An external preparation characterized by comprising, as selected from gallic acid derivatives of the following formula (I), 1
Description


TECHNICAL FIELD

[0001] This invention relates to a preparation for external use formulated with a gallic acid glucoside, and more particularly, to a preparation for external use that is applicable as a hair cosmetic wherein the gallic acid glucoside is suppressed from being precipitated and settled at low temperatures.



BACKGROUND ART

[0002] It is known that gallic acid and ester products thereof have the capabilities of skin whitening, antioxidation, impartment of stiffness and elasticity to hair and remedy of the hair damaged through coloring or by the action of a perm agent (remedy of F-layer and microfibrils). In fact, such a preparation has been expected for applications in various fields such as skin preparations for external use in the form of a cream or an emulsion, hair treatments such as hair styling agents or gels, and the like. However, gallic acid and its esters are usually poor in stability. In the course of actual preparation, a problem, which is coloration or precipitation, makes it difficult to show the functions or capabilities satisfactorily. In addition, some types of gallic acid esters are substantially insoluble in water, with the possibility that limitation is placed on the amount used.


[0003] In order to solve these problems, glucosylation of gallic acid and esters thereof wherein a saccharide is joined to the phenolic hydroxyl groups of gallic acid has been proposed (Japanese Patent Laid-open No. 2000-319116). Although such gallic acid glucosides are improved in solubility at normal temperatures, the solubility at low temperatures is so low that a problem arises in that when a solution of a gallic acid glucoside in water or a mixed solvent of water/polar organic solvent is allowed to stand at low temperatures, a precipitate is formed.


[0004] As described above, gallic acid glucosides are low in solubility in water or a mixed solvent of water/polar organic solvent at low temperatures, with the attendant problem that a precipitate settles.



DISCLOSURE OF INVENTION

[0005] An object of the invention is to provide a preparation for external use wherein gallic acid glucosides are suppressed from precipitating at low temperatures.


[0006] In order to achieve the above object, the present inventors have made intensive studies on gallic acid glucosides being suppressed from precipitating at low temperatures and, as a result, found that an external preparation having excellent low temperature stability is obtained by formulating gallic acid derivatives (A) and (B) of the following formula in the specific amounts, and preferably further formulating a cationic surface active agent. The invention has been accomplished based on the above finding.


[0007] The invention provides an external preparation, which is characterized by including, as selected from gallic acid derivatives of the following formula (I),
2


[0008] wherein R1 represents a hydrogen atom, an alkali metal, an alkaline earth metal, an ammonium salt, or an alkyl or alkenyl group having from 1 to 18 carbon atoms; R2, R3, and R4 independently represent a hydrogen atom, an hydroxyl group, an alkoxy group having from 1 to 18 carbon atoms, a polyoxyethylene group, a polyoxypropylene group, or a residue of a monosaccharide, a disaccharide or an oligosaccharide; 90 wt % or over of one or more gallic acid derivatives (A) wherein two of R2, R3, and R4 in the formula (I) independently represent a residue of a monosaccharide, disaccharide, or oligosaccharide; from 0.001 wt % to less than 10 wt % of one or more gallic acid derivatives (B) wherein one of R2, R3 and R4 represents a residue of a monosaccharide, disaccharide, or oligosaccharide, each based on the total content of the gallic acid derivatives.







BEST MODE FOR CARRYING OUT THE INVENTION

[0009] The external preparation of the invention is suitably used, particularly, as hair cosmetics. The external preparation includes, selected among gallic acid derivatives of the following formula (I), 90 % (% by weight herein and whenever it appears hereinafter) or over of one or more gallic acid derivatives (A) of the formula (I) wherein two of R2, R3, and R4 independently represent a monosaccharide, disaccharide or oligosaccharide residue and from 0.001% to smaller than 10% of one or more gallic acid derivatives (B) of the formula (I) wherein one of R2, R3, and R4 represents a monosaccharide, disaccharide or oligosaccharide residue, each based on the total content of the gallic acid derivatives of formula (1).
3


[0010] Note that R1 represents a hydrogen atom, an alkali metal, an alkaline earth metal, an ammonium salt, or an alkyl or alkenyl group having from 1 to 18 carbon atoms, in which the alkali metal for R1 includes Na, K, Li, or the like, the alkaline earth metal includes Ca, Mg, Ba, or the like, and the alkyl or alkenyl group should preferably have from 1 to 10 carbon atoms. R2, R3, and R4 independently represent a hydrogen atom, a hydroxyl group, an alkoxy group having from 1 to 18 carbon atoms, preferably from 1 to 10 carbon atoms, a polyoxyethylene group, a polyoxypropylene group, or a monosaccharide, disaccharide, or oligosaccharide residue. The polyoxyethylene group is preferably of the formula, —(OC2H4)mH wherein m=1 to 100, preferably 2 to 40, and the polyoxypropylene group is preferably of the formula, —(OC3H6)nH wherein n=1 to 100, preferably 2 to 40. Specific examples of the monosaccharide, disaccharide or oligosaccharide residue include those residues of saccharides such as glucose, fructose, galactose, mannose, xylose, sucrose, lactose, stachyose, raffinose, fructooligosaccharide, galactooligosaccharide, lactosucrose, isomaltooligosaccharide, soybean oligosaccharide, xylobiose, and the like.


[0011] In the practice of the invention, one or more compounds (component A) of the formula (I) wherein two of R2, R3, and R4 independently represent a monosaccharide, disaccharide, or oligosaccharide residue should be present in an mount of 90% or over, preferably 95% or over, and one or more compounds (component B) of the formula (I) wherein one of R2, R3, and R4 represents a monosaccharide, disaccharide, or oligosaccharide residue should be present in an amount of from 0.001% to less than 10%, preferably from 0.01% to 5% each based on the total content of the gallic acid derivatives of formula (1). When the component B is formulated in an amount of 0.001% or over, one is enabled to suppress the component A from being settled at low temperatures, and satisfactory results are not obtained when using the component B in smaller amounts. The component B is poorer in high temperature stability in the course of preparation than the component A, so that if it is formulated in amounts of 10% or over, the resultant preparation may undergo a color change at high temperatures.


[0012] For example, the component A includes: gallic acid-3, 5-diglucoside; gallic acid-3, 4-diglucoside; methyl gallate-3,5-diglucoside; ethyl gallate-3,5-diglucoside; propyl gallate-3,5-diglucoside; butyl gallate-3,5-diglucoside; gallic acid-3,5-dimannoside; sodium gallate-3,5-diglucoside; ammonium gallate-3,5-diglucoside. Preferably, gallic acid-3,5-glucoside is used.


[0013] On the other hand, the component B includes, for example, gallic acid-3-glucoside, methyl galate-3-glucoside, ethyl galate-3-glucoside, propyl galate-3-glucoside, gallic acid-4-glucoside, sodium gallic acid-3-glucoside, ammonium gallic acid-4-glucoside, gallic acid-3-mannoside, gallic acid-4-mannoside, methyl galate-4-mannoside and the like.


[0014] It will be noted that gallic acid derivatives of the formula (I) other than the components (A) and (B) may be contained in amounts of not larger than 5%, preferably not larger than 1% based on the total content of the gallic acid derivatives of formula (1).


[0015] So far as the gallic acid derivatives used in the invention consist of those compounds defined hereinabove, they may be ones that are extracted from plants or are obtained by synthesis, and may be ones that are either anhydrous or hydrous. Although the preparation of the gallic acid derivatives is not critical, the derivatives can be readily and efficiently prepared, for example, by reacting gallic acid or its ester with a saccharide whose hydroxyl groups are partially or fully acetylated or a saccharide halogenated at the anomer position thereof in a solvent in the presence of an acid catalyst such as, for example BF3/Et2O, SnCl4, ZnCl2, or the like to obtain a glucosylated product, followed by protective-group elimination reaction in the presence of an acid or an alkali, if necessary, and purification by extraction or column chromatography.


[0016] The total content of the gallic acid derivatives is not critical in the practice of the invention. When the preparation for external use is applied to as a hair cosmetic, the derivatives can be formulated at a concentration of 0.01 to 20%, preferably from 0.1 to 10%, based on the total amount of the external preparation. If the total content is smaller than 0.01%, the effect of the gallic acid derivatives may not be obtained satisfactorily. On the other hand, when the total content exceeds 20%, a further increasing effect is not expected, with the possibility of poor economy.


[0017] The external preparation according to the invention should preferably contain a cationic surface active agent. Examples of the cationic surface active agent include those indicated below.


[0018] (1) Amine Salts and Ammonium Salts
4


[0019] wherein R5, R6, R7, and R8 independently represent a hydrogen atom, an alkyl group, a hydroxyalkyl group, an alkenyl group, an polyalkylene oxide, or a benzyl group provided that one or two of R5, R6, R7, and R8 independently represent a linear or branched alkyl group, hydroxyalkyl group, or alkenyl group having from 8 to 24 carbon atoms, and the others may be the same or different and independently represent a hydrogen atom, a methyl group, an ethyl group, a benzyl group, or an polyalkylene oxide group, which is represented by —(C2H4O)qH or —(C3H6O)rH wherein q and r are an integer of 1 to 5 respectively; X represents an anion derived from an inorganic or organic acid such as a chloride, a bromide, a iodide, a sulfate, a methylsulfate, an ethylsulfate, an acetate, a pyrrolidonecarboxylate, a glycolate, a citrate, a succinate, a p-toluenesulfonate, a pyroglutaminate, a high fatty acid salt, an acidic amino acid salt, or the like.

[0021] wherein R9 represents a linear or branched alkyl group or alkenyl group having from 1 to 21 carbon atoms; A represents a linear or branched alkylene group or alkenylene group having from 1 to 10 carbon atoms; t is an integer of 1 to 5 provided that if t is 2 or over, A in the respective moieties may be the same or different; X has the same meaning as defined in the formula (II).


[0022] (3) Benzethonium Salts
6


[0023] wherein R9 has the same meaning as defined above; R10 and R11 may be the same or different and independently represent a hydrogen atom, a methyl group, an ethyl group, a benzyl group, or an polyalkylene oxide group, which is represented by, —(C2H4O)qH or —(C3H6O)rH wherein q and r are an integer of 1 to 5 respectively; X has the same meaning as defined above.


[0024] (4) Pyridinium Salts
7


[0025] wherein R9 and X respectively have the same meanings as defined above.


[0026] (5) Pyrrolidonecarboxylates
8


[0027] wherein R9, R10, R11, and X respectively have the same meanings as defined above.


[0028] Mention is also made of other types of amino acid-based cationic surface active agents such as lower alkyl esters of mono-N-long chain acyl group-bearing basic amino acids. The basic amino acids of the compounds include, for example, natural amino acids such as ornithine, lysine, arginine, and the like. Alternatively, synthetic amino acids such as α,γ-diaminobutyric acid may also be used. These may be either an optical active substance or a racemic substance. The acyl group includes a saturated or unsaturated higher fatty acid residue having from 8 to 22 carbon atoms. These may be either of a natural origin or of a synthetic type. For instance, single higher fatty acid residues such as a lauroyl group, a myristoyl group, a palmitoyl group, a stearoyl group, and the like may be adapted. In addition, natural mixed higher fatty acid residues such as coconut oil fatty acid residues and tallow high fatty acid residues may be adopted. The lower alkyl ester components preferably include a methyl ester, an ethyl ester, a propyl ester, a butyl ester, a pentyl ester, a hexyl ester, a heptyl ester, and an octyl ester. The counter ion includes ones as defined with respect to X in the foregoing formulas.


[0029] Specific examples of the cationic surface active agent include stearyltrimethylammonium chloride, cetyltrimethylammonium chloride, behenyltrimethylammonium chloride, distearyldimethylammonium chloride, dioleyldimethylammonium chloride, didecyldimethylammonium chloride, lauric acid amide butylguanidine acetate, myristic acid amide butylguanidine acetate, palmitic acid amide butylguanidine acetate, distearyldimethylammonium sulfate, stearylethyldihydroxyethylammonium sulfate, N-coconut oil fatty acid L-arginine ethyl/DL-pyrrolidone carboxylate, and the like. These may be used singly or in combination of two or more. Of these, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, and lauric acid amide butylguanidine acetate are preferred.


[0030] In the external preparation of the invention, the content of the cationic surface active agent can be appropriately controlled depending on the purpose in end use of the preparation and is not critical. Where the external preparation is employed as a hair cosmetic, the content ranges from 0.01 to 20%, preferably from 0.1 to 15% and more preferably from 0.1 to 10% based on the total amount of the external preparation. If the content is smaller than 0.01%, the low temperature stabilizing effect of a cationic surface active agent cannot be obtained satisfactorily. In contrast, when the content exceeds 20%, a further effect may not be expected, which may result in poor economy.


[0031] Water used in the invention is not critical in type, and city water, ion-exchanged water, distilled water, natural water, or the like may be used. A polar organic solvent is also not critical, and those ordinarily employed for preparations for external use are used, of which ethanol or isopropanol is preferred.


[0032] The preparation for external use according to the invention should be preferably formulated further with a silicone compound so as to improve the usability upon application to hair. Examples of the silicon compound include dimethylpolysiloxanes (including highly polymerized dimethylpolysiloxane and silicone rubbers), methylphenylpolysiloxane, polyether-modified silicones, amino-modified silicones, betaine-modified silicones, alcohol-modified silicone, fluorine-modified silicones, epoxy-modified silicones, mercapto-modified silicones, carboxy-modified silicones, fatty acid-modified silicones, silicone-grafted polymers, cyclic silicones, alkyl-modified silicones, trimethylsilyl-terminated dimethylpolysiloxane, silanol group-terminated dimethylpolysiloxane, crosslinking alkyl polyether-modified silicones, and the like. Of these, polyether-modified silicones and amino-modified silicones are preferably used. These silicone compounds may be used as an emulsion by preparation with use of a surface active agent.


[0033] Although the viscosity of the silicones (except for the emulsion type) is not critical, the viscosity at 25° C. is preferably in the range of 10 to 1,000,000 mm2/s, more preferably 30 to 100,000 mm2/s, when taking the usability as a hair cosmetic into account.


[0034] In this connection, the amount of a silicone compound is appropriately selected and is usually in the range of 0.01 to 20%, preferably from 0.1 to 10%, based on the total of the preparation for external use.


[0035] Moreover, for the purpose of imparting stiffness and elasticity to hair, it is preferred to formulate 0.0001 to 1% of gallic acid and/or 0.0001 to 5% of sodium sulfate. Gallic acid may be one extracted from a natural product or obtained by synthesis, or may be anhydrous or hydrous. Sodium sulfate may be either anhydrous or hydrous.


[0036] Where an external preparation including a gallic acid glucoside, a cationic surface active agent, and a silicone compound as set forth hereinabove is applied as a hair cosmetic, a raspiness of hair, particularly a raspiness of hair damaged by chemical treatments such as of a permanent or hair coloring, daily exposure to UV light, or by blowing with a dryer, can be improved.


[0037] Hitherto, improvements in raspiness of hair have been frequently limited to the raspiness in a wet condition experienced mainly after shampooing. Most of the improvements are made by formulating cationized compounds in shampoos or the like (Japanese Patent Laid-open Nos. Hei 04-273811, Hei 06-40864, Hei 06-345620, Hei 08-143432, etc.) and by formulating silicones (Japanese Patent Laid-open Nos. Hei 06-32724, Hei 07-285836, Hei 07-316024, Hei 08-310922, Hei 09-124437, etc.), and limiting the types of activator species for detergents (Japanese Patent Laid-open Nos. Hei 05-124921, Hei 05-125392, Hei 06-40864, Hei 07-258044, Hei 08-12993, Hei 08-143432, Hei 09-157140, etc.). However, limitation is placed on their use in bath in most cases, with the effect thereof being not satisfactory.


[0038] The present inventors found that a raspiness of hair can be remarkably improved by that combination of such gallic acid glucoside, cationic surface active agent, and silicon compound set out hereinabove are applied to hair.


[0039] When such a gallic acid glucoside is formulated with ethyl alcohol, a hair cosmetic is obtained. In this case, 0.01 to 10 %, preferably 0.1 to 5%, and more preferably 0.1 to 2% of a gallic acid glucoside and 5 to 90%, preferably 10 to 60%, and more preferably 10 to 30% of ethyl alcohol are combined, if necessary, together with 0.01 to 10%, preferably 0.1 to 5%, and more preferably 0.1 to 3% of a surface active agent and/or 0.01 to 30%, preferably 0.1 to 10%, and more preferably 0.1 to 5% of a high molecular weight compound, thereby providing a hair cosmetic. When this cosmetic is applied to hair, the gallic acid glucoside is allowed to be fully infiltrated inside the hair, thereby obtaining a high color degradation preventing effect. When using the hair cosmetic, dyed hair can be prevented from color degradation and dulling with time. Therefore, the cosmetic is able to keep the hair color that is immediately after dyeing.


[0040] The preparation for external use according to the invention may further includes, aside from the essential components, various types of components ordinarily employed in cosmetics, quasi drugs, medicines, and the like within ranges of amounts not impeding the effect of the invention, if necessary. Such components include, for example, anionic surface active agents such as sodium α-olefinsulfonates, potassium α-olefinsulfonates, sodium stearate, sodium palmitate, sodium laurate, sodium coconut oil fatty acid salt, arginine stearate, arginine palmitate, arginine laurate, coconut oil fatty acid salt of arginine, sodium laurylsulfate, sodium polyoxyethylene alkyl ether sulfates, ammonium polyoxyethylene alkyl ether sulfates, sodium polyoxyethylene alkyl ether phosphates, sodium polyoxyethylene polyoxypropylene alkyl ether phosphates, sodium lauroyl sarcosine, sodium coconut oil fatty acid salt of methyl-β-alanine, sodium dioctylsulfosuccinate, disodium polyoxyethylene alkylsulfosuccinate, sodium polystyrenesulfonate, disodium sulfosuccinate, sodium N-lauroyl-N-methyl-β-alanine, sodium malic acid monolaurylamide, and the like; amphoteric surface active agents such as 2-alkyl-N-carboxyethyl-N-hydroxyethylimidazolinium betaine, coconut oil fatty acid amidopropyl betaine, lauric acid amidopropyl betaine, lauryldimethylaminoacetic acid betaine, hydrogenated soybean phospholipid, alkyldiaminoethylglycine hydrochloride, N-[3-alkyloxy-2-hydroxypropyl]-L-arginine hydrochloride, sodium laurylaminopropionate, and the like; nonionic surface active agents such as sugar fatty acid esters, sorbitan fatty acid esters, sorbitol fatty acid esters, polyglycerine fatty acid esters, glycerine fatty acid esters, polyoxyethylene alkyl ethers, polyoxyethylene phytosterol ether, polyoxyethylene polyoxypropylene alkyl ethers, polyoxyethylene polyoxypropylene phytosterol ethers, hydrogenated castor oil, hydrogenated castor oil fatty acid esters, polyoxyethylene hydrogenated castor oil, polyoxyethylene polyoxypropylene hydrogenated castor oil, polyoxyethylene hydrogenated castor oil fatty acid esters, polyoxyethylene polyoxypropylene hydrogenated castor oil fatty acids, and the like; oils such as isopropyl myristate, isopropyl palmitate, ethyl oleate, octyldodecyl neopentanoate, butyloctyl salicylate, cholesteryl stearate, polyoxyethylene, liquid paraffin, liquid isoparaffin, squalene, squalane, castor oil, jojoba oil, hazelnut oil, sweet almond oil, grape seed oil, sasanqua oil, safflower oil, olive oil, meadow home oil, rose hip oil, avocado oil, and like; polymers such as hydromethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, cationized cellulose, polyvinyl pyrrolidone, polyvinyl alcohol, acrylic acid/methacrylic acid copolymer, carboxyvinyl polymer, and the like; amino acid such as glycine, ornithine, methionine, alanine, arginine, glutamine, cysteine, cysteic acid, cystine, leucine, isoleucine, aspartic acid, lysine, phenyl alanine, and the like; plant extracts such as of rosemary, capsicum, rumex japonicus, aloe, lycium chinese, mugwort, mustard, rice plant, licorice, Cape jasmine, white birch, sophorae radix, sponge cucumber, eucalyptus, arnica, and the like; extracts of algae such as kelp, chlorella, ascophyllum nodosum, coralline algae, eucheuma, and the like; polyhydric alcohols such as propylene glycol, dipropylene glycol, glycerine, butylene glycol, and the like; preservatives such as paraoxybenzoates, paraoxybenzoic esters, and the like; sequestering agents such as edetates, pyrophosphates, citrates, glycolates, tartaric acid, and the like; gases such as liquefied petroleum gas, dimethyl ether, nitrogen, carbon dioxide gas, and the like; antioxidants such as dibutylhydroxytoluene, butylhydroxyanisole, erythorbic acid, dilauryl thiopropionate, sodium sulfate, sodium sulfite, tocopherol, ascorbyl dipalmitate, and the like; UV absorbers such as p-aminobenzoic acid derivatives, salicylic acid derivatives, cinnamic acid derivatives, oxybenzone, dioxybenzone, dihydroxydimethoxybenzophenone, and the like; pH adjusting agents such as succinic acid, citric acid, tartaric acid, lactic acid, glycolic acid, and the like; vitamins, dyes, refrigerant such as 1-menthol and derivative of thereof, humectants, thickeners, and the like.


[0041] The perfume composition may be formulated in the preparation for external use of the invention. In this case, the perfume composition is preferably formulated in an amount of 0.00001 to 10%, more preferably 0.0001 to 5%, based on the total of the external composition.


[0042] The form of the external preparation is not critical and the preparation may be used, for example, in various forms of a solution, an emulsion, a dispersion, an oil-water double-layered system and can be used in the forms of an aerosol, a tick, a gel, a cream, a lotion, and the like.
