Description

  The present invention relates to a styling aerosol composition comprising a cationic polymer composition containing a specific copolymer, a stock solution containing a polyhydric alcohol, and a liquefied gas.

  As a conventional styling aerosol composition, a stock solution in which a styling component such as an amphoteric polymer, a cationic polymer or an anionic polymer is mixed with a solvent such as ethanol or water is filled in an aerosol container together with a liquefied gas such as liquefied petroleum gas. Things are known.

  As an index for evaluating the performance of a styling agent, a curl retention force (Curl Retention) and a set force (Stiffness) are generally known. Conventional styling aerosol compositions have been adjusted by methods such as using a polymer with a large molecular weight (high degree of polymerization) or increasing the amount of polymer blended when it is desired to increase curl retention. As the curl retention increases, the hair finishes harder, so that once dried, it is difficult to correct, and when the hair is disturbed, it is difficult to re-hair.

  In order to give flexibility to the finish, oily components such as silicone oil, ester oil and mineral oil and plasticizers such as surfactants were blended, but curl retention and setting power were improved by blending the plasticizer. There was a problem that both decreased.

  As means for solving such a problem, a cosmetic for hair comprising an oil-in-water emulsion and a polymer resin compound prepared by a specific method has been disclosed (for example, see Patent Document 1). Patent Document 1 describes that a cosmetic for hair can be obtained with little reduction in set power and set retention due to plasticity of oil, and less reduction in smoothness due to polymer compounds. A hair mousse, a hair cream, and a hair spray containing a polyol are disclosed. However, when the cationic resin (vinyl pyrrolidone / dimethylaminoethyl methacrylate copolymer cationized product; trade names Guff Coat 755, Guff Coat 734) used in Patent Document 1 is blended with a polyhydric alcohol to form a styling agent, the sticky feeling However, there is a problem that the feeling of use is lowered, such as that the strength of the toner is increased, the combing path is poor, and dust and dust are likely to adhere.

  Moreover, the foam-like hairdressing agent which consists of the undiluted | stock solution containing a specific surfactant, a polyhydric alcohol, and the fixing polymer for hair, and a propellant is known (for example, refer patent document 2). It is described that the hair styling material of Patent Document 2 can be freely styled without firming the hair and is excellent in hair styling power over time. However, a cationic polymer (vinyl pyrrolidone / N, N-dimethylaminoethyl methacrylic acid copolymer diethyl sulfate salt; trade name HC polymer 2L) used in Patent Document 2 is blended with a polyhydric alcohol. When used as a styling agent, there is a problem that the feeling of sticking is increased, the combing is not good, and dust, dust, etc. are easily attached, and the feeling of use is lowered.

  Therefore, at present, there is still no styling aerosol composition that can adjust the setting force while maintaining the curl holding force and has no stickiness.

Japanese Patent Laid-Open No. 9-255534 JP 2000-204025 A

  When applied to the hair, the present invention forms a stretchable film that enables re-styling, can be adjusted to the desired setting force while maintaining the curl retention, and becomes white when the film is dry. An object of the present invention is to provide an aerosol composition for styling capable of suppressing flaking that precipitates and having no stickiness.

  The present invention relates to a cationic polymer composition containing vinylpyrrolidone / methacrylamide / vinylimidazole / methylvinylimidazolium methylsulfate copolymer and 10 to 500 parts by weight of polyhydric alcohol with respect to 100 parts by weight of the copolymer. The present invention relates to a styling aerosol composition comprising a stock solution containing liquefied gas and a liquefied gas.

  The blending amount of the copolymer is preferably 0.2 to 12% by weight in the stock solution, and the blending amount of the polyhydric alcohol is preferably 0.1 to 30% by weight in the stock solution.

  The polyhydric alcohol is preferably a trivalent alcohol.

  The polyhydric alcohol is preferably glycerin or panthenol.

  The present invention provides a styling aerosol composition comprising a cationic polymer composition containing a specific copolymer and a stock solution and a liquefied gas containing a polyhydric alcohol in a specific ratio, so that it can be stretched (restored) when applied to the hair. Can be adjusted to the desired setting force while maintaining curl retention, and suppresses flaking that precipitates white when the film dries. It is possible to provide an aerosol composition for styling that can be applied and has no stickiness.

  The present invention relates to a cationic polymer composition containing vinylpyrrolidone / methacrylamide / vinylimidazole / methylvinylimidazolium methylsulfate copolymer and 10 to 500 parts by weight of polyhydric alcohol with respect to 100 parts by weight of the copolymer. The present invention relates to a styling aerosol composition comprising a stock solution containing liquefied gas and a liquefied gas.

  The aerosol composition for styling of the present invention can be adjusted to a desired setting force while maintaining the curl holding force, and can be suitably used for styling hair.

  Here, the curl retention force means that the styling agent is applied and dried in a state where the hair bundle is fixed to the curler, the hair bundle removed from the curler is hung in a test chamber having a constant temperature and humidity, and the hair is held after a predetermined time. The length of the bundle is measured and calculated from the measured value. The set force is a styling agent applied to the hair bundle and dried, and the hair bundle is bent by applying a load from the side of the hair bundle. It is obtained by measuring the force required for this.

  Vinylpyrrolidone / methacrylamide / vinylimidazole / methylvinylimidazolium methylsulfate copolymer is a cationic polymer used as a styling component to form a film on the hair and maintain the set shape.

  Although it does not specifically limit as a cationic polymer composition containing the said copolymer, The composition which mix | blended water with the said copolymer can be mention | raise | lifted.

  The content of the copolymer in the cationic polymer composition is preferably 10 to 40% by weight, and more preferably 15 to 30% by weight. When the copolymer is less than 10% by weight, the amount of the cationic polymer composition to be added in order to obtain a desired effect tends to decrease, and the amount of other components that can be added tends to decrease. The viscosity of the cationic polymer composition tends to be high and difficult to handle.

  The amount of the cationic polymer composition is preferably 2 to 30% by weight and more preferably 5 to 25% by weight in the stock solution. Moreover, when converted into the amount of the copolymer, it is preferably 0.2 to 12% by weight in the stock solution, more preferably 0.5 to 10% by weight, and 0.75 to 7.5% by weight. % Is more preferable. If the blending amount of the copolymer is less than 0.2% by weight, it is difficult to obtain stretchability in the film, and the curl holding force and setting force are weakened, and the original effect as a styling agent tends to be difficult to obtain. If the amount exceeds 12% by weight, the viscosity of the undiluted solution tends to be high, the handling property tends to be difficult, and further, it tends to be clogged by the aerosol valve or the injection hole of the injection member.

  The polyhydric alcohol adjusts the drying property of the film and adjusts the stretchability of the film to give re-hairing properties, and as an adjusting agent for making the desired setting force while maintaining the curl retention force, It is used for imparting transparency to the film to prevent flaking.

  Furthermore, in the present invention, by using a polyhydric alcohol together with a cationic polymer composition containing vinylpyrrolidone / methacrylamide / vinylimidazole / methylvinylimidazolium methylsulfate copolymer, a flexible, stretchable transparent A film is formed, and the surface of the film is not sticky or sticky, and a dry feel is obtained.

  Examples of the polyhydric alcohol include divalent alcohols such as ethylene glycol, diethylene glycol, propylene glycol, and 1,3-butylene glycol, trivalent alcohols such as glycerin and panthenol, and tetravalent alcohols such as pentaerythritol, Examples include pentavalent alcohols such as glucose, hexavalent alcohols such as sorbitol and mannitol, and these can be used alone or in admixture of two or more. Among these, a divalent or trivalent alcohol is effective in that the effect of adjusting the stretchability of the film is high, high stretchability is obtained, hair can be restyled by hand, and a transparent film is easily obtained. It is preferable to use trivalent alcohol from the viewpoint that the above-mentioned effect is easily obtained, and glycerin and panthenol are more preferable.

  The blending ratio of the polyhydric alcohol is 10 to 500 parts by weight, preferably 20 to 300 parts by weight, and more preferably 30 to 250 parts by weight with respect to 100 parts by weight of the copolymer. . If the blending ratio is less than 10 parts by weight, the effect of adjusting the stretchability of the film tends to be difficult to obtain, and if it exceeds 500 parts by weight, the film becomes more sticky and tends to be sticky.

  The blending amount of the polyhydric alcohol is preferably 0.1 to 30% by weight in the stock solution, and more preferably 0.5 to 20% by weight. When the blending amount of the polyhydric alcohol is less than 0.1% by weight, the stretchability of the film is difficult to be obtained, and the above-mentioned effects tend not to be fully exhibited. Tends to deteriorate and the feeling of use tends to decrease.

  The stock solution used in the present invention is obtained by dissolving, dispersing, or emulsifying a cationic polymer composition, a polyhydric alcohol, and other active ingredients other than the cationic polymer composition in a solvent.

  The solvent can be appropriately selected according to the discharge form of the aerosol composition, and is not particularly limited. Examples thereof include water and lower alcohols, and these may be used alone or in combination of two or more. Can be used.

  Examples of the discharge form include foam type, spray type, spray foam type sprayed in a mist form and foamed on the application surface, gel spray type, etc. The aerosol composition of the present invention is not limited to the entire hair, but also the hair. It is preferable to use it as a foam type because it can be easily applied to a desired portion such as a tip portion of the foam.

  As the water, for example, purified water, ion exchange water, deep ocean water, physiological saline, or the like can be used.

  When the aerosol composition is foamed, the amount of water is preferably 40 to 95% by weight, more preferably 50 to 90% by weight in the stock solution. If the blending amount of water is less than 40% by weight, foaming tends to be difficult, and if it exceeds 95% by weight, the blending amount of the cationic polymer composition, polyhydric alcohol, other active ingredients, etc. decreases, and it is desirable. In order to obtain the effect, the amount used tends to increase.

  When the aerosol composition is made into a spray type, it is not necessary to add water, but it may be added in an amount of 30% by weight or more in the stock solution so as not to ignite the spray particles and to prevent charge accumulation in the hair. Preferably, it is more preferable to mix 40% by weight or more.

  Examples of the lower alcohol include monovalent aliphatic alcohols having 2 to 3 carbon atoms such as ethanol and isopropanol.

  When the aerosol composition is made into a foam type, it is not necessary to add a lower alcohol, but for the purpose of improving the dryness of the applied hair, improving the feeling of use, and adding an active ingredient that does not dissolve in water. It is preferable to mix 40% by weight or less in the stock solution, and more preferably 30% by weight or less. When the lower alcohol exceeds 40% by weight, it tends to be difficult to foam.

  Even if the aerosol composition is made into a spray type, it is not necessary to mix lower alcohol, but the amount of liquefied gas dissolved is increased to mix the amount of liquefied gas suitable for spraying (30% by weight or more in the aerosol composition). It is preferable to add 20 to 95% by weight in the stock solution for the purpose of making it possible to make the spray particles fine and easy to adhere uniformly, to improve the dryness of the applied hair and to improve the feeling of use. 30 to 90% by weight is more preferable.

  Examples of the other active ingredients include nonionic polymers such as polyvinyl pyrrolidone, vinyl acetate / vinyl pyrrolidone copolymer, polyvinyl caprolactam, N-vinyl pyrrolidone / methacrylamide / N-vinyl imidazole copolymer, and vinyl pyrrolidone / N. , N-dimethylaminoethyl methacrylate copolymer diethyl sulfate (polyquaternium 11), methyl vinyl imidazolium chloride / vinyl pyrrolidone copolymer, methyl vinyl imidazolium / vinyl pyrrolidone copolymer methyl sulfate, etc. Styling components such as other cationic polymers of the copolymer; diethylaminohydroxybenzoyl hexyl benzoate, 2-ethylhexyl paramethoxycinnamate, ethylhexyl triazone, oxybenzene, hydroxy UV absorbers such as nzophenone sulfonic acid, sodium dihydroxybenzophenone sulfonate, dihydroxybenzophenone; UV scattering agents such as zinc oxide, titanium oxide, octyltrimethoxysilane-coated titanium oxide; retinol, retinol acetate, retinol palmitate, pantothenic acid Vitamins such as calcium, ascorbic acid, sodium ascorbate, dl-α-tocopherol, tocopherol acetate, tocopherol, tocopherol nicotinate, dibenzoylthiamine, riboflavin and mixtures thereof; pigments such as aluminum powder, silica, iron oxide; yellow 4 No., Yellow No. 5, Yellow No. 202, Yellow No. 203, Red No. 2, Red No. 3, Blue No. 1, Blue No. 2, etc .; Floral, Green, Citrus Green, Green Perfumes such as floral, citrus, rose, rosewood, herbal wood, lemon and peppermint; antiseptics such as paraoxybenzoate and phenoxyethanol.

  The blending amount of the other active ingredient is preferably 0.1 to 20% by weight in the stock solution, and more preferably 0.5 to 10% by weight. When the blending amount of the active ingredient is less than 0.1% by weight, the active ingredient concentration becomes low. Therefore, the amount used tends to increase in order to obtain a desired effect. Tends to be too high and applied over the upper limit of use.

  Furthermore, an oily component can be blended in the stock solution for the purpose of improving the feeling of use, such as giving luster, improving the touch, improving slipperiness and improving the moisture retention.

  Examples of the oil component include diisopropyl adipate, diethoxyethyl succinate, dioctyl succinate, isopropyl myristate, isopropyl palmitate, myristic acid PPG-3 benzyl ether, 2-ethylhexanoic acid cetostearyl, adipic acid di- Ester oil such as 2-ethylhexyl; methylpolysiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, methylcyclopolysiloxane, tetrahydrotetramethylcyclotetrasiloxane, octamethyltrisiloxane, decamethyltetra Silicone oils such as siloxane, methylhydrogenpolysiloxane, methylphenylpolysiloxane; dimethicone crosspolymer, dimethicone Silicone elastomers such as vinyl dimethicone cross polymer, dimethicone / phenyl dimethicone cross polymer, dimethicone / copolyol cross polymer; liquid hydrocarbons such as squalane, squalene, liquid paraffin, isoparaffin; lauric acid, myristic acid, palmitic acid, stearic acid, Fatty acids such as behenic acid, oleic acid, isostearic acid, linoleic acid, linolenic acid; higher alcohols such as lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, aralkyl alcohol, behenyl alcohol, lanolin alcohol; avocado oil, macadamia nut oil, Fats and oils such as shea fat, olive oil and camellia oil; waxes such as beeswax and lanolin wax.

  The blending amount of the oil component is preferably 0.1 to 20% by weight in the stock solution, and more preferably 1 to 10% by weight. When the blending amount of the oil component is less than 0.1% by weight, the effect of the oil component tends to be difficult to obtain. When the blending amount exceeds 20% by weight, the curl holding power and the setting force are reduced. There is a tendency to affect the performance.

  When the aerosol composition for styling of the present invention is a foam type, a surfactant for foaming the stock solution is preferably blended. Even in the case of a spray type, it may be blended for the purpose of imparting flexibility to the hair.

  Examples of the surfactant include sorbitan fatty acid ester, glycerin fatty acid ester, poly (di, tri, tetra, penta, hexa, deca, etc.) glycerin fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene glycerin fatty acid ester, Polyethylene glycol fatty acid ester, polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, polyoxyethylene castor oil / hardened castor oil, polyoxyethylene lanolin alcohol, polyoxyethylene alkylamine, polyoxyethylene fatty acid amide, fatty acid alkyl Roll amide, alkyl polyglucoside, polyoxyethylene / methyl polysiloxane copolymer, polyoxypropylene / methyl polysiloxa Copolymer, poly (oxyethylene / oxypropylene) / methylpolysiloxane copolymer, stearyltrimethylammonium chloride, fatty acid soap, N-acyl glutamate, N-acyl glutamic acid, N-acyl glycine salt, N-acyl alanine salt And a mixture of behentrimonium methosulphate / cetanol / isoalkyl (C10-40) amidopropylethyldimonium methosulphate.

  The blending amount of the surfactant is preferably 0.1 to 20% by weight in the stock solution, and more preferably 0.5 to 10% by weight. If the blending amount of the surfactant is less than 0.1% by weight, the foamability tends to be weak and it is difficult to form a stable foam, and if it exceeds 20% by weight, the sticky feeling becomes strong and the drying property is poor. For example, the feeling of use tends to decrease.

  A stock solution may be prepared by blending the cationic polymer composition, polyhydric alcohol, and other optional components (an active ingredient other than the cationic polymer composition, an oily component, a foaming agent, and the like) in a solvent. it can.

  Furthermore, a pH adjuster may be blended for the purpose of adjusting the pH of the stock solution, saponifying the fatty acid to make a fatty acid soap, and adjusting the foam retention. Examples of the pH adjuster include triethanolamine, diethanolamine, monoethanolamine, diisopropanolamine, 2-amino-2-methyl-1-propanol, 2-amino-2-methyl-1, 3-propanediol, and the like. Organic alkali, potassium hydroxide, sodium hydroxide, ammonium hydroxide, and other inorganic alkalis.

  The blending amount of the pH adjusting agent is preferably an amount for adjusting the pH of the stock solution to 5 to 9, and more preferably an amount for adjusting to 5.5 to 8. If the pH of the stock solution is lower than 5 or higher than 9, the hair and scalp are likely to be adversely affected, and the aerosol container tends to be corroded.

  In addition, a water-soluble polymer may be blended for the purpose of adjusting the viscosity of the stock solution to adjust the hardness of foam and the retention of foam, and for the purpose of increasing the size of spray particles. Examples of the water-soluble polymer include gelatin, agar, casein, dextrin, pectin, starch, carboxymethyl starch, collagen, modified potato starch, sodium alginate, sodium polyacrylate, carrageenan, carboxyvinyl polymer, methylcellulose, ethylcellulose, Examples thereof include hydroxyethyl cellulose, hydroxypropyl cellulose, nitrocellulose, crystalline cellulose, xanthan gum and the like.

  The blending amount of the water-soluble polymer is preferably 0.05 to 5% by weight in the stock solution, and more preferably 0.1 to 3% by weight. When the blending amount of the water-soluble polymer is less than 0.05% by weight, it is difficult to obtain the above effect of blending the water-soluble polymer, and when the blending amount exceeds 5% by weight, the viscosity becomes too high to be handled and the feeling of use. Tends to decrease.

  The blending amount of the stock solution is preferably 60 to 97% by weight, more preferably 65 to 95% by weight in the aerosol composition when the aerosol composition is made into a foam type. If the amount of the stock solution is less than 60% by weight, the foam tends to be coarse and difficult to apply to the hair, and if it exceeds 97% by weight, the foaming property tends to be poor and difficult to apply to the hair.

  In addition, the blending amount of the stock solution is preferably 30 to 70% by weight and more preferably 40 to 65% by weight in the aerosol composition when the aerosol composition is made into a spray type. When the blending amount of the stock solution is less than 30% by weight, the spray particles become too fine, and the spray particles are likely to be scattered and difficult to adhere to the hair. When the amount exceeds 70% by weight, the spray particles become coarse. It tends to stick to the hair and tends to decrease the feeling of use.

  The liquefied gas is a liquid having a vapor pressure inside the container. When the liquefied gas is released into the atmosphere, the liquefied gas is vaporized and acts as a propellant for spraying the undiluted liquid in the form of foam or mist.

  Examples of the liquefied gas include propane, normal butane, isobutane, and liquefied petroleum gas, dimethyl ether, and a mixture of liquefied petroleum gas and dimethyl ether, which are mixtures thereof. The liquefied gas may be mixed with a low boiling point solvent such as normal pentane or isopentane.

  The blending amount of the liquefied gas is preferably 3 to 40% by weight, more preferably 5 to 35% by weight in the aerosol composition when the aerosol composition is made into a foam type. When the blending amount of the liquefied gas is less than 3% by weight, the foamability tends to decrease, and when it exceeds 40% by weight, the foam tends to become rough and difficult to apply to the hair.

  Moreover, when making an aerosol composition into a spray type, it is preferable that it is 30 to 70 weight% in an aerosol composition, and it is more preferable that it is 35 to 60 weight%. If the blended amount of the liquefied gas is less than 30% by weight, the spray particles become rough and tend to stick to the hair and tend to be deteriorated in use, and if it exceeds 70% by weight, the spray particles become too fine, There is a tendency that spray particles are easily scattered and hardly adhere to the hair.

  Furthermore, when the aerosol composition is made into a foam type, the foaming property at low temperature is improved, and when the aerosol composition is made into a spray type for the purpose of imparting gloss to the foam, the spraying force at low temperature is maintained. For this purpose, a compressed gas may be blended. Examples of the compressed gas include nitrogen gas, carbon dioxide gas, nitrous oxide gas, and compressed air.

  Moreover, when mix | blending compressed gas, it is preferable to fill so that the pressure inside an aerosol container may be 0.8 Mpa or less in 35 degreeC, and it is more preferable to fill so that it may become 0.75 Mpa or less. If the pressure inside the aerosol container exceeds 0.8 MPa, the pressure becomes too high at high temperatures, which is not preferable from the viewpoint of safety.

  The aerosol composition of the present invention configured as described above is prepared by preparing a stock solution by blending the cationic polymer composition, a polyhydric alcohol, and optionally an active ingredient into a solvent, and converting the obtained stock solution into a liquefied gas. At the same time, it can be adjusted by filling an aerosol container.

  When the obtained aerosol composition is released from the aerosol container into the atmosphere, the liquefied gas is vaporized, and the stock solution is foamed to form a foam or a nebulized solution. By applying the obtained foam to the hair or attaching a mist, the hair can be styled into a desired shape. In addition, since the aerosol composition of the present invention forms a film having excellent stretchability on the hair, even if the hair is disturbed by wind or the like, it can be easily restored to its original shape by a brush or a hand comb. . Furthermore, since the setting force can be adjusted while maintaining a high curl holding force, it is easy to meet diversifying consumer needs.

<Test method>
(Hair condition)
The obtained aerosol composition (foam) was applied to the hair, styled using a brush and a dryer, and the condition of the hair was evaluated according to the following criteria.
A: Smooth and flexible without flaking.
○: Slight flaking is observed, but smooth and flexible.
Δ: There is no flaking, but it is hard and stiff.
X: There is stickiness.

(Re-hair styling)
The foam was applied to the hair for styling, and after 5 hours, the hair was disturbed by blowing wind, and styling was performed again with a handbrush, and evaluated according to the following criteria.
○: It was possible to return to the shape before disturbance.
X: It did not return to the shape before disturbance.

(Curl retention)
A hair bundle having a length of 15 cm was wound around a curler (diameter 3 cm), and the foam was applied to the hair bundle and dried. A hair bundle was hung in a test room at a temperature of 30 ° C. and a humidity of 90%, and the curl retention after 5 hours was measured.

(Set power)
The foam was applied to a hair bundle having a length of 15 cm and dried. A load was applied to the hair bundle from the lateral direction, and the load (g) required for the hair bundle to bend was measured.

  Examples 1, 2, 4, and 5 are finished smoothly without flaking, have excellent re-hairing properties, and have styling performance with high curl retention and setting power.

  Examples 3, 8, and 9 have a smooth finish without flaking, are excellent in re-styling, and have a high curl holding power, but have a more natural styling performance by suppressing the setting force.

  Example 6 has excellent styling performance similar to Example 1, has styling performance with high curl retention and setting power, and is used with a wax sensation that is applied only to a desired portion of the hair with a fingertip. can do.

  As in Example 1, Example 7 is excellent in re-styling, can further increase curl holding power, and has a more natural styling performance by suppressing the setting force.

  In addition, “−” in Comparative Example 4 indicates that the viscosity was too high to be measured.
