Solid lip cosmetic

Abstract

Provided is a lip solid cosmetic having an excellent effect of no secondary adhesion, excellent makeup retention, and a moderate glossiness of a finished makeup. By compounding a copolymer containing a dimer acid ester, or a copolymer containing a dimer acid ester and a dimer acid ester as an oil component (adhesion oil component) that adheres to the lips, and a hydrocarbon oil that is liquid at ordinary temperatures as an oil component (bleeding oil component) that bleeds to the surface layer when applied to the lips, a lip solid cosmetic having an effect of no secondary adhesion and a fairly good glossiness of a finished makeup is obtained.

Description

[0001] Related applications

[0002] This application claims priority to Japanese Patent Application No. 2021-011974, filed on January 28, 2021, which is incorporated herein by reference. Technical Field

[0003] This invention relates to an improvement of solid lip cosmetics, particularly solid lip cosmetics that offer excellent wear resistance, long-lasting wear, and a pleasantly glossy finish without requiring secondary application. Background Technology

[0004] Traditional lip makeup products often suffer from issues with secondary adhesion when applied to surfaces that come into contact with the lips, such as cups. To address this, lip makeup products have been developed that are less prone to secondary adhesion and offer a so-called "no secondary adhesion" effect.

[0005] For example, Patent Documents 1 to 4 disclose a solid lip cosmetic that uses hydrogenated polyisobutylene that adheres closely to the lips and silicone oil that has low compatibility with the hydrogenated polyisobutylene at room temperature. Although the product is a homogeneous system, the hydrogenated polyisobutylene and silicone oil are separated by shearing during use.

[0006] For lip cosmetics that have a non-adhesive effect, hydrogenated polyisobutylene adheres tightly to the lips during application, and an organosilicone oil layer forms a film on top of the hydrogenated polyisobutylene layer. Because this organosilicone oil is colorless and transparent, it is inconspicuous even when transferred to cups or similar surfaces, thus achieving a non-adhesive effect.

[0007] However, if high-viscosity oils such as hydrogenated polyisobutylene and polyisobutylene are mixed in large quantities as described above, it will result in a heavy spread or a sticky finish during application. Therefore, Patent Document 5 discloses an oil-in-oil type lip makeup that achieves excellent results by combining a specific amount of phenyl-modified organosilicon with a high-viscosity non-volatile ester oil, dextrin fatty acid ester, and further volatile hydrocarbons that are incompatible with the phenyl-modified organosilicon at high temperatures, thus avoiding stickiness and secondary adhesion.

[0008] However, the combination in Patent Document 5 cannot form a solid lip makeup material. Because it needs to be mixed with oils that are incompatible at high temperatures, even if a solid lipstick is produced, it is uneven and brittle. If phenyl-modified silicone is used, excessive shine sometimes occurs during makeup setting, leaving a problem.

[0016] The problem that the invention aims to solve

[0017] The present invention was made in view of the problems of the prior art described above, and its object is to provide a lip solid cosmetic with excellent non-adhesion effect, excellent makeup staying power, and the ability to set makeup with a moderate gloss.

[0018] Methods for solving problems

[0019] In order to solve the above-mentioned problems, the inventors conducted in-depth research and found that by mixing copolymers containing dimerates, or copolymers containing dimerates and dimerates as oils that adhere closely to the lips (adhesive oils), and mixing hydrocarbon oils that are liquid at room temperature as oils that seep to the surface when applied to the lips (seepage oils), a solid lip makeup material with no secondary adhesion and a fairly good glossy finish is formed, thus completing the present invention.

[0020] To achieve the above objectives, the solid cosmetic material for lips involved in this invention comprises the following six points.

[0021] (1) As an essential component, it includes:

[0022] (A) as a binding oil, a copolymer containing (a1) a dimer ester, or a copolymer containing (a1) a dimer ester and (a2) a dimer ester, 15-50% by mass.

[0023] (B) 20-70% by mass of non-volatile hydrocarbon oils that are liquid at room temperature.

[0024] (C) Wax 5-15% by weight.

[0025] Furthermore, the combined mass of components (A), (B), and (C) is preferably 80-100% of the total oil phase components.

[0026] Furthermore, it is suitable to include (D) pigments.

[0027] Furthermore, component (B) is compatible with component (A) at 90°C and separates from component (A) at 25°C.

[0028] (2) In the above cosmetics, the viscosity of component (B) is less than 100 mPa·s at room temperature.

[0029] (3) Among the above cosmetics, there are one or more hydrocarbon oils selected from olefin oligomers, squalane, liquid paraffin, light isoparaffins, heavy liquid paraffin, and hydrogenated polydecene (B) that are liquid at room temperature.

[0030] The ratio of (A):(B) is 1:0.5 to 1:4.

[0031] (4) In the above cosmetics, (A) contains a copolymer of dimer esters, which is a (polyglycerol-2 isostearate / dimeric linoleic acid) copolymer.

[0032] (5) In the above cosmetics, the dimer ester (A) is dimer linoleic acid dimer linoleyl alcohol ester.

[0033] (6) In the above cosmetics, the amount of phenyl-modified organosilicon is less than 5% by mass.

[0034] The effects of the invention

[0035] The solid lip cosmetic of the present invention is made by mixing (A)(a1) a copolymer containing dimer ester, or (a1) a copolymer containing dimer ester and (a2) dimer ester, (B) a hydrocarbon oil that is liquid at room temperature, and (C) wax in a specific amount, thereby achieving the effect of no secondary adhesion, a makeup surface with a very good gloss, and good makeup staying power. Detailed Implementation

[0036] The solid lip cosmetic of the present invention is composed of (A) (a1) a copolymer containing a dimer ester, or (a1) a copolymer containing a dimer ester and (a2) a dimer ester, (B) a hydrocarbon oil that is liquid at room temperature, and (C) a wax.

[0037] The following is a detailed explanation of each component.

[0038] (A)(a1) Copolymer containing dimeric acid ester / (a2) Dimeric acid ester

[0039] (a1) The copolymer containing dimer ester is a high-viscosity, non-volatile ester oil. To improve the effect of no secondary adhesion, a substance that is compatible with (B) a hydrocarbon oil that is liquid at room temperature at 90°C and separates at 25°C is selected. Specifically, dimer linoleate copolymer can be cited as an example.

[0040] (a2) Dimer ester is an ester of liquid fatty acids containing monocarboxylic acids and tricarboxylic acids, which is mainly composed of dicarboxylic acids of C36 dicarboxylic acids generated by dimerization of C18 unsaturated fatty acids from vegetable oils.

[0041] As a commercially available product containing a dimer ester copolymer (a1), there is High-End Center ISDA (manufactured by High-End Alcohol Company).

[0042] In addition, commercially available products as (a2) dimer esters include, for example, LUSPLAN DD-DA (manufactured by Nippon Seika Co., Ltd.).

[0043] (A) The amount of ingredients mixed is suitable to be 15 to 50% by mass relative to the total amount of cosmetics.

[0044] From the viewpoint of lip adhesion and the durability of makeup effect, the preferred mixing amount is 20-40% by mass, and more preferably 25-35% by mass.

[0045] (B) Hydrocarbon oil that is liquid at room temperature

[0046] (B) Hydrocarbon oils that are liquid at room temperature need to have a viscosity of 100 mPa·s or less and be non-volatile. Any substance commonly used in cosmetics can be linear or branched; there are no particular limitations. Furthermore, in this invention, the viscosity was measured at 25°C using a spindle NO.M1 at 1000 rpm using a Type B viscometer TVB-10 (manufactured by Yamato Scientific Co., Ltd.).

[0047] Furthermore, it refers to the substance that is separated when it is mixed with (a1) a copolymer containing a dimer ester, or (a1) a copolymer containing a dimer ester and (a2) a dimer ester at 25°C.

[0048] Conditions for separation

[0049] In this invention, the presence or absence of "separation" is determined under the following conditions.

[0050] (Measurement conditions)

[0051] Component (A) and component (B) are used in a mass ratio of (A):(B) = 1:1. The mixture is heated to 90°C, stirred, and then allowed to stand. When the mixture reaches 25°C, the state in which the boundary is uniformly separated into two layers is defined as "separation," and the state in which there is no boundary and the mixture is transparent is defined as "non-separation." Furthermore, the state in which there is no visible boundary and the mixture is opaque is defined as "cloudiness."

[0052] In this invention, the presence or absence of "compatibility" is defined by the following conditions.

[0053] A state that is transparent at 90°C and whose boundaries cannot be visually confirmed, i.e., a "non-separated state," is defined as compatible.

[0054] Examples of hydrocarbon oils that are liquid at room temperature (B) include olefin oligomers, squalane, liquid paraffin, light isoparaffins, heavy liquid isoparaffins, and hydrogenated polydecene.

[0055] In addition, commercially available products that are liquid hydrocarbon oils at room temperature (B) include, for example, Nomco HP100 (manufactured by Nissin Oirio) and squalane (manufactured by Kurare).

[0056] (B) The amount of the mixed component relative to the total cosmetic product is 20-70% by mass. Preferably, it is 30-55% by mass, and more preferably, it is 35-50% by mass.

[0057] If the amount of component (B) is less than 20% by mass, it will not easily separate during application, and the effect of no secondary adhesion will not be easily achieved. In addition, if it exceeds 70% by mass, the amount of other components will decrease, and the effect of no secondary adhesion will not be easily achieved.

[0058] (B) A viscosity of 100 mPa·s or less is suitable for the component.

[0059] If the viscosity exceeds 100 mPa·s, it will be difficult to separate during application, resulting in poor makeup staying power. A further preferred viscosity is 50 mPa·s or less. Furthermore, component (B) is preferably a non-volatile oil. If it is a volatile oil, it will not function as an exudate oil, will not have a secondary adhesion effect, and will reduce makeup staying power.

[0060] A mixing ratio of 1:0.5 to 1:4 is suitable for components (A) and (B). Preferably, it is 1:0.8 to 1:3.5, and more preferably 1:1 to 1:2. Within this range, components (A) and (B) dissolve at 90°C and separate at 25°C.

[0061] (C) Wax

[0062] As for the wax (C) that is blended into the lip solid cosmetic of the present invention, there is no particular limitation as long as it is a substance that is usually blended into cosmetics.

[0063] The (C) wax used in this invention is preferably a substance that is compatible with components (A) and (B) at high temperatures and separates at room temperature.

[0064] Examples of the (C) wax used in this invention include carnauba wax, candelilla wax, polyethylene wax, beeswax, pure terrestrial wax, microcrystalline wax, solid paraffin wax, wood wax, beeswax, polyethylene wax, etc.

[0065] The amount of component (C) mixed relative to the total amount of cosmetic is preferably 5 to 15% by mass. More preferably, it is 7 to 12% by mass. If the amount of component (C) mixed is less than 5% by mass, it may be difficult to cure. If it exceeds 15% by mass, it may be difficult to spread and the gloss may be lost.

[0066] In the lip solid cosmetic of the present invention, in addition to components (A) to (C) which are the above-mentioned essential components, components commonly used in lip solid cosmetics may also be included as optional components.

[0067] In the lip solid cosmetic of the present invention, blending (D) is also suitable. As a pigment, substances commonly used in lip solid cosmetics can be blended.

[0068] As a colorant (D), it can generally be any colorant used in cosmetics, and can be in powder or lake form (in a state where oil has been added). It can be an inorganic pigment, an organic pigment, or a pearlescent agent.

[0069] At this point, it is desirable for the pigment to dissolve or disperse in component (A), which adheres tightly to the lips, but not in component (B), which acts as an exudate oil. This is because if the pigment is also dispersed in component (B), the effect of secondary adhesion will be reduced.

[0070] As (D) colorants, substances commonly mixed in cosmetics can be used, such as pigments, pearlescent agents, glitter agents, and substances that have been laked.

[0071] Examples of pigments include inorganic white pigments (titanium dioxide, zinc oxide), inorganic red pigments (iron oxide (iron oxide red), iron titanate), inorganic brown pigments (γ-iron oxide), inorganic yellow pigments (iron oxide yellow, loess), inorganic black pigments (iron oxide black, carbon, low-valent titanium dioxide), inorganic purple pigments (manganese violet, cobalt violet), inorganic green pigments (chromium oxide, chromium hydroxide, cobalt titanate), inorganic blue pigments (ultramarine, navy blue), pearlescent pigments (titanium oxide coated with mica, titanium oxide coated with bismuth oxychloride, titanium oxide coated with talc, colored titanium oxide coated with mica, bismuth oxychloride, fish scale foil), metallic powder pigments (aluminum powder, copper powder), and organic pigments (Red No. 202, red...). Organic pigments including No. 205, Red No. 220, Red No. 228, Red No. 405, Orange No. 203, Orange No. 204, Yellow No. 205, Yellow No. 40, Blue No. 404, zirconium, barium, and aluminum lake pigments (Red No. 3, Red No. 104, Red No. 227, Red No. 401, Orange No. 205, Yellow No. 4, Yellow No. 20, Green No. 3, Blue No. 1), natural pigments (chlorophyll, carotenoids (β-carotene), safflower pigment, carmine, chalcone, curcumin, betaine, flavonols, flavones, anthocyanins, anthraquinones, naphthoquinones), and functional pigments (boron nitride, photochromic pigments, synthetic fluorophlogopite, iron-containing synthetic fluorophlogopite, hybrid fine powder), etc.

[0072] The amount of component (D) mixed relative to the total amount of cosmetic is preferably 0.1 to 15% by mass, more preferably 4 to 10% by mass. If the amount of component (D) mixed is less than 0.1% by mass, the effect of no secondary adhesion may not be noticeable. Furthermore, if it exceeds 15% by mass, the amount of components (A) to (C) mixed becomes relatively small, which may reduce the effect of no secondary adhesion.

[0073] The solid lip cosmetic of the present invention can be manufactured even without a so-called "binding oil." A binding oil is a substance used to make the binding oil and the exudating oil compatible at high temperatures. The present invention may or may not include a binding oil.

[0074] Examples of binding oils include diisostearyl malate, neopentyl glycol didecanoate, triisooctanoic acid glyceride, pentaerythritol tetraethylhexanoate, and tri(octanoic acid / capric acid) glyceride. The suitable mixing amount is 0–20% by weight relative to the total cosmetic product.

[0075] In the lip solid cosmetic of the present invention, in addition to the above-mentioned components, other commonly used oils, powders, polymers, moisturizers, fragrances, antioxidants, preservatives, and cosmetic ingredients may be appropriately blended within a range that does not impair the effects of the present invention. In the present invention, when phenyl-modified organosilicon is blended, the amount is preferably less than 5% by mass of the total cosmetic. This is because if the amount of phenyl-modified organosilicon exceeds 5% by mass, the overall compatibility and stability of the oil components deteriorate.

[0076] In this invention, the amount of powder added is preferably 30% by mass or less relative to the cosmetic material. More preferably, it is 20% by mass or less. If the amount of powder added exceeds 30% by mass, the amount of components (A) to (C) mixed becomes relatively small, which may sometimes reduce the effect of preventing secondary adhesion.

[0077] Examples of powders include spherical powders and plate-shaped powders.

[0078] Examples of spherical powders include polymethyl methacrylate, organopolysiloxane elastomers, polystyrene, polyamide resins (nylon), polyethylene, copolymers of styrene and acrylic acid, benzoguanamine resins, polytetrafluoroethylene, and silicone resins.

[0079] Examples of plate-shaped powders include inorganic powders such as mica, synthetic mica, talc, sericite, alumina, magnesium oxide, zirconium oxide, magnesium carbonate, calcium carbonate, calcium sulfate, chromium oxide, chromium hydroxide, aluminum silicate, magnesium silicate, magnesium aluminum silicate, kaolin, silicon carbide, barium sulfate, bentonite, montmorillonite, and boron nitride; organic powders such as N-acyl lysine; and composite powders such as micronized titanium oxide coated with mica titanium, micronized zinc oxide coated with mica titanium, and barium sulfate coated with mica titanium.

[0080] Powders used as pigments, pearlescent agents, glitter agents, etc., can be hydrophilically treated powders. Substances known in the art that have undergone hydrophilic treatment can be used as hydrophilic treatment powders. Both organic and inorganic treatments can be performed for hydrophilic treatment. There are no particular limitations on the hydrophilic treatment agent; examples include polyols, polysaccharides, water-soluble polymers, metal alkoxides, and water glass.

[0081] The lip solid cosmetic of the present invention preferably does not separate during all its manufacturing processes and has a uniform single-phase composition.

[0082] The solid lip cosmetic of the present invention can be applied to lipsticks, lip glosses, lip bases, lip coatings, lipsticks, etc. It is particularly preferred to use a stick-shaped solid lipstick.

[0083] Example

[0084] The following examples further illustrate the invention, but the invention is not limited thereto. Unless otherwise specified, the mixing amount is expressed as a percentage by mass.

[0085] First, the inventors confirmed the compatibility of (a1) the copolymer containing dimer ester (high-temperature ISDA) with various oils. The results are shown in Table 1.

[0086] (Determination conditions for mixed states)

[0087] Component (A) and component (B) were used in a mass ratio of (A):(B) = 1:1, heated to 90°C, stirred, and their state was confirmed. The mixture was then allowed to stand, and its state was confirmed again when the temperature dropped to 25°C. A state where the boundary was uniformly separated into two layers was defined as "separation," and a state where there was no boundary and the mixture was transparent was defined as "compatibility." Furthermore, a state where there was no visible boundary and the mixture was opaque was defined as "cloudiness."

[0094] As shown in Table 1, hydrocarbon oils that are liquid at room temperature are an example of oils that are compatible at 90°C and separate at 25°C when mixed with (a1) a copolymer containing a dimer ester (HILU-SENTO ISDA).

[0095] Next, the compatibility of various (a1) copolymers containing dimer esters and / or (a2) dimer esters with various hydrocarbon oils was also confirmed. The results are shown in Table 2.

[0101] As shown in Table 2, only (a1) contains a copolymer of dimer esters, or a mixture of (a1) containing dimer esters and (a2) dimer esters in a 1:1 ratio, which dissolves in hydrocarbons at 90°C and separates at 25°C. Therefore, it can be said that the preferred combination is the copolymer of (a1) containing dimer esters, or the mixture of (a1) containing dimer esters and (a2) dimer esters, with (B) a hydrocarbon oil that is liquid at room temperature.

[0102] The inventors manufactured samples (solid lipsticks) consisting of the mixtures listed in the table using conventional methods. Each sample was then evaluated based on the following evaluation criteria.

[0103] (Methods for evaluating formability)

[0104] The following criteria were used to determine when the lipstick was removed from the mold used for molding.

[0145] The inventors studied the viscosity of the mixable component (B).

[0146] The results are shown in Table 3.

[0147] Table 3

[0148]

[0149] As shown in Table 3 above, the hydrocarbon used as component (B) needs to be a non-volatile substance. If a volatile hydrocarbon oil is used, desirable usability will not be achieved. Furthermore, it is noted that if the viscosity of the non-volatile hydrocarbon oil is below 100 mPa·s, the cosmetic will exhibit excellent non-re-adhesion properties, achieving moderate gloss and excellent makeup-holding properties. Preferably, it is below 50 mPa·s.

[0150] The inventors studied the mixing amount and mixing ratio of component (A) and component (B).

[0151] The results are shown in Table 4.

[0152] Table 4

[0153]

[0154] As shown in the results of test examples 1-1 to 1-10 in Table 4, the preferred mixing amount of (A) containing the dimer ester co-polymer is 15 to 50% by mass. Furthermore, the preferred mixing amount of (B) the hydrocarbon, which is liquid at room temperature, is 20 to 70% by mass. Moreover, the same test examples suggest that if the mixing ratio of component (A) to component (B) is 1:0.5 to 1:4, a non-secondary adhesion effect is achieved, resulting in a lip solid cosmetic with good usability.

[0155] The inventors investigated whether substances other than (a1) containing dimer esters could form dense oils. The results are shown in Table 5.

[0156] Table 5

[0157]

[0158] By comparing test examples 2-1 to 2-6 with 2-7 to 2-10 in Table 5, it can be seen that as a dense oil component, it is necessary to blend a copolymer of polyglycerol-2 isostearate / dimeric linoleic acid (a1) which contains a dimer ester.

[0159] Furthermore, by comparing Test Examples 2-1 to 2-4 with Test Examples 2-7 and 2-8, it was found that (a2) dimer ester also functions as a binding oil component when used in conjunction with (a1) copolymer containing dimer ester. In this case, the copolymer containing dimer ester in (a1) needs to account for more than 50% by mass in the binding oil.
