Description

Cosmetic composition containing balm extract {COMETIC COMPOSITIONS CONTAINING EXTRACT OF CHESTNUT}

The present invention relates to a cosmetic composition, and more particularly to a cosmetic composition containing a chestnut (Chestnut) extract is excellent in improving skin moisturizing power and skin tone (brightening) effect by exfoliation.

Skin is the organ that protects the body from external harmful environment and is located in the outermost part of our body. It consists of three layers of epidermis, dermis, and subcutaneous fat tissue, and the nerves, blood vessels, sweat glands, sebaceous glands, and apocrine glands. , Hair is present. The overall thickness of the skin is 1.5-4.5 mm, and the average thickness of the epidermis is known to be 0.4-1.5 mm. Keratinocytes, the main component of the epidermis, are divided into four layers depending on the degree of differentiation, from the innermost to the basal layer, the spinous layer, the granular layer and the horny layer. ) At this time, keratinocytes are connected to each other by a desectome and are tightly coupled to each other. The keratin cells are keratinized to produce keratin, which increases the size of the cells and flattens them to differentiate, resulting in the loss of organelles and dehydration. After the process, it is finally eliminated. In the normal state, the formation and detachment of keratinocytes is maintained at a constant rate, thereby maintaining a constant thickness of the stratum corneum.

The process of exfoliation of keratinocytes is not yet known exactly, but it is known that all intercellular lipids, proteases, moisture, and the like are involved. The stratum corneum consists of about 40% protein, 40% moisture, and 10-20% lipids, of which the keratinocytes filled with protein and the lipids filling the cells are the main functions of the skin barrier. Known. Ceramides, cholesterol, free fatty acids, etc., which are the major lipids in the skin barrier, are increased in the stratum corneum to the top, and, on the contrary, as the amount of the collagen decreases, the binding between the cells becomes weak. At this time, proteolytic enzymes such as SCCE (stratum corneum chymotryptic enzyme), SCTE (Stratum corneum tryptic enzyme), and SCTP (stratum corneum thiol protease) decompose the collagen to allow the exfoliation of keratinocytes.

Proper dehydration of keratinocytes requires proper dehydration of proteolytic enzymes. Therefore, the moisture content of keratinocytes is important, moisture control in the stratum corneum is largely controlled by two factors. The first is the natural moisturizing factor, NMF (Natural Moisturizing Factor), which is released from granule cells and consists of amino acids and metabolites, which are degradation products of filaggrin. Second, ceramides, cholesterol, and free fatty acids may be cited as keratinocyte intercellular lipids, which are synthesized in keratinocytes and secreted out of cells in the process of differentiation from the granule layer to the keratin layer to form intercellular lipids. They act as a barrier to inhibit the evaporation of water into the external environment by passive diffusion of water supplied from the dermis.

As described above, the skin has the ability to hold water away from the evaporation of moisture and retain moisture by NMF, but the skin is always exposed to the external environment such as stress, sunlight, and air pollution, and naturally undergoes skin aging. Loses moisture and leaves dry skin. In normal skin, dead keratinocytes fall off the epidermis and new cells are formed, which is a 28-day cycle.However, exposure to the external environment is severe, defects in the skin barrier, and problems in the differentiation of keratinocytes occur. Drying of the skin becomes severe.

Accordingly, due to dry skin, the production and desquamation of keratinocytes is abnormal, the differentiation of keratinocytes is not normal, the reduction of NMF, a natural moisturizing factor, and the amount of intercellular lipid components, Drying the skin becomes more severe. As a result, a lump of keratinocytes is formed, the skin surface is roughened, and the overall skin tone becomes cloudy.

Therefore, in order to maintain moisturization and improve skin tone smoothly and brightly, the differentiation of keratinocytes should be promoted, the activity of proteolytic enzymes involved in the exfoliation of keratinocytes should be maintained, and the three lipid components constituting the skin barrier. While promoting biosynthesis, adequate moisture should be supplied to the stratum corneum by NMF.

However, the cosmetic composition according to the prior art has not been able to devise a means for exerting such an effect, and did not aim to improve the moisturizing power and skin tone by removing keratinocytes.

The present invention is to solve the problems of the prior art as described above, by containing a component that can remove the exfoliation of the skin, the moisturizing power is improved through the exfoliation of the skin, skin tone (skin tone) improvement and brightening ( An object of the present invention is to provide a cosmetic composition having excellent brightening effect.

In order to achieve the above object, the present invention provides a cosmetic composition containing a chestnut (Chestnut) extract. The balm extract, according to the present invention is contained as an active ingredient for exfoliation. Specifically, the chestnut extract exhibits the action of iii) promoting keratinocyte differentiation, ii) promoting intercellular lipid synthesis, iii) promoting keratin layer protease activity, or iii) iii) to iii), effectively exfoliating keratin. Remove The chestnut extract is preferably contained in 0.001 to 30.0% by weight based on the total weight of the composition.

The cosmetic composition according to the present invention, the skin exfoliation is effectively removed by the inclusion of the chestnut extract, while improving the skin moisturizing ability, exerts a skin tone improvement and brightening effect.

Hereinafter, the present invention will be described in detail.

The present inventors have repeatedly studied to improve the moisturizing power and the dull skin tone by removing the dead skin of the skin naturally, and found that Chestnut extract is effective to remove the dead skin of the skin. Specifically, chestnut extract promotes the differentiation of keratinocytes, promotes biosynthesis of lipid components that make up the skin barrier, and promotes the activity of proteolytic enzymes involved in the exfoliation of keratinocytes. The present invention has been completed. In addition, the chestnut extract has excellent skin safety and can be used for sensitive skin as it has no skin irritation and thus can be usefully applied to cosmetic compositions.

Chestnut is an oak chestnut ( Castanea) crenata Siebold & Zucc ) Fruit, which grows at 100 ~ 1,100m in Korea, and is cultivated in southern areas such as Buyeo, Gongju, and southern areas such as Hadong, Sancheong, Gwangyang, Sunchang, and Imsil. Flowers bloom in June-July, with female and male flowers blooming together in the axilla, and Isaac's ear is a euphoric flower (animal long tail). The female flower is gathered at the bottom of the male flower head by two or three clusters. Fruits ripen in September-October and become 3-cm long thorny chestnuts, with 1-3 chestnuts in it.

The cosmetic composition according to the present invention contains the above night extract as an active ingredient. The balm extract is contained as an active ingredient for exfoliation. The chestnut extract can be obtained using the various extraction methods known in the art after removing the chestnut. For example, chestnuts may be prepared in various extraction solvents, preferably (a) water, (b) anhydrous or hydrous lower alcohols (methanol, ethanol, propanol, butanol, etc.) having 1 to 4 carbon atoms, (c) acetone, (c) It can be extracted and obtained using one or more mixed extraction solvents selected from the group consisting of ethyl acetate, (e) chloroform, and (f) 1,3-butylene glycol.
