The present invention relates to a skin cleanser composition, more preferably a skin cleanser composition containing mannitol, the skin cleanser composition according to the present invention has an excellent effect of promoting rapid solubility in water, stability in high humidity conditions and moisturizing of the skin Because it has a, it can be usefully used as a cleaning agent, preferably a film type cleaning agent.

Paper soap has been used as a portable or disposable product due to its convenience, but has a disadvantage in that it is easily broken and not aesthetically advanced. In order to solve this problem, the prior art described about a thin film soap having a bubble prepared with a water-soluble polymer, that is, a polyvinyl alcohol and a cellulose-based polymer and bubbles attached with a cellulose film. 1998-052351) and prior art (US Patent Publication No. US2005 / 0003991A1), etc., which describe a film-type soap or detergent that is rapidly dissolved in water by adding a surfactant and a plasticizer to a water-soluble polymer. These products are flexible so that they can not be easily broken even when wrinkled, and logos or patterns can be added to the film as needed, which is not only aesthetically luxurious but also easy to carry and disposable. However, the relative characteristics of the water-soluble polymer, that is, the relatively poor hygroscopic property, so that the solubility in water or the relatively high hygroscopic property is high, the films stick to each other and soften in high humidity conditions to maintain the original film shape There is a problem that can not be broken. In addition, in order to solve this problem, European Patent WO02 / 095412 describes a detergent made of an outer layer material of a water-insoluble or water-dispersible sheet material (for example, a nonwoven fabric) and a water-soluble film (for example, polyethylene oxide). Although described with respect to pouches, these products have the disadvantage of having to recover from the laundry the outer layer material which is not sticky under high humidity conditions and is stable but not dissolved after use.

The technical problem of the present invention for overcoming these disadvantages is a skin cleaner composition containing mannitol, which has fast solubility in water, stability under high humidity conditions, rich foam formation, and low irritation to skin and excellent moisture retention. To provide.

Another technical problem of the present invention is to provide a skin cleanser, preferably a film type skin cleanser, containing the composition as an active ingredient.

In order to achieve the above technical problem, the present inventors completed the present invention by providing a skin cleanser composition containing mannitol, a water-soluble polymer, and a surfactant as an active ingredient.

In order to solve the above problems, the present invention provides a skin cleanser composition containing mannitol, a water-soluble polymer, and a surfactant. The content of the composition may be 0.1 to 50 parts by weight, preferably 0.5 to 30 parts by weight, and 0.1 to 70 parts by weight, preferably 0.5 to 50 parts by weight, based on 100 parts by weight of the total skin cleanser composition. It may be part, and the surfactant may be 1 to 70 parts by weight, preferably 1 to 50 parts by weight.

In addition, the composition may further include one or more plasticizers selected from polyhydric alcohols including glycerin, propylene glycol, and polyethylene glycol, depending on the purpose of use, ethylene diamine tetraacetate (EDTA), humectant, conditioning agent, preservative And additives including transparent agents (sugar, alcohol) and colorants.

In order to solve the above another problem, the present invention is characterized in that the skin cleanser containing the composition as an active ingredient, preferably a high solubility in water, stable in high humidity conditions, to promote skin moisturization without skin irritation It provides a film-type skin cleanser having.

Hereinafter, the present invention will be described in detail.

Mannitol (Mannitol) is a kind of sugar alcohol, which is contained in various mushrooms including Cordyceps and Matsutake mushrooms, and can be obtained in crystalline state in the extract of manna tree as a major component of seaweeds, especially brown algae and manna. The structural formula is similar to D-sorbitol and has a low hygroscopicity of as low as 10% even at 100% relative humidity. However, there have been no examples of using mannitol having such characteristics as a skin cleanser composition. Therefore, in the present invention, a skin cleanser composition containing mannitol, a water-soluble polymer and a surfactant was prepared. The content of mannitol added to the composition may be 0.1 to 50 parts by weight, preferably 0.5 to 30 parts by weight, based on 100 parts by weight of the total skin cleanser composition. This is because when the mannitol content is 0.5 parts by weight or less with respect to 100 parts by weight of the total composition, it is not stable under humid conditions, and when it is 30 parts by weight or more, it is difficult to form a film.

The water-soluble polymer is a material widely used in preparing a water-soluble film, and has been used as a component of the composition of the present invention because it has a characteristic of being readily dissolved when contacted with water. The water-soluble polymer that can be used is not particularly limited, and may be polyvinyl alcohol (PVA), polyvinyrrolidone, sodium alginate, starch and starch derivatives, gelatin, polyethylene oxide, methyl cellulose, hydroxypropylmethyl It may be one or more selected from the group consisting of cellulose, carboxymethyl cellulose, hydroxymethyl cellulose, hydroxypropyl cellulose, pullulan (pulluran) and xanthan gum. In addition, the content of the water-soluble polymer added to the composition may be 0.1 to 70 parts by weight, preferably 0.5 to 50 parts by weight based on 100 parts by weight of the total skin cleanser composition. This is because a film is not formed when the water-soluble polymer content is 0.5 parts by weight or less with respect to 100 parts by weight of the total composition, and when 50 parts by weight or more is used, bubble formation is lowered and the cleaning effect is lowered.

The surfactant is used to form a foam (bubble) of the skin cleanser, and the surfactant may include at least one selected from the group consisting of anionic surfactants, amphoteric surfactants and nonionic surfactants. have. In particular, when the anionic surfactant is used as a constituent of the skin cleanser according to the present invention, it can quickly foam upon contact with water and increase the cleansing effect. In addition, it serves to alleviate skin irritation, and when using a non-ionic surfactant, it has the characteristics to increase the texture of the foam and enhance the stability of the prescription, but is not particularly limited thereto.

The anionic surfactant that can be used is a carboxylate compound obtained by neutralizing a fatty acid having 8 (C8) to 24 (C24) carbon atoms, preferably having 8 to 8 carbon atoms (C8) or a mixture of these fatty acids with an alkali metal hydroxide. Selected from the group consisting of lower alcohols, higher alcohols, alkyl ethers, sulfate compounds comprising sulfates of olefins, sulfate compounds including alkylbenzenesulfonates, and phosphate compounds phosphorylated lower alcohols or higher alcohols It may include one or more.

In addition, the amphoteric surfactant that can be used may include one or more selected from the group consisting of imidazoline derivatives, betaines and sulfobetaines.

In addition, nonionic surfactants that can be used include fatty acid alkanol amides, alkyl polyglucosides, higher fatty alcohol ethoxylates, alkylphenol-polyethylene glycols, alkylated-polyethylene glycols, fatty amine ethoxylates, polyproylene glycol ethoxyls One or more selected from the group consisting of late, sorbitol ester and polyglycol ether.

Among the alcohols usable as the surfactant, lower alcohols have 1 (C1) to 5 (C5) carbon atoms, and higher alcohols have 6 (C6) to 18 (C18) carbon atoms, preferably 12 (C12) carbon atoms. ) To 18 (C18), and the substituted alkyl group has 1 (C1) to 24 (C24) carbon atoms, preferably 8 (C8) to 20 (C20) carbon atoms, and more preferably 6 ( C6) to 24 (C24).

The amount of the surfactant added to the composition may be 1 to 70 parts by weight, preferably 1 to 50 parts by weight, based on 100 parts by weight of the total skin cleanser composition. Because, when the surfactant content is less than 1 part by weight based on 100 parts by weight of the total composition, it is difficult to form bubbles due to the difficulty of forming bubbles, and when it is 50 parts by weight or more, the product is hard to be broken and a film type is not formed. This is because there is a problem.

In addition, the composition may further include a plasticizer to provide flexibility and molding of the film, and usable plasticizers include one or more selected from polyhydric alcohols including glycerin, propylene glycol and polyethylene glycol. can do.

The amount of the plasticizer added to the composition may be 0.01 to 30 parts by weight, preferably 0.01 to 20 parts by weight, and more preferably 0.01 to 15 parts by weight, based on 100 parts by weight of the total skin cleanser composition.

In addition, the composition may further include an additive, and available additives include ethylene diamine tetraacetate (EDTA), a moisturizing agent, a conditioning agent, a preservative, a transparent agent (sugar, alcohol) and a pigment which are commonly used in skin cleanser compositions. It may include one or more selected from the group consisting of, but is not particularly limited thereto.

Thus prepared skin cleanser composition according to the present invention because it has a fast solubility in water, stability under high humidity conditions, the formation of rich bubbles, and less irritation to the skin and excellent moisturizing, film-type skin cleanser containing it as an active ingredient It can be usefully used to prepare.

Accordingly, the present invention provides a skin cleanser, preferably a film type skin cleanser, containing the composition as an active ingredient.

The film-type skin cleanser may further include a plasticizer to provide flexibility and molding of the film, and usable plasticizers include one or more selected from polyhydric alcohols including glycerin, propylene glycol and polyethylene glycol. It may include.

The amount of the plasticizer may be 0.01 to 30 parts by weight, preferably 0.01 to 20 parts by weight, and more preferably 0.01 to 15 parts by weight, based on 100 parts by weight of the total skin cleanser composition.

As described above, the skin cleaner composition containing mannitol according to the present invention has a fast solubility in water, stability under high humidity conditions, and an effect of enhancing moisture retention of the skin, and thus may be usefully used as a skin cleaner.

Experimental Example  1: Measurement of Water Absorption Rate and Solubility of Skin Cleanser Composition

After preparing a film of 50 ± 10 ㎛ thickness using the raw materials shown in Table 1, was prepared at 5 × 5 cm, the prepared film was stored for 24 hours at 25 ℃, moisture conditions of 80% relative humidity and then moisture Absorption rate was measured. In addition, in order to measure the solubility of the film, 600 mL of the beaker was filled with 500 mL of water and the temperature was maintained at 25 ℃, a 50 ± 10 ㎛ thick film was prepared at 3 × 5 cm.

When measuring the water absorption rate and solubility of the film, the reason why the two films used are different from each other is that when the water absorption rate is measured, the larger the film area, the smaller the error rate when measuring the water absorption rate. When the solubility is measured, it is prepared only in a rectangular form for easy observation in a beaker, and the thickness of the film used is prepared by selecting a usable thickness when commercialized. The thus prepared film was completely immersed in water at a constant rate and then the time of complete release in water was measured. The results are shown in Table 2.

As shown in Table 2, as a result of measuring the water absorption rate and solubility, Examples 1, 2 and 3, which are skin cleaner compositions containing mannitol, have a water absorption rate under humid conditions compared to Comparative Examples (1, 2 and 3). This low and the product itself was not sticky, it was confirmed that it dissolves relatively quickly in water (Table 2).
