Hereinafter, the present invention will be described in more detail with reference to the powder coating preparation method and the two-layer separation type cosmetic preparation technique, which are excellent in water repellency and water dispersion, as a key part of the present invention.

1. Primary coating method of composite powder

First, as a method for producing powder coating powder capable of dispersing water with excellent water repellency, it can be carried out by a wet method and a dry method by a method of first coating with a polysaccharide on the surface of a composite powder. The composite powder used in the present invention is typically titanium dioxide, silica, talc, and mica, which can improve the feeling of use, cover function, and ultraviolet ray blocking function.

Specifically, titanium dioxide having a particle size of 100 to 300 nm is used to easily disperse in water and can be easily settled. In order to prevent sedimentation and hardening even if settled, it has a particle size in the range of 3 to 50 μm and a surface area of 300 Porous silica having a pore size of from 1 to 1,000 m < 2 > / g and from 3 to 50 nm can optionally be used. A mica of similar size to talc of 1 to 50 μm can also be used.

More specifically, it is possible to use titanium dioxide in an amount of 150 to 250 nm, a particle size in the range of 10 to 30 μm and a surface area of 400 to 700 m ² / g, a porous silica having a hole of a size of 5 to 40 nm, a talc of 10 to 40 μm, Can be used. The manufacturing method is shown in detail in Fig. The used concentration includes any one of 20 to 80% by weight of titanium dioxide, 1 to 30% by weight of porous silica, 1 to 30% by weight of talc, and 1 to 30% by weight of mica based on the total weight of the composite powder , Or a mixture of any combination thereof. More specifically, it includes any one of 30 to 70% by weight of titanium dioxide, 5 to 20% by weight of porous silica, 5 to 20% by weight of talc and 5 to 20% by weight of mica based on the total weight of the composite powder , Or a mixture of any combination thereof.

As shown in FIG. 1, the composite powder described above is weighed by a primary coating method, and 0.1 to 10% by weight, based on the total weight of the composite powder, of polysaccharides of 100,000 to 300,000 dalton 10 to 50% by weight of ethanol is mixed with 30 to 70% by weight of water, mixed with the powder, and dispersed by stirring at 500 to 1,500 rpm to prepare a slurry. The slurry is transferred to a drier and dried at 90 to 150 ° C., And crushed with a Henschel mixer and an atomizer to obtain a fine primary coating powder. As a result of the first dispersing experiment, it was found that sedimentation occurred well when dispersed in water phase, but when stored for a long period in a sedimented state, it hardly hardened and was not easily dispersed when shaken. There was no significant effect on the range of about 1 to 2 weeks, but when the powder was allowed to stand for 3 weeks or more, particles and particles were entangled to each other and the composite powdery powder required in the present invention could not be obtained. In addition, the feeling of use was very sticky, and water repellency and ultraviolet ray blocking effect could not be expected, so that a proper quality could not be obtained as a cosmetic product. Therefore, in order to solve this problem, a secondary coating process described later is performed.

2. A method of secondarily coating a fluorine-based oil compound having water repellency to a composite powder

In the present invention, the fluorine-based oil derivative is coated on the outermost layer so that it can be mixed with the hydrophilic system having the desired performance and have water repellency. A schematic diagram designed to develop a superior feel and stable coating as a cosmetic product is shown in Fig.

FIG. 2 is a schematic diagram for easily describing the dispersion of the powder by coating the composite powder with a polysaccharide and coating the outermost surface of the coating product with a fluorine-based oil to prevent coalescence among the powders. When doing this, high water repellency and durability can be expected. In addition, FIG. 3 shows a technical schematic diagram of a preparatory form so that a detachable skin foundation or a detached type skin makeup base and a skin cleanser can be developed. The upper part of FIG. 3 is a skins having a basic cosmetic function, and the submerging lower part is a composite powder part, and a differentiated product having a makeup base, a foundation, and a cream having a creamy function can be developed. Therefore, it is possible not only to have differentiation of products, but also to develop multifunctional products that are fused without distinguishing between base and color cosmetics.

First, by coating the first polysaccharide-coated powder with polyperfluoromethylisopropyl ether, fluoroethoxymethoxydifluoroethyl PEG-phosphate, and perfluorotecarin, it is possible to disperse the water, . The fluorine-based oil as the secondary coating material is preferably 0.01 to 10 wt% of polyperfluoromethyl isopropyl based on the total weight of the composite powder, 0.01 to 5 wt% of polyperfluoroethoxymethoxy difluoroethylene PEG -Phosphate, and 0.01 to 5% by weight of perfluorodecalin, or a mixture of any combination thereof. More specifically, 0.1 to 3 weight% of polyperfluoromethylisopropyl is added to the total weight of the composite powder, 0.1 to 3 weight% of polyperfluoroethoxymethoxy difluoroethylene PEG-phosphate, Perfluorodecalin may be used alone or as a mixture of two or more thereof in an amount of 0.1 to 3% by weight. In the present invention, the present inventors have experimented with a practical optimum composition considering economic efficiency and efficiency.

In a concrete manufacturing method, 1 to 5% by weight of polysaccharide is coated on the surface of the composite powder by first spraying the same on the total weight of the composite powder, dried in a dryer at 70 to 120 ° C under reduced pressure, The resultant was dried under reduced pressure at 80 to 120 ° C while spraying a mixture of 0.1 to 5 wt% of polyperfluoromethyl isopropyl ether and 5 to 30 wt% of ethanol solution to the total weight of the composite powder to obtain 2 After coating with tea, it is put in a dispersing blender and injected while spraying while rotating. It is dried in a dryer at 70 to 120 ° C to remove the ethanol solvent, and can be pulverized with a Henschel mixer and an atomizer. For example, 0.1 to 5% by weight of polyperfluoromethylisopropyl isocyanurate is mixed and dispersed finely in an ethanol solution to a composite powder coated with 1 to 5% by weight of polysaccharide, and then the mixture is dispersed in a dispersion mixer, And then further dispersed for 5 to 20 minutes so that sufficient adsorption can be made on the surface of the composite powder. This is put into a dryer, for example, the temperature is adjusted to 70 to 90 ° C, and the ethanol solvent is removed by decompression. This is ground with a Henschel mixer and an atomizer to form a finely dispersed powder composite coated with a fluorine-based oil. Further, a large amount of ethanol, water and a fluorine-based oil are mixed and sufficiently dispersed in a slurry form together with the mixed powder, then coated on the surface of the powder, dried at 90 to 150 ° C, And an atomizer to prepare a fine powder coated with a fluorine-based oil.

The results of measuring the specific gravity of the fluorine-coated powder coating powder are shown in Table 1 below.

[Table 1]

As shown in Table 1, the specific gravity of non-pigmented white powder was measured. The specific gravity of the uncoated powder was 1.02 ± 0.1, and the specific gravity of the polysaccharide-coated sample was 1.08 ± 0.2 and that of the powder coated with fluorine-based oil was 1.39 ± 0.2. , And the colored powder was also increased depending on the coating.

The powder coating powder for a cosmetic composition of the present invention can be produced by the above-described method for producing a powder coating powder for a cosmetic composition according to the present invention.

Also, the cosmetic composition of the present invention may include a powder coating powder prepared by the above-described method for producing a powder coating powder for a cosmetic composition according to the present invention. For example, To 30% by weight of an aqueous solution containing 1 to 20% by weight of glycerin, 1 to 10% by weight of butylene glycol, 0.1 to 5% by weight of betaine, 30 to 70% by weight of purified water, 0.01 to 0.1% 0.1 to 5% by weight of arbutin, and 0.1 to 5% by weight of niacinamide. Thus, the upper layer may be separated into a two-layered form with the skin layer and the lower layer being powdered. Herein, adenosine, arbutin, and niacinamide corresponding to the additives may be, for example, 0.04% by weight, 2% by weight and 2% by weight based on the total weight of the cosmetic composition.

Another example of the cosmetic composition of the present invention is a cosmetic composition comprising 5 to 30% by weight of the powdery coating powder based on the total weight of the cosmetic composition, 10 to 50% by weight of cyclopentasiloxane, 2 to 10% 1 to 10% by weight of dimethicone and 0.01 to 0.1% by weight of fragrance, so that the upper layer may be separated into a two-layer form in powder phase and the lower layer.

3. Sedimentation and Dispersibility Evaluation

In the present invention, when dispersed in an aqueous phase, it is possible to easily disperse and precipitate easily. The result of primary coating with a polysaccharide for long sedimentation, Acidity was measured. The measurement samples were evaluated on Examples 1 and 2 and Comparative Group 1 of Table 3 to be described later. The results are shown in Table 2 below. As shown in Table 2, the microdispersed powder was in poor condition in all respects. In the case of coating with only polysaccharide, the water dispersion state, sedimentation and separation were good, but the redispersibility was not so good. However, in the case of the powder of the double coated powder of Example 2 of the present invention, it was found that the powder was well separated and dispersed and settled well under all conditions.

[Table 2]

Various formulations with basal and toning functions are shown in Fig. FIG. 4 shows three inventions in which various formulations were actually developed using Example 2. FIG. Invention 2 of the invention is a two-layer detachable formulation having a base make-up function while having a moisturizing function of a skin toner. Inventive Item 3 has a skin tone control function The formulations in which the formulations capable of correcting the functions and defects are shown as representative examples.

4. Development of cosmetic application prescription

Table 3 shows the emulsions that can have make-up functions while having skin-care functions as an application prescription for cosmetics.

[Examples 1 to 4, Comparative group 1]

[Table 3]

As shown in Examples 1 to 4 and Comparative Group 1, a cosmetic composition having a skin foundation function was prepared by two-layer separation.

As a production method thereof, as shown in Table 3, the phase (B) is dispersed in a disperser at 100 to 1500 rpm so as to be sufficiently dispersed on the phase (A), and then the phase (C) is added and sufficiently solubilized. Finally, (D) phase is slowly added to disperse the powder well. When this is allowed to stand for 24 hours, the makeup layer is held in the upper layer, and the powder is held in the lower layer, and the production is completed. In Examples 2, 3 and 4, the prescription group using the double coating powder (present invention) formed a more stable sedimentation than the other two prescriptions and easily dispersible when shaken. In Example 1 and Comparative Group 1 It was easy to disperse, but when shaken over time, it hardened hard and did not shake well. Fig. 5 is a photograph showing the dispersion state when shaken and the dispersion state when left for 2 hours for a prescription made by coloring with pigment pigment in Example 4. Fig. As can be seen from the photographs, when shaken, it is in a well-dispersed state with a skin-colored form, and after 2 hours from the start of the settling, it is clearly divided into upper and lower layered formulations. This photo shows a very special formulation with characteristic features. The fundamental reason for inventing this product was that the formulations of Bibby Cream and Foundation Cream were more than 90% W / S or W / O formulations when examining the patterns of use of color cosmetics in Korea as well as Southeast Asian women. It is excellent in water repellency, but it expects to get good response to unused women because of oxygen supply of skin, rejection in hot fats and negative aspect.

 5. Clinical trial results

It is a step that verifies the efficacy effect. By verifying step by step moisturizing effect, wrinkle improving effect, skin whitening effect, sebum control effect, ultraviolet shielding effect, skin coverage effect and defective cover effect on the two- This study was conducted to develop a coating agent having a new function that has a skin care effect and a makeup effect.

5.1 Water Repellency Evaluation

The water repellency was measured in Examples 1 and 3 and Comparative Group 1. The measurement method was as follows: a square of 2 cm in width and 2 cm in length was applied to both lower and upper forearm, 0.3 mg of each sample was homogeneously applied, and then immersed in water and repeatedly withdrawn to collect the remaining amount after 3 hours, Were measured. The results are shown in Fig. As shown in the results, the water-repellent effect of the polysaccharide-treated powder was 12%, but in the uncoated comparative group 1, the water-repellent effect was 5% . On the other hand, it was found that the sample of Example 3 of the present invention had a water repellency of 85%. This is a result of demonstrating that by coating the surface of the powder with a fluorine-based oil, it increases the covering power and has the effect of not getting rid of water or sweat in the product.

5.2 Prescription of an Example Having a Wrinkle-Reducing Effect with a Moisturizing Effect

The results of clinical evaluations of the moisturizing effect of Examples 1 and 2 and Comparative Group 1 are shown in FIG. In the clinical study, 10 subjects in their 20s and 50s were included in the study. The measurement method was the same as the skin moisturizing method which is generally used by fixing a certain point of both upper arms and lower arms. As shown in Fig. 7, in the case of the moisturizing effect after 8 hours, the same results were obtained in the untreated group 1 and the comparative group 1 in the same manner as in the untreated group 23%. On the other hand, the moisture retention in Example 2 was 32%, which was much higher than that before application. This result shows that the powder coating powder having water repellency is used, so that it is possible to consider that the water retention ability is maintained without evaporation of water due to the effect of the water repellent powder after application.

[Example 5, Comparative group 2]

The formulation of the example having a moisturizing effect and a wrinkle-improving effect is shown in Table 4 below and in Example 5 and Comparative Example 2. Glycerin and butylene glycol were used as basic moisturizing agents, and 0.04% by weight of adenosine was used as a typical wrinkle remover.

[Table 4]

Especially, when using double coating powder, wrinkle improving effect was much better than the comparative group. The reason for this is that the water-repellent powder has excellent effect on the skin application power and persistence.

Clinical results for wrinkle evaluation with Example 5 and Comparative Group 2 are shown in Fig. For the wrinkle - improving effect, 0.04% of adenosine was used. In comparison group 2, the wrinkle improving effect was about 3%, which was not significant. In the case of Example 5, however, it was found through the clinical trial that the effect of the wrinkle improvement was improved by 23% than that before use. Above all, it is considered possible because it is a formulation that combines basic cosmetic function and color cosmetic function.

5.3 Prescription of an example having a moisturizing effect and whitening effect

[Examples 6 to 7, Comparative group 3]

Prescriptions with a moisturizing effect and whitening effect are shown in Table 4 below and in Comparative Examples 3 and 7 in Examples 6 and 7. Glycerin, butylene glycol and betaine were used as basic moisturizing agents, and 2 wt% of niacinamide and 3 wt% of arbutin were used as typical whitening ingredients.

[Table 5]

Especially, the use of double coating powder in this prescription resulted in a much better whitening effect than the comparative group. The results are shown in Fig. As shown in FIG. 9, the results of Examples 6 and 7 were found to have a whitening effect of 27.8% and 22.5%, respectively, compared with 3.7% of the control group. The reason for this is that the water repellent powder having excellent covering power is excellent in the application power and persistence of the skin.

5.4 Prescription of an example having an ultraviolet screening effect while having sebum control effect

[Examples 8 to 9, Comparative group 4]

Prescriptions having a sebum control effect and ultraviolet screening effect are shown in Examples 8 and 9 and Comparative Group 4 in Table 6 below. Glycerin and butylene glycol were used as basic moisturizing agents, and a dual coating powder (present invention) was used as a representative main effect ingredient.

[Table 6]

Fig. 10 shows evaluation results of the skin control effect in Examples 8 and 9 and Comparative Group 4. In Example 8 using 15 wt% of the double coating powder, 26.2% and 38.8% of sebum was used when 25% was used. However, in Comparative Example 4 using 25 wt% untreated powder, the effect was improved to 15.7% as compared with before use. In terms of sebum control, composite powders can be considered to have an effect on high content usage. As seen from the results, when using the dual coating powder, not only the sebum control effect was excellent but also the ultraviolet ray blocking effect was expected to be much better than the comparative group, and the ultraviolet ray blocking effect was also measured. Fig. 11 shows the results of measurement on the ultraviolet blocking effect. Examples 8 and 9 and Comparative group 4 were used to evaluate the ultraviolet blocking effect test results. Example 8 using 15 wt% of the double coating powder was 32.5, and SPF effect using 25 wt% was 41.2, which was significant. However, Comparative Example 4 using 25 wt% untreated powder showed a 15.7 ultraviolet blocking effect. It can be considered that the powder having water repellency exhibits a high effect in the embodiment of the present invention because it shows excellent effect on the skin application power and persistence.

5.5 Prescription of an embodiment having a cover effect and having a defective cover effect

[Examples 10 to 11, Comparative group 5]

 The prescription to cover the defects while having a covering force is shown in Examples 10 and 11 of Table 7. Glycerin, butylene glycol, and betaine were used as basic moisturizers. As a representative main effect ingredient, the double coating powder (invention) was used as it is. Other ingredients were not used as much as possible to make efficacy assessment clear.

[Table 7]

Fig. 12 shows the result of the coverage test using Example 11 and Comparative Group 5. Fig. In Example 11, when 30 wt% of the double coating powder was used, Comparative Example 5 was the result of testing the covering power using 30 wt% uncoated powder. Example 11 exhibited coverage and skin-to-skin tones, but in the comparative group, a skin tone different from that of the skin was developed with whitening. Therefore, in the present invention, the masking effect of the covering force or the defect having the skin care effect is far superior to that of the comparative group. The reason for this is that it is a water-repellent powder that can be dispersed in the hydrophilic part and exhibits excellent effects on the skin application power and persistence.

5.6 Prescription of an example having moisturizing power and skin barrier strengthening effect

[Example 12, Comparative group 6]

The formulation for the TEWL, which has a moisturizing power and strengthens the skin barrier, is shown in Example 12 and Comparative Example 6 in Table 8 below. As a basic moisturizing effect, glycerin, butylene glycol and betaine were used. As a representative main effect ingredient, 40 wt% of a double coating powder (present invention) was used. 0.01 to 2.0 wt% of sodium chloride and 0.01 to 3.0 wt% of calcium chloride were appropriately used in order to further improve stability of dispersion. More specifically, the use of 0.1 to 1.0% by weight of sodium chloride and 0.1 to 1.0% by weight of calcium chloride can help stabilize the dispersion.

[Table 8]

The evaluation of the light hand skin moisture mass of the basic cosmetic function was tested through the examples and shown in Fig. 10 subjects, ages 20 ~ 50 were applied to the faces of men and women. The measurement was performed in an incubator maintained at 25 ° C using a TEWA meter. 13 shows that the results obtained after 4 weeks and unchanged results were obtained before the application. In Comparative Example 6, the result was mildly low, and in Example 12, there was. A decrease in the amount of light skin moisture loss is a result of demonstrating that the skin barrier is strengthened to that extent.

5.7 Prescription of an example that can be dispersed in oil and separated into two layers

[Examples 13 to 15, Comparative group 7]

The formulations in which the powder coating powder coated in the present invention having water repellency and capable of settling in the oil continuous phase are shown in Examples 13 to 15 and Comparative Example 7 in Table 9 below. As the oil component, Cyclomethicone, Squalane, Argan Oil, Macadamia Oil and Dimethicone were used. The double coated powder was used as the oil component. The additives were Seed Oil, Abalone Extract Oil, Caviar Oil, Retinyl Palmitate Were used. The components are mixed together and then left for 2 hours to 5 hours to separate the oil layer and the powder layer. Oil may be separated from the upper layer, and powder may be separated from the lower layer.

[Table 9]

When such a composition is used, the application power and water repellency to the skin are increased, and the ultraviolet blocking effect is increased. The water repellency was high at 95 ~ 101% level, and the ultraviolet blocking effect was 10 ~ 30% higher than that of the continuous image. In the present invention, the continuous phase is mainly used as a water phase, but it is noted that a cosmetic composition which can be a continuous phase as an oil phase can be produced. FIG. 14 is a photograph showing the results of an experiment conducted in the example of Example 14. FIG. 14 is a photograph showing the result of separating the composite coating powder of the present invention while keeping the continuous phase in an oil phase, and leaving the mixture for 3 hours. As shown in the photograph, it can be seen that the upper layer is cleanly separated from the lower layer of the oily phase into the powder layer. These formulations can be commercialized as a product that can create a new niches market including specificity, differentiation and convenience from consumers.

Although the present invention has been described with reference to the accompanying drawings, various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the above-described embodiment, but should be determined by the claims and equivalents thereof.
