Description

Water-in-oil type emulsifying cosmetic

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

In the past, cosmetics containing various film-forming agents were being studied as cosmetics that improve sebum-repelling properties and prevent makeup from breaking down due to sebum.

For example, Patent Document 1 discloses that a cosmetic base material containing a specific fluorine-modified silicone resin having a silanol group in the molecule is less likely to cause cosmetic breakdown, less likely to clump, and has excellent cosmetic effect persistence; Patent Document 2 discloses that a cosmetic containing an acrylic-silicone graft copolymer and/or trimethylsiloxysilicic acid has excellent cosmetic effect persistence; and Patent Document 3 discloses that a cosmetic containing an acrylic polymer having a dendrimer-type siloxane structure in the side chain has excellent cosmetic effect persistence and a feeling of use.

The present invention comprises the following components (A), (B), (C) and (H):

(A) 0.1 to 10 mass% of spherical organic powder having an absorption amount of 1.0 g/g or more and an absorption amount of 1.0 g/g or less,

(C) 5 to 60 mass% of volatile oil,

(H) Water 5 to 70 mass%

It relates to a water-in-oil type emulsified cosmetic containing .

Recently, due to the heightened awareness of cosmetic breakdown, in addition to cosmetic breakdown caused by sebum, there has been a demand for cosmetics that are not easily erased even when the applied cosmetics are rubbed off by physical actions such as hands or clothing. In the cosmetics described in Patent Documents 1, 2, and 3, there were cases where the applied cosmetics were erased by rubbing.

In addition, we found out that if you add additional makeup such as foundation after applying the cosmetic, the added makeup does not adhere cleanly, resulting in a messy finish.

The inventors of the present invention have found that, by using a combination of a specific spherical organic powder, a film-forming agent, and a volatile oil, a water-in-oil type emulsified cosmetic is obtained that is difficult to erase even when rubbed with a hand or clothing, and can be evenly applied when applying makeup cosmetics again after applying the cosmetic.

The water-in-oil type emulsified cosmetic of the present invention is one that is difficult to erase when rubbed with a hand or clothing after being applied to the skin. In addition, it spreads well when applied, is not sticky, and has a good feel. In addition, the emulsified particle size is small and stability is excellent. In addition, when applying a makeup cosmetic after applying the water-in-oil type emulsified cosmetic, it can be applied evenly, and a good finish can be obtained.

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

Here, the term "sphere" includes a sphere, an approximately sphere, a spheroid, and a spherical ellipsoid, and may also include a spherical powder having an uneven surface, a spherical powder having a surface, a spherical powder having voids inside, etc.

The oil absorption of the spherical organic powder was expressed as the oil absorption of squalane due to its similarity to sebum. In addition, the oil absorption of squalane represents the amount (g) of squalane absorbed per 1 g of powder, and the absorption amount represents the amount (g) of water absorbed per 1 g of powder.

From the viewpoints of improving the difficulty in erasing by rubbing, suppressing stickiness, and improving the uniformity when repeatedly applying a makeup cosmetic after applying the cosmetic, the oil absorption of squalane is 1.0 g/g or more, preferably 1.5 g/g or more, more preferably 1.8 g/g or more, even more preferably 2.2 g/g or more, preferably 4.0 g/g or less, more preferably 3.5 g/g or less, more preferably 3.0 g/g or less, and even more preferably 2.8 g/g or less.

Example

Manufacturing Example 1 ((A) Manufacturing of spherical organic powder)

In a beaker, 500 g of water and 1.5 g of polyvinyl alcohol were added, and the mixture was stirred at 20°C to obtain an aqueous polyvinyl alcohol solution. Thereafter, a stirred solution of 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 aqueous polyvinyl alcohol solution, and stirred with a homomixer to obtain an emulsion. The prepared emulsion was added to a 2 L separable flask equipped with a stirrer, a reflux tube, and a nitrogen inlet tube, and while stirring, the temperature was increased to 70°C, and polymerization was performed for 10 hours under a nitrogen atmosphere. After completion of the polymerization, n-heptane was distilled off using an evaporator, separated by filtration, washed with water, and dried. The obtained solid was pulverized by a mill to obtain a porous vinyl polymer ((styrene/stearyl methacrylate) crosspolymer) having an average volume particle size of 8 ㎛.

Hereinafter, in the present invention, the measurement of the oil absorption amount, water absorption amount, and specific surface area of the powder squalane is performed according to the following method. In addition, the measurement results of the powder used in the examples are shown in Table 1.

(1) Method for measuring the absorption amount of squalane in powder:

The measurement was made with reference to the pigment 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 each time, the powder and squalane were mixed using a palette knife. When the powder and squalane changed into a hard paste, squalane was mixed drop by drop, and the point at which the paste suddenly became soft and began to flow by the dropping of the last drop of squalane was taken as the end point of the absorption. The amount of squalane (g) when the end point was reached was taken as the absorption per 1 g of powder. The JIS method uses boiled linseed oil as the oil, but in this method, squalane was used due to its similarity to sebum.

Also, the end point was set as the paste was abruptly softened by the addition of the last drop of squalane, more than half of the paste was placed on the palette knife, the flat side of the palette knife was tilted 90° to the ground, and the paste fell off within 10 seconds (if it did not fall off within 10 seconds, it was not set as the end point on the paste).

In addition, the process of dropping squalane onto the powder and pressing the squalane onto the powder with a palette knife was performed twice. If the squalane and the powder were not clearly mixed, the oil absorption was set to 0 g/g.

(2) Method for measuring powder absorption:

In the method for measuring the absorption amount of squalane, the same method was performed by replacing squalane with water.

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

The specific surface area of the powder was measured by weighing about 0.1 g of a measurement sample in a measurement cell to four decimal places for a sample dried under reduced pressure at 80°C for 15 hours, drying the sample for 10 minutes in an atmosphere of 120°C immediately before measuring the specific surface area, and then using a surface area measuring device (a single-point BET surface area measuring device, Plosorb III 2305, manufactured by Shimadzu Corporation) by the nitrogen adsorption method (BET method).

Examples 1 to 27 and Comparative Examples 1 to 4

Water-in-oil type emulsified cosmetics having the compositions shown in Tables 2 to 4 were manufactured, and the size of the emulsified particle size, difficulty in erasing by rubbing, ease of application, lack of stickiness, and finish of applied powder foundation were evaluated. The results are also shown in Tables 2 to 4.

In addition, the results of measuring the emulsion particle size are shown in Table 5.

(quite)

At 25°C, powder phase (components (A), (F), (G) and other powder components) were added to mixed oil phase components (components (B), (C), (D), (E) and other oil phase components) and dispersed. Thereafter, water phase components (component (H) and other water phase components) were added and stirred to obtain a water-in-oil type emulsified cosmetic.

(Evaluation method)

(1) Size of emulsion particles:

Each water-in-oil type emulsified cosmetic was observed with an optical microscope at a magnification of 100 times, 10 emulsified particles were randomly selected for one field of view, the major diameters of the emulsified particles were measured, and the average major diameter was calculated (the first decimal place was rounded down). Scores were assigned according to the average major diameter as follows. The emulsified particle diameter is related to the storage stability, and a smaller (5) indicates better stability.

5; less than 21 ㎛.

4; 21 ㎛ or more and less than 26 ㎛.

3; 26 ㎛ or more and less than 31 ㎛.

1; 36 ㎛ or more.

(2) Difficulty in erasing by rubbing:

On black artificial leather (Model No. Laforet S2923 Black, manufactured by Okamoto Kasei Hikari), each cosmetic was applied in a 5 × 8㎠ area using a 0.152 mm applicator, and dried for 12 hours. The area of the black leather to which the cosmetic was applied was covered with the cosmetic. Thereafter, a finger was used to rub the applied cosmetic 10 times at a constant pressure for a area of 2 × 3㎠, and the condition of the rubbed area was visually evaluated. In addition, the evaluation results in the table were evaluated by five expert evaluators in the following five stages, and expressed as the total score of the five people.

5; The surface of the black leather is covered with cosmetics, and the color of the applied cosmetics has not changed.

4; The surface of the black leather is covered with cosmetics, and the color of the applied cosmetics is light.

3; There are some areas on the surface of the black leather that are not covered with cosmetics, and the color of the applied cosmetics is light.

2; There are some areas on the surface of the black leather that are not covered with cosmetics, and the color of the applied cosmetics is light.

1; Most of the surface of the black leather is not covered with cosmetics.

(3) Ease of application:
