Description

Skin cosmetics

[0001] The present invention relates to a skin cosmetic.

[0002] Conventionally, skin cosmetics intended to suppress stickiness caused by excess sebum have been investigated that incorporate a large amount of powder to provide a smooth feel while also providing a moisturizing sensation. For example, Patent Document 1 describes that a skin cosmetic containing water-absorbed porous powder, the surface of which is coated with a binder containing a crosslinked organopolysiloxane, provides a refreshing sensation while continuously suppressing stickiness caused by sebum, and can alleviate the discomfort of oily skin. (Patent Document 1) JP 2006-206545 A

[0003] The present invention relates to a skin cosmetic containing the following components (A), (B), (C), and (D): (A) 4 to 35 mass% of an oil-absorbing powder, (B) a crosslinked organopolysiloxane, (C) an oily component that is liquid at 25°C, and (D) a polyol, in which the total amount of powder including component (A) is 18 to 45 mass%. Detailed Description of the Invention

[0004] When conventional skin cosmetics contain a large amount of powder, it is difficult to ensure storage stability due to issues such as oil separation. There are also issues with the feel of the product when applied, such as spreadability and moisturizing sensation.

[0005] The present inventors have discovered that by using a combination of an oil-absorbing powder, a crosslinked organopolysiloxane, a liquid oily component, and a polyol, it is possible to obtain a skin cosmetic that, even when containing a large amount of powder, has excellent storage stability, spreads well upon application, has a moist feel when used, and yet suppresses stickiness on the skin after application.

[0006] The skin cosmetic of the present invention does not separate oil, has excellent storage stability, spreads easily upon application, does not become smudged on the skin after application, and provides a moist feel while suppressing stickiness after application and providing a smooth feel. Furthermore, for people who style their bangs so that they hang over their forehead, sweat and sebum on the forehead can sometimes cause the styled bangs to become messy, but by using the skin cosmetic of the present invention, such messiness of the bangs can also be suppressed.

[0007] Component (A) used in the present invention is an oil-absorbing powder. An oil-absorbing powder refers to a powder having an oil absorption capacity of 1 mL / g or more. From the viewpoint of improving storage stability, the oil-absorbing powder of component (A) preferably has an oil absorption capacity of 1 mL / g or more, more preferably 1.3 mL / g or more, even more preferably 1.5 mL / g or more, and preferably 4.5 mL / g or less, more preferably 4.3 mL / g or less, and even more preferably 4 mL / g or less. Furthermore, the oil absorption capacity of component (A) is preferably 1 to 4.5 mL / g, more preferably 1.3 to 4.3 mL / g, and even more preferably 1.5 to 4 mL / g.

[0008] In the present invention, oil absorption is measured with reference to the method for measuring oil absorption of pigments specified in JIS K5101-13-1:2004. Specifically, first, 1 g of powder was placed on a glass plate, and dimethylpolysiloxane (silicone 6cs) was added dropwise using a pipette. Each time, the powder and dimethylpolysiloxane were kneaded together using a spatula. This process was repeated, and the end point was determined when the paste of dimethylpolysiloxane and powder reached a smooth consistency. This paste was made to be one that could be spread without breaking or crumbling and that lightly adhered to the glass plate. The volume (mL) obtained by dividing the amount of dimethylpolysiloxane (g) at the end point by the specific gravity of dimethylpolysiloxane (0.925) was used as the oil absorption per 1 g of powder. While the JIS method uses refined linseed oil as the oil, the present invention used dimethylpolysiloxane, which is commonly used in cosmetics.

[0009] The oil-absorbing powder of component (A) is one that is commonly used in cosmetics and can be used without any particular limitation in terms of shape, such as spherical, plate-like, or needle-like, particle size, such as aerosol, fine particle, or pigment-grade, particle structure, such as porous or non-porous, etc. Examples of the oil-absorbing powder of component (A) include inorganic powders, and specific examples thereof include silica; metal silicates such as calcium silicate, magnesium silicate, strontium silicate, aluminum silicate, barium silicate, and magnesium aluminometasilicate; metal carbonates such as calcium carbonate and cobalt carbonate; metal tungstates such as calcium tungstate; metal oxides such as cobalt oxide and α-iron oxide; metal hydroxides such as hydrated iron oxide; and others such as silica gel and hydroxyapatite.

[0074] Example 20, Comparative Examples 5-6: The skin cosmetics listed in Table 4 were prepared according to the methods described above, and the sebum absorption rate, unsaturated fatty acid absorption rate, and storage stability of the skin cosmetics were evaluated in the same manner as described above. The sebum absorption rate and unsaturated fatty acid absorption rate were calculated based on the relationship between the amount of sebum collected from skin without the skin cosmetic (unapplied) and the amount of sebum collected from skin with the skin cosmetic (applied). The results are also shown in Table 4. (Method for Evaluating Sebum Absorption Rate and Unsaturated Fatty Acid Absorption Rate) (1) After washing their face, one expert panelist allowed 15 minutes of acclimation and then applied 6 mg of the skin cosmetic to an area of ​​1.7 cm x 1.7 cm on their forehead. (2) The panelists rested for 90 minutes in an environmentally variable chamber at 20°C and 40% RH. (3) After 90 minutes, a piece of cigarette paper (manufactured by Rizla) was placed on the skin to which the skin cosmetic had been applied and pressed down for 10 seconds to collect sebum. The same procedure was also performed on the forehead skin to which no skin cosmetic was applied, and sebum was collected. (4) The sebum components adhering to the cigarette paper were extracted with methanol and quantified by LC-MS. Column: Acclaim 120 (C18 3 μm 120 Å 2.1 × 50 mm, Thermo Fisher Scientific) Column temperature: 45°C Mobile phase: A) 60% methanol containing 10 mM ammonium acetate B) chloroform / methanol (1 / 1, v / v) containing 10 mM ammonium acetate 10% B (0-1 min) → 10-60% B (1-1.1 min) → 60% B (1.1-6 min) → 60-95% B (6-6.1 min) → 95% B (6.1-11 min) → 95-10% B (11-11.1 min) → 10% B (11.1-15 min) (5) The sebum absorption rate of the skin cosmetic was evaluated using the following formula. Amount of sebum (unapplied): Amount of sebum collected from skin to which a skin cosmetic was not applied Amount of sebum (applied): Amount of sebum collected from skin to which a skin cosmetic was applied (Sebum absorption rate) = 100 - (amount of sebum (applied)) / (amount of sebum (unapplied)) x 100 The "unsaturated fatty acid absorption rate" was evaluated by calculating the "unsaturated fatty acid absorption rate" from the above formula using only the amount of unsaturated fatty acids in the amount of sebum collected by the above procedure.

[0075]

[0076] The same evaluation as in the evaluation of storage stability as described above was carried out, and it was found that Example 20 was stable after one month of storage at 40° C. and −5° C. On the other hand, both Comparative Examples 5 and 6 were unstable.

[0077] The skin cosmetics shown in Table 5 were produced according to the method described above, and the viscosity of the skin cosmetics was measured in the same manner as above. The storage stability, spreadability, lack of creasing, moist feeling (non-powdery feeling), and smooth feeling were evaluated according to the same methods and criteria as above. The results are also shown in Table 5.

[0078]

[0079] Examples 1 to 19 and 21 to 23, Comparative Examples 1 to 4 The skin cosmetics listed in Tables 1, 2, and 5 were evaluated for the ability of set bangs to stay in place using the following method. The results are shown in Tables 6 to 9. (Method for evaluating the ability of set bangs to stay in place) Three expert panelists applied approximately 0.2 g of each skin cosmetic to the forehead, and evaluated the ability of the set bangs to stay in place three hours later using the following five-point scale. The results are shown as the total score of the three expert panelists. 5: The bangs did not fall out of place. 4: The bangs hardly fell out of place. 3: The bangs were somewhat resistant to falling out of place. 2: The bangs were somewhat prone to falling out of place. 1: The bangs were prone to falling out of place.
