Description

  The present invention relates to a hair styling material.

  Conventionally, as a general hair styling agent, a type that uses the film forming ability of a specific resin (hereinafter referred to as “resin type”) and a type that mainly uses the hair styling power of a solid wax (hereinafter referred to as “hair type”). "Solid wax type") is known.

  Resin-type hair styling is excellent in the hair setting effect and has a feeling of use with relatively little stickiness. On the other hand, since the surfaces of the hair are bonded to each other, the hand comb does not pass, and there is a drawback that the natural movement and the flow of the hair are lacking. On the other hand, the solid wax-type hair styling has a natural setting power, but has a drawback that the hair is sticky.

  Therefore, in resin-type hair styling with less stickiness, a resin (for example, an acrylic resin) that has excellent film-forming ability, forms a good film on each surface of hair, and can suppress adhesion between hairs. Resins) have been provided to solve the above drawbacks, but there is also a problem that the feel becomes hard. In addition, hair styling using the above acrylic resin has a problem that the setting effect is impaired when an oil component such as ester oil is blended for the purpose of improving gloss and feel.

  For example, it contains a film-forming substance (resin) and pantothenyl alcohol as a cosmetic for hair (ie, a hair styling agent) that is excellent in setting effect, suppresses poor touch such as stickiness, and gives natural luster. A cosmetic for hair is proposed (Patent Document 1). In this hair cosmetic, the film made of a film-forming substance is plasticized with pantothenyl alcohol to suppress poor hand feeling such as a feeling of hair stiffness.

  The pantothenyl alcohol used in the cosmetic for hair of Patent Document 1 can certainly plasticize the resin film and improve the feel of the hair, but as a result, the film softens and the setting effect is impaired. is there. These disadvantages are particularly noticeable in spray-type hair styling products.

JP 2001-354525 A

  The present invention is a resin-type hair styling composition, which maintains an excellent setting effect and can impart excellent gloss and feel to hair, and a spray-type hair styling containing the composition The purpose is to provide a fee.

  The hair styling composition of the present invention solves the above problems by including an acrylic resin alkanolamine and a hydrogenated rosin.

  In the hair styling composition of the present invention, in addition to selecting and adopting an acrylic resin alkanolamine excellent in the effect of improving a good setting effect, hair gloss and feel as a polymer (resin), These effects can be made to coexist at a high level by using a hydrogenated rosin that can further improve the gloss and feel of the hair without impairing the setting effect.

  In the said hairdressing composition, it is preferable that content of the said acrylic resin alkanolamine shall be 0.1-20 mass%, and content of hydrogenated rosin shall be 0.05-10 mass%.

  Moreover, the spray type hairdressing composition containing the said hairdressing composition of this invention is also included by this invention.

  According to the hair styling composition of the present invention, the gloss and feel of hair are improved while ensuring a high setting effect. Moreover, according to the spray-type hair styling composition of the present invention, the hair styling composition of the present invention can be more uniformly applied to the hair, so that the effect of improving the gloss and feel of the hair can be further extracted.

  Hereinafter, the present invention will be described in detail. In the hairdressing composition of the present invention, the polymer used for exhibiting the above effect is an acrylic resin alkanolamine.

  The acrylic resin alkanolamine is a polymer or copolymer obtained by polymerizing a monomer component containing (meth) acrylic acid as an essential component, and an amino alcohol [for example, 2-amino-2-methyl -1-propanol (AMP)] means a structure obtained by neutralization. Specifically, “Plus size” (L-9540B, L-9400, L-9480, L-9850, L-9909B, L-9700, etc. used in the examples) manufactured by Kyoyo Chemical Industry Co., Ltd., Osaka Organic Chemical Co., Ltd. “Aniset” manufactured by Kogyo Co., Ltd. (KB-1000, KB-100H, HS-3000, NF-1000, NF-2000, L-1000, AQ-2500, etc.) and the like can be mentioned.

  When using the above acryl resin alkanolamine, a polymer obtained by polymerizing the acrylic resin alkanolamine with a monomer component containing other acrylic acid as an essential component, that is, acrylic acid / methacrylic acid / 2-hydroxypropyl acrylate・ N, N-dimethylaminoethyl methacrylate, ethyl methacrylate, diacetone acrylamide, vinyl pyrrolidone copolymer and neutralized product thereof, t-butyl acrylate, ethyl acrylate, methacrylic acid copolymer and neutralized product thereof , Acrylic acid / acrylamide / ethyl acrylate copolymer and neutralized product thereof, acrylic acid octylamide / acrylic acid ester copolymer and neutralized product thereof, acrylic acid / methacrylic acid copolymer and neutralized product thereof, acrylic Acid octylamide, acrylic acid Mud propyl-butylaminoethyl methacrylate copolymers and the acrylic acids, such as neutralized product by polymerizing a monomer component containing as essential components comprising the polymer may be used in combination.

  The hydrogenated rosin is obtained by hydrogenating a double bond contained in abietic acid and its isomer in rosin. For example, “Pine Crystal KR-85” manufactured by Arakawa Chemical Industries, Ltd. can be used. .

  In the hairdressing composition of the present invention, the acrylic resin alkanolamine and hydrogenated rosin are dissolved or dispersed in a solvent. As the solvent, alcohols such as ethanol and isopropanol are usually used, and ethanol is particularly preferable.

  Furthermore, it is desirable that the hair styling composition of the present invention contains a nonionic surfactant. This nonionic surfactant can be used for the purpose of enhancing the detergency of a film formed on the hair surface by the acryl resin alkanolamine and suppressing the occurrence of flaking and the like. As the nonionic surfactant, for example, polyoxyethylene cetyl ether, polyoxyethylene oleyl ether, polyoxyethylene hydrogenated castor oil and the like are suitable.

  The hairdressing composition of the present invention has the form of a solution or a dispersion as described above. The content of the acrylic resin alkanolamine in this solution or dispersion is 0.1% by mass or more, more preferably 0.5% by mass or more, and 20% by mass or less, more preferably 10% by mass or less. It is desirable. If the content of the acrylic resin alkanolamine in the hairdressing composition is too small, the hairstyling property (setting effect) of the hairdressing composition may be insufficient. On the other hand, if the content of the acrylic resin alkanolamine in the hairdressing composition is too large, the hair tends to be sticky or stiff, and the acrylic resin alkanolamine accumulates in the hair and causes flaking that peels off in white scales. It may become.

  The content of the hydrogenated rosin in the hairdressing composition composition or dispersion is 0.05% by mass or more, more preferably 0.25% by mass or more, and 10% by mass or less, more preferably 5% by mass or less. It is desirable to be. If the content of the hydrogenated rosin in the hair styling composition is too small, the effect of imparting a gloss or good feel to the hair may be reduced. Conversely, if the content is too large, the hair may become stiff or The fingering may become worse.

  In addition, it is preferable that the content of the nonionic surfactant in the hairdressing composition composition or dispersion is, for example, 0.01 to 0.5% by mass. If the content of the nonionic surfactant is too low, the effect of adding the nonionic surfactant may not be ensured sufficiently. On the other hand, if the content is too high, the hair feels sticky and the holding effect of the setting effect decreases. There are things to do.

  In addition, the hair styling composition of the present invention may contain various additives as necessary within a range not impairing the effects of the present invention. Examples of such additives include hydrocarbon compounds (liquid paraffin, squalane, etc.), cationic surfactants (stearyl trimethyl ammonium chloride, cetyl trimethyl ammonium chloride, dicocoyl dimethyl ammonium chloride), anionic surfactants. (Sodium polyoxyethylene lauryl sulfate, sodium α-olefinate, etc.), amphoteric surfactants (betaine, etc.), oils (esters such as isopropyl myristate, isononanoyl isononate; vegetable oils such as hopa oil, avocado oil; Etc.), wetting agents (glycerin, propylene glycol, 1,3-butylene glycol, dipropylene glycol, polyethylene glycol, sorbitol, maltitol, pyrrolidone carboxylic acid, etc.), preservatives (methyl paraoxybenzoate) Propyl paraoxybenzoate, sodium benzoate, phenoxyethanol, etc.), chelating agents (ethylenediaminetetraacetic acid or its salt, diethylenetriaminepentaacetic acid or its salt, hydroxyethylethylenediaminetriacetic acid or its salt, hydroxyethanediphosphonic acid or its salt), A fragrance | flavor, a coloring agent, etc. are mentioned.

  The hairdressing composition of the present invention is not particularly limited with respect to its product form, but is preferably in the form of, for example, a spray-type hairdressing composition. The spray-type hair styling is obtained by filling an aerosol or a dispenser container with a base material obtained by using the hair styling composition of the present invention as a stock solution and further adding a propellant or the like. Thus, by setting it as the form of a spray type hair styling agent, since a hair styling composition can be apply | coated to hair more uniformly, the improvement effect of the gloss and feel of hair can be pulled out further. The propellant in the case of a spray-type hair styling agent is not particularly limited as long as it can be generally used for aerosol products. For example, liquefaction of various liquefied petroleum gas (LPG), dimethyl ether, isopentane, or a mixture thereof. Gas; compressed gas such as nitrogen gas and carbon dioxide gas; In general, the amount of the propellant used in the case of the spray-type hair styling is, for example, undiluted solution (hair styling composition) / propellant = 20/80 to 80/20 (mass ratio).

  Hereinafter, the present invention will be described in detail based on examples. However, the following examples are not intended to limit the present invention, and all modifications made without departing from the spirit of the preceding and following descriptions are included in the technical scope of the present invention. In the following examples and the like, the blending amount of each component is shown in% so that the entire hairdressing composition is 100%, all of which are% by mass, and in each table below Then, the display of% is omitted, and only the numerical value indicating the blending amount is displayed.
