Abstract
Description
[Technical Field]
[0001] The present invention relates to a solid powder cosmetic preparation. [Background technology]
[0002] Powder cosmetics, which are cosmetics blended with powder, are widely used as makeup cosmetics such as foundation, face powder, blush, eye shadow, eyebrow pencil, etc. Among these, many solid powder cosmetics that are molded into a solid form have been put on the market in terms of portability and texture.
[0003] Methods for molding solid powder cosmetics include a dry molding method in which a powdered composition is filled into a container such as a metal dish and then pressurized, and a wet molding method in which a solvent such as a volatile compound is added to a cosmetic base containing powder and oil to form a slurry, which is then filled into a container such as a metal dish and then molded by removing the solvent. Solid powder cosmetics obtained by the wet molding method have a smooth feel when used because the powder is systematically arranged to achieve a higher density when the solvent is removed from the slurried cosmetic base. However, when the solvent used in the wet molding method is removed, cracks can occur on the surface or gaps can form between the container and the powder cosmetic due to shrinkage, resulting in poor impact resistance.
[0004] Various means have been proposed to improve such impact resistance. Patent Document 1 discloses a solid powder cosmetic obtained by wet molding a cosmetic base containing fluorine-treated talc, hydrophobically treated silica, hydrophobically treated fine particle titanium dioxide, and a water-holding oil agent. [Prior art documents] [Patent documents]
[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-177640 Summary of the Invention [Problem to be solved by the invention]
[0006] Various studies have been conducted to date on improving the impact resistance of solid powder cosmetics obtained by wet molding as described above. However, attempts to improve impact resistance usually result in the cosmetics becoming harder, which makes it difficult for the cosmetics to be removed when the user tries to take the solid powder cosmetic with their fingers or an applicator (poor cosmetic removal), making it difficult for the appropriate amount of cosmetic to be applied to the fingers or applicator.
[0007] Furthermore, after applying a solid powder cosmetic to the skin, the powder adheres to the skin, forming a cosmetic film, thereby achieving the cosmetic effect of the powder. Therefore, for solid powder cosmetics, adhesion of the cosmetic to the skin (excellent adhesion) is extremely important for achieving the cosmetic effect. Furthermore, the ability to maintain the cosmetic film formed by the adhered cosmetic for a long period of time is a fundamental performance, and therefore improvements in this performance are always desired by users.
[0008] However, solid powder cosmetics obtained by wet molding have not been sufficient in terms of achieving both improved impact resistance and a good feel when used (particularly the texture of the solid powder cosmetics, the adhesion of the solid powder cosmetics, and the durability of the cosmetic effect).
[0009] Therefore, an object of the present invention is to provide a solid powder cosmetic that has good flowability to an applicator, high adhesion to the skin, long-lasting cosmetic effects, and excellent impact resistance. [Means for solving the problem]
[0010] The present invention relates to the following components (A) to (E): (A) Fluorine-modified silicone oil (B) Silicone wax (C) Silicone oil (excluding components (A) and (B)) (D) A compound having a hydrophilic group and a lipophilic group in one molecule, and the lipophilic group is of a double-chain type. (E) Powder The solid powder cosmetic is obtained by removing the solvent from a mixture of a cosmetic base containing the above compound and a solvent. [Effects of the Invention]
[0011] The solid powder cosmetic of the present invention exhibits good adhesion to applicators, high adhesion of the cosmetic to the skin, long-lasting cosmetic effects, and excellent impact resistance. DETAILED DESCRIPTION OF THE INVENTION
[0012] Hereinafter, embodiments of the present invention will be described. However, the present invention is not limited to the following embodiments. In this specification, the range "X to Y" includes X and Y and means "X or more and Y or less." Furthermore, unless otherwise specified, operations and measurements of physical properties, etc. are performed under conditions of room temperature (20 to 25°C) and relative humidity of 45 to 55% RH.
[0013] A first embodiment of the present invention comprises the following components (A) to (E): (A) Fluorine-modified silicone oil (B) Silicone wax (C) Silicone oil (excluding components (A) and (B)) (D) A compound having a hydrophilic group and a lipophilic group in one molecule, and the lipophilic group is of a double-chain type. (E) Powder The solid powder cosmetic is obtained by removing the solvent from a mixture of a cosmetic base containing the above-mentioned compound and a solvent. The solid powder cosmetic of the first embodiment exhibits good adhesion to an applicator, high adhesion of the cosmetic to the skin, long-lasting cosmetic effects, and excellent impact resistance (reduction of cracking and shrinkage after solvent removal).
[0014] The detailed mechanism by which the cosmetic material of the present embodiment exhibits the above-described effects is unknown, but is thought to be as follows: Note that the following mechanism does not in any way limit the technical scope of the present invention.
[0015] In the wet molding method, a slurry-like composition is used, the viscosity of which is reduced using a solvent when the composition is filled into a container. The solvent is ultimately removed by absorption into an absorbent pad or drying. The inventors noted that if the solvent is difficult to remove from the slurry-like composition, it can lead to shrinkage and cracking of the final solid powder cosmetic. The use of oils (A) to (C) and component (D) reduces the compatibility between the solvent and the composition, improving solvent removal, and is therefore thought to improve the impact resistance of the final solid powder cosmetic. In particular, component (A) is fluorine-modified to be water- and oil-repellent, which is thought to reduce its compatibility with hydrocarbon oils and water, which are commonly used as solvents, and significantly improve solvent removal. However, for component (A) to exert its effects, it is important to combine it with a silicone oil (see Comparative Example 6 below). This is thought to be because the silicone oil of component (C) is necessary for component (A) to be uniformly dispersed within the formulation. Furthermore, because solvent removal is good, impact resistance is improved, and there is no particular need to increase the hardness of the formulation, such as by increasing the pressing pressure during production. Therefore, it is thought that the resulting solid powder cosmetic will not harden and that the cosmetic will have good toning. With regard to the toning of the cosmetic, components (B) and (D) also play an important role, and the blending of components (B) and (D) improves the toning of the cosmetic. This is because components (B) and (D) can improve the binding between powder particles, ensuring strength without the need for high pressing pressure during production, and it is thought that the resulting solid powder cosmetic will not harden and that the cosmetic will have good toning.
[0016] Furthermore, by using component (B), which is highly compatible with components (A) and (C), the wax is dispersed evenly around the powder, which is thought to improve the durability of the cosmetic effect. Furthermore, component (D) not only has high adhesion to the powder as mentioned above, but also has good compatibility with the oils in components (A) to (C), and furthermore, it adheres well to the skin, so it is thought to play an important role in forming and maintaining a uniform cosmetic film.
[0017] As used herein, the term "solid powder cosmetic" refers to a solid cosmetic containing powder (powder) as the main component. Here, "main component" refers to a composition containing 50% or more by mass of powder (powder). In this embodiment, the powder (powder) content is preferably greater than 60% by mass, more preferably 70% or more by mass, and even more preferably 80% or more by mass. The upper limit of the powder (powder) content is 100% by mass, but taking into account other components blended into the cosmetic, it is usually 99.9% by mass or less, and may be 99.5% by mass or less, or even 99% by mass or less.

The presence of the hydrophilic and lipophilic groups allows it to interact with powders, regardless of whether or not the surface is treated with component (E), and is thought to improve the bonding strength between powders. Furthermore, because the lipophilic group is two-chain, it is possible to increase the bonding strength between powders more than with a single-chain type, and at the same time, the lipophilic chains are oriented in a certain direction, which is thought to improve functionality.
[0048] Examples of component (D) include phospholipids, N-acylamino acids or salts thereof, and behendimonium ethyl stearyl phosphate, double-chain biscarboxylate-type amphiphilic compounds (commercially available products include, for example, Gemisurf α142 (dicarboxylic acid having two lauryl groups), manufactured by Chukyo Yushi Co., Ltd.), and bispyridimonium quaternary ammonium salt-type amphiphilic compounds (commercially available products include, for example, Hygenia S-100 (3,3'-(butane-1,4-dioxydimethylene)-N,N-didecyldipyridinium dibromide), manufactured by Tama Chemical Industry Co., Ltd.).
[0049] Among these, from the viewpoints of improving impact resistance and prolonging the duration of cosmetic effects, it is preferable that component (D) be at least one selected from the group consisting of phospholipids, N-acylamino acids or salts thereof, and behendimonium ethyl stearyl phosphate.

[0051] An N-acylamino acid is an amino acid in which at least one amino group is acylated with an acyl group. In this specification, an N-acylamino acid or a salt thereof may also be referred to as an N-acylamino acid (salt).
[0052] The acyl group is preferably a saturated or unsaturated, linear, branched, or cyclic acyl group having 6 to 30 carbon atoms, more preferably a saturated or unsaturated, linear or branched acyl group having 8 to 20 carbon atoms, and even more preferably a saturated linear acyl group having 12 to 18 carbon atoms.

[0055] Behendimonium ethyl stearyl phosphate is a compound having the following structure:
[0056] [ka]
[0057] Behendimonium ethyl stearyl phosphate is a phospholipid-like compound in which a nitrogen-containing alcohol is added to a phosphate ester. Because of its structure, it has a very high affinity for the skin, while its relatively small molecular weight allows it to easily interact with powders and bond to their surfaces, helping the powders adhere evenly to the skin. Therefore, incorporating behendimonium ethyl stearyl phosphate into solid powder cosmetics makes it easier for the powder to adhere to the skin (facilitating the formation of a cosmetic film). Furthermore, behendimonium ethyl stearyl phosphate has a good balance of lipophilicity and hydrophilicity, and excellent water- and oil-repellent properties, which can contribute to improved makeup wear.
[0058] The component (D) may be used alone or in combination of two or more types.
[0059] In consideration of adhesion to the skin, the content of component (D) in the solid powder cosmetic is preferably 0.05% by mass or more, more preferably 0.1% by mass or more, and even more preferably 0.3% by mass or more. In consideration of impact resistance, the content of component (D) is preferably 5% by mass or less, more preferably 3% by mass or less, and particularly preferably 2.5% by mass or less. In a preferred embodiment of the present invention, the content of component (D) in the solid powder cosmetic is 0.05 to 5% by mass.
[0060] Component (D) may be used as a surface treatment agent for the powder of component (E). In this case, the content of component (D) is not included in the content of component (E).
[0061] The surface treatment of component (E) with component (D) can be carried out by a conventional method. For example, component (D) and the powder to be treated are added to a solvent (e.g., an alcohol such as isopropyl alcohol (IPA) or isoparaffin (e.g., IP Solvent (Idemitsu Kosan)) and stirred in a ball mill or the like. After drying, washing with water, and filtering as necessary to remove impurities, the resulting mixture is dried and pulverized to obtain the desired surface-treated powder.

[0070] The amount of the surface treatment agent to be used is preferably 0.1 to 30% by mass, more preferably 0.5 to 20% by mass, and even more preferably 1 to 10% by mass, based on the untreated powder.
[0071] The surface treatment can be carried out by a conventionally known method. For example, a surface treatment agent and powder particles to be treated are added to a solvent, stirred in a ball mill or the like, and then dried, washed with water, and filtered repeatedly as necessary to remove impurities, followed by drying and pulverization to obtain the desired surface-treated powder. Furthermore, several types of compounds that are surface treatment agents can be used simultaneously for surface treatment, or surface treatment can be carried out in advance with one compound and then with another compound.
[0072] The component (E) may be used alone or in combination of two or more types.
[0073] The content of component (E) is 50% by mass or more relative to the cosmetic, but may be 60% by mass or more, 70% by mass or more, or 80% by mass or more. In the case of surface-treated powders, the amount of the powder includes the amount of the surface treatment agent.
[0074] (Other ingredients) In addition to the above components, oils other than components (A) to (C), alcohol, preservatives, antioxidants, cosmetic ingredients, antibacterial agents, fragrances, chelating agents (such as EDTA), UV absorbers, film-forming agents, fragrances, and the like, which are commonly used in cosmetics, may also be appropriately contained within a range that does not impair the effects of the present invention. In consideration of the effects of the present invention, it is preferable that the amount of oils other than components (A) to (C) be as small as possible, and specifically, the amount of oils other than components (A) to (C) relative to the total amount of oils is preferably 30% by mass or less, more preferably 25% by mass or less, and even more preferably 20% by mass or less.
[0075] Furthermore, in the solid powder cosmetic of the present application, the water content is preferably 3% by mass or less, more preferably 1% by mass or less, and preferably substantially free of water. Here, "substantially free of water" means that the content of impurities is acceptable, for example, 0.1% by mass or less.
[0076] The solid powder cosmetic of this embodiment is obtained by removing the solvent from a mixture of a cosmetic base containing components (A) to (E) and the solvent.
[0077] The cosmetic base is prepared by stirring and mixing the above-mentioned components using a device typically used to produce powder cosmetics. More specifically, the cosmetic base is prepared by first mixing components (A) to (C), or optionally an oily component containing component (D), and, if necessary, heating and dissolving the mixture. Meanwhile, a powder containing component (E) and, optionally, a powder surface-treated with component (D) are uniformly mixed. The oily component is added to this mixture, uniformly dispersed, and then pulverized to prepare the cosmetic base.
[0078] Next, a mixture of the cosmetic base and the solvent is prepared. This mixture is usually in a slurry state. Hereinafter, the mixture of the cosmetic base containing components (A) to (E) and the solvent will also be simply referred to as the mixture.
[0079] The solvent used can be either non-volatile or volatile, but a solvent with a boiling point of 260°C or less at normal pressure is preferred. Specific examples of the solvent include aqueous solvents such as low-boiling alcohols such as water, ethyl alcohol, propyl alcohol, isopropyl alcohol, and butyl alcohol, and mixed solvents of water and low-boiling alcohols; and oily solvents such as (low-boiling) hydrocarbon oils such as isododecane, isohexadecane, and light liquid isoparaffin. These can be used alone or in combination as a mixture of two or more.
[0080] The solvent is preferably a hydrocarbon oil or an aqueous solvent, and more preferably a low-boiling hydrocarbon oil such as isododecane, isohexadecane, or light liquid isoparaffin (hydrogenated polyisobutene), as these solvents are more likely to exhibit the effects of the present invention.
[0081] The amount of solvent to be mixed is selected arbitrarily to provide fluidity for filling the pre-molded mixture into a container or tray, but it is preferable to use 10 to 200 parts by mass of solvent per 100 parts by mass of cosmetic base.Within this range, the solvent can be easily removed.
[0082] Furthermore, in this specification, fluidity refers to a state in which, when 30 g of a mixture of a cosmetic base whose main component is powder and a solvent is placed in a container ("Pill Bottle PS-6K" manufactured by Daiichi Glass Co., Ltd.) with an inner diameter of 2.47 cm, a body diameter of 4.05 cm, and an overall height of 7.4 cm, the container is sealed with the attached lid, and then tilted 90 degrees in an environment of 25°C and 1 atmosphere and left to stand for 1 minute, a portion of the mixture adheres to the inside of the lid.
[0083] The mixture obtained above is then filled into a container, such as a metal dish or a resin dish, and is preferably compression molded after filling.
[0084] Next, the solvent is removed. While the removal method is not particularly limited, it is preferable to remove the solvent by placing one or more layers of paper, cloth, or the like in contact with the powder cosmetic filled in the container during and / or after compression molding, and then allowing the solvent to be absorbed. Moderate pressure may be applied when absorbing the solvent. Furthermore, when filling a container or inner tray with a mixture of the cosmetic base and solvent, it is preferable to gently press the mixture using a pad or the like to smooth the surface. During this pressing, a porous press head or absorbent may also be used to absorb the volatile solvent. Furthermore, the solvent can also be removed by drying. The conditions for this are appropriately determined depending on the boiling point and specific heat of the solvent. For example, in the case of light liquid isoparaffin, drying is performed at 50 to 80°C for approximately 5 to 20 hours.
[0085] The solid powder cosmetic of this embodiment can be used in makeup cosmetics such as foundation, face powder, face powder (white powder), concealer, eye color (eye shadow), eyeliner, eyebrow pencil, mascara, blush, lipstick, sunscreen cosmetics, and cosmetic base; skin care cosmetics such as body powder; and preferably, the cosmetic is a makeup cosmetic such as foundation, face powder, face powder, eye color, cosmetic base, sunscreen cosmetics, or blush, in which the effects of the present application are more likely to be exhibited, and more preferably, a foundation, face powder, or face powder, which have a large application area. Furthermore, the method of use can include application by hand or finger, or by impregnating a puff, sponge, or the like with the cosmetic.
[0086] The blending amount of each component in the cosmetic base is the same as the blending amount of each component in the resulting solid powder cosmetic. [Example]
