Description

Astringent Cosmetic Composition Containing Yulpi Extract

The present invention relates to a convergent cosmetic composition containing the extract of Yulpi (chestnut chestnut) which is the fruit of the perennial plant.

In general, cosmetics are aimed at the aesthetic function to clean human skin or express beautiful and attractive and the defense function to protect the skin from the harmful environment from the outside. Recently, a variety of functional cosmetics have appeared as most consumers demand cosmetics having functional effects such as wrinkle improvement, whitening, blemishes, and freckles. These functional cosmetics commonly improve the skin's various troubles caused by highly reactive free radicals, free radicals and peroxides caused by harmful environment (increase in ultraviolet radiation, air pollution, stress, irregular eating, etc.). Of course, it protects the skin and helps the skin to maintain its normal function.

For example, one of the functions of maintaining healthy skin by skin protection of cosmetics is a convergence action.

The astringent effect of cosmetics is to shrink the pores and pores that are opened so that you can feel the elasticity and suppleness of the skin. The contraction of the skin has a physical action and a chemical action. The physical action is to temporarily reduce the surface temperature of the skin by the heat of evaporation when the alcohol contained in the lotion evaporates, constricting pores and pores where sebum is secreted, and converging effect, and chemical action to coagulate the organic acid or protein. Coagulation and contraction of proteins in the secretory areas of the sebaceous glands and sweat glands by the presence of substances gives a converging effect.

When astringents are applied to the skin, the effect on the skin is local. The effect of astringents is on the upright hair, tight skin (at least the skin feels tight), temporary shrinkage of pores or pores, suppression of sweating, relief of oily skin, blood coagulation of wounds, wound healing and tissue growth Promotion. Due to these many advantages, a substance having a convergence effect is recognized as an important ingredient in cosmetics. Astringents are largely divided into cationic and anionic astringents. Cationic astringents include allantoin hydroxyaluminum, allantoin dihydroxyaluminum, lead chloride, aluminum chloride, ferric chloride, zinc oxide, aluminum lactate, and the like. Zeros include citric acid, tartaric acid, tannic acid, lactic acid and malic acid. Chemically astringent astringents are classified into two groups. First, metal ions that converge with metal salts of organic or inorganic acids include iron, chromium, aluminum, zinc, lead, mercury, tin, copper, silver, and zirconium. They have a convergent effect by lowering the activity of Hanseon. The convergence effect by the metal salt is different depending on the kind of metal and the kind of anion in the salt compound, and the effect is also not high. In addition, metal ions other than zinc, aluminum, and zirconium are toxic, discolored, and irritated with skin, which is not preferable for cosmetics. Second, citric acid and lactic acid are the most commonly used low molecular weight organic acids. Third is lower alcohol. These astringents generally have the effect of precipitating proteins, causing the skin to shrink and give astringent effect.

Recently, plant extracts having astringent effects have been developed as astringents in accordance with the trend of natural cosmetics, and most of these plant extracts contain tannins or molar assets. In general, astringents that have a convergence effect are used in the preparation of a lotion. The action of the cosmetics having a convergence effect on the skin is, firstly, to keep the skin weakly acidic, and secondly to prevent skin troubles by inhibiting the development of microorganisms, and thirdly By suppressing sweating by the action to prevent the makeup to rise.

The present inventors have already applied for a patent on the whitening effect, moisturizing effect and skin wrinkle improvement effect of Yulpi extract (Korean Patent Application No. 97-4459, Korean Patent Application No. 97-58952), and research on Yulpi Extract As a result, it was found that the convergence effect is excellent in addition to the above effects, thereby completing the present invention.

An object of the present invention is to provide a convergent cosmetic composition comprising the extract.

The present invention relates to a convergent cosmetic composition comprising yulpi extract.

Yulpi extract of the present invention is contained in an amount of 0.001 to 10% by weight, preferably 0.01 to 5% by weight relative to the dry weight of the cosmetic.

Yulpi extract of the present invention is as follows.

The present invention washes the skin of the chestnut (Julpi), which is the fruit of wild or cultivated chestnut plants with clean water, and then dried and finely powdered, and water, lower alcohol as an extraction solvent for the dry weight of the powdered Yulpi powder ( For example, methanol, ethanol, propanol and butanol, etc.), a mixture of water and lower alcohol, acetone, ethyl acetate, diethyl ether, benzene and chloroform are added 1 to 15 times the weight, respectively. Next, a cooling capacitor is installed to extract the active ingredient by heating at 50 to 95 ° C. for 1 to 20 hours while preventing the active ingredient from evaporating, or extracting the active ingredient by depositing at 5 to 40 ° C. for 1 to 15 days. The extract thus extracted is concentrated under reduced pressure while recovering the solvent evaporated using a distillation apparatus equipped with a cooling capacitor to obtain the desired extract of the present invention.

Chestnut (Castanea crenata S. et Z., Castanea mollissima Bl., Castanea bulgaris), chestnut (Castanea Bungeana Bl), chestnut (Castanea crenata for. Multicarpa (Uyeki) Chung) and the like, these are deciduous leaves It is a tree growing vertically at 100 ~ 1,100m and horizontally cured throughout Korea and distributed in Japan and Manchuria. Leaves are alternate, elliptical or oblong lanceolate, blunt or heart-shaped, sharp at the ends, serrated. Flowers are hermaphrodite and bloom in May-June. Fruits are nuts, egg-shaped or obovate, parietal is spherical, thorny on the outside, ripens in September-October.

The yulpi is a dark brown bark that encloses the fruit of chestnut and is separated from the chestnut fruit and used after drying in the sun.

Converging cosmetics containing the yulpi extract of the present invention is a convergent cosmetic (skin), convergent cosmetics (after-shave skin), convergence / nutrition cosmetics (lotion), convergence / nutrition cosmetics (after-shape lotion), converging cream (perspiration cream) Cream) or a convergence pack.
