Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lip cosmetic composition containing reversed micelles,

The present invention relates to a liposome comprising a water-soluble component in a reverse micelle using a reverse micelle, wherein the hydrophilic substance is transparently solubilized in an oil phase, and adding to the lipstick composed of an oil-soluble component, thereby increasing the moisturizing effect of the lip and reducing the generation of wrinkles, To a lip cosmetic composition.

Lipstick, which is a lip cosmetic, is intended to keep the lips soft and moist by increasing the lip protection, especially the lip moisturization. It is mainly used for various nutritional ingredients, organic and inorganic substances useful in skin such as vegetable wax, ester oil, It is made of a uniform mixture in which a non-aqueous inorganic pigment is dispersed. Moisture lipstick using a general oil-based agent is widely used in waxes, pigments dispersants, oil-based emollients, coupling agents for improving the compatibility of waxes and oils, pigments, preservatives, fragrances, and additives for rod- It has a moisturizing effect that prevents oil evaporation by forming an oil film on the lips rather than supplying moisture to the lips. In order to provide a lipstick that gives a more aggressive moisturizing effect, a water-in-oil (W / O) emulsified lipstick containing water or a hydrophilic polyhydric alcohol using a surfactant has been attempted. The lipstick provided by the water-in-oil type emulsion emulsion has a moisturizing effect by moisture, so that the lip is not dried after being applied and is kept moist, and the feeling of use such as spreadability, smoothness, and feel is excellent.

In addition, glycerin, propylene glycol, water and the like are added to lipstick as a water-based (W / O) type emulsifying base using various emulsifiers in order to improve the stability and moisturizing property. Have been introduced, but problems such as evaporation of water and discoloration of color may occur during manufacturing.

Solubilization or inverse solubilization phenomenon in a method containing a water-soluble component means that a surfactant that exhibits a solubilizing effect as a phenomenon in which a substance insoluble or poorly soluble in a solvent dissolves in an aqueous solution or an oil solution of the surfactant is referred to as a solubilizer A solubilized liquid or solid is called a freestanding cargo. Often, solubilization is a phenomenon in which an oily component dissolves in an aqueous solution of a surfactant, and a phenomenon in which an aqueous component dissolves in a surfactant oil solution is called reverse solubilization. These solubilization techniques are widely applied in many industries such as pharmaceuticals, cosmetics, and food.

The solubilization phenomenon plays an important role in the micelle of the surfactant. The solubilization phenomenon largely depends on the solubilization position of the micelle. First, non-polar materials such as hydrocarbons dissolve in the micelles. Second, substances such as higher alcohols and fatty acids, which share polar and non-polar groups in the molecules, are solubilized in the inner and hydrophobic chains of the micelles. Third, The hydrophilic substance is solubilized in the hydrophilic group of the reversed micelle and the fourth is the hydrophilic molecule such as the polyhydric alcohol or the water soluble dye is adsorbed on the surface of the micelle.

When moisturizing ingredients are used in lip products, there are some parts which adversely affect the product due to the characteristics of raw materials contained in them for the purpose of moisturizing. For example, the compatibility of the lipstick components is significantly lowered, and the oil is separated from the lipstick to make the appearance of the stick dirty. The addition of the water-soluble component lowers the hardness of the stick, And the risk of skin irritation due to emulsifiers. In addition to this, the gloss of the appearance due to the volatilization of water due to aging, the cohesion of the hydrophilic inorganic pigment used in the lipstick, and the change of the color tone cause a drop in the product value, Problems have been raised, and in addition, the content of water-soluble components for moisturizing purposes added to lipsticks has been limited due to a lack of substantial emulsifying techniques.

The present invention relates to a method for preparing reverse micelles by appropriately combining surfactants and cosurfactants and a method for stably incorporating water-soluble components in reverse micelles, wherein the reverse micelles form nanoparticles and are thermodynamically stable. The present invention relates to a new lip cosmetic composition for improving the function of lips by increasing the moisturizing effect of lip and reducing the generation of wrinkles by adding the water-soluble component-containing reverse micelles to the lipstick composed of oil-soluble ingredients.

The present invention relates to a method for preparing reverse micelles in which hydrophilic substances are dispersed finely and stably in an oil phase, and a method for stably incorporating water-soluble components in reverse micelles to lipstick, whereby the hardness of the stick is not lowered, It does not change appearance gloss due to the volatilization of water, absorbs moisture that is evaporated from the lips without falling in product value due to cohesion of hydrophilic inorganic pigments used in lipstick, change of color tone, etc. and supplies moisture in reverse micelle, And the function of the lips can be improved by reducing the generation of wrinkles.

The nanoparticle manufacturing method is a nanoparticle manufacturing method using a supramolecular microstructure surfactant molecular self-assembly system.

Surfactants, which are the most representative amphipathic substances, have a certain order due to the interaction between hydrophilic-hydrophobic groups in the molecule in an aqueous solution or a solvent, and can form thermodynamically stable colloidal supramolecular assemblies. For example, a monolayer, a doublelayer, a micelle, a reverse micelle, a microemulsion, a liquid crystal, a liposome or the like depending on the kind of the surfactant and the manufacturing technique. And the like can be obtained. In particular, a nanomaterial preparation method using a microemulsion is known as a method capable of easily producing fine particles having a relatively uniform distribution.

The microemulsion is characterized by being thermodynamically stable, which means that when the microemulsion is formed, the Gibbs free energy has a negative value (DELTA G < 0) compared to the separated state. As a result, the microemulsion is formed spontaneously and phase separation does not occur under the condition that there is no change in temperature or the like. The particle size of the dispersed phase is very small as 5 to 140 nm and thus appears to be apparently transparent or translucent. When the particle size is small, the area of the interface is very large and the interfacial tension is small, so that the microemulsion is spontaneously formed unlike the macroemulsion. As a result, the amount of energy required to make the emulsion is small, thereby reducing the actual production cost. Usually, when preparing the macro-emulsion, various factors such as device, ingredient, mixing strength and time, emulsification time, temperature, mixing order of additives, heating / cooling rate and heat loss should be considered. The production cost will be greatly reduced.

Thus, in the present invention, a reverse micelle is prepared by combining a surfactant and an auxiliary surfactant, and a method for encapsulating a water-soluble component in the reverse micelle is developed. The thus-prepared reverse micelles containing water-soluble components are added to lipsticks Thereby increasing the moisturizing effect of the lips and reducing the generation of wrinkles, thereby improving the function of the lips.

According to a preferred embodiment of the present invention, there is provided a method for producing an oil-in-water emulsion, comprising: 1) dissolving a surfactant in an oil to prepare an oily phase solution; 2) preparing an oily phase by adding an auxiliary surfactant to the oily phase solution; 3) preparing a reversed micelle by adding a water-soluble component to an oily solution; 4) a step of preparing a lip cosmetic composition containing reverse micelles, and a reverse cosmetic composition containing a water-soluble component can be prepared, and a lip cosmetic composition containing such reverse micelles can also be prepared.
