Description

A cosmetic composition for improving skin sagging

The present invention relates to a lifting cosmetic composition that improves skin sagging by pulling sagging skin, and more particularly, a composition of a pack formulation to be applied to the skin, wherein the gelling component contained in the composition is applied to the skin and air when applied to the skin. The present invention relates to a cosmetic composition for improving skin sagging having a lifting effect by hardening by contact with and causing shrinkage.

In general, the goal of cosmetics is to keep skin clean and beautiful, to maintain healthy skin, and to delay or prevent skin aging that occurs physiologically with age.

As the skin ages, the lipid composition and content of the lipid layer, which has the function of the skin barrier, changes rapidly, and its function decreases rapidly, leading to a decrease in moisture content of the skin, drying of the skin, and causing various skin lesions. In addition, the increase in the amount of ultraviolet rays due to environmental pollution, air pollution and excessive fatigue and stress of modern people produce less reactive reactive oxygen, free radicals and peroxides, and the skin is affected by them, resulting in biological components (proteins, nucleic acids, Cell membrane lipids) are oxidized or denatured, which is a major cause of skin aging. In particular, collagen, elastin, and the like, which form the skin connective tissue, are oxidized and lose their function. As a result, the skin loses its elasticity and the wrinkles of the skin are excessively formed.

The skin aging phenomenon such as sagging skin, loss of elasticity and wrinkle formation is caused by inhomogeneity of cells, loss of elastin, destruction of collagen, reduction and delay of collagen synthesis. After all, skin aging occurs in the skin epidermis, but rather in the dermis.

The general lifting cosmetics for improving skin aging such as sagging, loss of elasticity, etc. are using a patch formulation utilizing a curing phenomenon of the polymer. It is usually applied to cosmetics on the finished patch, which can not be expected to lift the skin due to the patch itself, as well as adhesives used for the adhesion of patches and cosmetics or cosmetics and skin. Due to the components, skin irritation and trouble occurred.

Accordingly, the present invention has been proposed to solve the above problems, a lifting agent comprising a first agent containing a common skin improvement component widely used in cosmetics and a second agent comprising an alkali silicate salt and a gelling component It is an object of the present invention to provide a cosmetic composition for improving the skin sagging to obtain a skin lifting effect while minimizing the problem of skin irritation due to the adhesive component by mixing to the skin.

In order to achieve the above object, the present invention comprises a first agent containing a conventional skin improvement component; And a second agent comprising a gelling component based on alkali silicate salts.

More specifically, in the cosmetics of the present invention, the first agent includes a skin improvement ingredient, a thickener, an antibacterial agent, and water that gives a skin improvement effect such as skin elasticity, pore reduction, whitening, skin regeneration, lipolysis, and wrinkle improvement. Doing. Therefore, the first agent is different in the overall skin improvement function of the cosmetic according to the type of skin improvement ingredients to be selected, and includes a thickening agent to increase the ease of use and antimicrobial agent to increase the ease of use by preventing the flow of cosmetic when applied to the skin. Doing.

On the other hand, in the cosmetic of the present invention, the second agent includes an alkali silicate salt, a pH adjuster, an antibacterial agent, and water, among which alkali silicate salts are gelling components that form a silicate gel when applied to the skin to form a gel. At the same time, it corresponds to a component that gives a skin lifting, ie, lifting effect by exhibiting a contraction effect, and a pH adjuster uses an alkaline substance as a component to help dissolution of alkali silicate salts.

In addition, when the germanium component is additionally mixed in the second agent, the skin improvement component contained in the first agent can be penetrated deeper into the skin, thereby providing an excellent skin improvement effect.

The cosmetic composition according to the present invention, unlike the conventional formulation of the patch-type cosmetics, the gelling component of the alkali silicate salt is used in contact with the skin and air, and rapidly cures naturally over time, using a skin improvement component It is used as a method of applying to the skin after mixing the first agent and the second agent to form a silicate gel to give a lifting effect.

That is, the cosmetic composition for improving the skin sagging of the present invention is formed to give a skin pulling effect of the formulation itself by forming a silicate gel on the surface of the skin and applying a shrinkage effect at the same time after applying to the skin. Therefore, the present invention is not only easy to use in the form applied to the skin as in general cosmetics, and unlike the general patch formulation, it does not use an adhesive ingredient for fixing the cosmetic ingredient to the support, thereby increasing the stability to the skin. . In addition, by using a combination of conventional skin elasticity aids, anti-wrinkle agent, etc. to obtain a skin improvement effect, by naturally curing over time after application on the skin, strong skin pulling effect, convergence effect and pore contraction effect At the same time to provide, and to be washed with water to implement a simple to remove.

As described above, the cosmetic composition of the present invention is easy to use because it is in the form of applying to the skin as a general cosmetic, and unlike the general patch formulations do not use adhesives on the skin to increase the stability to the skin and the formulation itself It can give a natural strong skin pulling, ie lifting effect. In particular, after being dried on the surface of the skin, it is a simple washable pack that can be easily removed by washing with water, but has a very strong lifting effect.

In addition, the cosmetic composition of the present invention is capable of directly blending raw materials having functional effects such as skin elasticity aids, wrinkle improving agents, whitening agents, and skin regenerating agents, and enhancing delivery effects, thereby enabling the development of new types of functional cosmetics. There is an advantage.

The cosmetic of the present invention comprises a first agent containing a skin improvement ingredient, a thickener, an antibacterial agent and water, and a second agent containing an alkali silicate salt, a pH adjuster, an antibacterial agent and water.

First, the skin improvement component of the first agent is a conventionally known component, beta glucan, lactoglobulin, AHA (a-hydroxy acid), etc. as a skin elasticity component, arbutin, vitamin E, diphospho as a whitening component Glycerate (Diphosphoglycerate; DPG) as a skin regeneration ingredient, Cooper Tripeptide, Acetyl hexapeptide, Epidermal Growth Factor (EGF, Epideral Growth Factor), Vitamin-A, Pine Fruit Extract Green liquor extract, caffeine, Green No. 8, an herb extract, and adenosine, collagen, elastin, hyaluronic acid, vitamin C, dipalmitoyl hydroxyproline (DPDH) And the like, and any of the above ingredients may be used as long as it is cosmetically acceptable and does not make it difficult to exhibit the strong lifting effect of the present invention. All.

In addition, the thickener increases the viscosity of the liquid cosmetic composition and serves to prevent it from flowing down during application to the skin prior to the formation of the silicate gel. In the present invention, carbomer, xanthan gum, and cellulose gum that have less skin irritation are used, and among them, it is most preferable to use carbomer in terms of application and feeling after washing. Do.

The antimicrobial agent is a component for improving the preservation of the cosmetic composition, and may be used imidazolidinyl urea, parabens and the like used as an antimicrobial preservative of a conventional cosmetic.

In the first formulation of the cosmetic composition of the present invention, if the mixing amount of the skin improvement component is too large, the cost is increased and if the mixing amount is too small, the skin improvement effect is lowered. Due to the difficulty in application, too small amount of antimicrobial agent can reduce the preservation and give too much skin irritation. To 100 parts by weight of purified water, 0.1 to 5 parts by weight of thickener, 0.01 to 2 parts by weight of antimicrobial agent, skin improvement ingredients It is preferable to contain 0.1-10 weight part.

On the other hand, the second agent of the cosmetic of the present invention contains an alkali silicate salt as a gel forming agent, the alkali silicate salt is (X _n O) _m · (SiO ₂ ) of the chemical formula (where n = 1 ~ 2, m = 2 to 4, X is an element of one of Na, K, Mg, Ca, and Sr). In the present invention, an alkali silicate salt in an aqueous solution is used for convenience. The alkali silicate salt is present in a stable solution in a strong alkali state of pH 9 or higher, and when applied to the skin, the area of contact with air becomes very large. Absorption of carbon dioxide in the air quickly lowers the pH, and at the same time the pH is lowered by the reaction with weakly acidic skin, the pH is lowered to form a silicate gel. At this time, the silicate gel formed is strongly adhered to the skin and at the same time causes a contraction action, thereby exhibiting a lifting effect on the skin.

In the present invention, any type of the substance having the above formula may be used as the alkali silicate salt, but a water glass such as liquid sodium silicate or liquid potassium silicate, which is widely available commercially and readily available, and is easy to prepare a liquid preparation. Most preferably. The liquid sodium silicate is represented by the molecular formula of Na ₂ O-nSiO ₂ -xH ₂ O, which is commercially sold as No. 1, No. 2, No. 3 and No. 4 according to the ratio of the silicic acid component and the sodium oxide component. Generally, the most widely used is water glass 3, which refers to liquid sodium silicate containing Na ₂ O 9-10 wt% and SiO ₂ 28-30 wt%, and in the embodiment of the present invention, water glass 3 is used as sodium silicate. It was.

In addition, in the present invention, a liquid solution of sodium silicate or potassium silicate, that is, water glass, is mixed with a strongly alkaline solution containing purified water and a pH adjuster to prepare a second preparation composition to maintain a stable solution state. In this case, the pH adjusting agent is a substance capable of inducing the second agent composition to be alkaline, and in the present invention, sodium hydroxide or potassium hydroxide is mixed as the pH adjusting agent, and when the pH is too high, it irritates the skin and requires careful handling. If the pH is too low, the silicate may precipitate, so adjust the pH so that it is in the range of pH9-13.

In the second agent, an antimicrobial agent is included in order to increase the preservation, and there is no particular limitation as long as it is a conventional antimicrobial preservative used in cosmetics, and examples thereof include methyl parabens with low skin irritation.

In the second formulation of the cosmetic composition of the present invention, when the mixing ratio of sodium silicate or potassium silicate is too high or too low, the gel formation rate is too fast or slow, so that the convenience of skin coating may be reduced or the lifting effect may be deteriorated. If the mixing ratio of sodium or potassium hydroxide is too high or too low, it may irritate the skin or the silicate gel may be formed before the application of the skin.In the case of antimicrobial agents, if the mixing ratio is too high, it may irritate the skin and if it is too low, the preservation will be inferior. Can be. Therefore, in this invention, the 2nd preparation containing 0.01-10 weight part of sodium hydroxide or potassium hydroxide, 5-70 weight part of sodium silicates or potassium silicate, and 0.01-2 weight part of antibacterial agents is used with respect to 100 weight part of purified water.

In addition, germanium powder may be added to the second agent of the present invention. Germanium is a substance that emits far-infrared rays, and it promotes blood circulation and waste products through the thermal action and helps to absorb cosmetic ingredients. In the present invention, a high solubility in water and safe to use organic germanium (GeCH ₂ CH ₂ COOH) ₂ O ₃ in powder form widely used for food and medicine, the amount is too small, the effect is too low, too much cost As it rises, it uses within the range of 0.1-1 weight part with respect to 100 weight part of purified water.

As a method for using the skin sagging cosmetic composition of the present invention, the first agent and the second agent may be formulated in a premixed state or may be separately formulated and mixed before application to the skin. When the first agent and the second agent are mixed and commercialized, alkali silicate salts contained in the second agent are combined with various skin improving ingredients of the first agent or absorb carbon dioxide in the air to gradually cure, thereby increasing viscosity. According to the experiments of the present inventors, the viscosity of the product generally increases within a few days, making it difficult to use. For this reason, if the formulation of the first agent and the second agent is pre-mixed, the service life of the product is considerably limited, and the use of a completely airtight container can extend the shelf life of the product, but the cost of the container is also high. There is a disadvantage.

Therefore, the cosmetic composition of the present invention is preferably used as a method of applying to the skin after mixing the first formulation and the second formulation separately formulated, in which case too much gel formation rate is too high Since it may be fast or slow and may not be suitable for showing a lifting effect or may be inconvenient to be applied to the skin, it is preferable to mix 15 to 20 parts by weight of the second agent with respect to 100 parts by weight of the first agent.

Hereinafter, the present invention will be described in more detail through Examples, Comparative Examples, and Experimental Examples. However, these Examples, Comparative Examples, and Experimental Examples are only for better understanding of the present invention, and the scope of the present invention is not limited to the following Examples and Experimental Examples.
