Description

Technical Field

[0001] The invention relates to a hair treating agent or a fiber treating agent for head ornaments such as wigs and hair extensions. Background Art

[0002] In recent years, in the field of cosmetics, a technique for forming a hydrophobic film has been studied as a method for imparting various properties such as gloss and good touch to keratin substances such as skin and hair.

[0003] As a polymer for forming a hydrophobic film, there is a known technique for using a film-forming polymer of the silicone type. For example, Japanese Patent Publication No. 9-501934 (Patent Document 1) discloses a topical personal care composition for a styling composition, etc., which contains the following substances: a polysiloxane grafted adhesive polymer; a volatile non-water-soluble solvent for the polysiloxane grafted polymer; a non-volatile drying aid for the polysiloxane grafted polymer, which is soluble in the solvent at 45°C and non-water-soluble at 25°C, and is a component selected from silicone fluids and waxes, silanes, silicone resins and mixtures thereof having 1 to 100 siloxy units; and the weight ratio of the polysiloxane grafted adhesive polymer to the drying aid is below a specified value. In addition, the following is disclosed: the composition does not substantially lose any hair retention performance when completely dried, and can reduce the drying time of the styling composition.

[0004] In addition, since the properties imparted to keratin substances by cosmetics or the properties imparted to fibers for hair accessories by fiber treatment agents are often lost due to friction generated during daily activities or after washing, cosmetics or fiber treatment agents with excellent durability of effect are sought. In general, the film formed by silicone-based film-forming polymers is hard and brittle, so research is being conducted to improve the feel and durability.

[0005] For example, Japanese Patent Laid-Open No. 2018-2643 and Japanese Patent Laid-Open No. 2021-134166 (Patent Documents 2 and 3) disclose a cosmetic which has no stickiness when applied, good ductility, excellent touch during use, good water resistance, good adhesion to the skin, and thus excellent makeup durability and can prevent adhesion to clothes, etc. (secondary adhesion). The cosmetic is characterized in that the following silicone resin is formulated: a structural unit (R 1 3SiO 1 / 2 )、(R 2 2SiO 2 / 2 )、(R 3 SiO 3 / 2 ), and (SiO 4 / 2 )(where R 1 , R2 and R 3 The alkyl group is independently selected from an alkyl group having 1 to 8 carbon atoms, an aryl group having 6 to 12 carbon atoms, and a fluorine-substituted alkyl group having 1 to 8 carbon atoms), and the ratio and weight average molecular weight of each structural unit are within a specified range.

[0006] Japanese Patent Publication No. 2019-513712 (Patent Document 4) discloses a cosmetic composition that can form a multilayer structure after being applied to a keratin substance, the cosmetic composition comprising, in a predetermined weight ratio: at least one silicone and / or hydrocarbon-containing film-forming agent having at least one glass transition temperature of less than 60° C., and one or more polysilicone compounds in an amount sufficient to achieve a viscosity of about 1,000 cSt to 22,000,000 cSt, the composition having the following properties: improved cosmetic properties upon application, particularly good durability, touch, radiance, brightness, and / or matte feeling.

[0007] Japanese Patent Publication No. 2021-526180 (Patent Document 5) discloses the following: A phenyl silicone resin represented by a prescribed composition formula and having a weight average molecular weight and a refractive index of the coating within a prescribed range is soluble in organic oily components such as silicone oil and hydrocarbon oil, thereby obtaining a uniform continuous coating, and the coating is non-sticky and non-brittle, and has good compatibility with ultraviolet absorbers. In addition, it is recorded that: cosmetics formulated with the phenyl silicone resin have a good feel and can prevent adhesion to clothes, etc. (secondary adhesion). Summary of the invention

[0040] The hair treatment agent or fiber treatment agent for hair ornament products of the present invention is the following hair treatment agent or fiber treatment agent for hair ornament products (I) or (II).

[0041] (I) a hair treatment agent or a fiber treatment agent for hair ornament products, comprising the following components (A) to (C) and having a water content of 10% by mass or less,

[0042] (A) Include (R 1 )3SiO 1 / 2 (R 1 represents a hydrocarbon group or a hydroxyl group having 1 to 12 carbon atoms which may be substituted with fluorine. 1 The M units and SiO 4 / 2 The film-forming polymer of the Q unit shown,

[0049] (D) An organopolysiloxane other than the above-mentioned components (A), (B1), and (C) having a polyalkylene oxide moiety and a cationic group.

[0050] Hereinafter, the hair treatment agent or fiber treatment agent for hair ornament products described in (I) above will also be referred to as the "treatment agent of the first invention" or "treatment agent (I)", the hair treatment agent or fiber treatment agent for hair ornament products described in (II) above will also be referred to as the "treatment agent of the second invention" or "treatment agent (II)", and the hair treatment agents or fiber treatment agents for hair ornament products described in (I) and (II) above will be collectively referred to as the "treatment agent of the present invention".

[0051] The hair treatment agent or fiber treatment agent for hair ornament products (I) of the first invention can provide a good touch to hair or fibers for hair ornament products in both a dry state and a wet state by having the above-mentioned structure, and can show excellent bulkiness and heat setting properties during styling, and can suppress the reduction of the effects such as bulkiness and heat setting properties even after shampooing.

[0052] The hair treatment agent or fiber treatment agent for hair ornament products (II) of the second invention can provide a good touch to hair or fibers for hair ornament products in both a dry state and a wet state by having the above-mentioned structure, and can show excellent heat setting properties and smoothness of hair irons during styling, and can suppress the reduction of heat setting properties even after shampooing.

[0053] The reason why the hair treatment agent or the fiber treatment agent for hair ornament products of the present invention exerts the above-mentioned effects is not determined, but is presumed as follows.

[0054] The hair treatment agent or the fiber treatment agent for hair ornament products (I) of the first invention contains the components (A) and (B), and when applied to hair or hair ornament product fibers, a hydrophobic coating can be formed on the surface of the hair or hair ornament product fibers. It is believed that the film formation effect also improves the ability to impart a fluffy feeling during styling and the heat setting property.

[0055] Since component (A) contains the Q unit, a relatively hard film can be formed. However, since the film is hard and brittle, it is easily peeled off by friction, cleaning, etc., and further, the touch of the hair or the fiber for a hair ornament product may be reduced. However, by making the hair treatment agent or the fiber treatment agent for a hair ornament product of the present invention contain component (B), a softer film than a film containing component (A) alone can be formed, so that the deterioration of the touch of the hair or the fiber for a hair ornament product, and the reduction of the ability to impart a fluffy feeling after shampooing and the heat setting property can be suppressed.

[0056] The inventors believe that the component (C) exists in a large amount on the film surface side (air side) in the formed hydrophobic film, thereby exerting a protective function on the hair surface or the surface of the fiber for hair ornament products, and also contributing to the improvement of the touch, the fluffy feeling during styling, and the durability. In particular, by making the component (C) have a predetermined degree of polymerization, the occurrence of stickiness can be suppressed for the hair or the fiber for hair ornament products in both the dry state and the wet state, and a good touch can be given, and the fluffy feeling during styling can be improved.

[0057] Furthermore, when the water content in the hair treatment agent or the fiber treatment agent for hair ornaments (I) of the first invention is 10% by mass or less, the drying speed is improved, and when the hair treatment agent or the fiber treatment agent for hair ornaments (I) is applied to hair or fibers for hair ornaments, a coating having a phase separation structure in which the component (C) is biased toward the surface side (air side) is efficiently formed, so that the effect of the present invention is more easily exhibited.

[0058] The hair treatment agent or the fiber treatment agent for hair ornament products (II) of the second invention contains the components (A) and (B1), and when applied to the hair or the fibers for hair ornament products, a highly hydrophobic film can be formed on the surface of the hair or the fibers for hair ornament products. It is believed that the heat setting property during styling is improved by the film formation effect.

[0059] Since the component (A) contains the Q unit, a relatively hard film can be formed. However, the film is hard and brittle, so it is easily peeled off by friction, cleaning, etc., and further, the touch of the hair or the fiber for a hair ornament product may be reduced. However, by making the hair treatment agent or the fiber treatment agent for a hair ornament product (II) of the second invention contain the component (B1), a softer film than a film containing only the component (A) can be formed, so it is also possible to suppress the reduction of the touch of the hair or the fiber for a hair ornament product and the reduction of the heat setting property after shampooing.

[0060] The inventors believe that the component (C) undergoes phase separation in the formed hydrophobic film and is present in large amounts on the film surface side (air side). This plays a protective role on the surface of the hair or the fiber for a headdress product, and also contributes to an improvement in the touch and durability. In particular, by making the component (C) have a predetermined degree of polymerization, the occurrence of a sticky feeling can be suppressed for the hair or the fiber for a headdress product in both a dry state and a wet state, and a good touch can be imparted.

[0061] The inventors believe that component (D) has the effect of accelerating the above-mentioned phase separation in the hydrophobic film. Due to this effect, component (C) with high hydrophobicity and low surface tension tends to be biased toward the surface side of the film, and the friction force of the formed film surface is reduced, which can improve the touch, durability, and sliding property of the hair iron.

[0062] In addition, the action mechanism of the present invention is not limited to the above-mentioned action mechanism.

[0063] <Fibers for hair or headwear products>

Among these, preferred are animal hair, human hair, or artificial fibers using polymers or oligomers of proteins or polysaccharides such as keratin, collagen, casein, soybeans, peanuts, corn, waste silk, silk protein (e.g., silk fibroin), etc. as raw materials; more preferred are regenerated protein fibers using proteins such as keratin, collagen, casein, soybean protein, peanut protein, corn protein, silk protein (e.g., silk fibroin) as raw materials; more preferred are regenerated protein fibers such as regenerated collagen fibers using collagen as raw materials and regenerated silk fibers using silk fibroin as raw materials; and further preferred are regenerated collagen fibers.

[0066] Regenerated collagen fibers can be manufactured using known techniques. The composition of the regenerated collagen fibers does not need to be 100% collagen, and may also contain natural polymers, synthetic polymers, additives, etc. for improving quality. Furthermore, the regenerated collagen fibers may also be products that have undergone post-processing or post-treatment. As the form of the regenerated collagen fibers, filaments are preferably used. The filaments are usually taken out from a state wound on a bobbin or taken out from a boxed state. In addition, the filaments obtained in the drying step may also be directly used in the manufacturing step of the regenerated collagen fibers.

[0298] The present invention provides a method for treating hair or fibers for hair ornament products (hereinafter also referred to as "the treatment method of the present invention"), comprising the steps of applying the above-mentioned treatment agent to the hair or fibers for hair ornament products, followed by drying.

[0299] In the case where the treatment agent of the present invention is not a homogeneous system, from the viewpoint of uniform application and improvement of the uniformity of the structure of the formed coating, it is preferred that the treatment agent is temporarily dissolved or dispersed before being applied to the hair or the fibers for hair ornament products. As a method for temporarily dissolving or dispersing the treatment agent, a thermodynamic method such as heating, a physical method such as mechanically applying shear stress, or a chemical method such as adding a solvent having miscibility can be arbitrarily used. From the viewpoint of user convenience, it is preferred that the treatment agent be uniformly dissolved or dispersed in advance by a physical method such as stirring or shaking.

[0300] In the treatment method of the present invention, the amount of the treatment agent applied to the hair or hair ornament fiber is not particularly limited, but is generally in the range of 0.005 to 1 g per 1 g of the hair or hair ornament fiber.

[0301] The treatment method of the present invention comprises the step of applying the treatment agent to the hair or the fiber for a hair ornament product, followed by drying. The treatment agent can be applied to the hair or the fiber for a hair ornament product in any state of a dry state or a wet state, but from the viewpoint of improving the touch of the hair or the fiber for a hair ornament product in a dry state and a wet state, the ability to impart a fluffy feeling during styling, the heat setting property, and the ability to impart a fluffy feeling after shampooing and the continuous effect of the heat setting property, it is preferably applied to the hair or the fiber for a hair ornament product preferably in a dry state, followed by drying, and used without rinsing.

[0302] The treatment agent can be applied by painting, spraying, casting, etc., which can be appropriately selected according to the formulation of the treatment agent. When the treatment agent is applied to hair or fibers for hair accessories, it can be applied by hand or with an application tool such as a brush.

[0303] The hair or the fiber for hair ornament products after applying the above-mentioned treatment agent may be dried naturally or by using a hood dryer, a hair dryer or the like. When using the above-mentioned device, from the viewpoint of suppressing heat damage to the hair or the fiber for hair ornament products, it is preferred to apply a temperature of 40°C to 220°C for drying. More preferably, drying is performed by using a hood dryer or a hair dryer, and the drying temperature is preferably 40°C to 110°C, more preferably 50°C to 90°C. Here, the so-called "temperature" refers to the temperature of the surface of the hair or the fiber for hair ornament products, and can be measured, for example, by an infrared radiation thermometer.

[0304] The drying time is not particularly limited as long as a film is substantially formed on the surface of the hair or the surface of the fiber for a headdress product, and can be appropriately adjusted according to the amount and quality of the hair or the fiber for a headdress product, and can be, for example, in the range of 10 seconds to 120 minutes.

[0305] After drying, brushing or the like may be performed to disperse the hair or the fibers of the hair ornament product.

[0306] The hair or hair ornament fiber treated by the treatment method of the present invention has a good touch in a dry state. In addition, the touch of the hair or hair ornament fiber when the treatment agent is applied to the hair or hair ornament fiber and dried, and then cleaned or rinsed (the touch of the hair or hair ornament fiber in a wet state) also becomes good.

[0307] When styling the hair or the fiber for a hair ornament product treated by the treatment method of the present invention, from the viewpoint of improving the styling effect and sustainability of the hair or the fiber for a hair ornament product, a step of styling the hair or the fiber for a hair ornament product while heating the hair or the fiber for a hair ornament product (heat setting step) may be performed.

[0308] As a method for heating the hair or the fiber for a hair ornament product, there can be mentioned a method using a hair dryer, a hair iron, a hot curler, etc. Among these, from the viewpoint of effectively exerting the effect of improving the slidability of the hair iron in the second invention, the method using the hair iron is preferred.

[0309] The temperature of the hair surface or the hair ornament fiber surface when heating the hair or the hair ornament fiber is preferably 40°C or higher, more preferably 50°C or higher, more preferably 60°C or higher, more preferably 70°C or higher, and more preferably 75°C or higher, from the viewpoint of improving the styling effect and sustainability of the hair or the hair ornament fiber and obtaining a natural finishing feeling. In addition, from the viewpoint of obtaining a natural finishing feeling and suppressing heat damage to the hair or the hair ornament fiber, the temperature of the hair surface or the hair ornament fiber surface when heating the hair or the hair ornament fiber is preferably 220°C or lower, more preferably 200°C or lower, more preferably 190°C or lower, and even more preferably 150°C or lower. The heating time of the hair or the hair ornament fiber can be any range as long as the hair or the hair ornament fiber can be styling as desired.

[0467] <Dry touch>

[0468] A tress of 30 cm in length and 5 g in weight was prepared from straight hair of Japanese women that had not been chemically treated, washed with a plain shampoo having the following composition, and then completely dried with a hair dryer ("Nobby Professional Protection Ion Hair Dryer NIB3000 [SPEED MODE]" manufactured by Tescom Denki Co., Ltd.).

[0469] The hair treatment agents of each example were mixed uniformly and applied to the hair bundle at a bath ratio of 1:0.2 (hair mass: hair treatment agent mass). Then, the hair was dried by blowing warm air for 2 minutes from a position 15 cm away from the hair bundle using the hair dryer described above while combing. The hair surface temperature was 55 to 60°C. The hair surface temperature was measured by irradiating infrared rays vertically to the hair from a position 10 cm away from the hair bundle using an infrared radiation thermometer ("SK-8940" manufactured by Sato Metering Instruments Co., Ltd.). The touch of the dried hair bundle was evaluated by three professional sensory inspectors according to the following criteria, and the total score of the three inspectors was calculated.

[0479] *2: AMINON L-02 (manufactured by Kao Corporation)

[0480] <Wet touch>

[0481] A hair tress was prepared by the same method as the evaluation of "feel in dry state", and the hair treatment agent of each example was applied to the hair tress, followed by drying. The dried hair tress was washed with a normal shampoo of the above composition and then rinsed with warm water at 40°C. The feel of the hair tress at this time was sensory evaluated by three professional sensory inspectors according to the following criteria, and the total score of the three inspectors was calculated. As the untreated hair tress, a hair tress washed with a normal shampoo of the above composition and then rinsed with warm water at 40°C was used.

[0488] <Providing a fluffy feel when styling>

[0489] Using straight hair from Caucasian women who had not received any chemical treatment, a 6 cm x 6 cm square was created with a density of 200 strands / cm 2 , a hair bundle of 30 cm in length was transplanted at a growth angle of 60°. After washing with a common shampoo of the above composition, it was completely dried using a hair dryer ("Nobby Professional Protection Ion Hair Dryer NIB3000 [SPEED MODE]" manufactured by Tescom Denki Co., Ltd.).

[0490] The hair treatment agents listed in Tables 1 to 3 were mixed uniformly and applied to the hair bundle at a bath ratio of 1:0.2 (hair mass: hair treatment agent mass). Then, the hair bundle was dried by blowing warm air for 2 minutes from a position 15 cm away from the hair bundle while combing. The hair bundle was washed again with the ordinary shampoo of the above composition and dried with a towel, and completely dried with the above hair dryer with the hair ends facing downward. The fluffy feeling of the dried hair bundle when it was inverted on a table was visually evaluated by 3 professional sensory inspectors according to the following criteria, and the total score of the 3 inspectors was calculated. For an untreated hair bundle, the hair bundle was washed with the ordinary shampoo of the above composition and dried with a towel, and completely dried with the above hair dryer with the hair ends facing downward, and the hair bundle was similarly inverted on the table for comparison. In addition, the hair surface temperature during drying was 55 to 60°C. The hair surface temperature was measured by irradiating infrared rays vertically to the hair from a position 10 cm away from the hair bundle using an infrared radiation thermometer ("SK-8940" manufactured by Sato Keiki Mfg. Co., Ltd.).

[0491] (Evaluation Criteria)

[0492] 5: Fully fluffy.

[0496] 1: No volume (same as untreated hair).

[0497] <Heat setting property>

[0498] A hair bundle of 30 cm in length and 1 g in weight was prepared from untreated Caucasian female curly hair, which was washed with a common shampoo of the above composition and then dried naturally.

[0499] The hair treatment agents of each example were mixed uniformly and applied to the hair bundle at a bath ratio of 1:0.2 (hair mass: hair treatment agent mass). Then, the hair bundle was dried by blowing warm air for 2 minutes from a position 15 cm away from the hair bundle using the hair dryer, followed by blowing cold air for 1 minute.

[0500] The dried hair bundle was clamped with a flat hair iron ("One am digital hair iron for straightening 38mm AHI-938" manufactured by Miki Electric Industry Co., Ltd., set to 180°C) and slid at a speed of 10 cm / sec to perform heat styling. The hair bundle subjected to heat styling was visually evaluated by three professional sensory inspectors according to the following criteria, and the total score of the three inspectors was calculated. The hair surface temperature during the perming was 130 to 140°C. The hair surface temperature was measured by irradiating infrared rays vertically to the hair from a position 10 cm away from the hair bundle using an infrared radiation thermometer ("SK-8940" manufactured by Sato Metering Co., Ltd.).

[0501] (Evaluation Criteria)

[0502] 5: The curls of the hair are straightened and the hair strands are neat overall.

[0503] 4: The hair curls are stretched and the hair strands are generally neat.

[0504] 3: The hair curls and stretches, but the hair strands are less neat.

[0505] 2: The curls of the hair are roughly stretched, but there is no neatness of the hair strands.

[0506] 1: The curls of the hair are not stretched out and are not neat.

[0507] <Shampooing resistance (ability to impart volume when styling hair after 7 shampooings)>

[0508] The hair bundle treated and dried in the same manner as the above-mentioned evaluation of "the ability to provide a fluffy feeling during styling" was washed with the above-mentioned ordinary shampoo, rinsed with 40°C warm water and dried, and this step was repeated 6 times. The hair bundle washed and dried 6 times was washed again with the above-mentioned ordinary shampoo, dried with a towel, and completely dried with the above-mentioned hair dryer with the hair ends facing downward. The fluffy feeling when the dried hair bundle was placed upside down on the table was evaluated in the same manner as above. The untreated hair bundle was washed with the above-mentioned ordinary shampoo, dried with a towel, and completely dried with the above-mentioned hair dryer with the hair ends facing downward for comparison.

[0509] <Shampooing resistance (heat setting after 7 shampooings)>

[0510] The hair bundle treated and dried in the same manner as the above-mentioned evaluation of "heat setting property" was washed with a normal shampoo of the above-mentioned composition, rinsed with warm water at 40°C and dried, and this process was repeated 7 times. The hair bundle washed and dried 7 times was heat styled in the same manner as above to evaluate the heat setting property.

[0511] <Sliding properties of hair iron>

[0512] A hair bundle of 30 cm in length and 1 g in weight was prepared from untreated Caucasian female curly hair, which was washed with a common shampoo of the above composition and then dried naturally.

[0513] The hair treatment agents listed in Table 4 were mixed uniformly and applied to the hair bundle at a bath ratio of 1:0.2 (hair mass: hair treatment agent mass). Next, the hair bundle was dried by blowing warm air for 2 minutes from a position 15 cm away from the hair bundle using the hair dryer mentioned above while combing. Then, cold air was blown for 1 minute. The hair bundle was fixed to a spring balance, and then the hair was clamped with a hair iron ("One am Digital Hair Iron Straightening 38mm AHI-938" manufactured by Miki Electric Industry Co., Ltd., set to 180°C) and slid at a speed of 10 cm / sec for heat styling. The maximum value of the load (g) displayed on the spring balance at this time was recorded. The above measurement was repeated 10 times, and the average value of the maximum load was calculated and shown in Table 4. The smaller the value, the better the sliding property of the hair iron.
