Description

Technical Field

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

Background Art

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

[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, in Patent Document 1, in a foamy hair treatment agent produced by mixing two components before use, (1) the first component is a powdery or granular solid, a water-soluble acid that is physiologically non-problematic or a water-soluble acid salt that is physiologically non-problematic and a carbonate or bicarbonate that is physiologically non-problematic, and (2) the second component is a hair treatment agent containing water, and is characterized by containing 0.1 to 50 weight percent of a surfactant. According to the disclosed technique of Patent Document 1, by adding a powder mixture composed of a water-soluble acid that is physiologically non-problematic or a water-soluble acid salt that is physiologically non-problematic and a carbonate or bicarbonate that is physiologically non-problematic to a hair treatment agent containing water immediately before use, it is described that a stable, voluminous, 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 technique 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 growth 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 growth 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 growth composition disclosed in Patent Document 2 are used by mixing two agents at the time of use and carbonating to prepare a foamy composition. For such a two-agent type treatment agent composition, from the viewpoints of handling property 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 is not likely to drip during treatment. Furthermore, in a hair shampoo, it is important to obtain a sufficient amount of foam when washing the hair. However, in the prior art, no hair treatment agent and hair treatment method that satisfy all the above required characteristics have been proposed. Note that since the hair growth 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 ornaments using a fiber treatment agent composition for hair or hair ornaments, wherein the texture during use of the treatment agent composition is good, sufficient foam volume can be obtained when washing the hair or fibers for hair ornaments, and an excellent treatment effect can be obtained.

Embodiments for Carrying Out the Invention

[0010] [Definitions] As used herein, "polymer" 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. As used herein, "hair" mainly means scalp hair and also includes hair used for hair accessory products. As used herein, "hair accessory product" means, for example, a hair wig, a wig, a webbing, a hair extension, a blade hair, a hair accessory, a doll hair, etc. As used herein, "fiber for a hair accessory product" means a fiber used for the hair accessory product. In this specification, the "powder or granular composition" means a composition composed of an aggregate of particulate components that are solid at normal temperature (excluding compression molded articles obtained by compression molding particulate components). From the viewpoint of ease of dissolution in the second agent, the size (average particle diameter) of the particulate shape is preferably 1 μm or more and 1000 μm or less. The particulate components may be granulated ones. In this specification, "the texture during use of the treatment agent composition is good" means that the appearance of the treatment agent composition prepared by mixing the first agent and the second agent is foamy and it 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. In this specification, "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 at least one surfactant selected from the group consisting of (B) anionic surfactants, amphoteric surfactants, and nonionic surfactants, 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 has a good texture during use of the prepared treatment agent composition, and when washing hair or fibers for headgear products, a sufficient amount of foam can be obtained, and an excellent treatment effect can be obtained.

[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 foamy treatment agent composition. Since at least one of the first agent and the second agent contains (A1) one or more selected from the group consisting of hydrogen carbonate and carbonate, and (A2) an organic acid, and 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 foamy 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 thickening agent, the second agent, which is a liquid composition containing water, can be efficiently thickened, so that the texture during the use of the foamy treatment agent composition is improved, and it is considered that a sufficient amount of foam can be obtained when washing hair or fibers for headgear products. 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, as component (B), one or more surfactants selected from the group consisting of anionic surfactants, amphoteric surfactants, and nonionic surfactants, it is suitable as a cleaning agent composition for hair or fibers for headgear products. Although the second agent can be used alone as a cleaning agent composition, it is considered that the above effects can be obtained when it is mixed with the first agent to form a foamy 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.

The regenerated collagen fiber can be manufactured by a known technique. 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 a 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.

Examples

[0089] Hereinafter, examples of the present invention will be described, but the present invention is not limited to the scope of the examples. In this example, various evaluations were performed by the following methods.

[0090] <Carbon dioxide concentration at 20-fold dilution> 0.2 g of the first agent, 1.0 g of the second agent, and 19 g of ion-exchanged water described in the table were stirred with a spoon for 10 seconds to prepare a 20-fold dilution based on the second agent. The carbon dioxide concentration was measured with the probe of an ion meter ("IM-32P" manufactured by Toa DKK Corporation) inserted into the composition, with the time when the probe was inserted into the composition as the measurement start time (0 seconds). The carbon dioxide concentration (g / L) 90 seconds after the start of measurement was shown in the table as the "carbon dioxide concentration at 20-fold dilution".

[0091] <Texture of the foaming treatment agent composition> 0.2 g of the first agent and 1.0 g of the second agent described in the table were mixed with a finger for 5 seconds on a 7.5 cm × 7.5 cm plastic plate to prepare a foaming treatment agent composition. The texture of the obtained composition was evaluated in four grades according to the following criteria based on the appearance of the composition and the ease of dripping of the composition when the plastic plate was tilted at 45 degrees. (Evaluation criteria) 1: The appearance of the composition is liquid, and it drips immediately when the plastic plate is tilted at 45 degrees. Or, the appearance of the composition is in the shape of a mama ko or gel-like and does not seem to foam. 2: The appearance of the composition is slightly foamed, and it drips within 10 seconds when the plastic plate is tilted at 45 degrees. 3: The appearance of the composition is foamy. When the plastic plate is tilted at 45 degrees, it does not drip for 10 seconds, but dripping is observed when the time exceeds 10 seconds. 4: The appearance of the composition is foamy, and there is no dripping of the composition even when the plastic plate is tilted at 45 degrees.

[0092] <Foam volume of the foaming treatment agent composition> A hair tress with a mass of about 20 g and a length of 20 cm (made from the hair of Japanese women who have not undergone chemical treatment) was wetted with tap water and then washed with a plain shampoo having the following composition. The hair tress was not dried and was used for evaluation in a wet state. 0.2 g of the first agent and 1.0 g of the second agent described in the table were mixed in the hand for 5 seconds to prepare a foaming treatment agent composition. Then, the composition was applied to the wet hair tress and foamed by hand for 10 seconds. The foam volume at this time was scored on a 9-point scale in 0.5 increments from score 1 to 5, with the foam volume when 1.0 g of the second agent used in Example 1 alone was used as score "3". The higher the score, the more the foam volume, which means better results.
