TECHNICAL FIELD The present invention relates to a water-in-oil emulsified cosmetic.

BACKGROUND ART Conventionally, cosmetics containing various film-forming agents have been studied as cosmetics for improving sebum resistance and preventing makeup deterioration due to sebum.
For example, Patent Document 1 describes that a makeup base material containing a specific fluorine-modified silicone resin having a silanol group in the molecule is resistant to makeup deterioration, is resistant to wrinkling, and has excellent cosmetic effect sustainability.

In recent years, due to the growing awareness of makeup failure, there is a demand for a cosmetic that is resistant to makeup failure due to sebum and is resistant to rubbing by physical action such as hands and clothes. With the cosmetics described in Patent Documents 1, 2, and 3, the applied cosmetics may come off due to rubbing.
In addition, the inventors have found a problem that when a make-up cosmetic such as a foundation is further applied after applying a cosmetic, the make-up cosmetic applied in layers does not adhere well, resulting in a poor finish.

The present inventors have found that by using a combination of a specific spherical organic powder, a film-forming agent, and a volatile oil, it is difficult to remove the applied cosmetic even if it is rubbed with hands or clothes, and the cosmetic can be easily removed. The present inventors have found that a water-in-oil type emulsified cosmetic can be obtained that can be uniformly applied even when the make-up cosmetic is repeatedly applied after application.

The present invention provides the following components (A), (B), (C) and (H):
(A) 0.1 to 10% by mass of spherical organic powder having a squalane oil absorption of 1.0 g/g or more and a water absorption of 1.0 g/g or less;
(B) film-forming agent 0.1 to 10% by mass,
(C) 5 to 60% by mass of volatile oil,
(H) water 5 to 70 mass%

Production Example 1 ((A) Production of spherical organic powder)
500 g of water and 1.5 g of polyvinyl alcohol were added to a beaker and stirred and mixed at 20° C. to obtain an aqueous polyvinyl alcohol solution. Then, a solution obtained by mixing and stirring 25 g of stearyl methacrylate, 40 g of styrene, 35 g of divinylbenzene, 150 g of n-heptane, and 3 g of lauroyl peroxide was added to the polyvinyl alcohol aqueous solution and stirred with a homomixer to obtain an emulsion. . The prepared emulsified liquid was added to a 2 L separable flask equipped with a stirrer, a reflux tube and a nitrogen inlet tube, heated to 70° C. with stirring, and polymerized under a nitrogen atmosphere for 10 hours. After completion of the polymerization, n-heptane was removed by an evaporator, filtered, washed with water and dried. The resulting solid matter was pulverized by a mill to obtain a porous vinyl polymer ((styrene/stearyl methacrylate) crosspolymer) having a volume average particle size of 8 μm.

Hereinafter, in the present invention, the oil absorption, water absorption and specific surface area of powdery squalane are measured according to the following methods. Table 1 shows the measurement results of the powders used in the examples.

(1) Method for measuring oil absorption of squalane in powder:
Measured with reference to the pigment oil absorption measurement method specified in JIS K5101-13-2:2004. First, 1 g of powder was placed on a glass plate, and squalane was dropped little by little using a pipette, and the powder and squalane were kneaded using a palette knife each time. When the powder and squalane turned into a hard paste, the squalane was kneaded drop by drop, and the last drop of squalane softened the paste abruptly, and the point where the paste started to flow was taken as the end point of the oil absorption. The amount of squalane (g) when reaching the end point was taken as the oil absorption per 1 g of powder. In the JIS method, boiled linseed oil is used as the oil, but in this method, squalane is used because of its similarity to sebum.
At the end point, the last drop of squalane suddenly softens the paste, and more than half of the paste is placed on the palette knife, the flat surface of the palette knife is tilted 90° with respect to the ground, and the paste is applied within 10 seconds. (If it did not fall within 10 seconds, it was not regarded as the pasty end point).
In addition, squalane was added dropwise to the powder, and the operation of pressing the squalane against the powder with a palette knife was performed twice.

(2) Method for measuring water absorption of powder:
The same method as in the method for measuring the oil absorption of squalane was carried out, except that water was used instead of squalane.

(3) Method for measuring specific surface area of powder:
For the specific surface area of the powder, about 0.1 g of the sample dried under reduced pressure at 80 ° C. for 15 hours was precisely weighed to 4 digits below the decimal point in a measurement cell, and immediately before the measurement of the specific surface area, it was placed in an atmosphere of 120 ° C. After drying for 10 minutes, it was measured by the nitrogen adsorption method (BET method) using a specific surface area measuring device (one-point BET specific surface area measuring device Flowsorb III 2305, manufactured by Shimadzu Corporation).

(2) Hardness to remove due to rubbing:
Using a 0.152 mm applicator, each cosmetic was applied to a black artificial leather (Model No. Laforet S2923 Black, manufactured by Okamoto Chemicals Co., Ltd.) in a size of 5×8 cm ² and dried for 12 hours. The cosmetic-applied part of the black leather is covered with cosmetic. Thereafter, the applied cosmetic material having a size of 2×3 cm ² was rubbed 10 times with a finger at a constant pressure, and the state of the rubbed portion was visually evaluated. The evaluation results in the table were evaluated by 5 professional evaluators on the following 5-grade scale, and the total score of the 5 persons was shown.
