SOLUTION: This solid nonaqueous powdery cosmetic is prepared by formulating polyethylene glycol (having 200-1,100 average molecular weight), polyoxyethylene methyl glucoside (having 10-20 number of mol of added ethylene oxide) or polyoxypropylene methyl glucoside (having 10-20 number of mol of added propylene oxide) in an amount of 5.0-30.0wt.% based on the total amount of the cosmetic at >=2 times (weight ratio) based on other ingredients of a nonpowdery part in the nonpowdery part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid non-aqueous powder which has an excellent moisturizing effect on the skin, prevents makeup loss due to sebum, and has a feeling of use that is not powdery and is refreshed and evenly finished. Related to cosmetics.

[0002]

2. Description of the Prior Art Conventionally, powdery solid non-aqueous powder cosmetics are less likely to form a continuous phase of a water-containing cosmetic film on the skin than other emulsified cosmetics, and therefore, provide moisture to the skin. There was a problem that it was difficult to exhibit a sustaining function. For this reason, a technique of blending a humectant such as a polyhydric alcohol has been developed in order to impart a moisturizing effect to the solid powder cosmetics (JP-A-55-28934, JP-A-55-28934).
-75405, JP-A-60-75406,
JP-A-63-215614, JP-A-02-281
06, JP-A-02-157208, and JP-A-06-219925).

[0003]

However, in any of the prior arts, since the mixing ratio of the non-powder component other than the humectant, such as polyhydric alcohol, is not specified, the moisturizing of polyhydric alcohol, etc., is not possible. Even if the agent is blended, there is a problem that the moisturizing effect of a polyhydric alcohol or the like cannot be expected if the oil-soluble components such as an oil and an activator are blended at a certain amount or more. In addition, when glycerin, which is a typical polyhydric alcohol, is added to a solid non-aqueous powder cosmetic, the solid cosmetic absorbs moisture in the air with the lapse of time because the glycerin absorbs too much moisture. Lower, is not preferred in terms of stability, and when propylene glycol, dipropylene glycol, 1,3-butylene glycol are blended with the solid nonaqueous powder cosmetic,
Due to the volatility of these polyhydric alcohols, there have been problems such as a decrease in weight over time and fogging of a mirror provided inside the cosmetic container.

[0004]

Means for Solving the Problems The present inventors have conducted intensive studies in view of the above problems, and as a result, among polyhydric alcohol humectants, polyethylene glycol, polyoxyethylene methyl glucoside, and polyoxypropylene methyl glucoside have been used as binders. When a specific amount is blended, a solid non-aqueous powder cosmetic having excellent shape retention can be obtained without the presence of a normal oil component or an activator, and the resulting cosmetic has a hardness change.
We found that there was little weight change and the mirror was not cloudy. In addition, the obtained solid non-aqueous powder cosmetic has an excellent moisture effect on the skin, prevents makeup loss due to sebum, and is contained in a base or emulsion as a powdery and refreshing powder. It has been found that it has a characteristic feeling of use that quickly adapts to moisture and evenly adheres to the skin. Further, this excellent feature is that the mixing ratio (weight ratio) of polyethylene glycol, polyoxyethylene methyl glucoside, polyoxypropylene methyl glucoside and other components of the non-powder part in the cosmetic is 2: 1 or more. They have found that they can be maintained, and have completed the present invention.

That is, the present invention relates to a solid nonaqueous powder cosmetic comprising a powder part and a non-powder part, wherein the non-powder part contains polyethylene glycol (average molecular weight: 200 to 1).
100), one or more selected from polyoxyethylene methyl glucoside (number of moles of ethylene oxide added: 10 to 20) and polyoxypropylene methyl glucoside (number of moles of propylene oxide added: 10 to 20), based on the total amount of the cosmetic. 5.0-30.0% by weight
A solid non-aqueous powder cosmetic, characterized in that it is blended twice or more (weight ratio) with respect to the other components in the non-powder part.

The amount of polyethylene glycol, polyoxyethylene methyl glucoside or polyoxypropylene methyl glucoside used in the non-powder part of the present invention is 5.0 to 30.0% by weight, preferably 10. 0 to 15.0% by weight. If the amount is more than 30.0% by weight, the powder is agglomerated and the cosmetic cannot be removed from the surface of the powder cosmetic with a sponge.
If the amount is less than the weight percentage, a solid non-aqueous powder cosmetic cannot be molded, which is not preferable.

The amount of the polyethylene glycols to be added to the other components in the non-powder portion is at least twice (weight ratio), preferably at least four times. If the ratio is less than twice, a moisture effect on the skin, a long lasting effect on sebum and a distinctive feeling of use cannot be obtained.

In the present invention, polyethylene glycol (average molecular weight: 200 to 1100), polyoxyethylene methyl glucoside (ethylene oxide addition mole number: 10 to 20) and polyoxypropylene methyl glucoside (propylene oxide addition mole number: 10 to 10) are used. ~ 2
It is more preferable to use any one of the above (0) together. Polyethylene glycol and methyl glucosides, preferably polyethylene glycol: methyl glucosides =
By using together at a ratio of 1: 1 to 3: 1, more preferably at a ratio of polyethylene glycol: methyl glucosides = 8: 3 to 8: 5, a powder cosmetic with less secondary adhesion can be obtained.

(Preparation method) The components of the powder portion are mixed and pulverized by a pulverizer. A non-powder component obtained by stirring and mixing at room temperature was added thereto, and the mixture was further uniformly mixed and pulverized by a pulverizer, taken out of the pulverizer, and compression-molded in a container such as a metal plate to obtain a powdery foundation.

As Comparative Examples 1-3, a sample containing glycerin (Comparative Example 1), a sample containing 1,3-butylene glycol (Comparative Example 2), polyethylene glycol: squalane =
A 1: 1 blended sample (Comparative Example 3) was prepared by the same method as in the example, and a water retention test, a tray test, and a usability test were performed by the following methods. Further, a change in hardness, a change in weight and a fogging of a mirror were compared. Table 2 shows the results.

(Moisture Retention Test) 1.0 g of a sample solid foundation was placed in a 20 ml screw tube, 0.1 g of ion-exchanged water was added, and the weight after leaving for 1 hour in a room at 23 ° C. and 50% relative humidity. The change is measured (n = 3), and the moisture retention of each sample solid foundation is evaluated by the moisture evaporation rate (%) represented by the following equation. The lower the water evaporation rate, the higher the water retention power. Water evaporation rate (%) = weight loss (g) /0.1

After passing 70 mg of oleic acid 20% and squalene 20% at the same time, put a 100 g weight on the back side for 60 seconds,
The degree of attachment of the foundation to the filter paper is visually determined based on the following evaluation criteria. This test simultaneously and simply evaluates the poor durability of the makeup due to sweat and sebum (Tre) and the poor secondary adhesion due to contact with clothes and the like.

Evaluation Criteria 5: 100 to 90% of the amount of the foundation applied was attached to the filter paper. 4: 89 to 60% of the applied amount of the foundation adhered to the filter paper. 3: 59 to 30% of the applied amount of the foundation adhered to the filter paper. 2: 29 to 5% of the applied amount of the foundation adhered to the filter paper. 1: Less than 5 of the applied amount of the foundation adhered to the filter paper.

(Usability Test) Ten professional panels applied the solid sample foundation to the inside of the upper arm, and evaluated the moistness, stickiness, and finished feeling according to the following criteria.

Evaluation Criteria ７: Seven or more people answered that the product was moist or smooth, or the finish was uniform. Δ: 3 to 6 people answered that the product was moist or smooth, or the finish was uniform. ×: Less than 3 people answered that the product was moist or smooth, or that the finish was uniform.

(Change in Weight) The change in weight was evaluated based on the following criteria. : Almost none. × ₁ : lower. × ₂ : Increase.

(Mirror Fogging) Mirror fogging was evaluated according to the following criteria. ：: None. X: Cloudy.
