Description

[Technical Field]

[0001] The present invention relates to an oil-based solid cosmetic composition having multiple functions in a single composition, more specifically, an oil-based solid cosmetic composition that, when applied thickly, provides excellent soft focus, uniformity of the applied film, adhesion, and makeup retention, while, when applied thinly and spreadably, provides excellent gloss, long-lasting gloss, uniformity of the applied film, adhesion, and spreadability, thereby achieving different makeup effects by changing the method of use. [Background technology]

[0002] In recent years, with the rise of women in the workplace, there has been an increasing demand for time-saving and multi-functional makeup products (2-in-1, etc.). As makeup often involves combining multiple makeup products (eye shadow, eye liner, mascara, lipstick, blush, makeup base, foundation, highlighter, concealer, etc.), there is a growing need for products that allow for quick makeup application on busy mornings and for added value.

[0003] Concealers are makeup cosmetics that make imperfections due to skin morphology, such as age spots, freckles, skin discoloration such as dark circles and dullness, and skin irregularities such as pores and wrinkles, less noticeable. Conventional concealers require high coverage to make uneven skin tone and irregularities less noticeable, and contain large amounts of white opaque pigments such as titanium oxide. However, while these concealers do indeed make skin imperfections less noticeable, they have the problem that "the coverage is too high, which increases the surface reflection of the makeup product itself, eliminating the translucency and three-dimensionality that the skin naturally has, resulting in a flat, unnatural finish."

[0004] For example, in order to correct skin imperfections with a natural finish, a product has been investigated that uses (a) a compound in which carboxyl groups at both ends of an oligomer ester of dimer acid and dimer diol are esterified with isostearyl alcohol, and (b) a soft focus effect using spherical powder with a refractive index of 1.35 to 1.5 to correct skin morphology such as pores and wrinkles without looking unnatural (Patent Document 1). The soft focus effect is the effect of scattering reflected light from the powder in multiple directions, making it difficult to see what is underneath the powder. This effect allows for the correction of skin imperfections such as wrinkles, age spots, freckles, and uneven skin tone with a natural finish. To effectively achieve soft focus, it is effective to utilize light scattering within the composition, which usually requires the composition itself to have a certain degree of transparency.

[0005] Highlighters are also a type of makeup cosmetic that brightens the skin. Conventional highlighters, when formulated with large amounts of white opaque pigments such as titanium oxide to achieve a brighter skin tone, end up with a matte finish that is difficult to maintain. For this reason, products that achieve a glossy finish by using pearlescent pigments, which are mica coated with titanium oxide, are the mainstream. However, pearlescent pigments have the disadvantage of making wrinkles more noticeable because they mainly have a specular reflection.

[0006] Patent Document 2 discloses a cosmetic composition that contains a silicone elastomer coating of a flaky substrate powder and a volatile silicone oil, and that reduces the appearance of pores while providing an excellent glossy finish. Patent Document 3 also discloses a cosmetic composition that contains starch and a polymer derived from acryloylethyl tri(C1-C3 alkyl)ammonium salt, and that provides a soft focus and radiant effect to the skin. However, both of these compositions have the drawback of producing an unnatural glossy finish upon application, and failing to create a three-dimensional look on the face when used as a "highlighter."

[0007] Furthermore, Patent Document 4 discloses a cosmetic composition containing spherical silicone particles and polyorganosiloxane, and Patent Document 5 discloses an oily solid cosmetic composition containing a polyurethane gel composition, an oily gelling agent, and spherical powder. While both of these compositions produce a uniform cosmetic film with excellent spreadability, soft focus effect, and makeup durability, there is no mention whatsoever of a glossy finish (highlighting effect).

[0008] Patent Document 6 discloses a stick-type oily solid cosmetic containing a composite powder in which a core made of a polymer component other than solid wax and polyurethane is coated with polyurethane. While the cosmetic has a good matte effect and a good feel in use (spreadability and texture), and is stable over time, this document makes no mention of a glossy feel.

[0009] Patent Document 7 discloses an oil-based solid cosmetic preparation containing an oil that is liquid at 25° C., an oil that is solid or semi-solid at 25° C., and powder that maintains a specific particle size. While the preparation is easy to apply evenly, allows for a large amount of adhesion, and is excellent in immediately making uneven skin tone such as blemishes less visible, this document also makes no mention of a glossy feel.

[0010] For the above reasons, particularly from an optical standpoint, it has been extremely difficult to achieve two contradictory effects at the same time, since soft focus is the diffuse reflection of light and gloss is the regular reflection of light.

[0011] The inventors investigated whether it would be possible to create a composition that would have different makeup effects by changing the method of use, and that would function as a concealer with a soft focus effect and also as a highlighter with a high level of shine, even when a large amount of white opaque pigment is blended, thereby achieving multiple unprecedented makeup effects.

[0013] The present invention has been made in view of the above-mentioned prior art, and an object of the present invention is to provide an oil-based solid cosmetic composition that has multiple functions in a single composition, specifically an oil-based solid cosmetic composition that, when applied thickly, provides excellent soft focus properties, uniformity of the applied film, adhesion, and cosmetic longevity, while, when applied thinly and spreadably, provides high gloss, long-lasting gloss, uniformity of the applied film, adhesion, and spreadability, thereby achieving different makeup effects by changing the method of use. [Means for solving the problem]

[0014] In order to achieve the above object, the present inventors conducted extensive research and discovered that an oily solid cosmetic composition that achieves the above object can be obtained by blending components (A) to (E), thereby completing the present invention.

[0015] The first invention is (A) 3 to 15% by mass of microcrystalline wax (B) 2 to 15% by mass of one or more spherical powders selected from alkyl polyacrylate powders and polyurethane powders (C) One or more oils with a viscosity of 5 to 50 mPa·s at 20°C (D) 15 to 35 mass% of one or more metal oxides selected from titanium oxide and zinc oxide (E) 2 to 10% by mass of one or more selected from pentaerythritol fatty acid esters and dipentaerythritol fatty acid esters The oily solid cosmetic composition comprises:

The oily solid cosmetic composition according to any one of claims 1 to 3, characterized in that it has a high glossy feel when 0.002 g of the oily solid cosmetic composition is uniformly applied to the skin. [Effects of the Invention]

[0019] The oily solid cosmetic composition of the present invention, when applied thickly, is excellent in soft focus properties, uniformity of the applied film, adhesion, and cosmetic longevity, while when applied thinly and spreadably, is excellent in glossiness, long-lasting glossiness, uniformity of the applied film, adhesion, and spreadability, and different makeup effects can be obtained by changing the method of use. BEST MODE FOR CARRYING OUT THE INVENTION

[0020] The present invention will be described in more detail below. Unless otherwise noted, when the amount of a component is expressed as "%", it means % by mass. The following amount of a component indicates the pure content of the component.

[0021] The term "oily solid cosmetic composition" as used herein refers to an oily cosmetic composition that exhibits solid properties at 25°C. The oily solid cosmetic composition of the present invention is not particularly limited in its formulation, as long as it is solid at 25°C. For example, the composition can be molded by heating and dissolving it, pouring it into a mold, and cooling it, and examples of formulations include sticks and container-filled products. Furthermore, in the present invention, "oily" refers to a composition in which oil is the continuous phase and which contains substantially no water, or if it contains water, it contains 1% by mass or less.

[0022] The oil-based solid cosmetic composition of the present invention, by incorporating a high amount of microcrystalline wax, achieves a high soft-focus effect when applied thickly. Unlike crystalline waxes such as paraffin wax and high-density polyethylene wax, microcrystalline wax is largely composed of a branched structure, resulting in high transparency and easy light transmission. Therefore, despite incorporating a high amount of titanium oxide or zinc oxide, which have high hiding power, the composition of the present invention is able to blur skin irregularities, blemishes, and wrinkles while allowing the skin to show through without causing specular reflection. In other words, by incorporating a high amount of microcrystalline wax into a large amount of powder with high hiding power, it is possible to achieve an enhanced soft-focus effect with a natural finish, rather than unnatural covering power. On the other hand, when applied thinly, the microcrystalline wax maintains a uniform wax structure, forming a uniform coating film with the glossy feel inherent in liquid oil. Furthermore, the microcrystalline wax retains the liquid oil in its crystals to a moderate degree, reducing the liquid oil's affinity for the skin, allowing the high glossy feel to last for a long time.

[0023] The microcrystalline wax (A) used in the present invention may be any wax commonly used in cosmetics, and may be used alone or in suitable combination of two or more kinds.

[0024] In the present invention, microcrystalline wax refers to a wax containing a high proportion of branched structures, such as microcrystalline wax or low-density polyethylene. It is generally known that waxes with many branched or cyclic structures have low crystallinity, making them difficult to grow as crystals, and are composed of microcrystals. It is also known that they inhibit the crystal growth of other highly crystalline waxes. Furthermore, because the crystalline structure of the oil-based solid cosmetic composition is refined, it can be spread thinly while maintaining a uniform structure. The microcrystals retain the low-viscosity liquid oil, resulting in the formation of a uniformly applied film with a glossy feel. Furthermore, the microcrystals retain the low-viscosity liquid oil, reducing the low-viscosity liquid oil's affinity to the skin, resulting in a long-lasting high gloss.

[0025] In the present invention, when a microcrystalline wax is used as the microcrystalline wax (A), it preferably has a melting point of 70° C. to 85° C. Commercially available products include refined microcrystalline wax (manufactured by Nikko Rica Corporation), Multiwax W-445, W-835 (manufactured by Sonneborn LLC), and the like.

[0026] Structurally, polyethylene is a thermoplastic plastic obtained by polymerizing ethylene, and is classified into low-density polyethylene, high-density polyethylene, linear low-density polyethylene, ultra-high-molecular-weight polyethylene, etc., depending on differences in density, molecular weight, molecular weight distribution, and molecular structure (type of branching, branching degree distribution). The polyethylene used in the present invention refers to polyethylene with a high branching structure, such as low-density polyethylene and linear low-density polyethylene. Because low-density polyethylene and linear low-density polyethylene have a high branching structure, they have low crystallinity and form fine crystals. Therefore, when an oil-based solid cosmetic composition is spread thinly, they retain low-viscosity liquid oil and form a uniformly applied film with a glossy feel. Furthermore, they reduce the affinity of low-viscosity liquid oil to the skin, allowing the high glossy feel to last for a long time.

[0027] In the present invention, when polyethylene is used as the microcrystalline wax (A), for example, the melting point is 90°C to 130°C and the density is 0.900 to 0.940 g / cm3 The crystallinity is 40 to 60%.

[0028] The blending amount of component (A) is 3 to 15% by mass, more preferably 5 to 10% by mass, based on the total amount of the oil-based solid cosmetic composition. Within this range, the oil-based solid cosmetic composition is excellent in all aspects: soft focus, uniformity of the applied film, adhesion, and cosmetic longevity when applied thickly; and gloss, gloss persistence, uniformity of the applied film, adhesion, and spreadability when applied thinly. Below this range, a uniform applied film was not formed regardless of the application method, and the soft focus and adhesion were lacking when applied thickly, and cosmetic longevity was also insufficient. Furthermore, gloss, gloss persistence, and adhesion were also poor when applied thinly. This is thought to be primarily due to the coarsening of the wax structure of the composition as the blending amount of the microcrystalline wax decreases, causing the composition to disintegrate unevenly upon application, making it difficult to apply evenly. On the other hand, a blending amount exceeding 15% by mass is undesirable, as it results in poor spreadability when applied thinly, resulting in reduced usability.

[0029] The alkyl polyacrylate powder and polyurethane powder (B) used in the present invention can be used alone or in appropriate combination of two or more. While powders with different particle sizes are typically incorporated into cosmetics, they can be incorporated without any particular limitations. Among these, spherical shapes are preferred from the perspective of soft focus properties. Commercially available products can be incorporated, including alkyl polyacrylate powders such as "TEGO SP 13-1" (manufactured by Evonik Operations GmbH) and polyurethane powders such as "Daimic Beads UCN8155" (manufactured by Dainichiseika Color & Chemicals Mfg. Co., Ltd.) and "Grandpearl GU-0700P / GU-2000P" (manufactured by Aica Kogyo Co., Ltd.). Among these, (HDI / trimethylolhexyllactone) crosspolymer is particularly preferred from the perspective of soft focus properties and spreadability. (HDI / trimethylolhexyllactone) crosspolymer is a urethane resin made by powdering a polymer obtained by reacting trimethylolpropane with hexamethylene diisocyanate.

[0030] The blending amount of component (B) is 2 to 15% by mass, more preferably 7 to 12% by mass, based on the total amount of the oil-based solid cosmetic composition. Within this range, the oil-based solid cosmetic composition provides excellent soft focus when applied thickly, and excellent spreadability when spread thinly.

[0031] The oil (C) used in the present invention may be any oil commonly used in cosmetics, and may be used alone or in combination of two or more. From the viewpoints of gloss and spreadability, the viscosity of the oil is preferably 5 to 50 mPa·s at 20°C, and more preferably 5 to 30 mPa·s.

[0032] The viscosity is measured in an environment of 20°C using a rotational viscometer, specifically a B-type viscometer.

[0033] For example, hydrogenated polyisobutene, caprylic / capric triglyceride, neopentyl glycol dicaprate, isoamyl laurate, hexyl laurate, isopropyl myristate, isocetyl myristate, octyldodecyl myristate, isopropyl palmitate, ethylhexyl palmitate, isocetyl stearate, ethyl isostearate, isopropyl isostearate, isobutyl isostearate, hexyldecyl isostearate, isostearyl isostearate, bis succinate Ethoxydiglycol, diethylhexyl succinate, diisobutyl adipate, isodecyl neopentanoate, isostearyl neopentanoate, cetyl ethylhexanoate, hexyldecyl ethylhexanoate, neopentyl glycol diethylhexanoate, triethylhexanoin, ethylhexyl isononanoate, isononyl isononanoate, isodecyl isononanoate, isotridecyl isononanoate, tricyclodecanemethyl isononanoate, neopentyl glycol diisononanoate, dimethicone, and the like can be used.

[0034] The amount of component (C) to be blended is not particularly limited as long as the effects of the present invention are obtained, but it is usually used in a range of preferably 30 to 70 mass % of the total amount of the oil-based solid cosmetic composition, and more preferably 40 to 60 mass %. Within this range, the oil-based solid cosmetic composition has good moldability, glossy feel when spread thinly, and extensibility.

[0035] The titanium oxide and zinc oxide (D) used in the present invention may be those conventionally blended in makeup cosmetics such as foundations, and may be used alone or in appropriate combination of two or more. The titanium oxide and zinc oxide usually have an average particle size of about 5 nm to about 1000 nm.

[0036] The surfaces of titanium oxide and zinc oxide may be hydrophobized, and the type of hydrophobizing agent used for the hydrophobizing treatment is not limited, but examples thereof include fatty acids, higher fatty acids, higher alcohols, hydrocarbons, triglycerides, esters, silicone oils, silicone resins, fluorine compounds, etc. Specific examples of hydrophobizing agents include alkyl-modified silicones, alkyltriethoxysilanes, alkyltrimethoxysilanes, perfluoroalkyl phosphates, (alkyl acrylate / dimethyl silicone) copolymers, dextrin palmitate, triethoxysilylethyl polydimethylsiloxyethylhexyl dimethicone, monomethylpolysiloxane, dimethylpolysiloxane, polymeric silicones, sodium acryloyldimethyltaurate / methacrylamidolauric acid copolymers, etc.

[0037] The blending amount of component (D) is 15 to 35% by mass, more preferably 20 to 30% by mass, based on the total amount of the oil-based solid cosmetic composition. Within this range, the oil-based solid cosmetic composition provides excellent soft focus when applied thickly and excellent gloss when spread thinly. If the amount is less than this range, the soft focus, adhesion, and cosmetic longevity are poor when applied thickly, and adhesion is also poor when applied thinly. On the other hand, if the amount exceeds this range, the covering power is further enhanced by the large amount of titanium oxide and zinc oxide, resulting in an unnatural finish. As a result, the soft focus is lost when applied thickly and adhesion is poor. Furthermore, adhesion and spreadability are poor when applied thinly, which is undesirable.

[0038] The pentaerythritol fatty acid ester and dipentaerythritol fatty acid ester (E) used in the present invention are highly polar ester oils, and those typically used in cosmetics can be used. One type can be used alone, or two or more types can be used in appropriate combination.

[0039] For example, dipentaerythrityl tetra(hydroxystearate / isostearate), dipentaerythrityl hexa(hydroxystearate / stearic acid / rosin acid), dipentaerythrityl hexahydroxystearate, etc. can be used.

[0040] Commercially available products include "Cosmol 168M," "Cosmol 168EV," and "Cosmol 168ARV" (all manufactured by Nisshin Oillio Group), and "Technol MH" (manufactured by Yokoseki Oil Industries Co., Ltd.).

[0041] The blending amount of component (E) is 2 to 10% by mass, more preferably 3 to 6% by mass, based on the total amount of the oil-based solid cosmetic composition. Within this range, the oil-based solid cosmetic composition provides excellent soft focus when applied thickly and a glossy feel when spread thinly.

[0042] In addition to the above-mentioned essential components, the oily solid cosmetic composition of the present invention may contain commonly used aqueous and oily components, such as other powder components, non-volatile oils, alcohols, polyhydric alcohols, colorants, pH adjusters, moisturizers, thickeners, surfactants, stabilizers, colorants, preservatives, antioxidants, ultraviolet absorbers, fragrances, etc.

[0043] Examples of other powder components include inorganic powders and organic resin powders including color pigments such as red iron oxide, yellow iron oxide, black iron oxide, ultramarine, cerium oxide, talc, mica, sericite, kaolin, bentonite, clay, silicic acid, silicic anhydride, magnesium silicate, zinc stearate, fluorine-containing phlogopite, synthetic talc, barium sulfate, magnesium sulfate, calcium sulfate, boron nitride, bismuth oxychloride, alumina, zirconium oxide, magnesium oxide, chromium oxide, calamine, magnesium carbonate, and complexes thereof, white pigments, silica, cellulose, pearling agents, and extender pigments, which may be surface-treated.

[0044] The oily solid cosmetic composition of the present invention, when applied thickly, provides soft focus, uniformity of the applied film, adhesion, and makeup longevity, while when spread thinly, provides excellent gloss, long-lasting gloss, uniformity of the applied film, adhesion, and spreadability. Therefore, it can be used, for example, as a highlighter, concealer, makeup base, foundation, lipstick, etc., and is particularly suitable for use in multifunctional products (highlighter concealer) that combine the functions of both a highlighter and a concealer.

[0045] The method of using the oily solid cosmetic composition of the present invention is not particularly limited, but the method of use used in the effectiveness test is as follows: When checking the soft focus effect, the composition was applied to a 4 cm area on the skin. 2 Apply 0.03 g of the oil-based solid cosmetic composition evenly to the area of ​​10 cm of the skin (hereinafter, when the phrase "apply thick layers" is used, this method is referred to). 2 Apply 0.002 g of the oily solid cosmetic composition evenly around the area (hereinafter, when the phrase "spread a thin layer" is used, this method is referred to).

[0046] A specific example of the oil-based solid cosmetic composition of the present invention is a highlighting concealer that can achieve two different makeup effects, concealer and highlighter, by changing the method of use. In other words, despite the solid oil-based cosmetic containing a large amount of white opaque pigments, such as titanium oxide and zinc oxide, at 15 to 35%, the concealer provides sufficient soft focus even when applied thickly. Even when applied thinly, the oil-based solid cosmetic composition has a high surface gloss and does not become matte. Therefore, even without the addition of pearlescent pigments, the oil-based solid cosmetic composition provides a high makeup effect, brightening the area to which it is applied when used as a highlighter. This allows for the realization of a highly convenient composition that allows users to enjoy makeup at low cost, saves space when carrying it around for makeup touch-ups, and allows for quick makeup application with just one product on busy mornings.

[0047] Another specific example of the oil-based solid cosmetic composition of the present invention is an oil-based solid cosmetic composition that combines multiple makeup effects, such as a lipstick that makes lip wrinkles less noticeable and a lipstick that has a high gloss and gives lips a moist look, or a lipstick that makes lip wrinkles less noticeable and a cheek color that gives the face a three-dimensional look with its high gloss. [Example]

[0048] Next, the oily solid cosmetic composition of the present invention will be described in detail with reference to examples, but the present invention is not limited thereto. First, the test methods and evaluation methods used in each example will be described.

[0052] [Table 1]

[0053] [Table 2]

[0054] As is clear from the results in Tables 1 and 2, Examples 1 to 9 achieved better results in all evaluation items than the Comparative Examples. On the other hand, Comparative Example 1, which did not contain component (A), failed to achieve satisfactory quality in all aspects except spreadability when applied thickly or thinly. Furthermore, Comparative Example 2, which contained component (A) in an amount exceeding the upper limit, had an excessively strong adhesion and failed to achieve satisfactory quality in terms of smooth spreadability when applied thinly. Comparative Examples 9 to 11, which used crystalline carnauba wax, ceresin, and polyethylene wax instead of component (A), exaggerated hiding power when applied thickly, resulting in a flat, unnatural finish and poor soft focus. When applied thinly, a uniform coating was not formed, resulting in unsatisfactory quality in terms of gloss and gloss durability. Furthermore, Comparative Example 3, which did not contain component (B), did not achieve the rolling sensation on the skin characteristic of spherical powders and also failed to achieve satisfactory quality in terms of soft focus. In Comparative Example 4, in which component (B) was blended in excess of the upper limit, the spread on the skin was too good, resulting in a lack of adhesion, while the increased powder content also resulted in insufficient spreadability. In other words, satisfactory quality was not achieved in terms of adhesion when applied thickly, makeup staying power, or spreadability when spread thinly. Comparative Example 12, in which talc was used instead of component (B), lacked smooth spreadability and soft focus effect due to the amorphous powder characteristics of talc itself, resulting in unsatisfactory soft focus and spreadability. Comparative Example 5, in which component (D) was blended in less than the lower limit, lacked soft focus and the reduced powder content reduced the adhesion, resulting in unsatisfactory makeup staying power. Conversely, in Comparative Example 6, in which component (D) was blended in excess of the upper limit, the increased powder content caused the makeup to flake off when spread on the skin, resulting in unsatisfactory adhesion and smooth spreadability. Furthermore, in Comparative Example 7, which did not contain component (E), the feeling of adhesion was reduced and a uniform coating film could not be formed, and satisfactory quality was not achieved in any evaluation items other than spreadability and gloss retention.In Comparative Example 8, in which component (E) was blended in excess of the upper limit, the amount of paste-like component (E) was excessive, impairing adhesion, and unsatisfactory qualities were not obtained in terms of soft focus, adhesion, makeup wear when applied thickly, and gloss retention when spread thinly.Finally, in Comparative Example 13, in which component (C) was replaced with trimethylolpropane triethylhexanoate (viscosity: 60 mPa s), the high viscosity of the liquid oil meant that unsatisfactory qualities were not obtained in terms of gloss when spread thinly, uniformity of the applied film, and spreadability.
