Description

Water-in-oil type emulsion cosmetic

Technical Field

The present invention relates to a water-in-oil type emulsion cosmetic.

Background

Conventionally, cosmetics containing various skin membrane-forming agents have been studied as cosmetics for improving sebum resistance and preventing makeup removal due to sebum.

For example, patent document 1 describes that a base makeup cosmetic containing a specific fluorine-modified silicone resin having a silanol group in the molecule is not easy to remove makeup and to stick powder, and has excellent persistence of a makeup effect; patent document 2 describes that a cosmetic containing an acrylic acid-silicone graft copolymer and/or trimethylsiloxy silicic acid is excellent in the persistence of the cosmetic; patent document 3 describes that a cosmetic containing an acrylic polymer having a dendrimer-type siloxane structure in a side chain is excellent in makeup retention and feeling in use.

Detailed Description

In recent years, due to the increased awareness regarding makeup removal, there has been a demand for a makeup cosmetic that is not easily removed even when applied makeup is rubbed by the physical action of hands, clothes, or the like, in addition to makeup removal by sebum. With respect to the cosmetics described in patent documents 1, 2, and 3, the applied cosmetics may be peeled off by friction.

In addition, it was found that: if makeup cosmetics such as foundation are further applied in addition after the makeup cosmetics are applied, the additionally applied makeup cosmetics do not adhere perfectly, and the makeup looks dirty.

The present inventors have found that by using a specific spherical organic powder in combination with a film-forming agent and a volatile oil, a water-in-oil type emulsion cosmetic can be obtained which is less likely to come off even when the applied cosmetic is rubbed with hands, clothes, or the like, and which can be applied uniformly when the makeup cosmetic is applied and then applied.

The water-in-oil type emulsion cosmetic of the present invention is less likely to come off even when the water-in-oil type emulsion cosmetic is applied to the skin by rubbing with hands, clothes, or the like. Further, the coating composition had good spreading properties when applied, suppressed sticky feeling, and had good touch. In addition, the emulsion particle size is small and the stability is excellent. Further, even when a makeup cosmetic is applied in a superimposed manner after the water-in-oil type emulsion cosmetic is applied, uniform application is possible, and good makeup can be obtained.

The component (A) used in the present invention is a spherical organic powder having an oil absorption of squalane of 1.0g/g or more and a water absorption of 1.0g/g or less.

The spherical shape includes a spherical shape, a substantially spherical shape, and a rotational ellipsoid, and may be a spherical powder having irregularities on the surface thereof, a spherical powder having voids on the surface thereof or inside thereof, or the like.

The oil absorption of the spherical organic powder is represented by the oil absorption of squalane due to the similarity between squalane and sebum. Further, the oil absorption of squalane represents the amount (g) of squalane absorbed per 1g of powder, and the water absorption represents the amount (g) of water absorbed per 1g of powder.

Examples

Production example 1 (production of spherical organic powder (A))

The polyvinyl alcohol aqueous solution was obtained by adding 500g of water and 1.5g of polyvinyl alcohol to a beaker and stirring and mixing the mixture at 20 ℃ to obtain a polyvinyl alcohol aqueous solution, then adding a solution obtained by stirring and mixing 25g of stearyl methacrylate, 40g of styrene, 35g of divinylbenzene, 150g of n-heptane and 3g of lauroyl peroxide to the polyvinyl alcohol aqueous solution and stirring the mixture with a homomixer to obtain an emulsion, adding the prepared emulsion to a separable flask 2L equipped with a stirrer, a reflux pipe and a nitrogen introduction pipe, raising the temperature to 70 ℃ while stirring, and carrying out polymerization for 10 hours under a nitrogen atmosphere, after the completion of polymerization, distilling off the n-heptane with an evaporator, filtering and separating the mixture, washing the separated solid with water and drying the solid matter obtained, and pulverizing the solid matter obtained with a grinder to obtain a porous vinyl-based polymer ((styrene/stearyl methacrylate) crosslinked polymer) having a volume average particle size of 8 μm).

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

(1) The method for measuring the oil absorption of squalane powder comprises the following steps:

measured in accordance with JIS K5101-13-2: the oil absorption measurement of the pigment specified in 2004 was carried out as a reference. Firstly, 1g of powder is taken out and put on a glass plate, squalane is gradually added dropwise by a pipette, and the powder and squalane are kneaded by a palette knife (palette knife) each time. After the powder and squalane were changed to a hard paste, 1 drop of squalane was added each time, and the point at which the paste rapidly softened and started to flow due to the last 1 drop of squalane added was set as the end point of oil absorption. The squalane amount (g) at the time of reaching the end point was defined as the oil absorption per 1g of powder. In the JIS method, as the oil, boiled linseed oil is used, and in the present method, squalane is used due to its similarity to sebum.

The end point is set as follows: the paste was softened sharply by the last 1 drop of squalane, half or more of the paste was placed on the toning knife, the flat surface of the toning knife was inclined at 90 ° with respect to the ground, and the paste dropped within 10 seconds (when the paste did not drop within 10 seconds, it was not regarded as a pasty end point).

Further, when squalane was dropped into the powder and pressed against the powder with a toning knife 2 times and the squalane and the powder were not significantly mixed, the oil absorption was set to 0 g/g.

(2) Method for measuring water absorption capacity of powder:

in the method for measuring the oil absorption of squalane, squalane is changed to water and the same method is used.

(3) Method for measuring specific surface area of powder:

the specific surface area of the powder was measured by a nitrogen adsorption method (BET method) using a specific surface area measuring apparatus (single-point BET specific surface area measuring apparatus FlowSorb III 2305, manufactured by shimadzu corporation) after a sample dried under reduced pressure at 80 ℃ for 15 hours was precisely weighed about 0.1g to 4 decimal places in a measuring cell and dried in an atmosphere at 120 ℃ for 10 minutes immediately before the specific surface area was measured.

(preparation method)

The powder phase (components (A), (F), (G) and other powder components) is added to the oil phase components (B), (C), (D), (E) and other oil components) after mixing at 25 ℃ and dispersed. Thereafter, the water phase component (H) and other aqueous components) was added and stirred, thereby obtaining a water-in-oil type emulsion cosmetic.
