Description

A cosmetic composition containing a capsule having a base makeup function and a manufacturing method thereof {Cosmetic composition including capsules for base makeup and preparing method thereof}

The present invention relates to a cosmetic composition containing a capsule having a base makeup function and a manufacturing method thereof, and more particularly, a pigment component for creating smooth and bright skin is contained in a fine capsule and stably dispersed in the aqueous component, thereby providing a feeling of moisture. It relates to a base makeup cosmetic composition that is excellent and can be applied uniformly and smoothly without applying a large force, and a method for preparing the same.

As the largest organ of the human body, the skin is an important organ that plays various roles such as protective function, barrier function, temperature control function, excretory function, and respiratory function. However, due to various external environmental factors such as strong ultraviolet rays, fine dust, excessive use of air conditioners/heaters, and internal factors such as aging, stress, and nutritional deficiencies, skin cells are damaged and cell proliferation is not performed properly. Not only the function is not effectively performed, but also cosmetic problems such as wrinkles, loss of elasticity, and keratinization occur.

The skin located at the outermost part of the human body is considered to be more beautiful and attractive as it becomes brighter and smoother, and various efforts are being made to maintain such beautiful skin. In the past, skin care and decoration were considered exclusively for women, but in recent years, due to the development of media and increased interest in appearance, efforts to maintain beautiful skin regardless of gender and age, and to use makeup cosmetics to decorate it to look more beautiful This is done in various ways.

Make-up cosmetics contain pigment components, and have a function of changing skin color or correcting to have a certain skin tone, and may be separately applied to various parts of the skin, eyes, lips, etc. depending on the formulation.

In particular, various base makeup cosmetics such as primer, tone-up cream, BB cream, makeup base, and foundation are essentially used in the first stage of makeup to uniformly correct the skin tone and make it brighter or darker. These base makeup cosmetics are manufactured to enable the expression of healthy-looking skin while being uniformly adhered to the skin, and to have a soft finish.

Among the base makeup cosmetics, oil-in-water cosmetics have excellent moisture and have a refreshing feeling.

These oil-in-water cosmetics can be prepared by various methods, and when formed into an emulsion composition of a single formulation using a surfactant, which is an emulsifier, skin irritation may be caused by the emulsifier, and when the amount of the emulsifier is insufficient, the phases are separated. Problems may arise.

As another method, there is a method of preparing an oily component in the form of a fine capsule in advance using starch or cellulose, and dispersing it in the aqueous component. There is discomfort, and a foreign body feeling due to the capsule residue may be felt, which may cause discomfort during use.

Therefore, it is necessary to develop a new formulation of oil-in-water cosmetics that is easy to use and does not use an emulsifier to minimize skin irritation.

Hereinafter, prior to being described in detail through preferred embodiments of the present invention, terms or words used in the present specification and claims should not be construed as being limited to conventional or dictionary meanings, and meanings consistent with the technical spirit of the present invention. and should be interpreted as a concept.

Throughout this specification, when a part "includes" a component, it means that other components may be further included, rather than excluding other components, unless otherwise stated.

Throughout this specification, "%" used to indicate the concentration of a specific substance is (weight/weight)%, solid/liquid (weight/volume)%, and liquid, unless otherwise specified. /liquid means (volume/volume)%.

In each step, the identification code is used for convenience of description, and the identification code does not describe the order of each step, and each step may be performed differently from the specified order unless the specific order is clearly stated in the context. have. That is, each step may be performed in the same order as specified, may be performed substantially simultaneously, or may be performed in the reverse order.

The term "capsule" used in the present invention refers to not only capsules in the conventional sense in which the contents exist inside the shell, but also particles in which the contents themselves exist in the form of drops or drops without a material that functions as a separate shell. It can also contain meaning.

Hereinafter, an embodiment of the present invention will be described. However, the scope of the present invention is not limited to the following preferred embodiments, and those skilled in the art can implement various modified forms of the contents described herein within the scope of the present invention.

The present invention relates to a cosmetic composition containing a capsule having a base makeup function and a manufacturing method thereof.

Specifically, a cosmetic composition containing a capsule having a base makeup function that can provide a high moisture feeling and can be applied uniformly and smoothly without applying a large force by uniformly dispersing the oil phase containing the pigment component in the aqueous phase in the form of a fine capsule. and to a method for manufacturing the same.

One embodiment of the present invention relates to a cosmetic composition containing the capsule having the base makeup function, wherein the cosmetic composition includes an aqueous phase and an oil phase uniformly dispersed in the form of a capsule in the aqueous phase.

The aqueous phase includes purified water, an aqueous moisturizer, an additive and an aqueous thickener, and the oil phase includes a moisturizing oil, a pigment and a capsule former.

At this time, the water phase and the oil phase do not contain a separate emulsifier, so the oil phase and the water phase are not formed into an emulsified emulsified composition. It has a well-dispersed formulation. In particular, the oil phase does not include a separate shell, and the contents themselves are formed in the form of capsules that exist in the form of particles and can be uniformly dispersed in the aqueous phase.

As such, since a separate emulsifier is not included, skin irritation caused by the use of cosmetics can be prevented.

In addition, since the fine capsules have a uniformly dispersed formulation in the aqueous phase as described above, when applied to the skin, the moisture is primarily supplied to the skin by the aqueous phase, and the shape of the capsule having a makeup function is destroyed and applied. Because makeup is made, it can provide a soft feeling of use without being stiff unlike general makeup cosmetics, it can prevent dry feeling due to the use of cosmetics, and it is finished with a fresh feeling after application, so it has excellent spreadability and application feeling. .

In the present invention, a capsule former is used to form such a capsule. In particular, since a gelling agent such as cellulose or starch is not used for forming the shell of the capsule, there is no foreign body feeling due to the use of these gelling agents, and there is an advantage that excessive force is not required to break the gel capsule during application.

The diameter of the capsule may be in the range of 0.1 ~ 2.0mm. Here, the diameter means the longest among the lengths from one end to the other end of the capsule.

In particular, when the diameter of the capsule exceeds 0.1mm, the capsule is not applied in a uniform amount on the entire surface of the skin when the cosmetic composition is used, and the function of hiding, changing and supplementing the skin color is unevenly expressed. Since it is difficult to implement, the maximum diameter is preferably formed to be less than 0.1 mm.

The oil phase may be included in an amount of 3 to 45 parts by weight based on 100 parts by weight of the aqueous phase, and in particular, when the content of the oil phase exceeds 45 parts by weight, formulation stability is deteriorated.

The water phase includes purified water, an aqueous moisturizer, an additive, and an aqueous thickener. Specifically, it may include 8 to 20% by weight of an aqueous moisturizer, 1 to 5% by weight of an additive, 0.5 to 6 parts by weight of an aqueous thickener, and the remaining amount of purified water.

The viscosity of the aqueous phase may be in the range of 8,000 to 18,000 cP, and the aqueous phase alone has flow properties similar to skin, toner, essence, serum, and lotion.

When the viscosity of the aqueous phase is formed in this way, fine capsules may be formed in the process of mixing the aqueous phase and the oil phase during the manufacturing process, and the size of individual capsule particles is formed uniformly with the aqueous phase in the cosmetic composition discharged from the container. Since the weight ratio of the oil phase is constant, it is possible to secure the makeup quality. In addition, since the capsule is uniformly dispersed in the entire water phase and left to stand for a long time, the capsule does not settle, so it can be used conveniently without a separate operation of shaking the container.

The aqueous moisturizer is a component added for primary skin moisturizing when using the cosmetic composition, and is added in an amount of 8 to 20% by weight in the aqueous phase. If the content of the water-based moisturizer is less than 8% by weight, the moisturizing effect by the water-based moisturizer is insignificant, and if it exceeds 20% by weight, the formulation stability is poor and may cause a foreign body feeling, stickiness, or irritation during use. It is preferable to be

As such an aqueous moisturizer, various known substances exhibiting a moisturizing effect may be used. For example, a general humectant such as glycerin, propanediol, dipropylene glycol, polyol or polyglycerin-3 may be used. Alternatively, functional humectants such as trehalose, betaine, adenosine, niacinamide, panthenol, allantoin, hyaluronic acid, squalene or ceramide NP may be used together with these general moisturizers. , soothing, conditioning, skin regeneration, and additional functions such as exfoliation can be given.

The additive is a component added to give an additional function to the cosmetic composition, and may be included in an amount of 1 to 5% by weight in the aqueous phase. If the content of the additive is less than 1% by weight, the effect of improving the function by the additive is insignificant, and if it exceeds 5% by weight, skin irritation may be induced due to the excessive additive content, and the formulation stability of the composition may be reduced or make-up or It is preferable to add within the above-mentioned weight range because problems such as deterioration of the original function such as moisturizing occur.

At least any one or more of a sequestering agent, a preservative, a pH adjusting agent, and a pigment may be added as such an additive, and a sequestering agent, a preservative and a pH adjusting agent may be preferably used.

The sequestering agent is added to improve the stability and feeling of use of the aqueous phase by blocking the metal ions contained in the aqueous phase. Such a sequestering agent, for example, at least any one or more of anhydrous citric acid, anhydrous tetrasodium pyrophosphate, anhydrous trisodium phosphate, sodium metaphosphate, sodium citrate, sodium polyphosphate, EDTA-4Na and EDTA-2Na may be used, but is not limited thereto.

The preservative is a component added to inhibit or prevent the growth of microorganisms in the cosmetic composition, and various known preservatives may be used. In this case, it is preferable not to use parabens or phenoxyethanol, which can cause allergic skin reactions as preservatives, and 1,2-hexanediol, 1,3-butylene glycol, which has high skin safety and is eco-friendly. Col (1,3-Butylene glycol), Caprylyl Glycol, Glyceryl Caprylate, p-Anisic Acid, Pentylene Glycol and Ethyl At least one selected from the group consisting of hexylglycerin (Ethylhexylglycerin) may be used, but is not limited thereto.

The pH adjusting agent is added to adjust the pH of the aqueous phase to stabilize the properties of the aqueous phase, and thus the formulation in which the capsule of a fine size is dispersed in the aqueous phase can be stably maintained. As such a pH adjusting agent, for example, at least one selected from the group consisting of tromethamine, arginine, potassium hydroxide and sodium hydroxide may be used, but is not limited thereto.

The aqueous thickener is added to control the viscosity of the aqueous phase to provide smooth application, to increase the skin absorption of the aqueous phase to improve the moisturizing effect, and to stably maintain the dispersed state of the capsule.

Such an aqueous thickener, for example, is at least one selected from the group consisting of agar, ammonium acryloyl dimethyl taurate / VP (vinyl pyrrolidone) copolymer and hydroxyethyl acrylate / sodium acryloyl dimethyl taurate copolymer More than one can be used.

The aqueous thickener may be included in an amount of 0.5 to 6% by weight in the aqueous phase part, and when the content of the aqueous thickener is less than 0.5% by weight, the viscosity of the aqueous phase part is excessively low, so that the capsule is not uniformly dispersed as a whole and settles. . On the other hand, when the content of the aqueous thickener exceeds 6% by weight, the viscosity of the aqueous phase is excessively high, which causes a problem that the size of the microcapsule is not uniformly formed. Since there is a problem in that makeup performance is not constant, it is preferable that the aqueous thickener be included in the above-mentioned weight range in order to secure makeup quality during use.

When the aqueous thickener is included in the above-mentioned weight range, since the viscosity of the aqueous phase is formed in the range of 8,000 to 18,000 cP, the above-described problem can be prevented.

The oil phase includes moisturizing oil, pigment and capsule former. The oil phase is uniformly dispersed in the form of a capsule having a diameter in the range of 0.1 to 2.0 mm in the water phase.

The oil phase includes 10 to 500 parts by weight of a pigment and 10 to 500 parts by weight of a capsule former based on 100 parts by weight of the moisturizing oil.

The viscosity of the oil phase may be 30,000 cP or more. As such, as the high viscosity is formed, the aqueous phase and the oil phase are more difficult to mix with each other due to the polarity difference as well as the viscosity difference, so that the capsule formed of the oil phase is not mixed with the aqueous phase. It may exist in a dispersed state in the water phase.

In addition, as it has a high viscosity as described above, the self-cohesive force of individual capsules is strengthened, so that individual particle phases can be stably maintained without being easily combined or aggregated with neighboring capsules.

While further enhancing this effect, the viscosity of the oil phase may be 30,000 to 40,000 cP in order to provide an effect of preventing stickiness or a feeling of foreign body caused by the oil phase.

The moisturizing oil imparts a polarity different from that of the water phase to the oil phase, so that the capsule formed of the oil phase is not mixed or emulsified with the aqueous phase, and the capsules are present in the aqueous phase in the form of individual particles. In addition, the moisturizing oil gives a moisturizing feeling when the cosmetic composition is applied to the skin, and can be applied gently.

As a moisturizing oil, various known oils capable of imparting moisture to the skin may be used, and as mentioned above, a non-polar oil may be used to separate it from the aqueous phase. Preferably, a non-polar moisturizing oil for imparting a silky and dry finish without being sticky may be used.

For example, at least one of natural oil, ester-based oil, hydrocarbon-based oil, and silicone oil may be used as the moisturizing oil.

The natural oil may be an oil obtained from a plant existing in nature. Such natural oils include, for example, olive oil, coconut oil, sunflower seed oil, avocado oil, orange oil, macadamia seed oil, lemon oil, pine nut oil, jojoba seed oil, green tea seed oil, rosehip oil, damask rose oil. Oil, Brazil nut seed oil, drumstick seed oil, grapefruit seed oil, soybean oil, vanilla fruit oil, etc. may be used, but are not limited thereto.

Ester-based oils are ester compounds of fatty acids and fatty alcohols. Examples of ester-based oils include dipentaerythrityl hexa C5-9 acid esters, C12-15 alkyl octanoates (C12-15 alkyl octanoate), myristyl lactate, cetyl ethylhexanoate, cetyl octanoate, isopropyl myristate, octyldodecyl myristate, hexyl laurate, di (C12-13) alkyl malate, myristyl lactate, octyldodecyl stearoylstearate, At least one selected from the group consisting of diisostearyl malate, pentaerythrityl tetraethylhexanoate and diglyceryl triisostearate may be used, However, the present invention is not limited thereto.

Petroleum-based oils such as liquid paraffin, vaseline, and isoparaffins as hydrocarbon-based oils; synthetic oils such as hydrogenated polydecene, synthetic squalane, and polybutene; Plant-based oils such as vegetable squalane and hydrogenated squalane may be used, but the present invention is not limited thereto.

Silicone oils such as cyclopentasiloxane, cyclohexasiloxane, dimethicone, methyltrimethicone, amodimethicone, phenyltrimethicone, dimethicone/trimethyl siloxy silicate, diphenyldimethicone, triphenylmethicone , at least one of a homogeneous dispersion of dimethicone and dimethiconol, and a copolymer of cyclopentasiloxane and dimethicone/vinyldimethicone, but is not limited thereto.

The pigment is a component added to impart skin hiding power and color to the cosmetic composition, and as the pigment is added, effects such as directing a different skin color or changing the original skin tone when the cosmetic composition is applied to the skin can be obtained. have.

As such, the pigment is added, and the cosmetic composition of the present invention can function as a base cosmetic such as a primer, a tone-up cream, a BB cream, a makeup base, and a foundation.

The pigment may be included in an amount of 10 to 500 parts by weight based on 100 parts by weight of the moisturizing oil, and the skin hiding power may be changed according to the content of the pigment. However, if the content of the pigment is less than 10 parts by weight, it is difficult to use it as a base cosmetic because the skin hiding power is insignificant. It is preferably included within one weight range.

As the pigment, at least one base pigment selected from the group consisting of titanium dioxide, aluminum oxide, zinc oxide, talc, kaolin, mica, silica, barium sulfate, boron nitride, calcium carbonate and hydroxyapatite, zirconium oxide, cerium oxide , zinc oxide, iron oxide (black, yellow or red), chromium oxide, manganese violet, ultramarine blue, chromium hydrate, chromium oxide green, ferric blue, and at least one colored pigment selected from the group consisting of metal powder, etc. However, the present invention is not limited thereto.

The capsule former is a component that is added to form microcapsules in the range of 0.1 to 2.0 mm in diameter in the water phase in the oil phase part, and as the capsule former is added, the cohesive force of the capsule is improved, so that the capsule can be formed without using a separate encapsulant. It can be formed in the form of microparticles or microcapsules by itself, and such a formulation can be stably maintained for a long time.

The capsule former may be included in an amount of 10 to 500 parts by weight based on 100 parts by weight of the moisturizing oil. When included in an amount of less than 10 parts by weight, the cohesive strength improvement effect is insignificant, so that microcapsules are not formed, and even when microcapsules are formed, shaking the product When an external force that provides a stirring force acts, or, conversely, when left alone for a long period of time, individual capsules agglomerate and agglomerate to form large particles rather than fine particles.

On the other hand, when the capsule former is included in excess of 500 parts by weight, it is difficult to form microcapsules of a certain size, and there is a problem in that an unpleasant finishing feeling such as a foreign body feeling or stickiness is formed when using the cosmetic composition, so it is preferable to be included within the above weight range. do.

Hydrogenated vegetable oil as such a capsule former; behenyl alcohol; fatty acids having 16 to 19 carbon atoms; and mixtures of fatty alcohols.

The fatty acid having 16 to 19 carbon atoms may include at least one selected from the group consisting of stearic acid, isostearic acid, palmitic acid and oleic acid, and the fatty alcohol includes cetyl alcohol, stearyl alcohol and cetearyl. At least one or more of alcohol may be included.

When a capsule former containing all four types of ingredients is used, a capsule having a fine size as described above can be formed, and a formulation whose shape is stably maintained in the aqueous phase can be formed, so the above-described It is preferable that all four types of components are included, and when at least one or more of these components are excluded, it is difficult to form a formulation in which the fine capsules are uniformly dispersed in the aqueous phase, so it is preferable to include all four types of components. do.

Preferably, as the capsule former, 80 to 130 parts by weight of behenyl alcohol, 18 to 30 parts by weight of a fatty acid having 16 to 19 carbon atoms, and 20 to 35 parts by weight of a fatty alcohol based on 100 parts by weight of the hydrogenated vegetable oil are mixed. Mixtures may be used.

The oily phase may further contain an oily thickener for adjusting the viscosity of the oily phase if necessary. The content of the oil-based thickener may be 10 to 55 parts by weight based on 100 parts by weight of the moisturizing oil. It is preferable to be included within the above-described weight range, because the viscosity of the product is excessively high, which causes stickiness or foreign body feeling during use.

Such oily thickeners include, for example, dextrin myristate, dextrin palmitate, dextrin stearate, stearalkonium hectorite, disteardimonium hectorite), and at least one selected from the group consisting of quaternium-18 hectorite may be used.

Another embodiment of the present invention relates to a method of manufacturing a cosmetic composition containing a capsule having a base makeup function, and the cosmetic composition containing a capsule having a base makeup function is a base makeup function according to an embodiment of the present invention described above. Since it is the same as the cosmetic composition containing the capsule having the overlapping description will be omitted.

The oil phase preparation step is a step of preparing an oil phase composition by mixing a moisturizing oil, a pigment and a capsule former and stirring at a rotation speed of 200 to 2,000 rpm.

At this time, the stirring temperature is not particularly limited, and when the stirring speed is out of the above range, sufficient stirring is difficult or there is a problem in that excessive bubbles are generated. Therefore, stirring is preferably made to satisfy the above stirring conditions.

In this step, more preferably, at least a portion of the moisturizing oil and the pigment are first mixed to form a uniformly dispersed pigment composition, and then this pigment composition, the remaining moisturizing oil and the capsule former may be mixed secondarily. In this case, the pigment particles can be more uniformly dispersed in the oil phase.

At this stage, an oil-based thickener may be mixed together to adjust the viscosity of the oil phase.

In the step of preparing the water phase, purified water, an aqueous moisturizer, an additive and an aqueous thickener are mixed and stirred at a rotation speed of 200 to 1,500 rpm to prepare a composition for the aqueous phase.

In this step, the stirring temperature is not particularly limited, and if the speed is out of the above range, sufficient stirring is difficult or there is a problem in that excessive bubbles are generated. Therefore, stirring is preferably made to satisfy the stirring conditions described above.

Either one of the oil phase manufacturing step and the aqueous phase manufacturing step may be performed first, or both steps may be performed at the same time, respectively.

In the dispersing step, the aqueous phase composition and the oil phase composition are mixed and stirred at a rotational speed of 1,000 to 9,000 rpm, and the oil phase composition is formed in a capsule form having a diameter of 0.1 to 2.0 mm in the aqueous phase composition and uniformly dispersed. to be.

At this time, if the stirring speed is less than 1,000 rpm, the stirring force is insufficient and the oil phase part is not formed in the form of fine oil particles. It is desirable to do

The cosmetic composition prepared in this way may be prepared as a product by being placed in a container as it is, or may be prepared as a product by being placed in a container after going through a vacuum degassing process if necessary.

Hereinafter, specific actions and effects of the present invention will be described through an embodiment of the present invention. However, this is presented as a preferred example of the present invention, and the scope of the present invention is not limited according to the embodiments.

In addition, as a result of sensory evaluation, all of the moisturizing power, coating power, application uniformity, and finish were evaluated to be excellent. On the other hand, in the case of Sample 1, microcapsules were not formed well during manufacture, only some microcapsules were formed, and the water phase part and oil phase part were layered. Separate results were obtained. Accordingly, it was found that the holding power of the formulation in which the microcapsules were dispersed in the aqueous phase at room temperature and high temperature was also poor.

In addition, when the sample was used, the oil phase and the water phase were not uniformly mixed, so that the coating power and uniformity of coating were somewhat lowered during use.

In the case of Sample 7, the capsule was formed well, but a large capsule having a diameter of up to 5 mm was also formed, indicating that the uniformity of the diameter of the capsule was somewhat deteriorated. In addition, the formulation holding power at room temperature was also good, but the formulation holding power at high temperature was found to be somewhat poor.

As described above, since the capsule diameter deviation is large, the soft and stiff texture appears repeatedly during use, and the coating power is evaluated as somewhat poor, and for the same reason, the coating uniformity is evaluated to be poor. In addition, the moisturizing power and finish were evaluated to be somewhat lower than other samples.

Referring to the experimental results, it was found that the content of the capsule forming agent determines whether or not microcapsules are formed and the dosage form retention power, and the moisturizing power, the application power, the coating uniformity and the finishing feeling are changed.

In particular, it was confirmed that the capsule former is preferably included in an amount of 10 to 500 parts by weight based on 100 parts by weight of the moisturizing oil in the oil phase in order to prepare a cosmetic composition having excellent formulation forming power, holding power, and feeling of use, and more preferably 15.2 to 486.2 It was confirmed that it is preferably included in parts by weight.

[ Experimental example 2]

A cosmetic composition was prepared using the same method as in Preparation Example, but samples having different viscosities of the aqueous phase were prepared by changing the content of the aqueous thickener during the preparation of the aqueous phase. At this time, the content ratio of the aqueous moisturizer and the additive in the aqueous phase was kept constant by changing the content of purified water according to the addition or subtraction of the aqueous thickener.

Thereafter, the formulations of each sample were visually observed in the same manner as in Experimental Example 1, and the results are shown in Table 4.

Looking at the results of Table 4, as in Sample 8, when the viscosity of the aqueous phase is less than 8,000 cP, microcapsules are formed, but it can be confirmed that the formulation retention is poor. In particular, the dispersed state of the microcapsules could not be maintained, and the microcapsules were settling to make the formulation unstable, and at high temperatures, the settled microcapsules agglomerated with each other to form large capsules. This appears to be a result of the fact that the aqueous phase did not form sufficient viscosity to keep the microcapsules in a dispersed state. In the case of Samples 9 to 11, the microcapsules were well formed and the dispersed state in the aqueous phase was at room temperature. However, it was found that both were stable at high temperatures.

In the case of sample 12, it was found that the formation of microcapsules was poor. In particular, there was a problem in that the capsules were not formed into fine particles of a certain size but were formed in a non-uniform size with a maximum diameter of 4.5 mm. In addition, although this formulation was stably maintained at room temperature, layer separation occurred due to poor formulation stability at high temperature.

Therefore, from the results of this experiment, it could be confirmed that the viscosity of the aqueous phase was preferably 8,000 to 18,000 cP, more preferably 8,300 to 17,00.

[ Experimental example 3]

A cosmetic composition was prepared using the same method as in Preparation Example, but three types of samples of the aqueous phase were prepared, the viscosities of the aqueous phase were 8,000 cP, 13,200 cP, and 17,400 cP, respectively, and the viscosity of the oil phase was 28,000 cP, 32,000 cP, and 35,000, respectively. Five types of samples of cP, 38,500 cP, and 43,000 cP were prepared and each was combined to prepare 15 combinations of samples.

At this time, the contents of the aqueous thickener and the oil-based thickener were changed to form the viscosity, and the contents of purified water and moisturizing oil were changed respectively according to the addition or subtraction of these thickeners, so that the content ratio of the aqueous moisturizer and the additive in the aqueous phase and the content of the oil in the oil phase were changed. The content ratio of the pigment and the capsule former was kept constant.

Next, for each sample, the formulation was observed in the same manner as in Experimental Example 2, and the results are shown in Table 5.

In addition, each sample was applied to the lower arm for 20 subjects aged 20-40 years, and the application performance of the cosmetic composition was rated from poor application performance (1 point) to excellent application performance (5 points) using a five-point scale method. were evaluated, and the average value of the results is also shown in Table 5.

The application performance was evaluated based on whether the oil phase part and the water phase part were uniformly mixed and applied smoothly, and whether the capsule shape of the oil phase part was easily broken even with a small force.

Referring to the experimental results in Table 5, it was confirmed that, regardless of the viscosity of the aqueous phase, when the viscosity of the oil phase was 30,000 cP or more, the fine oil formation power and the formulation retention at room temperature were good. However, when the viscosity of the oil phase is less than 30,000 cP, it appears that the formulation in the form of microcapsules is not formed, confirming that the viscosity of the oil phase is preferably 30,000 cP or more. In addition, regardless of the viscosity of the aqueous phase, the viscosity of the oil phase is In the case of 40,000 cP or more, the application performance was evaluated as poor, which is because the viscosity of the oil phase part is excessively high and is formed into a hard microcapsule. It was evaluated that it does not apply smoothly on the skin.

Therefore, from the results of this experiment, it could be confirmed that the viscosity of the oil phase was preferably 30,000 to 40,000 cP, and more preferably 32,000 to 38,500 cP.
