HYDROGEL HAIR COSMETIC COMPOSITION AND PREPARATION METHOD OF THE SAME [0002]

The present invention relates to a hydrogel hair cosmetic composition. More particularly, the present invention relates to a hydrogel hair cosmetic composition which has excellent strength and elasticity, has a rich amount of foam when used, has a soft foam texture, exhibits excellent washing power, rinsing power and moisturizing power, and a method for producing the same.

A hydrogel is a polymeric material that forms a three-dimensional network by cross-linking a chain of hydrophilic polymers. It is water-insoluble and does not dissolve in water. Hydrogels have strong hydrophilic polar groups, which form covalent bonds, ionic bonds, hydrogen bonds or van der Waals bonds to form a three-dimensional network. The hydrogel is divided into a chemical crosslinking gel and a physical crosslinking gel according to the production method.

Chemically crosslinked gels or permanent gels have a crosslinked structure formed by a strong covalent bond, which has an excellent mechanical stability due to bonding, and is free from structural changes even to external stimuli. However, after crosslinking There is a disadvantage in that a process for removing residual toxic initiators and crosslinking agents is required.

Physically crosslinked gels or reversible gels have a crosslinked structure formed by hydrogen bonding, ionic bonding or electrostatic attraction and are sensitive to external stimuli (pH, temperature, electric field, light, etc.) Reaction and change, and various applications are possible by using these characteristics. In addition, since it can be produced without using an initiator or a crosslinking agent which is harmful to human body or can affect the active ingredient contained in the gel, interest in physical crosslinking gel is increasing.

The hydrogel can be manufactured by selecting a polymer having excellent biocompatibility and a non-harmful crosslinking method. It can contain various active ingredients in the gel, and can be used as a wound dressing, a contact lens, an artificial cartilage or a DDS (drug delivery system) and TDS (transdermal delivery system) as a cosmetic material.

In the case of human body cleansing agents using hydrogels, it is necessary to include harmless ingredients and manufacturing process, and to have excellent elasticity and strength for continuous use, and to have excellent washing power and rinsing power for achieving the object.

U.S. Patent No. 6,090,7663 discloses a human body washing soap using poly (vinyl alcohol). Polyvinyl alcohol is a synthetic polymer and has hydrophilicity. At room temperature, the aqueous solution is liquid. However, when freezing-thawing is performed, crystallization occurs between the polymer chains in the aqueous solution, do. However, since the hydrated gel human cleansing soap requires a freezing process at 0 ° C or lower during production, there is a restriction in the production facility and the strength necessary for the human body cleansing agent can not be obtained in a single freeze- There is a problem in that time and cost are wasted due to the freezing-thawing process.

Korean Patent Publication No. 2004-53807 discloses a human body cleaning soap using gelatin. Herein, gel-like human cleansing soap was prepared by mixing a gel-type animal protein gelatin with a surfactant. The human soap prepared in this way is difficult to handle because it is sticky because of its adhesive property which is a gelatin property, and it is not only hard to handle but also it is not excellent in strength and elasticity, so that it is broken or scratched when used. In addition, the amount of foam is so small that the detergency is low, the rinsing property is also low, and it is difficult to have a dense and smooth foam texture.

The present invention is to provide a hydrated gel hair cosmetic composition which has excellent strength and elasticity, has a rich amount of foam during use and a soft foam texture, exhibits excellent washing power, rinsing power and moisturizing power, and a method for producing the same.

The present invention provides a hair styling cosmetic composition comprising 25 to 60% by weight of a poly saccharide-based gel broth, 5 to 50% by weight of a surfactant, and 5 to 65% by weight of water.

The present invention also provides a method for producing a hydrated hair cosmetic composition comprising adding water to a surfactant and a polysaccharide gel-type broth and dissolving the mixture by warming and cooling the aqueous solution dissolved by heating.

Hereinafter, the hydrogel hair cosmetic composition according to the embodiment of the present invention and its preparation method will be described in more detail.

According to one embodiment of the invention, there is provided a hydrogel hair cosmetic composition comprising 25 to 60% by weight of a poly saccharide-based gel broth, 5 to 50% by weight of a surfactant, and 5 to 65% by weight of water do.

The hydrogel hair cosmetic composition according to one embodiment of the present invention includes a polysaccharide compound as a gel broth capable of crosslinking by hydrogen bonding, ionic bonding, electrostatic attraction or the like to form a physical crosslinking gel. As a result of experiments conducted by the inventors of the present invention, it has been found that the cosmetic composition containing such a polysaccharide-based gel broth has improved strength and elasticity compared with conventional gelatin-based soaps and can be used continuously while maintaining its shape. Also, it has been found that when used, it has a rich amount of foam, a smooth foam texture, excellent washing power, rinsing power and moisturizing power.

The gel broth is preferably contained in an amount of 25 to 60% by weight, more preferably 30 to 40% by weight. If the content is too small, it is difficult to form a hydrogel due to the shortage of cross-linkable polymer. If the content is too large, the polymer may not hydrate sufficiently, and viscosity may be high, resulting in deterioration of processability. In addition, if the content of the gel-form broth is excessively large, there is a limit to increase the amount of the surfactant to improve the foam amount and the cleaning power.

The gel broth may be selected from the group consisting of alginate, pectin, gellan gum, carrageenan, starch, xanthan gum, agar, guar gum, , Locust bean gum, tamarind gum, and carboxymethyl cellulose (CMC).

The amount of the surfactant is preferably 5 to 50% by weight, more preferably 10 to 35% by weight. When the content is less than 5% by weight, the amount of foams is small. When the content is more than 50% by weight, crosslinking of the gel broth is prevented and it is difficult to form a hydrogel.

These surfactants can be used either singly or in combination of two or more of an anionic surfactant, a nonionic surfactant or an amphoteric surfactant. Examples of the anionic surfactant include sodium lauryl sulfate, ammonium lauryl sulfate, magnesium lauryl sulfate, triethanolamine lauryl sulfate, sodium polyoxyethylene lauryl sulfate or ammonium polyoxyethylene lauryl sulfate, and the nonionic Examples of the surfactant include water-soluble dimethylamine oxide, palm oil alkyldimethylamine oxide, lauryl acid diethanolamide, palm oil fatty acid diethanolamide, palm oil fatty acid monoethanolamide, polyoxyethylene lauryl ether or polyoxyethylene nonylphenyl ether And amphoteric surfactants such as cocamidopropyl betaine, cocoamphocarboxy glycinate or cocoamphocarboxylophosphonate may be used as the amphoteric surfactant. It is needless to say that various surfactants known to be usable for the human body cleaning composition or the cosmetic composition can be used without limitation.

Such a moisturizing agent is contained in an amount of 1 to 50% by weight. When the content of the moisturizing agent is less than 1% by weight, it is difficult to expect a moisturizing effect. When the content of the moisturizing agent is more than 50% by weight, It is not good.

The moisturizing agent may include one or more selected from the group of polyalcohol compounds consisting of glycerin, propylene glycol, 1,3-butylene glycol, polyethylene glycol, sorbitol and mannitol, and besides, various compounds usable as hair moisturizers are limited Can be included without.

The hair cosmetic composition according to one embodiment of the present invention may further contain at least one selected from the group consisting of preservatives, thickeners or viscosity adjusting agents, pH adjusting agents, perfumes, dyes, conditioning agents and stabilizers in order to maintain basic properties and quality . These respective preservatives, thickeners (or viscosity adjusting agents), pH adjusting agents and the like may be conventional materials used in hair cosmetics, respectively, and these materials are obvious to those skilled in the art.

The hardness (penetration hardness) of such a hydrogel hair cosmetic composition can be preferably 5 to 100 dyne, more preferably 5 to 50 dyne. If the hardness of the composition is too low, the hydrogel may be destroyed during use. On the contrary, if the composition is too high, the composition itself becomes hard and it is difficult to provide a scalp massage feeling.

Since the hydrogel hair cosmetic composition according to one embodiment of the present invention uses a polysaccharide gel-type gel broth, it has sufficient strength to maintain its shape as compared with a gel made of gelatin, but fatty acid-based soap -based soap or a surfactant-based soap. Accordingly, such a hydrogel hair cosmetic composition has a low hardness value so as to be soft, but it has sufficient elasticity and is sufficient to provide an excellent massage feeling to the user.
