The present invention relates to a water-in-oil emulsified makeup cosmetic composition having excellent adhesion without changing the composition and properties of the pigment component and the aqueous phase component in the oil component, pigment component, aqueous phase component and fragrance which are cosmetic components without affecting the spreadability. will be.

In general, make-up cosmetics are applied to the outermost surface of the face at the time of makeup is required a certain level of adhesion.

In order to increase the adhesion, an organic polymer, an inorganic thickener, or an organic / inorganic hybrid thickener which generally increases the content of waxes such as ozokerite, carnauba wax, beeswax, etc., which are high in the oily ingredients, The content was increased to increase the feeling of adhesion during makeup. However, when the wax content in the oil phase component is increased, the density of the wax formulation in which the crystals in the oil phase component are formed increases with respect to the total volume, resulting in poor fluidity, which causes the spread of the makeup cosmetics to the skin. In the case of makeup, there is a disadvantage in that the ease of use, the feeling becomes heavy, and the flowability worsens. In the case of a thickener, there is a problem in that the similarity to the action to reduce the spread.

As a result of repeated studies to solve the above-mentioned conventional problems, the present inventors have found that the pigment sort, morphology, size and content (%) of pigments have a great influence on various factors. It was found that the water-in-oil emulsion makeup cosmetics had a great influence on the adhesion, and the composition, type and characteristics of the moisturizing agent in the pigment component of the pigment component and the moisturizing agent in the water-based component of the oil-in-water emulsion makeup cosmetic were adjusted. As a result, it has been found that it is possible to improve the mutual contradiction relationship in which the adhesion of the make-up cosmetics is improved when the adhesion is improved and the adhesion is worsened when the adhesion is improved.

Accordingly, the present inventors introduced a plate-like pigment having an excellent effect on adhesion while having a slight influence on the fluidity even when the content was increased, and the water phase component, which is the inner phase of the formulation, is an oil phase, which is an outer phase. The spherical dispersion inside does not affect the fluidity under the same conditions, and the fluidity, that is, spreadability when applied to the skin, is not affected when the oil-in-water emulsion makeup cosmetic composition is applied to the skin. In view of the fact that it is not given, the above-mentioned technical difficulties can be solved by introducing a solid or semi-solid polyol into the water phase which can improve the adhesion after volatile components such as water are absorbed into the skin or volatilized in the air.

Therefore, the object of the present invention is to understand the behavior of the components of the water-in-oil emulsified make-up cosmetics when applying the water-in-oil emulsified make-up cosmetics to the skin by applying a certain pressure and shear, the mutual contradiction of adhesion and spreadability It is to provide a composition of a new water-in-oil emulsified makeup cosmetics that presented an alternative that overcomes the relationship.

In order to achieve the above object, the present invention is characterized by using a plate pigment as a pigment component, and using a polyol component in the solid phase or paste form (hereinafter, 'paste phase' is referred to as 'semi-solid') as the aqueous phase component. It provides a water-in-oil emulsified makeup cosmetic composition.

The plate pigment is at least one selected from the group consisting of talc, mica, sericite, barium sulphate (BaSO ₄ ), alumina (Al ₂ O ₃ ), boron nitride and bismuth oxychloride (BiOCl) It is characterized by that.

In addition, the solid or semi-solid polyol component is selected from the group consisting of xylitol, erythritol, sucrose, lactose, lactose, maltose, sorbitol, and mannan. It is characterized by one or more.

Hereinafter, the present invention will be described in more detail.

The cosmetic composition consists of an oil phase component, a pigment component, an aqueous phase component, and a fragrance. Oily ingredients are commonly used in conventional makeup cosmetics and consist of ester-based oils, waxes, preservatives, silicone oils, thickeners, polymers, etc.Pigmental ingredients consist of plate-like pigments, iron oxides, etc. It consists of purified water, moisturizer, ion blocker, cationic component, and preservative.

The pigment component occupies about 5 to 20% by weight in the water-in-oil emulsified makeup cosmetics and is a factor that greatly affects the feeling of use, such as adhesion, spreadability, weight, and coverage of the makeup cosmetics. Titanium dioxide and zinc oxide, which are generally used as pigments, improve cover or UV protection, while PMMA (polymethyl methacrylate) helps to disperse other pigments, grabs oil, and improves the feeling of use. It has a function, and iron oxide has a function of imparting color to makeup cosmetics.

Various experiments showed that the sort, morphology, size and content (%) of pigments affect the adhesion of water-in-oil emulsified makeup cosmetics. If the conditions are the same in the dual morphology, it is already known that the difference of adhesion depends on the contact area with the skin. That is, it is known that plate-like pigments can enhance the adhesion more than spherical pigments. As a result of experiments on the differences of plate pigments by size and size, the same plate pigments did not show any significant difference in the adhesiveness regardless of the type of pigment, but the difference was marked by size. That is, even if the same type of plate pigments of the same type, the plate pigments having a small size (mean size average size per sphere, below mean average particle size, size, size, etc.) means a close feeling. It was found to be high (see FIG. 1).

Accordingly, the plate pigment of the present invention is selected from the group consisting of talc, mica, sericite, barium sulphate (BaSO 4), alumina (Al ₂ 0 ₃ ), boron nitride (BORON NITRIDE) and bismuth oxychloride (BiOCl). It is characterized by more than one species.

Generally, pigments used in makeup cosmetics are used without surface treatment or by coating the surface with various substrates such as dimethicone, alkyl methoxycaprylyl silane, stearic acid, etc. The adhesion was confirmed to increase. However, it was confirmed that the effect of oil-in-water emulsified makeup cosmetics on the stability of the emulsion depends on the surface properties.For example, mica, unlike other flaky pigments, has a strong hydrophilic surface and destroys the emulsion film. It can be seen that it adversely affects the stability of the. In this case, it could be found that the coating treatment to make the surface hydrophobic prevents the breakdown of the emulsion film and helps stabilize the formulation. The surface treatment of plate pigments is methicone, dimethicone, isopropyl titanum triisostearate, alkyl fluoroalcohol phosphate, lauric acid lysine (N-lauroyl -L-lysine, chitosan, stearic acid, acrylate silicone copolymer, lecithin, carnauba wax, ozokerite, beads Wax (bees wax), multi wax (multi wax) and triethoxy caprylysilane (triethoxycaprylysilane) is characterized in that one or more selected from the group consisting of. In order to maximize the feeling of adhesion in the size of the plate pigments, it was found that it is advantageous to use a plate pigment in the range of 0.1 ~ 5㎛ average particle size. There may be some differences depending on the prescription, but the size of the rapid change in adhesion is about 5㎛ compared to the change in the size of the plate pigment. It is understood that the plate pigment has a large surface area per unit weight, and the adhesion is rapidly increased at the boundary of 5 μm. Moreover, when it is less than 0.1 micrometer, a pigment shape does not become a plate shape, but becomes a granular shape, and a rough usability is shown.

In addition, the plate pigment is characterized in that it contains 0.5 to 5.0% by weight based on the total cosmetic composition. If the content is 0.5% by weight, most people will be able to discern the difference between the plate pigment and the one not. In addition, when the content is more than 5.0% by weight, the viscosity rise is too high, it is difficult to fill in the container, adversely affect the stability of the emulsion even in the formulation, the thickness of the makeup film is sharply increased, which causes the makeup becomes stuffy. .

The moisturizer, one of the water-based ingredients, forms a film on the skin or catches moisture in the air to maintain a certain level of moisture in the stratum corneum to prevent dryness and to provide moist usability. However, through several experiments, it was found that depending on the type of water-soluble moisturizer that is dissolved in water can improve the adhesion in addition to the above purpose.

As a result of research on moisturizer or film forming agent that can be used as an aqueous phase due to its ability to dissolve in water, polyvinyl pyrrolidone and vinylpyrrolidone / vinylacetate copolymer (VP / VA Copolymer) Vinyl acetate and vinylpyrrolidone monomers, polyvinyl alcohol, polyester-5 (DIGLYCOL), cyclohexane dimethanol, isophthalate (ISOPHTHALATES) , SIPCOPOLYMER), Polyurethane-1 / Ethanol, Acrylate copolymer, Xantan Gum or Sodium Carboxymethyl Cellulose (CMC-NA) (copolymer), and the materials are not uniformly dissolved due to entanglement with a cationic component such as NACL in the aqueous phase or a preservative component such as phenoxy ethanol (see FIG. 2). ), Even when dissolved in the water phase to form the emulsion particles, the size of the emulsion particles may be increased or the particle size becomes uneven to accelerate the separation phenomenon of the water-in-oil emulsion makeup cosmetics (see Fig. 3). ).

In addition, some of the water-soluble polymer was found to be the phenomenon that the film film is pushed when the water-in-oil emulsion makeup cosmetics applied to the skin.

The present inventors studied a water-soluble material that can improve the adhesion without the various problems mentioned above, and as a result, solid or semi-solid polyol does not entangle with other substances in the aqueous phase while increasing the adhesion and affects the stability of the emulsion. I found it not crazy. The polyol component generally used is known to have moisturizing effect on the skin, but (Application Serial No. (Application Number): 2004-0105555 (2004.12.14 ) xylitol, and beta-1, 3-cosmetic composition for a skin moisturizer containing the -glucan- When a solid or semi-solid polyol is used in the water-in-oil emulsified makeup cosmetic composition at room temperature, it has been found that the adhesion is improved without reducing the spreadability of the makeup cosmetic composition (see FIG. 4).

In the water-in-oil emulsified makeup cosmetic composition, the solid or semi-solid polyol component included in the aqueous phase is present as a liquid in the aqueous phase, and when the makeup cosmetic composition is applied to the skin, the emulsion film is broken and the liquid polyol and Water-soluble components are applied to the skin, and volatile components such as water are absorbed into the stratum corneum of the skin relatively quickly or volatilized to the atmosphere. The liquid polyol component changes to a thin solid phase in the process of returning to its original solid form or semi-solid form. It gives a close feeling. The amount of the solid or semi-solid polyol showing the feeling of adhesion tends to increase as the content thereof increases.

In addition, the solid or semi-solid polyol used in the formulation is preferably contained in 0.1% to 10% by weight in the makeup cosmetic composition. 0.1% by weight is the minimum content of the solid or semi-solid polyols to cause a feeling of adhesion, and in excess of 10% by weight, the amount of polyols in the inner phase increases in the emulsifier type, which adversely affects the stability of the emulsion, so that the emulsified particles easily coalesce, If it is more than 10% by weight, the user may feel a soft feeling of using the candle after application.

The makeup cosmetic composition according to the present invention is not particularly limited in its formulation, but may be formulated in a cosmetic form such as makeup base, foundation, concealer, and the like.

Hereinafter, the present invention will be described in more detail with reference to Examples and Test Examples, but the present invention is not limited only to these examples.

As described above, the water-in-oil emulsified makeup cosmetic composition provided by using a small plate-like pigment and a solid or semi-solid polyol in the water phase component has an effect of improving adhesion. In particular, the adhesion of cosmetics was increased by changing the content of wax or thickener of the external cosmetics in the existing cosmetics, but overcoming the disadvantage that the spreading was deteriorated, and the adhesion can be improved without deteriorating the spreading property, which is an important property of makeup cosmetics. And at the same time it can provide a new makeup cosmetic composition that does not affect the weight of the makeup.
