Description

Composite powder for color cosmetics containing haute beta glucan and avenanthramid {COMPOSITE®POWDER COMPRISING OAT β-GLUCAN AND AVENANTHRAMIDE}

The present invention relates to a composite powder for color cosmetics comprising oat beta glucan and avenanthramid, and a powder type color cosmetic composition comprising the same, and more particularly, an oat kernel extract having an effect of improving skin roughness and improving skin moisturizing power. By applying complex powder coated with ino beta glucan and avenanthramid to porous silica and coated with silicone oil to powder type color cosmetics, it is possible to solve the problem of blending water-based color cosmetics with water-soluble active ingredients and the limitations of water use. Complex powder for cosmetics containing oat beta glucan and avenanthramid that can overcome, discoloration and odor and maximize skin moisturizing effect and produce brighter and brighter makeup and powder type color tone It relates to a cosmetic composition.

Conventional color cosmetics have been developed with the main function of covering the skin defects such as freckles, blemishes, blemishes, etc., but expressing the skin color beautifully. Recently, there has been a change in the direction of developing cosmetics in which natural care, skin care elements such as sunscreen and treatments are added. In particular, the same cosmetic formulation technology as the basic cosmetics has been researched and developed for the skin care effect, especially the moisturizing effect.

Foundations in color cosmetics are classified into powder type foundation, O / W type emulsion type foundation, W / O type emulsion type foundation, and oil type foundation, depending on the formulation. Moisturizing varies greatly. In particular, powder type foundation is composed of powder and small amount of oil-based ingredients, so it is difficult to mix water-soluble active ingredients such as oat beta glucan and moisturizing ingredients such as polyols. It is a discontinuity. Because of this, the powder type foundation has a lower moisturizing effect than other formulations. However, in terms of simplicity and portability, the powder type foundation is the mainstream of the current color cosmetics, and has applied moisturizing effect by applying various technologies.

In the past, techniques for coating materials with excellent moisture retention properties, such as collagen, hyaluronic acid, and amino acid derivatives, have been used (Japanese Patent Laid-Open Nos. 61-69710, 60-28230, and 62-127092, etc.). ), A technique of blending a water-soluble chitin derivative and a water-soluble chitosan derivative having high moisture content into porous starch (Japanese Patent Laid-Open No. 7-76508), and a technique of coating a lipid two-molecule membrane amino acid complex on the powder (Japanese Patent Laid-Open Japanese Patent Application Laid-Open No. Hei 9-302260), a technique for coating gelatin protein fibers having a crosslinked structure and a moisturizer on powder (Japanese Patent Application Laid-open No. Hei 8-92035) has been tried.

However, even when the moisturizing ingredient is coated on the pigment, the moisturizing ingredient is separated from the pigment by sweat or sebum, and thus the moisturizing function is not exhibited, or at low humidity, the moisture is absorbed from the skin, and at high humidity, the moisture in the air is absorbed. There may be a sticky feeling, there was a problem to be careful when applying to the color cosmetics.

On the other hand, oat beta glucan is a raw material commonly used in cosmetics, and has a function of improving skin moisturizing and skin elasticity, and has been particularly used in skin care cosmetic formulations. However, when formulated, it causes a change in color, and when in contact with air, has the disadvantage of inherent odor due to rancidity.

In order to solve this problem, the acidification of the formulation is performed through a buffer solution of disodium hydrogen phosphate and citric acid or a buffer solution of potassium dihydrogen phosphate and disodium hydrogen phosphate. Efforts have been made to prevent technology (US Pat. No. 6,303,656). In addition, the application of oat beta glucan in powder type color cosmetics with extremely limited use of water is very rare.

The present invention has been made to solve the above problems, and an object of the present invention is to moisturize the skin without causing discoloration and discoloration due to rancidity when formulated and formulation problems of oat beta glucan and avenanthramid To maximize the effect, to produce a brighter and brighter cosmetics Ot beta glucan and avenanthramid composite powder for a cosmetic comprising aramid and powder type color cosmetic composition comprising the same.

Oint beta glucan and the composite powder for cosmetics containing avenanthramid according to the present invention, 1 to 10% by weight of oat beta glucan, 2 to 10% by weight of avenanthramide, 10 to 20% by weight of dipropylene glycol, 1 to 10% by weight of silicone oil and the balance is characterized by comprising a porous silica.

The composite powder may be formed by supporting a solution of the oat beta glucan and the avenanthramides in the dipropylene glycol in the porous silica.

The composite powder may be obtained by coating a surface of the porous silica on which the solution of the haut beta glucan and the avenanthramides dissolved in the dipropylene glycol is coated with silicone oil.

The porous silica constituting the composite powder may have an average particle diameter within a range of 6 to 9 μm.

According to the present invention, after dissolving oat beta glucan and avenanthhramide in a solvent of dipropene glycol, not water, the mixture is collected in porous silica and applied to powder type color cosmetics, thereby limiting the formulation of water-soluble active ingredients. It can overcome the limitations of the use of water, maximize the skin's moisturizing power without discoloration and discoloration, and produce a brighter and brighter makeup. It is a complex for color cosmetics containing oat beta glucan and avenanthramid. There is an effect of providing a powder and a powder type color cosmetic composition comprising the same.

Hereinafter, the present invention will be described in detail with reference to examples of the present invention.

These examples are only for illustrating the present invention in more detail, it will be apparent to those skilled in the art that the scope of the present invention is not limited by these examples in accordance with the gist of the present invention. .

Oint beta glucan and the composite powder for cosmetics containing avenanthramid according to the present invention, 1 to 10% by weight of oat beta glucan, 2 to 10% by weight of avenanthramide, 10 to 20% by weight of dipropylene glycol, 1 to 10% by weight of silicone oil and the balance is characterized by comprising a porous silica.

The oat beta glucan is mainly used in various fields to moisturize, improve skin elasticity and give a soft texture to the stratum corneum. The oat beta glucan is a raw material commonly used in cosmetics, and has a function of skin moisturizing and skin elasticity improvement, and has been used in particular in skin care cosmetic formulations.

The avenanthramides are derivatives of tranilast, a potent antihistamine, and are characterized by insect bites, chicken pox, dry or cracked skin, mild burns caused by sunlight, irritant detergents, reduction of itching and erythema, and lipids present in skin and hair. It is an excellent antibacterial and antioxidant peptide that inhibits oxidation.

The oat beta glucan and abenathramid are obtained from the grain oven (Avena sativa). Oats are rich in minerals such as high-quality protein, phosphorus, magnesium and calcium, and are suitable for diet foods and are effective for constipation. Oat beta glucan and abenathramid of oat extract used in the cosmetic composition of the present invention are extracted by a supercritical fluid extraction method. Here, supercritical fluid (SCF) is defined as a material in a state having a condition above a critical pressure and a critical temperature, and has a unique characteristic different from a general liquid or gas. Critical point means a limit point at which a substance can exist in equilibrium in the liquid or gas phase. Under pressure and temperature conditions below the critical point, water or carbon dioxide is present in the gaseous, liquid or solid phase. As the temperature or pressure increases, the liquid phase decreases in density due to thermal expansion, and the gas phase continues in opposing changes where the density increases with increasing pressure. The density will have the same value, and there will be no distinction between the two phases. This state is called a supercritical state, and unlike solids, it is called supercritical fluid (SCF) because it is easy to deform and has the characteristics of a free flowing fluid. For reference, the critical points of water are 221 bar and 374 ° C, and carbon dioxide is 73.8 bar and 31.1 ° C. The applications of supercritical fluids include separation by extraction and treatment of hardly degradable wastes using polymer polymerization or supercritical water oxidation. As mentioned above, research on the use of carbon dioxide, which is an environmentally friendly material and has a critical point at a low range of 73.8 bar and 31.1 ° C., is technically easy to handle and economically secured because it is abundant on the earth. . Supercritical carbon dioxide is already commercialized in supercritical fluid extraction (SFE) processes to remove caffeine from coffee or tea. In addition, a process for extracting hops, other natural products, precursors of drugs, natural oils, and environmental pollutants using a supercritical carbon dioxide has been developed or commercialized. The basic principle of supercritical extraction is that, like general extraction, when the raw material containing the extract comes in contact with the supercritical fluids, the first phase in which the volatiles are distributed in the supercritical phase and the supercritical fluids containing the extract After separation from the raw material, it can be thought of as dividing into the second step of separating the extract by controlling the temperature / pressure. In the case of supercritical extraction, in particular, in the case of carbon dioxide, it becomes a gas state at room temperature and atmospheric pressure, unlike the existing extraction process, it is possible to completely separate the extract and the solvent in the second step. Increase it to make extractable supercritical and recycle.

The oat betaglucan is used in an amount of 1 to 10% by weight based on the total composition, and abenathramid is used in an amount of 2 to 10% by weight based on the total composition. If the content is less than the above range, there may be a problem that it is difficult to expect a moisturizing effect, if it exceeds the above range is mixed with dipropylene glycol and collected in porous silica, loses the properties of the powder, becomes agglomerated form There may be a problem that can not obtain a light feeling.

The dipropylene glycol has a structure of Formula 1, a polyol moisturizing agent such as glycerin, sorbitol, propylene glycol, etc., less skin irritation than other moisturizing agents, and excellent miscibility with water-soluble active ingredients such as oat beta glucan and avenanthramid It is suitable for solvents and auxiliary moisturizers that dissolve oats betaglucan and avenanthramides.

The present inventors studied oat beta glucan and avenanthramid that can be applied to powder-type color cosmetics, and after dissolving oat beta glucan and avenanthramid in a dipropylene glycol solvent instead of water, it was collected in porous silica. By applying to the powder-type color cosmetics to solve the problems of the formulation of the water-soluble active ingredient and the limitations of the use of water, it was found out that the discoloration and odor can be completed to complete the present invention. The dipropylene glycol functions as a solvent of the oat beta glucan and avenanthramid to enable uniform support on the porous silica, and when the amount of the dipropylene glycol is less than 10% by weight, There may be a problem that can not sufficiently dissolve haute beta glucan and avenanthramide, on the contrary, if it exceeds 20% by weight, after being collected in porous silica, the powder loses its properties and becomes agglomerated to obtain a light feeling of use. There may be a problem of not being able to.

The porous silica has a structure represented by the following formula (2), it is preferable that the average particle diameter in the range of 6 to 9㎛ as inorganic fine particles.

If the average particle diameter of the porous silica is less than 6㎛, there may be a problem that the trapping ability of the dipropylene glycol dissolved in the haute beta glucan and avenanthramide is so small that the particles are too small, on the contrary if the particle exceeds 9㎛ Too large to feel the roughness when applied to the cosmetic powder-type cosmetics floating, there may be a problem that the adhesion is poor.

On the other hand, the present inventors, in the case of the method of coating the powder surface with a moisturizer, knows that there is a disadvantage in that the moisture resistance is improved, but the water resistance is poor, and surface treatment (coating) with silicone oil to improve this. That is, the composite powder supports the oat beta glucan, avenanthramid, and dipropylene glycol on the porous silica, and the oat beta glucan, avenanthramid, and dipropylene glycol on the porous silica coated with silicone oil. Is done. After such a surface treatment, when applied to the skin, it was confirmed that the moisturizing ingredient gradually bleeds out and excellent in both water resistance and moisturizing power.After makeup, sebum or sweat secreted over time is absorbed by porous silica and more brightly expressed The present invention can achieve this. The silicone oil used for the surface treatment has a structure of Formula 3 below.

Wherein R is selected from the group consisting of hydrogen, methyl, fluoroalkyl (alkyl is an alkyl group of 1 to 20 carbon atoms), alkyl of 1 to 20 carbon atoms, aminoalkyl (alkyl is 1 to 20 carbon atoms), fatty acid or epoxy It may be selected, X and Y may be an integer of 15 to 20 as the same number of integers, more preferably, the sum of X and Y may be an integer of 30. It can be understood that the silicone oil as such a coating agent is known to those skilled in the art to the extent that it is commercially available and can be used. Examples thereof include the product names KF-99P and KF-9901 of Shinwol Chemical Co., Ltd. , KF-9908, KF-9909 and KP-574, but the present invention is not limited thereto.

The composite powder may be formed by being supported on the porous silica in a solution state in which the haut beta glucan and avenanthramide are dissolved in the dipropylene glycol. This serves to make haute beta glucan and avenanthramid homogeneously supported on the porous silica.

In addition, a powder type color cosmetic composition comprising a composite powder for color cosmetics containing oat beta glucan and avenanthramid according to the present invention, in the powder type color cosmetic composition, 1 to 10% by weight of oat beta glucan, avenan 2 to 10% by weight of tamide, 10 to 20% by weight of dipropylene glycol, 1 to 10% by weight of silicone oil, and 5 to 15% by weight of the composite powder for cosmetics comprising the porous silica as the balance and the remaining amount Characterized by comprising a cosmetic composition.

That is, the powder-type color cosmetic composition according to the present invention is generally known and commercialized by mixing the complex powder for color cosmetics containing haute beta glucan and avenanthramid according to the present invention in the cosmetic composition, to the composite powder It enhances the skin moisturizing effect by the supported oat beta glucan and avenanthramid, and provides powder type cosmetics that are easy to use and easy to use, wherein the oat beta glucan and avenanthramid are included. As described above, the composite powder for color cosmetics is 1 to 10% by weight of oat beta glucan, 2 to 10% by weight of avenanthramid, 10 to 20% by weight of dipropylene glycol, 1 to 10% by weight of silicone oil and the remaining amount.
