Description

Composition for maintaining skin oil and moisture balance and a cosmetic composition comprising the same {} composition for balacing sebum and moisture of skin and Cosmetic compsition comprising it

The present invention relates to a composition for maintaining skin oil and moisture balance and a cosmetic composition comprising the same.

The skin is composed of three layers of epidermis, dermis and subcutis, which are the outermost ones and play the most important role in skin aging. It is the epidermis that is the subject of the most intensive research in.

The epidermis forms the outer skin, ie, the stratum corneum, which acts as a protective barrier against various external stimuli, such as drying, ultraviolet and other physical and chemical stimuli, and is composed of three layers of living cells, namely the basal layer from below. ), Polar layer and granular layer. These three layers show the differentiation and progression of keratinocytes as the keratinocytes move to the outer part of the skin to form keratin, and new cells are formed in the basal layer to move to the epidermal layer. 'Awakening' is a series of processes in which the process of dropping and dropping is repeated.

The epidermis may cause changes in its function or structure due to the accumulation of external stimuli such as age, gender, specific site, continuous environmental stimuli, and increased stress, and through such changes, skin inflammation, aging, and other reactions may proceed. The function as a protective film falls.

In the epidermis, the components that make up the outermost stratum corneum are skin lipids, which are responsible for the skin's barrier function, which protects the skin from external harmful impurities by controlling the division and differentiation of keratinocytes. It is an important function to prevent the leakage of substances in the body and to prevent evaporation of skin moisture.

Among the lipids of the skin, the main lipids responsible for the barrier function of the skin are lipids produced by the differentiation of keratinocytes of the epidermis. These lipids fill the spaces between the differentiated corneocytes and provide the binding force between cells. It also plays a role. These lipids are mainly composed of ceramides, cholesterol and free fatty acids, and have a composition with a small amount of phytosphingosine and spingosine.

In order for the stratum corneum with the above characteristics to function normally and maintain a healthy state, it is necessary to contain at least 10 to 20% of moisture, and as the moisture content of the stratum corneum decreases, skin flexibility decreases and becomes hard, and wrinkles and dropping occur. It becomes a factor. On the other hand, the deterioration of the function as a skin protective film is a major cause of loss of self-confidence by reading health and losing beauty, and in the case of skin loss or unclear and rough skin, the moisture content of each layer is significantly reduced. .

These symptoms are closely related to the phospholipids that make up the stratum corneum. The stratum corneum components related to these symptoms are ceramide, cholesterol, free fatty acids, etc., which are about 40-65%, 10%, and Accounted for 25%.

As described above, keratinocytes in which the stratum corneum of the skin is composed of a multi-layered structure, and these keratinocytes are firmly bound by lipids filling the intercellular gap, thereby suppressing the evaporation of moisture and harmful from the external environment. It performs an important biological function of preventing the invasion of substances.

The lipid components of epidermal cells change as new cells form in the basal layer and migrate to the superficial layer, whereby the newly formed cells in the basal layer move to the stratum corneum, causing biochemical changes inside the cells, which leads to changes in lipid content. As it moves to the stratum corneum, the phospholipid content decreases and a large amount of insoluble ceramide is accumulated to form an ideal lipid barrier.

Recently, the skin protection composition for preventing and improving skin damage, relieving skin inflammation, or moisturizing has been manufactured by combining various substances extracted from natural products. As such, natural extracts used in skin protection compositions for the purpose of preventing and improving skin damage include natural polymers such as copper, plant extracts and collagen, amino acids, vitamins, and glycerin, which help to moisturize the skin. Moisturizing agents, such as and 3-butylene glycol, are used a lot.

However, in recent years, as the skin properties as described above have been revealed, by preparing a cosmetic composition containing the ceramide, cholesterol, phytosphingosine or fatty acids, which are the major components of the stratum corneum lipids to balance the composition of the skin lipid components to protect the skin Many compositions for treating cosmetic or skin diseases for imparting effects have been developed.

In general, the normal stratum corneum has a moisture content of about 10 to 30%, which makes the skin surface smooth and soft, and maintains normal body protection. However, even healthy skin tends to suffer from poor skin condition or lack of moisture due to the variable external environment. Thus, when the moisture content of the stratum corneum is less than 10%, the skin becomes rough and the body loses its protective function, causing aging.

On the other hand, according to the results of comparative analysis of normal skin and dry skin in order to examine the moisture state in the stratum corneum of the skin, it is known that dry skin has less water content than normal skin. In dry skin, the aggregation of keratinocytes deteriorates and scales come off from the surface of the skin. The dryness of the skin decreases the water content of the stratum corneum and the barrier function is not properly exhibited. Because it does not.

Cholesterol accounts for about 30% of epidermal lipids, and skin is newly produced through synthesis regardless of the amount of cholesterol in the serum. The delay in skin barrier recovery as the skin ages is caused by a decrease in the overall epidermal lipid synthesis, but can be effectively improved by applying a biolipid mixture containing a certain amount of cholesterol or more.

Patents related to such cholesterol are disclosed in the Republic of Korea Patent Publication No. 10-2008-0026956, a cosmetic composition using an intracellular lipid-like component including cholesterol, and the Republic of Korea Patent Publication No. 10-2010-0100202 is a ceramide and cholesterol Has been disclosed a cosmetic formulation for skin protection comprising the main component, the Republic of Korea Patent Publication No. 10-2011-0072022 also discloses a pack type cosmetic composition containing an intercellular lipid component such as cholesterol to improve skin moisturizing have.

Sebum is an oil-soluble substance secreted from sebaceous gland located near the skin surface. Sebum secretion is affected by age, hormones, disease, climate, season, and mental factors, and complex skin and external skin where the amount of dry skin, oily skin, neutral skin and facial oil are different according to the amount of sebum secretion The barrier function of the substance is reduced, so it is divided into sensitive skin with frequent skin troubles.

Sebum plays a role in maintaining skin health. Sebum is combined with moisture such as sweat to form a thin sebum film in the form of a weakly acidic emulsion on the surface of the skin to show the lubricity of the skin surface. It protects the skin from various forms of physical and chemical stimuli by preventing foreign entry and external moisture evaporation (TEWL / Trans Epidermal Water Loss) through the stratum corneum.

However, excessive sebum secretion may cause sebum accumulation on the surface of the skin, which may cause the skin to have a greasy or oily appearance. Excess sebum secretion may enlarge pores and cause skin problems such as acne. Can cause. In addition, water-free sebum can cause keratin and easily irritate hair follicles, making it more susceptible.

Thus, compositions that inhibit sebum secretion using extracts or absorb sebum using porous powders to reduce the amount of sebum on the surface are currently used. As an example, the cosmetic composition for inhibiting sebum containing Haesong (Gom brush) and lid vine extract disclosed in Korean Patent Publication No. 10-2006-0034124 reduces sebum secretion by inhibiting 5-alpha-reductase activity but when used as a cosmetic raw material. Immediate effect is negligible

Sebum absorbing components have the ability to absorb or remove sebum from the surface of the skin, examples of which include silica containing compounds. The sebum adsorption composition using silica compound, nylon powder and polymethacrylate, boron nitride powder, titanium oxide, zinc oxide, etc. which adsorb sebum gives immediate sebum removal effect, but the effect is temporary and at the same time absorbs moisture. Properties can cause skin dryness. In addition, excessive sebum removal has the disadvantage of reducing skin protection by removing oily substances that protect the skin. In addition, when increasing the sebum absorption ability in the long term there is a problem that the barrier is damaged due to the water retention ability has a technical difficulty in the development of cosmetics.
