Description

Cosmetic compositions containing red ginseng concentrate collectors {Cosmetic compositions with adsorber stabilized with concentrated red ginseng extract}

The present invention relates to a collector coated with a moisturizer after collecting red ginseng concentrate in a lauryl methacrylate / glycol dimethacrylate crosspolymer or an allyl methacrylate crosspolymer, and a cosmetic composition containing the collector. In detail, red ginseng concentrate is adsorbed on lauryl methacrylate / glycol dimethacrylate cross polymer or allyl methacrylate cross polymer to make cosmetics with less stickiness and excellent stability and usability without color or brittleness due to temperature change. The present invention relates to a coated collector and a cosmetic composition containing the collected after the coating.

Red ginseng, which is the raw material of red ginseng, contains about 75% of moisture, so it is difficult to store for more than a week, so it is widely distributed as a simple dry white ginseng. The climate is the most ideal for ginseng cultivation, and the quality and efficacy are known to be superior to those of China.

Saponin, the main ingredient of red ginseng, is a substance commonly contained in roots, stems, leaves, bark, and seeds of plants, and is widely used in medicine and health foods. Saponin, the main ingredient of red ginseng, is a chemical compound called glycoside. Saponin is a name given to foam like soap when shaken. Saponin-containing plants have been used in medicine for the purpose of washing, expectoration and antitussive. It is widely used in health, stomach, drainage, anti-tumor, diuresis, tonic and gangjeong.

Saponins are glycosides consisting of sugar (sugar or glycone) and non-sugar (a-glycone). Red ginseng saponins are triterpenoid dammarane saponins. exist. Red ginseng promotes the non-enzymatic browning reaction during the steaming process, and many browning reaction products are formed. Among them, a large amount of antioxidants such as maltol are generated, which inhibits cancer cell proliferation. Ingredients such as panaxytrol are produced. Saponins are also found in bellflower, soybeans, and ginkgo. Especially, saponins contained in ginseng, red ginseng, and wild ginseng are called ginsenosides. Ginsenosides Rh2 and Rg3 are not present in ginseng at all and are contained only in wild ginseng and red ginseng.

The skin action of these red ginseng components improves skin function, and helps to maintain skin elasticity and anti-aging, rejuvenation of skin cells, moisturizing, resolving skin problems, tired skin improvement, and maintaining healthy skin from harmful environment. In recent years, herbal cosmetics have become popular, and red ginseng extract, ginseng extract, wild ginseng and camphor ginseng are widely used in cosmetics.

In the present invention, the term 'red ginseng concentrate' refers to a concentrated and extracted soluble red ginseng component from red ginseng as defined by the Food Code (published by the Korea Food Industry Association). That is, the red ginseng concentrate contains more than 70mg / g of red ginseng component saponin. This red ginseng concentrate has a very sticky and unusual odor and color. When applied to cosmetics using the red ginseng concentrate as it is, the red ginseng concentrate has its own color, odor, and disturbance of the formulation by saponin that can act as a surfactant. The stability of the product may be affected, and it is known that it is not easy to commercialize due to the strong smell and color of red ginseng concentrate. On the fragrance side, even if the red ginseng concentrate is blended to the cosmetics at about 0.25% or more, the general consumer has a sense of rejection due to the strong odor of the red ginseng concentrate. Difficult to apply Saponin contained in red ginseng concentrate has surfactant activity, so it interferes with the surfactant which plays a role in stabilization of the formulation in cosmetics and affects the stability of cosmetics. Therefore, surfactant or stabilizer is added to maintain stability. It is necessary to mix | blend with. However, this addition may cause stickiness that causes a disapproval of use, or the use of color cosmetics may cause a jungle phenomenon, which may result in poor color cosmetics. We therefore studied the development of a formulation containing red ginseng concentrates stably.

The present inventors conducted a stabilization study to be able to use the red ginseng concentrate useful in cosmetics, which is stable and easy to change in temperature without having the problem of the red ginseng concentrate, and as a result, lauryl methacrylate / glycol dimethacrylate. After adsorbing the red ginseng concentrate on the cross polymer or allyl methacrylate cross polymer, it was found that the above-mentioned objects can be achieved by making a collector coated with a moisturizing agent and applying it to a cosmetic.

Accordingly, it is an object of the present invention to provide a cosmetic collector in which red ginseng concentrate is stably adsorbed.

Still another object of the present invention is to reduce the specific odor of the red ginseng concentrate containing the coating collector, and to provide a stable and usable cosmetic composition.

As used herein, the term 'red ginseng concentrate' refers to a concentrated and extracted soluble red ginseng component from red ginseng as defined by the Food Code (Korea Food Industry Association). That is, the red ginseng concentrate contains more than 70mg / g of red ginseng component saponin.

The adsorbent used in the present invention, lauryl methacrylate / glycol dimethacrylate crosspolymer, is a white porous powder having a particle size of 200 to 1,200 μm, and has a strong property of adsorbing skin oil and good usability. to be.

The allyl methacrylate crosspolymer is a porous material having a size of about 20 μm and a surface area of 150 m ² / g or more.

As the polyhydric alcohol (polyol) used as the coating agent, butylene glycol, propylene glycol, glycerin, and the like can be exemplified, and one kind or a mixture of two or more kinds can be used. The reason why the polyhydric alcohol can be used as a coating agent is that butylene glycol or propylene glycol does not show solubility when mixed with the red ginseng concentrate itself and becomes tangled, causing precipitation, but the lauryl methacrylate / glycol dimethacryl collected with the red ginseng concentrate. Red ginseng concentrate which does not show aggregation or precipitation phenomenon in late crosspolymer or allyl methacrylate crosspolymer and prevents the release of red ginseng concentrate collected on the surface of these two porous powders to maintain stability against discoloration or discoloration and cause stickiness This is because the use of red ginseng concentrate in cosmetics can be increased by preventing the absorption into the skin quickly and improving usability.

These components are (a) red ginseng concentrate: red ginseng concentrate aqueous solution with ratio of purified water 2: 8-7: 3 (b) in lauryl methacrylate / glycol dimethacrylate crosspolymer or allyl methacrylate crosspolymer One or two selected mixtures (C) Polyhydric alcohols such as butylene glycol, propylene glycol or glycerin, or one or more mixtures of two or more thereof. The ratio of (A) :( B) is 0.5: 1 to 7: 1. After adsorbing, the adsorbed (ga + na) :( c) ratio is 0.1: 4 to 4: 4 to provide a collector prepared by mixing coating.

When the collector of the present invention is blended into various cosmetics, it may be used in an amount of about 1.50 to 25.0% by weight based on the total weight of the cosmetic. If less than 1.50% by weight of the red ginseng concentrate skin care effect is insignificant, if it exceeds 25.0% by weight is not preferable in the smell and stickiness.

The present invention is described in detail in the following Examples, but the present invention is not limited to these Examples. The content of all components in each example is parts by weight unless otherwise specified.
