Description

Coated Particles for Cosmetics and Cosmetics

[0001] The present invention relates to coated particles for cosmetics and cosmetics.

[0002] In order to impart beauty effects, ultraviolet protection effects, etc. to cosmetics, various powder raw materials (synthetic resin beads derived from petroleum such as nylon and silicone, and powder raw materials of natural origin, etc.) are used.

[0003] And, as a powder raw material of natural origin used for the purpose of improving the feel of use of cosmetics, cellulose acetate particles hydrophobized by coating with a metal soap-based treatment agent have been developed (Patent Document 1).

[0004] Japanese Patent Application Laid-Open No. 2022-99605

[0005] However, the hydrophobicity of the coated particles described in Patent Document 1 is not sufficient, and the compatibility between the smoothness and softness of the cosmetics using the coated particles is not sufficient, and further improvement in the feel of use is desired.

[0006] An object of the present invention is to provide coated particles for cosmetics having excellent feel of use and high hydrophobicity, and cosmetics having excellent feel of use.

[0007] As a result of intensive studies to solve these problems, the present inventors have reached the present invention. That is, the present invention is a coated particle for cosmetics having a coating layer containing a cationic surfactant (C) and an aliphatic alcohol (D) on at least a part of the surface of core particles (A) which are particles composed of a polysaccharide having glucose as a constituent unit or inorganic particles, and the molar ratio of the cationic surfactant (C) to the aliphatic alcohol (D) is 20:1 to 1:15; a cosmetic containing the coated particles for cosmetics is provided.

[0008] According to the present invention, it is possible to provide coated particles for cosmetics having excellent feel of use and high hydrophobicity, and cosmetics having excellent feel of use.

If the ratio [moles of cationic surfactant (C) / moles of aliphatic alcohol (D)] exceeds 20 / 1, the feel of the coated particles for cosmetics deteriorates, and if it is less than 1 / 15, the smooth feeling decreases. A molar ratio of 16:1 to 1:14 is more preferable.

[0033] <Coated Particles for Cosmetics> The coated particles for cosmetics of the present invention have a coating layer on at least a part of the surface of a core particle (A). Coating means a state in which a layer made of another substance is attached to the surface of the object to be coated, and the surface of the object to be coated and the layer made of the other substance may be physically attached or may be chemically bonded and integrated. The layer made of the other substance is called the coating layer. The coating layer may be one layer or two or more layers.

If the coating layer further contains an ester compound (B), the ester compound (B) may be included in any of the layers, or it may be included in all of the layers. A layer consisting of a cationic surfactant (C) and an aliphatic alcohol (D) may be laminated with a layer consisting of an ester compound (B), and either layer may be on the outside, but it is preferable that the layer consisting of the ester compound (B) is on the outside. It is preferable that there are two or more coating layers, and it is more preferable that the layer containing the ester compound (B) is the outermost layer of the coating layers.

[0034] The BET specific surface area of ​​the coated particles for cosmetic use of the present invention is 0.1 to 60 m², from the viewpoint of design freedom for cosmetic formulations and the feel of the coated particles for cosmetic use. ２It is preferably 0.2 to 60 m / g. ２ It is more preferable that the amount is 0.5 to 40 m / g. ２ It is even more preferable that it be / g.

[0035] The above BET specific surface area was determined using the fully automated BET specific surface area measuring device "Macorb® HM model-1201" (manufactured by Mountec Co., Ltd.) in accordance with JIS Z 8830:2013, by the carrier gas method using nitrogen gas as the adsorbate.

[0036] The coated particles for cosmetics of the present invention may appropriately contain components other than the core particles (A), cationic surfactant (C), aliphatic alcohol (D), and the ester compound (B), as long as they do not impede the effects of the present invention.

[0037] <Method for Manufacturing Coated Particles for Cosmetics> The coated particles for cosmetics of the present invention can be manufactured by mixing core particles (A), a cationic surfactant (C), an aliphatic alcohol (D), and optionally an ester compound (B). The manufacturing method can be a dry method in which the coating is performed without using a solvent, or a wet method in which the core particles (A) are coated using a cationic surfactant (C), an aliphatic alcohol (D), and optionally an ester compound (B) dispersed or dissolved in a solvent. From the viewpoint of environmental considerations and the freedom of the concentration and type of coating agent, it is preferable that the coated particles for cosmetics of the present invention be manufactured by the dry method.

[0038] A dry method for producing coated particles for cosmetics includes a method in which core particles (A), a cationic surfactant (C), an aliphatic alcohol (D), and optionally an ester compound (B) are mixed without the use of a solvent using a stirrer (mill mixer, pencil mixer, planetary mixer, disper mixer, homo mixer, intensive mixer, ribbon blender, jet mill, ball mill, kneader, extruder, mortar and pestle, etc.), a pulverizer, a mixer and a disperser, etc., thereby coating the core particles (A) with the cationic surfactant (C), an aliphatic alcohol (D), and optionally an ester compound (B). There are no particular restrictions on the order of mixing; the core particles (A), cationic surfactant (C), aliphatic alcohol (D), and optionally an ester compound (B) may be added and mixed simultaneously, or the core particles (A), cationic surfactant (C), aliphatic alcohol (D), and optionally an ester compound (B) may be added and mixed in order. From the viewpoint of improving the surface hydrophobicity of the coated particles for cosmetics, it is preferable to heat a cationic surfactant (C) and an aliphatic alcohol (D) at 75 to 120°C to dissolve them uniformly, then cool them to 5 to 60°C to obtain a particulate composition, and then stir with core particles (A) to form a coating layer containing the particulate composition. Alternatively, it may be mixed with an ester compound (B) thereafter to further form a coating layer consisting of the ester compound (B). In the dry method, the coating treatment may be carried out while applying energy such as heat, ultraviolet light, laser, and electromagnetic waves.

[0039] In the dry method, the mixing time can be adjusted according to the machine used and the processing volume, and it is preferable to mix until the surface of the cosmetic-coated particles exhibits hydrophobicity. Specifically, it is preferable to mix until the "degree of surface hydrophobicity of cosmetic-coated particles (%)" measured by the following method is 90% or higher. The following measurement utilizes the phenomenon that when the degree of surface hydrophobicity is high, even when the coated particles are mixed with water, the number of coated particles that float on the water surface without dispersing in the water increases. 0.1 g of cosmetic-coated particles is placed in a 30 mL beaker containing 24.9 g of purified water, and after stirring for 30 minutes using a magnetic stirrer, 1 to 2 mL of the cosmetic-coated particles dispersed in the purified water, avoiding the particles on the water surface, is collected together with the purified water as a cosmetic-coated particle dispersion using a syringe (capacity 5 mL). The weight of the collected cosmetic-coated particle dispersion and the dry weight after drying the entire amount of the collected cosmetic-coated particle dispersion at 105°C for 1 hour using a forward-wind dryer are measured. Substitute the measured weight into the following formula to determine the "degree of surface hydrophobicity of the cosmetic-coated particles (%)". Degree of surface hydrophobicity of cosmetic-coated particles (%) = [1 - {(25 × dry weight of recovered cosmetic-coated particle dispersion (g)) / (weight of recovered coated particle dispersion (g)) / 0.1}] × 100

[0040] Furthermore, the mixing temperature in the dry process is preferably between 0°C and 50°C.

[0041] A method for producing coated particles for cosmetics by a wet method includes a method in which core particles (A) are mixed with a cationic surfactant (C), an aliphatic alcohol (D), and optionally an ester compound (B) dissolved or dispersed in a solvent (water and / or an organic solvent), thereby coating the core particles (A) with the cationic surfactant (C), the aliphatic alcohol (D), and optionally an ester compound (B).

[0042] In the wet process, organic solvents are preferred, including ester oils, hydrocarbon oils, fatty acid oils, aliphatic alcohol oils, and silicone oils. Ester oils, hydrocarbon oils, fatty acid oils, aliphatic alcohol oils, and silicone oils are also used as ingredients in cosmetics, so even if they remain on the coated particles for cosmetics, there is little risk of skin irritation. As for ester oils, ester oils known as raw materials for cosmetics can be used, such as liquid oils and synthetic ester oils described in Japanese Patent Application Publication No. 2020-26432, and preferably trysters of caprylic acid and capric acid with glycerin, diesters of caprylic acid and capric acid with propanediol, and monoesters of lauric acid with 1-hexanol can be used. As for hydrocarbon oils, hydrocarbon oils known as raw materials for cosmetics can be used, such as hydrocarbon oils such as squalane described in Japanese Patent Application Publication No. 2020-26432, and preferably decane, dodecane, isododecane, and squalane can be used. As the fatty acid oil, known fatty acid oils used as raw materials for cosmetics can be used, and saturated fatty acids with 9 or fewer carbon atoms are preferably used. As the aliphatic alcohol oil, known aliphatic alcohol oils used as raw materials for cosmetics can be used, and saturated aliphatic alcohols with 11 or fewer carbon atoms are preferably used. As the silicone oil, known silicone oils used as raw materials for cosmetics can be used, and silicone oils described in Japanese Patent Application Publication No. 2020-26432 can be used. Among these, ester oils and hydrocarbon oils are preferred, and monoesters of lauric acid and 1-hexanol, decane, dodecane, isododecane, and squalane are particularly preferred. The amount of solvent is preferably 40% by weight or more relative to the weight of the core particles (A). The total weight ratio of the cationic surfactant (C), aliphatic alcohol (D), and optionally ester compound (B) to the solvent is preferably 0.1 to 20% by weight, and more preferably 1 to 5% by weight. The weight ratio of the treatment solution, which contains a cationic surfactant (C), an aliphatic alcohol (D), and optionally an ester compound (B), dissolved or dispersed in a solvent, to the core particles (A) is preferably 30:70 to 99:1.The apparatus used in the wet method is not particularly limited as long as it can perform stirring and heating.

[0043] In the wet method, it is preferable to have a step of removing the solvent. As a method for removing the solvent, the solvent is vaporized and distilled off from a mixture of core particles (A), cationic surfactant (C), aliphatic alcohol (D), solvent, and optionally ester compound (B) by heating and / or reducing the pressure. And a method of extracting and removing the solvent from the mixture, etc. are mentioned. As a method of extracting and removing the solvent from the mixture, other organic solvents [ether solvents (diethyl ether, tetrahydrofuran, etc.), and hydrocarbon solvents (toluene, hexane, etc.), etc.] other than the solvent contained in the mixture are mixed with the mixture to extract the solvent contained in the mixture into the other solvent. And a method of extracting the solvent into the other solvent, etc. are mentioned.

[0044] The solvent remaining in the coated particles for cosmetics obtained by the wet method is preferably 20% by weight or less, more preferably 5% by weight or less based on the weight of the coated particles for cosmetics. The weight of the solvent remaining in the coated particles for cosmetics is obtained by mixing the coated particles for cosmetics with methanol or hexane of the same weight as the coated particles for cosmetics at 25°C for 30 minutes, filtering off the solid part, and calculating the ratio of the evaporation residue of the filtrate to the dry weight of the solid part.
