Description

  The present invention relates to a powder cosmetic, and particularly to a powder cosmetic having excellent usability and stability and a method for producing the same.

Conventionally, powder cosmetics are mainly composed of cosmetic powders and cosmetic oils. For these types of preparations, hydrocarbon oils, ester oils, silicones are usually used as adhesive components. Hydrophobic oils such as oils have been used. These adhesive components are components that contribute to providing usability such as a feeling of adhesion to the skin, moistness, smoothness, and moisturizing skin in the system, but with a very slight moisturizing effect. It was only recognized.
Then, in order to eliminate this fault, the formulation of the water-soluble adhesive component has been tried for some time (see Patent Documents 1 to 5).

JP-A-6-219925 JP-A-8-268838 JP-A-8-291020 Japanese Patent Laid-Open No. 10-175823 JP 2001-181137 A

However, the water-soluble adhesive component has high hygroscopicity, and when blended in a powder cosmetic with a method such as Patent Document 1, the moisture absorption preventing effect on the base is not sufficient, and there is a concern that the antiseptic property is impaired. In addition, when powder cosmetics are compression molded into an intermediate dish or the like by methods such as Patent Documents 2 to 4, the hardness changes greatly under humidified conditions, or a hard film is generated on the surface of the molded product by an applicator such as a sponge. As a result, the base tends to be difficult to remove (hereinafter abbreviated as caking). On the other hand, due to the softening phenomenon due to moisture absorption, the strength against impacts such as dropping and vibration may be inferior. Moreover, although solid cosmetics can also be obtained stably by the method like patent document 5, in this case, there are few compounding of powder and the fault of lacking the refreshing feeling peculiar to powder cosmetics cannot be eliminated.
The present invention has been made in view of the above-described conventional circumstances, and an object of the present invention is to provide a powder cosmetic capable of stably incorporating a water-soluble adhesive component and a method for producing the same.

(About component (1))
The hydrophobic powder or hydrophobized powder that is component (1) used in the present invention refers to a powder having a low affinity for water, and the hydrophobic powder itself is a powder having a low affinity for water. The hydrophobized powder is a powder imparted with hydrophobicity by surface treatment of a powder having a high affinity for water. Here, the “hydrophobic” property is determined by evaluating by the following method. That is, 50 g of ion-exchanged water and 0.1 g of the evaluation powder are placed in a transparent sealed container, and then stored at 50 ° C. for 1 day, and the state is observed. As a result, when most of the evaluation powder was present on the surface of ion-exchanged water, it was determined that there was “hydrophobicity”.

  For the hydrophobization treatment of the hydrophobization treatment powder, powders usually used in cosmetics are used, for example, higher fatty acids, metal soaps, oils and fats, waxes, silicone compounds, fluorine compounds, hydrocarbons, surfactants, dextrin fatty acid esters, etc. The surface of the powder is treated with this material, and the surface treatment method is not particularly limited, and may be performed according to a normal method.

  Further, the hydrophobized powder will be described in detail. In the hydrophobizing method, the surface of the inorganic powder is preferably treated with one or more types of silicone compounds, more preferably the surface of the inorganic powder is coated with a silicone compound. One or two or more types are subjected to surface treatment, and most preferably, the surface of the inorganic powder is used as the first layer, and the surface of the powder is treated with a silicone compound having a Si—H group in the molecule.

By using the above components in combination with the essential components as the water-soluble adhesive component, an increase in the amount of keratin water and a decrease in the amount of transdermal moisture transpiration when applied to the skin can be expressed more effectively.

  The compounding quantity of a component (4) is 0.3-29 mass% in all powder cosmetics, More preferably, it is 3.0-20 mass%. If the amount is less than 0.3% by mass, the effect of the present invention cannot be sufficiently obtained. If the amount exceeds 29% by mass, a change in hardness under humidified conditions may increase.

  About the mixture of said component (2)-(4), the effect of this invention is not impaired by the mixing method. Moreover, as a total compounding quantity of component (2)-(4), it is 7-30 mass% in powder cosmetics, Preferably it is 10-25 mass%.

Examples 1-3, Comparative Examples 1-6 (powder foundation formulation)
Powder foundations having the formulations shown in Tables 1 and 2 were prepared by the following method. The hydrophobicity of the powders in Tables 1 and 2 was evaluated according to the experimental method described above.
The production method and evaluation criteria for the hydrophobicity of the powder are described below.

(Manufacturing method)
1 to 26 shown in Tables 1 and 2 were stirred and mixed, and then 27 to 36 which were uniformly heated and mixed were added and mixed. After the obtained mixture was pulverized, it was prepared by filling into a medium dish and compression molding.

(Evaluation criteria for hydrophobicity)
○: Most of the powder does not fit with water and floats on the surface (has hydrophobicity)
X: Part or most of the powder is submerged in water (no hydrophobicity)

* 1: First layer: Cyclic methyl hydrogen polysiloxane Second layer: Tetradecyl group * 2: First layer: Cyclic methyl hydrogen polysiloxane Second layer: Tetradecyl group * 3: First layer: Cyclic methyl hydrogen poly Siloxane second layer: tetradecyl group * 4: silica / zinc oxide (weight ratio) = 2/8
Average particle size: 0.03 μm

(1) Sensory test (moisture sensation on skin, moistness, no stickiness, no makeup collapse 3 hours after application)
A sensory evaluation test was performed on the foundations of the formulations shown in Tables 1 and 2 according to the following evaluation methods and evaluation criteria. That is, sensory evaluation was performed by 20 professional panels according to the following criteria for each of the moist feeling on the skin, moistness, no stickiness, and no makeup collapse 3 hours after application.

(Evaluation criteria)
Very excellent (◎): 17 or more panel that felt the effect is quite excellent (○): 12 to 16 panel that felt the effect Excellent (△): 9 panel that felt the effect ~ 11 people Somewhat effective (×): 5 to 8 panels that feel the effect No effect (××): 4 or less panels that feel the effect of the present invention

(2) Moisturizing effect test (increase in keratin moisture, decrease in transdermal moisture transpiration)
The foundation shown in Tables 1 and 2 was subjected to a continuous test that was applied twice a day for 20 months using 20 specialist panels. The increase in the amount of horny moisture in the bare skin and the amount of transdermal moisture transpiration before and after the test were conducted. The change was measured for the decrease. In addition, the evaluation criteria at that time are described below. Excellent (A): Significant difference was observed at a risk rate of 1% or less.
Quite excellent (O): Significant difference was observed at a risk rate of 5% or less.
No effect was observed (×): No significant change was observed.

(3) Stability evaluation test for humidified compression molded products (weight change, hardness change)
Samples that were compression molded after filling the foundation shown in Tables 1 and 2 and left for 2 months under conditions of a temperature of 40 ° C and a humidity of 95% were subjected to changes in the weight of the sample body and changes in hardness with the Olsen hardness tester. It measured according to the following formula | equation (1), (2).

Weight change (%) = 100 × (initial weight−weight after 2 months) / initial weight (1)
Change in hardness (%) = 100 × (initial hardness−hardness after 2 months) / initial hardness (2)

The evaluation criteria at that time are described below. Excellent (A): Only a change of 3% or less is observed.
Quite excellent (O): A change in the range of 5 to 10% was observed.
No effect was observed (×): A change of 10% or more was observed.

  Table 3 shows the results of these various tests.

As can be seen from Table 3, since Comparative Example 1 does not contain hydrophobic powder and / or hydrophobized powder, there is no stickiness compared to Examples 1 to 3 and 3 hours after application. It is inferior to the feeling of use such as no disintegration of makeup, and furthermore, the stabilization of the water-soluble adhesive component, which is the effect of the present invention, has not been obtained. In Comparative Example 2, the silicone oil and component (3) shown in Component (2) are not blended, so there is no stickiness compared to Examples 1 to 3; There is a tendency to be somewhat inferior to the feeling of use such as lack of heat, and further, stabilization of the compression-molded product under the humidified condition, which is an effect of the present invention, is not obtained at all. In addition, since Comparative Example 3 does not contain a water-soluble adhesive component and does not change in weight or hardness, it is inferior to the feeling of use such as moisture and moistness on the skin as compared with Examples 1-3. No moisturizing effect which is an effect of the present invention is obtained.
In Comparative Examples 4 and 5, the component (2) is not blended (Comparative Example 4) or the component (3) is blended (Comparative Example 5) with respect to the formulation of Example 1, so both are water-soluble adhesives. Ingredients are not stabilized. In Comparative Example 6, since the component (4) is not blended with respect to the formulation of Example 3, the moisture retention is good, but the weight change and the hardness change are caused.

  On the other hand, in Examples 1 to 3, a mixture of a hydrophobic powder and / or a hydrophobized powder, a silicone oil, a silicone compound having a specific structure, and a specific water-soluble adhesive component is blended in an appropriate composition. Therefore, it achieves a moisturizing effect and stabilization of the compression-molded product under humidification conditions while being excellent in use feeling such as moisturizing skin, moist, non-sticky feeling, and no makeup collapse after application. I was able to.
