Description

Technical Field

[0001] The present invention relates to a cosmetic composition. Background Art

[0002] It is known that hair is damaged by external factors in daily life, chemical treatments such as perming or hair dyeing, etc., resulting in difficulty in handling. In order to eliminate this state, gloss or smoothness is given to hair by conditioners or styling agents. However, these effects mostly disappear due to physical forces received in daily life such as a single shampoo, and friction between hair and pillows during sleep, so the industry needs products with continuous effects. Furthermore, it is expected that good touch can be given to hair in all scenes of daily life, i.e., dry state and wet state. For example, Patent Document 1 (Japanese Patent Table 2015-515981 Gazette) discloses that the following composition is more useful as a hair care product for treating split ends of hair, and the above-mentioned composition comprises a continuous aqueous phase and a discontinuous phase containing a plasticized MQ type silicone resin and / or its derivatives and / or a plasticized MT type silicone resin and / or its derivatives, and the discontinuous phase is emulsified in an aqueous phase.

[0003] Patent document 2 (Japanese Patent Publication No. 2016-503433) discloses a composition comprising a silicone resin and a silicone rubber, wherein a mixture of the silicone resin and the silicone rubber has a softening point exceeding 50°C and an elastic modulus of 106 Pa or less at ambient temperature, and discloses that when a compound comprising the composition is applied to hair, a smooth touch and strong gloss are imparted.

[0004] Incidentally, in cosmetic compositions containing colorants such as pigments, in order to achieve the goals of improving durability after application, suppressing color transfer of colorants, etc., research is being conducted on the use of film-forming agents. For example, Patent Document 3 (Japanese Patent Publication No. 2000-501074) discloses a cosmetic composition comprising: a mixture obtained by mixing an organosiloxane resin fluid and an organopolysiloxane polymer at a specific ratio, and a volatile carrier, and discloses the formation of a durable film that is resistant to color transfer when in contact with objects such as clothes and towels.

[0005] In addition, as one of the hair dyeing techniques, there is a known temporary hair dye technique in which a coating containing a pigment or the like is formed on the hair to dye the hair. With this hair dye, the hair is less damaged and the hair can be dyed easily, but there are also cases where the color is easily bleached by shampooing, or the friction resistance of the dyed hair is low, so the colored coating is peeled off when rubbed and adheres to clothes or pillows for a second time.

[0006] In this regard, for example, patent document 4 (Japanese Patent Gazette No. 10-265354) discloses a hair dye that is easy to apply, does not produce secondary adhesion after application, and has good color durability; the hair dye is characterized in that it contains: volatile oil, silicone resin dissolved in the volatile oil, hydrophobic polymers such as high molecular weight organopolysiloxane, powder, and non-volatile oil that is compatible with the volatile oil, and at least a portion of the powder is a coloring pigment.

[0031] As used herein, “film formation” means that a film remains on a substrate to which the composition is applied.

[0032] As used in this specification, "volatile" means having a boiling point of 260°C or less under normal pressure.

[0033] [Cosmetic composition]

[0034] The cosmetic composition of the present invention contains the following components (A) to (C),

[0035] (A) an organic silicon film-forming agent,

[0036] (B) a high molecular weight organopolysiloxane,

[0037] (C) An organopolysiloxane other than the component (A) and the component (B) having a polyalkylene oxide moiety and a cationic group.

[0038] The cosmetic composition of the present invention has the above-mentioned structure, and when applied to keratin substances such as skin and hair, it can provide a good touch in both dry and wet states, has excellent durability against friction, and has excellent persistence of these effects after washing.

[0039] Patent Document 1 verifies the sustainability of the cycle of washing, drying, and perming, but does not mention the improvement of the feel of hair in a wet state (for example, when washing hair) or the durability against friction with pillows and the like.

[0040] Patent Document 2 does not mention the improvement of the feel of hair in a wet state, the durability against friction, and the durability of these effects against washing and friction.

[0041] Patent Document 3 verifies the color transfer resistance, but does not mention the effect on the durability after washing or the touch in dry and wet states.

[0042] Furthermore, although Patent Document 4 mentions the secondary adhesion, color durability and feel of the hair dye, it does not mention the improvement of the feel of the hair in a wet state.

[0043] Thus, among the existing cosmetic compositions, there is no cosmetic composition that, when applied to keratin substances such as skin and hair, can provide a good touch in both dry and wet states, has excellent durability against friction, and has excellent persistence of these effects after washing.

[0044] The present invention aims to provide a cosmetic composition which, when applied to keratinous materials such as skin and hair, imparts a good touch in both dry and wet states, is excellent in durability against friction, and has excellent persistence of these effects after washing.

[0045] In order to solve these problems, the film formed on the keratin material is considered to require the following properties.

[0046] In order to give a good touch to keratin substances, the coating surface is believed to be smooth, and in order to obtain durability against friction, adhesion to keratin substances and coating strength that can withstand the physical force during friction are believed to be required. Furthermore, in order to obtain durability against washing, hydrophobicity is believed to be required and coating strength that can withstand the physical force during washing is required.

[0047] That is, in order to solve the problem of the present invention, it is considered that the film formed on the keratin material must be hydrophobic and must simultaneously satisfy multiple different properties of surface smoothness, high film strength, and high adhesion to the keratin material. Therefore, another aspect of the problem of the present invention is to form a film on the keratin material that is hydrophobic and simultaneously satisfies the requirements of surface smoothness, high film strength, and high adhesion to the keratin material.

[0048] The inventors of the present invention have found that a cosmetic composition containing a silicone film-forming agent, a high molecular weight organopolysiloxane, and an organopolysiloxane having a polyalkylene oxide moiety and a cationic group can solve the above-mentioned problems, thereby completing the present invention.

[0049] According to the present invention, a cosmetic composition can be provided, which, when applied to keratin substances such as skin or hair, can impart a good touch in both dry and wet states, has excellent durability to friction, and these effects are sustained after washing. When the cosmetic composition is used as a hair dye composition, a good touch can be imparted to hair in all states of dry and wet states, and the peeling of the coloring film caused by friction after dyeing the hair is also less, and secondary adhesion on clothes or pillows can be suppressed. In addition, there is less fading after shampooing, and the color persistence is good. Furthermore, a good touch can be sustained after shampooing, and the secondary adhesion suppression effect is also maintained.

[0050] The reason why the cosmetic composition of the present invention exhibits the above-mentioned effects has not yet been determined, but is presumed to be as follows.

[0051] The cosmetic composition of the present invention comprising the component (A), the component (B) and the component (C) can form a hydrophobic film by being applied to the surface of a keratin substance.

[0052] It is considered that the cosmetic composition containing component (A), component (B) and component (C) is preferably temporarily dissolved or dispersed before use and then applied to the surface of the keratin substance, so that the components undergo phase separation over time, and a hydrophobic film with a multilayer structure in which the components show a concentration distribution in the thickness direction can be formed on the surface of the keratin substance.

[0053] As a specific multilayer structure, it is a multilayer structure having at least two layers, that is, a layer containing component (B) on the outermost surface of the coating and a layer containing component (C) on the interface side with the keratin substance; preferably, it is a multilayer structure having at least three layers, that is, a layer containing component (A) is further provided between the layer containing component (B) and the layer containing component (C).

[0054] The layers described here may not be clearly separated from each other. In this specification, the so-called "layer" in the multilayer structure is referred to as a "layer" if there is a region having a concentration distribution in the thickness direction of the coating and any one of the components (A) to (C) is concentrated as the main component. For example, "a layer containing component (B) on the outermost surface of the coating" means a region having component (B) as the main component concentrated on the outermost surface side relative to the thickness direction of the coating. The main component mentioned here refers to the component with the highest concentration among components (A) to (C). It is also believed that between the layers, the polymer chains of the components mainly contained in the adjacent layers are allowed to invade each other, thereby forming an interface phase having a thickness and a continuously changing concentration.

[0055] It is believed that when the cosmetic composition of the present invention is applied to the surface of a keratin substance, the component (B) is concentrated on the outermost surface of the film formed, exerting an effect of imparting a good touch to the surface of the keratin substance, and furthermore, also fulfilling a function as a surface protective layer. In addition, it is believed that the component (C) is concentrated on the keratin substance side, and it is believed that the film formed is firmly adhered to the surface of the keratin substance, exerting an effect of preventing the film from peeling off.

[0056] On the other hand, component (A) is a hydrophobic film-forming agent, and is present in the layer containing component (B) or component (C) in the formed film, or is concentrated in the middle part of the layer containing component (B) and component (C) in the formed film. It is believed that it maintains the strength and durability of the entire formed film, and through the synergistic effect with component (B) and component (C), it also exerts an effect of improving the durability of various properties imparted to keratin substances.

[0057] Furthermore, when a functional powder described below is blended in the cosmetic composition, the functional powder can be retained in the film to enhance various functions and their durability.

[0058] It is considered that due to the above-mentioned mechanism of action, for example, when the cosmetic composition is a hair cosmetic composition, due to the synergistic effect of the film-forming property of the component (A), the feel-imparting effect and surface protective performance of the component (B), and the peeling prevention property of the film of the component (C), when applied to the hair, a good feel can be imparted to the hair in both dry and wet states, and durability against friction and persistence of these effects after washing can be obtained.

[0059] In addition, it is believed that when the cosmetic composition is a hair dye composition such as a temporary hair dye composition or a semi-permanent hair dye composition, it can be a hair dye composition that can give a good touch to hair in all states of a dry state and a wet state after dyeing, and the peeling of the colored film caused by friction after dyeing is also less. In addition, it is believed that there is less bleaching after shampooing, the color persistence is good, and then, a good touch can be continued after shampooing, and the secondary adhesion inhibition effect can also be maintained.

[0060] It should be noted that the mechanism of action of the present invention is not limited to the above content.

[0061] Hereinafter, each component contained in the cosmetic composition of the present invention will be described.

[0312] [Method of forming a coating and coating]

[0313] The present invention provides a method for forming a film on the surface of a keratin substance (hereinafter, also referred to as "the method of the present invention"), which comprises the following steps (I) to (III) in order.

[0314] Step (I): a step of temporarily dissolving or dispersing a composition containing the following components (A) to (C),

[0315] (A) an organic silicon film-forming agent,

[0316] (B) a high molecular weight organopolysiloxane,

[0317] (C) an organopolysiloxane other than the component (A) and the component (B) having a polyalkylene oxide moiety and a cationic group,

[0318] Step (II): a step of applying the composition prepared in step (I) to the surface of a keratinous substance,

[0319] Step (III): a step of drying the composition applied to the surface of the keratinous substance in step (II).

[0320] In addition, the present invention provides a multilayer structured coating (hereinafter also referred to as "the coating of the present invention"), which covers the surface of a keratin substance, the coating containing the following components (A) to (C), and having a layer containing component (B) on the outermost surface of the coating, and having a layer containing component (C) on the interface side with the keratin substance.

[0321] (A) an organic silicon film-forming agent,

[0322] (B) a high molecular weight organopolysiloxane,

[0323] (C) An organopolysiloxane other than the component (A) and the component (B) having a polyalkylene oxide moiety and a cationic group.

[0324] The film of the present invention can be formed by applying a composition containing the above-mentioned components (A) to (C) to the surface of a keratinous substance by spreading.

[0325] In order to satisfy multiple properties at the same time, it is difficult to achieve this goal by using a uniform coating. The industry has also developed a method of obtaining a coating that satisfies multiple properties at the same time by stacking layers with different properties, but the method of repeated application is more complicated. It is preferred to form a coating with a multi-layer structure by a single application process. According to the coating formation method of the present invention, in step (I), the composition containing the above-mentioned components (A) to (C) is temporarily dissolved or dispersed before use, and then in step (II), the composition is applied to the surface of the keratin material, and a drying operation is performed in step (III), whereby the components undergo phase separation over time, and it is believed that the above-mentioned coating with a multi-layer structure can be spontaneously formed.

[0326] Regarding the method of temporarily dissolving or dispersing the composition containing components (A) to (C) in step (I), any thermodynamic method such as heating can be used; physical methods such as mechanically applying shear stress; chemical methods such as adding a solvent that is compatible or dispersible with components (A) to (C), etc. From the perspective of user convenience, it is preferable to pre-dissolve or disperse uniformly by physical methods such as stirring and shaking. In addition, in this case, from the perspective of easy use of physical methods such as stirring and shaking, it is preferred to pre-add a solvent (component (E)) that is compatible or dispersible with components (A) to (C) to the composition.

[0327] From the viewpoint of promoting film formation, the solvent added to the composition is preferably applied to the surface of the keratin substance in step (II) and then dried in step (III) to be removed from the film. For example, the following method can be cited: in step (I), the composition is prepared using the volatile solvent as a solvent, and in step (II), the composition is applied to the surface of the keratin substance and then dried in step (III) to evaporate and remove the volatile solvent from the film.

[0328] The coating structure formed by the method of the present invention is preferably a multilayer structure formed on the surface of the keratin material and having a concentration distribution of each component in the thickness direction, specifically a multilayer structure having at least two layers, that is, a layer containing component (B) on the outermost surface of the coating, and a layer containing component (C) on the interface side with the keratin material; from the viewpoint of maintaining the strength and durability of the entire formed coating, it is preferably a multilayer structure having at least three layers, that is, a layer containing component (A) is further provided between the layer containing component (B) and the layer containing component (C).

[0329] It is believed that when the cosmetic composition of the present invention is applied to the surface of a keratinous substance, the component (B) is concentrated on the outermost surface of the film formed, exerting an effect of imparting a good touch to the surface of the keratinous substance in both a dry state and a wet state, and further assuming a function as a surface protective layer. In addition, it is believed that the component (C) is concentrated on the keratinous substance side, and it is believed that the film formed is firmly adhered to the surface of the keratinous substance, exerting an effect of preventing the film from peeling off.

[0330] On the other hand, component (A) is a hydrophobic film-forming agent, which is present in the layer containing component (B) or component (C), or is concentrated in the middle part of the layer containing component (B) and component (C) in the formed film. It is believed that it maintains the strength and durability of the entire formed film, and through the synergistic effect with component (B) and component (C), it also exerts an effect of improving the durability of various properties imparted to keratin substances.

[0331] The components (A), (B), and (C) constituting the film and their suitable embodiments are the same as those described in the above-mentioned cosmetic composition.

[0332] From the viewpoint of forming a good multilayer structure coating, as component (A), trimethylsiloxysilicic acid is preferably contained, and trimethylsiloxysilicic acid is more preferred.

[0553] Hereinafter, the present invention will be described using examples, but the present invention is not limited to the scope of the examples. It should be noted that in the present examples, various measurements and evaluations were performed using the following methods.

[0554] <Preparation of evaluation hair bundle>

[0555] A human white hair (100%) hair bundle (Beaulax, length 10 cm, mass 1 g) was washed with a sample shampoo of the following composition, rinsed with 40°C warm water and dried thoroughly to prepare an evaluation hair bundle.

[0556] (Sample Shampoo Composition)

[0557]

[0558] *1: 57.4% by mass based on Emal 227 (manufactured by Kao Corporation, active ingredient 27% by mass),

[0559] *2: AMINON L-02 (manufactured by Kao Corporation)

[0560] <Dry touch>

[0561] The hair cosmetic composition of each example was uniformly mixed, and 0.3 g was applied to the above-mentioned hair bundle for evaluation. Then, using a hair dryer ("P2-D250" manufactured by Hitachi, Ltd., set to HIGH), warm air was blown for 30 seconds from a position 18 cm away from the hair bundle to dry the hair bundle. Thereafter, while combing, warm air was blown for 30 seconds to dry the hair bundle to perform hair treatment. The touch of the treated hair bundle was sensory evaluated by a professional sensory inspector according to the following criteria, and the total score of N=3 was calculated. 6 points or more was an acceptable touch, 9 points or more was a good touch, and 12 points or more was a more good touch.

[0562] 5: No stickiness at all

[0563] 4: Almost no stickiness

[0564] 3: Feels slightly sticky

[0565] 2: Feeling sticky

[0566] 1: Feeling very sticky

[0567] <The feeling when washing hair>

[0568] The hair cosmetic composition of each example was uniformly mixed, and 0.3 g was applied to the above-mentioned hair bundle for evaluation. Then, a hair dryer ("P2-D250" manufactured by Hitachi, Ltd., set to HIGH) was used to blow warm air for 30 seconds from a position 18 cm away from the hair bundle to dry the hair bundle. Thereafter, warm air was blown for 30 seconds while combing the hair bundle to dry the hair bundle for hair treatment. The treated hair bundle was washed with the sample shampoo of the above composition, and then rinsed with warm water at 40°C. The touch of the hair bundle at this time was sensory evaluated by a professional sensory inspector according to the following criteria. The touch was good when it was 2 or more, and the touch was more good when it was 3.

[0569] 3: The hair bundles are easy to spread out and feel light to the touch

[0570] 2: When you comb the hair with your fingers, it will spread out and feel lighter.

[0571] 1: The hair is hard to spread out and feels heavy to the touch

[0572] <How hair feels when dry after 7 shampooing>

[0573] The hair bundles treated in the same manner as in the "Dry Feel" were washed with the sample shampoo of the above composition, rinsed with 40°C warm water and dried, and this process was repeated 7 times in total. The hair bundles after 7 washes and drying were evaluated for feel in the same manner as above.

[0574] <Shampooing resistance (how easy it is to fade after 7 washes)>

[0575] To visually confirm the formed coating, 0.15 g of a 15 mass % carbon black dispersion was added to 6 g of the hair cosmetic composition of Examples 1 to 20 and Comparative Example 1, and the mixture was uniformly mixed to prepare an evaluation composition.

[0576] The hair cosmetic compositions of Examples 21 to 25 containing a pigment as the component (D) were uniformly mixed with the respective components described in the table to prepare hair cosmetic compositions for evaluation.

[0577] 0.3 g of the above composition was applied to the above-mentioned hair bundle for evaluation, and then warm air was blown for 30 seconds from a position 18 cm away from the hair bundle using a hair dryer ("P2-D250" manufactured by Hitachi, Ltd., set to HIGH) to dry the hair bundle. Thereafter, warm air was blown for 30 seconds while combing the hair to dry the hair bundle for hair treatment.

[0578] A colorimeter (CR-400, manufactured by Konica Minolta, Inc.) was used to analyze the color using the CIE color system (L * ,a * ,b *) After measuring the treated hair bundle, the hair was washed with the sample shampoo of the above composition, rinsed with warm water at 40°C and dried, and this process was repeated 7 times in total. The hair bundle after 7 washes and drying was measured with a colorimeter in the same way, and the color difference (ΔE) from the hair bundle before washing was calculated according to the following formula * ). * ,a * ,b * The measurement was performed at 6 different locations on the hair bundle (2 locations in the center of each area after the hair bundle was divided into 3 equal parts in the length direction), and the average value was calculated.

[0579]

[0580] L0 * 、a0 * 、b0 * : The measured value of the hair bundle after treatment (before shampooing),

[0581] L1 * 、a1 * 、b1 * : Measured value of hair bundle after 7 shampooings.

[0582] If ΔE * <15, the treated hair is judged to have good shampoo resistance and excellent color durability. * <10, it is even better. If ΔE * <5 is particularly good.

[0583] <Abrasion resistance (degree of color migration)>

[0584] To visually confirm the formed coating, 0.15 g of a 15 mass % carbon black dispersion was added to 6 g of the hair cosmetic composition of Examples 1 to 20 and Comparative Example 1, and the mixture was uniformly mixed to prepare an evaluation composition.

[0585] The hair cosmetic compositions of Examples 21 to 25 containing a pigment as the component (D) were uniformly mixed with the respective components described in the table to prepare hair cosmetic compositions for evaluation.

[0586] 0.3 g of the above composition was applied to the above-mentioned hair bundle for evaluation, and then warm air was blown for 30 seconds from a position 18 cm away from the hair bundle using a hair dryer ("P2-D250" manufactured by Hitachi, Ltd., set to HIGH) to dry the hair bundle. Thereafter, warm air was blown for 30 seconds while combing the hair to dry the hair bundle for hair treatment.

[0587] Next, a circular qualitative filter paper No. 2 (Φ150 mm, manufactured by ADVANTEC) was folded in half and the treated hair bundle was sandwiched therein. A weight of 600 g was placed on the paper and the hair bundle was pulled out for about 1 second in this state. This operation was performed 3 times in total.

[0588] Scan the used filter paper, use the image processing software "Image J", find the adhesion area of ​​carbon black or pigment, calculate the adhesion ratio {(adhesion area) ÷ (filter paper area) × 100} (%) and show it in the table. The lower the adhesion ratio value, the less color shift on the filter paper, and the better the friction resistance. In addition, the adhesion ratio is good when it is 1.70 (%) or less, better when it is 0.95 (%) or less, and particularly good when it is 0.60 (%) or less.

[0589] <Friction resistance after 7 shampooings>

[0590] The hair bundles treated in the same manner as in the above "Friction Resistance (Degree of Color Migration)" were washed using the sample shampoo of the above composition, rinsed with 40°C warm water and dried, and this process was repeated 7 times in total. The friction resistance of the hair bundles after 7 washes and drying was evaluated by the same method as above.

[0591] Examples 1 to 20, Comparative Example 1 (Preparation and Evaluation of Hair Cosmetic Compositions)

[0592] The components shown in Tables 1 to 6 were blended at the blending ratios described in the respective tables and mixed until uniform to prepare hair cosmetic compositions. Various evaluations were performed using the obtained hair cosmetic compositions by the above-mentioned methods. The results are shown in Tables 1 to 6.

[0593] In addition, the compounding amounts (mass %) described in the table are all amounts of effective ingredients.

[0622] *10: X-25-9074, manufactured by Shin-Etsu Chemical Co., Ltd., high molecular weight dimethyl polysiloxane, viscosity at 25°C: 30 million mm 2 / s,

[0623] *11: X-21-5666, manufactured by Shin-Etsu Chemical Co., Ltd., a solution of high molecular weight polydimethylsiloxane (30% by mass) in cyclopentasiloxane, with a viscosity of 3.5 million mm at 25°C 2 / s),

[0626] *14: MARUKASOL R, manufactured by Maruzen Petrochemical Co., Ltd., isododecane.

[0627] It should be noted that regarding the degree of polymerization (P) of the above-mentioned components *7 to 11, the molecular weight (M) was calculated from the viscosity (η) based on the above-mentioned formula (4), and the degree of polymerization (P) was calculated from the following formula (5) because the molecular weight of the basic unit of dimethylpolysiloxane is 74.

[0628] P=M / 74 (5)

[0629] According to Tables 1 to 6, when the cosmetic composition of the present invention is applied to keratin substances, a good touch feeling can be imparted in both dry and wet states, and durability against friction is excellent, and these effects persist even after 7 washes.

[0630] <Confirmation of film formation status>

[0631] Figure 1The elastic modulus analysis image (measurement area 5 μm×5 μm) of the cross section of hair treated with the hair cosmetic composition of Example 1 obtained by the measurement method described later and the image obtained by enlarging the coating portion. In the elastic modulus analysis image, a dark portion indicates a low elastic modulus, and a bright portion indicates a high elastic modulus.

[0632] The film formed by the hair cosmetic composition of Example 1 is composed of trimethylsiloxysilicate as component (A), high molecular weight organopolysiloxane as component (B), and PEG / aminodimethicone copolymer as component (C).

[0633] according to Figure 1 It was confirmed that a region with a high elastic modulus appeared in the middle of the film in the elastic modulus analysis image, and that phase separation occurred in the mixed system of the above components (A) to (C) to form a multilayer structure.

[0634] Since the elastic modulus of component (A) of the coating when dried is higher than those of components (B) and (C), it is estimated that component (A) is concentrated in the middle portion of the coating.

[0635] On the other hand, since the hair cosmetic composition of Example 1 exhibited a good touch in both the dry state and the wet state, it is presumed that the component (B) having surface smoothness is concentrated on the outermost surface of the coating. In addition, since the hair cosmetic composition of Example 1 exhibited durability against friction and durability against shampooing, it is presumed that the component (C) having high adhesion to keratin substances is concentrated on the keratin substance side.

[0636] In addition, since the elastic modulus of the middle part of the film in the elastic modulus analysis image changes slowly in the thickness direction of the film, it is estimated that the layers containing each component are not clearly separated, and polymer chains of different components penetrate each other between the layers, thereby forming an interface phase with thickness and continuously changing concentration.

[0637] Thus, it was confirmed that, after the hair cosmetic composition of Example 1 was applied to the surface of a keratin substance, components (A) to (C) were phase-separated to form a multilayer structure on the surface of the keratin substance.

[0638] [Preparation of measurement samples]

[0639] The hair cosmetic composition of Example 1 was uniformly mixed, and 0.3 g was applied to the above-mentioned hair bundle for evaluation, followed by drying with a hair dryer to perform hair treatment. The treated hair was immersed in a liquid photocurable resin composition (ARONIX LCR D-800, manufactured by Toagosei Co., Ltd.), and irradiated with ultraviolet rays for 1 minute (LED fiber light source (LUXSPOT II), manufactured by JEOL), thereby embedding the treated hair one by one in the resin. The resin embedding the treated hair was fixed to a Φ12 mm AFM specimen base (AFM Specimen disc, manufactured by TED PELLA) using an adhesive. After exposing the measurement specimen surface using a single-edged trimming razor (T568, manufactured by GEM), the measurement specimen surface was trimmed using an ultrathin microtome (EM UC7i, manufactured by Hitachi High Tech).

[0640] [Measurement method]

[0641] The measurement was performed using an atomic force microscope (MFP-3D, manufactured by Oxford Instruments) in AMFM mode. The cantilever used was AC-160TS (spring constant 29.4 N / m, manufactured by Olympus). The measurement environment was a temperature of 25.5° C. and a humidity of 34 to 39%.

[0642] Examples 21 to 24 (Preparation and evaluation of hair dye composition)

[0643] The components shown in Table 7 were mixed at the mixing ratios described in the table and mixed until uniform to prepare a hair dye composition. Various evaluations were performed using the obtained hair dye composition by the above-mentioned methods. The results are shown in Table 7.

[0644] In addition, the compounding amounts (mass %) described in the table are all amounts of effective ingredients.

[0651] According to Table 7, when the hair dye composition of the present invention is applied to hair, a good touch is imparted in both dry and wet states, and durability against friction is excellent, and these effects persist even after 7 washes.

[0652] Example 25 (Preparation and evaluation of hair dye composition)

[0653] The components shown in Table 8 were blended at the blending ratios described in the table and mixed until uniform to prepare hair dye compositions. The obtained hair dye compositions were used to evaluate friction resistance, dry touch, touch during shampooing, and shampoo resistance by the above-mentioned methods.

[0654] Furthermore, in order to confirm the durability of the effect of the present composition on hair, the following shampoo resistance (degree of fading after 28 shampooings), friction resistance after 28 shampooings, and touch in a dry state after 28 shampooings were evaluated. The results are shown in Table 8.

[0655] In addition, the compounding amounts (mass %) described in the table are all amounts of effective ingredients.

[0656] <Shampooing resistance (degree of fading after 28 washes)>

[0657] The hair bundles treated in the same manner as in the above-mentioned "shampooing resistance (degree of fading after 7 shampooings)" were analyzed using the CIE colorimetric system (L * ,a * ,b * ) was measured, and then the hair was washed with the sample shampoo of the above composition, rinsed with warm water at 40°C and dried, and this process was repeated 28 times in total. Similarly, the colorimeter was used to measure the hair bundles after 28 washes and drying, and the color difference (ΔE * ).

[0658] <Friction resistance after 28 shampooings>

[0659] The hair bundles treated in the same manner as in the above "Friction Resistance (Degree of Color Migration)" were washed using the sample shampoo of the above composition, rinsed with 40°C warm water and dried, and this process was repeated 28 times in total. The friction resistance of the hair bundles after 28 washes and drying was evaluated in the same manner as above.

[0660] <How hair feels when dry after 28 shampooing>

[0661] The hair bundles treated in the same manner as in the "Feel in Dry State" were washed with the sample shampoo of the above composition, rinsed with 40°C warm water and dried, and this process was repeated 28 times in total. The hair bundles after 28 washes and drying were evaluated for feel in the same manner as above.

[0662] [Table 8]

[0663] Table 8

[0664]

[0665] According to Table 8, when the hair dye composition of the present invention is applied to hair, a good touch can be given in both dry and wet states, and the durability to friction is excellent, and these effects continue after 28 washes. Therefore, it is believed that when washing hair once a day, the hair dyeing effect continues for about 1 month.

[0666] Industrial Applicability

[0667] According to the present invention, a cosmetic composition can be provided, which, when applied to keratin substances such as skin or hair, can impart a good touch in both dry and wet states, has excellent durability to friction, and these effects persist even after washing.
