Description

Lip cosmetics

[0001] The present invention relates to a lip cosmetic, and more particularly to a lip cosmetic that has a good fit and long-lasting makeup, and is particularly excellent in transfer resistance (secondary adhesion resistance effect).

[0002] When makeup cosmetics come into contact with tableware or clothing, they may transfer color to the object (secondary adhesion). Secondary adhesion not only transfers the makeup color to the object, but can also cause makeup to come off. Lipstick, in particular, is prone to secondary adhesion because lips often come into contact with tableware. Therefore, cosmetics that suppress color transfer due to secondary adhesion, known as secondary adhesion-free effects, have been developed.

[0003] Patent Document 1 describes a liquid oil-in-oil cosmetic that contains predetermined amounts of (a) a non-volatile hydrocarbon oil, (b) methylphenylpolysiloxane, and (c) a dextrin fatty acid ester, and the blending ratio (mass ratio) of (a) the non-volatile hydrocarbon oil and (b) the methylphenylpolysiloxane falls within a specific range.

[0004] (a) Non-volatile hydrocarbon oil and (b) methylphenylpolysiloxane are poorly compatible and easily separate, but the cosmetic of Patent Document 1 further contains (c) dextrin fatty acid ester, resulting in a stable oil-in-oil composition. When the cosmetic is applied to the lips and rubbed together, the methylphenylpolysiloxane (called the "exuding oil" or "coating oil") exudes and separates to the surface, covering the non-volatile hydrocarbon oil (called the "adhering oil") and imparting transfer resistance and a good shine. Cosmetics in this form, in which the adhering oil and the coating oil (exuding oil) separate and the coating oil covers the adhering oil, are sometimes called "two-phase separation cosmetics."

[0005] However, the cosmetic of Patent Document 1 requires the incorporation of a large amount of silicone oil as a coating oil, which is not compatible with silicone-free cosmetics that have been attracting attention in recent years. Meanwhile, two-phase separation type cosmetics that do not use silicone oil as a coating oil have also been developed. For example, the lip cosmetic described in Patent Document 2 uses a copolymer containing a dimer acid ester and / or a dimer acid ester as an adhesion oil and a hydrocarbon oil as a coating oil, which is said to have an excellent secondary adhesion-resistant effect and a glossy feel.

[0006] However, even in the lip cosmetic of Patent Document 2, the adhered oil and the coating oil are in contact after separation, so it is inevitable that a portion of the coloring material will migrate from the adhered oil to the coating oil. Therefore, it is difficult to completely prevent the coloring material that has migrated to the coating oil from transferring to a contact object such as a cup (secondary adhesion).

[0007] Japanese Patent No. 4766720 JP 2022-115395 A

[0008] In view of the above-mentioned current state of the art, an object of the present invention is to provide a two-phase separation type lip cosmetic that has further improved transfer resistance (secondary adhesion-free effect).

[0009] As a result of extensive research into solving the above-mentioned problems, the present inventors have discovered that by using a specific urethane polymer as the adhesion oil, the urethane polymer exhibits excellent colorant capturing properties, making it possible to suppress the migration of colorant from the adhesion oil to the coating oil, thereby significantly improving transfer resistance, and have completed the present invention.

[0010] That is, the present invention provides a lip cosmetic comprising: (A) a urethane polymer obtained by reacting castor oil with isophorone diisocyanate; (B) a non-volatile oil that separates when mixed with component (A) at 25°C; (C) an oil-soluble gelling agent; and (D) a coloring material.

[0011] The lip cosmetic of the present invention uses a urethane polymer obtained by reacting castor oil with isophorone diisocyanate as the adhesion oil, thereby suppressing migration of coloring materials from the adhesion oil to the coating oil and significantly improving transfer resistance (secondary adhesion resistance effect). Furthermore, when a non-volatile hydrocarbon oil and / or vegetable oil is used as the coating oil, the amount of silicone oil blended can be reduced. In addition, the cosmetic provides excellent fit and makeup retention upon application. The fit refers to the feeling that the cosmetic gently conforms to the vertical wrinkles and irregularities of the lips and adheres closely to the lips.

[0012] The lip cosmetic of the present invention (hereinafter also simply referred to as "cosmetic") contains, as essential components, (A) a urethane polymer obtained by reacting castor oil with isophorone diisocyanate; (B) a non-volatile oil that separates when mixed with component (A) at 25°C; (C) an oil-soluble gelling agent; and (D) a colorant.

[0013] (A) Urethane Polymer The urethane polymer (hereinafter also referred to simply as "urethane polymer" or "component A") obtained by reacting castor oil with isophorone diisocyanate (IPDI) in the cosmetic of the present invention belongs to the category of components known as "(castor oil / IPDI) copolymer" (INCI name: Castor Oil / IPDI Copolymer) in cosmetic ingredient labeling.

[0014] A known "(castor oil / IPDI) copolymer" that can be incorporated into cosmetics is available under the trade name "Polyderm PPI-CO" (manufactured by ALZO International Inc.), which is a urethane polymer with a molecular weight of approximately 2082. The urethane polymer (component A) used in the cosmetics of the present invention is preferably one obtained by reacting castor oil with isophorone diisocyanate and having a weight-average molecular weight of 10,000 to 150,000.

[0015] A urethane polymer having a weight-average molecular weight of 10,000 to 150,000 can be produced by reacting the raw materials, castor oil, with isophorone diisocyanate in a specific ratio. The castor oil used to produce this urethane polymer is a type of vegetable oil typically extracted from castor bean seeds, and is a mixture primarily composed of triesters of glycerin with fatty acids such as ricinoleic acid, linoleic acid, oleic acid, palmitic acid, and stearic acid. The castor oil used as a raw material for the urethane polymer preferably used in the present invention does not include modified castor oils such as hydrogenated castor oil, or various castor oil derivatives obtained by chemically treating castor oil.

[0016] The urethane polymer is considered to be primarily composed of a urethane polymer obtained by the reaction of hydroxyl groups present in the ricinoleic acid residues constituting the fatty acid esters, the main component of castor oil, with the isocyanate groups of isophorone diisocyanate to form urethane bonds. However, the specific structure of the urethane polymer is not clear, since the castor oil used as a raw material is itself a mixture of glycerides (fatty acid esters) of various fatty acids and glycerin, and the structure of the resulting urethane polymer also changes depending on the equivalent ratio of the castor oil and isophorone diisocyanate used. Therefore, it is impossible or even impractical to uniquely describe the structure of the urethane polymer by a general formula.

[0017] The weight-average molecular weight of the urethane polymer preferably used in the cosmetic of the present invention is 10,000 to 150,000, preferably 15,000 to 140,000, more preferably 40,000 to 130,000, even more preferably 60,000 to 120,000, and particularly preferably 90,000 to 120,000. In the present invention, the weight-average molecular weight of the urethane polymer is measured by gel permeation chromatography (GPC) and is calculated as a styrene equivalent.

[0018] The urethane polymer having a weight average molecular weight in the above range has a viscosity at 25°C of 10,000 to 5,000,000 mPa·s, for example, 50,000 to 4,000,000 mPa·s, 200,000 to 3,000,000 mPa·s, 600,000 to 2,500,000 mPa·s, or 50,000 to 2,000,000 mPa·s. However, when heated to 60°C, the viscosity drops to a range of 5,000 to 1,500,000 mPa·s, for example, 8,000 to 1,200,000 mPa·s, 20,000 to 1,000,000 mPa·s, 50,000 to 900,000 mPa·s, or 5,000 to 200,000 mPa·s, a unique characteristic. Therefore, the viscosity becomes low during production at high temperatures, which has the advantage of facilitating mixing with other components. Unless otherwise specified, the viscosity in the present invention is a value measured at 25°C using a Brookfield viscometer, for example, a TVB-10M (manufactured by Toki Sangyo Co., Ltd.).

[0019] The blending amount of the "urethane polymer" (component A) in the cosmetic of the present invention is 5 to 40% by mass, preferably 10 to 35% by mass, and more preferably 15 to 30% by mass, based on the total amount of the cosmetic.

[0020] The "adhesion oil" in the cosmetic of the present invention preferably contains, in addition to the essential urethane polymer (component A), at least one selected from (e1) a copolymer containing a dimer acid ester and (e2) a dimer acid ester (hereinafter also referred to as "component E" or "dimer acid esters"). By including component E, the stability of the cosmetic is further improved.

[0021] (e1) Copolymer containing dimer acid ester The "copolymer containing dimer acid ester" (component e1) is a high-viscosity non-volatile ester oil. As the copolymer containing dimer acid ester (component e1), it is preferable to select one that separates when heated to 90°C together with the non-volatile oil (B) described below, mixed with stirring, and then allowed to stand at rest, and the mixture cools to 25°C.

[0022] An example of a copolymer containing a dimer acid ester (component e1) is (polyglyceryl-2 isostearate / dimer dilinoleate) copolymer, and a commercially available product thereof is Hilucent ISDA (manufactured by Kokyu Alcohol Kogyo Co., Ltd.).

[0023] (e2) Dimer Acid Esters Dimer acid esters (component e2) are liquid fatty acid esters containing monobasic and tribasic acids, with the dibasic acid of a C36 dicarboxylic acid produced by dimerization of a C18 unsaturated fatty acid derived from vegetable oils and fats as the main component. Examples of dimer acid esters (component e2) include hydrogenated castor oil dimer dilinoleate and dimer dilinoleyl dimer dilinoleate. Commercially available products include Lithocasta DA-L (manufactured by Kokyu Alcohol Kogyo Co., Ltd.) and Lithocasta DA-H (manufactured by Kokyu Alcohol Kogyo Co., Ltd.).

[0024] The component E to be blended in the adhesive oil component of the cosmetic of the present invention may be either (e1) or (e2) alone, or may be both (e1) and (e2).

[0025] The blending amount of the adhesive oil component in the cosmetic of the present invention (total blending amount of Components A and E) is preferably 10 to 80% by mass, more preferably 20 to 70% by mass, and even more preferably 25 to 60% by mass, of the total amount of the cosmetic. The blending amount of the urethane polymer (Component A) relative to the total amount of the adhesive oil component is preferably 10% by mass or more, and more preferably 20% by mass or more.

[0026] (B) Non-volatile oil "Component B" (also referred to as "coating oil") of the cosmetic of the present invention is a non-volatile oil (hereinafter simply referred to as "non-volatile oil") that separates when mixed with "Component A" at 25°C, and is a non-volatile oil that is liquid at room temperature (25°C) and can be incorporated into cosmetics. "Component B" of the present invention separates when heated to 90°C with the adhesion oil (Component A), mixed with stirring, and then allowed to stand, and the mixture cools to 25°C.

[0027] In this specification, "separate" and "miscible" are defined as follows: "Component A" and "Component B" are heated to 90°C in a mass ratio of (A):(B) = 1:1, mixed with stirring, and then allowed to stand. When the mixture reaches 25°C, a mixture that is separated into two layers with a uniform boundary is considered to be "separated," and a transparent state with no boundary is considered to be "not separated" or "miscible."

[0028] As the non-volatile oil (component B), it is preferable to use a non-silicone oil (oil that does not have a siloxane structure in the molecule). Specific examples of non-silicone oils that are preferably used as "component B" include hydrocarbon oils such as squalane, hydrogenated polyisobutene, hydrogenated polydecene, liquid paraffin, light isoparaffin, and heavy liquid paraffin, as well as vegetable oils such as jojoba seed oil, olive fruit oil, and macadamia nut oil. The cosmetic of the present invention also includes embodiments that do not contain silicone oil.

[0029] The amount of non-volatile oil (Component B) in the cosmetic of the present invention is 20 to 80% by mass, preferably 30 to 70% by mass, and more preferably 35 to 65% by mass, based on the total amount of the cosmetic. If the amount of non-volatile oil (Component B) is less than 20% by mass, separation during application becomes difficult, making it difficult to achieve the secondary adhesion-resistant effect. If the amount exceeds 80% by mass, the secondary adhesion-resistant effect is achieved, but the amount of adhered oil decreases, making it difficult to achieve sufficient color development. Furthermore, if the amount of non-volatile oil (Component B) is large, the stability of the system tends to decrease. Therefore, for example, if the amount of non-volatile oil (Component B) exceeds 60% by mass, it is preferable to add the above-mentioned Component E (dimer acid esters) to the adhered oil.

[0030] The non-volatile oil (component B) preferably has a viscosity at 25°C of 3,000 mPa·s or less, more preferably 2,000 mPa·s or less. However, the use of a high-viscosity oil exceeding 3,000 mPa·s as the non-volatile oil (component B) in the cosmetic of the present invention is not excluded. However, when a high-viscosity oil is used, it is preferable to add a low-viscosity oil and / or a volatile oil of 500 mPa·s or less to adjust the viscosity to the above range before blending. As the volatile oil, volatile hydrocarbon oils such as isododecane and isohexadecane are preferably used.

[0031] (C) Oil-Soluble Gelling Agent The oil-soluble gelling agent (also referred to as "Component C") incorporated into the cosmetic of the present invention is preferably at least one selected from dextrin fatty acid esters and waxes.

[0032] Dextrin fatty acid esters are esters of dextrin and higher fatty acids, where the higher fatty acids are selected from fatty acids having 12 to 22 carbon atoms. As long as the higher fatty acids contain fatty acids having 12 to 22 carbon atoms, they may also contain fatty acids having 6 to 10 carbon atoms. Examples of such dextrin fatty acid esters include dextrin palmitate, dextrin myristate, and dextrin (palmitate / ethylhexanoate). Commercially available products that can be used include those under the trade names Rheopearl KL, Rheopearl KL2, Rheopearl TT, Rheopearl TT2, and Rheopearl MKL2 (all manufactured by Chiba Flour Milling Co., Ltd.).

[0033] The wax used as the oil-soluble gelling agent (C) of the present invention is not particularly limited as long as it is one that is usually incorporated into cosmetics, and among these, sunflower wax (sunflower seed wax), candelilla wax, microcrystalline wax, polyethylene wax, and sucrose tetrastearate triacetate (also called sucrose fatty acid ester or sugar wax) are preferably used.

[0034] The cosmetic of the present invention can be made into a liquid cosmetic or a solid cosmetic by adjusting the type and / or amount of the oil-soluble gelling agent (ingredient C). In the present invention, "liquid" means that the cosmetic is in a state that has fluidity (liquid to paste-like) at room temperature (25°C). For example, a "liquid" may be defined as having a viscosity in the range of 100 to 400,000 mPa s.

[0035] When the cosmetic of the present invention is formulated as a liquid cosmetic, it is preferable to use a dextrin fatty acid ester as the oil-soluble gelling agent (C), with the blending amount being 0.1 to 10% by mass, preferably 0.5 to 8% by mass, and more preferably 1 to 5% by mass. When the cosmetic is formulated as a solid cosmetic, it is preferable to use a wax as the oil-soluble gelling agent (C), with the blending amount being 6 to 15% by mass, and preferably 7 to 12% by mass. In both liquid and solid forms, if the blending amount of the oil-soluble gelling agent (C) is too small, stability will be poor, and if it is too large, the cosmetic may become sticky during use.

[0036] (D) Colorant The colorant (also referred to as "component D") in the present invention is not particularly limited as long as it is a powdery colorant. Examples thereof include inorganic white pigments (titanium dioxide, zinc oxide), inorganic red pigments (iron oxide (red iron oxide), iron titanate), inorganic brown pigments (γ-iron oxide), inorganic yellow pigments (yellow iron oxide, ochre), inorganic black pigments (black iron oxide, carbon, low-order titanium oxide), inorganic purple pigments (mango violet, cobalt violet), inorganic green pigments (chromium oxide, chromium hydroxide, cobalt titanate), inorganic blue pigments (ultramarine, iron blue), pearl pigments (titanium oxide-coated mica, titanium oxide-coated bismuth oxychloride, titanium oxide-coated talc, colored titanium oxide-coated mica, bismuth oxychloride, fish scale foil), metal powder pigments (aluminum powder, copper powder), organic pigments (Red No. 202, Red No. 205, Examples of suitable pigments include Red No. 220, Red No. 228, Red No. 405, Orange No. 203, Orange No. 204, Yellow No. 205, Yellow No. 40, and 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, and Blue No. 1), natural pigments (chlorophyll, carotenoids (β-carotene), carthamine, cochineal, chalcone, curcumin, betanin, flavonols, flavones, anthocyanidins, anthraquinones, and naphthoquinones), and functional pigments (photochromic pigments, synthetic fluorphlogopite, iron-containing synthetic fluorphlogopite, and fine particle composite powders (hybrid fine powders)). The colorant (component D) used in the present invention may or may not be surface-treated for hydrophobicity.

[0037] The blending amount of the coloring material (component D) in the cosmetic of the present invention is preferably 0.1 to 15% by mass, more preferably 1 to 12% by mass, and even more preferably 4 to 10% by mass, based on the total amount of the cosmetic.

[0038] In addition to the above-mentioned components A to E, the lip cosmetic of the present invention can contain other components commonly used in lip cosmetics, provided that the effects of the present invention are not impaired. Examples of other components that may be optionally contained include, but are not limited to, oils (other than components A, B, C, and E), powders (other than component D), polymeric compounds, moisturizers, fragrances, antioxidants, preservatives, and cosmetic ingredients.

[0039] The powders (other than component D) include spherical powders and plate-like powders, etc. Examples of spherical powders include spherical inorganic powders such as silica (silicic anhydride), and spherical resin powders such as polymethyl methacrylate, organopolysiloxane elastomers, polystyrene, polyamide resins (nylon), polyethylene, copolymers of styrene and acrylic acid, benzoguanamine resins, polytetrafluoroethylene, and silicone resins.

[0040] Examples of plate-like powders include inorganic powders such as mica, synthetic mica, talc, sericite, aluminum oxide, magnesium oxide, zirconium oxide, magnesium carbonate, calcium carbonate, calcium sulfate, chromium oxide, chromium hydroxide, aluminum silicate, magnesium silicate, aluminum magnesium silicate, kaolin, silicon carbide, barium sulfate, bentonite, smectite, and boron nitride, organic powders such as N-acyllysine, and composite powders such as titanium oxide-coated mica titanium, zinc oxide-coated mica titanium, and barium sulfate-coated mica titanium. The blend amount of powders (other than component D) in the cosmetic of the present invention is preferably 30% by mass or less, and more preferably 20% by mass or less, of the total amount of the cosmetic.

[0041] The cosmetic of the present invention can be produced by a method commonly used for oil-based cosmetics, for example, by heating the ingredients as needed, mixing them with stirring, filling them into a container, and slowly cooling them.

[0042] The cosmetic of the present invention is an oil-in-oil emulsion cosmetic that uses a specific urethane polymer as the adhesion oil and a non-volatile oil (preferably a non-silicone oil) as the coating oil. The cosmetic of the present invention is suitable for use as a makeup cosmetic, particularly as a lip cosmetic that has excellent transfer resistance (secondary adhesion resistance effect). Specifically, it is preferably provided in the form of a lipstick, lip gloss, lip base, lipstick overcoat, lip balm, etc.

[0043] The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these examples. The blending amounts are expressed in mass % unless otherwise specified. Furthermore, the molecular weights listed in the tables are weight-average molecular weights.

[0044] Lip cosmetics (liquid) were prepared according to a conventional method using the formulations shown in Tables 1 and 2. The properties of the cosmetics in each example in Tables 1 and 2 were measured and evaluated by the following methods.

[0045] <Test Method and Evaluation Criteria> A practical use test was conducted by a panel of experts. The evaluation items were the secondary adhesion-free effect immediately after application, fit, makeup durability, and stability. The cosmetics were applied by applying each example to the lips, and then rubbing the upper and lower lips together and applying pressure for about 5 seconds. The secondary adhesion-free effect (transfer resistance) was evaluated by visual observation of the absence of color transfer to the cup. Fit was evaluated by a sensory evaluation of the fit upon application. Makeup durability was evaluated by comparing visual observations immediately after application with those several hours after application. Stability was evaluated by placing each example cosmetic in a screw tube and visually observing the appearance for the presence or absence of separation and color unevenness.

[0046] The secondary adhesion resistance (transfer resistance), fit, and makeup lasting time were evaluated according to the following criteria, using the evaluation results of the cosmetic of Comparative Example 1 (Table 1) as a control. A: Significantly superior to Comparative Example 1 B: Superior to Comparative Example 1 C: Equivalent to Comparative Example 1 D: Inferior to Comparative Example 1

[0047] The stability was evaluated based on the following criteria: A: Uniform, with no separation or uneven color. B: Separation or uneven color was observed in some areas, but at a level that was not problematic for practical use. C: Separation was observed, and significant uneven color occurred.

[0048] The urethane polymers used in the examples were produced by the following method. <Urethane Polymer 1> A glass reaction vessel equipped with a stirrer, a condenser, and a nitrogen inlet tube was charged with 250 g of castor oil (Castor Oil LAV manufactured by Ito Oil Mills, Ltd., hydroxyl group equivalent 161 mg KOH / g) and 40 g (0.18 mol) of isophorone diisocyanate, and the mixture was reacted at 110 to 120°C for 5 hours. The reaction was terminated when it was confirmed that there was no NCO absorption by infrared absorption spectroscopy, thereby producing Urethane Polymer 1. The weight average molecular weight of the resulting Urethane Polymer 1 was 17,500.

[0049] <Urethane Polymer 2> Urethane polymer 2 was produced in the same manner as urethane polymer 1, except that the amount of isophorone diisocyanate charged was 46 g (0.21 mol). The weight average molecular weight of the resulting urethane polymer 2 was 77,800.

[0050] <Urethane Polymer 3> Urethane polymer 3 was produced in the same manner as urethane polymer 1, except that the amount of isophorone diisocyanate charged was 48 g (0.22 mol). The weight average molecular weight of the resulting urethane polymer 3 was 107,600.

[0051] The weight-average molecular weight (above value) of each produced urethane polymer was measured by gel permeation chromatography (GPC) and calculated in terms of styrene. The detailed measurement method is as follows. GPC apparatus: HLC-8320GPC (manufactured by Tosoh Corporation) Column: TSKgel (registered trademark) SuperMultiporeHZ-N (manufactured by Tosoh Corporation) Detector: RI detector (built into HLC-8320GPC) Flow rate: 0.3 ml / min Sample concentration: 0.5 mass% (THF solution) Injection volume: 5 μl Column temperature: 40°C Standard sample: TSKgel standard polystyrene (weight-average molecular weights: 98,900, 37,200, 13,700, 9,490, 5,430, 3,120, 1,010, 589; all manufactured by Tosoh Corporation)

[0052]

[0053]

[0054] The experimental results shown in Tables 1 and 2 indicate that the cosmetic of the present invention, by incorporating a urethane polymer (component A) as an adhesive oil, has improved secondary adhesion resistance, fit, and makeup durability compared to Comparative Examples 1 and 2, which incorporated only dimer acid esters (component E), and has a level of stability that is not problematic in practical use.

[0055] The results in Table 1 show that when 60% by mass of non-volatile oil (Component B) was blended, the stability of the cosmetic was further improved by adding dimer acid esters (Component E) in addition to the urethane polymer (Component A) that constitutes the adhesive oil (Comparison between Examples 1 to 4 and Example 5). These results were similar even when a urethane polymer (Component A) with a different molecular weight was used (Comparison between Examples 2 to 4).

[0056] The results shown in Table 2 show that Examples 6 to 8, which contained a dimer acid ester (Component E) in an amount exceeding the amount of urethane polymer (Component A), exhibited a slightly reduced fit compared to Examples 1 to 5 and 9 to 14, in which the amount of Component A was equal to or greater than that of Component E, but were still superior to Comparative Examples 1 and 2. Furthermore, even when the amount of coating oil was reduced to 20 mass% (Example 12), when a medium-viscosity hydrocarbon oil was used as the coating oil (Example 13), and when a high-viscosity hydrocarbon oil was included in the coating oil (Example 14), improved performance (secondary adhesion-free effect, fit, and cosmetic longevity) was obtained compared to Comparative Examples 1 and 2, and excellent stability was also obtained.
