Description

[0001] MAKEUP COSMETIC COMPOSITION WITH WATER IN OIL EMULSION TYPE [0002]

The present invention relates to a water-in-oil type make-up cosmetic composition, and more particularly, to a water-in-oil type make-up cosmetic composition which exhibits usability that varies in three stages of a weak-medium-steel, that is, a feeling of wettability due to fine water rupture, In-oil type make-up cosmetic composition.

Various attempts have been made to overcome the limitations of most conventional water-in-oil type formulations in emulsion type make-up cosmetic compositions.

In terms of consumer convenience, BB cream, a concept that reduces complicated makeup stages, and CC cream, a new concept product that finishes the basic product stage, are also launched. In the case of Cs Cream, the appearance is an emulsified cosmetic composition, but the skin care ingredient content is more emphasized, and it is developed as a product designed to provide basic UV protection effect with moisturizing effect and light makeup effect rather than BB cream It has been widely available as a subdivided product that reflects various consumer needs.

In addition, the concept of skin protection goes one step further in the moisturization of skin care products, and as consumers recognize the importance of anti-aging due to various causes caused by external factors such as ultraviolet shielding and pollutants, This trend is expanding to the development of products that are grafted on.

In the future, it is expected that new products with various concepts emphasizing convenience of consumers will be developed. Among them, one of commercially successful examples is waterdrop type water type, and related products and products are continuously developed. The water drop type is a new type of formulation that has been noticed from the beginning of the development of BB cream in Korea. The water drop type has the same appearance as a general type of water-in-water type. However, when the inner film is made thin and the inner film is thinned, when the physical impact such as rolling motion applied to the skin is applied, It was developed with the purpose of giving. The water drop type was attempted to develop the disadvantage that the conventional make-up product of water-in-oil type is generally more salty than the moisture feeling, and can feel dry due to a large amount of powder components. In general, Consumers were attracted by the use and visual differentiation.

However, since the water drop type often has a problem of lowering stability due to temperature change, the inventors of the present invention have found that it is important to secure stability against the temperature change of the contents while linking with the fresh use of the existing water drop type And thus the present invention has been completed.

In order to improve the functional value of the product by imparting an ultraviolet barrier index, an ultraviolet screening agent is generally included in the emulsified makeup product. In general, an ultraviolet screening agent of an inorganic type and an organic type ultraviolet screening agent of an oil type are mixed in a makeup product.

However, when the content of the inorganic UV blocking agent is high, sedimentation easily occurs due to a high specific gravity difference with the water or oil phase. Therefore, when the emulsion is developed as a emulsion, the stability of the formulation should be considered as the first priority. Due to these technical limitations, it is considered that the makeup cosmetic composition of the water-in-oil emulsion type has basically a limit in which various formulations are difficult to be converted.

In addition, the ultraviolet screening agent should be used in a limited range. However, the effect of the raw material on the input amount is increased, and +, which is a unit of UVA ultraviolet screening effect in Korea, is extended from + The law has been amended to be expressed in units of +. Thus, the relationship between UVA blocking effect and skin aging is revealed through various studies and is recognized as more important than in the past.

Korean Patent No. 10-1678559 discloses a water drop solid type water-in-oil type cosmetic composition containing powder. This patent discloses a powder-containing water drop solid type water-in-oil type cosmetic composition which contains both an aqueous dispersion powder and an oil-dispersed powder to enable makeup effect and sebum control.

Based on this technical flow, the inventors of the present invention have paid attention to a broad spectrum or UVA organic UV-blocking agent having an UVA blocking effect in addition to an inorganic UV-ray blocking agent which has a limitation in conversion of formulations as the input amount increases, And a makeup cosmetic composition in the form of a water-in-oil type having a skin tone correcting effect by a makeup effect.

In order to solve the problem of precipitation when a broad spectrum organic UV blocking agent having UVA and UVB blocking effect or an organic UV blocking agent having UVA blocking effect is applied to a water-in-oil type formulation among the organic UV blocking agents used for an oil component, And the condition was confirmed, and it was applied to the development of high emulsion water - in - oil emulsion makeup formulation. In addition, the present inventors have studied the kind and composition of a water-based component which can overcome the stability deterioration due to temperature change in the composition of the water-based component of the water-in-oil type, thereby securing the stability of the formulation.

The present invention can be applied not only to differentiation of usability of formulations, but also to a makeup product which is widely developed as a water-in-oil type, and can exhibit ultraviolet shielding effect stably even in a small amount of oil phase by applying an organic broad spectrum ultraviolet screening agent And a cosmetic composition containing the same.

In addition, the present invention can provide a UV-blocking effect as well as a skin tone correcting effect by a pigment, obtain a moisturizing effect by a water component contained in a high content, and meet the trend of developing a new formulation And to provide a multi-functional product.

The cosmetic composition of the present invention exhibits spreadability of the same cream as ordinary water-in-oil type makeup cosmetics at the initial stage of skin application. As the rolling progresses, it becomes more and more distinctive because it can visually and tactually feel the moisture feeling finely formed by the inner surface of the merchant augmentor gradually, and in the latter half, it is possible to form a uniform and smooth cosmetic film, And to provide a male makeup cosmetic composition.

In addition, the present invention relates to a cosmetic composition which contains up to about 70% of an aqueous phase component such as water, polyhydric alcohol and sugar alcohols, and which contains a broad spectrum / UVA organic ultraviolet screening agent and an inorganic colorant pigment, And which is excellent in the degree of satisfaction with the skin.

Accordingly, an object of the present invention is to provide a cosmetic composition which realizes new usability which is different from the conventional water drop type high in-oil type water-in-oil type emulsion and changes in three stages and overcomes the stability deterioration of the FT condition which is a disadvantage of the water drop type will be. At the same time, by studying the composition of the oil phase which can stably carry the broad spectrum organic UV-blocking agent on the trauma so as to ensure long-term stability and at the same time to have an excellent ultraviolet blocking effect.

The water-in-oil type make-up cosmetic composition of the present invention initially spreads to soft usability similarly to the general water-in-water type. However, as the rolling progresses, the inner aqueous phase component is finely blown out, and moist feelings can be visually confirmed. In the step, it is uniformly finished with soft usability with an adherence feeling, and usability changes in three stages. The cosmetic composition of the present invention is highly satisfactory in terms of skin expression, moisturizing properties, and toilet paper properties, and is free from deterioration of emulsion stability due to temperature change.

FIG. 2 is a photograph (left) of a water-in-oil type makeup cosmetic composition according to the present invention and a photograph (right) in which water of fine particles is blown out when the composition is applied while being rolled.
3 is a graph showing the skin tone retention ratio (%) of Example 5 (1) according to the present invention and Comparative Example 5 ().

The high inland water-in-oil type makeup cosmetic composition according to the present invention includes a water-based component, a silicone-based nonionic surfactant, an inorganic pigment, an organic ultraviolet screening agent, and a oily emollient.

Specifically, the cosmetic composition preferably contains 55 to 70% by weight of a water-based component, 1 to 5% by weight of a silicone-based nonionic surfactant, 5 to 10% by weight of an inorganic pigment, 1 to 15% by weight of an organic UV- %, And emulsion emollient 10 to 20 wt%. In the above, the water component is composed of purified water and a water-soluble moisturizer, and the moisturizing agent is 55 to 70% by weight of a polyol, a water-soluble polysaccharide and a mixture thereof. It is preferable that the water component is 55 to 70% by weight based on the total weight of the cosmetic composition.

When the content of the water phase component is less than 55% by weight, when the content of the inner phase component is lowered in the water-in-oil type, viscosity not more than a certain level important for formation of the formulation stability is not formed. The usability that changes to the third level does not appear.

When the content of the water phase component is more than 70% by weight, the inner phase content becomes excessively high during the emulsification process in the manufacturing process, so that excessive viscosity is formed and the uniform physical shearing force of the emulsification device is not transferred. It may not be uniform. If the emulsified state of the emulsion is not uniform, it is difficult to change the usability and secure the stability of the formulation for a long period of time.

The water-in-oil type make-up cosmetic composition of the present invention can be used as a water-soluble moisturizer, such as glycerin, diglycerin, butyleneglycol, propylene glycol, hexylene glycol, pentylene glycol, dipropylene glycol, propanediol, sorbitol, Lys-26, isopentyldiol, and methylpropanediol as essential components. The ratio of purified water and water-soluble humectant is preferably from 2: 1 to 1: 1. When the ratio of the purified water and the water-soluble moisturizer exceeds 2: 1, the stability of the formulation due to the temperature change may be deteriorated. Particularly, in the case of low viscosity polyol component such as butylene glycol, which is a typical component of water-soluble humectant, freezing point (° C) is mostly below -40 ° C., and as the content thereof increases by a certain amount or more, stability at a severe condition such as F / Respectively. When the ratio of the purified water and the water-soluble moisturizer is less than 1: 1, the usability of the moisturizing agent becomes excessively strong, which may cause specific stickiness, and the viscosity of the moisturizer may be reduced and the stability of the formulation stability may be deteriorated.

The cosmetic composition of the present invention preferably contains a silicone-based nonionic surfactant in an amount of 1 to 5% by weight based on the total weight of the cosmetic composition. The silicone-based nonionic surfactant is an emulsifier widely used in water-in-oil type makeup cosmetic compositions. Silicone-based components, which are the basic structure, are silky and lightly usable. In addition to silicone backbones, hydrophilic and lipophilic functional groups are additionally applied. It is generally used because it has excellent emulsifying power because there are many products considering the compatibility between various kinds of oils used.

When the silicone-based nonionic surfactant is contained in an amount of 1% by weight or less, the emulsifier content is so small that it can not stably emulsify and impregnate the aqueous phase component and can not stably stabilize the oil phase and water phase during manufacture due to the shortage of emulsifier. When a silicone-based nonionic surfactant is used in an amount of more than 5% by weight, a uniform emulsion such as a general water-in-oil emulsion type can be obtained and the inherent usability of the present invention is lost. In other words, there is no tactile and visual expression process of the moist moist feeling in the middle of application, which is the most characteristic part of the three-stage change step inherent to the present invention.

The silicone-based nonionic surfactant is preferably Cetylpiperazine / Pipi-10/1 Dimethicone. Cetylpiperazine / Pipi-10/1 Dimethicone is a lipophilic emulsifier. Among the silicone emulsifiers used in emulsifying makeup, , Safety and compatibility with other organic materials. Dimethicone is capable of producing stable emulsions even in a small amount, and is less susceptible to skin irritation due to high emulsifier usage, and since it is based on silicon in view of usability, It is advantageous to obtain a usable emulsion which is relatively silky and less sticky.

The in-water type makeup cosmetic composition of the present invention is characterized in that the inorganic pigment is at least one selected from the group consisting of titanium dioxide, zinc oxide, yellow iron oxide, red iron oxide, black iron oxide, ultramarine blue, ultramarine pink, ultramarine violet and chromium oxide green ≪ / RTI > as an essential ingredient. The cosmetic composition of the present invention preferably contains an inorganic pigment in an amount of 5 to 10% by weight based on the total weight of the cosmetic composition. When the content of the inorganic pigment is 5% by weight or less, an appropriate skin tone improvement effect due to the coloring material component including the white pigment can not be obtained. In the case where the content of the inorganic pigment is 10% by weight or more, the phase in which the powder coated with the hydrophobic component is dispersed due to the nature of the water-in-oil type formulation is an external phase which is a foreign matter. So that uniform dispersion is difficult, and as a result, emulsification is not uniformly performed, resulting in a decrease in the stability of the formulation.

The cosmetic composition of the present invention contains a broad spectrum / UVA ultraviolet screening agent and a UVB ultraviolet screening agent as essential components as an ultraviolet screening agent.

The broad spectrum / UVA ultraviolet screening agent is a mixture of at least one selected from the group consisting of bis-ethylhexyloxyphenol methoxyphenyltriazine, diethylaminohydroxybenzoylhexylbenzoate and butylmethoxydibenzoylmethane.

The UVB ultraviolet screening agent may be at least one selected from the group consisting of ethylhexylmethoxycinnamate, isoamyl p-methoxy cinnamate, ethylhexylsalicylate, polysilicon-15, octocrylene and 4-methylbenzylidene camphor / RTI >

The organic UV-blocking agent of the present invention is preferably 1 to 15% by weight based on the total weight of the cosmetic composition. When the content of the organic UV blocker is less than 1% by weight, it is difficult to obtain UVA and UVB values, which are suitable UV blocking factors.

When the content of the organic UV-blocking agent is 15 wt% or more, the content of the remaining oil contained in the oil-in-water emulsion is limited in the case of the high inland water-in-oil type water-in-oil formulations of the present invention. Thus, the broad spectrum / UVA ultraviolet Precipitation phenomenon may occur in terms of long-term stability due to the limitation of the solubility of the blocking agent, or it may be difficult to secure the stability of the emulsion due to the characteristics of the organic UV-blocking agent having a high polarity.

The in-water type makeup cosmetic composition of the present invention may contain a broad spectrum / UVA ultraviolet screening agent and a UVB ultraviolet screening agent as organic-based ultraviolet screening agents at a weight ratio of 1: 2 to 1: 3.

If the weight ratio of the broad spectrum / UV ultraviolet screening agent to the UVB ultraviolet screening agent is less than 1: 2, the content of the UVB ultraviolet screening agent, which is the main solvent of the broad spectrum / UVA ultraviolet screening agent, becomes small.

When the ratio of the broad spectrum / UVA ultraviolet screening agent to the UVB ultraviolet screening agent exceeds 1: 3, the appropriate value of the UVA blocking index, the PA value, is not obtained and the ratio of the UVA value and the UVB value is not matched. Can not be done.

The in-water type make-up cosmetic composition of the present invention contains an oil-based emollient as an essential ingredient.

The hydrocarbon-based compound may be selected from the group consisting of mineral oil, hydrogenated polydecene, hydrogenated poly (C6-14 olefin), hydrogenated polyisobutene, squalane, isohexadecane, isoparaffins, petrolatum, Microcrystalline wax, or a mixture thereof.

Examples of the ester oil include propylene glycol dicaprylate / dicaprate, dicaprylyl carbonate, isodecyl neopentanoate, butyleneglycol dicaprylate / dicaprate, hexyl laurate, phenethyl benzoate, C12- 15 alkyl benzoate, neopentyl glycol deptanoate, butyl octyl salicylate, or a mixture thereof.

The oil gelling agent may be any one selected from the group consisting of tribehenin, glyceryl behenate / eicosadioate, glyceryl tribehenate / isostearate / eicosan dioate, or a mixture thereof.

The oily emollient is preferably 10 to 20% by weight based on the total weight of the cosmetic composition. When the content of oily emollient is 10 wt% or less, the usability of the cosmetic composition of the present invention, in which the ratio of oil phase to water phase is appropriately expressed, is not realized. In addition, wetting of the inorganic powder pigment dispersed in the oil phase is not sufficient and the dispersibility becomes poor, which causes the stability of the emulsion to be degraded. In addition, the solubility of the solid organic UV blocking agent, which is dissolved in the oil phase and emulsified in a liquid state, is lowered, and precipitation may occur during long-term stability observation.

When the content of oily emollient is 20 wt% or more, the usability of the cosmetic composition of the present invention, in which the ratio of oil phase to water phase is expressed only under appropriate conditions, is similarly not realized. That is, if the content of the emulsion is increased under the condition that the covering force is maintained, the content of the water component is reduced. It is expected that the stability of the formulation due to the drop in viscosity is expected due to the nature of the water-in-oil type in which the water content is closely related to the viscosity.

In addition, the oily emollient is composed of a hydrocarbon compound, an ester oil, and an oil gelling agent, and may be contained at a weight ratio of 1: 6: 1. If the ratio of the ester-based oil is reduced or the hydrocarbon-based compound is elongated, the content of the oil serving as the main solvent is decreased as a result of compatibility with the polar organic UV blocking agent, and the precipitation phenomenon may occur when the stability is observed for a long period of time. When the content of the hydrocarbon-based compound is reduced or the content of the ester-based oil stream is increased, the three-stage usability which is unique to the present invention, which maximizes the polarity difference between the oil phase and the water phase, does not appear. That is, the moisturizing feeling and the fine water burst phenomenon appearing as the rolling progresses do not appear, which is considered to be related to the properties of the oiling sieving membrane of the present invention formed by including the oil component having a non-polar nature at a certain ratio or more. The oiling sieving film which collects a relatively high distribution water phase shows soft oil spreading at the beginning of the application in which light rolling (physical impact) is progressed. As the rolling progresses, the inner water phase slowly escapes, This makes it possible to express sensible and visually identifiable moisture in the stage prior to complete mixing with the screen by physical force. For this reason, if the hydrocarbon-based compound having a non-polar property is contained in a certain amount or more, the characteristic usability of the cosmetic composition changing to the three-step of the present invention can be exhibited.

In addition, since the oil gelling agent has a role of the oil gelling agent applied to the water-in-oil type formulation and has a compatibility with the oil of the trauma, and at the same time, it gels at the room temperature, and the stability of the formulation is structurally improved. Structural stability can be improved, but the use of the gelling agent is emphasized, and the change in the structural properties can affect the usability of the formulation in three steps. When the content of the gelling agent is reduced, the stability is deteriorated easily due to the temperature change, which is a general disadvantage of the high water-in-oil type water-based formulation, adversely affecting formation of a stable structure.

In order to achieve the object of the present invention, which is to provide a makeup cosmetic material with a high in-oil-in-water type which is capable of simultaneously imparting ultraviolet shielding effect and makeup effect while exhibiting usability different from that of a water drop type, Using the basic formulation of a water-in-oil type containing an organic filter of the daily sunscreen product level, the implementation of the usability and the conditions of use of the stabilized sunscreen agent were studied and applied to the examples.

In the present invention, it has been found that the above-mentioned raw materials can contribute to the improvement of stability when they are mixed or substituted with the components of the existing prescription, and a new prescription is formed to confirm its performance.

Other objects and advantages of the present invention will become more apparent from the following detailed description and claims.

Experimental Example 1: Comparison of stability of organic sunscreen agent according to the kind of softener

The makeup cosmetic composition of the present invention is a formulation containing an ultraviolet screening agent, and in particular, an organic ultraviolet screening agent is included in an oily phase which is a foreign body. The purpose of the sunscreen is to protect the skin by blocking UVA and UVB. Especially, the makeup products are used in the final stage after applying the base product. Many products in Korea and abroad have been using makeup products such as foundation products And SPF and PA index. Consumers' needs for skin protection, which started from changes in the natural environment, have been greatly increased. The importance of the ultraviolet screening effect has been emphasized. At first, the ultraviolet screening effect was mainly focused on the UVB screening effect. And is recognized as an essential element. Although the product has been developed as a single product, it is becoming a functional combination with makeup and basic products. In the case of daily products, the SPF30 or higher is recognized as a suitable level for skin protection.

Accordingly, the present inventors have recognized that it is important to secure the stability of a broad spectrum or UVA ultraviolet screening agent, which exists in a solid form at room temperature, in order to apply an organic ultraviolet screening agent to general emulsified makeup products. In order to ensure stability when solid organic UV blocking agents are present, prior studies prior to the formulation studies were carried out to compare the amount and the amount of precipitation phenomenon with respect to the amount of UV absorbing agent based on the amount of UV blocking agent.

In Experimental Examples 1 to 3, a broad spectrum organic UV-blocking agent and UVB organic UV-blocking agent according to the present invention were prepared by mixing an ester-based oil with a sample having a mixing weight ratio of 1: 2.5. At this time, the ester-based oil and the broad spectrum organic UV-blocking agent were added at a ratio of 1: 3.

Comparative Experimental Examples 1 and 2 are samples having a mixture weight ratio of isodecyl neopentanoate and an alkyl-added silicone oil outside the scope of the present invention. As a solid type organic UV-blocking agent, 12% of bis-ethylhexyloxyphenol methoxyphenyltriazine (solid at room temperature), an organic UV blocking agent having excellent UV UVA and UVB blocking ability, was dissolved in a liquid organic UV blocking agent, ethylhexylmethoxy And 30% of cinnamate were mixed at the same ratio as the basic structure, and the low temperature stability was compared by further mixing the ester oil.

Each of the samples was treated in the same manner as in Example 1 except that the mixing ratio of the final oil was the same, and the mixture was warmed to a temperature of 80 to 85 DEG C of bis-ethylhexyloxyphenol methoxyphenyltriazine to prepare a liquefied sample. The samples were stored under freezing conditions of minus 20 ° C to confirm the low temperature stability of the samples. After 12 months, the precipitation of bis-ethylhexyloxyphenol methoxyphenyltriazine was confirmed.

As shown in the results of Table 1 and Table 2, it can be seen that there is a difference in solubility depending on the type of oil in which the ultraviolet shielding component is dissolved. That is, in the case of the organic UV-ray shielding component which is solid at room temperature, the stability of the formulation upon long-term low-temperature exposure is influenced and the stability may be deteriorated in the form of precipitation. Experimental Examples 1 to 9 In the case of the ester oil contained in the ester oil, it was confirmed that the organic UV blocking agent in the form of solid at room temperature was dissolved in the condition of the melting point or higher and was stable without being precipitated even under long-term low temperature conditions (Table 2).

Based on the results of the test for improving the precipitation stability of the ultraviolet screening agent of the Experimental Example, a prescription experiment was conducted on the cosmetic composition of the present invention.

Hereinafter, the present invention will be described in more detail with reference to Examples. These embodiments are only for describing the present invention more specifically, and the scope of the present invention is not limited by these embodiments in accordance with the gist of the present invention.

Production Example 1: Determination of Emulsifier Content for Usability Implementation

The high-resistance water-in-oil type cosmetic composition of the present invention is different from the water drop type formulation which is representative of the existing high-resistance water-in-oil type cosmetic composition, and includes three kinds of feeling change including the usability at the time of initial application .

From the formulation point of view, the easiest way to quickly drain and cool my merchant awards is to make the interfacial membrane somewhat thinner, to emphasize the initial bursting of water, as is the case with most of the water drop-type high- . As a result, the amount of the emulsifier, which is a function of forming a homogeneous and stable emulsion by allowing the inner phase water phase to be finely collected, is insufficient, thereby achieving the desired purpose. However, the fact that the amount of emulsifier used is insufficient is a method that can be easily accessed from the aspect of usability, but securing stability is an essential requirement in terms of enhancing value as a product. The storage conditions of the product can be influenced by seasonal changes and transportation conditions. If the temperature change is severe, the stability of the product may appear immediately, which can lead to a consumer claim. It can be seen that the WO water drop type make-up product stored at room temperature exhibits a phenomenon in which water is naturally infiltrated into the surface due to aging (FIG. 1). FIG. 2 shows the makeup cosmetic composition of the present invention in which the usability of the cosmetic composition according to the present invention is changed to three stages. In other words, when the formulation is applied, the water component of the inner phase is slightly blown out as the rolling progresses, and the moist feeling of moisture is tactually and visually confirmed in the early stage. And shows uniformly finished characteristics with usability.

One of the purposes of cosmetic formulation research, which is a product for which the period of use is set, is not only satisfying consumer needs through the implementation of a new usability, but also from the aspect of securing a product power that can be used stably for a certain period of time, It is one of the difficult problems that can not be easily attained even by those skilled in the art, while maintaining usability with property change such as drop type, and securing stability by temperature change.

Therefore, the inventors of the present invention have conducted studies to overcome the stability degradation due to temperature change as well as the implementation of the usability that is similar to the dramatic water burst phenomenon of the conventional water drop type formulation, To thereby make the high-resistance water-in-oil type makeup cosmetic of the present invention.

That is, the change in the three-step usability, which is unique to the high-resistance water-in-oil type make-up cosmetic composition of the present invention, is as follows: 1) it spreads softly like a normal WO emulsified makeup product, 2) it bursts like an essence, 3) The third is characterized by usability (feeling of roughness in the middle) that is soft and softly finished.

In order to realize such usability, the condition of the WO emulsifier which is specialized in formulation of the water drop type formulation is fixed and the condition of the formulation is realized by the amount of the WO emulsifier is confirmed through the following examples.

Whether or not the water-jetting property appeared depending on the emulsifier content in the composition of Table 3 was confirmed. In Examples 1 to 4, the emulsifier content was 1.40 to 2.00 wt%, showing the change in usability in the three-step process characteristic of the cosmetic composition of the present invention. The separation phenomenon of the same day and the Freeze-Thaw condition As a result of the stability test, it was confirmed that the stability of one cycle did not deteriorate.

On the other hand, in Comparative Examples 1 to 3, when the emulsifier content was less than 1.0 wt%, the content of the emulsifier was so small that the appearance of the appearance was unstable because the oil phase and water phase were mixed with each other. In the case of Comparative Example 4, it was confirmed that the emulsifier content was 1.1 wt%, and the change in usability and water rupture occurred in three stages immediately after the production, but it was confirmed that the separation phenomenon such as cracking of the surface was observed immediately on the day of emulsification.

Based on the content of Example 4 of Preparation Example 1, further experiments were conducted to secure the stability by temperature change while keeping the usability of the emulsifier varying from 3% to 2.0% based on the emulsifier content of 2.0%.

Production Example 3. Evaluation of stability

The storage stability of the high inhalation makeup cosmetic compositions of Examples 5 to 8 and Comparative Examples 5 to 8 was tested. Each composition was placed in a transparent container in a volume of 40 g each and incubated at a high temperature (45 DEG C, 60 DEG C), a cold (4 DEG C) thermostat and a cycle test (CT, cycle: once a day at -4 DEG C to 40 DEG C, And 40 [deg.] C for 6 hours), and the change with time was observed. The condition of F / T (frozen / thawed) condition and the storage stability of 60 degrees in severe condition were observed at 1 day and it was observed at room temperature, cold (4 ℃), high temperature (45 ℃) The results of one storage stability test are shown in Table 4 below.

As can be seen from Table 5, Examples 5 to 8 exhibited excellent surface roughness according to the change in temperature. Even after one month of stability observation, the specific usability such as abundant moisture and finishing use remained unchanged as the rolling progressed Respectively. On the other hand, Comparative Examples 5 to 8, in which the ratio of the purified water of the water and the humectant was not 1: 1 or 2: 1, maintained a good condition at room temperature, but did not satisfy all of the refrigeration, And the stability is lowered.

Manufacturing example  4: Feeling , Skin expression and Moisturizing  evaluation

Using Example 5 and Comparative Example 5 having the same amount of the sunscreen agent as the oily component, 20 users were evaluated for their usability and moisturizing properties. The age distribution of the pestle was 25 ~ 45 years old, and after 3 days' daytime application, we compared the quality of rubbing, toilet paper, skin expression, moisturizing power, moisturizing persistence and overall satisfaction. The results of the evaluation are shown in Table 6 below.

Item Example 5 Comparative Example 5 Brittle 4.0 3.8 Toilet paper property 4.0 3.8 Skin expression 4.0 4.0 Moisture power 4.1 3.7 Moisture persistence 4.2 3.6 Overall satisfaction 4.2 3.8 <Rating> 4.5 out of 5

As shown in Table 6, the makeup cosmetic composition of Example 5 is superior to Comparative Example 5 in evaluation items of toilet paper properties, moisture resistance, moisturizing persistence, and overall satisfaction excluding skin expression.

In the case of the rinseable items, the evaluation was made based on the change in the three-step usability, which is unique to the high-resistance water-in-oil type cosmetic composition of the present invention. That is, it spreads softly on the first application, bursts like a second essence, spreads moist, and is characterized by usability (weak-medium-ripe feeling) that is finished soft and softly. Example 4, in which such usability was realized, was rated superior to Comparative Example 2. This can be said to be related to the fact that most of the water drop type formulations have a prescription characteristic that seeks for light use and moisturization of the silicone oil base and emphasize the tight fitting feeling required for makeup products and the usability that remains moist after application have. The high inland water-in-oil type cosmetic composition of the present invention was developed by excluding the silicone oil in addition to the emulsifier to improve the stability with the organic ultraviolet screening agent while realizing the usability different from the water drop type.

Particularly, in Example 5, 30% by weight of butylene glycol was used as a moisturizer, and a moisturizing component was contained in a large amount.

In the case of the toilet paper attribute item, it is related to a component such as titanium dioxide contained as a pigment for skin tone correction, unlike the basic formulation, due to the characteristics of the emulsifying makeup formulation including the inorganic pigment. The makeup cosmetic material containing the inorganic powder component may evaporate moisture as time elapses after application, resulting in skin dryness and make-up lifting, as well as wrinkles and cracking due to drying of the cosmetic film. Therefore, in developing emulsifying makeup formulations, besides external factors such as covering power and skin expression, evaluation of the moisturizing effect imparted by the balance effect between the oil component and the moisturizing component may be an important evaluation factor.

In the case of Example 5, the moisturizing component content was 30% by weight, which was three times higher than that of Comparative Example 5, and the moisturizing property was maintained for a relatively long time while applying the makeup. It can be assumed that it is reflected in satisfaction.

Manufacturing example  5: Makeup persistence evaluation ( Skin tone  Calibration and maintenance)

The skin brightness was measured with Spectrophotometer CM-600d from both balls of 20 subjects, and the makeup cosmetic materials of Example 5 and Comparative Example 5 were applied to both balls. After the application, the skin brightness was measured using Spectrophotometer CM-600d after 0, 2, 4, 6, 8 hours, and the make-up persistence (skin tone correction and maintenance) was confirmed. The results are shown in Table 7 and FIG.

The skin brightness before and after the application of Example 5 and Comparative Example 5 were measured using a spectrophotometer. As a result, the values L and L of the skin brightness of Example 5 and Comparative Example 5 were increased by 2.1 and 1.3, respectively. It was confirmed that the makeup cosmetic composition of Example 5 was superior to the cosmetic composition of Comparative Example 5 in the effect of correcting the skin tone.

After the cream of Example 5 and Comparative Example 5 was applied, the change of skin tone over time was checked. As a result, the retention ratio of the product of Example 5 and the product of Comparative Example was 43% and 31%, respectively, It was confirmed that Example 5 was superior.
