Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition, and more particularly to a cosmetic composition having an excellent effect of improving rough skin.

[0002]

2. Description of the Related Art Allantoin, aloe extract, ginseng extract, placenta extract, bovine blood deproteinization product, fermented metabolites, etc. are known as medicinal components conventionally used for improving rough skin. . However, cosmetics containing these drug components cannot obtain sufficient effects, and development of cosmetics having more excellent action has been desired.

On the other hand, perilla oil contains a large amount of α-linolenic acid which is a kind of ω-3 polyunsaturated fatty acid, and when applied to the skin, moisturizes and prevents the skin from becoming bulky. Are known. Also, this α-linolenic acid is
It is metabolized in the body to eicosapentaenoic acid and docosahexaenoic acid. These ω-3 polyunsaturated fatty acids are currently found to have an anti-cancer effect and an effect of reducing the production of leukotrienes that cause allergic reactions,
It is getting attention.

DISCLOSURE OF THE INVENTION The present inventors have focused on the above-mentioned action of sesame oil and attempted to add it to a cosmetic, particularly a cosmetic having a rough skin improving action. However, when the sesame oil is blended alone, the rough skin improving effect cannot be said to be sufficient, and due to the influence of other bases etc., the actual effect of this cannot be sufficiently exerted. It was

Further, there is a limit to the action and effect when the perilla oil is blended at a high concentration for the purpose of obtaining a higher effect.
On the contrary, there is also a problem that due to the generation of the unique color and odor of these compounds themselves, there are restrictions on the amount of formulation, formulation, etc. in terms of products.

[0006]

In view of the above circumstances, the inventors of the present invention have conducted earnest studies to sufficiently bring out the action of perilla oil. As a result, they have found that by combining these with a specific compound, an excellent effect of improving rough skin can be stably and synergistically achieved, and the present invention has been completed.

[0007] That is, the present invention provides a cosmetic containing sesame oil and an extract of one or more kinds of plants selected from sorghum, psyllium, lily, toki and astragalus.

The perilla oil is isolated and purified from the fruits of perilla belonging to the Lamiaceae family by a commonly used method, and the method is not particularly limited. Also, the main component α
-Included are those in which linolenic acid is further concentrated to increase its content, or oil and fat compositions prepared by mixing these other components.

The perilla oil may be blended with the cosmetic of the present invention as it is, or may be refined by steam distillation, activated carbon treatment, acid clay treatment, or the like.

The content of perilla oil in the cosmetic of the present invention is 0.0001 to 10% by weight (hereinafter simply referred to as "%"), and more preferably 0.01 to 5%.
If the content is less than 0.0001%, a sufficient effect may not be obtained, and even if the content exceeds 10%, no further increase in the effect is observed, and instead, coloring and odor are generated. Also, depending on the dosage form, problems such as precipitation may occur on the product side.

On the other hand, in the present invention, the other essential components such as extracts of plants such as sorghum, saccharum, lily, Japanese tallow and astragalus (hereinafter referred to as "plant extract") are all of natural origin and have been conventionally used. It is an ingredient blended in cosmetics.

The extraction method for obtaining these plant extracts is not particularly limited in the purification treatment method, and can be obtained according to a conventional method. For example, water as an extraction solvent; primary alcohols such as methyl alcohol and ethyl alcohol; liquid polyhydric alcohols such as propylene glycol and 1,3-butylene glycol; lower alkyl esters such as acetic acid ethyl ester; hydrocarbons such as benzene and hexane. A method using a known solvent such as ethyl ether or acetone is adopted, and these solvents can be used alone or in combination of two or more kinds. Among them, preferred extraction solvents include aqueous solutions of water-miscible organic solvents, particularly ethyl alcohol, methyl alcohol, acetone and the like.

The content of these plant extracts in the cosmetic of the present invention is generally 0.0001 to 5%, preferably 0.0
It is 01 to 3%. The content of plant extract is 0.0001
If it is less than 5%, a sufficient effect may not be obtained, and even if it exceeds 5%, the effect is almost constant and its increase is not observed.

Further, in the cosmetic of the present invention, in addition to the above-mentioned essential components, an aqueous component, a powder, a surfactant, an oil, a moisturizing agent which are used in ordinary cosmetics, in the range not impairing the effects of the present invention. Agents, alcohols, pH adjusters, antiseptics, pigments, antioxidants, ultraviolet absorbers, thickeners, fragrances, cosmetic ingredients and the like can be appropriately added as necessary.

The cosmetic composition of the present invention can be produced in a conventional manner by mixing the above-mentioned sesame oil, which is an essential component, and a plant extract, and can be produced according to a conventional method, such as emulsion, cream, lotion, beauty essence, cleansing, pack. It can be applied as a cleaning agent, foundation, etc.
