Description

Hair styling agent composition

The present invention relates to a hair styling composition.

In the field of hair styling, in order to fix and maintain hair in a desired shape, various adhesive polymers or styling polymers that form a film are used.

For example, Patent Document 1 discloses a copolymer containing an ester monomer of an alcohol having 4 to 30 carbon atoms and (meth)acrylic acid, and a specific ester of polyoxyalkylene and (meth)acrylic acid Type monomer as a constituent monomer and has a cloud point. According to the description, the hair styling compound prepared with the copolymer forms a hydrophobic coating, and has excellent continuity of hair styling power. In addition, Patent Document 2 proposes a hair styling agent containing a polymer containing a monomer unit containing a side chain type poly(alkyleneoxy) substituent as a hair styling agent capable of improving hair volume. As such a polymer, a poly(nonaglycol methyl ether acrylate) homopolymer is disclosed in the examples.

In addition, when it is desired to improve the holding power of the styling of the hairstyle, the amount of the adhesive polymer or the styling polymer that forms a firm coating is generally increased to increase the adhesiveness of the polymer or the strength of the polymer coating. On the other hand, in hair styling in recent years, it is required to fix and maintain the hair in a desired shape, while maintaining a natural touch without making the hair hard or sticky.

However, in the case of using an adhesive polymer, there is a problem that if the holding power of the styling is to be improved, the stickiness is strongly expressed, and it is difficult to maintain the hair with a natural touch. On the other hand, in the case of using a polymer that forms a strong coating, although the stickiness is small, there is a problem that the hair is hard in most cases and the natural touch cannot be obtained, or Once the formed coating is damaged, the hair style cannot be maintained.

In this regard, for example, in Patent Document 3, as a hair styling agent excellent in the case of maintaining a hairstyle with a dry and refreshing texture without stickiness, it is proposed to use a copolymer of polyhydroxyethyl acrylate and methoxyethyl acrylate and a multicomponent A hair styling agent formulated with alcohol at a specific ratio.

The present invention provides a hair styling agent composition comprising the following components (A) and (B), and the mass ratio (B)/(A) of component (B) to component (A) is 0.03 or more and 1 or less;

(A) A polymer obtained by copolymerizing monomer components containing monomer (a-1) and monomer (a-2)

(b-1) Copolymer of hydroxyalkyl (meth)acrylate and alkoxyalkyl (meth)acrylate

(b-2) Copolymer of hydroxyalkyl (meth)acrylate, alkoxyalkyl (meth)acrylate, and dialkylamide of (meth)acrylate

According to a recent survey, in recent years, the requirements for three-dimensional or volumetric hair styles have been further changed to create a natural, dry and refreshing touch that does not apply anything after shampooing, and can be moderate during hair styling. The sense of the hair bundle makes the hair stand up from the root, and after the hair is set, a hair style with a fluffy curvature is formed instead of partially setting the root of the hair under the condition of unnatural hair bundle or gloss as before Hair styles that increase or only increase the volume of the hair bundle, and then require that the hairstyle be maintained over time.

However, in the hair styling of Patent Document 1 or 2, when the blending amount of the polymer and the like is controlled to the extent that the touch feeling after modification becomes good, it is impossible to create a sufficient fluffy three-dimensional feeling and volume feeling Even if the hair root can be temporarily raised, the continuity over time is not sufficient. In addition, in the case of giving sufficient three-dimensionality, volume, and good continuity over time, it is necessary to increase the amount of polymer, etc., and the hand movement is stronger during hair styling. The hair tress is also strong, and it becomes like a polymer coating on the hair The appearance or stickiness is strong, and it is difficult to call it a natural, dry and refreshing touch.

In addition, in the hair styling of Patent Document 3, even if the entire hair bundle can show a three-dimensional feeling or a volume feeling, it cannot create a curved hair style as a whole. In addition, when the amount of the polymer is increased until the spontaneous roots can be fully raised, the hand movement feeling is stronger during hair setting, and the hair bundle feeling is stronger after hair setting, as if there is a polymer on the hair The appearance of the film, the toughness of the hair becomes too strong, the hair feels hard, it is difficult to call it a natural, dry and refreshing touch. In addition, the hair styling of Patent Document 3 also has the following problem: when the amount of polymer and the like is controlled to the extent that the touch after modification becomes good, it is impossible to create a sufficient fluffy three-dimensional feeling and volume feeling Even if the hair root can be temporarily raised, the continuity over time is not sufficient.

Therefore, the present invention relates to a hair styling agent composition in which, even if the amount of the polymer is such that it has a natural appearance and natural hand touch after hair styling, the hair styling can be moderately adjusted during hair styling. The hair roots stand up, creating a natural look like a polymer film that does not exist on the hair after hair styling, a hair style with fluffy three-dimensionality and curvature, and can maintain the hair style over time.

The present inventors have found that: a copolymer of a specific (meth)acrylate-based monomer and a (meth)acrylate-based monomer containing an ethylene oxide group, and a hydroxyalkyl (meth)acrylate Although the specific copolymer of the monomer and the alkoxyalkyl (meth)acrylate monomer does not have adhesiveness on the hair when used separately for the hair styling agent, they should be used in combination at a specific ratio In some cases, the hair exhibits adhesion on the hair during application. On the other hand, after hair styling, a film that loses adhesion is formed on the hair, and a hair styling composition that meets all the above requirements can be obtained.
