Description

[Technical field]

[0001] The present invention relates to a water-in-oil emulsion cosmetic preparation. [Background technology]

[0002] In recent years, the number of occasions to wear masks to prevent infectious diseases such as COVID-19 has increased, which has led to fewer facial movements and weakened facial muscles, leading to an increase in the number of consumers, even among young people, who are troubled by sagging skin. As a result, there is a growing need for cosmetics that give a firm and fresh impression, in contrast to sagging skin. To give such an impression, it is important to create a three-dimensional glow that makes the cheekbones look higher. In addition, in the past, emphasis was placed on coverage in base makeup cosmetics, including foundations and primers. On the other hand, in recent years, with the use of masks, there are cases where it is not necessary to completely cover uneven skin tone, and makeup with reduced coverage that gives a bare skin feel has also attracted attention. For this reason, there is a demand for base makeup cosmetics that can easily adjust coverage for each part of the face, have a bare skin-like finish, and can firmly cover uneven skin tone that you want to hide.

[0003] There has been a technology for a makeup cosmetic that naturally corrects blemishes, dullness, and unevenness of the skin by combining barium sulfate, oil, pearlescent pigment, spherical powder, and specific titanium oxide, and furthermore, obtains a finish with a glossy, three-dimensional, and bare skin feel (see, for example, Patent Document 1). In addition, there is a technology for a water-in-oil cosmetic composition that improves the suffocating feeling of use while containing a high refractive index oil and a high refractive index polyol, and at the same time improves the durability of skin luster (see, for example, Patent Document 2). Furthermore, a technology for a powder-containing water-in-oil emulsion cosmetic that contains a specific polyhydric alcohol fatty acid ester type surfactant, a volatile oil, and a specific titanium dioxide pigment, which increases the covering power while providing a natural finish without being thick, has a good feel, and has excellent dispersion stability, has been disclosed (see, for example, Patent Document 3).

[0004] [Patent Document 1] Patent Publication No. 2021-134197 [Patent Document 2] Special Publication No. 2022-506541 [Patent Document 3] JP 2013-028567 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0005] However, in the conventional technology, it was difficult to realize a water-in-oil emulsion cosmetic that combines ease of application, coverage, three-dimensional gloss, pigment dispersibility, and smooth spreadability. For example, when a large amount of pearl pigment is added to produce gloss, the powder content in the cosmetic increases, and satisfactory quality in terms of smooth spreadability cannot be obtained. In addition, when titanium dioxide is added, while the coverage is high, there are cases where the spread is heavy, gloss is difficult to produce, and the cosmetic film becomes uneven due to poor dispersion (aggregation) of the powder. Furthermore, when a large amount of surfactant is added to increase the dispersibility of pigments such as titanium dioxide, the cosmetic film underneath tends to become twisted when applied in layers, making it difficult to adjust the coverage. Therefore, the object of the present invention is to develop a water-in-oil emulsion cosmetic that has excellent dispersibility of pigments such as titanium dioxide, spreads smoothly, and adheres uniformly to the skin to produce a three-dimensional gloss, is easy to apply in layers, and has excellent coverage. [Means for solving the problem]

[0006] In view of the above circumstances, the present inventors have found that by combining a powder dispersant having three or more ester bonds that is liquid at 25° C. with a nonionic surfactant that is solid at 25° C. in a water-in-oil emulsion cosmetic, the dispersibility of pigment-grade titanium dioxide in oil and the uniformity of the cosmetic film can be improved, and the cosmetic film can be imparted with a three-dimensional shine, covering power, and smooth spreadability. Furthermore, they have found that by containing an aqueous component that satisfies specific Hansen solubility parameters in the water phase, the compatibility between the oil-based component and the aqueous component is further increased after the water in the coating film evaporates, thereby further increasing the uniformity of the cosmetic film and making it easier to apply in layers, and have completed the present invention.

Here, liquid at 25°C means a property that has fluidity in a 25°C environment. The powder dispersant refers to a substance that has the function of preventing and dispersing powder aggregation. For example, when a powder with a hydrophilic surface is dispersed in an oil phase, it is known that the hydrophilic powders are easily bonded to each other and aggregate, and a powder dispersant that inhibits the surface action between the powders and prevents aggregation is used. In the present invention, the powder dispersant has three or more ester bonds in its chemical structure, and the ester bonds become adsorption points to the powder, and it is considered that the dispersibility of the powder exerts a high effect.

Among the polyethylene glycol fatty acid esters, PEG-30 dipolyhydroxystearate is preferred.

[0022] In the present invention, it is preferable that the HLB of component (C) is specified from the viewpoint of the dispersibility of component (A). Here, the HLB (hydrophile-lipophile balance) in the present invention is an index showing the balance of hydrophilicity and lipophilicity, and is calculated by the following (Equation 2) by Oda and Teramura et al. HLB = "Inorganic value (IV) / Organic value (OV)" x 10 (Equation 2) (See Yoshio Koda, "Organic Conceptual Diagram - Fundamentals and Applications", pages 11-17, Sankyo Publishing, 1984)

[0027] The component (D) in the present invention has a Hansen solubility parameter of √{(δp) 2 +(δh) 2} is less than 20. By using component (D) that satisfies this parameter, the solubility of components (B) and (C) is increased when the water-in-oil emulsion cosmetic of the present invention is applied, and this is more preferable in that it is easier to apply multiple layers.

[0028] The Hansen solubility parameter (hereinafter, also referred to as HSP) in this invention is a value used to predict the solubility of a substance, which was announced by Charles M. Hansen in 1967, and is a parameter based on the idea that "two substances with similar intermolecular interactions are likely to dissolve in each other." HSP is calculated by the following three parameters (unit: MPa 1 / 2 ) δd: Energy due to intermolecular dispersion forces δp: Energy due to dipole interactions between molecules δh: Energy due to hydrogen bonds between molecules These three parameters can be regarded as coordinates in a three-dimensional space (Hansen space), and when the HSPs of two substances are placed in Hansen space, the closer the distance between the two points, the easier it is for them to dissolve in each other. In other words, as the saying goes, "similar things dissolve well in each other," HSPs can be used as an index of affinity. A detailed explanation is given in the March 2010 issue of Kagaku Kogyo (Kagaku Kogyosha), and the HSPs of various substances can be obtained by using the computer software "HSPiP: Hansen Solubility Parameters in Practice" and the like. In this disclosure, unless otherwise specified, the HSPs obtained using this computer software "HSPiP: Hansen Solubility Parameters in Practice" ver.5.3.02 are used. Hereafter, the HSP of component X will be expressed as δd=δdx, δp=δpx, δh=δhx) or [δdx, δpx, δhx].

[0029] Among HSPs, δp and δh are indices that represent the polarity of a compound, and can be used to represent the polarity of a compound. By using these indices that represent polarity, the polarity of component (D) can be specified, and the solubility of polar components (B) and (C) in component (D) can be increased.

[0030] The solubility of components (B) and (C) in component (D) can be confirmed by the following method: Components (B), (C), and (D) are mixed in a beaker at a mass ratio of (B):(C):(D) = 1.5:1:1, heated to 70°C, and cooled to room temperature. The mixture is then observed to see if it has dissolved transparently.

[0031] The component (D) used in the present invention is not limited in terms of properties, origin, or other physical properties, as long as it is an aqueous component that satisfies the above parameters, and any of them can be used, and one type alone or two or more types in combination may be used. Here, the aqueous component means a component that is soluble in water. Examples of such components (D) are shown below, and the numbers in brackets following the component names indicate the HSP [δd, δp, δh] of each component.
