Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition for skin whitening,

The present invention relates to a skin whitening cosmetic composition comprising a horseshoe mushroom extract, and more particularly, to a cosmetic composition for skin whitening derived from a natural product, which has a free radical scavenging ability and a tyrosinase activity inhibiting ability through a horseshoe mushroom extract .

Today, oriental women prefer white, clean skin like white whiting and use it as an important criterion of beauty. Therefore, whitening agents are actively being developed to treat skin pigmentation abnormalities and meet beauty needs.

The skin color of a person depends on internal and external factors. Among them, melanin, the natural skin pigment, is the most fundamental internal color. Melanin is synthesized in the melanocyte, a pigment cell in the basal layer of the epidermis. This melanocyte is a nerve-derived cell, and it plays an important role in protecting the skin from ultraviolet rays by generating melanin.

Melanocytes are morphologically similar to dendritic cells with dendritic spines, and have many receptors for many signaling and growth factors, and there are many features that indicate that the origin of the melanin is the same as neurons.

Melanocytes are affected by various factors such as ultraviolet rays, external conditions such as inflammation, hormones such as α-MSH, cytokines such as IL-1, TNF-α and GM-CSG, and leukotrienes. In addition, in order for melanin to be produced from melanocytes, several kinds of genes are involved in the action of various genes such as tyrosinase, TRP-1 and TRP-2 and their enzymes, and melanin migration into keratinocytes .

To briefly describe the formation of melanin, tyrosine is first converted to DOPAquinone via DOPA by an enzyme called tyrosinase in melanocyte endoplasmic reticulum in melanocyte, (DOPAchrome) through enzymatic reaction and autoxidation reaction to produce melanin as a dark brown copolymer. The resulting melanin is transferred to the keratinocyte through melanoma, and after about 28 days of keratinization, it exits the skin surface and disappears with the keratinocytes.

In the development of a whitening agent for preventing melanin pigment deposition, there is known a method of decolorizing by reducing the melanin pigment presently produced and a method of inhibiting the activity of tyrosinase, an enzyme that forms a melanin pigment. However, it is known that whitening agents using tocopherol, vitamins and the like, which are used for reducing the melanin pigment, have little discoloring effect on the melanin pigment, and inhibitors that inhibit the activity of tyrosinase have been attracting attention .

Free radicals and reactive oxygen species, which are highly reactive in skin aging, are common causes of extrinsic aging and endogenous aging. As a person gets older, antioxidant enzymes such as antioxidant enzymes and vitamin E, C, glutathione, and ubiquinol are reduced in the body, resulting in an imbalance of oxidation and antioxidation, thereby promoting the melanin production reaction, , Which causes skin elasticity, wrinkles and stains, and exogenous skin aging such as freckle formation. Therefore, a whitening composition that inhibits the activity of tyrosinase and has an antioxidative effect can more effectively induce a skin whitening effect.

In the conventional cosmetics field, as a whitening ingredient, for example, substances inhibiting tyrosinase enzyme activity such as kojic acid and arbutin, hydroquinone, L-ascorbic acid ), Derivatives thereof and various plant extracts have been used. However, since the substance inhibiting the tyrosinase enzyme activity is low in stability in the prescription system, it is decomposed and colored, its use is limited due to the generation of offensive odor, efficacy at the living body level, uncertainty of the effect, It is true.

On the other hand, the mushroom ( Fomes fomentarius (L.) J. Kickx f. ) Is a perennial, and the entire mushroom is horseshoe-shaped or hemispherical, covered with thick husks, surface is grayish white or grayish brown, have.

Hereinafter, the present invention will be described in more detail by way of examples. The following examples are intended to further illustrate the present invention, and the scope of the present invention is not limited by these examples.

[Example 1] Preparation of extract

The horsetail mushroom, Daechunbyeol, the diatomaceous mushroom and the weevil broth dried in the Kyungdong medicinal product market were purchased, and 2 kg of the dried product was uniformly crushed and then immersed in 10 L of methanol for 2 days. The extract was filtered twice , And the filtrate was concentrated with a concentrator to obtain respective methanol extracts.

[Example 2] Antioxidative effect test of extract

The antioxidative effects of the methanol extracts of the horseshoe mushroom, Daechonjang, Klebsiella crassifolia, and the weevil flea marketed in Example 1 were compared and evaluated.

2-1. DPPH (1,1-diphenyl-2-picryhydrazyl) radical scavenging activity experiment

DPPH (1,1-diphenyl-2-picryhydrazyl) radical scavenging activity test is a widely used simple antioxidant detection method, and is a method widely used for the measurement of antioxidative activity of phenol and aromatic amines.

DPPH, a kind of dye, exhibits a strong absorption band at 525 nm due to the odd electrons it has. However, when reacting with an electron donor such as phenol or a hydrogen donor, electrons or hydrogen radicals are generated from the donor, and the absorption band disappears and becomes a stable molecule. In addition, the donated electrons are irreversibly bound, and the color of purple DPPH gradually decreases in proportion to the number, and the color of the reaction solution turns yellow. The radical scavenging activity can be determined by measuring the value of the absorbance thus decreasing.

The DPPH radical scavenging activity experiment was applied by Blois method. 100 μl of a 0.4 mM DPPH solution dissolved in methanol was added to a 96-well plate, and 100 μl of each of the samples was dissolved in methanol at each concentration. The mixture was uniformly mixed with a vortex mixer, and incubated in a dark room for 30 minutes And the absorbance was measured at 517 nm.

In the control group, methanol was added instead of the example, and methanol was added in place of the DPPH solution to obtain a correction value. As a comparative example, Butylatd Hydroxy Anisole (BHA) was used. The free radical scavenging ratio was calculated according to the following formula, and the results are shown in Table 1.
