Description

Spray emulsion type cosmetic composition and its manufacturing method {COSMETIC COMPOSITION OF EMULSION TYPE FOR SPRAY APPLICATION AND MANUFACTURING METHOD OF THE SAME}

The present invention relates to an emulsion-type cosmetic composition for spraying and a method of manufacturing the same, and more particularly, it is possible to evenly spray the skin like a general liquid mist, but there is no flow of liquid components and rather, it naturally forms an oil film on the skin to moisturize. The present invention relates to an emulsion-type cosmetic composition for spraying that can be maintained for a long time and a method for producing the same.

Unlike in the past, where rich and nutritious lotion was preferred, consumers now prefer to use lotion that has moderate moisturizing and nutritious feelings, but has a refreshing feeling of use and convenient usage. Accordingly, there is a trend of increasing the number of products of a mist type or a simple spraying method such as an aerosol.

However, since the spraying type is not easy to use because the spraying angle is narrow when the viscosity of the contents is high, the contents are generally limited to a liquid form with little viscosity, and the contents flow down from the skin accordingly. I did.

In order to solve this problem, a gel-type spraying product using a gelling agent such as gellan gum has been developed. Gellan gum is a heteropolysaccharide obtained by purifying, drying and pulverizing a high molecular polysaccharide obtained by pure culture and fermentation of microorganisms on carbohydrates with isopropyl alcohol. The heteropolysaccharide is composed of rhamnose, glucuronic acid and glucose 1:1:2, and the glucuronic acid is neutralized by mixing potassium, sodium, calcium, and magnesium salts. Gellan gum is an off-white powder, soluble in hot or cold deionized water, forms a gel even in small amounts, and has high stability against heat and pH, so it has good applicability.

When gellan gum is dispersed and hydrated in water at high temperature and then cooled without separate physical stress, a strong gel is formed, but when a shear force is applied during cooling, the bond inside the gel is weakened. Is formed, and the viscosity of this weak gel is very low even when only a small force is applied from the outside, so that it has a liquid-like fluidity. This fluid gel has a dispersing ability without increasing the viscosity. That is, by appropriately controlling these fluid properties of gellan gum, it is possible to develop a cosmetic composition for spraying that does not flow down by maintaining the shape of the spraying paper gel while spraying from the spraying container.

However, gel-type cosmetics using the properties of gellan gum are not only difficult to uniformly spray the ingredients when spraying because the formulation is lumpy, and there is a limit to maintaining sufficient moisturizing power on the skin. As it evaporates, the skin feels more dry. Accordingly, there is a need to develop a cosmetic composition that allows even spraying and forms a thin oil film on the skin to maintain moisture for a long time while allowing free spraying using a sprayer.

Republic of Korea Patent Publication No. 10-2012-0058917

The present invention is to solve the above problems, and it is possible to spray evenly using a spray container, and there is no flow when spraying, and furthermore, an oil film can be formed on the skin, so that the moisturizing power is maintained for a long time and a refreshing feeling of use. It is to provide an emulsion-type cosmetic composition for spraying.

The above and other objects and advantages of the present invention will become apparent from the following description of preferred embodiments.

In order to achieve the above object, the present invention uses a spray containing 0.1 to 0.5 parts by weight of gellan gum, 0.01 to 0.05 parts by weight of calcium lactate, 0.1 to 3 parts by weight of emulsifier and 1 to 5 parts by weight of oil based on the total weight of the composition. It provides an emulsion type cosmetic composition.

In this case, the oil preferably includes 20 to 80 parts by weight of caprylic/capric triglyceride and 20 to 80 parts by weight of squalene.

In addition, the emulsifier preferably contains 30 to 50 parts by weight of olive emulsified wax (Cetearyl Olivate), 30 to 50 parts by weight of Glyceryl Stearate, and 10 to 30 parts by weight of Polyoxyethylene Sorbitan Monooleate. Do.

On the other hand, the cosmetic composition of the present invention comprises the steps of dissolving gellan gum in purified water at 75 to 80°C, preparing an emulsion by adding oil and emulsifier to purified water at 75 to 80°C in which the gellan gum is dissolved, the 75 to 80 Through the steps of adding calcium lactate to the emulsion at °C, cooling the emulsion to which calcium lactate is added to 35 to 45 °C, and adding a moisturizing agent and natural extract to the cooled emulsion at 35 to 45 °C. Can be manufactured.

The emulsion-type cosmetic composition according to the present invention can be sprayed evenly, even when applied to a spray-type container, as in a general liquid type, and does not flow down when spraying the skin. In addition, even with a small amount, a thin oil film is evenly formed on the skin, so that if the moisturizing power is maintained for a long time, there is no stickiness and a refreshing feeling of use.

However, the effects of the present invention are not limited to the above-mentioned effects, and other effects not mentioned will be clearly understood by those skilled in the art from the following description.

Hereinafter, the present invention will be described in detail with reference to embodiments of the present invention and drawings. These examples are only illustratively presented to explain the present invention in more detail, and it will be apparent to those of ordinary skill in the art that the scope of the present invention is not limited by these examples. .

In addition, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs, and in case of conflict, the present specification including definitions The description of will take precedence.

The cosmetic composition according to an embodiment of the present invention includes 0.1 to 0.5 parts by weight of gellan gum, 0.01 to 0.05 parts by weight of calcium lactate, 0.1 to 3 parts by weight of emulsifier, and 1 to 5 parts by weight of oil based on the total weight of the composition. It is characterized by, and may contain additional water and functional additives such as moisturizers and natural extracts.

The cosmetic composition is a step of dissolving gellan gum in purified water at 75 to 80°C, preparing an emulsion by adding oil and an emulsifier to purified water at 75 to 80°C in which the gellan gum is dissolved, and in the emulsion at 75 to 80°C. It can be prepared by adding calcium lactate, cooling the emulsion to which calcium lactate is added to 35 to 45°C, and adding a moisturizing agent and natural extract to the cooled emulsion at 35 to 45°C. . Hereinafter, each step and component will be described in detail.

First, gellan gum is dissolved in purified water at 75~80℃ to prevent the cosmetic from flowing down when spraying the skin and to have an appropriate viscosity. Gellan gum is preferably used in an amount of 0.1 to 0.5 parts by weight based on the total weight of the composition, and if it is less than this, the cosmetic may flow down when spraying the skin, and if it is more than this, the viscosity of the cosmetic may be too high and spraying may be difficult. At this time, the purified water can be replaced with various functional aqueous solutions such as gorsoana sap if it is suitable for dissolving gellan gum.

When the gellan gum is sufficiently dissolved, oil and emulsifier are added and mixed at a temperature of 75 to 80°C to prepare an emulsion. The oil is for forming a thin oil film on the skin when spraying the cosmetic, and it is preferable to use 1 to 5 parts by weight based on the total weight of the composition, and if it is less than this, it is difficult to form an oil film on the skin. Not only does it not work, and when applied to the skin, the feeling of refreshing application may decrease.

When the oil is applied to a sprayer, an oil that can be sprayed at a wide spray angle should be used, preferably caprylic/capric triglyceride 20 to 80 parts by weight and squalene based on the total weight of the oil. It is preferable to use 20 to 80 parts by weight of (squalene).

The caprylic/capric triglyceride is oil derived from palm oil and coconut, and has a structure similar to human sebum, and squalene is oil derived from shark liver and olive, and both oil components are applied to a general spray container and sprayed. It is possible to spray evenly with a wide spray angle rather than a straight line.

The emulsifier not only plays a role to disperse the oil component well in the cosmetic composition, but also acts together with the oil component by itself to give the skin a feeling of moisture and maintain moisturizing power. The emulsifier is preferably used in an amount of 0.1 to 3 parts by weight based on the total weight of the composition, and if it is less than this, the oil component is difficult to properly disperse in the cosmetic. It can cause trouble, etc.

In addition, when the emulsifier is applied to a sprayer, an emulsifier capable of spraying at a wide spray angle should be used, preferably 30 to 50 parts by weight of olive emulsified wax (Cetearyl Olivate), and glyceryl stearate based on the total weight of the emulsifier. Stearate) 30 to 50 parts by weight and polyoxyethylene Sorbitan Monooleate 80 (Polyoxyethylene Sorbitan Monooleate) 10 to 30 parts by weight are preferably used.

The olive emulsified wax is not only sprayable, but is also a natural emulsifier that minimizes irritation to the skin and improves moisturizing power when applied to the skin, thereby improving a feeling of moisture and a feeling of use. The glyceryl stearate and polysorbate 80 are generally widely used emulsifiers and can also be sprayed widely and evenly. Although it is possible to form and spray an emulsion with only glyceryl stearate and polysorbate 80, it is preferable to be used with olive emulsified wax because the feeling of use is poor when applied to the skin.

When the emulsion is completed, calcium lactate is added at a temperature of 75 to 80°C. Calcium lactate is used together with gellan gum to control the viscosity and strength of the gel. As the amount added increases, the viscosity and strength of the gel increases, and the gelation point and melting point also increase.

In the case of a general mist-type cosmetic, about 0.1 to 10 parts by weight of a metal salt such as calcium lactate is added, and the gel formed after cooling is pulverized through a homergenizer, etc. The present invention is an emulsion type of oil and emulsifier. Since a certain degree of viscosity is secured from the ingredients, calcium lactate can maintain a viscosity that does not flow off the skin even if only a small amount of 0.01 to 0.05 parts by weight is used. In addition, since only a small amount of calcium lactate is used, there is no need to go through a separate grinding process through a homergenizer or the like after cooling.

The emulsion added to calcium lactate is cooled to 35-45° C. to form a fluid gel, and there is no need to go through a separate pulverization process, so that a moisturizing agent and natural extract are finally added and mixed. The moisturizing agent may include a variety of commonly used moisturizing ingredients such as glycerin, butylene glycol, and propanediol, and the content is preferably used in an amount of 10 to 45 parts by weight based on the total weight of the composition.

On the other hand, the moisturizing agent preferably contains a polyethylene glycol compound containing oxyethylene oxygen capable of hydrogen bonding with hydrogen among the hydroxyl groups of water in order to increase the spray angle of the cosmetic. When hydrogen among the hydroxyl groups of water and oxyethylene oxygen of a polyethylene glycol compound form a hydrogen bond, the hydrogen bond acidity of water is weakened, and unlike the case where only water is present, structural deformation occurs and the cohesive power of water is reduced accordingly, and the time of spraying from a spray. The square can be widened.

In addition, the higher the molecular weight of the polyethylene glycol compound, the greater the absolute number of oxyethylene oxygen capable of achieving hydrogen bonding, so the use of a higher molecular weight polyethylene glycol compound can widen the spray angle of skin cosmetics. However, since the number of hydrogen and the number of oxyethylene oxygen in the polyethylene glycol compound among the hydroxyl groups of water that can achieve hydrogen bonding strength are limited, saturation occurs above a certain amount and the injection angle cannot be improved any more. Accordingly, the molecular weight of the polyethylene glycol compound is preferably 200 to 1100.

As a polyethylene glycol compound moisturizing agent capable of widening the spray angle, preferably, polyethylene glycol/polypropylene glycol-17/6 copolymer, polyethylene glycol/polypropylene glycol/polybutylene glycol-8/5/3 glycerin and glycerin One or more selected from the group consisting of Glycereth-26 may be used.

The content of the polyethylene glycol is preferably 5 to 15 parts by weight based on the total composition, and in order to further widen the spray angle of the cosmetic and further enhance the feeling of use, a polyol compound or polydiethoxyethyl succinate as an additional moisturizer component succinate). The polyol compound may be one or more selected from the group consisting of butylene glycol, propylene glycol, dipropylene glycol, glycerin and propanediol, and the molecular weight is preferably 75 to 140.

On the other hand, the natural extract may be a variety of functional extracts extracted from natural substances can be used, for example, black ginger extract, sprout extract, chrysanthemum flower extract, cypress tree leaf extract, pomegranate extract, sewage extract, black sesame extract having a whitening or moisturizing effect. Extract, peony extract, peony root extract, phalanx blood extract, ringworm extract, gold and silver flower extract, angelica extract, branch pupa extract, japonica extract, broiler extract licorice extract, bokryeong extract, baekchul extract, Yeongyo extract, ginseng extract, tangerine peel extract Various natural extracts such as extracts can be used.

When extracting the active ingredient from the natural product, hot water extraction is generally used. In order to more efficiently extract various functional ingredients, it is preferable to use alkaline ionized water as a solvent to extract the active ingredients from the natural product. Alkaline ionized water has a smaller molecular group than water, so it has good penetrating power, high heat conduction, and strong dissolving power, so that component elution is efficiently carried out even at low temperatures.

In general, when extracting natural products, it is common to use purified water or a solvent in which a certain amount of purified water and alcohols are mixed, and extract at 90 to 100°C. However, with such an extraction method, components weak to heat are practically easily decomposed during the extraction process.

However, by using alkaline ionized water as a solvent, the active ingredients of natural substances are safely extracted at a relatively low temperature of 70 to 80°C, so that the extract's original antibacterial function can be sufficiently exhibited, and the absorption power and dissolution power are excellent.

In addition, by adding 1 to 30% by weight of glycerin to the extraction solvent, an osmotic pressure phenomenon between the solute and the solvent may be applied, so that the elution of the active ingredient can be made better. At this time, in order to improve the functionality of the extracted natural extract and solve odor problems, 0.1 to 70 g of calcium oxide was added and stirred based on 100 ml of the filtrate extracted using the alkaline ionized water as a solvent, and then 4 to 15 The process of filtering the supernatant by allowing it to stand at °C for 12 to 24 hours may be additionally performed.

When the natural extract is treated with calcium oxide, the color becomes transparent and odor is removed, and the functionality can be improved by treating foreign substances.

Hereinafter, the configuration of the present invention and effects thereof will be described in more detail through specific examples and comparative examples. However, the present examples are for explaining the present invention in more detail, and the scope of the present invention is not limited to these examples.

[Example]

Examples were prepared as follows with the composition of Table 1 below. After dissolving gellan gum in purified water at 80° C., oil and emulsifier were added to purified water in which gellan gum was dissolved, followed by mixing to prepare an emulsion. After adding and mixing calcium lactate to the prepared emulsion, the mixture was cooled to 40°C, and a moisturizing agent and natural extract components were added and mixed to prepare an emulsion-type cosmetic composition.

[Comparative Example]

A comparative example was prepared as follows with the composition of Table 2 below. In Comparative Example 1, after dissolving gellan gum and calcium lactate in purified water at 80°C, the gel formed by cooling to 40°C was pulverized at 3000 rpm using a homogenizer. A gel-type cosmetic composition was prepared by adding and mixing a moisturizing agent component and a natural extract to the pulverized gel.

In Comparative Examples 2 to 3, cosmetic compositions were prepared in the same manner as in Examples, but emulsion-type cosmetic compositions were prepared by using other oil components that are commonly used in cosmetics.

[Experimental Example]

Each of the above Examples 1 to 3 and Comparative Examples 1 to 3 was prepared, filled in a mist container, and tested on 20 male/female subjects in their 20s to 30s. After washing the face, the sample was sprayed on the tester's cheek-maxilla and left for 30 seconds to observe the degree of dripping, and then rubbed for 1 minute to conduct a sensory test for the feeling of use, and the dripping and feeling of use were determined. In addition, the viscosity of each cosmetic was measured and the results are shown in Table 3 below.

(5 points: very good (even spraying, no dripping, no stickiness), 4 points good, 3 points: normal, 2 points: poor, 1 point: very poor)

As can be seen from Table 3, in the case of the embodiment of the present invention, there was no flow, and a thin oil film was formed on the skin when spraying, so that the feeling of use was excellent because the moisture feeling was high and the stickiness was low. On the other hand, the gel-type cosmetic of Comparative Example 1 was difficult to spray evenly due to its lumpy formulation, and there was a limitation in that it was difficult to evenly spray the moisture and the ingredients were quickly evaporated and maintained for a long time, and the cosmetics of Comparative Examples 2 and 3 had a high viscosity, so spraying was difficult. The feeling of moisture also fell due to the strong stickiness.

In order to examine the above characteristics in more detail, the finished formulation of the cosmetic composition of Example 1 (left) and Comparative Example 1 (right) was compared in FIG. 1. As can be seen from the drawings, it can be seen that Comparative Example 1 is a lumpy formulation that is difficult to even spray, whereas Example 1 is a homogeneous emulsion formulation.

Meanwhile, FIG. 2 is a comparative photograph showing the degree of spreading when the cosmetic compositions of Example 1 (top), Comparative Example 1 (bottom), and Comparative Example 3 (middle) of the present invention are dropped on paper. As can be seen from the drawings, in the case of Comparative Example 2, the viscosity is too high, so it can be expected that spraying itself is difficult and even spreading is difficult.

3A and 3B are photographs showing the spraying angle of the cosmetic composition of Example 1 of the present invention and the degree of spreading of the sprayed cosmetic, and it can be seen that the spraying angle is wide and even spraying is performed. On the other hand, Figures 4a and b are photographs showing the spray angle of the cosmetic composition of Comparative Example 2 of the present invention and the degree of spread of the sprayed cosmetic, and it can be seen that the water gun spray is performed and the spray liquid is also aggregated and sprayed without spreading evenly. .

In the present specification, only a few examples of various embodiments performed by the present inventors are described, but the technical spirit of the present invention is not limited thereto or is not limited thereto, and may be modified and variously implemented by those skilled in the art.
