Description

The present invention relates to cosmetics.

Powder-containing cosmetics, in which powder is blended in cosmetics, are widely used as makeup cosmetics such as foundation, white powder, blush, eyeshadow, eyebrow, body powder, antiperspirant, and the like. After applying the cosmetic to the skin, the powder-containing cosmetic forms a cosmetic film by adhering the powder to the skin, thereby exhibiting the cosmetic effect of the powder. Therefore, in powder-containing cosmetics, it is very important that the cosmetics adhere to the skin (excellent adhesion). Various attempts have been made to improve the adhesion of such cosmetics to the skin. For example, Patent Literature 1 states that the adhesion to the skin is improved by surface-treating the blended powder with a silicone gel.

On the other hand, in a powder-containing cosmetic, especially in a make-up cosmetic, it is a very important quality that the formed cosmetic film maintains its state (make-up durability) over time. The deterioration of makeup durability is caused by external factors such as perspiration, sebum, water from the outside, and irritation (e.g., friction). is weakened, and the cosmetics float or run off from the skin. Various attempts have also been made to improve makeup durability. For example, Patent Document 2 discloses a technique of using a fluorine-containing olefin resin powder and a partially crosslinked organopolysiloxane polymer in a powdery solid cosmetic to improve makeup longevity. Patent document 2 states that the fluorine-containing olefin resin powder has water repellency and oil repellency, does not mix with sweat and sebum on the skin, and provides good make-up durability.

As described above, in the powder-containing cosmetic, the cosmetic has high adhesion to the skin (easily forms a cosmetic film), and the cosmetic film formed by the adhering cosmetic can be maintained for a long period of time. Since this performance is a basic performance, improvement in performance is always demanded by users.

An object of the present invention is to provide a cosmetic that has high adhesion to the skin (easily forms a cosmetic film) and that can maintain the cosmetic film formed by the adhering cosmetic for a long period of time. do.

Another object of the present invention is to provide a cosmetic that has little so-called powdery squeakiness, that is, the powder in the cosmetic spreads smoothly over the skin when the cosmetic is applied to the skin.

A further object of the present invention is to provide a cosmetic that causes less powder floating (feeling of powder) in a cosmetic film formed by applying the cosmetic to the skin.

The present invention provides a cosmetic containing the following components (A) to (C): (A) behendimonium ethyl stearyl phosphate, (B) 25% by mass or more of powder, and (C) an oil or surfactant. is.

According to the present invention, it is possible to obtain a powder-containing cosmetic that is highly adhesive to the skin and has a long lasting effect. Furthermore, according to the present invention, when the cosmetic is applied to the skin, it is less likely to feel a powdery squeak of the cosmetic on the skin. Hateful.

Embodiments of the present invention will be described below. In addition, the present invention is not limited only to the following embodiments. In the present specification, the range “X to Y” includes X and Y and means “X or more and Y or less”. In addition, unless otherwise specified, operations and measurements of physical properties are performed under the conditions of room temperature (20 to 25° C.)/relative humidity of 45 to 55% RH.

The first embodiment of the present invention comprises the following components (A) to (C): (A) behendimonium ethyl stearyl phosphate, (B) 25% by mass or more of powder, and (C) oil or surfactant It is a cosmetic that contains

According to the above-mentioned form, it is possible to obtain a powder-containing cosmetic that is highly adhesive to the skin and has a long lasting makeup. Furthermore, according to the present embodiment, when the cosmetic is applied to the skin, it is less likely that the cosmetic will squeak as powder on the skin, and the powdery feel caused by the cosmetic after forming the cosmetic film can be felt. Hateful.

Although the detailed mechanism by which the cosmetic of the present embodiment exhibits the above effects is unknown, it is considered as follows. It should be noted that the following mechanism does not limit the technical scope of the present invention.

For example, in order to enhance the makeup effect, it is necessary to blend a large amount of powder into the system. In order for the blended powder to exert its original cosmetic effect, it is important that the powder adheres to the skin and that the adhering powder maintains its adherence even after the passage of time. . The present inventors have found that the component (A) is very effective for exhibiting the adhesiveness of such powders and the effect of maintaining the same. Since component (A) has a high affinity for the skin, it is considered that the adhesion of the cosmetic to the skin is improved by combining it with the powder. In addition, component (A) is relatively excellent in water and oil repellency, and has poor compatibility with both aqueous components such as sweat and water and oily components such as sebum, so it also exhibits the effect of improving the longevity of makeup. it is conceivable that. However, when the component (A) is blended in a system having a powder content of 25% by mass or more, that is, a high powder content in the cosmetic, the effect of improving the skin adhesion of the cosmetic and maintaining the adhesion (makeup longevity). did not perform as expected. As a cause for this, the present inventors believe that in a system containing a large amount of powder, it is difficult for the powder and component (A) to exist uniformly in the system, and that the cosmetic effect of the powder is reduced by the addition of component (A). It is thought that this is because the function is not properly exhibited. Based on these considerations, by blending the component (C) oil or surfactant in the cosmetic, it becomes possible to uniformly disperse the component (A) in the powder and adhere the powder to the skin. Furthermore, it has been found that there is less powdery squeak and less powder floating (powdery feeling) in the cosmetic film formed by applying the cosmetic to the skin. He found this and completed the present invention.

Each component contained in the cosmetic of the first embodiment will be described below.

(Component (A): behendimonium ethyl stearyl phosphate)
Behendimonium ethyl stearyl phosphate is a compound having the following structure.

Behendimonium ethyl stearyl phosphate is a phospholipid-like compound in which a nitrogen-containing alcohol is added to a phosphate ester. Since it has such a structure, it has a very high affinity for the skin, but because it has a relatively small molecular weight, it interacts with the powder and easily binds to the powder surface, and the powder spreads evenly on the skin. It is thought to play a role in helping to adhere to Therefore, by blending the component (A) in the powder-containing cosmetic, the powder easily adheres to the skin (easy to form a cosmetic film), and the lack of powdery creaking and powdery feeling (cosmetic film uniformity) can easily be obtained. In addition, behendimonium ethyl stearyl phosphate has a good balance of lipophilicity and hydrophilicity, and is excellent in water repellency and oil repellency.
