Abstract

The present invention relates to a two-layered high moisturizing cosmetic composition containing a capsule, and a method for producing the same. More specifically, the present invention relates to a two-layered high moisturizing cosmetic composition containing a capsule, which includes 0.1 to 15.0 wt% of polyol, 0.1 to 0.5 wt% of an increasing agent, 0.1 to 10.0 wt% of microemulsion, and 1.0 to 20.0 wt% of a capsule with respect to a total weight of the cosmetic composition, and a method for producing the same. When the cosmetic composition according to the present invention is applied to skin, a high content of oil in a capsule is slowly emitted, so a skin moisturizing effect is maintained for a long time. Compared to general solubilizing-type low viscosity mist having rare continuous moisturizing maintaining strength, a skin moisturizing effect is remarkably excellent. Furthermore, since a capsule included in a cosmetic composition according to the present invention is large to be visually shown, a discriminated appearance can be exhibited. A formulation is formed in a two-layered structure, so visual interests may be provided to consumers through a way of shaking and mixing components in an upper layer part and a lower layer part.

Description

TECHNICAL FIELD The present invention relates to a two-layered high moisture-curing cosmetic composition containing a capsule and a method for producing the same,

The present invention relates to a two-layered high moisture-curing cosmetic composition comprising an oil-containing capsule and a method of preparing the same, and more particularly to a cosmetic composition comprising a microemulsion, a capsule, a polyol and an thickening agent, It is possible to provide a visual fun to consumers by shaking and mixing components of the upper and lower layers at the time of use, and it is also possible to provide a high-content Oil and microemulsions, and having excellent skin moisturizing effect, and a method for producing the same.

Mist is a kind of moisturizer, and its main ingredient is composed of water, which is sprayed on the face and serves to supply water. Therefore, Mist provides immediate moisture to dry skin, so it keeps the skin fresh and moisturized all day long, and instantly soothes the skin. Therefore, it is known that mist is easy to use and gives immediate moisturizing effect, and it is becoming popular as a moisturizing item that women use most frequently. However, in recent years, there are more and more users who mist dry the skin. The reason for this is that when mist is sprayed on the face from time to time, the alcohol tends to evaporate in a short time as it evaporates, and when it evaporates, it draws moisture inside the skin and evaporates along with it, .

Generally, the low boiling point mist type of the solubilization type is a method of increasing the solubilization formulation by increasing the water phase in the water phase and satisfying the user's taste because there is a limitation in containing the oily ingredient which can be felt in the general emulsion formulations Although there is a shortage and sufficient for short-term moisture absorption, the moisture retention in the skin when sprayed onto the skin is much lower than that of ordinary emulsification formulations. Therefore, although immediate water supply is possible, there is a problem in that the maintenance of moisture retention is inferior. As a solution to this problem, there is an emulsion type in which a microemulsion having a diameter of dispersed particles of about 10 to 200 nm is dispersed as a kind of emulsion in a formulation and a general low viscosity emulsion type. The low viscosity emulsion type has good moisturizing and holding power, but when a high content of water-soluble and oil-soluble active ingredients are blended, it is difficult to stabilize and a large cost is consumed in manufacturing. In addition, the emulsion type in which the microemulsion is dispersed has a lower moisture retention ability than a low viscosity emulsion, but consumes less cost in manufacturing and can effectively stabilize a high content of water-soluble and oil-soluble active ingredients. Therefore, a microemulsion is added to the mist formulation, and an oil-in-water (O / W) type emulsion having fine and uniform emulsion particles can be produced in many products using other emulsions such as pharmaceuticals, It is very important in stability. It is known that the microemulsion (O / W type) is a type of emulsion in which the diameter of dispersed particles is about 10 to 200 nm and the state and physical properties are variously changed according to the production method, the type of emulsifier and the composition of the raw material. Stable emulsions having low viscosity have been developed by the use of active agents, the PIT emulsification method, the D phase emulsification method and the use of emulsifiers for low viscosity (polymeric surfactant and glucoside type).

On the other hand, recently, a cosmetic composition for realizing product differentiation through various concepts such as appearance difference and active ingredient inclusion has been developed. Among them, there is a technique which includes capsules which give a role of sustaining the effect for a long time by gradually releasing the effective ingredient gradually upon application to the skin, thereby making it possible to maximize the efficacy by containing the active ingredient in the capsules. The types of capsules include various kinds of capsules such as natural ingredients, collagen or gelatin, capsules containing acacia gum and cellulose gum and cross-linking agent, vegetable butter, beads containing high alcohol, etc. These capsules are classified into natural oils , And has the advantage of maximizing the moisturizing effect of the moisturizing component shampoo oil formulation. However, when a capsule is applied to a general mist product, there is a problem in the stability of the formulation, such as a sinking of the capsule, and a high cost is incurred when a large amount of the capsule is applied.

Background Art [0002] Prior Art 1 (Korean Patent Registration No. 10-1007185 B1) for providing a cosmetic composition containing a capsule is directed to a cosmetic capsule and a cosmetic composition containing the same, which is easy to handle before being added to a cosmetic, A method of providing a cosmetic capsule and a cosmetic composition containing the cosmetic capsule which can impart a good feeling by giving a feeling of good feeling and stability as well as a stability that the shape is not collapsed or the shape is not changed even by Lt; / RTI > The above-mentioned technique has a stability that the shape of the capsule is not collapsed or the shape is not changed even when the capsule is stirred at the time of manufacturing the cosmetic, but the problem of the capsule sinking when the formulation is applied to the capsule has not been solved.

In addition, various developments have been attempted in order to differentiate the product through various concepts as well as a technique of differentiating the appearance by applying the capsule as described above. Among them, the formulation has a two-layer structure divided into an upper layer and a lower layer Background Art [0002] Prior art 2 (Korean Patent Laid-Open Publication No. 10-2011-0084053 A) is a technique for developing a cosmetic composition of two layers and differentiating appearance, and relates to a two-layer cosmetic composition having a moisturizing effect and a manufacturing method thereof. The above-mentioned technology provides an excellent detergency when applied to the skin, a moisturizing effect added to the skin after the cleansing and moisturizing effect of the skin after the cleansing, and minimizes the skin drying phenomenon which may occur after the use of the cleansing agent, And has a structure in which components of the upper layer and the lower layer are shaken at the time of use to mix with each other to provide visual fun to consumers, and a manufacturing method thereof is disclosed. However, since the above technique requires a large amount of the surfactant, there is a problem that skin side effects and unpleasant feeling can be caused.

(Korean Patent Registration No. 10-1007185 B1) (Korean Patent Laid-Open Publication No. 10-2011-0084053 A)

Accordingly, the present inventors have succeeded in solving the problems of submerging capsules, microemulsions, polyols, and thickeners in a two-layered form, which is divided into an upper layer and a lower layer, by shaking the components of the upper and lower layers during use And to develop a cosmetic composition having a high moisturizing effect by containing a high amount of oil in a capsule. It was found that the content of the thickening agent was very important for adjusting the appearance of the two-layered phase as a result of various inventive efforts and a long time for developing the present invention, and it was found that the microemulsions were suitably applied for fine spraying and moisturizing effect And it was found that it is important to appropriately adjust the content of the polyol in order to have proper moisture holding ability and feeling. As a result, by adjusting the optimum ratio of capsules, microemulsions, polyols, and thickeners, the formulation can be composed of a two-layer structure divided into an upper layer and a lower layer, and at the same time, a formulation having a high moisturizing effect And succeeded to complete the present invention.

Accordingly, it is an object of the present invention to provide a cosmetic composition comprising a cosmetic composition comprising 0.1 to 15.0 wt% of polyol, 0.1 to 0.5 wt% of polyol, 0.1 to 10.0 wt% of microemulsion, and 1.0 to 20.0 wt% And a method for producing the same.

In order to achieve the object of the present invention, the present invention provides a cosmetic composition comprising 0.1 to 15.0 wt% of polyol, 0.1 to 0.5 wt% of polyol, 0.1 to 10.0 wt% of microemulsion, and 1.0 to 20.0 wt% of oil- Wherein the cosmetic composition is a cosmetic composition.

According to another aspect of the present invention, there is provided a method for manufacturing the two-layered high moisture-imparting cosmetic composition.

Hereinafter, the present invention will be described in detail.

The cosmetic composition of the present invention comprises 0.1 to 15.0 wt% of a polyol, 0.1 to 0.5 wt% of a polyol, 0.1 to 10.0 wt% of a microemulsion, and 1.0 to 20.0 wt% of an oil-containing capsule, based on the total weight of the cosmetic composition.

The composition ratio of the main components constituting the cosmetic composition of the present invention is characterized by having a high moisturizing function and having a two-layered formulation. As a result of testing after preparing various kinds of components of the above components, it was found that the capsules were uniformly distributed at the time of spraying and that the properties of the two-layered form were maintained even at 50 캜, which is a high temperature, in Examples 1 to 4 Experimental Example 1). Therefore, in order to confirm the degree of the moisturizing ability of Examples 1 to 4, changes in moisture content and moisture content of the products sold on the market were compared for two weeks. The moisture content of commercial products increased by 31.5% and the moisture evaporation decreased by 15.8%. The moisture retention of Examples 1-4 of the present invention increased by an average of 60% and the moisture evaporation decreased by an average of 23%. In Examples 1 to 4 of the present invention, the moisture holding capacity is increased by about two times and the moisture evaporation amount is reduced by 1.5 times, which is higher than that of a commercial product.

The capsule is an oil-containing capsule having an oil content of 50 to 90% by weight in order to maximize the moisturizing effect. The capsule is 0.5 to 1 cm in diameter and has a size enough to be visually perceived, (See FIG. 1).

The oil component contained in the capsule is not particularly limited, and any oil that can be used in cosmetics can be used. For example, vegetable oil, animal oil, mineral oil and synthetic oil can all be used, and it is also possible to use a mixture of these oils. Specific examples thereof include oils selected from the group consisting of olive oil, castor oil, palm oil, avocado oil, almond oil, ragweed oil, apricot oil, rose oil, macadamia nut oil, mink oil, liquid paraffin, petroleum jelly, isopropyl myristate, , Green tea oil, sunflower oil, grape seed oil, argan oil, hydrogenated polydecene, etc., but the present invention is not limited thereto. Preferably, it may be argan oil or hydrogenated polyphenylene, and more preferably may be a mixture of the two oils.

The oil capsules may contain at least one or more crosslinking agents selected from the group consisting of collagen, gelatin, agar, acacia gum, and cellulose gum.

The capsule may contain 1.0 to 20.0% by weight based on the total weight of the cosmetic composition. When the capsule is less than 1.0% by weight based on the total weight of the cosmetic composition, the effect of the active ingredients contained in the capsule is insignificant, and since the content of the capsule is small, the capsule is not visible, If the content exceeds 20.0% by weight, the feeling of use may be deteriorated due to excessive capsules at the time of injection.

The polyol may be at least one of glycerin, butyleneglycol, propylene glycol, dipropylene glycol, diglycerin, pentylene glycol, isoprene glycol, erythritol and panthenol, which is used for moisturizing the skin and preventing freezing in winter, Use one or more of them. The polyol may comprise 0.1 to 15.0% by weight, more preferably 0.1 to 10% by weight, based on the total weight of the cosmetic composition. When the polyol is less than 0.1% by weight based on the total weight of the cosmetic composition, the ability to retain moisture is weak and the feeling of moisturizing is poor. When the polyol is more than 15.0% by weight,

The thickeners include, but are not limited to, at least one selected from the group consisting of carbomer, guar gum, xanthan gum, carboxymethyl cellulose, hydroxyethyl cellulose, sodium polyacrylate, and hydroxypropyl cellulose. It can be a combination of two or more. The thickening agent may include 0.1 to 0.5% by weight based on the total weight of the cosmetic composition. The gradual increase in the composition ratio of the cosmetic composition can maintain the two-layer formulation. When the amount is less than 0.1% by weight based on the total weight of the cosmetic composition, the viscosity of the formulation is low, so that when the components of the upper layer and the lower layer are shaken before use, the capsule is dispersed in the formulation for a short time, If the amount is more than 0.5% by weight, the viscosity of the formulation is so high that the mist can not easily be discharged, and the capsules do not separate in the formulations, and the properties of the two layers can not be exhibited.

The microemulsion has a diameter of 70 to 100 nm and is characterized in that it contains at least one or more of a surfactant PEG emulsifier, a glucoside emulsifier, a polyglyceryl emulsifier, a glyceryl emulsifier and lecithin.

The 'microemulsion' is a kind of emulsion, and the diameter of the dispersed particles is about 10 to 200 nm, preferably 70 to 100 nm. Transparent or semitransparent (scattering of white light) liquid, and means a thermodynamically stable system.

The microemulsion may be prepared by a single emulsification method selected from the PIT Emulsification Method and the D-phase Emulsification Method, though it is not limited thereto.

The PIT Emulsification Method is an emulsification method using an HLB value of a nonionic surfactant. As the temperature of a composition comprising a three-component system of water, oil and a nonionic surfactant increases, the hydrophilic ethylene oxide This is an emulsification method that utilizes the principle of a surfactant that reduces the hydrogen bonding with water to reduce the hydrophilic property. At this time, the composition composed of the three-component system forms an O / W (oil in water) type emulsion at a certain temperature or lower and a W / O (water in oil) type emulsion at a certain temperature or higher. This temperature is called "Phase Inversion Temperature (PIT) ". That is, the phase temperature may be referred to as the temperature at which the hydrophilic-lipophilic property of the emulsion system is in equilibrium. Since the interfacial tension between oil-surfactant and water is extremely low at this temperature, oil and water can easily be mixed even if only a small amount of force is applied, and separation due to specific gravity difference can easily occur. In addition, O / W type conversion from W / O type to O / W type showed that the O / W ratio was changed by catastrophic inversion and affinity change of surfactant to oil and water. W emulsion can be made.

The D-phase emulsification method is a method in which D phase is formed by nonionic surfactant / polyhydric alcohol / water by emulsification using a surfactant phase (D phase) using HLB value, Emulsified in a transparent gel phase, and then diluted with water to prepare an O / W type emulsion.

According to a preferred embodiment of the present invention, the microemulsion may contain 0.1 to 10.0% by weight based on the total weight of the cosmetic composition. When the amount of the microemulsion is less than 0.1 wt% based on the total weight of the cosmetic composition, fine spraying is difficult and the formulation gradually becomes transparent at high temperatures, resulting in poor stability of the composition. When the microemulsion is more than 10.0 wt% .

The cosmetic composition of the present invention may further include additives commonly used in the art in addition to the above-mentioned effective ingredients. For example, conventional additives commonly used in the cosmetics field may be further included. When formulating into cosmetics, reference can be made to the contents disclosed in 'Ternational cosmetic ingredient dictionary, 6th ed., The cosmetic, Toiletry and Fragrance Association, Inc., Washington, 1995'. Which are incorporated herein by reference.

Preferably, the composition further comprises one or more of a surfactant, an emulsifier, a soap acid, a solvent, a binder, a diluent, a lubricant, a stabilizer, an antioxidant, water, a lower alcohol, a chelating agent, a colorant, a preservative, Antimicrobial agents, antifungal agents, enzymes, plant or mineral oils, fats, fluorescent substances, fungicides, excipients, humectants, fragrances, fragrance carriers, preservatives, proteins, silicones, solubilizers, sugar derivatives, sunscreens, vitamins, plants And one or more pharmacologically acceptable excipients selected from the group consisting of extracts and waxes.

In addition, the cosmetic composition of the present invention may be applied to cosmetics such as lotion, spray type lotion, facial lotion, body lotion, etc. such as soft lotion or nutrition lotion, cream, essence such as nutrition cream, Such as foundation, foundation, powder, cleansing lotion, make-up remover such as cleansing oil, cleansing foam, soap, body wash and the like, such as makeup ointment, spray, gel, pack, sunscreen, makeup base, liquid type or spray type Lt; / RTI > Most preferably a spray type lotion.

The method for producing a two-layered high moisture-moisturizing cosmetic composition according to the present invention comprises the steps of: (1) preparing an aqueous phase by mixing a polyol and a thickening agent, warming, dissolving and homogenizing the aqueous phase; (2) a solubilization part homogenizing step of mixing the ethanol and the solubilizing agent to prepare a solubilized part and then dissolving and homogenizing the solubilized part; (3) a step of homogenizing the aqueous phase / solubilized phase by adding the solubilizing agent and the neutralizing agent to the water, and then stirring the same in a vacuum emulsification tank to homogenize; And (4) mixing and homogenizing the microemulsion and the capsules in the aqueous solution / solubilization unit, and then mixing the preservative and cooling to 30 to 40 ° C.

More specifically, the process for preparing a two-layered high moisture-moisturizing cosmetic composition according to the present invention comprises: (1) mixing 0.1 to 15.0% by weight of polyol and 0.1 to 0.5% by weight of polyol, based on the total weight of cosmetic composition, Lt; RTI ID = 0.0 > 78 C < / RTI > to dissolve and homogenize; (2) a solubilization part homogenizing step of mixing 2.0 to 15.0% by weight of ethanol and 0.1 to 1.0% by weight of a solubilizing agent in the solubilized part, and dissolving and homogenizing the solubilized part at 1 to 35 ° C; (3) adding the solubilizing agent and the neutralizing agent to the water and stirring the solution with HOMO at a rotation speed of 2,500 to 3,500 rpm in a vacuum emulsification tank to homogenize the aqueous phase / solubilized product; And (4) mixing and homogenizing 0.1 to 10.0% by weight of the microemulsion and 1.0 to 20.0% by weight of the capsule in the water-soluble / solubilized portion, and then mixing the preservative and cooling to 30 to 40 ° C.

In the step (1) of the above-described production method, the water-receiving part may include at least one or more than one of raffinose, betaine and glycine as moisturizing agents to impart a moisturizing effect.

In the step (2) of the above production method, any of those known in the art may be used as the solubilizing agent contained in the solubilizing part. For example, in the present invention, anionic surfactant, cationic surfactant, amphoteric surfactant and nonionic surfactant can be used as the surfactant, more preferably anionic surfactant and nonionic surfactant can be used . Specific examples of the anionic surfactant include alkyl acyl glutamates, alkyl phosphates, alkyl lactylates, dialkyl phosphates and trialkyl phosphates. Specific examples of the nonionic surfactant include polysorbate, phage-40 hydrogenase, phage-60 hydrogenase, alkylpolyglycoside, polyglycerylester, sucroester, Corses-7 / 1-phage-9-lauryl glycol ether / pyridine-40hydrogenate castor oil, and mixtures thereof.

When the cosmetic composition of the present invention is applied to the skin, a high content of oil is gradually released in the capsule to thereby maintain the skin moisturizing effect for a long time, and the skin moisturizing effect is lower than that of the general solubilization type low viscosity mist, Remarkably superior. In addition, since the capsules contained in the cosmetic composition of the present invention are large enough to be visually visible, they can show differentiated appearance and formulate the two-layered form by controlling the proper proportions of the components, thereby shaking the components of the upper and lower layers It has the effect of giving consumers visual fun.

Fig. 1 shows an appearance of a cosmetic composition prepared from Example 1, wherein the formulation is composed of a two-layer structure divided into an upper layer portion and a lower layer portion, and the colored portion of the upper layer is a capsule.

Experimental Example  1: Properties and physical properties

From the results of Examples 1 to 12, it was found that the two-layered high moisture-curing cosmetic composition containing the capsules had the mixing ratios determined in Examples 1 to 4, And spraying was smoothly carried out. Also, it was confirmed that the active substances were stable and stable for a long period of time even under severe conditions such as 50 ° C.

However, in Example 5, the content of glycerin as a polyol with respect to the total weight of the cosmetic composition was less than 0.1% by weight, and the water holding ability was weaker than that in Examples 1 to 4, When the content of glycerin was more than 15.0 wt%, the stability of the formulation was excellent at all temperatures, but it was thick and frustrating.

In Example 7, since the content of carbomer, which is an increasing agent relative to the total weight of the cosmetic composition, is less than 0.1% by weight, the viscosity of the formulation is low, so that when the capsule is shaken before use, It was not easy to uniformly discharge the capsules. In Example 8, the content of carbomer, which is an increasing agent relative to the total weight of the cosmetic composition, exceeded 0.5% by weight and the viscosity of the formulation was so high that mist discharging was not easy, And it was not possible to show the two-layered structure.

In Example 9, the content of collagen oil capsules was less than 1.0% by weight based on the total weight of cosmetic composition, and the content of capsules was so low that no layer was formed, In Example 10, the content of the collagen oil capsules was more than 20.0% by weight based on the total weight of the cosmetic composition, thereby causing the user to feel an unpleasant taste and difficulty in commercializing the cosmetic composition due to the increase in the unit price.

In Example 11, the content of the microemulsion was less than 0.1% by weight based on the total weight of the cosmetic composition, and the feeling of use was lighter and faster in absorption than in Example 1, while fine injection was difficult. In Example 12, The prepared micro-emulsion had a microemulsion content exceeding 10.0% by weight, but it was densely applied, but it was slow in absorption and felt a lot of oil, and it was difficult to commercialize it due to an increase in unit price. In Example 11, the formulation gradually became transparent at high temperature, and the stability of the property was not good. In Example 12, the formulation stability was excellent at all temperatures.

Experimental Example  2: Skin moisturizing effect

In order to confirm the skin moisturizing effect when the cosmetic composition obtained from Examples 1 and 4, which were excellent in the physical properties and properties of Examples 1 to 12, was applied to the skin, the subjects (5 women, mean age 34.8 years ) Were conducted. As a positive control, a solubilization type general liquid composition for moisturizing, which is on the market, was set up and skin moisture content and moisture evaporation amount were measured for 2 weeks using a corneometer (CK electronics, Germany) and a Tewameter (CK electronics, Germany) Respectively. Table 3 shows the moisture content, and Table 4 shows the moisture evaporation.

As a result, as shown in Table 3 and Table 4, the moisture content of the stratum corneum was increased by 31.5% and the moisture evaporation was decreased by 15.8% after 2 weeks from the application of the general liquid sample . However, in the case of Examples 1 to 4, moisture retention increased by 64.2%, 58.6%, 57.0% and 60.0%, respectively, after two weeks of application to the skin, and the water evaporation amount decreased by 23.5%, 25.3%, 24.4% and 19.7% , It was found that the water content of the stratum corneum of the skin applied with the samples of Examples 1 to 4 was higher than that of the general liquid sample. Therefore, it was confirmed that the skin moisturizing effect of the two-layer high moisture-controlling cosmetic composition containing the capsule of the present invention is excellent.
