Description

Complex pigments and cosmetics containing them

The present invention relates to a composite pigment and a cosmetic containing the same modified the surface of the cosmetic pigments in order to increase the moisturizing power of the cosmetic and to increase the persistence, adhesion, water resistance, spreadability, stability of the makeup.

Conventional cosmetic pigments commonly used in cosmetics include inorganic pigmented pigments such as titanium dioxide, zinc oxide, bluish blue, ultramarine blue, iron oxide, chromium oxide, glass such as nylon powder, cellulose powder, acrylate powder, and organic tar pigments. Pigments and extender pigments such as kaolin, talc, mica, sericite, cray and silica are mainly used.

In general, cosmetic powders have a bad adhesion to the skin and apply to the skin, and after a long time, the excitation and fall out of the poor sustainability, and also has a weak moisturizing power has the disadvantage of easy drying. In addition, since the water resistance is weak and easily stained and stained by sweat or water, it is very difficult to use these powders alone in cosmetics.

In order to solve the disadvantages of such pigments, such as adhesion, moisturizing, long-lasting, water resistance, most cosmetics include glycerin, sorbitol, propylene glycol, 1,3-butylene glycol, polyethylene glycol, glycyrrhetinic acid, methylgluses, chitosan, 0.2-30% by weight of moisturizers such as sodium lactate, liquid paraffin, avocado oil, camellia oil, rosin, mink oil, olive oil, lanolin, isopropyl palmitic acid, castor oil, myritic lactate, octyldodecanol, walnut colostrum oil, octyl palmi 0.1-60 weight% of oily components, such as a tate, a dioctyl adipate, a cetyl octanoate, and jojoba oil, are used. However, if you use less moisturizers and oily ingredients, the skin becomes rough and the skin becomes rough, and if you use too much oily feeling is poor adhesion and poor sustainability, it is difficult to produce a cosmetic that satisfies only the moisturizer and oily ingredients.

In order to improve these disadvantages, the method of coating the surface of the pigment with various moisturizers, oily ingredients, sebum-like ingredients and the like to improve the adhesion, moisturizing power, durability, water resistance, etc. has been recently performed. I didn't get it.

The present inventors have tried to solve the above problems by coating 1-4 grams of sodium hyaluronate in 100 grams of cosmetic powder such as mica, talc, titanium dioxide, etc., but the surface is smooth by the biopolymer sodium hyaluronate. Although it was desirable, the moisturizing power was still weak and the adhesion to the skin was poor, which took a long time to finish.

Accordingly, an object of the present invention is to coat a cosmetic pigment with a raw material excellent in moisturizing power and adhesion and a raw material to increase the persistence and water resistance to increase the sustainability, moisturizing effect, water resistance, adhesion, spreading of the cosmetic and containing it It is to provide cosmetics.

The present inventors first coat the anionic material on the pigment and then coat the hydrolyzed ginseng saponin hydroxypropyltrimonium chloride which has been previously applied for a new patent (Domestic Manufacturing Patent No. 26476, Domestic Material Patent Application No. 89-8129). When moisturizing ability and adhesion was found to improve.

In addition, in a preferred embodiment of the present invention, the anionic material is first coated on the cosmetic pigment, and the hydrolyzed ginseng saponin hydroxypropyltrimonium chloride is coated as the secondary coating film, and then the oily component is thirdly coated thereon. In the preparation of composite pigments, these pigments exhibit significant improvements in sustainability, moisturizing effect, water resistance, spreadability and adhesion.

The above process is described in more detail by coating 0.1-6.0% by weight of cationic hydrolyzed ginseng saponin hydroxypropyltrimonium chloride again on a cosmetic pigment coated with an anionic material of 0.1-5.0% or less, and using squalane, liquid paraffin, Oily components such as methyl polysiloxane were coated with 0.1-10.0% by weight to improve the durability, moisturizing effect, water resistance, spreadability and adhesion.

Hereinafter, in the present invention,% means weight%.

Cosmetic pigments used in the present invention are inorganic pigments, organic pigments, organic pigments, inorganic pigments, various natural pigments and the like.

Anionic substances are sodium or potassium salts such as citric acid, lactic acid, myristic acid, palmitic acid, stearic acid, licorice acid, amino acids, hyaluronic acid and chitosan.

Oily components include higher alcohol oils, hydrocarbon oils, ester oils, ether oils, silicone oils, lanolin derivatives, and various natural oils.

When explaining the effects of the present invention, hydrolyzed ginseng saponin hydroxypropyltrimonium chloride obtained by hydrolyzing and cationic saponins extracted from ginseng has a cationic structure, which has a good affinity with the skin. Therefore, it has very good adhesion to skin and has excellent moisture retention ability because it has excellent moisture retention ability.

Compression molded powder products use a large amount of oil-based components to increase moldability and reduce breakage. This makes oily feeling and hard to get contents on the brush. However, the ginseng saponin derivatives used in the present invention have excellent binding strength with cosmetic pigments, and even when a small amount of an oily component is used, the breakage rate of the contents is remarkably reduced and the moldability is good, so the product has excellent stability and a good feeling. It can manufacture. That is, since the cosmetic pigment was surface-modified with these substances, the cosmetic powder coated with hydrolyzed ginseng saponin hydroxypropyltrimonium chloride has excellent feeling of use, moisturizing effect, and stability. In addition, to prevent the volatilization of moisture contained in these moisturizers and to increase the durability and water resistance, since the third coating film is formed with an oil component, the moisturizing property is excellent in durability. It is not erased or stained, so the water resistance is good.

As a result, the composite pigment according to the present invention has the effect of improving the sustainability of cosmetics, enhancing the moisturizing effect, strengthening the water resistance, and increasing the adhesion and stability.
