Description

[Technical field]

[0001] The present invention relates to a hair treatment agent or a fiber treatment agent for head accessories such as wigs and extensions. [Background technology]

[0002] 2. Description of the Related Art In recent years, in the field of cosmetics, techniques for forming hydrophobic films have been investigated as a method for imparting various properties such as gloss and good feel to keratinous substances such as skin and hair. A technique using a silicone-based film-forming polymer as a hydrophobic film-forming polymer is known.For example, Patent Document 1 discloses a topical personal care composition for use in hair styling compositions, which comprises: 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 water-insoluble at 25°C and has 1-100 siloxy units, selected from the group consisting of silicone fluids and waxes, silanes, silicone resins, and mixtures thereof; and the weight ratio of the polysiloxane-grafted adhesive polymer to the drying aid is equal to or less than a predetermined value.And it is disclosed that the composition can reduce the drying time of the hair styling composition without any substantial loss of hair retention performance when completely dried.

[0003] Furthermore, since the properties imparted to keratinous materials by cosmetics or to fibers for head accessories by fiber treatment agents are often lost through friction caused by daily activities or after one washing, there is a demand for cosmetics or fiber treatment agents with excellent durability of effect. Generally, films formed by silicone-based film-forming polymers are hard and brittle, so studies are being conducted to improve the feel and durability. For example, Patent Documents 2 and 3 disclose a structural unit (R 1 3SiO 1 / 2 ), (R 2 2SiO 2 / 2 ), (R 3 SiO 3 / 2 ), and (SiO4 / 2 )(wherein, R 1 , R 2 and R 3 are 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 of each structural unit and the weight-average molecular weight are within a specified range. This cosmetic preparation is characterized by being formulated with a silicone resin that is not sticky when applied, spreads easily, has a good feel when used, has good water resistance, and adheres well to the skin, resulting in excellent cosmetic durability, and can prevent adhesion to clothing and the like (secondary adhesion).

[0004] Patent Document 4 discloses a cosmetic composition capable of forming a multi-layer structure after application to a keratinous substance, the cosmetic composition comprising at least one silicone and / or hydrocarbon-containing film former having at least one glass transition temperature of less than 60°C and one or more silicone compounds in a predetermined weight ratio in an amount sufficient to realize a viscosity of about 1,000 cSt to 22,000,000 cSt, and describes that the composition has improved cosmetic properties upon application, in particular good durability, feel, shine, brightness, and / or matte feel properties.

[0005] Patent Document 5 discloses that a phenyl silicone resin, which is represented by a specific composition formula and has a weight average molecular weight and a film refractive index each falling within a specific range, is soluble in organic oily components such as silicone oil and hydrocarbon oil, and can produce a uniform continuous film, which is neither sticky nor brittle and has good compatibility with ultraviolet absorbents. It also discloses that cosmetics containing the phenyl silicone resin have a good feel when used and can prevent adhesion to clothing, etc. (secondary adhesion).

[0007] It is desired that hair treatment agents and fiber treatment agents for head decoration products such as wigs can impart a good feel not only to dry hair and fibers for head decoration products, but also to wet hair and fibers for head decoration products. As described in Patent Document 1, among hair treatment agents and fiber treatment agents for head ornament products, styling agents are desired to improve the shape retention performance of hair or fibers for head ornament products. Specific examples of the shape retention performance of hair or fibers for head ornament products include the ability to clearly set the hair when styling with heating using a hair iron or the like (heat setting ability) and the ability to not easily lose heat setting ability even when washing the hair after applying the hair treatment agent or fiber treatment agent for head ornament products. Furthermore, in heat setting of hair or head-decorating fiber products, the smoothness of the hair when using a hair iron (smoothness of the hair iron) is also important. However, Patent Documents 1 to 5 do not disclose hair treatment agents or fiber treatment agents for head accessories that can achieve all of these effects.

[0008] The object of the present invention is to provide a hair treatment agent or a treatment agent for fibers for head ornament products which can impart a good feel to hair or fibers for head ornament products in both dry and wet states, which exhibits excellent heat setting properties and smoothness with a hair iron during styling, and which can suppress a decrease in heat setting properties even after washing the hair. [Means for solving the problem]

[0009] The present inventors have discovered that the above-mentioned problems can be solved by a hair treatment agent or a fiber treatment agent for head ornaments which contains a silicone film-forming polymer and other film-forming polymers having specific structural units, a high molecular weight organopolysiloxane whose degree of polymerization is within a specific range, and an organopolysiloxane having a polyalkylene oxide moiety and a cationic group, and have thus completed the present invention. That is, the present invention relates to the following. [1] A hair treatment agent or a fiber treatment agent for head accessories, comprising the following components (A) to (D): (A)(R 1 )3SiO 1 / 2 (R 1 represents a hydrocarbon group having 1 to 12 carbon atoms which may be substituted with fluorine or a hydroxyl group. 1 may be the same or different. 4 / 2 A film-forming polymer containing Q units represented by (B) A film-forming polymer other than component (A), excluding cationic polymers containing quaternary ammonium cations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] [Definition] "Polymer," as used herein, means a compound corresponding to the repeating of one or more units (which units are derived from compounds known as monomers) that are repeated at least twice, and preferably at least three times. "Hair" as used herein primarily refers to hair on the head, and also includes hair used in head decoration products. "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 product. "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 film, preferably a solid film, on the substrate to which it is applied. As used herein, "durability" primarily means that the effect imparted by the hair treatment agent or the treatment agent for fibers for head ornament products continues even when the hair is washed after application of the hair treatment agent or the treatment agent for fibers for head ornament products (washing resistance). Unless otherwise specified in this specification, it is synonymous with "sustained effect of heat setting after washing." In addition, in the description of this specification, "washing hair" also includes washing the fibers for head ornament products. In the following description, the hair treatment agent and the treatment agent for fibers for head ornament products may be collectively referred to as "treatment agent." "Good feel when wet on hair or fibers for a head accessory" means that the feel of the hair or fibers for a head accessory is good when the treatment is applied to the hair or fibers for a head accessory, dried, washed, and rinsed. "Volatile" as used herein means having a boiling point of 260° C. or less at normal pressure.

[0012] [Hair treatment agents or fiber treatment agents for head accessories] The hair treatment agent or fiber treatment agent for head decoration products of the present invention contains the following components (A) to (D). (A)(R1 )3SiO 1 / 2 (R 1 represents a hydrocarbon group having 1 to 12 carbon atoms which may be substituted with fluorine or a hydroxyl group. 1 may be the same or different. 4 / 2 A film-forming polymer containing Q units represented by (B) A film-forming polymer other than component (A), excluding cationic polymers containing quaternary ammonium cations. (C) A high molecular weight organopolysiloxane having a degree of polymerization of 2,200 or more and 20,000 or less. (D) An organopolysiloxane other than the components (A) to (C) that has a polyalkylene oxide moiety and a cationic group. By virtue of having the above-described configuration, the hair treatment agent or fiber treatment agent for head ornament products of the present invention can impart a good feel to hair or fibers for head ornament products in both dry and wet states, exhibit excellent heat setting properties and hair iron slippage during styling, and can suppress a decrease in heat setting properties even after washing the hair.

[0013] The reason why the hair treatment agent or fiber treatment agent for head ornament products of the present invention exhibits the above-mentioned effects is not clear, but is presumed to be as follows. The hair treatment agent or fiber treatment agent for head accessories of the present invention contains components (A) and (B), and when applied to hair or fibers for head accessories, it is capable of forming a highly hydrophobic film on the surface of the hair or fibers for head accessories. It is believed that the film-forming effect improves the heat setting property during styling. Since component (A) contains the Q unit, it can form a hard film, but since the film is hard and brittle, it is easily peeled off by friction, washing, etc., and may further lead to a decrease in the feel of the hair or fibers for head accessories. However, by also containing component (B), the hair treatment agent or fiber treatment agent for head accessories of the present invention can form a film that is softer than a film consisting of component (A) alone, and it is therefore believed that the decrease in the feel of the hair or fibers for head accessories and the decrease in heat setting ability after washing can also be suppressed. It is believed that component (C) undergoes phase separation in the formed hydrophobic film, and is present in large amounts on the surface side (air side) of the film. This is believed to provide a protective function for the hair surface or the surface of fibers for head accessories, and also contribute to improved feel and durability. In particular, it is believed that component (C), having a predetermined degree of polymerization, can prevent stickiness from occurring in both dry and wet hair or fibers for head accessories, and provide a good feel. It is believed that component (D) has the effect of accelerating the phase separation in the hydrophobic film, which makes it easier for component (C), which is highly hydrophobic and has low surface tension, to be unevenly distributed on the surface of the film, reducing the frictional force of the surface of the film that is formed, and improving the feel, durability, and smoothness of the hair iron. The mechanism of action of the present invention is not limited to the above.

[0014] <Fibers for hair and head accessories> The treatment agent of the present invention is applied to hair or fibers for head accessories, and among these, hair is more preferred. The fibers for head ornament products to which the treatment agent of the present invention is applied may be either naturally derived fibers or synthetic fibers, but naturally derived fibers are preferred.

Among these, fibers artificially manufactured using polymers and oligomers such as proteins and polysaccharides derived from animal hair, human hair, or proteins and polysaccharides derived from keratin, collagen, casein, soybeans, peanuts, corn, silk waste, silk protein (e.g., silk fibroin), etc. as raw materials are preferred, regenerated protein fibers derived from proteins derived from keratin, collagen, casein, soybean protein, peanut protein, corn protein, silk protein (e.g., silk fibroin), etc. as raw materials are more preferred, regenerated protein fibers such as regenerated collagen fibers derived from collagen as raw materials, regenerated silk fibers derived from silk fibroin as raw materials, etc. are more preferred, and regenerated collagen fibers are 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. for quality improvement. Furthermore, regenerated collagen fibers may be post-processed or post-treated. Filaments are preferred as the form of regenerated collagen fibers. Filaments are generally taken out from bobbins or boxes. In addition, filaments coming out of the drying process in the manufacturing process of regenerated collagen fibers can be used directly.

EXAMPLES

[0135] 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.

[0136] <Viscosity> The steady shear viscosity of the hair treatment agent was measured using a Brookfield viscometer (Toki Sangyo Co., Ltd., TVB-10, rotor L / Adp) at 30° C. and a rotor rotation speed of 60 rpm.

[0137] <Feel when dry> A tress measuring 30 cm in length and weighing 5 g was made from straight hair of a Japanese woman that had not been chemically treated. It was washed with plain shampoo of the composition below, and then completely dried with a hair dryer (Tescom Denki Co., Ltd. Nobby Professional Protect Ion Hair Dryer NIB3000 [SPEED mode]). The hair treatment agents of each example were mixed uniformly and applied to the tresses in a bath ratio of 1:0.2 (mass of hair:mass of hair treatment agent). Next, the hair was dried by applying hot air from a position 15 cm away from the tresses for 2 minutes using the dryer while combing, and then applying cold air for 1 minute. The hair surface temperature was 55-60°C. The hair surface temperature was measured using an infrared radiation thermometer ("SK-8940" manufactured by Sato Keiryoki Seisakusho Co., Ltd.) from a position 10 cm away from the hair tresses, with infrared rays irradiated perpendicularly to the hair. The feel of the tresses after drying was evaluated by three expert panelists according to the following criteria, and the total score of the three panelists was calculated. (Evaluation Criteria) 5: No sticky feeling at all 4: Almost no stickiness 3: Almost no stickiness 2: Feels slightly sticky 1: Sticky feeling

[0138] (Plain Shampoo Composition) Ingredients (mass%) Sodium polyoxyethylene (2) lauryl ether sulfate (*1) 15.5 Lauric acid diethanolamide (*2) 1.5 EDTA tetrasodium salt 0.3 Sodium benzoate 1.43 Purified water remaining amount Total 100.0 *1: 57.4% by weight of Emeral 227 (manufactured by Kao Corporation, active ingredient 27% by weight) *2: Aminone L-02 (Kao Corporation)

[0139] <Feel when wet> A tress was prepared in the same manner as in the evaluation of "feel in dry state", and the hair treatment agent of each example was applied to the tress, and then it was dried. After drying, the tress was washed with the plain shampoo of the above composition, and then rinsed with warm water at 40°C. The feel of the tress when rinsed was evaluated by three expert panelists according to the following criteria, and the total score of the three panelists was calculated. The untreated tress was used after washing with the plain shampoo of the above composition and rinsing with warm water at 40°C. (Evaluation Criteria) 5: Smooth and easy to run your fingers through 4: Slightly smooth, with almost no resistance to the fingers 3: The texture is as smooth as untreated tresses. 2: I feel a little bit of resistance when I use it. 1: Difficult to run your fingers through

[0140] <Heat setting properties> A tress measuring 30 cm in length and 1 g in mass was prepared using curly hair from a Caucasian woman that had not been subjected to any chemical treatment. The tress was washed with the above-mentioned plain shampoo and then allowed to air dry. The hair treatments of each example were mixed uniformly and applied to the tresses in a bath ratio of 1:0.2 (mass of hair:mass of hair treatment).Then, using the hair dryer, hot air was blown from a position 15 cm away from the tresses for 2 minutes while combing, and then cold air was blown for 1 minute to dry the tresses. After drying, the hair was heat-styled by clamping it with a flat hair iron (Miki Electric Industry Co., Ltd.'s "One am Digital Hair Iron for Straightening 38 mm AHI-938", set temperature 180°C) and sliding it at a speed of 10 cm / sec. The tresses that had been heat-styled were visually evaluated by three expert panelists according to the following criteria, and the total score of the three panelists was calculated. The hair surface temperature during the ironing was 130-140°C. The hair surface temperature was measured using an infrared radiation thermometer (Sato Keiryoki Seisakusho Co., Ltd.'s "SK-8940") from a position 10 cm from the hair tress, with infrared rays irradiated perpendicularly to the hair. (Evaluation Criteria) 5: The curls of the hair are straight and the whole tress is neatly arranged. 4: The curls have straightened out and the entire tress is almost neat. 3: The curls are growing, but the tresses are not as tightly held together. 2: The curls in my hair are mostly straightened out, but the tresses are not in place. 1: Hair curls do not straighten and are not manageable

[0141] <Hair wash resistance (heat setting ability after 7 washes)> The tresses were treated and dried in the same manner as in the above evaluation of "heat setting ability", washed with the plain shampoo of the above composition, rinsed with warm water at 40°C, and dried, and this process was repeated seven times. After washing and drying seven times, the tresses were heat-styled in the same manner as above, and the heat setting ability was evaluated.

[0142] <Smoothness of hair iron> A tress measuring 30 cm in length and 1 g in mass was prepared using curly hair from a Caucasian woman that had not been subjected to any chemical treatment. The tress was washed with the above-mentioned plain shampoo and then allowed to air dry. The hair treatment agent of each example was mixed uniformly and applied to the tress in a bath ratio of 1:0.2 (mass of hair:mass of hair treatment agent). Next, using the dryer, hot air was applied from a position 15 cm away from the tress for 2 minutes while combing, and then cold air was applied for 1 minute to dry. The tress was fixed to a spring scale, and then a flat hair iron (Miki Electric Industry Co., Ltd. "One am digital hair iron for straightening 38 mm AHI-938", set temperature 180 ° C.) was used to pinch the hair and slide it at a speed of 10 cm / sec to perform heat styling. At this time, the maximum value of the load (g) displayed on the spring scale was recorded. The above measurement was repeated 10 times, and the average of the maximum load was calculated and shown in Table 1. The smaller the value, the better the smoothness of the hair iron.

[0143] Examples 1 to 7 and Comparative Examples 1 to 3 (Preparation and Evaluation of Hair Treatment Agents (Hair Styling Agents)) The components shown in Table 1 were blended in the proportions shown in the table and mixed until uniform to prepare a hair treatment. The hair treatment thus obtained was used to carry out various evaluations using the methods described above. The results are shown in Table 1. The blend amounts (mass %) shown in Table 1 are all amounts of active ingredients.
