Description

[Technical field]

[0001] The present invention relates to a hair cosmetic composition and a hair treatment method. [Background technology]

[0002] In recent years, hair cosmetics are increasingly expected to have a conditioning effect that can impart smoothness, softness, manageability, etc. to hair. Techniques for imparting smoothness, softness, manageability, etc. to hair by blending cationic polymers or anionic polymers have already been reported.

[0003] For example, Patent Document 1 describes that a hair treatment agent containing (A) a cationic polysaccharide, (B) a specific crosslinked cationic polymer, (C) a fatty acid or a salt thereof, and (D) a cationic surfactant not only prevents hair from becoming fuzzy while sleeping, but also suppresses stickiness during rinsing, imparts smoothness to the hair, and enables the manageability and smoothness of the hair to be maintained until the next time the hair is washed.

[0004] Patent Document 2 describes that a hair cleanser composition containing (A) an anionic surfactant, (B) a crosslinked cationic polymer, a hydrophobic cationized hydroxyethyl cellulose, and water is excellent in terms of ease of unraveling hair during rinsing, lack of tangling, lack of squeaky feeling, and rich feeling, and furthermore is capable of drying wet hair in a short time after washing.

[0005] Patent Document 3 describes a hair wash composition containing component (A): an anionic surfactant, component (B): a cationic polymer, component (C): a polymer containing a specific structural unit, and water, wherein the mass ratio ((B) / (C)) of the content of component (B) to the content of component (C) in the hair wash composition is within a specific range, which prevents hair from getting tangled and imparts smoothness and softness that are preferable in terms of manageability and feel to the hair.

[0007] In recent years, hair cosmetics have been given new functions such as suppressing hair curls and making hair manageable, but no technology has been established for controlling the shape of hair itself. Therefore, there is a demand for a function to bundle hair and give it a certain shape while fixing the shape, for example, a function to bundle and fix curled hair or other unruly hair into a straight shape or a neat wavy shape. The hair cosmetics in the above Patent Documents 1 to 3 have room for improvement in terms of their ability to fix the shape of hair. The present invention relates to a hair cosmetic composition and a hair treatment method having improved hair shape fixing power. [Means for solving the problem]

[0008] The present inventors have found that a hair cosmetic composition containing (A) an anionic polymer, (B) an anionic surfactant, (C) a cationic polymer having a cellulose skeleton, and (D) a cross-linked cationic vinyl polymer can improve the shape-fixing power of hair, and have completed the present invention.

[0009] That is, the present invention relates to the following [1] and [2]. [1] A hair cosmetic composition containing the following components (A) to (D): (A) Anionic polymer (B) Anionic surfactant (C) Cationic polymer having a cellulose skeleton (D) Crosslinked cationic vinyl polymer [2] A hair treatment method comprising the steps of applying the hair cosmetic composition according to [1] above to hair, and rinsing the hair to which the hair cosmetic composition has been applied with water. Effect of the Invention

[0010] According to the present invention, it is possible to provide a hair cosmetic composition and a hair treatment method having improved hair shape fixing power. [Brief description of the drawings]

[0011] [Figure 1] 1 is a diagram for explaining fixation of the hair shape, showing a photograph of a hair bundle hung with its upper end fixed, viewed from the front. In the figure, (a) shows an untreated evaluation hair bundle, and (b) shows the untreated evaluation hair bundle of (a) after being treated with the hair cosmetic composition of the present invention, straightened with a ring comb, and completely dried with a hair dryer. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] [Hair cosmetics] The hair cosmetic composition of the present invention contains the following components (A) to (D). (A) Anionic polymer (B) Anionic surfactant (C) Cationic polymer having a cellulose skeleton (D) Crosslinked cationic vinyl polymer In the present invention, "containing component X" is considered to be synonymous with "composed of component X."

[0013] The hair cosmetic composition of the present invention can improve the shape fixing power for fixing the shape of the bundled hair while tying hair into a certain shape, and therefore can be suitably applied, particularly when styling unruly hair such as curled hair into a straight or neat wavy shape, since it can reduce the time and effort required and can maintain the created shape for a long time. Fig. 1 is a diagram for explaining fixation of the hair shape, and shows a photograph of a hair bundle hung with its upper end fixed, viewed from the front. In Fig. 1, (a) shows an untreated evaluation hair bundle, and (b) shows the untreated evaluation hair bundle of (a) after being treated with the hair cosmetic composition of the present invention, straightened with a ring comb, and completely dried with a hair dryer. That is, in the present invention, "hair shape fixing power" refers to the power to strongly fix the shape of, for example, curled hair as shown in Fig. 1(a) by bundling it into a straight shape as shown in Fig. 1(b), and maintaining the shape even after drying. Note that in the present invention, "fixing the hair shape" refers to a state in which hairs are bound together and the hair bundle is fixed in a certain shape, which is different from "tidy hair" which refers to a state in which the hair line is beautiful and not disturbed from the top to the tip.

[0014] The reason why the hair cosmetic composition of the present invention having the above-mentioned composition exhibits the effects of the present invention is presumed to be as follows. The hair cosmetic composition of the present invention contains an anionic polymer as component (A), an anionic surfactant as component (B), a cationic polymer having a cellulose skeleton as component (C), and a crosslinked cationic vinyl polymer as component (D). Component (A), which is an anionic polymer, and component (B), which is an anionic surfactant, can form a complex gel through interaction with components (C) and (D), which are cationic polymers. It is believed that when hair to which the hair cosmetic composition of the present invention has been applied is rinsed, excess anionic surfactant component (B) is washed away, the complex gel precipitates on the hair surface, and an adhesive complex gel film is formed on the hair surface. It is believed that when a complex gel film having adhesive properties is formed on hair, the complex gel film binds and supports the individual hairs together, thereby fixing the shape of the hair. Here, component (C) has excellent adhesion to hair, so it is easily absorbed evenly throughout the hair, and component (D) has excellent water retention properties, so it can increase the total amount of complex gel formed. The action of both components makes it possible for a large amount of gel to be absorbed by the hair. From the above, it is believed that the hair cosmetic composition of the present invention, by combining components (A) to (D), is able to form a film with good binding power uniformly over the entire hair, thereby bundling the hair to give it a certain shape, while improving the shape-fixing power for fixing the shape of the bound hair.

[0015] Examples of the hair cosmetic of the present invention include hair cleansing agents such as hair shampoos, hair rinses, hair conditioners, hair treatments, hair packs, hair styling agents, etc. Among these, from the viewpoint of further exerting the effects of the present invention, those used after washing hair are preferred, and those used after being applied to the hair and rinsing are more preferred. From such a viewpoint, the hair cosmetic of the present invention is preferably a hair rinse, hair conditioner, hair treatment, hair pack, or hair styling agent. The hair cosmetic composition of the present invention may be in any form, such as a liquid, foam, paste, cream, etc. Among these, from the viewpoint of ease of use, etc., the liquid, paste, or cream form is preferred, and the liquid form is more preferred.

[0016] <Component (A): Anionic polymer> The hair cosmetic composition of the present invention contains an anionic polymer as component (A). Examples of the anionic polymer include vinyl polymers having a carboxy group or a sulfonic acid group as an anionic group. From the viewpoint of versatility, vinyl polymers having a carboxy group are preferred, and examples thereof include vinyl polymers containing structural units derived from crotonic acid, maleic acid, maleic acid monoester, itaconic acid, or (meth)acrylic acid.

Therefore, the shape fixing power of hair can be improved more in an aqueous medium by interaction with components (C) and (D) than a polymer containing alkyl methacrylate, which is less hydrophilic than acrylic acid, as a monomer constituent unit. The polymer of component (A) is preferably a crosslinked type. When component (A) is a crosslinked polymer, it has a high effect of improving the water retention of hair and can further improve the shape fixing power of hair. From the viewpoint of further improving the power to fix the shape of hair, component (A) preferably contains at least one selected from crosslinked polyacrylic acid and (acrylates / alkyl acrylate (C10-30)) crosspolymer, more preferably at least one selected from crosslinked polyacrylic acid and (acrylates / alkyl acrylate (C10-30)) crosspolymer, and even more preferably crosslinked polyacrylic acid.

[0017] Preferred crosslinked polyacrylic acids are carboxyvinyl polymers, or carbomers as they are known by the INCI name, which are polymers of acrylic acid crosslinked with pentaerythritol allyl ether, sucrose allyl ether or propylene allyl ether. Component (A) is preferably a vinyl polymer having a carboxy group as an anionic group, and forms a complex gel by interacting with components (C) and (D), which are cationic polymers having cationic properties. The complex gel has the effect of improving the water retention of hair and the effect of binding hairs together, thereby improving the shape fixing power of hair. (Acrylates / C10-30 alkyl acrylate) crosspolymer is a copolymer of one or more monomers consisting of acrylic acid, methacrylic acid, or their simple esters and alkyl acrylate (C10-30) crosslinked with allyl ether of sucrose or allyl ether of pentaerythritol, and its INCI name is Acrylates / C10-30 Alkyl Acrylate Cross Polymer.

Next, 0.2 g of a hair cosmetic composition having the composition shown in each Example and Comparative Example was applied to the hair bundle and allowed to blend for 1 minute. Next, the hair bundle to which the hair cosmetic composition was applied was rinsed with warm water (35-40°C) for 30 seconds. After that, the hair bundle was straightened with a ring comb, towel-dried, and completely dried with a dryer equipped with a diffuser to obtain hair bundles for evaluation. The length of the hair bundle obtained for evaluation and the bundle width at a point 20 cm from the root of the hair bundle were measured, and the hair shape fixing power was evaluated. The fixing power in the width direction of the hair bundle was evaluated by the bundle width (cm). The fixing power in the length direction of the hair bundle was evaluated by Δ length (cm) = (length of the hair bundle when stretched before treatment) - (length of the hair bundle after treatment). The smaller the bundle width and Δ length, the better the hair bundle shape fixing power. Here, "the length of the hair bundle when stretched before processing" refers to the length of the curly hair bundle before processing when it is lightly stretched by hand to straighten the curled hair bundle.
