Description
TECHNICAL FIELD

The present invention relates to a functional composition for surface modification of hair, skin, hide, or a fabric.


BACKGROUND ART

In general, hair, dead skin cells, fingernails, toenails, and wool fabrics mainly consist of keratin proteins, and anhydrous hair fibers are composed of about 90 to 97% proteins and about 2% lipids, and the remainder consists of nucleic acids, carbohydrates, and inorganic materials.


Hair is composed of about 50 wt % carbon, 7 wt % hydrogen, 22 wt % oxygen, 16 wt % nitrogen, and 5 wt % sulfur, as determined through an elemental analysis. As such, the major difference between the keratin proteins constituting hair and other common proteins is that a specifically large amount of the element sulfur is contained in amino acids constituting the protein. The specifically large amount of sulfur present in the keratin proteins of hair is known to play a very important role in maintaining the strength of hair protein by forming disulfide bonds (cysteine bonds) in hair.


The disulfide bonds present in hair are broken into cysteine through reduction accomplished by chemical treatment of hair, external environmental factors such as UV, or the like, and it is known that keratin of hair contains cysteine in an amount of about 16.6 to 18% of the total amino acids, whereas keratin of the epidermis contains cysteine only in an amount of about 2.3 to 3.8%, and collagen proteins of skin do not contain cysteine.


As such, the keratin proteins of hair have a significant difference from common proteins in terms of the content of cysteine. Wool fabrics made of wool are widely known to have a structure and composition of protein similar to those of human hair, and thus can be considered to contain a large amount of cysteine at a level similar to that in the proteins of hair.


In general, cosmetics, which are applied or spread on the human body, or used by other similar methods to cleanse and beautify the human body, promote attractiveness, change an appearance, or keep skin or hair healthy, mildly act on the human body.


Such cosmetics have various functions of washing, softening, imparting elasticity, volumizing, repairing damage, strengthening, dyeing, protecting, conditioning, bonding, blocking ultraviolet rays, suppressing and removing odors, antioxidizing, moisturizing, removing and alleviating blemishes, applying fragrances, removing and preventing dandruff and itching, perming, whitening, preventing wrinkles, stimulating and suppressing body hair growth, fingernail and toenail care, and oral cavity care, and also have functions of keeping various parts of the human body healthy and beautiful.


Examples of raw materials commonly used to constitute such cosmetics include oil-soluble raw materials such as oils and fats, waxes, hydrocarbons, higher fatty acids, higher alcohols, ester oils, silicone oils, and the like, polymer compounds used as anionic, cationic, amphoteric, or nonionic surfactants, whiteners, thickeners, or film formers, ultraviolet ray absorbents, ultraviolet ray blockers, antioxidants, chelating agents, coloring materials such as dyes or pigments, fragrances, preservatives, and the like.


In addition, examples of components for providing a specific functionality include oils and fats, natural or synthetic fatty acids, fatty alcohols, alcohols, alkyl glyceryl ethers, esters, hydrocarbons, silicones, fluorine compounds, polyhydric alcohols, sugars, natural or synthetic polymers, waxes, vitamins, hormones, amino acids, peptides, proteins, animal, plant, and mineral extracts, and derivatives thereof.


However, when hair, dead skin cells, fingernails, toenails, and wool fabrics are treated with such cosmetic components, it only provides a temporary and short-term effect until the next wash after the treatment, and the cosmetic component is completely washed away by the washing process so that the effect of the cosmetic component disappears. Therefore, there is always the inconvenience of re-treating hair, dead skin cells, fingernails, toenails, and wool fabrics with the cosmetic component.


In Korean Unexamined Patent Publication No. 2008-0064467, there is disclosed a non-aqueous personal care product for skin or hair. The personal care product for skin or hair includes a hair surface-modifying component and consists of a non-aqueous part and an aqueous part, wherein the non-aqueous part includes one or more selected from the group consisting of functional groups capable of covalently bonding with a protein residue in a hair or skin surface, such as carbonates, aldehydes, propionaldehyde, butylaldehyde, nitrophenyl carbonate, aziridines, isocyanate, thiocyanate, epoxides, tresylates, succinimide, hydroxysuccinimidyl esters, imidazole, oxycarbonylamidazole, imines, thiols, vinylsulfone, ethyleneimine, thioethers, acrylonitrile, acrylic or methacrylic acid ester, disulfides, ketones, and functional groups represented as RX (here, R is any one selected from the group consisting of alkyls, aryls, aralkyls, rings, and unsaturated rings, and X is I, Br, or Cl), and the non-aqueous part and the aqueous part are mixed immediately before using the product. However, various functional groups as described above are harmful to humans, or target, among amino acids of proteins constituting hair or skin, lysine contained in a small amount in hair and skin keratin (1.9 to 3.1% in hair and 3.1 to 6.9% in skin keratin) or cysteine contained in a small amount in hair and skin keratin (16.6 to 18% in hair and 2.3 to 3.8% in skin keratin) to participate in a reaction. Therefore, reaction efficiency is degraded, and each material needs to be synthesized separately.

The functional component having a functional group capable of covalently bonding with a thiol (—SH) group of cysteine in a molecule may be used in an amount of 0.0001 to 50 parts by weight, 0.001 to 30 parts by weight, 0.01 to 10 parts by weight, or 0.1 to 5 parts by weight with respect to 100 parts by weight of the entire composition. When the content of the functional component is less than 0.0001 part by weight, there is a limitation in providing the effect of an active component, and when the content of the functional component is greater than 50 parts by weight, there is a problem in formulation and the stability of formulation over time, and the component may be lost without reacting.


In order to increase the effect of the functional component, the functional composition according to the present invention may also include a cystine reducing agent in addition to the functional component having a functional group capable of covalently bonding with a thiol (—SH) group of cysteine in a molecule, so that the content of cysteine in hair, skin, fingernails, toenails, a hide, and/or a fabric, which is capable of reacting with an alkene, a vinyl group, or an alkyne, may increase.


Therefore, the present invention provides the functional composition for surface modification including the functional component having a functional group capable of covalently bonding with a thiol (—SH) group of cysteine in a molecule and the cystine reducing agent.


The cystine reducing agent serves to break a disulfide bond (—S—S—) into cysteine (—SH) through reduction, and may be, specifically, one or more selected from the group consisting of ascorbic acid, erythorbic acid, sodium ascorbate, potassium ascorbate, calcium ascorbate, ammonium ascorbate, monoethanolamine ascorbate, diethanolamine ascorbate, sodium erythorbate, disodium ascorbyl sulfate, disodium erythorbyl sulfate, magnesium ascorbyl phosphate, ascorbyl palmitate, ascorbyl stearate, ascorbyl dipalmitate, ascorbyl tetra 2-hexyl decanoate, ascorbyl myristate, ascorbyl laurate, ascorbyl acetate, ascorbyl propionate, ascorbyl tartrate, ascorbyl citrate, ascorbyl succinate, ascorbyl benzoate, potassium (ascorbyl/tocopheryl) phosphate, ethyl ascorbic acid, allantoin ascorbate, chitosan ascorbate, methylsilanol ascorbate, ascorbyl tetradecyl hexyl, aminopropyl ascorbyl phosphate, ascorbic acid polypeptide, ascorbyl glucoside, ascorbyl methylsilanol pectinate, thioglycolic acid, thioglycolate, thioglycolic acid ester, ammonium thioglycolate, sodium thioglycolate, glyceryl thioglycolate, cysteine, cysteine hydrochloride, N-acetyl-L-cysteine, thioglycerol, thiolacetic acid, thiomalic acid, cysteamine, sulfurous acid, ammonium sulfite, sodium sulfite, ammonium hydrogensulfite, sodium hydrogensulfite, thiosulfuric acid, sodium thiosulfate, cystamine, N,N′-bisacryloyl-cystamine, 3,3′-dithiopropionic acid, glutathione disulfide, cysteine hydrochloride, N-acryloyl-cysteamine, 2-iminothiolane, N-acetylhomocysteine thiolactone, 1,4-dithiothreitol, glutathione, and salts and derivatives thereof, but the present invention is not limited thereto.

The cystine reducing agent may be used in an amount of 0.0001 to 20 parts by weight, 0.001 to 10 parts by weight, 0.01 to 5 parts by weight, or 0.1 to 3 parts by weight with respect to 100 parts by weight of the entire composition. When the content of the cystine reducing agent is less than 0.0001 part by weight, there may be a problem in actual reduction of cystine due to an excessively low content, and when the content of the cystine reducing agent is greater than 20 parts by weight, a substrate to be treated may be damaged, the stability of a formulation may be degraded, and the contents may have bad odor due to excessive reduction.


The Reaction Scheme 1 in FIG. 1 shows a schematic diagram of a reaction according to one embodiment of the present invention, in which [2-(acryloyloxy)ethyl] trimethyl ammonium chloride, which is an antimicrobial functional component having a vinyl group as a functional group reactive with cysteine in a molecule, and cysteine hydrochloride, which is a reducing agent, react with hair to reduce cystine, and thus covalent bonds between cysteine in hair and the cosmetic component are formed.


Reaction Scheme 1 in FIG. 1 illustrates a method in which a reducing agent is applied first to reduce a disulfide bond, and a reducing agent and a functional component are applied together at the same time, which is used to form covalent bonds.


The cysteine-reactive functional component bonded to hair, skin, fingernails, toenails, a hide, and/or a fabric may not be easily detached during general washing with a shampoo, a detergent, a soap, or the like, but may be almost permanently attached to the hair, skin, fingernails, toenails, a hide, and/or fabric.


In order to additionally increase an effect of the composition for surface modification according to the present invention, the composition may be used in combination with a fatty acid (palmitic acid, stearic acid, and the like), a fatty alcohol, a cationized polymer such as a cationic surfactant (linear/branched long-chain alkyl quaternary ammonium salts or the like), cationic cellulose, cationic guar, cationic polyvinylpyrrolidone, and the like, a silicone, or the like for ease of formulation.

The components for formulation may be used in an amount of 40 to 99 parts by weight with respect to 100 parts by weight of the entire composition.


The composition for surface modification according to the present invention may be used in the treatment with a care product for hair, skin, fingernail, toenail, hide, or fabric surface modification.


For hair, any one of cosmetic formulations that can be used for hair, such as pre-shampoo products, shampoos, conditioners, hair treatments, waxes, sprays, mousses, hair lotions, essences, hair creams, packs, masks, sheets, tablets, patches, strips, ointment-type products, permanent dyes, temporary dyes, hair perm products, and the like, may be used. For skin, any one of cosmetic formulations that can be used for skin, such as body and facial cleansers, softeners, toners, lotions, essences, serums, creams, gels, foundations, powders, makeup bases, point makeup products, masks, patches, and the like, may be used. For fingernails and toenails, any one of fingernail and toenail care formulations that can be used for fingernails and toenails, such as nail varnishes, coats, nail polishes, coloring agents, nail hardeners, therapeutic agents, nail softeners, and the like, may be used. For a hide, any one of hide care formulations that can be used for a hide, such as coats, cleaners, softeners, polishes, and the like, may be used. For a fabric, any one of fabric care formulations that can be used for a fabric, such as fabric softeners, fabric dyes, laundry detergents, fabric treatments, pre- and post-treating agents, laundry aids, and the like, may be used.


More preferably, the composition for surface modification according to the present invention includes a functional component. If the activity of the formulation is degraded when the formulation is in an aqueous environment, it may be beneficial if the formulation takes a non-aqueous form to maintain its activity, which may be achieved by inducing a reaction of the formulation by mixing it with a buffer solution immediately before use to adjust a pH or bringing it in contact with water in a washing process. Examples of a non-aqueous form include liquid-phase solubilized products, liquid-phase emulsions, liquid-phase dispersed products, packs, masks, sheets, tablets, patches, strips, ointment-type products, formulations containing capsules, powder-type products, tablet-type products, oils, waxes, ampoules, gels, and the like, which are commonly used as non-aqueous cosmetic formulations. In order to increase the effect of the functional component in the composition for surface modification according to the present invention, a dibasic acid ester such as dioctyl succinate, dioctyl adipate, diethyl sebacate, or the like, a polyol, polyethylene glycol, propylene glycol, hexylene glycol, butanediol and an isomer thereof, glycerol, benzyl alcohol, or ethoxydiglycol and a derivative thereof may be used. The solvent mentioned above serves to increase permeability into the hair and skin and is used as a solvent for a poorly soluble material.


As described above, a component for surface modification having two or more reactive functional groups reacts with a hair, skin, fingernail, toenail, hide, or fabric surface to form a surface-modifying layer with a multi-layer structure, which may result in increasing reaction efficiency. Also, a functional component having a functional group capable of covalently bonding with the protein in a hair, skin, fingernail, toenail, hide, or fabric surface may be additionally used and reacted with the outermost surface of the surface-modifying layer to provide an additional effect besides a surface modification effect.
