Description

The present invention relates to powdered cosmetics and a method for producing the same.

Powdered cosmetics containing powder in cosmetics are widely used as makeup cosmetics such as foundations, white powder, teak, eye shadow, and eyebrow, body powders, antiperspirants, and the like. In powder cosmetics, after the cosmetic is applied to the skin, the powder adheres to the skin to form a cosmetic film, and the cosmetic effect of the powder is exhibited. Therefore, in powdered cosmetics, it is very important that the cosmetic adheres to the skin (excellent adhesiveness). Various attempts have been made for the purpose of improving the adhesion of such cosmetics to the skin. For example, Patent Document 1 states that the powder to be blended is surface-treated with a silicone gel to improve the adhesion to the skin.

Further, in powder cosmetics, particularly in make-up cosmetics, it is very important that the formed cosmetic film is maintained in that state even after a long time (makeup retention). Deterioration of makeup retention is caused by external factors such as sweat, sebum, or external water or irritation (for example, rubbing), which causes the adhered cosmetics to lose their affinity for the skin or to the adhered cosmetics to the skin. This is caused by the weakening of the affinity of the skin and the fact that the cosmetics float or run off the skin. Various attempts have been made to improve the longevity of makeup. For example, Patent Document 2 discloses a technique of using a fluorine-containing olefin resin powder and a partially crosslinked organopolysiloxane polymer in a powder solid cosmetic in order to improve the cosmetic retention. 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 makeup retention.

On the other hand, in powdered cosmetics, talc and titanium oxide can be blended to enhance the effect of powdered cosmetics on the skin, so that talc and titanium oxide are general-purpose components in powdered cosmetics.

International Publication No. 2014/102862 Japanese Unexamined Patent Publication No. 2003-238340

However, since talc and titanium oxide have strong bonding force between powders, highly water-repellent components such as the silicone gel described in Patent Document 1 and the fluorine-containing olefin resin powder described in Patent Document 2 are powdered. When contained in the agent, talc and titanium oxide may aggregate, and powder aggregates may be present in the powder cosmetics.

Therefore, according to the present invention, the adhesiveness to the skin is high (the cosmetic film is easily formed), the cosmetic film formed by the adhered cosmetic film can be maintained for a long period of time, and the powder cosmetic film can be maintained. An object of the present invention is to provide a cosmetic that can reduce the agglomeration of powder.

Another object of the present invention is to provide a powdered cosmetic which can improve the slipperiness of the powdered cosmetic on the skin while maintaining the adhesiveness to the skin.

The present invention contains the following components (A) to (C); (A) stearyl behendimonium ethyl phosphate, (B) N-acylamino acid or a salt thereof, and (C) at least one of talc or titanium oxide. , Powdered cosmetics.

According to the present invention, it is possible to obtain a powdered cosmetic having high adhesion to the skin and having a long-lasting makeup. Furthermore, according to the present invention, agglomeration of powder in powder cosmetics can be reduced. Further, according to the present invention, it is possible to improve the slipperiness of the powdered cosmetic on the skin while maintaining the adhesiveness of the cosmetic to the skin.

Hereinafter, embodiments of the present invention will be described. The present invention is not limited to the following embodiments. In the present specification, "X to Y" indicating a range includes X and Y and means "X or more and Y or less". Unless otherwise specified, operations and physical properties are measured 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)-(C); (A) stearyl behendimonium ethylphosphate, (B) N-acylamino acid or a salt thereof, (C) talc or titanium oxide. A powdered cosmetic containing at least one of them.

According to the above form, a powdered cosmetic having high adhesion to the skin and having a long-lasting makeup can be produced. Furthermore, according to the present invention, agglomeration of powder in powder cosmetics can be reduced. Further, according to the present invention, it is possible to improve the slipperiness of the powdered cosmetic on the skin while maintaining the adhesiveness of the cosmetic to the skin.

The detailed mechanism by which the cosmetics of the present embodiment exert the above effects is unknown, but it is considered as follows. 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 add a large amount of powder to 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 adhered powder maintains its adhesiveness even after a lapse of time. .. The present inventors have found that the component (A) is very effective in exhibiting the adhesiveness of the powder and its maintaining effect. Since the component (A) has a high affinity for the skin, it is considered that the component (A) improves the adhesion of the cosmetic to the skin when combined with the powder. In addition, component (A) is relatively excellent in water and oil repellency, and has poor compatibility with both water-based components such as sweat and water and oil-based components such as sebum, so that the effect of improving makeup retention is also exhibited. it is conceivable that.

However, it has been found that in powder cosmetics containing talc or titanium oxide, when the component (A) is added, agglomerates of powder are likely to be formed. Talc and titanium oxide have high bondability between powders, and the coexistence of highly water-repellent, oil-repellent, and crystalline component (A) reduces the dispersibility of the powder and makes the powder cohesive. It is thought that this is because the number is further increased.

As a result of diligent studies based on such consideration, it was found that the N-acylamino acid of the component (B) or a salt thereof reduces the cohesiveness of the powder. By blending the N-acylamino acid of the component (B) or a salt thereof in the cosmetic, the component (B) adheres to the powder surface, and the detailed mechanism is unknown, but the dispersibility of the powder is improved. However, it is considered that the aggregation of powders can be suppressed.

Further, the component (B) has a high affinity for the powder surface, and it is considered that the component (B) adheres to the powder surface to improve the slipperiness of the cosmetic when the cosmetic is applied. ..

The above estimation does not limit the technical scope of the present invention.

Hereinafter, each component contained in the cosmetic of the first embodiment will be described.

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 easily interacts with the powder and easily binds to the powder surface, so that the powder is uniform on the skin. It is thought to play a role in helping to adhere to the skin. Therefore, by blending the component (A) into the powder cosmetics, the powder easily adheres to the skin (the cosmetic film is easily formed), and there is no powder squeak or powdery feeling (uniformity of the cosmetic film). It is easy to obtain effects such as sex). In addition, stearyl behendimonium ethylphosphate has a good balance of lipophilicity and hydrophilicity, and is excellent in water repellency and oil repellency, so that it is possible to impart an effect of improving makeup retention.

(Other ingredients)
In addition to the above ingredients, surfactants, water, preservatives, antioxidants, cosmetological ingredients, antibacterial agents, chelating agents (EDTA, etc.), etc., which are usually used in powder cosmetics, are appropriately added as long as they do not interfere with the effects of the present invention. Can be contained.

The powdered cosmetics of the present embodiment include makeups such as foundation, face powder (for example, white powder), concealer, eye color (eye shadow), eye liner, eyebrow, mascara, teak, lipstick, sunscreen cosmetics, and makeup base. Cosmetics: Applicable to body powders, antiperspirants, lip creams, skin care cosmetics such as beauty liquids and milky lotions, and preferably foundations, face powders, and eyes, which are expected to further exert the effects of the present application. Makeup cosmetics such as color, makeup base, sunscreen cosmetics, and teak. In addition, the method of use includes a method of using with a hand or a finger, a method of impregnating with a puff, a sponge, or the like.

The dosage form of the powdered cosmetic of the present invention is not particularly limited, and may be solid or loose. Since the effects of the present embodiment are further exhibited and the impact resistance is improved by the aspect of the present invention, it is preferable that the cosmetic is a solid solid powder cosmetic. .. Here, the powdered cosmetic refers to a cosmetic containing 50% by mass or more of powder, and more preferably 70% by mass or more, and 80% by mass or more, because the effect of the present invention is further exhibited. It is more preferable, and it is further preferable to contain 85% by mass or more.

The powdered cosmetic of the present embodiment can be produced by a conventionally known method. For example, in the case of solid powder cosmetics, a dry press method in which powdered cosmetics are filled in a container such as a gold plate and then pressurized, or a solvent such as a volatile compound is added to a composition in which the above components are mixed. It can be produced by a wet filling method in which a slurry is formed, filled in a container such as a gold plate, pressed to remove a part of the solvent, and the solvent is completely removed.

The filling method may be either a dry pressing method or a wet filling method, but even when a volatile solvent is used, the inhibition of aggregation of talc and titanium oxide can be effectively suppressed, so that the component (A) A wet filling method in which the cosmetic base material containing (C) to (C) and a volatile solvent are mixed to form a slurry, filled in a container, and then the volatile solvent is removed is described in the components (A) to (C). It is more preferable because it is more excellent in improving the drop strength due to the uniform dispersion of C).

That is, another embodiment of the present invention comprises (i) component (A) stearyl behendimonium ethyl phosphate, component (B) N-acylamino acid or a salt thereof, and component (C) talc or at least one of titanium oxide. And the process of preparing the cosmetic base material,
(Ii) A step of mixing the cosmetic base material and a volatile solvent to form a slurry, and
(Iii) A step of removing the volatile solvent after filling the container with the slurry.
It is a method for producing a powdered cosmetic containing.

Examples of the volatile solvent used in the wet filling method include water; low boiling point alcohols such as ethyl alcohol, propyl alcohol, isopropyl alcohol and butyl alcohol as aqueous solvents, and hydrogenated polyisobutene and isododecane as organic solvents. Can be mentioned. An aqueous solvent is more preferable as the volatile solvent because it can effectively suppress the aggregation of talc and titanium oxide. As the aqueous solvent, water alone or an alcohol aqueous solution in which a low boiling point alcohol is dissolved in water is preferable. The low boiling point alcohol concentration in the alcohol aqueous solution is preferably 50% by mass or less. The higher the alcohol concentration in the alcohol aqueous solution, the better the dispersion of the cosmetic base material during the slurry preparation, the better the feeling of use, and the more solid powder cosmetic having sufficient drop strength can be obtained.

The mixing amount of the volatile solvent is arbitrarily selected to the extent that fluidity is imparted in order to fill the container or the inner plate with the mixture before molding, but the volatile solvent 10 is added to 100 parts of the cosmetic base material. It is preferable to use ~ 200 parts. Within this range, the removal of the volatile solvent is good.

Further, the fluidity in the present invention is a container in which a mixture of a cosmetic base material containing a powder as a main component and a volatile solvent is mixed with an inner diameter of 2.47 cm, a body diameter of 4.05 cm, and a total height of 7.4 cm. Put 30g in (Daiichi Glass Co., Ltd. "Yakubin PS-6K"), plug it with the attached lid, tilt it 90 ° in an environment of 25 ° C and 1 atm, and let it stand for 1 minute to make a part of the mixture. Means that is attached to the inside of the lid.

In the method for preparing powdered cosmetics, the method for removing the volatile solvent is not particularly limited, and a generally known method can be used, and the powdered cosmetics can be dried as it is or filled by mixing the cosmetic base material and the volatile solvent. It is preferable to adopt a method of pressurizing afterwards to remove the volatile solvent through the absorber or the discharge hole. For example, when a mixture of a cosmetic base material and a volatile solvent is filled in a container or an inner plate, it is preferable to press it weakly with a pad or the like in order to smooth the surface. A press head or absorber can also be used to absorb the volatile solvent. It is also possible to remove the volatile solvent by drying, and the conditions for that are appropriately set according to the boiling point and specific heat of the volatile solvent. For example, in the case of light liquid isoparaffin, the temperature is 50 to 70 ° C. It takes about 10 to 20 hours.

The effects of the present invention will be described with reference to the following examples and comparative examples. In the examples, the indication of "parts" or "%" may be used, but unless otherwise specified, it indicates "parts by mass" or "% by mass". Unless otherwise specified, each operation is performed at room temperature (25 ° C.).
