Description

  The present invention relates to a hairdressing composition.

  In the field of hair styling, various adhesive polymers and set polymers that form films are used to fix and maintain the hair in the desired shape.

  For example, Patent Document 1 contains an ester monomer of an alcohol having 4 to 30 carbon atoms and (meth) acrylic acid and an ester monomer of a specific polyoxyalkylene group and (meth) acrylic acid as constituent monomers. Copolymers having a cloud point are disclosed. It is described that a hairdressing composition blended with this copolymer forms a hydrophobic film and is excellent in sustainability of hairdressing power. Patent Document 2 proposes a hairdressing composition containing a polymer containing a monomer unit containing a pendant poly (alkyleneoxy) substituent as a hairdressing composition that can improve the hair volume. As such a polymer, poly (nonaethylene glycol methyl ether acrylate) homopolymer is disclosed in the examples.

  By the way, when it is desired to increase the set holding power of the hairstyle, it is common to increase the compounding amount of the adhesive polymer or the polymer for the set that forms a strong film, thereby increasing the adhesiveness of the polymer and the strength of the polymer film. On the other hand, recent hair styling products are required to fix and maintain the hair in the desired shape, and at the same time maintain the natural feel without making the hair stiff or sticky.

  However, when the adhesive polymer is used, there is a problem that stickiness is strongly expressed when trying to increase the set holding power, and it becomes difficult to keep the hair in a natural feel. On the other hand, when a polymer that forms a strong film is used, there is little stickiness, but the hair is often stiff and a natural feel cannot be obtained, and once the formed film is damaged, the hairstyle There was a problem that could not be maintained.

  On the other hand, for example, in Patent Document 3, as a hair styling agent that is excellent in maintaining a style with a non-sticky and smooth texture, a copolymer of hydroxyethyl acrylate and methoxyethyl acrylate and a polyhydric alcohol are used. Hairdressing formulas formulated at specific ratios have been proposed.

  In recent years, the research required for hairstyles with a three-dimensional feel and volume has changed further in recent years, and the root part of the hair is raised with an unnatural feeling of bunch and gloss as before, or simply It is not a hairstyle that increases the volume of the hair bundle, but it is a natural and smooth feel that does not have anything after washing, but at the time of hair styling, the hair can be raised from the root with an appropriate sense of bundle, In addition, it has been found that after hair styling, the hair style can be made soft and round, and the hair style is required to be maintained over time.

  However, in the hairdressing materials of Patent Documents 1 and 2, when the blending amount of the polymer or the like is suppressed to such an extent that the feeling after finishing is good, a sufficiently soft three-dimensional feeling and volume cannot be made, and temporarily Even if the root could be started up, the sustainability over time was insufficient. In addition, when giving sufficient three-dimensional feeling and volume, and giving good sustainability over time, it is necessary to increase the blending amount of polymers etc., the feeling of hand movement during hair styling is strong, and a feeling of bundle after hair styling It has a strong appearance and a sticky feel as if a polymer film is present on the hair, and it is difficult to say that the finish is natural and smooth.

  Further, with the hair styling material of Patent Document 3, even if a three-dimensional feeling and volume can be produced on the entire hair bundle, it is not possible to create a rounded style. In addition, when the amount of the polymer is increased until it can be sufficiently started up from the root, the feeling of hand movement is strong at the time of styling, the sense of bundle is strong after styling, and the polymer film appears on the hair. Appearance is too strong, the hair is too stiff and the hair feels stiff, and it is hard to say that the finish is natural and smooth. In addition, the hair styling of Patent Document 3 is also unable to create a sufficiently soft three-dimensional feeling and volume when the blending amount of the polymer or the like is suppressed to such an extent that the feeling after finishing is good, and temporarily, Even if the root can be started, there is a problem that the sustainability with time is insufficient.

  Therefore, the present invention can start up from the root with an appropriate bunch feeling at the time of hairdressing even if the amount of the polymer blends to a natural appearance and natural touch after hairdressing, and the polymer coating is applied to the hair after hairdressing. The present invention relates to a hair styling composition capable of producing a style that is soft and three-dimensional and round with a natural appearance that does not exist, and that can maintain the style over time.

  The present inventors include a copolymer of a specific (meth) acrylate monomer and an ethylene oxide group-containing (meth) acrylate monomer, a (meth) acrylic acid hydroxyalkyl ester monomer, and a (meth) acrylic acid alkoxyalkyl ester monomer. When used alone as a hair styling agent, each of the specific copolymers contains no adhesiveness on the hair, but when these are used in combination at a specific ratio, they adhere to the hair when applied. On the other hand, it has been found that a hair styling composition satisfying all of the above requirements can be obtained by forming a film that loses adhesiveness on the hair after hair styling.

The present invention provides a hairdressing composition comprising the following components (A) and (B), wherein the mass ratio (B) / (A) of the component (B) to the component (A) is 0.03 or more and 1 or less. It is to provide.

Examples 1-12, Comparative Examples 1-5
The hairdressing composition shown in Tables 1 and 2 was prepared, put in a mist sprayer (head part: YSR manufactured by Yoshino Seisakusho), and evaluated as follows. The results are also shown in Tables 1 and 2.

<Evaluation of ease of shaping near the root of hair bundle during hairdressing>
To dry hair of Asian hair and shortcut hair wigs, spray 1.0g of hair cosmetics of each prescription on the whole wig, put your fingers in the roots, and create a soft feeling while passing through the fingers to raise the roots The hair was trimmed to create a three-dimensional feeling while holding the hair on the surface. At this time, from the viewpoint of ease of shaping near the root of the hair bundle during hairdressing, the seven panelists were asked whether they were “easy to shape”, “neither” or “difficult to shape”. It was made to choose alternatively. The number of panelists who answered “easy to shape” / “neither” or “difficult to shape” is shown in order.

<No stickiness during hair styling>
The same operation as the method for evaluating the ease of shaping was performed. At this time, seven panelists evaluated the feel of hair from the viewpoint of lack of stickiness. One of the choices was “I did not feel stickiness” / “I could say neither” / “I felt stickiness”. The number of panelists who answered “I did not feel sticky” / “I could say neither” / “I felt sticky” is shown in order.

<Soft 3D and roundness immediately after finishing>
The same operation as the method for evaluating the ease of shaping was performed, and from the viewpoint of whether a style with a fluffy feeling immediately after hair styling was made, 7 panelists said, “A style that has a soft three-dimensionality and roundness. It was alternatively selected from "I was able to do it" / "I can't say either" / "I couldn't create a style with a soft 3D effect and roundness". The number of panelists who answered, “I was able to create a style with a soft three-dimensional effect and roundness” / “I can't say either” / “I couldn't make a style with a soft three-dimensional effect and roundness.”

<No polymer presence right after finishing>
Using the wig after creating a soft style, seven panelists evaluated the feel of the hair. One of “no polymer presence on the hair” / “neither” or “the polymer presence on the hair” was selected. The number of panelists who answered, “There is no polymer presence on the hair” / “None” / “There is a polymer presence on the hair” is shown in order.

<Feeling of hair bundles just after finishing>
Since the hair bundle after styling has a feeling of dispersion, it seems that the polymer film has a natural appearance such that it does not exist on the hair. Therefore, evaluation was performed using the feeling of dispersion of the hair bundle. Using the wig after creating a fluffy style, 7 panelists were either "I feel a sense of hair bundles" / "I can't say either" / "I don't feel a sense of hair bundles" It was made to choose alternatively. The number of panelists who answered, “There is a sense of dispersal of hair bundles” / “I cannot say either” / “I do not feel discomfort of hair bundles” is shown in order.

<Soft feeling after 10 minutes>
Using the wig after creating a fluffy style, 7 panelists “feel soft and fluffy” from the viewpoint of whether the fluffy style remains when left for 10 minutes. The choice was either “I can't say either” or “No soft feeling”. The number of panelists who answered “I feel soft” / “I can't say either” / “I don't feel soft” is shown in order.
