Description

The present invention relates to an oil-based composition or cosmetic.

Skin care cosmetics and makeup cosmetics come in a variety of formulations, including liquid and solid, and much research has been done to improve the sensation when applied and create more beautiful skin. In particular, makeup cosmetics have a difficult problem of balancing UV blocking ability, dispersibility of pigments such as metal oxides, and sensation during and after application. Meanwhile, crosslinked organopolysiloxane elastomers, which have unique sensations and makeup effects, have been investigated for incorporation into various formulations, including emulsion cosmetics.
Specifically, for example, Patent Document 1 proposes a cosmetic preparation that contains a surface-coated powder obtained by coating the surface of a powder with a solution of pulverized silicone elastomer obtained by applying shear force to a silicone elastomer dispersed in a dispersion medium to pulverize agglomerates, thereby providing a moist feel, a smooth and uniform finish, and excellent cosmetic staying power.
Furthermore, for example, Patent Document 2 proposes a water-in-oil emulsion cosmetic that reduces the visibility of pores over time, reduces uneven streaking upon application, increases covering power, and provides a uniform, natural finish by combining a specific titanium oxide, a cross-linked organopolysiloxane, and a spherical silicone elastic powder in specific amounts.
Furthermore, Patent Document 3 proposes a lipstick composition that uses a titanium oxide-coated plate-like inorganic powder as a pearling agent, combines this with a red iron oxide pigment, and further uses a partially crosslinked polyoxyalkylene-modified polyorganosiloxane, thereby achieving good dispersibility of the pearling agent and red iron oxide, giving the stick a vivid pearly appearance, and being non-gritty and providing an excellent feel when applied.

However, for example, in Patent Document 1, an aqueous dispersion of a silicone polymer is prepared in advance and then coated onto the surface of the powder to achieve a uniform treatment. However, this requires a procedure for preparing the dispersion in advance, and there are cases where an emulsifier is required as an additive, which has drawbacks in terms of efficient coating and uniformity of incorporation into the composition.
For example, in Patent Document 2, although there is an effect of making the streaky unevenness of a specific titanium oxide less noticeable, the point of view that the surface-coated powder in advance coated with a crosslinked organopolysiloxane as in the present invention suppresses the aggregation of titanium oxide was not found. In addition, it was not satisfactory in terms of spreadability. Furthermore, it was not possible to suppress the aggregation of the crosslinked organopolysiloxane itself during long-term storage.
Furthermore, the technique disclosed in Patent Document 3 was also unsatisfactory in terms of pigment dispersibility and aggregation of the crosslinked organopolysiloxane.
Therefore, an object of the present invention is to provide an oil-based composition and/or cosmetic which has improved dispersibility of the crosslinked organopolysiloxane itself and dispersibility of colored powder, and which provides a soft feel when applied and an appropriate fit.

In view of this situation, the inventors conducted extensive research and discovered that by using a powder in which spherical powder is uniformly surface-coated with a cross-linked organopolysiloxane elastomer, it is possible to suppress the aggregation of colored powder with an average particle size of 0.01 to 1.0 μm in a liquid oil at 25°C and maintain the dispersibility of the cross-linked organopolysiloxane elastomer itself, thereby achieving excellent multifaceted dispersibility improvement effects, a soft feel when applied to the skin, a coating film that forms naturally and without a sense of discomfort, and an excellent, appropriate fit, which led to the completion of the present invention.

Preferred embodiments of the present invention will be described in detail below. However, the present invention is not limited to the following preferred embodiments, and can be freely modified within the scope of the present invention.

The shape of the crosslinked organopolysiloxane elastomer of component (a1) in component (A) used in the present invention is not important. The effect is not significantly impaired even if it is spherical or nearly spherical. In order to uniformly coat the substrate surface, it is preferable that the minimum unit size of component (a1) is smaller than the average particle size of the spherical powder (a2).

It is preferable to adjust the pressure during treatment depending on the hardness of the particles. In particular, silica is more preferred because it is easy to maintain its shape during treatment. In addition, a composite containing an inorganic powder such as a metal oxide or an organic powder such as a pigment inside may be used, and the internal structure is not particularly limited.

The component (a2) used in the present invention may be surface-coated or untreated. In other words, in the component (A), the component (a1) and the component (a2) may be in direct contact with each other. The surface-coated powder (A) may be treated with the following treatments. Specifically, the following treatments may be used in combination: silicone treatment, pendant treatment, silane coupling agent treatment, titanium coupling agent treatment, fatty acid or its salt treatment, acylated amino acid treatment, inorganic compound treatment, etc., and one or more of them may be used in combination.

The average particle size of component (a2) in component (A) used in the present invention has a lower limit of 0.5 μm or more, preferably 1 μm or more, more preferably 3 μm or more, and even more preferably 5 μm or more. The upper limit is 50 μm or less, preferably 40 μm or less, more preferably 30 μm or less, and even more preferably 20 μm or less. Also, 0.5 to 50 μm is preferable, more preferably 3 to 40 μm, and even more preferably 5 to 30 μm. This range is preferable because aggregation and destruction are less likely to occur during coating as component (A), and the dispersibility of powder (B) in the oil-based composition of the present invention can be increased, and appropriate settling can be obtained.

In the component (A) used in the present invention, the ratio of the average particle diameter D50(A) of component (A) to the average particle diameter D50(a2) of component (a2), D50(A)/D50(a2), is not particularly limited, but D50(A)/D50(a2) is preferably 4.0 or less, more preferably 3.5 or less, even more preferably 3.0 or less, and even more preferably 2.0 or less. In this range, the lack of coagulation is more excellent, making it easier to maintain uniform adhesion. Note that if it is less than 1.0, component (a2) may be destroyed by coating, so it is preferable that it is 1.0 or more. Note that dry coating is preferable as a coating method that is likely to fall within this range. Specific examples will be described in the examples.

The content of component (a2) in component (A) used in the present invention is not particularly limited as long as it contains component (a1) and components (a3) and (a4) described below and can maintain a spherical shape, but the lower limit is preferably 65% or more, more preferably 70% or more, and even more preferably 75% or more. The upper limit is preferably 99.9% or less, more preferably 98% or less, and even more preferably 95% or less. These ranges are preferable from the viewpoint of improving dispersibility.

The surface-coated powder (A) used in the present invention may further contain (a3) a non-volatile silicone oil. Component (a3) is a non-volatile oil having an organopolysiloxane skeleton that is usually used in cosmetics, and is a non-crosslinked silicone oil that may be liquid, paste, or solid at room temperature. Specific examples include linear, branched, and cyclic dimethicone, phenyl-modified silicones such as phenyl trimethicone and diphenyl dimethicone, stearyl dimethicone, stearoxy dimethicone, alkyl (C30-45) methicone, and alkyl-modified silicones such as (acrylates/stearyl acrylate/dimethicone methacrylate) copolymer, and alkoxy-modified silicones. The dynamic viscosity (mm ² /s) of dimethicone and phenyl-modified silicone at room temperature of 25°C is not particularly limited, but the lower limit is preferably 6 mm ² /s or more, more preferably 50 mm ² /s or more, and even more preferably 100 mm ² /s or more, and the upper limit is preferably 10,000 mm ² /s or less, more preferably 5,000 mm ² /s or less, and even more preferably 1,000 mm ² /s or less. The alkyl-modified silicone may have a melting point of 10 to 70°C, and may be subjected to a heating process during surface treatment. Specifically, alkyl-modified silicones such as stearyl dimethicone and (acrylates/stearyl acrylate/dimethicone methacrylate) copolymer are preferred. This component is preferred in that it can adjust the soft feel of component (a1) and adjust the adhesion to the surface of component (a2). It should be noted that these may be used alone or in combination of two or more kinds. The method of treating component (a3) is not particularly limited and may involve coating the surface of component (a2) with component (a1) and then adding component (a3) to further coat the surface, or may involve previously mixing components (a1) and (a3) and then coating the surface of component (a2). However, from the viewpoint of appropriate settling, it is preferable to previously mix components (a1) and (a3) uniformly and then treat the mixture.

The content of component (a3) in the surface-coated powder (A) used in the present invention is not particularly limited, but the mass ratio of component (a3) to component (a1) in component (A), that is, the mass ratio (a3)/(a1), is preferably 0.01 to 1.00, more preferably 0.03 to 0.70, and even more preferably 0.07 to 0.30. This range is preferable from the viewpoint of a soft feel and appropriate fit.

Component (A) used in the present invention may further contain, as component (a4), one or more selected from esters, fatty acids or their salts, ceramides, and phospholipids, each having a hydrocarbon group with 14 to 45 carbon atoms. These components are non-volatile. The hydrocarbon group with 14 to 45 carbon atoms may be linear or branched, saturated or unsaturated, and there is no particular restriction. If the chain length of the hydrocarbon group is within this range, it is preferable because it has a soft feel and excellent adhesion while having little cohesion, and it is even more preferable because it improves the cosmetic durability. In particular, a hydrocarbon group with 16 to 24 carbon atoms is more preferable because it is easier to balance the soft feel and adhesion of the above effects.

The component (a4) that can be used in the present invention will be specifically described below.

Among these, stearic acid, palmitic acid, oleic acid, isostearic acid, and linoleic acid are preferred from the viewpoint of adhesion. There are no particular limitations on the salt.
(Ceramide)
Ceramide is an amphiphilic substance that has the common property of having a lipid in the body or a structure similar thereto, that is, a long-chain alkyl structure and a hydrophilic group.It may be a natural extract or a synthetic product as long as it can be used in normal cosmetics, and specifically, it can be exemplified by natural ceramides such as sphingosine, phytosphingosine, and their long-chain fatty acid amides, such as ceramide EOP, ceramide NS, ceramide NG, ceramide NP, and ceramide AP, sphingophospholipids such as sphingomyelin and phytosphingomyelin, which are phospholipid derivatives of sphingosine and phytosphingosine, sphingoglycolipids and phytosphingolipids such as cerebrosides and gangliosides, which are glycosides thereof, and the like.Among them, natural ceramides are preferred, and ceramide NG is more preferred.
(Phospholipids)
Phospholipids refer to those having a structure in which fatty acids and phosphoric acid are bound to a central skeleton of glycerin or sphingosine, and further, alcohol is ester-bound to the phosphoric acid. Fatty acids constituting phospholipids include saturated and unsaturated carboxylic acids having 7 to 22 carbon atoms, preferably 14 to 20 carbon atoms. Furthermore, alcohols constituting phospholipids often contain nitrogen, and examples of such alcohols include choline, ethanolamine, inositol, and serine.

The content of component (a4) in component (A) used in the present invention is not particularly limited. The lower limit is preferably 0.005% or more, more preferably 0.01% or more, and even more preferably 0.05% or more. The upper limit is preferably 5.0% or less, more preferably 3.0% or less, and even more preferably 1.0% or less. Also, 0.005 to 5.0% is preferable, 0.01 to 3.0% is more preferable, and 0.05 to 1.0% is even more preferable. This range is preferable because it provides excellent improvement in dispersibility and excellent moderate settling.

The method of treating component (A) used in the present invention can utilize known surface coating treatment methods that have been used to modify powders used in compositions and cosmetics. For example, a wet method using a solvent or a dry method in which the powder is treated in the gas phase can be used. In particular, it is preferable to disperse the mixture or dry it to pulverize it after mixing. The equipment is not particularly limited, but rotary mixers such as super mixers, Henschel mixers, ultra mixers, and kneaders, dry grinding equipment such as jetizers, atomizers, and grinders that grind in a dry state, and dry media mills can be used. In particular, the use of dry media mills is preferable because they can apply shear and improve the dispersibility of component (a1). A dry media mill refers to equipment that can grind powdered bulk by stirring it with a grinding medium, and specific examples include ball mills (made by Makino Co., Ltd.), planetary ball mills (made by Fritsch Co., Ltd.), attritors (made by Nippon Coke & Engineering Co., Ltd.), dry star (made by Ashizawa Finetech Co., Ltd.), and converge mills (made by Makabe Giken Co., Ltd.), and one or more of these can be used. In particular, the method of grinding using a planetary ball mill is preferred because it produces less aggregation, has uniform adhesion, and is excellent at covering irregularities. The processing time and force are adjusted according to the characteristics of the equipment, and it is preferable not to change the shape of component (a2) to within the spherical range.

The component (A) used in the present invention is preferably obtained by surface-coating the component (a2) with the component (a1) and a volatile oil, and then evaporating the volatile oil. The volatile oil used in the production of this component (A) is used as an unprescribed component, and is ultimately not substantially contained in the surface-coated powder (A), or even if it is contained in a small amount, it is less than 0.1%. Volatile oil refers to an oil that is volatile at room temperature, and oils such as hydrocarbon oils such as isoparaffin and silicone oils having a low boiling point (boiling point at normal pressure of 260°C or less) are preferably used. Examples of hydrocarbon oils such as low-boiling point isoparaffin (light isoparaffins) include isododecane and isohexadecane. Commercially available products include Isopar A, Isopar C, Isopar E, Isopar G, Isopar H, Isopar K, Isopar L, and Isopar M (all manufactured by Exxon Chemical), Shellsol 71 (manufactured by Shell), Soltrol 100, Soltrol 130, and Soltrol 220 (all manufactured by Philips Chemical), ISODODECANE (INEOS OLIGOMERS), etc. Volatile silicone oils include cyclomethicone and low-boiling dimethylpolysiloxane. Specifically, examples of cyclomethicone include hexamethylcyclotrisiloxane, octamethyltetracyclosiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, and tetradecamethylcycloheptasiloxane. Commercially available products include, for example, octamethyltetracyclosiloxane, Execole D-4 (manufactured by Shin-Etsu Chemical Co., Ltd.), SH244, and SH344 (all manufactured by Toray Dow Corning Co., Ltd.), decamethylcyclopentasiloxane, Execole D-5 (manufactured by Shin-Etsu Chemical Co., Ltd.), SH245, and DC345 (all manufactured by Toray Dow Corning Co., Ltd.), and dodecamethylcyclohexasiloxane, DC246 (manufactured by Toray Dow Corning Co., Ltd.), etc. Examples of low-boiling dimethylpolysiloxanes include KF-96L-2CS, KF-96L-1.5CS, and branched TMF-1.5 (manufactured by Shin-Etsu Chemical Co., Ltd.). Alcohol solvents such as ethanol and isopropanol may also be used. In particular, when water is used in combination as a dispersion medium, there is a high possibility of aggregation, so low-boiling hydrocarbon oils, low-boiling dimethylpolysiloxanes, and alcohols that reduce polarity are preferably used. One or more types may be used in combination as necessary. The volatile oil used to treat component (A) is not particularly limited, but it is preferable to use one that swells (a1) in order to increase the dispersibility of (a1) during treatment and to increase the uniformity of the surface treatment.

The volatile oil used in the component (A) used in the present invention may be used temporarily to give fluidity to (a1) and achieve uniform processing. The content is not particularly limited, but the fluidity of these components (A) during processing is set according to the oil absorption and specific surface area of the powder. Among them, dry processing is preferable. Dry processing means that the mixture does not form a continuous clay-like layer during the manufacturing process (mixing). This region is more preferable in terms of cost, time, elimination of load on the equipment during processing, and easier realization of uniform coating. The total content mass of component (a1), optionally (a3) and (a4), and non-prescribed components (such as volatile oil agents) is preferably approximately 1 to 40% per 100 parts by mass of component (a2), as appropriately adjusted according to the specific surface area and oil absorption of the powder, but is not particularly limited. Dry processing is easy in the region where the oil absorption is not reached, that is, when the mixed state including components (a1), (a2), (a3), (a4), and non-prescribed components does not form a continuous layer. It is preferable to adjust the content of these non-formulated components while considering both the uniformity of components (a1) to (a4) and the processing efficiency, as this ultimately leads to a uniform coating and a shortened drying processing time. Specifically, the content of the volatile oil during processing is preferably 1 to 30%, and more preferably 5 to 20%, when component (A) is taken as 100%, but is not particularly limited and may be adjusted appropriately depending on component (a2).

The content of component (A) in the oil-based composition of the present invention is not particularly limited. The lower limit is preferably 0.05% or more, more preferably 0.1% or more, and even more preferably 1% or more. The upper limit is preferably 60% or less, more preferably 40% or less, and even more preferably 30% or less. Also, 0.05 to 60% is preferable, more preferably 0.1 to 40%, and even more preferably 1.0 to 30%. This range is preferable because component (A) improves the dispersibility of component (B) in component (C) and provides an excellent soft feel.

The effect of component (A) as a powder dispersant in the present invention will be described. The factor by which the effect of improving the dispersibility of the colored powder of component (B) is obtained is not particularly limited, but is hypothetically considered as follows. As component (A), component (a1) is uniformly coated on the powder surface of component (a2), and a uniform component (a1) layer is stably dispersed and maintained over time in the oil-based composition containing component (C), and the component (a1) layer adsorbs component (B), which is prone to agglomeration, and component (B) is automatically dispersed as component (B) is adsorbed to the uniform (a1) layer, and it is considered that component (B) has the effect of stably improving and maintaining dispersibility. In other words, uniform dispersion of component (a1) is important, and it is also considered that component (a2) supports component (a1) on its surface and is less likely to aggregate in a spherical shape of a certain size, making it easier to maintain dispersion for a long time. Even if component (a1) alone is temporarily dispersed in the water phase or oil phase of an oil-based composition by applying pressure or using a surfactant, etc., it is likely to re-aggregate when left to stand for a long period of time, so it is unlikely that the effect of improving dispersibility can be obtained. Based on the above considerations, it is believed that component (A) has the effect of acting as a powder dispersant.

<Component (B)>
The colored powder having an average particle size of 0.01 to 1.0 μm as component (B) used in the present invention is a powder having a coloring effect on skin, hair, etc., and is not particularly limited in coloring effect. Furthermore, the aspect ratio, refractive index, and material are not particularly limited, but are other than the conditions of component (a2). For example, metal oxides such as aluminum oxide, silicic anhydride, magnesium oxide, chromium oxide, chromium hydroxide, titanium oxide, black titanium oxide, cerium oxide, red iron oxide, yellow iron oxide, black iron oxide, and zinc oxide; colored pigments such as carbon black, konjou, and ultramarine; extender powders such as magnesium carbonate, calcium carbonate, calcium sulfate, aluminum silicate, magnesium silicate, aluminum magnesium silicate, mica, synthetic mica, sericite, talc, kaolin, silicon carbide, barium sulfate, and boron nitride; organic pigment powders such as Red No. 201, Red No. 202, Red No. 205, Red No. 226, Red No. 228, Orange No. 203, Orange No. 204, Blue No. 404, and 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, and Green No. 201; No. 204, No. 205, No. 401, No. 402, No. 4, No. 5, No. 202 (1), No. 202 (2), No. 203, No. 402, No. 403 (1), No. 406, No. 407, No. 205, No. 205, No. 402, No. 403 (1), No. 406, No. 407, No. 205, No. 402, No. 2, No. 3, No. 102, No. 104 (1), No. 105 (1), No. 106, No. 227, No. 230 (1), No. 231, No. 401, No. 502, No. 503, No. 504, No. 506, and the like. More preferred are color pigments such as metal oxides, carbon black, konjou, and ultramarine, and tar dyes, and in particular, one or more selected from titanium oxide, zinc oxide, iron oxide, konjou, and tar dyes are more preferably used. Within this range, the effect of improving dispersibility can be easily exhibited, which is preferable.

The component (B) used in the oil-based composition of the present invention may be surface-coated with a surface treatment agent. Specifically, the inorganic coating is preferably further coated with one or more oxides or hydroxides selected from silicon, aluminum, and iron.
As the organic coating, a silicone compound, silane treatment, metal soap, collagen, hydrocarbon, higher fatty acid, lecithin, higher alcohol, ester, wax, amino acid, surfactant, etc. may be used to apply a surface coating by a known method, or a composite of these may be used. Here, the metal soap of the surface treatment agent in the present invention is a product neutralized with a fatty acid and a base, and examples thereof include zinc stearate, magnesium stearate, zinc myristate, zinc laurate, etc. In addition, the amino acid of the surface treatment agent in the present invention includes not only amino acids such as theanine, but also salts of amino acids and derivatives thereof. For example, N-acylated amino acids or salts thereof may be mentioned, and specific examples thereof include disodium stearoyl glutamate, sodium dilauroyl glutamate lysine, etc. In addition, the silicone compound of the surface treatment agent in the present invention may be methyl polysiloxane, hydrogen polysiloxane, etc. In addition, the silane treatment of the surface treatment agent in the present invention may be, for example, triethoxycaprylyl silane, aminopropyl triethoxy silane, etc. By carrying out these surface treatments, it is expected that the dispersibility of component (B) in component (C) will be further improved. However, in the present invention, it is noteworthy that the dispersibility of the oil-based composition can be improved by the effect of component (A) as a powder dispersant even without carrying out organic treatment, and it is particularly noteworthy that the dispersibility is improved by component (A) even without dispersing component (B) under high pressure in advance.

The content of component (B) in the oil-based composition of the present invention is preferably 0.1% or more as a lower limit, more preferably 1.0% or more, and even more preferably 1.5% or more. The upper limit is preferably 50% or less, more preferably 40% or less, even more preferably 30% or less, and even more preferably 20% or less. Also, 0.1 to 50% is preferable, 1.0 to 40% is more preferable, 1 to 30% is more preferable, and 1.5 to 20% is even more preferable. This range is preferable because it improves dispersibility while providing an excellent moderate fit.

The mass ratio of component (B) to component (A) in the oil-based composition of the present invention, (B)/(A), is 0.1 to 20. It is more preferable that (B)/(A) is 0.2 to 20. If it is smaller than this range, the effect of improving dispersibility is naturally high, but it is difficult to obtain a soft feel, and if it is larger than this range, the improvement in dispersibility is insufficient, and although the effect of improving the dispersibility of component (A) itself is not reduced, it is not preferable in terms of appropriate settling. This is preferable because it is in the range where component (A) can fully exert its function as a powder dispersant.

<Component (C)>
The component (C) used in the present invention is not particularly limited as long as it is an oil that is liquid at 25° C. For example, oils that are generally used in cosmetics, such as hydrocarbon oils, ester oils, higher alcohols, silicone oils, fluorine-based oils, and fatty acids, can be used, regardless of their origin (such as animal oils, vegetable oils, and synthetic oils) and their characteristics (such as volatile oils and non-volatile oils).

Examples of the fatty acid include oleic acid, coconut oil fatty acid, isostearic acid, linoleic acid, and linolenic acid. One or more of these may be used. In particular, hydrocarbon oils, ester oils, higher alcohols, and silicone oils are preferred. These oils are preferred because they allow component (A) to more easily function as a powder dispersant. In particular, they can maintain the effect of improving dispersibility.

The content of component (C) in the oil-based composition of the present invention is not particularly limited, but the lower limit is preferably 5% or more, more preferably 10% or more, more preferably 20% or more, even more preferably 25% or more, and even more preferably 30% or more. The upper limit is preferably 90% or less, more preferably 87% or less, and even more preferably 85% or less. Also, 5 to 90% is preferable, more preferably 15 to 87%, and even more preferably 30 to 85%. This range is preferable because it brings about an effect of improving dispersibility and has an excellent moderate settling effect.

The oil-based composition of the present invention further contains, as component (D) surfactant, one or more selected from polyhydroxystearic acid, (acrylates/ethylhexyl acrylate/dimethicone methacrylate) copolymer, alkyl-modified polyether-modified silicone, polyglycerin fatty acid ester, glycerin fatty acid ester, and sorbitan fatty acid ester. Examples of commercially available products of component (D) include KP-578 (manufactured by Shin-Etsu Chemical Co., Ltd.), KF-6038 (manufactured by Shin-Etsu Chemical Co., Ltd.), NIKKOL HEXAGLYN PR-15 (manufactured by Nikko Chemicals Co., Ltd.), and Cosmol 182V (manufactured by Nisshin Oillio Co., Ltd.).

The content of component (D) in the oil-based composition of the present invention is preferably 0.1% or more as a lower limit, more preferably 0.3% or more, and even more preferably 0.5% or more. The content is preferably 10% or less as an upper limit, more preferably 8% or less, and even more preferably 6% or less. Also, the content is preferably 0.1 to 10%, more preferably 0.3 to 8%, and even more preferably 0.5 to 6%.
The content of component (D) in the cosmetic of the present invention is preferably 0.1% or more as a lower limit, more preferably 0.3% or more, and even more preferably 0.5% or more. The upper limit is preferably 10% or less, more preferably 8% or less, and even more preferably 6% or less. Also, it is preferably 0.1 to 10%, more preferably 0.3 to 8%, and even more preferably 0.5 to 6%. Within these ranges, the improvement of dispersibility and the appropriate fit are excellent, but there are no particular limitations.

In the oil-based composition of the present invention, a (meth)acrylic acid-based film-forming agent and a silicone-based film-forming agent can be further used as the component (E) film-forming agent. Any of those used in ordinary cosmetics can be used. Specifically, the (meth)acrylic acid-based film-forming agent includes acrylic acid/alkyl copolymer and alkyl acrylate/styrene copolymer, and the silicone-based film-forming agent includes trimethylsiloxysilicate, trifluoroalkyldimethyltrimethylsiloxysilicate, polymethylsilsesquioxane, (acrylates/dimethicone) copolymer, (acrylates/stearyl acrylate/dimethicone methacrylate) copolymer, (acrylates/behenyl acrylate/dimethicone methacrylate) copolymer, dimethiconol, etc. One or more of these can be used.

The content of component (E) in the oil-based composition of the present invention is preferably 0.5% or more as a lower limit, more preferably 1.0% or more, and even more preferably 2% or more. The content is preferably 15% or less as an upper limit, more preferably 10% or less, and even more preferably 7% or less. Also, it is preferably 0.5 to 15%, more preferably 1.0 to 10%, and even more preferably 2 to 7%.

The oily composition of the present invention is not particularly limited in its use. Examples include paints, dyes, printing inks, paints, cosmetics, and skin external preparations. It is preferably used as a cosmetic or skin external preparation, and more preferably used as a cosmetic. The cosmetic may be a cosmetic containing the oily composition, or the oily composition itself may be a cosmetic, and the scope of the cosmetic is not particularly limited.
The method of producing the oily composition of the present invention is not particularly limited, and it can be prepared by mixing the above-mentioned components.The mixing method is also not limited, and it can be adopted as long as it is a normal method that can disperse uniformly.For example, a roller mill, a bead mill, a jet mill, a high-pressure homogenizer, and other dispersing machines and devices can be used, but the liquid dispersion of the present invention can be easily prepared even with a simple agitator, such as a disperser, a high rotor, a paddle mixer, a propeller mixer, and other simple dispersing machines without using these high-pressure dispersing machines and devices, so adding component (A) has the advantage that a high-pressure dispersing machine is not necessary, or it can be used to compensate for poor dispersion.

The properties of the oily composition of the present invention are not particularly limited, and may be liquid, emulsion, powder, solid, etc. For example, the oily composition may be prepared by mixing and dispersing the above components (A), (B), and (C) with components (D), (E), or other components contained as necessary.

Cosmetics using the oil-based composition of the present invention can contain ingredients such as oils, aqueous ingredients, powders (pigments, dyes, and body powders), fluorine compounds, resins, surfactants, thickeners, waxes, preservatives, fragrances, UV shielding agents (including organic and inorganic types, and may be compatible with either UV-A or UV-B), moisturizers, salts, solvents, antioxidants, chelating agents, neutralizing agents, pH adjusters, and beauty ingredients (skin whitening agents, cell activators, anti-inflammatory agents, blood circulation promoters, skin astringents, antiseborrheic agents, etc.) that are normally used in cosmetics. In particular, it is preferable that the spherical powder other than component (A) is not microplastic beads, and it is more preferable that the oil-based composition and cosmetics do not contain microplastic beads.

The optimal form of the cosmetic using the oily composition of the present invention may include powder, liquid, emulsion, aerosol-filled cosmetic, solid form obtained by melt-filling, powder solid, etc. In particular, the formulation form is preferably one that passes through a liquid state during production, and one or more types selected from water-in-oil emulsion cosmetic, oil-in-water emulsion cosmetic, and oil-based cosmetic are particularly preferred. Among these, water-in-oil emulsion cosmetic and oil-based cosmetic are preferred in that they are more likely to exert their effects.
When the cosmetic is made into a solid form, examples of the method include a method in which the cosmetic is filled and molded into a metal or resin container (melt-filling molding), and a method in which the cosmetic is dispersed in a solvent in advance and then filled, followed by removing the solvent or drying and molding (wet-filling molding).

The cosmetic of the present invention is not particularly limited as long as it is applied to the skin or hair, but examples include makeup cosmetics such as lotion, milky lotion, sunscreen, foundation, concealer, face powder, eye shadow, eyebrow, eyeliner, blusher, and lipstick, and hair cosmetics such as hair colorants. In particular, makeup cosmetics and sunscreen cosmetics are more preferred.

(Evaluation method: Improvement in dispersibility 1)
Each of the above-mentioned Examples 1 to 32 and Comparative Examples 1 to 8 was mixed with 1 part of light isoparaffin*24, placed in a container and shaken 20 times, after which one drop was dropped onto a glass plate, sandwiched between slides and observed under an optical microscope. "Improvement of dispersibility 1" was evaluated on a 5-point scale according to the following evaluation criteria, and a score was assigned to each sample, and the average score was judged according to the following evaluation criteria.

Evaluation Criteria "Improvement of Dispersibility" 1:
[Evaluation result]: [Score]
No aggregation of component (B) is observed, or if any, the size is 5 μm or less.
5 points: The aggregate size of component (B) is more than 5 μm and 20 μm or less.
4 points: The aggregates of component (B) are more than 20 μm and up to 50 μm.
3 points: One aggregate of component (B) can be visually confirmed. 2 points: Two or more aggregates of component (B) can be visually confirmed. 1 point

(Evaluation method: Improvement in dispersibility 2)
The subjects were asked to apply 0.5 g of each of the above-mentioned Examples 1 to 32 and Comparative Examples 1 to 8 onto the skin with their fingers, and the "improvement in dispersibility 2" during application was evaluated. The improvement in dispersibility is evaluated as being good when there is no aggregation of component (B) upon application to the skin, there is little difference between the sample appearance and the applied color, or there is little color change upon application. Five cosmetic product expert evaluators evaluated the "improvement in dispersibility" on a 5-point scale according to the following evaluation criteria, assigning a score to each sample, and further the average score of the scores of all cosmetic product expert evaluators was judged according to the following judgment criteria.

Evaluation Criteria: "Improved Dispersibility" 2
[Evaluation result]: [Score]
Very good: 5 points Fairly good: 4 points Neither good nor bad: 3 points Fairly bad: 2 points Very bad: 1 point

Criteria: "Improved Dispersibility" (Comprehensive evaluation of 1 and 2)
[Average score]: [Judgment]
4.5 or higher: AA
4.0 or more and less than 4.5: A
3.5 or more and less than 4.0: B
2.0 or more and less than 3.5: C
1.0 or more and less than 2.0: D

As shown in FIG. 2, when a drop of the cosmetic was placed on a glass plate and sandwiched between slides and observed visually, aggregates were also observed in the samples that showed a color change, as in Comparative Examples 4 and 5.

(Evaluation method: soft feel)
The "soft feel" of the cosmetic samples of Examples 1 to 32 and Comparative Examples 1 to 8 was evaluated according to the following procedure. Five cosmetic expert evaluators applied 0.5 g of each of the samples of the Examples and Comparative Examples shown in Tables 5 to 8 to the skin with their fingers, and evaluated the "soft feel" during application. Each expert evaluator gave a score for each sample on a 5-point scale according to the following evaluation criteria, and the average score of all the expert cosmetic evaluators' scores was then judged according to the following judgment criteria.

Evaluation criteria: "Soft feel"
[Evaluation result]: [Score]
Very good: 5 points Fairly good: 4 points Neither good nor bad: 3 points Fairly bad: 2 points Very bad: 1 point

Judgment criteria: "Soft feel"
[Average score]: [Judgment]
4.5 or higher: AA
4.0 or more and less than 4.5: A
3.5 or more and less than 4.0: B
2.0 or more and less than 3.5: C
1.0 or more and less than 2.0: D

(Evaluation method: moderate fit)
The subjects were asked to apply 0.5 g of each of the samples of Cosmetic Examples 1 to 32 and Cosmetic Comparative Examples 1 to 8 onto the skin with their fingers, and the "adequate settling" during application was evaluated. Adequate settling refers to a well-balanced spread that does not cause a heavy, tight feeling during application just before the coating film is formed, and does not cause a sticky feeling after the coating film becomes uniform. Five cosmetic expert evaluators each gave a score on a 5-point scale according to the following evaluation criteria, and then the average score of all the cosmetic expert evaluators' scores was judged according to the following judgment criteria.
Judgment criteria for "moderate fit":
[Average score]: [Judgment]
Very good: 5 points Fairly good: 4 points Neither good nor bad: 3 points Fairly bad: 2 points Very bad: 1 point

Judgment criteria: "Moderate fit"
[Average score]: [Judgment]
4.5 or higher: AA
4.0 or more and less than 4.5: A
3.5 or more and less than 4.0: B
2.0 or more and less than 3.5: C
1.0 or more and less than 2.0: D

The water-in-oil emulsion cosmetics (BB cream (liquid foundation, sunscreen, base cosmetic)) of Examples 1 to 32 had excellent dispersibility, while also providing a soft feel and appropriate fit. This is presumably due to the fact that component (A) was uniformly present throughout the liquid foundation. Example 13-2, which differed in process, demonstrated that the effect of improving dispersibility could be seen even without dispersing component (B) under high pressure using a roller mill or the like, and the powder dispersant effect of component (A) was confirmed regardless of whether component (B) was dispersed in advance or not.
On the other hand, in Comparative Example 1 of the cosmetic composition, in which only the component (a2) porous silica was blended without the component (a1) instead of the component A, the improvement of dispersibility, the soft feel, and the appropriate settling were not favorable.
In the comparative cosmetic example 2 in which component (a2) nonporous silica was blended in place of component A, the improvement in dispersibility, soft feel, and appropriate set were not favorable.
In Comparative Example 3, in which a crosslinked silicone/network silicone block copolymer was blended only as component (a1) instead of component A, the improvement in dispersibility and appropriate settling were not satisfactory.
In the case of Comparative Example 4, in which porous silica was blended with crosslinked methylpolysiloxane without surface treatment instead of Component A, the improvement in dispersibility was not favorable.
In Comparative Example 5, which was produced by blending porous silica with crosslinked methylpolysiloxane without surface treatment instead of component A and using the high rotor process, the improvement in dispersibility, soft feel, and appropriate set were not favorable.
In the cosmetic preparation of Comparative Example 6, which contained the powder of Comparative Production Example 1 in which talc was surface-treated with crosslinked methylpolysiloxane instead of component A, the improvement in dispersibility and the soft feel were not favorable.
The same evaluation was obtained for a cosmetic composition containing, instead of component A, powder produced by surface-treating synthetic fluorophlogopite with crosslinked methylpolysiloxane (Production Comparative Example 2).
In the cosmetic preparation of Comparative Example 7, in which zinc oxide having a large particle size was blended instead of component (B), the soft feel and appropriate fit were not favorable.
In the comparative cosmetic example 8, which does not contain the component (B), the results showed that the appropriate set was not favorable.
