Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cosmetic compositions,

The present invention relates to a cosmetic composition for supplying a useful ingredient lost by washing to the skin, and a method for supplying a useful ingredient to the skin.

Skin is an organs covering the outside of the body, mainly divided into three layers of epidermis, dermis, subcutaneous fat. Such skin acts as a barrier to the body against changes in humidity and temperature, ultraviolet light, and other stimuli of the physical or chemical external environment. Particularly, the epidermis has a function of preventing water evaporation. In order to maintain a constant moisture of the skin, the skin is formed with a sebaceous membrane consisting of sebum secreted from the sebaceous gland and water exuded from the sweat glands. Such a coating plays an important role in preventing water evaporation in the body or skin. However, when the skin is excessively formed, or when chemicals such as dust or color makeup cover the surface of the skin for a long time, the balance of the skin may be broken and the skin may be colored or may cause inflammation such as acne. Therefore, it is necessary to cleanly remove contaminants such as sebum, sweat, dust, chemicals and the like.

Generally, a cleaning agent having excellent cleaning effect is used to completely remove contaminants accumulated on the skin. Such a cleaning agent is mainly composed of a surfactant, an emulsifying agent, a perfume, and the like. Surfactants contain a hydrophilic functional group having affinity to water in a molecule and a lipophilic functional group having affinity with an oily component at the same time so that they are adsorbed on the interface so that the oily component and the aqueous component are mixed well and the contaminants accumulated in the skin Make it washable. However, when a detergent containing a surfactant is used, the skin's useful components and natural moisturizing factor (NMF) are excessively removed, and the pH and osmotic pressure of the skin are lowered. As a result, It may be pruritic, itching, and irritation. In order to recover such damaged skin, it is possible to supply the water loss lost to the skin with skin cosmetics such as skin, essence, and lotion. As an example of such basic cosmetics, Korean Patent Laid-Open Publication No. 2001-0015042 discloses a cosmetic composition containing algae fiber as an active ingredient for moisturizing the skin. However, basic cosmetics can partially supply water to the skin, but the osmotic concentration of the skin still remains low due to insufficient supply of the electrolyte. Also, if this condition persists, the homeostasis of the skin will collapse and the skin will become more sensitive and the ability to defend the material entering from the outside will also be lost. Therefore, a lot of research and development is still required to sufficiently supply useful components such as moisture, moisturizing factors, and the like lost in washing.

Korea Patent Publication No. 2010-0015042

In order to solve the above-mentioned problems, the present invention aims to provide a cosmetic composition capable of supplying a skin with an electrolyte, organic acid and saccharide, which are lost after washing, to maintain healthy skin and a method for supplying a useful ingredient to skin.

An example of the present invention comprises 0.5 to 0.75 parts by weight of an electrolyte, 0.15 to 0.3 parts by weight of an organic acid and 0.05 to 0.15 parts by weight of a saccharide, based on 100 parts by weight of water, wherein the electrolyte comprises 70 to 90% by weight of sodium chloride, 1 to 10% by weight of potassium chloride, and 5 to 10% by weight of sodium bicarbonate, wherein the organic acid comprises at least one member selected from the group consisting of sodium lactate, zinc acetate, and zinc pyrrolidonecarboxylate, Wherein the cosmetic composition has an osmolarity of 250 to 320 mOsm / kgH2O and a pH of 5 to 6. The cosmetic composition of claim ₁ ,

Also, one example of the present invention is a method for cleaning a skin surface, comprising: (a) cleaning the skin surface with a cleaning agent; (b) 0.5 to 0.75 parts by weight of an electrolyte, 0.15 to 0.3 parts by weight of an organic acid, and 00.5 to 0.15 parts by weight of a saccharide, based on 100 parts by weight of water, of the skin surface having water after washing, wherein the electrolyte comprises 70 to 90% , 1-5% by weight of calcium chloride, potassium chloride, 1-10% by weight, a cosmetic composition comprises a sodium bicarbonate 5-10% by weight of osmotic concentration (osmolarity) is 250 to 320 mOsm / kgH ₂ O and a pH of 5 to 6 Applying a cosmetic composition; And (c) rinsing the cosmetic composition after application with water to wipe the skin.

The cosmetic composition according to an embodiment of the present invention provides a moisturizing and soothing effect to the skin by supplying useful components such as electrolytes, organic acids, and saccharides, which have been lost after washing, to restore the skin to its original state. In addition, the cosmetic composition can be wiped off after it is applied to the skin to prevent dehydration of the skin that may occur upon prolonged application, thereby maintaining a healthy skin condition.

Hereinafter, a cosmetic composition according to one embodiment of the present invention and a method for supplying a useful ingredient to skin will be described in detail. It should be understood, however, that such description is illustrative only and is not intended to limit the scope of the present invention.

≪ Cosmetic composition >

An example of the present invention is a cosmetic composition comprising 0.5 to 0.75 parts by weight of an electrolyte, 0.15 to 0.3 parts by weight of an organic acid, and 0.05 to 0.15 parts by weight of a saccharide, based on 100 parts by weight of water,

The skin contains more than 70% of the water, and the other 30% consists of amino acids, saccharides, lipids, minerals and enzymes. Minerals account for less than 5% of the skin, but play an important role in maintaining physiological activity such as skin cell growth and regeneration, intracellular enzyme action, and osmotic pressure control. Therefore, the skin should be provided with an appropriate amount of inorganic material, which may be supplied to the electrolyte and organic acid by the cosmetic composition according to one embodiment of the present invention.

The electrolyte may be selected from the group consisting of Ca, P, K, Na, Cl, Mg, Fe, Iodine, And any one or more ions constituting cells including zinc (Zn), cobalt (Co), manganese (Mn) and the like can be used without limitation. Preferably, at least one selected from the group consisting of sodium, chlorine, calcium, potassium and zinc which can easily control the osmotic pressure of the skin can be used. Such an electrolyte may include at least one selected from the group consisting of sodium chloride, calcium chloride, potassium chloride, and sodium bicarbonate. The electrolyte helps to keep the osmolarity of the cells constant, and sodium plays an important role in regulating the osmotic concentration. If the osmotic pressure is low due to lack of intracellular electrolyte, hypotonic may cause dehydration or accelerate skin aging. If the osmotic pressure is increased due to excessive electrolyte in the cell (hypertonic), there is a large amount of water in the cell The swelling can continue. Therefore, the cell should be supplied with an appropriate amount of electrolyte. The cosmetic composition according to an embodiment of the present invention comprises, in the whole electrolyte, 70 to 90% by weight of sodium chloride; 1 to 5% by weight of calcium chloride; 1 to 10% by weight of potassium chloride; And 5 to 10% by weight sodium bicarbonate. Here, sodium bicarbonate not only supplies sodium to the cells as an electrolyte but also can easily control the acidity of the skin as a pH buffer.

Examples of the organic acid include carboxylic acids such as lactic acid, citric acid, acetic acid, tartaric acid, palmitic acid and oxalic acid. ; Ascorbic acid; Uric acid and the like can be used without limitation as long as they do not show toxicity to cells. Preferably, a carboxylic acid that helps control skin moisturization and acidity while controlling cellular physiological activity may be used. These organic acids include sodium lactate (NaC ₃ H ₅ O ₃ ), zinc acetate (Zn (O ₂ CCH ₃ ) ₂ ) and zinc pyrrolidone-carboxylic acid (C ₁₀ H ₁₂ N ₂ O ₆ Zn) may be included. Preferably sodium lactate and zinc acetate, or may comprise sodium lactate and zinc pyrrolidonecarboxylate. The organic acid includes electrolytes such as sodium and zinc, and the osmolality of the cells can also be controlled. The cosmetic composition according to one embodiment of the present invention comprises 70 to 99.99% by weight of sodium lactate; And 0.0001 to 0.1% by weight of zinc acetate or zinc pyrrolidonecarboxylate.

The saccharide exhibits a moisturizing effect on the skin and can be supplied as an energy source of a cell to help cell growth and regeneration. As the saccharides, monosaccharides and / or disaccharides can be used so that they can be easily absorbed into the skin while allowing the cells to utilize quickly, and they can be used without limitation as long as they do not show toxicity to the cells. These sugars include monosaccharides (C ₆ H ₁₂ O ₆ ) such as glucose, fructose, mannose, and galactose, which are readily available and have excellent moisturizing properties; And disaccharide (C ₁₂ H ₂₂ O ₁₁ ) such as sucrose, lactose, and maltose. Preferably glucose, which is the basic energy source of the cell.

The cosmetic composition according to one embodiment of the present invention comprises 0.5 to 0.75 parts by weight of an electrolyte, 0.15 to 0.3 parts by weight of an organic acid, and 0.05 to 0.15 parts by weight of a saccharide, based on 100 parts by weight of water, By weight.

The natural-derived substance is obtained by isolating an effective ingredient from a natural product, and is an extract of a natural product or a fermented product obtained by fermenting the extract. In particular, naturally derived materials can be obtained from plants known to have no side effects or toxicity. These plants include mistletoe, mulberry, mulberry, mulberry, chamomile, ginkgo leaf, ginseng, ginseng, peppermint, green tea, tea tree leaf. The plant may be extracted by a conventional plant extraction method, and preferably by using water, an organic solvent, or a mixed solvent thereof. For example, ethanol, methanol, glycerin, butylene glycol, and propylene glycol may be used as the organic solvent, and a solvent in which the organic solvent and water are appropriately mixed may be used. Examples of the extraction method using the extraction solvent include hot water extraction, organic solvent extraction and the like. For example, the dried product or the pulverized product of the plants is added to the extraction solvent and stirred at 5 to 40 ° C For 1 to 15 days, or by heating at 40 to 100 DEG C for 4 to 20 hours. Further, the amount of the solvent used for the extraction may be 5 to 20 times the amount of the extraction raw material, based on the weight ratio.

In addition, the cosmetic composition according to an exemplary embodiment of the present invention may further include additives that can be generally used in cosmetic compositions, in addition to the electrolytes, organic acids, and saccharides. Such additives include humectants, emollients, ultraviolet absorbers, preservatives, bactericides, antioxidants, organic and inorganic pigments, perfumes, coolants, and limiters. The additive may be easily selected by those skilled in the art within a range not to impair the objects and effects of the present invention, and the content thereof may be 0.0001 to 5% by weight based on the total weight of the cosmetic composition.

The general cosmetic composition does not contain a pH adjusting agent for controlling the acidity, and therefore the pH varies depending on each constituent component contained in the cosmetic composition, and it is neutral (pH 7) by purified water used mainly as a water for the cosmetic composition. The normal skin has a pH of 5 to 6, and even if a cosmetic composition which is different from the pH of the skin is used, the skin is naturally restored to its original pH because the skin is formed on the surface of the skin. However, when the cosmetic film is excessively removed or the cosmetic film is not formed properly, when the cosmetic composition which is different from the pH of the skin is used, the homeostasis of the skin may be broken due to increase of the acidity, and the skin may become sensitive to small stimulation.

On the other hand, the cosmetic composition according to one embodiment of the present invention has weak acidity including organic acids, and preferably has a pH of 2 to less than 7, more preferably 5 to 6. When the cosmetic composition having a pH similar to that of the skin is used, the skin acidity can be kept constant and the skin can be protected properly.

In addition, the cosmetic composition according to one embodiment of the present invention can contain an electrolyte such as sodium chloride, calcium chloride, potassium chloride, and sodium bicarbonate, thereby maintaining an osmotic pressure concentration such as a healthy skin. Osmotic concentration (osmolarity) of the cosmetic composition may preferably be from 250 to 320 mOsm / kgH ₂ O, may be more preferably 280 to 300 mOsm / kgH ₂ O. When the osmotic pressure range is maintained, the moisture content in the skin can be kept constant so that the skin is moist and elastic, and wrinkles can be prevented from occurring.

The cosmetic composition according to an exemplary embodiment of the present invention may be formulated usually containing an acceptable medium or base, and the cosmetic composition may be provided in all formulations suitable for topical application. Examples thereof include a solution, an emulsion obtained by dispersing an oil phase in an aqueous phase, an emulsion obtained by dispersing an oil phase in water, a suspension, a microemulsion, a microcapsule, a fine granule or an ionic (liposome) , A powder, a paste, a foam or an aerosol composition. More specifically in the form of creams, skins, essences, lotions, powders, ointments, sprays or conical sticks.

As described above, the cosmetic composition according to an embodiment of the present invention including an electrolyte, an organic acid, and a saccharide can be used in a state where water remains on the skin after cleansing or bathing. It keeps the skin always moist and healthy while maintaining homeostasis. In addition, a large amount of sweat discharge can provide sufficient moisture supply and soothing effect for tired skin.

≪ Method for supplying useful ingredients to skin >

The cosmetic composition according to an exemplary embodiment of the present invention provides a useful ingredient that is insufficient in the skin to regulate the acidity and osmotic concentration of the skin and maintain the skin's homeostasis. The cosmetic composition contains a large amount of electrolyte. When the composition is applied to the skin, moisture in the composition of the cosmetic composition evaporates due to the body temperature, so that the conventional osmotic pressure concentration and acidity can be increased. As a result, the intracellular water moves out of the cell and dehydration may occur. In order to solve this problem, it is important to apply the cosmetic composition to the skin and wipe it immediately.

A method for supplying a useful ingredient to skin according to an example of the present invention includes, for example, (a) cleaning a skin surface; (b) 0.5 to 0.75 parts by weight of an electrolyte, 0.15 to 0.3 parts by weight of an organic acid, and 0.05 to 0.15 parts by weight of a saccharide, based on 100 parts by weight of water, wherein the electrolytic solution comprises 70 to 90% by weight of sodium chloride, , 1-5% by weight of calcium chloride, potassium chloride, 1-10% by weight, a cosmetic composition comprises a sodium bicarbonate 5-10% by weight of osmotic concentration (osmolarity) is 250 to 320 mOsm / kgH ₂ O and a pH of 5 to 6 Applying a cosmetic composition; And (c) rinsing the cosmetic composition with water after application.

In the step (a), contaminants such as chemicals are removed by dust, sweat, sebum, and color make-up adhering to the surface of the skin. At this time, cleaning agents such as a cleansing or body soap, a cleansing foam, a cleansing lotion, a cleansing cream, a cleansing oil, and a cleansing tissue can be used without any limitation.

In the step (b), the cosmetic composition according to one embodiment of the present invention is applied in a state where water (moisture) remains on the surface of the skin after washing. The amount of water remaining on the surface of the skin after cleansing is slightly removed by pressing lightly with a towel or toilet paper so that water does not flow down from the face or body. Preferably, 20 to 80% of the water may remain, based on the water present in the skin after washing. When the cosmetic composition is applied to wet skin, it is possible to prevent the moisture contained in the cosmetic composition from rapidly evaporating due to body temperature or the external environment, and the osmotic pressure concentration and acidity of the cosmetic composition applied due to moisture evaporation It is also possible to prevent a rise. On the other hand, the skin after cleansing is in a state in which the skin layer, which is a protective layer, is removed, so that if left for a long time, moisture in the skin may be lost. Therefore, the cosmetic composition is quickly applied. The cosmetic composition is useful as an ingredient of the skin. It contains electrolytes, organic acids and saccharides, and helps to regain a healthy skin condition by calming the irritated skin while supplying a useful ingredient lost by washing.

In the step (c), the cosmetic composition is applied to the skin and then wiped off. When the composition is in the form of a spray, the cosmetic composition may be sprayed directly onto the face or the body, or may be applied to the face or body by sufficiently wetting the cosmetic toilet paper, and in the case of a liquid form You can apply it directly to your face or body by hand or by soaking it on a toilet paper. Water remaining after washing and moisture contained in the cosmetic composition may be evaporated by the body temperature, and the remaining electrolyte and organic acid may be present on the skin coated with the cosmetic composition. If the electrolytes and organic acids remain on the surface of the skin for a long time, the water in the skin may be moved out of the skin to cause dehydration of the skin. To prevent the cosmetic composition from remaining on the skin for a long time, I wipe it out. At this time, the cosmetic composition can be wiped after it is applied to the skin, or can be wiped after it is absorbed by tapping with a hand. When the cosmetic composition is wiped off, a cosmetic toilet paper or a towel such as a toilet paper or a toilet paper may be used to minimize irritation of the skin, or the water remaining on the skin may be removed with a toilet paper or a towel after lightly rinsed with water.

As described above, when the cosmetic composition according to one embodiment of the present invention is used, it is possible to maintain the homeostasis, such as the pH and osmotic pressure of the skin, while supplying a useful ingredient lost by washing to the skin, .
