Description

Self tanning composition sprayed in the form of foam

The present invention relates to a skin colorant composition sprayed in the form of a foam, and more particularly, by containing dihydroxyacetone (DHA), a surfactant and an aerosol propellant, it is uniformly applied to the skin without staining, sticky The present invention relates to a foam-coated skin colorant composition which can be kept stable for a long time without being absorbed in clothes, bedding and the like without high absorption power.

DHA has been used for medicines such as diabetes treatment since the 1920s, and after the discovery of the skin coloring effect in the 1950s, DHA has been used for coloring the skin since the late 1950s. Therefore, today, DHA is mainly used in cosmetics, also known as self-tanning products, which give the appearance of burning skin without sunbathing by coloring the skin dark brown.

This DHA is used to color the skin by reacting with amines, peptides, and free amino acids in the stratum corneum to produce a colored polymer. As the stratum corneum is removed, the skin gradually returns to its original color. Thus, many products have been developed for the purpose of coloring the skin using DHA so far, and they have been provided in the form of emulsions such as creams and lotions. However, until now, products of such formulations have an acidic pH range of about 5 to 6 suitable for coloring reactions, are incompatible with components such as amines, and have properties of being easily denatured in a strongly acidic and alkaline pH range. The formulation is very unstable. In addition, when the product is spread by hand, it is unevenly applied, and since the coating amount cannot be accurately determined by the naked eye, there is a problem in that uneven coloring is not made and stains appear. And, when the coating is felt sticky in the skin and absorption is late, there is a problem that is buried in clothing, bedding.

Therefore, in order to remedy the above disadvantages, there have been attempted products in the form of adjusting the viscosity of the contents or spraying in a spray type, but have not obtained satisfactory results.

Accordingly, the present inventors have diligently studied to solve the above problems, and as a result, by containing DHA, surfactants and aerosol propellants, the contents can be used in the form of foam spraying, and the nonuniformity of the formulation, nonuniform coloring, The present invention has been found to be able to improve problems such as inconvenience.

That is, it is an object of the present invention to provide a foam-coated skin colorant composition that can be uniformly applied to the skin when used, does not cause stains, has a high absorbency without stickiness, has a good feeling of use, and can be stably maintained for a long time.

In order to achieve the above object, the foaming skin colorant composition according to the present invention contains 1.0 to 20% by weight of dihydroxyacetone (DHA) and 0.1 to 20% by weight of surfactant based on the total weight of the composition. It is characterized by consisting of aerosol stock solution and aerosol propellant.

Hereinafter, the present invention will be described in more detail.

The foam-injection skin colorant composition of the present invention comprises an aerosol stock solution and an aerosol propellant, wherein the stock solution contains 1.0 to 20% by weight of DHA and 0.1 to 20% by weight of surfactant based on the total weight of the composition.

In the present invention, DHA is contained in an amount of 1.0 to 20% by weight based on the total weight of the composition so that coloring can occur but the content can be stably maintained for a long time.

Surfactants used for the purpose of compatibility with the aerosol propellant used to prevent separation and sedimentation of the contents in the skin colorant composition of the present invention and foam spraying are cationic, anionic, nonionic and zwitterionic. At least one selected from among them is mixed and contained in an amount of 0.1 to 20% by weight based on the total weight of the composition. Specific examples include cationic surfactants such as alkyltrimethylammonium chloride, dialkyldimethylammonium chloride and alkyldipolyoxyethylenemethylammonium chloride, monovalent metal salts of allyl-alkylsulfonate, monovalent metal salts of alkyl sulfate, and polyoxyethylene alkyl sulfate. Anionic surfactants, polyoxyethylene alkyl ethers, alkyl polysaccharides, such as monovalent metal salts, monovalent metal salts of allyl-olefinsulfonate, monovalent metal salts of olefin sulfates, monovalent metal salts of polyoxyethylene olefin sulfates, and monovalent metal salts of methylalkyltaurates , Polyoxyethylene alkyl ester, polyoxyethylene sorbitan alkyl ester, polyoxyethylene olefin ether, olefin polysaccharide, polyoxyethylene olefin ester, polyoxyethylene sorbitan olefin ester, dimethicone copolyol, polyoxyethylene tocopheryl Nonionic surfactants such as ethers And amphoteric surfactants such as cocamidopropyl betaine, alkyl betaine and olefin betaine.

As a propellant for releasing the contents from the container in the foam-injection skin colorant composition of the present invention can be selected and used without limitation, such as liquefied petroleum gas, compressed gas or air that is commonly used in aerosol containers, specific examples are trichloro fluorine Liquefied gases such as romethane, dichlorotetrafluoromethane, monochlorodifluoromethane, trichlorotrifluoromethane, dimethyl ether, propane, n-butane, isobutane, compressed nitrogen gas, compressed oxygen gas, compressed air, etc. Compressed gas, air mixed by the user's pressurization at normal pressure, and the like, and at least one selected from these are mixed and used. The amount of propellant used is 1.0 to 40% by weight, preferably 5 to 15% by weight, based on the total weight of the composition. On the other hand, in the case of using compressed gas and air, the pressure should be below 8.5 kg _f / cm ² , and in the case of air, the container should be filled with air.

In addition, the foam injection-type skin colorant composition according to the present invention may contain an appropriate amount of thickeners and moisturizers to give a smooth feeling of use and spreadability, and may use a base and a buffer solution for controlling and stabilizing pH.

Hereinafter, although an Example is given and this invention is demonstrated in detail, this invention is not limited only to these Examples.

As can be seen in Table 1 and Table 2, in the case of the skin colorant composition of Examples 1 to 3, less stickiness and excellent spreadability, the freshness can be felt, and discomfort such as staining on clothes or bedding is improved. It became. In addition, since the amount of sample used for the application of a specific area is smaller than that of the comparative example, it can be predicted that the same amount of coloring will occur evenly compared to the comparative example when the same amount is taken.

On the other hand, in Examples 1 and 2, the coloring tended to be light in the human subject's review, which is a bubble and the user tends to use a relatively small amount. The reason is that it is less, and the intensity of coloring can be increased by increasing the content of DHA as in Example 3.

As described above, the foam-injection skin colorant composition of the present invention contains dihydroxyacetone (DHA), a surfactant, and a propellant, so that when used, it is less sticky, has excellent spreadability, and absorbs quickly, so that it can be applied to clothing or bedding. The phenomenon is improved. In addition, since the formulation is stable, it can be kept stable for a long time.
