such as skin creams. However, one problem with resveratrol is that it is generally unstable in cosmetic formulations. Accordingly, if used in cosmetic formulas, it can only be used in very small amounts. If present in too large an amount, the resveratrol will hydrolyze and cause the cosmetic formulation into which it is incorporated to become discolored.

One way to address the instability of resveratrol is to derivatize the resveratrol by substituting the hydroxy groups at the 3, 5, and 4′ position with other functional groups to form resveratrol derivatives that are more stable in cosmetic formulas. It has been discovered that resveratrol derivatives of inorganic acids, organic carboxylic acids, mono-, -di, or polysaccharides, or other functional groups are more stable in cosmetic formulations, particularly those in the emulsion form.

It is an object of the invention to provide anhydrous cosmetic compositions containing at least one resveratrol derivative.

It is a further object of the invention to provide an anhydrous cosmetic composition containing at least one resveratrol derivative in an anhydrous emulsion form.

It is a further object of the invention to provide anhydrous color cosmetics that are aesthically pleasing and stable compositions that are commercially acceptable, that is, suitable for use by and sale to discriminating consumers that have high standards.

It is a further object of the invention to provide anhydrous cosmetic compositions in the form of liquids, solids, or semi-solids, or anhydrous emulsions, containing at least one resveratrol derivative.

SUMMARY OF THE INVENTION

The invention is directed to an anhydrous cosmetic composition comprising at least one resveratrol derivative.

The invention is further directed to an anhydrous emulsion cosmetic composition comprising at least one resveratrol derivative.

DETAILED DESCRIPTION

The compositions of the invention may be in the liquid, solid, or semi-solid form. The compositions may also be in the form of non-aqueous, or anhydrous, emulsions. Anhydrous emulsions are formed when the resveratrol derivative is solubilized or dispersed in a polar non-aqueous solvent such as ethanol, propylene glycol, butylene glycol, and the like. The compositions of the invention may be in the form of lipsticks, blush, eyeshadow, mascara, eyeliner, lipliner, nail color, skin treatment serums or gels, and the like.

I. Resveratrol Derivatives

Without being bound by this explanation, it is believed that the practical use of resveratrol in cosmetic compositions has been limited by instability due to the phenol groups. The resveratrol derivatives used in the compositions of the invention contain protective groups, which function to stabilize the phenol groups of resveratrol and make the resveratrol derivative suitable for use in emulsions where superior aesthetics and stability are required for commercially acceptable products. In addition, once the compositions containing the derivative is applied to skin, the protective groups can be easily hydrolyzed from the molecule, preferably by enzymes and other ingredients on the skin surface, to release an active form of resveratrol into the skin.

The resveratrol derivatives of the present invention have a general formula of:

wherein X, Y, and Z are either hydrogen or a protective group, provided that at least one of X, Y, and Z is the protective group.

The resveratrol derivatives may be present ranging from about 0.001 to 95%, preferably from about 0.005 to 90%, more preferably from about 0.1 to 20% by weight of the total composition.

A. Resveratrol Esters of Inorganic or Organic Acids

Resveratrol esters of inorganic acids, in which one or more of the X, Y, and Z are inorganic acid functional groups such as phosphates, nitrates, sulfonates, and carbonates, can be used in the present invention. Following is a list of exemplary inorganic acid esters that are particularly suitable for practice of the present invention:

3-phosphate-5,4′-dihydroxystilbene;

5-phosphate-3,4′-dihydroxystilbene;

4′-phosphate-3,5-dihydroxystilbene;

3,5-diphosphate-4′-hydroxystilbene;

3,4′-diphosphate-5-hydroxystilbene;

4′,5-diphosphate-3-hydroxystilbene;

3,5,4′-triphosphate stilbene;

3-nitrate-5,4′-dihydroxystilbene;

5-nitrate-3,4′-dihydroxystilbene;

4′-nitrate-3,5-dihydroxystilbene;

3,5-dinitrate-4′-hydroxystilbene;

3,4′-dinitrate-5-hydroxystilbene;

4′,5-dinitrate-3-hydroxystilbene;

3,5,4′-trinitrate stilbene;

3-sulfonate-5,4′-dihydroxystilbene;

5-sulfonate-3,4′-dihydroxystilbene;

3,5-dicarbonate-4′-hydroxystilbene;

3,4′-dicarbonate-5-hydroxystilbene;

4′,5-dicarbonate-3-hydroxystilbene; and

3,5,4′-tricarbonate stilbene.

Pharmaceutically acceptable salts of the above-listed resveratrol esters can also be used in the cosmetic compositions of the present invention. Such salts may include one or more monovalent or divalent cations selected from the group consisting of Na, K, Mg, Ca, Fe, and NH₄. The salts can be formed by adding corresponding bases, such as sodium hydroxide, potassium hydroxide, and the like, into a solution containing the resveratrol esters.

Such inorganic acid esters of resveratrol may be readily formed by well known chemical processes that substitute the hydroxyl groups of phenols or polyphenols with the phosphate, sulfonates, and carbonate functional groups. For example, U.S. Pat. No. 4,003,966 describes a one-step process for selectively phosphorylating phenols to form phosphate esters thereof, the contents of which are incorporated herein by reference in their entireties for all purposes.

Preferred is the 3,4′,5-triphosphate stilbene, also referred to as a resveratrol triphosphate ester having the formula (resveratrol triphosphate):

Phosphate esters of resveratrol, including resveratrol triphosphate, are disclosed in International Patent Application Publication No. WO 2006/029484A1, which is hereby incorporated by reference in its entirety. Resveratrol triphosphate may be synthesized by the method as set forth in Example 2 of WO 2006/029484A1. More specifically, a solution of resveratrol (3,4,5-trihydroxystilbene) (25 mmols, 5.7 grams) and dimethylaminopyridine (7.5 mmols, 0.93 grams) in 100 ml acetonitrile is cooled under nitrogen up to −10° C. After 10 minutes, carbon tetrachloride (375 mmol, 36.2 ml) and DIEA (159 mmol; 27.7 ml) and the mixture maintained under stirring for 30 minutes. Dibenzylphosphate (113 mmols, 25.0 ml) is added and the mixture stirred for an additional 12 hours at room temperature. The course of the reaction is monitored by TLC (silica F254, eluent ethyl acetate/n-hexane 80/20 v/v). One liter of 0.5 M KH2PO4 is added, and the mixture then extract with ethyl acetate. The resulting product, tri(dibenzylphosphate) resveratrol, is purified by filtration on a silica gel, washing first with a mixture of ethyl acetate/n-hexane (80/20 v/v) to remove any remaining unreacted resveratrol, and then with methanol, to obtain a yellow oil.

To the tri(dibenzylphosphate) resveratrol (12.5 mmol) in 200 mL of anhydrous DCM at 0° C., is added bromomethylsilane (79 mmols, 10.4 mL). After 2 hours, 300 mL of H₂O is added, and the reaction mixture is stirred for 1 hour. The water phase is washed again with ethyl acetate, then lyophilized to obtain an orange oil.

To the product obtained above, solubilized in 400 mL of ethanol, is added CH₃ONa (37 mmol; 2.03 g) and the reaction stirred for 12 hours at room temperature. The ethanol is evaporated in a rotavapor, and the residue solubilized in H₂O. The water phase is washed with ethyl acetate and lyophilized. The mass spectrum of the resulting white solid shows the presence of resveratrol triphosphate (PM=468.1), with a total yield of >90% with respect to resveratrol.

If desired the resveratrol triphosphate may be neutralized with organic or inorganic bases such as sodium hydroxide, potassium hydroxide and the like. Particularly preferred is where the resveratrol triphosphate is neutralized with sodium hydroxide to form trisodium resveratrol triphosphate.

In one preferred embodiment, the R group is a straight or branched chain fatty, or C_6-30, saturated or unsaturated alkyl group.

Exemplary carboxylic acids that can be used to form ester of resveratrol include, but are not limited to: substituted or unsubstituted saturated monocarboxylic acids, such as acetic acid, propionic acid, butyric acid (C4), valeric acid, hexanoic acid, caprylic acid (C8), lauric acid, stearic acid (C18), isostearic acid (branched C18), linoleic acid, linolenic acid, myristic acid (C14), arachidic acid (C20), arichidonic acid, erucic acid, behenic acid (C22), lauric acid (C12), capric acid (C10), caproic (C6), and palmitic acid (C16); or carboxylic acids substituted with cyclic disulfide groups, e.g. lipoic acid; or unsaturated monocarboxylic acids, such as acrylic acid, methacrylic acid, sorbic acid, oleic acid, linoleic acid, linolenic acid, docosahexaenoic acid, and eicosapentaenoic acid; amino acids, such as arginine, glutamine, and tyrosine; keto acids, such as pyruvic acid and acetoacetic acid; aromatic carboxylic acids, such as ascorbic acid, benzoic acid, salicylic acid, and ferulic acid; di- and tri-carboxylic acids, such as oxalic acid, malonic acid, malic acid, succinic acid, and glutaric acid. Also suitable are esters of carboxylic acids having cyclic disulfide substitutions, for example lipoic acid. The designation “C” followed by a number indicates the number of carbon atoms in the alkyl chain.

III. Structuring Agents

It is often desirable to structure, or increase the viscosity of anhydrous compositions, particular those found in the semi-solid or solid form. In the case where the composition is in the anhydrous emulsion form the structuring agent may be found in the nonaqueous polar solvent phase. Alternatively where the composition comprises a lipophilic oil phase, the structuring agent may be found in the oil phase. The term “oil phase structuring agent” means an ingredient or combination of ingredients, soluble or dispersible in the oil phase, which will increase the viscosity, or structure, the oil phase. The term “nonaqueous phase structuring agent” means an ingredient or combination of ingredients, soluble or dispersible in the nonaqueous polar solvent phase, if present, that will increase the viscosity or structure the nonaqueous polar solvent phase of the composition. The structuring agent used should be compatible with the resveratrol derivative and the rest of the formulation ingredients. The term “compatible” means that the structuring agent and resveratrol derivative are capable of being formulated into a cosmetic product that is generally stable. The structuring agent may be present in an amount sufficient to provide a liquid composition with increased viscosity, a semi-solid, or in some cases a solid composition that may be self-supporting. The structuring agent itself may be present in the liquid, semi-solid, or solid form. Suggested ranges of structuring agent are from about 0.01 to 70%, preferably from about 0.05 to 50%, more preferably from about 0.1-35% by weight of the total composition. Suitable oil phase structuring agents include those that are silicone based or organic based. They may be polymers or non-polymers, synthetic, natural, or a combination of both.

A variety of oil phase structuring agents may be silicone based, such as silicone elastomers, silicone gums, silicone waxes, linear silicones having a degree of polymerization that provides the silicone with a degree of viscosity such that when incorporated into the cosmetic composition it is capable of increasing the viscosity of the oil phase. Examples of silicone structuring agents include, but are not limited to:

(a). Silicone Elastomers

Silicone elastomers suitable for use in the compositions of the invention include those that are formed by addition reaction-curing, by reacting an SiH-containing diorganosiloxane and an organopolysiloxane having terminal olefinic unsaturation, or an alpha-omega diene hydrocarbon, in the presence of a platinum metal catalyst. Such elastomers may also be formed by other reaction methods such as condensation-curing organopolysiloxane compositions in the presence of an organotin compound via a dehydrogenation reaction between hydroxyl-terminated diorganopolysiloxane and SiH-containing diorganopolysiloxane or alpha omega diene; or by condensation-curing organopolysiloxane compositions in the presence of an organotin compound or a titanate ester using a condensation reaction between an hydroxyl-terminated diorganopolysiloxane and a hydrolysable organosiloxane; peroxide-curing organopolysiloxane compositions which thermally cure in the presence of an organoperoxide catalyst.

One type of elastomer that may be suitable is prepared by addition reaction-curing an organopolysiloxane having at least 2 lower alkenyl groups in each molecule or an alpha-omega diene; and an organopolysiloxane having at least 2 silicon-bonded hydrogen atoms in each molecule; and a platinum-type catalyst. While the lower alkenyl groups such as vinyl, can be present at any position in the molecule, terminal olefinic unsaturation on one or both molecular terminals is preferred. The molecular structure of this component may be straight chain, branched straight chain, cyclic, or network. These organopolysiloxanes are exemplified by methylvinylsiloxanes, methylvinylsiloxane-dimethylsiloxane copolymers, dimethylvinylsiloxy-terminated dimethylpolysiloxanes, dimethylvinylsiloxy-terminated dimethylsiloxane-methylphenylsiloxane copolymers, dimethylvinylsiloxy-terminated dimethylsiloxane-diphenylsiloxane-methylvinylsiloxane copolymers, trimethylsiloxy-terminated dimethylsiloxane-methylvinylsiloxane copolymers, trimethylsiloxy-terminated dimethylsiloxane-methylphenylsiloxane-methylvinylsiloxane copolymers, dimethylvinylsiloxy-terminated methyl(3,3,3-trifluoropropyl)polysiloxanes, and dimethylvinylsiloxy-terminated dimethylsiloxane-methyl(3,3,-trifluoropropyl)siloxane copolymers, decadiene, octadiene, heptadiene, hexadiene, pentadiene, or tetradiene, or tridiene.

Curing proceeds by the addition reaction of the silicon-bonded hydrogen atoms in the dimethyl methylhydrogen siloxane, with the siloxane or alpha-omega diene under catalysis using the catalyst mentioned herein. To form a highly crosslinked structure, the methyl hydrogen siloxane must contain at least 2 silicon-bonded hydrogen atoms in each molecule in order to optimize function as a crosslinker.

The catalyst used in the addition reaction of silicon-bonded hydrogen atoms and alkenyl groups, and is concretely exemplified by chloroplatinic acid, possibly dissolved in an alcohol or ketone and this solution optionally aged, chloroplatinic acid-olefin complexes, chloroplatinic acid-alkenylsiloxane complexes, chloroplatinic acid-diketone complexes, platinum black, and carrier-supported platinum.

G. Film Formers

It may be desirable to include one or more film forming ingredients in the cosmetic compositions of the invention. Suitable film formers are ingredients that contribute to formation of a film on the keratinous surface. In some cases the film formers may provide films that provide long wearing or transfer resistant properties such that the cosmetic applied to the keratinous surface will remain for periods of time ranging from 3 to 16 hours. If present, such film formers may range from about 0.01 to 50%, preferably from about 0.1 to 40%, more preferably from about 0.5 to 35% by weight of the total composition. The film formers are most often found in the polymeric form and may be natural or synthetic polymers. If synthetic, silicone polymers, organic polymers or copolymers of silicones and organic groups may be acceptable.

1. Silicone Resins

One particularly suitable type of silicone film former is a silicone resin. Silicone resins are generally highly crosslinked structures comprising combinations of M, D, T, and Q units. The term “M” means a monofunctional siloxy unit having the general formula:[Si—(CH₃)₃—O]_0.5 In cases where the M unit is other than methyl (such as ethyl, propyl, ethoxy, etc.) the M unit may have a prime after it, e.g. M′.

The term “D” means a difunctional siloxy unit having the general formula:[Si—(CH₃)₂—O]_1.0 The difunctional unit may be substituted with alkyl groups other than methyl, such as ethyl, propyl, alkylene glycol, and the like, in which case the D unit may be referred to as D′, with the prime indicating a substitution.

The term “T” means a trifunctional siloxy unit having the general formula:[Si—(CH₃)—O]_1.5 The trifunctional unit may be substituted with substituents other than methyl, in which case it may be referred to as T′.

The term “Q” refers to a quadrifunctional siloxy unit having the general formula:[Si—O—]_2.0

The silicone resins that may be used as film formers in the compositions of the invention preferably comprise highly crosslinked combinations of M, T, and Q units. Examples of such resins include trimethylsiloxysilicate which can be purchased from Dow Corning Corporation as 749 Fluid, or from GE Silicones under the SR-1000 tradename. Also suitable is a silicone resin that contains a large percentage of T groups, such as MK resin sold by Wacker-Chemie, having the CTFA name polymethylsilsesquioxane.

2. Copolymers of Silicone and Organic Monomers

Also suitable for use as the film formers are copolymers of silicone and organic monomers such as acrylates, methacrylates, and the like. Examples of such suitable film forming polymers include those commonly referred to as silicone acrylate or vinyl silicone copolymers, such as those sold by 3M under the brand name “Silicone Plus” polymers such as SA-70, having the CTFA name Polysilicone-7 and is a copolymer of isobutylmethacrylate and n-butyl endblocked polydimethylsiloxane propyl methacrylate; or VS-70 having the CTFA name Polysilicone-6, which is a copolymer of dimethylsiloxane and methyl-3 mercaptopropyl siloxane reacted with isobutyl methacrylate; or VS-80, having the CTFA name Polysilicone-8, which has the general structure:

Where R represents the acrylates copolymer radical.

3. Organic Polymers

Also suitable as film formers include various types of organic polymers such as polymers formed from acrylic acid, methacrylic acid, or their simple C_1-10 carboxylic acid esters, such as methyl methacrylate, methyl acrylate, and the like.

4. Natural Polymers

Also suitable are various types of natural polymers such as shellac, natural resins, chitin, and the like.

V. The Cosmetic Compositions

The anhydrous cosmetic compositions of the invention may be found in the form of anhydrous emulsions, serums, or gels; or color cosmetic products such as mascara, blush, lipstick, eyeshadow, eyeliner, brow color, an the like. The resveratrol derivative may be found in the oil phase. If the composition is found in the form of an anhydrous emulsion, the resveratrol derivative may also be dispersed or solubilized in the nonaqueous polar solvent phase of the anhydrous emulsion. For example, certain hydrophilic derivatives such as resveratrol triphosphate, resveratrol trisulfonate, and the like are generally hydrophilic in nature, and will better disperse or solubilize in the nonaqueous polar solvent phase of an anhydrous emulsion. On the other hand, such hydrophilic derivatives may also be dispersed in an anhydrous composition in the oil phase, in some cases with the use of amphiphilic materials. Certain other resveratrol derivatives are lipophilic in nature and can be easily dispersed or solublilized in the oil phase of the anhydrous composition, if desired.

Typical color cosmetic compositions such as foundations, blush, eyeshadow and the like will preferably contain from about 1-85% oil, from about 1 to 90% structuring agent, and from 0.1 to 65% of particulates that are pigments or a combination of pigments and powders. Optionally, the compositions may comprise from about 0.1 to 25% surfactant.

Typical anhydrous lash or brow color compositions contain from about 1-98% oil, 1-85% structuring agent, and from about 0.1 to 85% particulates.

Typical anhydrous emulsion compositions of the invention comprise from about 0.1 to 75% of a nonaqueous polar solvent, 0.1 to 50% structuring agent. They may be found in the form of serums, gels, or creams.
