Description

Technical Field

[0001] The present invention relates to a cosmetic composition or a fiber treatment composition for a headdress product. Background Art

[0002] Aqueous compositions for treating keratinous substances containing cationic polymers and anionic polymers are known. For example, Japanese Patent Application Laid-Open No. 53-139734 (Patent Document 1) describes that by using a composition for treating keratinous substances characterized by containing at least one anionic polymer and at least one cationic polymer in a solvent medium, anionic polymers can be fixed to keratinous substances, which may include hair, skin or nails in particular. In addition, as a reason for obtaining the above-mentioned effect, it is assumed that it is related to the 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, Japanese Patent Application Laid-Open No. 2008-297295 (Patent Document 2) discloses a hair treatment composition containing (A) L-theanine and (B) a nonionic polymer, an amphoteric polymer, and a cationic polymer as a polymer compound, and states that an anionic polymer may be contained as required. In addition, it is disclosed that the hair treatment composition can impart softness to hair and improve the elasticity of the hair root vicinity.

[0004] Japanese Patent Application Laid-Open No. 2005-166333 (Patent Document 3) describes that a hair cosmetic containing a cationic polymer having a charge density within a specific range and an anionic polymer containing 80% by mass or more and 100% by mass or less of a specific anionic structural unit and having a weight average molecular weight of 4,000 or more and 80,000 or less can improve the touch and appearance of damaged hair, and these effects can be sustained even after repeated shampooing. Summary of the invention

[0005] The present invention relates to a cosmetic composition or a fiber treatment composition for a headdress product, comprising: (A) a cationic polymer having a viscosity of 1,000 mPa·s or more in a 1 mass % aqueous solution at 30° C., (B) an anionic polymer, (C) one or more modified silicones selected from silicones modified with hydroxy groups at both ends, polyglycerol-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 the component (A) to the component (B) [(A) / (B)] is 4.5 or more. DETAILED DESCRIPTION

[0006] As described in Patent Document 1, it is known that a composition containing a complex formed of a cationic polymer and an anionic polymer (hereinafter also referred to as a "polyion complex") is used as a composition for treating keratin substances such as hair, but there is still room for improvement in terms of improving its performance. For example, in a conditioner, which is a type of hair cosmetic composition, it is required to improve the texture of the treated hair, suppress tangling, and have excellent moisture resistance without being tangled under high humidity conditions. However, no particular effect can be obtained in the prior art of Patent Documents 1 to 3. In addition, the treatment effect of hair may be lost after one shampooing, and it is expected to improve the sustainability of the treatment effect (washing resistance).

[0007] Furthermore, compositions containing polyion complexes are sometimes in the form of oil-in-water or water-in-oil emulsion compositions, but in these emulsion compositions, improvement of stability over time is a problem. In particular, in hair cosmetic compositions, cationic surfactants, higher alcohols, etc. are sometimes added to improve the touch of treated hair. However, there is a problem that when these components are added to a composition containing a polyion complex, stability is easily reduced.

[0008] The present invention relates to providing a cosmetic composition or a fiber treatment composition for a headdress product which can improve the texture-enhancing effect of a treated object, the sustainability of the effect, and moisture resistance and has high stability.

[0009] The present inventors have found that the above-mentioned problems can be solved by a composition containing a cationic polymer having a 1 mass % aqueous solution viscosity of a specific value or more, an anionic polymer, a specific silicone compound, and water.

[0010] According to the present invention, there can be provided a cosmetic composition or a fiber treatment composition for hair products that can improve the texture-enhancing effect of a treated object and the sustainability of the effect, as well as moisture resistance, and, particularly when used for treating hair or fibers for hair products, can improve the tangling-inhibiting effect of hair or fibers for hair products and the sustainability of the effect, can suppress the tangling of hair under high humidity conditions, and has high stability.

[0011] [Cosmetic composition or fiber treatment composition for headdress products]

[0012] The cosmetic composition or fiber treatment composition for headwear products of the present invention (hereinafter, also referred to as the "composition of the present invention") contains (A) a cationic polymer having a viscosity of 1% by mass aqueous solution at 30°C of 1,000 mPa·s or more, (B) an anionic polymer, (C) one or more modified silicones selected from polyglycerol-modified silicone and amino-modified silicone, (D) dimethyl polysiloxane, (E) a cationic surfactant, and (F) a higher alcohol, wherein the mass ratio of the component (A) to the component (B) [(A) / (B)] is 4.5 or more.

[0013] In addition, in this specification, "containing component X" also includes compounding component X.

[0014] The composition of the present invention has the above-mentioned structure, and can improve the texture improvement effect of the treated object and the sustainability of the effect, as well as the moisture resistance. In particular, when used for treating hair or fibers for hair accessories, the composition can improve the hair tangling prevention effect and the sustainability of the effect, and can prevent the hair from becoming tangled under high humidity conditions, and has high stability.

[0015] The reason why the composition of the present invention achieves the above-mentioned effects is not certain, but is considered as follows.

[0016] The composition of the present invention comprises a polyion complex formed by a component (A) and a component (B) in a specific ratio. It is believed that in the polyion complex, a cross-linked structure is formed between the component (A) and the component (B) by ionic interaction, and thus, the film obtained by using the composition of the present invention exhibits a higher elastic modulus. Further, the polyion complex is poorly soluble in water, and a hydrophobic film can be formed by applying the composition comprising the polyion complex to an object. It is believed that by forming the hydrophobic film, the texture and moisture resistance of the object to be treated are improved.

[0017] The viscosity of a 1% by mass aqueous solution of the component (A) used in the present invention at 30°C is 1,000 mPa·s or more. It is believed that by using the component (A), the lubricity of the obtained film is improved, and thus the texture of the treated object is further improved. When the composition of the present invention is used for treating hair or fibers for hair accessories, the effect of inhibiting the tangling of the fibers for hair accessories is improved. In addition, the polyion complex containing the component (A) has high stability. Therefore, even when an oily component such as the component (E) or (F) is added to form an emulsified composition, the structure of the polyion complex is not easily destroyed, thereby improving the stability.

[0018] Furthermore, the composition of the present invention contains silicone compounds as components (C) and (D). The modified silicone as component (C) has high adsorption to keratin substances, and component (D) is a compound with high hydrophobicity and low surface tension. Therefore, it is believed that if the composition of the present invention is applied to a treatment object, the surface of the object is hydrophobically coated with components (C) and (D), and the texture improvement effect of the treatment object, the sustainability of the effect, and moisture resistance are further improved.

[0019] The composition of the present invention is preferably a cosmetic composition for keratin substances such as skin, hair, eyelashes, eyebrows, and nails, or a fiber treatment composition for hair products, more preferably a cosmetic composition for skin or hair, and a fiber treatment composition for hair products, further preferably a cosmetic composition for skin or hair, and even more preferably a hair cosmetic composition.

[0020] Among cosmetic compositions, examples of product forms of skin cosmetic compositions include body wash, facial cleanser, bath preparation, deodorant preparation, makeup, sunscreen, primer, emulsion, beauty serum, and cream.

[0021] In addition, examples of product forms of the hair cosmetic composition include shampoo, hair essence, hair conditioner, hair treatment (including leave-in), hair setting agent, hair dye, hair perm, etc. Among these, hair conditioner, hair treatment or hair setting agent is preferred from the viewpoint of effectiveness of the effect of the present invention.

[0022] As the fiber for headdress products that becomes the application object of the composition of the present invention, it can be any one of natural fiber and synthetic fiber, but preferably natural fiber. Fibers derived from nature refer to fibers collected from natural animals and plants, or fibers artificially manufactured using collagen, casein, soybeans, peanuts, corn, silk scraps, fibroin, etc. as raw materials, and fibers for headdress products. Among these, preferably, fibers artificially manufactured using collagen, casein, soybeans, peanuts, corn, silk scraps, fibroin, etc. as raw materials, more preferably regenerated collagen fibers using collagen as raw materials, regenerated protein fibers such as regenerated silk fibers using fibroin as raw materials, and more preferably regenerated collagen fibers.

[0023] 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. for quality improvement. Furthermore, regenerated collagen fibers may be post-processed fibers.

[0024] As the form of the regenerated collagen fiber, filaments are preferably used. The filaments are generally taken out from a reel or a box. In addition, in the production process of the regenerated collagen fiber, the filaments obtained from the drying process can also be directly used.

[0025] As synthetic fibers, fibers containing synthetic resins as main components can be cited. From the viewpoint of ease of manufacturing of synthetic fibers and the viewpoint of obtaining a texture close to that of hair, the synthetic resin is preferably a thermoplastic resin, and more preferably one or more selected from polyester resins, polyamide resins, polyimide resins, polyamideimide resins, vinyl chloride resins, polycarbonate resins, polyphenylene sulfide resins, and modified polyacrylonitrile resins (modacrylic resins) (copolymers of acrylonitrile and vinyl chloride).

[0347] Example

[0348] Hereinafter, the present invention will be described by way of examples, but the present invention is not limited to the scope of the examples. In addition, each measurement and evaluation in the examples were performed by the following methods.

[0349] (Measurement of Viscosity of 1 Mass % Aqueous Solution of Cationic Polymer)

[0350] A 1 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 at 30° C. was measured using a B-type viscometer (TV-20 manufactured by Toki Sangyo). In the present example, the cationic polymer other than component (A) is described as "component (A')".

[0351] (pH determination)

[0352] The conditioner of each example was diluted 20 times with water, and the pH value at 25° C. was measured using a pH meter (F-51 manufactured by Horiba, Ltd.).

[0353] (Measurement of combing strength after treatment with conditioner + 2 shampooing)

[0354] (1) Mix 7 mL of "Kao Foam Hair Bleach L" (Part 1) and 15 mL of "Kao Foam Hair Dye D" (Part 2) manufactured by Kao Corporation and apply to a 20 cm long, 30 g mass Japanese hair tress. After standing for 20 minutes, rinse thoroughly with warm water at 35 to 40°C (bleaching treatment). Repeat this bleaching treatment 4 times to prepare a damaged hair tress for evaluation. Wash the hair tress with a normal shampoo of the following composition and make it contain 15 g ± 0.5 g of water.

[0355] (2) Apply 1.5 mL of the conditioner of each example to the above-mentioned hydrated hair bundle, apply it by hand and leave it for 30 seconds, then rinse it with warm water at 35-40°C for 15 seconds. Then, rub the front and back of the hair bundle 20 times each within 30 seconds with 1 mL of the above-mentioned ordinary shampoo, and rinse it for 15 seconds.

[0356] (3) Apply 1 mL of the following ordinary conditioner, rub it with your hands for 30 seconds, and rinse for 15 seconds. Again, use 1 mL of the above ordinary shampoo to rub the front and back of the hair 20 times each within 30 seconds, and rinse for 15 seconds.

[0357] (4) After combing the hair bundle with a brush to completely untangle the knot, adjust the water content of the hair bundle after rinsing to 15g±0.5g. Place in a combing force measuring device ("KOT-0303" manufactured by Utsunomiya Seiki Co., Ltd.), let two brushes (Kao Lunette) pass through the uppermost part of the hair bundle, comb at a constant speed (60rpm), and measure the load (g) applied when the comb passes through the hair tip. Combing is performed 50 times, and the average value of the combing load at a total of 50 points is defined as the value of "combing force immediately after treatment". The smaller the combing force value, the better the result. The combing load of the damaged hair bundle (water content 15g±0.5g) that was not subjected to the above-mentioned (2) treatment was 2055g. If the combing force is 1900g or less, it is judged that the shampoo resistance is good.

[0358] [Composition of regular shampoo] * The amount of ingredients is the amount of active ingredients.

[0359]

[0360] (*1) 42.0% by mass based on "Emal E-27C" manufactured by Kao Corporation (active ingredient content 27% by mass)

[0361] (*2) Aminon C-11S (manufactured by Kao Corporation), active ingredient content 100% by mass

[0366] (*5) "PURAC ULTRAPURE90" manufactured by PURAC Thailand Ltd., active ingredient content 90% by mass

[0367] (Measurement of combing strength after treatment with conditioner + 4 shampooing)

[0368] After performing (1) to (2) in the above-mentioned "Measurement of combing force after treatment with conditioner + 2 times of shampooing", (3) was performed 3 times, and then (4) was performed to measure the combing force.

[0369] (Emulsified state of conditioner after 2 days)

[0370] 1 g of the conditioner of each example was dropped onto a black plastic plate 2 days after formulation, and the appearance when traced 10 times with fingers and the touch when crushed with fingers were evaluated according to the following criteria.

[0371] A: Agglomerated particles cannot be identified, and the texture is smooth when crushed with fingers.

[0372] B: Agglomerated particles cannot be identified, but feel rough when crushed with fingers

[0373] C: Agglomerated particles can be identified and feel rough when crushed with fingers

[0374] D: Detached

[0375] (Wetness resistance of treated hair)

[0376] 7 mL of "Kao Bubble Hair Bleach L" (Part 1) and 15 mL of "Kao Bubble Hair Dye D" (Part 2) manufactured by Kao Corporation were mixed and applied to a 30 cm long, 20 g mass Japanese hair tress. After standing for 20 minutes, the tress was thoroughly rinsed with warm water at 35 to 40°C (bleaching treatment). This bleaching treatment was repeated 4 times to prepare a damaged hair tress for evaluation.

[0377] After washing the hair bundle with the above-mentioned ordinary shampoo, 1 mL of the conditioner of each example was applied for 30 seconds and left in this state for 1 minute, then rinsed with running water at 35 to 40° C. for 30 seconds and dried with a hair dryer until completely dry.

[0378] The dried hair was straightened 10 times with a hair straightener ("AHI-938" manufactured by Miki Electric Industry Co., Ltd.) set at 160°C while being combed, and a photo of the hair bundle just after being straightened was taken. Then, the straightened hair was hung and left to stand for 30 minutes in a high humidity environment of 35°C and 80%RH, and the photo was taken again. In the two photos, the hair bundle width was measured at a position 23.5 cm from the root of the hair bundle, and the change in the hair bundle width just after straightening and after being stored under high humidity was calculated according to the following formula.

[0379] Hair strand width change value = (hair strand width after storage at high humidity) / (hair strand width immediately after straightening)

[0380] When the value is 1.3 or more, the appearance also looks broad, and therefore, it is judged that the moisture resistance is low.

[0381] Examples 1 to 13, Comparative Examples 1 to 11 (Preparation and Evaluation of Hair Conditioners)

[0382] A hair conditioner was prepared by the following procedure using the respective components in the amounts described in the table.

[0383] An anionic polymer (component (B1) or component (B1) and component (B2)) pre-dispersed in dipropylene glycol was added to a 500 mL beaker containing water, and heated and stirred at 56° C. After confirming that the anionic polymer was completely dissolved, in Examples 2 to 9 and 12 to 13, a nonionic polymer (G) was further added and completely dissolved.

[0384] Next, add 90% lactic acid (57% of the total amount) and a cationic polymer (component (A) or component (A')). Furthermore, add an oily phase obtained by mixing (E) a cationic surfactant, (F) a higher alcohol, the remaining dipropylene glycol, and benzyl alcohol in advance and dissolving them at 85°C, and stir at 56°C for 10 minutes. After stirring for 10 minutes, stop heating and start air cooling. After air cooling, add the silicone (component (C) and component (D)) listed in the table and the remaining 90% lactic acid, and cool while stirring until the liquid temperature becomes 40°C or less to obtain 500 mL of a conditioner.
