Description

[Technical Field]

[0001] The present invention relates to a cosmetic composition or a fiber treatment composition for headwear. [Background technology]

[0002] Aqueous compositions for treating keratinous materials containing a cationic polymer and an anionic polymer are known. For example, Patent Document 1 describes that by using a composition for treating keratinous materials characterized by containing at least one anionic polymer and at least one cationic polymer in a solvent medium, the anionic polymer can be fixed to keratinous materials, particularly hair, skin, or nails. It is hypothesized that the above effect is due to a complex formed by the interaction between the anionic polymer and the cationic polymer.

[0003] Regarding hair cosmetics containing a cationic polymer and an anionic polymer, for example, Patent Document 2 discloses a hair treatment composition containing (A) L-theanine and (B) polymer compounds including a nonionic polymer, an amphoteric polymer, and a cationic polymer, and also mentions that an anionic polymer may be added as needed. It also discloses that the hair treatment composition can impart softness to hair while improving elasticity near the roots.

[0004] Patent Document 3 describes that a hair cosmetic containing a cationic polymer having a charge density within a specified range and an anionic polymer containing 80% by mass or more and 100% by mass or less of specified anionic constituent units and having a weight-average molecular weight of 4,000 or more and 80,000 or less can improve the feel and appearance of damaged hair, and can maintain these effects even after repeated hair washing.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 53-139734 [Patent Document 2] Japanese Patent Application Laid-Open No. 2008-297295 [Patent Document 3] Japanese Patent Application Laid-Open No. 2005-166333 Summary of the Invention [Problem to be solved by the invention]

[0006] As described in Patent Document 1, it is known that a composition containing a complex formed from a cationic polymer and an anionic polymer (hereinafter also referred to as a "polyion complex") can be used as a composition for treating keratinous materials such as hair, but there is still room for improvement in its performance. For example, hair conditioners, which are a type of hair cosmetic composition, are required to improve the texture of treated hair, reduce tangles, and ensure that treated hair does not spread even under high humidity conditions and has excellent humidity resistance. However, the prior art described in Patent Documents 1 to 3 did not achieve any particular effect. Furthermore, the hair treatment effect can be lost after one shampoo, so there is a need for an improvement in the durability of the treatment effect (washability).

[0007] Furthermore, compositions containing polyion complexes are available in the form of oil-in-water or water-in-oil emulsion compositions, but these emulsion compositions have a problem in terms of improving their stability over time. In particular, hair cosmetic compositions often contain cationic surfactants, higher alcohols, and the like to improve the feel of treated hair. However, the incorporation of these components into compositions containing polyion complexes has the problem of easily reducing their stability.

[0008] An object of the present invention is to provide a cosmetic composition or a fiber treatment composition for headwear products that is highly stable and can improve the texture improvement effect of an object to be treated, the durability of the effect, and the moisture resistance. [Means for solving the problem]

[0009] The present inventors have found that the above-mentioned problems can be solved by a composition containing a cationic polymer, an anionic polymer, a specified silicone compound, and water, each of which has a 1% by mass aqueous solution viscosity of a specified value or higher. Specifically, the present invention relates to a cosmetic composition or a fiber treatment composition for headwear, comprising (A) a cationic polymer having a viscosity of 1,000 mPa s or more in a 1% by mass aqueous solution at 30°C, (B) an anionic polymer, (C) one or more modified silicones selected from the group consisting of both-end hydroxy-modified silicones, polyglycerin-modified silicones, amino-modified silicones, aminopolyether-modified silicones, and polyether-modified silicones, (D) dimethylpolysiloxane, (E) a cationic surfactant, and (F) a higher alcohol, wherein the mass ratio of component (A) to component (B) [(A) / (B)] is 4.5 or more. [Effects of the Invention]

[0010] According to the present invention, it is possible to improve the texture-improving effect and duration of this effect of the object to be treated, as well as the humidity resistance, and in particular, when used to treat hair or fibers for head accessories, it is possible to provide a cosmetic composition or a fiber treatment composition for head accessories that is highly stable and can improve the entanglement-inhibiting effect and duration of this effect of the hair or fibers for head accessories, and can inhibit hair from spreading under high humidity conditions. DETAILED DESCRIPTION OF THE INVENTION

[0011] [Cosmetic composition or fiber treatment composition for headwear products] The cosmetic composition or fiber treatment composition for headwear of the present invention (hereinafter also simply referred to as "the composition of the present invention") contains (A) a cationic polymer having a viscosity of 1,000 mPa·s or more in a 1% by mass aqueous solution at 30°C, (B) an anionic polymer, (C) one or more modified silicones selected from the group consisting of polyglycerin-modified silicones and amino-modified silicones, (D) dimethylpolysiloxane, (E) a cationic surfactant, and (F) a higher alcohol, wherein the mass ratio of component (A) to component (B) [(A) / (B)] is 4.5 or more. In this specification, the phrase "containing component X" also includes blending component X. By having the above-described configuration, the composition of the present invention can improve the texture-improving effect of the treated object, the durability of the effect, and the humidity resistance. In particular, when used to treat hair or fibers for head accessories, the composition can improve the effect of inhibiting hair entanglement and the durability of the effect, inhibit hair frizz under high humidity conditions, and be highly stable.

[0012] The reason why the composition of the present invention exhibits the above-mentioned effects is not clear, but is thought to be as follows. The composition of the present invention contains a polyion complex formed from a specified ratio of component (A) and component (B). In the polyion complex, a crosslinked structure is formed between component (A) and component (B) due to ionic interactions, which is believed to be the reason why films obtained using the composition of the present invention exhibit a high elastic modulus. Furthermore, the polyion complex is poorly soluble in water, and a hydrophobic film can be formed by applying a composition containing the polyion complex to an object. The formation of this hydrophobic film is believed to improve the texture and moisture resistance of the treated object. Component (A) used in the present invention has a viscosity of 1,000 mPa·s or greater in a 1% by mass aqueous solution at 30°C. The use of component (A) improves the lubricity of the resulting film, further improving the texture of the treated object. When the composition of the present invention is used to treat hair or fibers for head accessories, it is believed to improve the effect of inhibiting entanglement of hair or fibers for head accessories. Furthermore, because polyion complexes containing component (A) are highly stable, the structure of the polyion complex is less likely to be destroyed, even when oily components such as components (E) and (F) are added to form an emulsion composition, improving stability.

[0013] Furthermore, the composition of the present invention contains silicone compounds as components (C) and (D). The modified silicone component (C) has high adsorption to keratinous materials, while component (D) is a compound with high hydrophobicity and low surface tension. Therefore, when the composition of the present invention is applied to an object to be treated, components (C) and (D) hydrophobically coat the surface of the object, which is thought to further improve the texture improvement effect, the durability of this effect, and the moisture resistance of the object.

[0014] The composition of the present invention is preferably a cosmetic composition for keratinous materials such as skin, hair, eyelashes, eyebrows, nails, etc., or a fiber treatment composition for head accessories, more preferably a cosmetic composition for skin or hair, or a fiber treatment composition for head accessories, even more preferably a cosmetic composition for skin or hair, and even more preferably a hair cosmetic composition. Among the cosmetic compositions, examples of product forms of skin cosmetic compositions include body soap, facial cleanser, bath additives, deodorant preparations, makeup cosmetics, sunscreens, makeup bases, emulsions, beauty serums, and creams. Furthermore, examples of product forms of the hair cosmetic composition include hair shampoo, hair rinse, hair conditioner, hair treatment (including leave-in type), hair styling agent, hair color, permanent agent, etc. Among these, from the viewpoint of the effectiveness of the effects of the present invention, hair conditioner, hair treatment, or hair styling agent is preferred.

[0015] The fibers for head accessories to which the composition of the present invention is applied may be either naturally-derived fibers or synthetic fibers, but naturally-derived fibers are preferred. Naturally-derived fibers refer to fibers collected from natural plants and animals, or artificially produced fibers made from collagen, casein, soybeans, peanuts, corn, waste silk fibroin, etc., and are used in head accessories. Of these, artificially produced fibers made from collagen, casein, soybeans, peanuts, corn, waste silk fibroin, etc. are preferred, with regenerated protein fibers such as regenerated collagen fibers made from collagen and regenerated silk fibers made from silk fibroin being more preferred, and regenerated collagen fibers being even more preferred.

[0016] Regenerated collagen fibers can be produced by known techniques. The composition of regenerated collagen fibers does not need to be 100% collagen, and may contain natural polymers, synthetic polymers, additives, etc. to improve quality. Furthermore, regenerated collagen fibers may be post-processed.

[0017] The preferred form of regenerated collagen fibers is filaments. Filaments are generally taken out from bobbins or boxes. Filaments that emerge from the drying process in the regenerated collagen fiber manufacturing process can also be used directly.

[0018] Examples of synthetic fibers include fibers containing a synthetic resin as a main component. From the viewpoint of ease of production of synthetic fibers and of obtaining a texture similar to that of human hair, the synthetic resin is preferably a thermoplastic resin, more preferably one or more selected from the group consisting of polyester resin, polyamide resin, polyimide resin, polyamideimide resin, vinyl chloride resin, polycarbonate resin, polyphenylene sulfide resin, and modacrylic resin (a copolymer of acrylonitrile and vinyl chloride).

[0108] (Method of producing the composition) The method for producing the composition is not particularly limited, but when the composition is an emulsion composition, it is preferable to produce a composition that has a texture-improving effect on the object to be treated and a long-lasting effect of the effect, particularly a high effect and long-lasting effect of inhibiting entanglement of hair or fibers for head accessories when used to treat hair or fibers for head accessories, an excellent effect of improving moisture resistance, and is also highly stable, by a method that includes the following steps 1 to 3, either step 4-1 or 4-2, and step 5 in that order. Step 1: (B) Preparing Solution 1 Containing an Anionic Polymer Step 2: Mixing the solution 1 with (H) acid or an aqueous solution thereof to prepare a mixture 2 containing (B) anionic polymer, (H) acid, and water. Step 3: Mixing the mixture 2 with (A) a cationic polymer to prepare a mixture 3 containing (A) a cationic polymer, (B) an anionic polymer, (H) an acid, and water. Step 4-1: A step of preparing an emulsion (Ia) by mixing an aqueous phase (I) containing water with an oily phase (I) containing (D) a cationic surfactant and (E) a higher alcohol, and then mixing the emulsion (Ia) with the mixture 3 to prepare an emulsion 4-1. Step 4-2: A step of preparing an emulsion 4-2 by mixing the mixture 3 with an aqueous phase (I) containing water to prepare an aqueous phase (Ia), and then mixing the aqueous phase (Ia) with an oily phase (I) containing (D) a cationic surfactant and (E) a higher alcohol. Step 5: A step of mixing the emulsion 4-1 or emulsion 4-2 with an oily phase (II) containing (C) one or more modified silicones selected from the group consisting of polyglycerin-modified silicones and amino-modified silicones, and (D) dimethylpolysiloxane.

[0109] The above method allows efficient formation of a polyion complex without being inhibited by other components, and is believed to result in the production of a composition that is highly effective in improving the texture of the object to be treated and that has a long-lasting effect, particularly in suppressing entanglement of hair or fibers for head accessories when used to treat hair or fibers for head accessories, and that has an excellent effect in improving humidity resistance and is also highly stable. In this specification, "aqueous phase" means a phase that constitutes the aqueous phase in the production process of an emulsion composition, and "oil phase" means a phase that constitutes the oil phase in the production process of an emulsion composition.

[0110] In step 1, solution 1 containing the anionic polymer (B) can be prepared by dissolving or dispersing the anionic polymer (B) in water. When preparing a solution in which component (B) is dissolved or dispersed in water, component (B) may be dispersed in advance in an aqueous medium other than water, such as dipropylene glycol, and then dissolved or dispersed in water. A commercially available aqueous solution or dispersion of component (B) can also be used as the solution in which component (B) is dissolved or dispersed in water. Alternatively, for example, the reaction solution obtained when component (B) is produced using water as a reaction solvent can be used as the solution in which component (B) is dissolved or dispersed in water. In step 3, the cationic polymer (A) may be mixed directly with the mixture 2. However, from the viewpoint of ease of production, it is preferable to mix a solution in which the component (A) is dissolved or dispersed in water with the mixture 2. A commercially available aqueous solution or dispersion of component (A) can also be used as the solution in which component (A) is dissolved or dispersed in water.

[Example]

[0118] The present invention will be described below with reference to examples, but the present invention is not limited to the scope of the examples. Measurements and evaluations in the examples were carried out by the following methods.

[0119] (Measurement of viscosity of 1% by mass aqueous solution of cationic polymer) A 1% by mass aqueous solution of the cationic polymer (component (A) or component (A')) used in each example was prepared, and the viscosity of the aqueous solution was measured at 30°C using a B-type viscometer (TV-20, manufactured by Toki Sangyo Co., Ltd.). In these examples, cationic polymers other than component (A) are referred to as "component (A')."

[0120] (pH measurement) Each hair conditioner was diluted 20 times with water, and the pH at 25°C was measured using a pH meter (F-51, manufactured by Horiba Ltd.).

[0121] (Combing force measurement after treatment with hair conditioner and two washes) (1) 7 mL of "Kao Foam Hair Bleach L" (first agent) and 15 mL of "Kao Foam Hair Color d" (second agent) manufactured by Kao Corporation were mixed and applied to a 20 cm long, 30 g mass of Japanese hair tress. After leaving it to stand for 20 minutes, it was thoroughly rinsed with warm water at 35 to 40°C (bleaching treatment). This bleaching treatment was repeated four times to prepare damaged tresses for evaluation. The tresses were washed with a plain shampoo of the following composition and allowed to absorb 15 g ± 0.5 g of water. (2) 1.5 mL of each hair conditioner was applied to the above-mentioned moistened tresses, massaged in with the hands, and left for 30 seconds, then rinsed for 15 seconds with warm water at 35-40°C. Next, the tresses were scrubbed 20 times on both sides with 1 mL of the above-mentioned plain shampoo for 30 seconds, and then rinsed for 15 seconds. (3) 1 mL of plain conditioner with the following composition was applied, massaged in with hands for 30 seconds, and rinsed for 15 seconds. The tresses were then scrubbed again with 1 mL of the plain shampoo, 20 times on each side, for 30 seconds, and rinsed for 15 seconds. (4) The tresses were combed with a brush to completely untangle them, and the moisture content of the tresses after rinsing was adjusted to 15g ± 0.5g. The tresses were then placed in a combing force measuring device (Utsunomiya Seiki Co., Ltd., "KOT-0303"), and two brushes (Kao Lunet) were inserted into the top of the tresses. The combing was performed at a constant speed (60 rpm), and the load (g) applied when the comb was passed through to the ends was measured. Combing was performed 50 times, and the average value of the combing loads at all 50 points was recorded as the "combing force immediately after treatment." A smaller combing force indicates a better result. The combing load for damaged tresses (15g ± 0.5g moisture content) that were not treated in (2) above was 2055g. A combing force of 1900g or less was considered to be good resistance to washing.

[0124] (Combing force measurement after treatment with hair conditioner + 4 washes) In the above-mentioned "treatment with hair conditioner + measurement of combing force after washing hair twice" procedure, (1) and (2) were performed, then (3) was performed three times, and then operation (4) was performed, and the combing force was measured.

[0125] (Emulsified state of hair conditioner 2 days after application) After mixing, 1 g of each hair conditioner was dropped onto a black plastic writing pad two days later, and the appearance when traced with a finger 10 times and the feel when crushed with a finger were evaluated according to the following criteria. A: No agglomerated particles are visible, and the powder feels smooth when crushed with fingers. B: No visible agglomerates, but they feel rough when crushed with fingers C: Agglomerated particles are visible and feel rough when crushed with fingers D: Separated

[0126] (Hair resistance to humidity after treatment) 7 mL of "Kao Foam Hair Bleach L" (first agent) and 15 mL of "Kao Foam Hair Color d" (second agent) manufactured by Kao Corporation were mixed and applied to a 30 cm long, 20 g mass Japanese hair tress. After leaving it to stand for 20 minutes, it was thoroughly rinsed with warm water at 35-40°C (bleaching treatment). The bleaching treatment was repeated four times to prepare damaged tresses for evaluation. After washing the tresses with the plain shampoo, 1 mL of the hair conditioner of each example was applied and left to soak for 30 seconds. After leaving it in this state for 1 minute, the tresses were rinsed with running water at 35 to 40°C for 30 seconds and then dried with a hair dryer until completely dry. After drying, the tresses were straightened 10 times using a flat iron ("AHI-938" manufactured by Miki Electric Industrial Co., Ltd.) set to 160°C while passing the comb through, and a photograph of the tresses was taken immediately after setting. Next, the straightened hair was hung and left to stand in a high humidity environment of 35°C and 80% RH for 30 minutes, and then photographed again. In the two photographs, the tress width was measured at a point 23.5 cm from the root of the tresses, and the change in the tress width immediately after straightening and after storage in high humidity was calculated using the following formula. Change in trace width = (trace width after storage under high humidity) / (trace width immediately after straightening) When the value is 1.3 or more, it appears to have spread visually, and therefore it is judged that the moisture resistance is low.

[0127] Examples 1 to 13 and Comparative Examples 1 to 11 (Preparation and Evaluation of Hair Conditioners) Hair conditioners were prepared using the ingredients in the amounts shown in the table according to the following procedure. An anionic polymer (component (B1), or components (B1) and (B2)) previously dispersed in dipropylene glycol was added to a 500 mL beaker containing water, and the mixture was heated and stirred at 56° C. After confirming that the anionic polymer had completely dissolved, in Examples 2 to 9, the nonionic polymer (G) was further added and completely dissolved. Next, 90% lactic acid (57% of the total amount) and cationic polymer (component (A) or component (A')) were added. Furthermore, (E) cationic surfactant, (F) higher alcohol, the remaining dipropylene glycol, and benzyl alcohol were mixed in advance and dissolved at 85°C to obtain an oily phase, which was then added and stirred at 56°C for 10 minutes. After 10 minutes of stirring, heating was stopped and air cooling was initiated. After air cooling, the silicones (components (C) and (D)) listed in the table and the remaining 90% lactic acid were added, and the mixture was cooled with stirring until the liquid temperature reached 40°C or below, yielding 500 mL of hair conditioner. The obtained hair conditioners were evaluated according to the methods described above, and the results are shown in Tables 1 to 4.
