[0001] The present invention relates to a water-in-oil emulsion composition.

Background Art

[0002] Makeup bases are generally used to improve the spread and extension of foundations and the like applied thereon, to beautify the finish of makeup, and to improve makeup retention. In order to enhance the adhesion to foundations and the like, a water-in-oil emulsifier type in which an oily component is present in the continuous phase may be adopted. Powders are usually blended in makeup bases. Plate-shaped powders are used to enhance the adhesion to the skin and to easily form a uniform makeup film (see Patent Document 1, etc.). Spherical powders are used with the intention of making unevenness of the skin such as pores less noticeable (see Patent Document 2, etc.).

Summary of the Invention

Problems to be Solved by the Invention

[0004] < [[ID= >41]]In makeup bases, plate-shaped powders are preferred because the finish does not become thick, but they may have a poor effect of hiding defects such as spots, that is, so-called poor covering power. Spherical powders are useful for making unevenness such as pores less noticeable, but the effect may decrease over time after makeup. Also, it is required that the makeup base has good spread for foundations and the like applied thereon. In view of these circumstances, the present invention aims to provide a composition suitable for use as a makeup base, which allows subsequent makeup to adhere well, has excellent coverage for concealing blemishes and other imperfections, and makes pores and other unevenness less noticeable even after time has passed since applying makeup. [Means for solving the problem]

[0005] As a result of diligent research, the inventors conceived that the above problems could be solved by using plate-shaped powder and spherical polymethylsilsesquioxane in combination, and thus completed the present invention.

Therefore, the present invention provides a water-in-oil emulsion composition that is particularly suitable for use as a makeup base. [Modes for carrying out the invention]

[0008] The present invention will be described in detail below. In this specification, "~" means a range including the numbers before and after it. The water-in-oil emulsifying composition of the present invention contains (A) plate-like powder and (B) spherical polymethylsilsesquioxane.

[0009] (A) Plate-shaped powder In the present invention, (A) plate-shaped powder can be one that is commonly used in cosmetics, and any material can be plate-shaped, such as talc, mica, synthetic mica, titanium mica, boron, boron nitride, sericite, synthetic sericite, titanium sericite, kaolin, titanium dioxide, silica, aluminum oxide, barium sulfate, titania-silica composite oxide, etc.

[0010] Furthermore, (A) the plate-shaped powder may be subjected to hydrophobic treatment or hydrophilic treatment. The hydrophobic treatment is not limited to any treatment applied to ordinary cosmetic powders, and includes dry treatment, wet treatment, etc., using surface treatment agents such as fluorine compounds, silicone compounds, metal soaps, amino acid compounds, lecithin, alkylsilanes, oils, and organic titanates. Specific examples of surface treatment agents include fluorine compounds such as perfluoropolyethers, perfluoroalkyl phosphates, perfluoroalkylalkoxysilanes, and fluorine-modified silicones; silicone compounds such as dimethylpolysiloxane, methylhydrogenpolysiloxane, cyclic silicones, one- or both-terminated trialkoxy group-modified organopolysiloxanes, cross-linked silicones, silicone resins, fluorine-modified silicone resins, and acrylic-modified silicones; and metal stones such as aluminum stearate, aluminum myristate, zinc stearate, and magnesium stearate. Examples include soaps; amino acid compounds such as proline, hydroxyproline, alanine, glycine, sarcosine, glutamic acid, aspartic acid, lauroyl lysine, lysine and their derivatives, and acylated amino acids; lecithin, hydrogenated lecithin; alkylsilanes such as methyltrimethoxysilane, ethyltrimethoxysilane, hexyltrimethoxysilane, octyltrimethoxysilane, octyltriethoxysilane, and triethoxycaprylylsilane; oils such as polyisobutylene, waxes, fats and oils, and fatty acids; and organic titanates such as isopropyltriisostearoyl titanate.

Furthermore, the aspect ratio of (A) the plate-shaped powder in the present invention is preferably 10 to 100, more preferably 12 to 75, even more preferably 15 to 50, and particularly preferably 18 to 40. Here, the average particle diameter is a value calculated by repeatedly measuring the volume average of 30 arbitrary particles in an arbitrary field of view in a transmission electron microscope photograph. The arithmetic mean of the major axis and the minor axis of the particle is regarded as the particle diameter. In addition, the aspect ratio was determined by obtaining the average thickness by the arithmetic mean for all particles in the same field of view for which the thickness could be read, and rounding off the decimal part as the average particle diameter / average thickness.

[0013] The content of (A) plate-like powder in the composition of the present invention is preferably 0.1 to 15% by weight, more preferably 0.2 to 10% by weight, still more preferably 0.5 to 8% by weight, and particularly preferably 1 to 5% by weight of the whole composition. By using in such a range, when another cosmetic is overcoated on the composition after coating, the spreading is better, and after a lapse of time after makeup, the unevenness such as pores becomes less noticeable.

When used within such a range, when another cosmetic is overcoated on the applied composition, the spreading property becomes better, the covering power for hiding stains and the like by the coating film of the composition becomes higher, and after some time has passed after makeup, the irregularities such as pores become less noticeable.

[Examples]

[0049] The present invention will be described in more detail below with reference to examples, but the present invention is not limited to the following examples unless it exceeds the gist of the invention.

[0050] <Manufacturing Examples and Evaluation> Using the formulation components shown in Table 1, the oil phase component and the aqueous phase component were heated to 70°C to dissolve them, the aqueous phase was added to the oil phase component, and the mixture was emulsified while stirring with a homomixer to prepare an oil-water emulsion composition. Each of the obtained compositions was evaluated according to the following items and criteria. The results are shown in Table 1.

[0051] (How well makeup adheres after application) Each composition was applied to an area of ​​approximately 5cm x 5cm on the inside of the forearm, and then powder foundation was applied on top. Ten expert evaluators each evaluated the "adhesion" of the foundation on a 5-point scale, and the sum of the scores from the 10 evaluators was used as the evaluation result. 5: The foundation is even and applies very well. 4: The foundation is fairly even and applies fairly well. 3: Neither 2: The foundation is slightly uneven and doesn't apply very well. 1: The foundation is uneven and doesn't apply well.

[0052] (The degree to which pores are less noticeable 4 hours after application) Each composition was applied to the face in an appropriate amount, followed by the application of powder foundation. After 4 hours, 10 expert evaluators each evaluated the degree to which pores were less noticeable on a 5-point scale, and the sum of the scores from all 10 evaluators was used as the evaluation result. 5: Pores are completely invisible 4: Pores are barely noticeable 3: Pores are not very noticeable 2: Pores are slightly noticeable 1: Pores are very noticeable

[0053] (Coverage for blemishes) Each composition was applied to the face in an appropriate amount, and its coverage of blemishes was evaluated on a five-point scale. The sum of the scores from the 10 participants was used as the evaluation result. 5: The blemishes are not noticeable at all. 4: The blemishes are hardly noticeable. 3: The blemishes are not very noticeable. 2: The stains are somewhat noticeable. 1: The stains are very noticeable.

[0054] [Table 1]
