Description

  The present invention relates to an aerosol composition for hair. More specifically, when the solid content is dissolved in the liquid phase of the aerosol composition and sprayed in the form of a mist, the spray particles can be finely adhered and deposited evenly on the hair, and not dissolved in the liquefied gas. The present invention relates to an aerosol composition for hair, characterized in that the state of adhesion to hair can be adjusted by a combination with a solid content.

  Conventionally, a method of directly implanting hair on the head is known as a method of thickening the thin hair portion of the head. However, since such a method requires specialized knowledge for the treatment, there is a problem that a treatment by an expert is required, and the user's time and money are heavy. Therefore, aerosol products have been developed that are used by being sprayed onto a portion where hair is reduced so that the user can easily use the method.

  For example, there are the following Patent Documents 1 to 3 as spray-type aerosol compositions for the hair that thicken the hair and relieve the feeling of thinning hair. The basic composition common to these patent documents is: a) a solid content not dissolved in a liquefied gas such as talc, b) a colorant such as carbon black, c) a resin for adhering the insoluble solid content and the colorant to the hair. D) volatile solvents such as ethanol; e) propellants such as liquefied petroleum gas for spraying.

  However, all of the aerosol compositions for hair of Patent Documents 1 to 3 disclose a technique for attaching an insoluble solid and a colorant to hair with a resin in order to thicken the hair. In order to feel it, it is necessary to mix insoluble solids and colorants in a large amount of about 10% by weight. As a result, insoluble solids and colorants start to settle during spraying, and thus there is a problem that it is difficult to spray with a uniform composition and the hair becomes non-uniform in thickness. In addition, there is a problem that the injection hole of the injection button and the stem hole of the aerosol valve are likely to be clogged.

  In addition, Patent Documents 1 and 2 describe that a uniform spray composition can be obtained by uniformly dispersing an insoluble solid and a colorant in a liquid phase by blending a specific surfactant. In general, when a surfactant is blended, the drying property tends to deteriorate, so that there is a problem that the wet state is maintained and the finish after spraying is deteriorated. Patent Document 3 describes that blending a large amount of the propellant as 99 to 70% by weight speeds up drying of the spray particles and reduces the decrease in thickness formed by adhering to the hair. As a dispersant for the colorant, a surfactant is used in the same manner as in Patent Documents 1 and 2, and there is a problem that the drying property is deteriorated.

  The aerosol composition for hair of the present invention has been made in view of the above-described conventional problems, and it is possible to spray a part of the thickening component in a mist shape and easily adjust the size of the sprayed particles. It can easily adjust the finish of volume, gloss, color tone, etc., easily adheres evenly to the hair, makes the hair evenly thick evenly, and has excellent powder dispersibility, propellant An object of the present invention is to provide an aerosol composition for hair that has a small change in concentration, can prevent clogging at injection holes and stem holes, and has excellent drying properties.

  An aerosol composition for hair according to the present invention contains a solid content that does not dissolve in a liquefied gas, a solid content that dissolves in a liquefied gas, an adhesive, a solvent, and a liquefied gas, The amount of solids dissolved in the gas is 0.5 to 10% by weight, the amount of the liquefied gas is 60 to 90% by weight, and the solids dissolved in the liquefied gas is the aerosol composition. It is characterized by being dissolved in the liquid phase of the product.

  Moreover, it is preferable that the solid content which melt | dissolves in the said liquefied gas is a higher alcohol.

  It is preferable that the compounding quantity of the solid content which does not melt | dissolve in the said liquefied gas is 0.5 to 7 weight%. It is preferable that the compounding ratio of the solid content not dissolved in the liquefied gas and the solid content dissolved in the liquefied gas is 75/25 to 20/80. Preferably, the liquefied gas contains dimethyl ether, or the liquefied gas is dimethyl ether.

  According to the aerosol composition for hair according to the present invention, a part of the thickening component can be dissolved in the liquid phase of the aerosol composition and sprayed in the form of a mist, and the size of the spray particles can be easily adjusted. It can easily adjust the finish of volume, gloss, color tone, etc., easily adheres evenly to the hair, makes the hair evenly thick evenly, and has excellent powder dispersibility, propellant Therefore, it is possible to obtain an aerosol composition for hair having excellent drying properties.

  The aerosol composition for hair of the present invention comprises a solid content in which the aerosol composition does not dissolve in the liquefied gas, a solid content that dissolves in the liquefied gas, an adhesive, a solvent, and a liquefied gas. The amount of solids dissolved in the liquefied gas is 0.5 to 10% by weight, the amount of the liquefied gas is 60 to 90% by weight, and the solid content dissolved in the liquefied gas is the aerosol composition. It is characterized by being dissolved in the liquid phase.

  The solid content that does not dissolve in the liquefied gas has some of the components that thicken the hair, such as talc, carbon black, calamine, gunjo, yellow iron oxide, black iron oxide, zinc oxide, magnesium oxide, titanium oxide, calcium carbonate , Mica titanium, bentonite, kaolin, silicic anhydride, magnesium silicate, aluminum silicate, mica, risol rubin BCA (red 202), lake red C (red 203), lake red CBA (red 204), resol red (Red 205), Risor Red CA (Red 206), Risor Red BA (Red 207), Risor Red SR (Red 208), Brillant Lake Red R (Red 219), Deep Maroon (Red 220) , Toluidine Red (Red 221), Permanentre (Red 228), Permanent Orange (Daidai 201), Bench Gin Orange G (Daidai 204), Bench Gin Yellow G (Yellow 205), Brilliant Fast Scarlet (Red 404), Permanent Red F5R ( Red No. 405), Hansa Orange (Dai Dai No. 401), Hansa Yellow (Yellow No. 401), Phthalocyanine Blue (Blue No. 404), etc. are selected as appropriate according to the color of the hair.

  The blending amount of the insoluble solid content is preferably 0.5 to 7% by weight, more preferably 1 to 5% by weight in the aerosol composition. When the amount of insoluble solids is less than 0.5% by weight, the hair tends to be thicker, and when it is more than 7% by weight, the insoluble solids settle more quickly, resulting in a concentration difference during jetting. It tends to be difficult to inject easily with a uniform composition. Moreover, it tends to become clogged easily with the injection hole of the injection button and the stem hole of the aerosol valve.

  The size of the insoluble solid content is preferably 0.5 to 15 μm, more preferably 1 to 10 μm. If the insoluble solid content is smaller than 0.5 μm, it will tend to agglomerate when left standing for a long period of time, and even if the aerosol composition is stirred by shaking the container, the insoluble solid content is difficult to disperse uniformly. If it is larger than 15 μm, it tends to be clogged with an injection button or an aerosol valve.

  The solid content that dissolves in the liquefied gas is a part of the component that thickens the hair, and is dissolved in the liquid phase of the aerosol composition in the aerosol container, thereby slowing the sedimentation of the insoluble solid and making the dispersibility. There is an action to improve. Further, when sprayed to the outside, the dissolved solids are uniformly attached to the hair as the spray particles are made finer, and precipitate in this state to have an effect of making the hair evenly thick. Furthermore, since the dissolved solid matter adheres to the hair in a dissolved state, it covers the surface of the hair and precipitates white, and the insoluble solid matter adheres to the upper surface, so the color of the powder remains unchanged regardless of the color of the hair. Has the effect of coloring. Examples of the dissolved solid content include solid higher alcohols such as lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, aralkyl alcohol, behenyl alcohol, and lanolin alcohol, lauric acid, myristic acid, palmitic acid, stearic acid, and behenic acid. Solid hydrocarbons such as solid fatty acids, petrolatum, paraffin, beeswax, carnauba wax, candelilla wax, beeswax, microcrystalline wax, polar wax, synthetic wax, paraffin wax, jojoba wax, polyethylene wax, lanolin, lanolin acetate, etc. Examples thereof include waxes, 2,4,6-triisopropyl-1,3,5-trioxane, and the like. In particular, it is preferable to use a higher alcohol having 14 to 18 carbon atoms because it is excellent in solubility in liquefied gas and easily obtains an action of thickening hair.

  The amount of the dissolved solid content is preferably 0.5 to 10% by weight, more preferably 1 to 5% by weight in the aerosol composition. If the dissolved solid content is less than 0.5% by weight, the effect of thickening the hair is difficult to obtain, and the drying property tends to deteriorate, and if it is more than 10% by weight, the jet particles become large. It tends to be easy and the thickness of the hair tends to be uneven.

  The adhering agent has an action of adhering insoluble solids to the hair and maintaining the state, for example, N-methacryloyloxyethyl N, N-dimethylammonium α-N-methylcarboxybetaine / methacrylic acid alkyl ester copolymer Amphoteric acrylic resins such as, crotonic acid-vinyl acetate-neodecanoic acid copolymer, polyurethane, dialkylaminoethyl (meth) acrylate- (meth) acrylic acid alkyl ester copolymer, octylamide acrylate-hydroxypropyl acrylate -Butylaminoethyl methacrylate copolymer, vinylpyrrolidone-vinyl acetate copolymer, hydroxyethyl acrylate-butyl acrylate-methoxyethyl acrylate copolymer, alkanolamine acrylate, alkyl acrylate ester-meta Alkylic acid alkyl ester-diacetone acrylamide-methacrylic acid copolymer, vinylpyrrolidone-N, N-dimethylaminoethyl methacrylic acid copolymer sulfate, hydroxyethyl cellulose-dimethyl diallylammonium chloride, alkyl acrylate copolymer emulsion, acrylic Examples thereof include acid alkyl-styrene copolymer emulsions. In addition, you may use what mix | blended colored powders, such as carbon black, with the said adhesive agent.

  The amount of the adhesive (resin solid content) is 0.1 to 5% by weight, more preferably 0.5 to 3% by weight in the aerosol composition. When the amount of the adhering agent is less than 0.1% by weight, the effect of adhering the insoluble solid content and the dissolved solid content after precipitation to the hair is insufficient, and the solid content tends to peel off easily. When the amount is more than% by weight, it tends to be clogged with the injection hole of the injection button or the stem hole of the aerosol valve.

  In the aerosol container, the solvent acts as a solvent for the adhering agent and dissolved solid content together with the liquefied gas. When sprayed, the solvent is finely divided and uniformly adhered to the hair and dried to precipitate the dissolved solid content. Examples of the solvent include monohydric alcohols having 2 to 3 carbon atoms such as ethanol and isopropanol.

  The blending amount of the solvent is preferably 3 to 30% by weight, more preferably 5 to 25% by weight in the aerosol composition. When the amount of the solvent is less than 3% by weight, precipitation of dissolved solids tends to be too fast and it tends to be difficult to uniformly adhere to the hair, and when it exceeds 30% by weight, it adheres to the hair. It takes a long time for the sprayed material to dry, and it tends to flow during drying and tends to cause unevenness.

  The liquefied gas is a liquid in the aerosol container, and acts as an adhesive and a solvent for dissolved solids together with the solvent. Moreover, when it sprays outside, it vaporizes, and there exists an effect | action which makes a propellant fine mist and adheres to hair evenly. Furthermore, it has the effect | action which cools a projectile and makes it easy to precipitate a melt | dissolution solid content. Examples of the liquefied gas include dimethyl ether, liquefied petroleum gas (propane, normal butane, isobutane and mixtures thereof), and a mixture of dimethyl ether and liquefied petroleum gas. In particular, it is preferable to use liquefied gas containing 50% by weight or more of dimethyl ether or dimethyl ether from the viewpoint of excellent solubility of the adhesive.

  The blending amount of the liquefied gas is preferably 60 to 90% by weight, more preferably 65 to 85% by weight in the aerosol composition. When the blended amount of the liquefied gas is less than 60% by weight, the sprayed particles tend to be coarse, difficult to adhere evenly to the hair, and tend to be difficult to dry, and when more than 90% by weight, the ejected particles Tends to bounce off and scatter easily even when sprayed toward the hair. In addition, it is preferable that the magnitude | size (average particle diameter) of a spray particle is 5-30 micrometers, Furthermore, it is 7-20 micrometers.

  In addition, the aerosol composition for hair of the present invention can contain a liquid oil, a dye, an active ingredient, a surfactant, and the like within the range not inhibiting the effects of the present invention in addition to the essential components described above. .

  When mix | blending the said liquid oil component, it is preferable that it is 0.1 to 10 weight%, Furthermore, it is 0.5 to 5 weight%. When the blending amount of the liquid oil is less than 0.1% by weight, the blending effect of the liquid oil tends to be insufficient, and when it exceeds 10% by weight, the drying property tends to be deteriorated.

  The dye is used for dyeing the hair to be the same color as the deposit. For example, Amaranth (Red No. 2), Erythrosin (Red No. 3), New Coxin (Red No. 102), Phloxine B (Red 104) No.), Rose Bengal (Red No. 105), Acid Red (Red No. 106), Tartrazine (Yellow No. 4), Sunset Yellow (Yellow No. 5), Fast Green (Green No. 3), Brilliant Blue FCF (Blue No. 1) ), Indigo Carmine (Blue No. 2), Resor Rubin B (Red No. 201), Fast Acid Magenta (Red No. 227), Eosin YS (Red No. 230), Phloxine BK (Red No. 231), Rose Bencar K (Red No. 232), Orange II (daidai color 205), erythrosin yellow NA (daidai color 207), uranin (yellow 202 ), Quinoline Yellow WS (Yellow No. 203), Alizanin Cyanine Green F (Green No. 201), Pyranine Conch (Green No. 204), Light Green SF Yellow (Green No. 205), Patent Blue NA (Blue No. 202), Patent Blue (Blue No. 203), Alphazurin FG (Blue No. 205), Resorcin Brown (Brown No. 201), Violamine R (Red No. 401), Pon So 3R (Red No. 502), Pon So (Red No. 503), Pon So SX (Red 504), Fast Red S (Red 506), Orange I (Daidai 402), Polar Yellow 5G (Yellow 402), Naphthol Yellow S (Yellow 403), Methanil Yellow (Yellow 406), Fast Light Yellow 3G (Yellow 407), Naphthol Green B (Green 401), Gi Acid dyes such as Nea Green B (Green No. 402), Alizurol Purple (Purple No. 401), Naphthol Blue Black (Black No. 401), Bases such as Rhodamine B (Red No. 213), Rhodamine B Acetate (Red No. 214) Dyes, rhodamine B acetate (red 215), tetrachlorotetrabromofluorescein (red 218), Sudan III (red 225), jodofluorescein (daidai 206), fluorescein (yellow 201), quinoline yellow SS (Yellow 204), quinizarin green SS (green 202), arizurin purple SS (purple 201), medicinal scarlet (red 501), oil red XO (red 505), orange SS (approx. 403) ), Yellow AB (Yellow 404), Yellow O (No. 405 yellow), oil-soluble dyes include Stan Blue B (Blue No. 403), tetrabromofluorescein (Red No. 223), oil dye such as Dibromofluorescein (orange No. 201), and the like.

  When mix | blending the said dye, it is preferable that it is 0.01-5 weight%, Furthermore, 0.05-3 weight%. When the amount of the dye is less than 0.01% by weight, the dyeing effect tends to be insufficient, and when the difference between the color of the deposit and the color of the hair before treatment is large, There is a difference in the color of the hair, causing a sense of incongruity. On the other hand, when it exceeds 5% by weight, it becomes difficult to mix, for example, it becomes difficult to dissolve in a solvent.
