Description

Technical Field

[0001] The present invention relates to a method for treating hair or fibers for hair ornament products.

Background Art

[0002] In addition to hair treatment effects such as hair detergency and hair conditioning effects, hair treatment agents are also desired to have good handleability, coatability on hair, and usability.

[0003] As a hair treatment agent capable of uniformly treating hair, a foamy treatment agent that does not use compressed gas or radiation gas is known. For example, Patent Document 1 discloses a foamy hair treatment agent produced by mixing two components before use, wherein (1) the first component is a powdery or granular solid and contains a water-soluble acid or a water-soluble acid salt that is physiologically harmless and a carbonate or bicarbonate that is physiologically harmless, and (2) the second component is a hair treatment agent containing water and contains 0.1 to 50% by weight of a surfactant. According to the disclosed technology of Patent Document 1, by adding a powder mixture composed of a water-soluble acid or a water-soluble acid salt that is physiologically harmless and a carbonate or bicarbonate that is physiologically harmless to a hair treatment agent containing water immediately before use, a stable, voluminous, and foamy hair treatment agent containing fine bubbles can be obtained without using compressed gas or radiation gas. Although it is possible to obtain a foamy hair treatment agent with an aerosol-type hair treatment agent, an aerosol container and a propellant such as compressed gas are required. According to the disclosed technology of Patent Document 1, there is an advantage that a foamy hair treatment agent can be obtained by a simpler method.

[0004] In addition, Patent Document 2 discloses a hair-growing composition comprising a liquid composition containing an acidic substance, a humectant, and water, and a powdery or gel-like composition containing a carbonate and a thickener, which is configured to be applied to the skin by mixing the liquid composition with the powdery or gel-like composition at the time of use, and has a high blood circulation promoting effect, thereby enhancing the hair-growing effect.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The foamy hair treatment agent disclosed in Patent Document 1 and the hair-growing composition disclosed in Patent Document 2 are used by mixing two agents at the time of use and causing carbon dioxide foaming to prepare a foamy composition. For such a two-agent type treatment agent composition, from the viewpoints of handleability during treatment and improvement of treatment effect, it is desired that the texture of the mixture obtained by mixing the two agents is good during use. Here, "good texture during use" means that the obtained mixture is foamy and does not drip easily during treatment. Furthermore, in a hair conditioning agent, it is important that the elongation during hair application is good in order to condition the hair uniformly and sufficiently. However, in the prior art, no hair treatment agent and hair treatment method that satisfy all the above required characteristics have been proposed. In addition, since the hair-growing composition disclosed in Patent Document 2 is a composition applied to the scalp, it does not mention hair treatment.

[0007] The present invention provides a method for treating hair or fibers for hair accessories, using a fiber treatment agent composition for hair or hair accessories, which has a good texture during use of the treatment agent composition and good elongation during application to hair or fibers for hair accessories, and can obtain an excellent treatment effect.

[0009] According to the present invention, in a method for treating hair or fibers for a hair accessory product using a hair or fiber treatment agent composition, the texture during use of the treatment agent composition is good, and the elongation during application to the hair or fibers for a hair accessory product is good, and it is possible to provide a method for treating hair or fibers for a hair accessory product that can obtain an excellent treatment effect. [Embodiments for Carrying Out the Invention]

[0010] [Definitions] "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). This or these units are repeated at least twice, preferably at least three times. "Hair", as used herein, mainly means hair on the head, and also includes hair used for hair accessory products. "Hair accessory product", as used herein, means, for example, a hair wig, a wig, a webbing, a hair extension, a blade hair, a hair accessory, a doll hair, etc. "Fibers for hair accessory products", as used herein, means fibers used for the hair accessory products. As used herein, the term "powder or granular composition" means a composition composed of an aggregate of particulate components that are solid at room temperature (excluding compression molded articles obtained by compression molding particulate components). The size (average particle diameter) of the particulate components is preferably 1 μm or more and 1000 μm or less from the viewpoint of ease of dissolution in the second agent. The particulate components may be granulated ones. As used herein, the phrase "good texture during use of the treatment agent composition" means that the appearance of the treatment agent composition prepared by mixing the first agent and the second agent is foamy and is not likely to drip during the treatment of hair or fibers for headgear products. The texture during use of the treatment agent composition can be specifically evaluated by the method described in the examples. As used herein, the terms "room temperature" and "normal temperature" mean 25°C unless otherwise specified.

[0011] [Method for treating hair or fibers for headgear products] The method for treating hair or fibers for headgear products of the present invention (hereinafter, also simply referred to as "(the method of the present invention) treatment method") comprises the following first agent and second agent: First agent: Powder or granular composition Second agent: A liquid composition containing (B) a cationic surfactant and water By mixing them at the time of use to foam and prepare a foamy treatment agent composition, and then applying the composition to hair or fibers for headgear products, the following components (A1), (A2) and (A3) are included in at least one of the first agent and the second agent (however, except when the total amount of component (A1) and the total amount of component (A2) are both included in the second agent). (A1) At least one selected from the group consisting of hydrogen carbonates and carbonates (A2) Organic acid (A3) Thickener Due to having the above configuration, the treatment method of the present invention provides a good texture during use of the prepared treatment agent composition, good elongation during application to hair or fibers for headgear products, and excellent treatment effects.

[0012] The reason why the present invention exhibits the above effects is considered as follows. In the treatment method of the present invention, the first agent and the second agent are mixed at the time of use to cause foaming, thereby preparing a foamed treatment agent composition. At least one of the first agent and the second agent contains (A1) one or more selected from the group consisting of hydrogen carbonates and carbonates, and (A2) an organic acid. Since the second agent is a liquid composition containing water, when the first agent and the second agent are mixed, component (A1) and component (A2) react in the mixture to generate carbon dioxide gas, and a foamed treatment agent composition is obtained. Since the first agent is in powder or granular form, carbon dioxide gas can be efficiently generated. Furthermore, since at least one of the first agent and the second agent contains (A3) a thickener, the second agent, which is a liquid composition containing water, can be efficiently thickened. Therefore, it is considered that the texture during the use of the foamed treatment agent composition is improved, and the elongation during application to hair or fibers for headgear products is also improved. However, in the present invention, the case where the total amount of component (A1) and the total amount of component (A2) are both contained in the second agent is excluded. This is because carbon dioxide gas foaming properties cannot be obtained in this case. Therefore, at least one of component (A1) and component (A2) is contained in the first agent. Since the second agent contains a cationic surfactant as component (B), it is suitable as a conditioning agent composition or a styling agent composition for hair or fibers for headgear products. Although the second agent alone can be used as a conditioning agent composition or a styling agent composition, it is considered that the above effects can be obtained when it is mixed with the first agent to form a foamed composition for treating hair or fibers for headgear products.

[0013] <Hair or fibers for headgear products> The application target of the treatment method of the present invention is hair or fibers for headgear products. Among these, hair is preferred.

Regenerated protein fibers such as regenerated collagen fibers made from collagen and regenerated silk fibers made from silk fibroin are more preferred, and regenerated collagen fibers are even more preferred. The regenerated collagen fiber can be manufactured by known techniques. The composition of the regenerated collagen fiber does not have to be 100% collagen, and natural polymers, synthetic polymers, additives, etc. for quality improvement may be included. Furthermore, the regenerated collagen fiber may be post-processed or post-treated. As the form of the regenerated collagen fiber, a filament is preferred. The filament is generally taken out from the bobbin-wound or box-packed state. Also, the filament coming out of the drying process in the manufacturing process of the regenerated collagen fiber can be directly used.
