JP7720705B2 - Stick-type cosmetics - Google Patents

Description

The present invention relates to a stick-type cosmetic product.

Many solid cosmetics containing large amounts of powder have been developed that are poured into jar containers or press-molded in metal plates, but molding them into a stick shape has been considered difficult due to poor fluidity during molding. Meanwhile, stick-shaped cosmetics are preferred in the market for their portability and convenience of being able to apply them without getting your hands dirty, and there is a demand for the development of stick-shaped cosmetics that combine a smooth finish with a high powder content. Existing technologies for solid cosmetics containing large amounts of powder include stick-shaped cosmetics that contain 30-60% by weight of powder and 5-40% of spherical powder, which have good usability (spreadability) and reduced breakage during use (e.g., Patent Document 1), and a technology that achieves a beautiful and smooth makeup look by combining a crosslinked organopolysiloxane, powder, and a fluid oily component (e.g., Patent Document 2).

Japanese Patent Application Laid-Open No. 2002-187813 Japanese Patent Application Laid-Open No. 2005-206497

However, although the former is in stick form, it does not have the smooth feel of powder cosmetics, and the latter technology is unsatisfactory in terms of moldability in stick form and smooth feel in use. In light of the above circumstances, the objective of the present invention is to provide a stick-type cosmetic that combines a smooth finish, smooth spreadability, good adhesion, and other usability characteristics.

In light of this situation, the inventors conducted extensive research to solve the above-mentioned problems, and as a result, they discovered that a stick-type cosmetic containing 30 to 50% by mass of powder containing spherical powder in a specific blend ratio, cross-linked organopolysiloxane, wax, and silicone oil has excellent moldability, a smooth finish, and smooth spreadability, leading to the completion of the present invention.

That is, the present invention includes the following.
[1]
The following components (A) to (D):
Component (A) powder 30-50% by mass
Component (B) Crosslinked organopolysiloxane Component (C) Wax 3 to 10% by mass
A stick-type cosmetic preparation containing component (D) a liquid oil containing silicone oil, wherein the spherical powder contained in component (A) accounts for 60 mass % or more of component (A).
[2]
The silicone oil contained in the component (D) is 60 to 90% by mass in the component (D).
[3]
The spherical powder contained in the component (A) includes two or more types, one having an average particle size of less than 10 μm and the other having an average particle size of 10 μm or more.
[4]
The spherical powder contained in the component (A) includes substantially spherical powder having irregularities on the surface.

The present invention makes it possible to provide a stick-type cosmetic product that combines a smooth finish, smooth spreadability, and good adhesion, making it easy to use.

The present invention will be described in detail below. In the present specification, the term "mass %" may be simply referred to as "%", but this refers to mass % and the term "to" refers to a range including the numerical values before and after it.
The average particle size in this application is measured as a volume average particle size (D50) using a laser diffraction/scattering particle size distribution analyzer (LA-910, manufactured by Horiba, Ltd.).

The powder component (A) of the present invention can be any powder acceptable as a cosmetic ingredient, and is not particularly limited. Specific examples include inorganic powders such as titanium oxide, black titanium oxide, cerium oxide, konjo (ferrous metal), ultramarine, red iron oxide, yellow iron oxide, black iron oxide, zinc oxide, aluminum oxide, silicic anhydride, magnesium oxide, zirconium oxide, magnesium carbonate, calcium carbonate, calcium sulfate, chromium oxide, chromium hydroxide, carbon black, aluminum silicate, magnesium silicate, magnesium aluminum silicate, mica, synthetic mica, sericite, talc, kaolin, silicon carbide, barium sulfate, and boron nitride; Red No. 201, Red No. 202, Red No. 205, Red No. 226, Red No. 228, Orange No. 203, and Orange No. 20; Organic pigment powders such as No. 4, Blue No. 404, Yellow No. 401, Black No. 401, Brown No. 201, Purple No. 401, Blue No. 1, Blue No. 2, Blue No. 203, Blue No. 205, Green No. 3, Green No. 201, Green No. 204, Green No. 205, Green No. 401, Green No. 402, Yellow No. 4, Yellow No. 5, Yellow No. 202 (1), Yellow No. 202 (2), Yellow No. 203, Yellow No. 402, Yellow No. 403 (1), Yellow No. 406, Yellow No. 407, Orange No. 205, Orange No. 402, Red No. 2, Red No. 3, Red No. 102, Red No. 104 (1), Red No. 105 (1), Red No. 106, Red No. 227, Red No. 230 (1), Red No. 231, Red No. 401, Red Organic pigment powders such as zirconium, barium or aluminum lakes such as Color No. 502, Red No. 503, Red No. 504, Red No. 506, etc., bismuth oxychloride, titanium oxide coated mica, iron oxide coated mica, iron oxide coated mica titanium, organic pigment coated mica titanium, titanium oxide coated glass flakes, aluminum powder, glittering powders such as polyethylene terephthalate laminated powder, nylon powder, polymethyl methacrylate powder, acrylonitrile-methacrylic acid copolymer powder, vinylidene chloride-methacrylic acid copolymer powder, polyethylene powder, polystyrene powder, (dimethicone/vinylidene Examples of suitable surface treatment agents include organic powders such as (vinyl dimethicone/methicone silsesquioxane) crosspolymer powder, (diphenyl dimethicone/vinyl diphenyl dimethicone/silsesquioxane) crosspolymer powder, polymethylsilsesquioxane powder, polyurethane powder, wool powder, silk powder, and N-acyl lysine; and composite powders such as fine particle titanium dioxide-coated mica titanium, fine particle zinc oxide-coated mica titanium, barium sulfate-coated mica titanium, titanium oxide-containing silica, and zinc oxide-containing silica. One or more of these may be used. These powders may also be surface-treated. Surface treatment agents are not particularly limited as long as they are commonly used in cosmetics, and commonly known agents such as fluorine compounds, silicone compounds, hydrocarbons, higher fatty acids, higher alcohols, metal soaps, surfactants, and water-soluble polymers may be used.

The spherical powder contained in component (A) includes not only true spheres but also nearly spherical, ellipsoidal, and nearly spherical spheres with irregularities on part or all of their surface, with a major axis/minor axis ratio preferably ranging from 1.5/1 to 1/1, more preferably from 1.2/1 to 1/1. Furthermore, as long as the powder is spherical, it can be composed entirely of a single component, a core-shell type in which the inner core and outer shell are composed of different components, a powder with different components dispersed inside, a hollow powder with an internal cavity, or even a powder containing or impregnated with beneficial ingredients, without any particular limitations. Specific examples include organic powders such as polyurethane powder, cellulose powder, nylon powder, polymethyl methacrylate powder, polyethylene powder, and silicone resin powder, and inorganic powders such as silica powder and aluminosilicate powder. Commercially available products include KSP-100 (Shin-Etsu Chemical Co., Ltd.), TOSPEARL 3000A (Momentive Performance Materials Japan), Sunsphere NP-100 (AGC Si-Tech Co., Ltd.), and TOSPEARL 150KA (Momentive Performance Materials Japan).

The average particle size of the spherical powder contained in component (A) is not particularly limited, but those with an average particle size of 2 to 30 μm are preferably used. Furthermore, it is preferable to combine spherical powders with an average particle size of less than 10 μm (small spherical powders) and spherical powders with an average particle size of 10 μm or more (large spherical powders), and it is more preferable for the small spherical powders to be 5 μm or less. The content ratio of large to small spherical powders is preferably 0.8:1 to 1.2:1, and more preferably 0.8:1 to 1:1. This improves the loosening of the cosmetic during use, achieving a smooth finish and smooth spreadability.

Including spherical powders that are not only perfectly spherical but also roughly spherical can further improve the loosening of the cosmetic and enhance smooth spreadability. Among these, roughly spherical particles with a starch-like shape and micro-projections covering the entire particle surface are preferred. These have multiple micro-projections covering the entire surface of a spherical core particle, and the projections are not easily chipped off. The circumscribed circle connecting the vertices of the projections is roughly spherical, and the average particle diameter refers to the diameter of the circumscribed circle. In the present invention, those with a polyorganosiloxane surface are preferably used because they are compatible with the silicone oil contained in components (B) and (C), which will be described later. Commercially available products include TOSPEARL 150KA (manufactured by Momentive Performance Materials), in which both the core spherical particle and the protrusions are polymethylsilsesquioxane, and Silcrusta MK03 (manufactured by Nikko Rica Corporation), in which the core spherical particle is a methyl methacrylate crosspolymer and the surface protrusions are polymethylsilsesquioxane.

The content of component (A) in the present invention in the cosmetic is 30-50%, more preferably 35% or more, even more preferably 40% or more, and preferably 45% or less. This range is favorable in terms of a smooth feel when used and the moldability of the stick. Furthermore, the spherical powder contained in component (A) is 60% or more in component (A), more preferably 65% or more, and even more preferably 70% or more. This range is favorable in terms of a smooth finish.

The crosslinked organopolysiloxane component (B) of the present invention is a polymer obtained by crosslinking an organopolysiloxane and having a partial three-dimensional crosslinked structure. For example, it can be obtained by addition polymerization of an organohydrogenpolysiloxane containing an average of 1.5 or more silicon-bonded hydrogen atoms per molecule, as shown in (a) below, with a compound having an average of 1.5 or more vinyl reactive sites per molecule, as shown in (b).

(a) is an organohydrogenpolysiloxane composed of at least one structural unit selected from the group consisting of _SiO2 units, _HSiO1.5 units, _RSiO1.5 units, RHSiO units, _R2SiO units, _{R3SiO0.5 units} , and _RHSiO0.5 units (wherein R is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms, excluding aliphatic unsaturated groups. Examples of monovalent hydrocarbon groups include alkyl groups such as methyl, ethyl, and propyl; aryl groups such as phenyl and tolyl; aliphatic unsaturated groups such as vinyl; aralkyl groups in which a hydrogen atom of methyl, ethyl, or propyl is substituted with an aryl group such as phenyl or tolyl; cycloalkyl groups such as cyclohexyl; halogenated hydrocarbon groups containing a fluoro group; and hydrocarbon groups containing an ethylene oxide group), and containing an average of 1.5 or more hydrogen atoms bonded to silicon atoms per molecule.

(b) is one or more selected from the following (b-1) to (b-3):
(b-1) is an organopolysiloxane composed of at least one structural unit selected from the group consisting of _SiO2 units, (CH2=CH) _SiO1.5 units, _RSiO1.5 units, R(CH2=CH)SiO units, RSiO _units , _RSiO0.5 units, and R(CH2=CH)SiO0.5 units (wherein R is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 30 carbon atoms, excluding aliphatic unsaturated groups. Examples of monovalent hydrocarbon groups include alkyl groups such as methyl, ethyl, and propyl; aryl groups such as phenyl and tolyl; aliphatic unsaturated groups such as vinyl; aralkyl groups in which a hydrogen atom of methyl, ethyl, or propyl is substituted with an aryl group such as phenyl or tolyl; cyclohexyl groups; halogenated hydrocarbon groups containing a fluoro group; and hydrocarbon groups containing an ethylene oxide group), and containing an average of 1.5 or more vinyl groups bonded to silicon atoms per molecule.
(b-2) is a polyoxyalkylene represented by the following general formula (I).
C _m H _2m-1 O(C ₂ H ₄ O) _h (C ₃ H ₆ O) _i C _m H _2m-1 ...(I)

(where n is an integer of 2 to 6, and j is an integer of 1 or more.)

Specific examples of component (B), by INCI name, include (dimethicone/vinyl dimethicone) crosspolymer, (dimethicone/phenyl vinyl dimethicone) crosspolymer, (dimethicone/lauryl dimethicone) crosspolymer, (dimethicone/(PEG-10/15)) crosspolymer, (PEG-15/lauryl dimethicone) crosspolymer, (dimethicone/polyglycerin-3) crosspolymer, and (lauryl dimethicone/polyglycerin-3) crosspolymer.
Although the crosslinked organopolysiloxane can be incorporated in a solid state, it is preferable in terms of film uniformity to have it present in the cosmetic in a state swollen with component (A) or another oil. Furthermore, this crosslinked organopolysiloxane is often sold commercially as a mixture with an oil, in which case it is in a state swollen with the oil. This commercially available product can also be used in the present invention. Examples of commercially available products include mixtures of crosslinked methylpolysiloxane and dimethylpolysiloxane such as KSG-6, KSG-16, and KSG-016F, mixtures of crosslinked methylpolysiloxane and decamethylcyclopentasiloxane such as KSG-7 and KSG-15, and KSG-310 and KSG-710 (all manufactured by Shin-Etsu Chemical Co., Ltd.).

The content of component (B) in the cosmetic is preferably 3% or more, more preferably 4% or more, even more preferably 5% or more, and preferably 9% or less, more preferably 8% or less, and even more preferably 7% or less. This range provides a smooth feel when used and is favorable in terms of stick formability.

The wax component (C) used in the present invention is not particularly limited as long as it is suitable for use in cosmetics, and may be either a synthetic hydrocarbon wax or a natural or synthetic wax. Its melting point is preferably 70°C or higher, more preferably 80°C or higher, in view of its light, non-sticky feel and high-temperature stability. Specific examples include paraffin wax, ceresin wax, ozokerite wax, microcrystalline wax, Fischer-Tropsch wax, polyethylene wax, ethylene-propylene copolymer, candelilla wax, carnauba wax, beeswax, rice wax, Japan wax, jasmine wax, montan wax, stearyl-modified methylpolysiloxane, and behenyl-modified methylpolysiloxane, and one or more of these may be used.

The content of component (C) in the present invention is 3-10%, but is more preferably 4% or more in the cosmetic, particularly preferably 5% or more, and is preferably 8% or less, more preferably 7% or less, and particularly preferably 6% or less. This range is preferable because it can be molded into a stick shape and can be spread smoothly.

Component (D), the liquid oil of the present invention, is an oil agent that is liquid at 25°C and contains silicone oil. Component (D) can be any oil that is acceptable as a cosmetic ingredient, and is not particularly limited. Specific examples include silicone oils, as well as hydrocarbons, fats and oils, hydrogenated oils, ester oils, fatty acid oils, and fluorine-based oils, regardless of their origin, such as animal oils, vegetable oils, or synthetic oils. Specific examples include silicone oils such as methylpolysiloxane and phenyl-modified silicone; hydrocarbons such as liquid paraffin and squalane; fats and oils such as olive oil and jojoba oil; ester oils such as isotridecyl isononanoate and triethylhexanoin; fatty acids such as isostearic acid and oleic acid; and fluorine-based oils such as perfluoropolyether. One or more of these can be used.

The silicone oil contained in component (D) is preferably present in an amount of 60 to 90% in (D) in terms of smooth spreadability and a light feel when used. Examples of such silicone oils include dimethylpolysiloxane, phenyl-modified silicone oil, and fluoro-modified silicone. Furthermore, a viscosity of 6 to 100 mPa·s at 25°C is preferred in terms of smooth spreadability. Commercially available products include KF-96-6cs, KF-96-10cs, KF-96-20cs, and KF-96-100cs (all manufactured by Shin-Etsu Chemical Co., Ltd.).

The liquid oil other than silicone oil (component (D)) preferably contains an ester oil with a weight-average molecular weight of 500 or less, as this oil has good compatibility with silicone oil and component (C) and allows for the formation of a uniform cosmetic film. Specific examples include isotridecyl isononanoate, triethylhexanoin, and cetyl 2-ethylhexanoate. Commercially available products include Salacos 913 (The Nisshin Oillio Group, Ltd.), SUPER REFINED CRODAMOL TN-LQ-(JP) (Croda Japan Co., Ltd.), MYRITOL GTEH (BASF Japan Ltd.), T.I.O (TAIWAN) (The Nisshin Oillio Group, Ltd.), Salacos 816T (The Nisshin Oillio Group, Ltd.), and CETIOL SN-1 (BASF Japan).

The content of component (D) in the present invention is not particularly limited, but is preferably 35% or more in the cosmetic, more preferably 40% or more, even more preferably 45% or more, and preferably 60% or less, more preferably 55% or less, and even more preferably 50% or less. Within this range, a good product can be obtained in terms of providing a smooth feel when used.

In addition to the above-mentioned components (A) to (D), the stick-type cosmetic preparation of the present invention may contain components commonly used in cosmetics, such as coloring components, surfactants, aqueous components, anti-fading agents, antioxidants, defoaming agents, cosmetic ingredients, preservatives, and fragrances, to the extent that the effects of the present invention are not impaired.

Any surfactant commonly used in cosmetics can be used, including nonionic surfactants, anionic surfactants, cationic surfactants, and amphoteric surfactants. Examples include esters such as glycerin fatty acid esters, polyglycerin fatty acid esters, propylene glycol fatty acid esters, sorbitan fatty acid esters, sorbitol fatty acid esters, and sucrose fatty acid esters, as well as their alkylene glycol adducts; polyoxyalkylene alkyl-co-modified silicones; and polyether-modified silicones; fatty acids and their salts that are paste-like to solid at 25°C, such as stearic acid and lauric acid; anionic surfactants such as polyoxyethylene alkyl ether sulfates, polyoxyethylene alkyl ether phosphates, amino acid types, sulfate ester types, sulfonate types, and phosphate ester types; cationic surfactants such as alkylamine salts, polyamine and alkanolamine fatty acid derivatives, and alkyl quaternary ammonium salts; and amphoteric surfactants such as betaine types and lecithin.

The aqueous component may be any component that is soluble in water, and may contain, in addition to water, other moisturizing agents such as glycols such as propylene glycol, 1,3-butylene glycol, dipropylene glycol, and polyethylene glycol; glycerols such as glycerin, diglycerin, and polyglycerin; plant extracts such as aloe vera, lavender, and rose; water-soluble polymers such as sodium hyaluronate, gum arabic, sodium alginate, carrageenan, celluloses, carboxyvinyl polymers, alkyl-added carboxyvinyl polymers, and sodium polyacrylate; and proteins, mucopolysaccharides, collagen, elastin, and keratin.
Examples of antioxidants include α-tocopherol and ascorbic acid, examples of cosmetic ingredients include vitamins, anti-inflammatory agents, and herbal medicines, and examples of preservatives include paraoxybenzoic acid esters, phenoxyethanol, and 1,2-pentanediol.

The stick-type cosmetic preparation of the present invention can achieve a smooth feel even without containing a volatile oil. From the standpoint of feel, it is desirable that the cosmetic contain no more than 5% of a volatile oil, and even more preferably no more than 1%. A volatile oil is an oil having a boiling point of 260°C or less at normal pressure.

The stick-type cosmetic of the present invention is a solid stick-type cosmetic, so long as the oily component is the continuous phase. There are no particular limitations on the shape, and it can be cylindrical, prismatic, polygonal, or any other shape. It is optimal for use as a cosmetic if the diameter of the circumscribed circle of the base is 8 to 25φ and the length is 4 to 6 cm or more.

The method for producing the stick-type cosmetic preparation of the present invention is not particularly limited, and a general production method can be used. For example, the stick-type cosmetic preparation can be obtained by, without particular limitation, heating and uniformly mixing the oily components containing components (B) to (D), followed by uniformly mixing component (A) and other components, filling the mixture into a container, and cooling and solidifying. In the present invention, it is preferable to pour the cosmetic preparation containing components (A) to (D) into a mold in a heated state, and then cooling and solidifying the cosmetic preparation to obtain the stick-type cosmetic preparation.

The present invention will be described in detail below with reference to examples, but the present invention is not limited to these examples.
