Description

[Technical Field]

[0001] The present invention relates to a method for treating keratinous materials or fibers for headwear. [Background technology]

[0002] Keratinous materials are sometimes colored or bleached artificially for the purpose of improving fashion, such as dyeing hair with hair dyes, bleaching hair, or dyeing nails with nail polish. However, the coloring or bleaching effect can be lost due to friction caused by daily activities, discoloration over time, or even after a single wash. Therefore, methods for maintaining the coloring or bleaching effect on keratinous materials or fibers for head accessories such as wigs are being investigated.

[0003] For example, Patent Document 1 discloses a method for improving color retention in artificially colored hair, which comprises applying to artificially colored hair a composition that includes a hydrophobic particulate material having a predetermined particle size, a silicone-based hydrophobic film-forming agent, and a medium containing a volatile hydrocarbon or silicone solution, and that has a content of non-volatile water-soluble or water-dispersible organic components less than a predetermined value.

[0004] [Patent Document 1] Special Publication No. 2013-541585 Summary of the Invention [Problem to be solved by the invention]

[0005] The technique disclosed in Patent Document 1 describes applying a composition to colored hair (wet or dry) after each shampooing. However, this method requires applying the composition to hair every time shampooing is performed, and there is room for improvement in terms of the durability of the coloring effect. Furthermore, from the viewpoint of reducing the number of times that colored keratinous materials need to be washed and further improving color durability, it is preferable to impart stain resistance (stain resistance) to the treated keratinous materials. However, Patent Document 1 does not consider imparting stain resistance to keratinous materials.

[0006] The present invention relates to a method for treating artificially colored or bleached keratinous materials or fibers for headwear, which can improve the color durability of keratinous materials or fibers for headwear even with a single treatment and can also impart a stain-resistant effect. [Means for solving the problem]

[0007] The present inventors discovered that the above-mentioned problems can be solved by treating artificially colored or bleached keratinous materials or fibers for headwear with a composition containing a silicone film-forming agent and an organopolysiloxane having a degree of polymerization of 100 or more in a specified mass ratio, and thus completed the present invention. That is, the present invention relates to the following. [1] A method for treating artificially colored or bleached keratinous materials or headwear fibers with a composition, the method comprising the step of applying the composition to the keratinous materials or headwear fibers; The composition comprises the following components (A) and (B): (A) Silicone film-forming agent (B) Organopolysiloxane with a degree of polymerization of 100 or more wherein the ratio of the mass of component (A) to the total mass of component (A) and component (B) [(A) / {(A)+(B)}] is 10% or more. [2] A fiber treatment kit for keratin materials or headwear products, comprising: a first agent containing one or more selected from the group consisting of colorants and bleaching agents; and a second agent containing the following components (A) and (B), in which the ratio of the mass content of component (A) to the total mass content of components (A) and (B) [(A) / {(A)+(B)}] is 10% or more. (A) Silicone film-forming agent (B) Organopolysiloxane with a degree of polymerization of 100 or more [Effects of the Invention]

[0008] According to the present invention, even with a single treatment, it is possible to improve the color durability of artificially colored or bleached keratin materials or fibers for headwear products, and further to impart a stain-resistant effect. DETAILED DESCRIPTION OF THE INVENTION

[0009] [Definition] "Polymer," as used herein, means a compound corresponding to the repetition of one or more units (these units are derived from compounds known as monomers), which or these units are repeated at least twice, and preferably at least three times. As used herein, "keratinous materials" includes, for example, skin, eyebrows, eyelashes, hair, nails, etc. of animals such as humans, as well as artificially produced keratinous materials (excluding fibers for head accessories). "Hair" as used herein means human head hair, but also includes hair that has been cut off from the human head. "Headwearing products" as used herein means, for example, hair wigs, hairpieces, weaving, hair extensions, braided hair, hair accessories, doll hair, and the like. "Headwear fiber" as used herein means a fiber used in the headwear. "Hydrophobic," as used herein, means that a substance has a solubility in water of less than 1% by weight at 25°C. "Film-forming," as used herein, means leaving a solid film on the substrate to which it is applied. "Volatile" as used herein means having a boiling point of 260°C or less at atmospheric pressure.

[0010] [Method for treating keratinous materials or fibers for headwear products] The method for treating keratinous materials or fibers for headwear of the present invention (hereinafter also referred to as "the method of the present invention") is a method for treating artificially colored or bleached keratinous materials or fibers for headwear with a composition, the method comprising the step of applying the composition to the keratinous materials or fibers for headwear, The composition comprises the following components (A) and (B): (A) Silicone film-forming agent (B) Organopolysiloxane with a degree of polymerization of 100 or more The ratio of the mass of component (A) to the total mass of components (A) and (B) [(A) / {(A)+(B)}] is 10% or more. By adopting the above-described configuration, the present invention can improve the color durability of artificially colored or bleached keratinous materials or fibers for headwear, even with a single treatment, and further impart a stain-resistant effect. That is, the method of the present invention relates to a method for protecting the color of artificially colored or bleached keratinous materials or fibers for headwear, and a method for imparting a stain-resistant effect to artificially colored or bleached keratinous materials or fibers for headwear. The term "single treatment" as used herein means that the composition is applied once, although the method of the present invention is not limited to treating artificially colored or bleached keratinous materials or headwear fibers only once, and may involve multiple treatments.

[0011] The reason why the present invention has the above-mentioned effects is not clear, but is presumed to be as follows. The composition used in the treatment method of the present invention contains components (A) and (B), and is therefore capable of forming a hydrophobic film on the surface of artificially colored or bleached keratinous materials or fibers for headwear. Component (A) is a hydrophobic film-forming agent that maintains the strength and durability of the film, which is believed to inhibit color change of keratinous materials or fibers for headwear due to friction, washing, etc. Meanwhile, component (B) is believed to be present in greater amounts on the surface side (air side) of the film formed. Having a degree of polymerization equal to or greater than a predetermined value, it is believed to provide surface protection for keratinous materials or fibers for headwear and to provide stain resistance. Because components (A) and (B) are compatible, their synergistic effects are believed to improve color retention and provide stain resistance when applied to the surface of artificially colored or bleached keratinous materials or fibers for headwear. Furthermore, it is believed that when the ratio of the mass content of component (A) to the total mass content of components (A) and (B) in the composition [(A) / {(A)+(B)}] is 10% or more, a film that is more durable to washing, etc. is formed. Therefore, it is believed that even a single treatment can achieve color retention and stain prevention effects for artificially colored or bleached keratinous materials or fibers for headwear. The mechanism of action of the present invention is not limited to the above.

Regenerated protein fibers made from keratin, collagen, casein, soybean protein, peanut protein, corn protein, silk protein (e.g., silk fibroin), and the like are more preferred. Regenerated protein fibers such as regenerated collagen fibers made from collagen and regenerated silk fibers made from silk fibroin are even more preferred, with regenerated collagen fibers being even more preferred. 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-treated. The preferred form of regenerated collagen fibers is filaments. Filaments are generally taken out from bobbins or boxes.

[Example]

[0132] The present invention will be described below with reference to examples, but the present invention is not limited to the scope of the examples. In the examples, various measurements and evaluations were carried out by the following methods.

[0133] <Hair treatment method> A 100% human white hair bundle (manufactured by Beaulux Co., Ltd., 10 cm long, 1 g mass) was washed with plain shampoo of the following composition, then rinsed with warm water at 40°C and thoroughly dried. 0.30 g of a hair dye composition of the following composition (dispersion of carbon black (1% by mass) in isododecane) was applied to the bundle, followed by drying with a hair dryer (artificial coloring). 0.20 g of each hair cosmetic composition was then applied, followed by drying with a hair dryer, to perform a hair treatment.

[0134] (Plain shampoo composition) Ingredients (mass %) Sodium Polyoxyethylene (2) Lauryl Ether Sulfate (*1) 15.5 Lauric acid diethanolamide (*2) 1.5 edetic acid tetrasodium salt 0.3 Sodium benzoate 1.43 Refined water residue Total 100.0 *1: 57.4% by mass of Emar 227 (manufactured by Kao Corporation, active ingredient 27% by mass) *2: Aminone L-02 (Kao Corporation)

[0135] (Composition of hair dye composition) Ingredients (mass %) Carbon black (*1) 1.0 イソドデカン(*2) remaining quantity Total 100.0 *1: ISD-CB2, manufactured by Daito Kasei Kogyo Co., Ltd., carbon black (15% by mass) solution in isododecane *2: Marukasol R, manufactured by Maruzen Petrochemical Co., Ltd., isododecane

[0136] <Color durability (wash-resistant)> The hair bundle after the treatment was measured using a color difference meter (Konica Minolta, Inc., CR-400) with a D65 light source in the CIE color system (L * ,a * ,b * After washing the hair seven times and drying it, the hair bundle was similarly measured with a color difference meter, and the color difference (ΔE * ) was calculated. * ,a * ,b * Measurements were taken at six different points on the hair bundle (one point on each side of the center of each of the three equal areas that were divided into the lengthwise direction), and the average value was calculated.

number

[0137] <Difficulty in stain adhesion> 20 μL of each hair cosmetic composition was dropped onto a commercially available PET film (Toray Industries, Inc.; Lumirror Film T60-A4-100 μm), spread using a bar coater (AS ONE Corporation, No. 3), and allowed to dry naturally to form a coating film. The area where the coating film was formed was then cut into a 3 cm x 3 cm piece to prepare a test film. The mass of this film was designated F0 [g]. Zirconia beads (Nikkato Corporation, "YTZ Balls," Φ = 1 mm) were used as a model of physical soiling. 10.4 g of zirconia beads were placed in a balance dish (AS ONE Corporation, BD-2) and leveled, and the coating surface of a film cut into a 3 cm x 3 cm size was placed on top of the balance dish. Next, the balance dish was placed on top of the film, and a weight of 200 g, made from a standard bottle (AS ONE Corporation, No. 11) filled with tap water, was placed on top of the balance dish for 30 seconds, after which the weight was removed and the mass of the film with the beads attached (referred to as F1 [g]) was measured. The bead adhesion rate was calculated from the change in the film mass before and after contact with the beads using the following formula: The mass of beads required to cover 100% of the 3 cm x 3 cm test film area was 2.68 g (average of two measurements). Bead adhesion rate [%] = (F1 - F0 [g]) ÷ (mass of beads that cover 100% of the test film area [g]) × 100 The above test was carried out twice, and the average values ​​are shown in Table 1. When the adhesion rate was 25% or less, it was difficult for the surface to be soiled, when it was 20% or less it was even more difficult, when it was 15% or less it was even more difficult, and when it was 5% or less it was even more difficult for the surface to be soiled.

[0138] Examples 1 to 19 and Comparative Examples 1 to 3 (Preparation and Evaluation of Hair Cosmetic Compositions) The components shown in Tables 1 to 4 were blended in the proportions shown in each table and mixed until uniform to prepare hair cosmetic compositions. The resulting hair cosmetic compositions were evaluated using the methods described above. The results are shown in Tables 1 to 4. The blending amounts (mass %) shown in the tables are all amounts of active ingredients.

[0139] [Table 1]

[0140] [Table 2]

[0141] [Table 3]

[0142] [Table 4]

[0143] Example 20 As the fiber for the head accessory product, Kaneka Corporation's regenerated collagen fiber "Nextension Crystal XXL 30" (color number: 30 (white), shape: straight) was used to create an artificial hair bundle measuring 10 cm in length, 1.5 cm in width, and 1 g in mass. The artificial coloring and hair treatment were carried out in the same manner as in Example 1, except that the above-mentioned artificial hair bundle was used instead of the human white hair (100%) bundle in Example 1, and the above-mentioned evaluation was carried out. The results are shown in Table 5.

[0144] [Table 5]

[0145] The ingredients listed in the table are as follows: *1: X-21-5595, manufactured by Shin-Etsu Chemical Co., Ltd., isododecane solution of trimethylsiloxysilicate (60% by mass) *2: Silsoft B3020, manufactured by Momentive Performance Materials, dimethylpolysiloxane, viscosity at 25°C: 20 million mm 2 / s(degree of polymerization 3,546) *3: Marukasol R, manufactured by Maruzen Petrochemical Co., Ltd., isododecane *4: SR1000, manufactured by Momentive Performance Materials, trimethylsiloxysilicate *5: X-25-9074, manufactured by Shin-Etsu Chemical Co., Ltd., dimethylpolysiloxane, viscosity at 25°C: 30 million mm 2 / s(degree of polymerization 3,747) *6: X-21-5686, manufactured by Shin-Etsu Chemical Co., Ltd., dimethylpolysiloxane, viscosity at 25°C: 3 million mm 2 / s (degree of polymerization 2,680) *7: KF-96H-500,000cs, manufactured by Shin-Etsu Chemical Co., Ltd., dimethylpolysiloxane, viscosity at 25°C: 500,000 mm 2 / s(degree of polymerization 1,972) *8: KF-96H-300,000cs, manufactured by Shin-Etsu Chemical Co., Ltd., dimethylpolysiloxane, viscosity at 25°C: 300,000 mm 2 / s (degree of polymerization 1,790) *9: KF-96H-100,000cs, manufactured by Shin-Etsu Chemical Co., Ltd., dimethylpolysiloxane, viscosity at 25°C: 100,000 mm 2 / s(degree of polymerization 1,429) *10: KF-96H-10,000cs, manufactured by Shin-Etsu Chemical Co., Ltd., dimethylpolysiloxane, viscosity at 25°C: 10,000mm 2 / s (degree of polymerization 804) *11: KF-96-1,000cs, manufactured by Shin-Etsu Chemical Co., Ltd., dimethylpolysiloxane, viscosity at 25°C: 1,000mm 2 / s (degree of polymerization 357) *12: KP-550, manufactured by Shin-Etsu Chemical Co., Ltd., (acrylates / dimethicone) copolymer (40% by mass) solution in isododecane

[0146] The degree of polymerization (P) of the above components *2, 5 to 11 can be calculated from the viscosity (η) using the above formula (4) to determine the molecular weight (M), and since the molecular weight of the base unit of dimethylpolysiloxane is 74, the degree of polymerization (P) can be calculated using the following formula (5). P=M / 74 (5)

[0147] Tables 1 to 4 show that the treatment method of the present invention, with a single treatment, results in little color fading even after repeated washing of artificially colored hair, and good color retention. It is also clear that the method can impart a dirt-repellent effect to hair. In Comparative Example 1, a smooth film was not formed, making it impossible to evaluate "resistance to dirt adhesion." Furthermore, Table 5 shows that the treatment method of the present invention provides good color retention and stain prevention effects even when regenerated collagen fibers, which are fibers for head accessories, are used instead of hair. [Industrial Applicability]

[0148] According to the present invention, even with a single treatment, it is possible to improve the color durability of artificially colored or bleached keratin materials or fibers for headwear products, and further to impart a stain-resistant effect.
