Description

Technical Field

[0001] The present invention relates to an aerosol spray hair cosmetic in which an aerosol container is filled with a hair cosmetic composition. Background Art

[0002] Aerosol hair dressings are commercially available in which a hair dressing composition is filled in an aerosol container. In the hair dressing composition used for the aerosol hair dressing, a film-forming polymer is usually mixed as a hair dressing component. In addition, by using the hair dressing composition mixed with the film-forming polymer, a film is formed on the hair, the reflection of light is enhanced, and gloss can be given to the hair.

[0003] On the other hand, in recent years, hairstyles with natural styling in which the gloss is suppressed have become increasingly popular.

[0004] Patent Document 1 below discloses a non-foaming hair spray composition comprising a hair styling stock solution and a propellant, wherein the hair styling stock solution contains 1 to 70% by mass of (A) methylal and 0.1 to 20% by mass of (B) a film-forming resin in 100% by mass of the hair styling stock solution, and the ratio (mass ratio) of the hair styling stock solution to the propellant is 80:20 to 20:80.

[0005] Patent Document 2 below discloses a hair styling cosmetic comprising (A) methylphenyl polysiloxane and (B) dipentaerythritol fatty acid ester. The hair styling cosmetic can be used as an aerosol hair spray composition.

[0006] Patent Document 3 below discloses a hair styling material comprising a clay mineral (A), an (acrylic acid / behenyl alcohol polyether methacrylate) copolymer (B), waxes (C), liquid oil (D), a film-forming resin (E), a nonionic surfactant (F) that is liquid at 25° C., and a polyoxyethylene alkyl ether (G) in specific blending amounts. In the specification of Patent Document 3, the properties of the hair styling material are described as milky, creamy, gely, emulsiony, waxy, and foamy.

[0011] Patent Document 3: Japanese Patent Application Publication No. 2019-194167 Summary of the invention

[0012] Problems to be solved by the invention

[0013] The hair sprays described in Patent Documents 1 and 2 can give natural gloss to the hair after styling and can suppress gloss compared to conventional hair sprays. However, even the hair sprays described in Patent Documents 1 and 2 do not have sufficient gloss suppression effect and it is difficult to give a matte texture to the hair.

[0014] The hair styling material described in Patent Document 3 can suppress gloss to a certain extent by the clay minerals mixed therein. However, even the hair styling material described in Patent Document 3 does not have a sufficient gloss suppression effect, and it is difficult to give a matte texture to the hair. In addition, in the case of a hair styling material mixed with a clay mineral, the feel of the hair after styling becomes worse. In addition, when a hair styling material mixed with a clay mineral is used as a composition for aerosol spray, clogging may occur, and the composition cannot be discharged well from the aerosol container.

[0015] In addition, in the case of conventional aerosol spray hair cosmetics, precipitates may be generated immediately after the aerosol spray hair cosmetics are prepared. If precipitates are generated, clogging may occur or the formulation stability may be reduced.

[0016] An object of the present invention is to provide an aerosol spray hair cosmetic which can impart a matte texture with significantly suppressed gloss to hair and can suppress the generation of precipitates in the aerosol spray hair cosmetic immediately after production.

[0017] Means for solving problems

[0018] The present invention provides an aerosol spray hair cosmetic comprising an aerosol spray container, a hair cosmetic composition and a propellant, wherein the aerosol spray container is filled with the hair cosmetic composition and the propellant, the hair cosmetic composition comprising the following component (A), the following component (B) and the following component (C), wherein the total content of the component (A) and the component (B) in 100% by mass of the hair cosmetic composition is 1.5% by mass or more and 12.0% by mass or less, and in the hair cosmetic composition, the mass ratio of the content of the component (B) to the content of the component (A) is 0.30 or more and 6.50 or less, and the propellant comprises the following component (X).

[0019] Component (A): anionic film-forming polymer and / or amphoteric film-forming polymer

[0020] Component (B): Silicone modified acrylic resin

[0021] Ingredient (C): Ethanol

[0022] Ingredient (X): Dimethyl ether

[0024] Effects of the Invention

[0025] The aerosol spray hair cosmetic of the present invention can provide a matte texture with significantly suppressed gloss to hair, and can suppress the generation of precipitates in the aerosol spray hair cosmetic immediately after preparation. DETAILED DESCRIPTION

[0026] The present invention is described in detail below.

[0027] The aerosol spray hair cosmetic of the present invention comprises an aerosol spray container, a hair cosmetic composition and a propellant. The aerosol spray hair cosmetic of the present invention is filled with the hair cosmetic composition and the propellant in the aerosol spray container. The aerosol spray hair cosmetic of the present invention can discharge the hair cosmetic composition in the form of mist from the aerosol spray container.

[0028] In the aerosol spray hair cosmetic of the present invention, the hair cosmetic composition comprises an anionic film-forming polymer and / or an amphoteric film-forming polymer, a silicone-modified acrylic resin and ethanol.

[0029] In this specification, the above-mentioned "anionic film-forming polymer and / or amphoteric film-forming polymer" may be referred to as "component (A)".

[0030] In this specification, the above-mentioned "silicone-modified acrylic resin" may be referred to as "component (B)".

[0031] In this specification, the above-mentioned "ethanol" may be referred to as "component (C)".

[0032] In the aerosol spray hair cosmetic of the present invention, the total content of component (A) and component (B) in 100% by mass of the hair cosmetic composition is 1.5% by mass or more and 12.0% by mass or less, and in the hair cosmetic composition, the mass ratio of the content of component (B) to the content of component (A) is 0.30 or more and 6.50 or less.

[0033] In the aerosol spray hair cosmetic of the present invention, the propellant contains dimethyl ether.

[0034] In this specification, the above-mentioned "dimethyl ether" may be referred to as "component (X)".

[0035] As described above, the aerosol spray hair cosmetic of the present invention comprises at least component (A), component (B) and component (C) as the hair cosmetic composition, and comprises at least component (X) as the propellant. The hair cosmetic composition may comprise other components in addition to components (A) to (C). The propellant may comprise other components in addition to component (X).

[0036] The above-mentioned components, for example, the component (A), the component (B), the component (C), and other components may be used alone or in combination of two or more.

[0037] The aerosol spray hair cosmetic of the present invention can provide a matte texture with significantly suppressed gloss to hair, and can suppress the generation of precipitates in the aerosol spray hair cosmetic immediately after preparation.

[0038] In the aerosol spray hair cosmetic of the present invention, the component (A) and the component (B) having different solubility in the component (X) are used in specific blending amounts. Therefore, after the hair cosmetic composition is applied to the hair, when the solvent such as the component (B) evaporates, an uneven surface is formed on the hair.

[0039] Therefore, a matte texture with little or no gloss can be imparted to the hair.

[0040] In addition, the aerosol spray hair cosmetic of the present invention can improve the compatibility between the hair cosmetic composition and the propellant, and thus can suppress the generation of precipitates in the aerosol spray hair cosmetic immediately after preparation, thereby improving the formulation stability, and making it less likely to cause clogging, thereby improving the discharge stability.

[0041] [Hair cosmetic composition (aerosol spray hair cosmetic composition)]

[0042] (ingredient (A))

[0043] Component (A) is an anionic film-forming polymer and / or an amphoteric film-forming polymer.

[0044] Component (A) may be an anionic film-forming polymer, an amphoteric film-forming polymer, or both an anionic film-forming polymer and an amphoteric film-forming polymer. Component (A) functions as a hair styling component. By using component (A), the hair styling power can be improved. Component (A) may be used alone or in combination of two or more.

[0045] As the above-mentioned anionic film-forming polymer, there can be mentioned (meth) alkyl acrylate copolymers, (meth) acrylic acid / (meth) alkyl acrylate copolymers, (acrylic acid (esters) / alkyl (C1-18) acrylate / alkyl (C1-8) acrylamide) copolymers AMP, (alkyl acrylate / diacetone acrylamide) copolymers AMP, methyl vinyl ether / maleate copolymers, vinyl acetate / crotonic acid copolymers, vinyl acetate / crotonic acid / vinyl neodecanoate copolymers, vinyl acetate / crotonic acid / vinyl propionate copolymers, vinyl acetate / monobutyl maleate / isobornyl acrylate copolymers, polyvinyl pyrrolidone / acrylate / (meth) acrylic acid copolymers, (styrene / alkyl acrylate) copolymers, (styrene / acrylamide) copolymers, carbamate-acrylic acid copolymers, and sodium polystyrene sulfonate. It should be noted that "(meth) acrylic acid" refers to both "acrylic acid" and "methacrylic acid".

[0046] Examples of the above-mentioned amphoteric film-forming polymers include (ethyl betaine methacrylate / acrylic acid (ester)) copolymers, N-methacryloyloxyethyl N,N-dimethylammonium-α-N-methylcarboxy betaine·alkyl methacrylate copolymers, N,N-dimethyl-N-(2-methacryloyloxyethyl)amine=N-oxide·alkyl methacrylate copolymers, hydroxypropyl acrylate / butylaminoethyl methacrylate / octyl acrylate amide copolymers, monochloroacetic acid amphoterics of dialkylaminoethyl methacrylate / alkyl methacrylate copolymers, and (isobutylene / diethylaminopropylmaleimide / maleic acid) copolymers.

[0047] In 100% by mass of the hair cosmetic composition, the content of the component (A) is preferably 0.5% by mass or more, more preferably 2.0% by mass or more, preferably 7.0% by mass or less, and more preferably 5.0% by mass or less. When the content of the component (A) is at least the above lower limit and at most the above upper limit, a matte texture can be further imparted to the hair. When the content of the component (A) is at least the above lower limit, the hair styling property can be further improved. When the content of the component (A) is at most the above upper limit, the compatibility of the hair cosmetic composition with the propellant can be further improved, and the generation of precipitates can be effectively suppressed in the aerosol spray hair cosmetic immediately after preparation.

[0048] (Component (B))

[0049] Component (B) is a silicone-modified acrylic resin. Component (B) functions as a hair styling component. By using component (A) and component (B) together, a matte texture with significantly suppressed gloss can be given to the hair. Component (B) can be used alone or in combination of two or more.

[0050] Component (B) includes (acrylic acid / polytrimethylsiloxane methacrylate) copolymer, (alkyl acrylate / bisacetoneamide / amino-terminated polydimethylsiloxane) copolymer AMP, (alkyl acrylate / polydimethylsiloxane) copolymer, and (acrylic acid / stearyl alcohol acrylate / polydimethylsiloxane methacrylate) copolymer.

[0051] From the viewpoint of imparting a matte texture with considerably suppressed gloss to hair, in the hair cosmetic composition, the mass ratio of the content of the component (B) to the content of the component (A) (content of the component (B) / content of the component (A)) is from 0.30 to 6.50.

[0052] In the hair cosmetic composition, the mass ratio of the content of the component (B) to the content of the component (A) (content of the component (B) / content of the component (A)) is preferably 0.40 or more, more preferably 0.80 or more, and preferably 6.00 or less, more preferably 5.50 or less. When the mass ratio (content of the component (B) / content of the component (A)) is not less than the above lower limit and not more than the above upper limit, a matte texture can be further imparted to the hair.

[0053] In 100% by mass of the hair cosmetic composition, the content of the component (B) is preferably 1.0% by mass or more, more preferably 3.0% by mass or more, preferably 9.0% by mass or less, more preferably 6.0% by mass or less. When the content of the component (B) is at least the above lower limit, a matte texture can be further imparted to the hair, and the hair styling ability can be further improved. When the content of the component (B) is at most the above upper limit, the compatibility of the hair cosmetic composition with the propellant can be further improved, and the formulation stability can be further improved. In addition, whitening of the hair can be effectively suppressed.

[0054] In 100% by mass of the hair cosmetic composition, the total content of component (A) and component (B) is 1.5% by mass or more and 12.0% by mass or less. If the total content is less than 1.5% by mass, gloss is easily generated, and it is difficult to give a matte texture to the hair. If the total content exceeds 12.0% by mass, whitening is easily generated on the hair, and it is difficult to give a matte texture to the hair. In addition, the compatibility of the hair cosmetic composition with the propellant is reduced, and the formulation stability is likely to be reduced.

[0055] In 100% by mass of the hair cosmetic composition, the total content of component (A) and component (B) is preferably 3.0% by mass or more, more preferably 5.0% by mass or more, preferably 11.5% by mass or less, more preferably 10.5% by mass or less. When the total content is at least the lower limit, a matte texture can be further imparted to the hair, and the hair styling property can be further improved. When the total content is at most the upper limit, the compatibility of the hair cosmetic composition with the propellant can be further improved, and the formulation stability can be further improved. In addition, whitening of the hair can be effectively suppressed.

[0056] (ingredient (C))

[0057] Component (C) is ethanol. Component (C) functions as a solvent. In addition, by using component (C), a non-aqueous hair cosmetic composition or a hair cosmetic composition with a low water content can be prepared, thereby further improving hair styling properties and quick-drying properties.

[0058] In 100% by mass of the hair cosmetic composition, the content of the component (C) is preferably 65.0% by mass or more, more preferably 70.0% by mass or more, preferably 90.0% by mass or less, more preferably 85.0% by mass or less. When the content of the component (C) is at least the above lower limit and at most the above upper limit, the hair styling property and quick-drying property can be further improved.

[0122] The ingredients shown in Tables 1 to 7 below were mixed (the mixing unit is mass %) to prepare hair cosmetic compositions (stock solutions) having the compositions shown in Tables 1 to 7 below. The obtained hair cosmetic compositions (stock solutions) were filled into an aerosol spray container (transparent pressure-resistant bottle, capacity 95 mL). Next, after the aerosol spray container was closed with an aerosol valve, the propellant shown in Tables 1 to 7 below was filled using the valve stem, and a button suitable for the valve stem was attached to prepare an aerosol spray hair cosmetic. The mixing amounts in the tables (mixing amounts in 100 mass % of the hair cosmetic composition and mixing amounts in 100 mass % of the propellant) are expressed as the mixing amounts of pure components (unit: mass %). In the tables, isododecane, polydimethylsiloxane and water are contained from the above-mentioned commercial products containing component (A) or component (B).

[0123] (evaluate)

[0124] The obtained aerosol spray hair cosmetics were evaluated as follows. The evaluation results are shown in Tables 1 to 7. The evaluation was performed by 5 expert panelists, and the evaluation results were determined through consultation.

[0125] (Test Example 1: Matte Feel)

[0126] A wig with short hair (trade name "A-386": manufactured by YUKARI JAPAN) is prepared. In addition, a gel-like hair dressing composition (trade name "Mandom Long keep gel wet & hard") is prepared. 1.0 g of the gel-like hair dressing composition is applied to the hair of the left and right halves of the wig and dried. Next, the obtained aerosol spray hair cosmetic is evenly sprayed on the hair of the right half of the wig from a distance of 15 to 20 cm for 3 seconds. The hair of the wig is visually observed, and the matte feeling is evaluated according to the following criteria based on the gloss of the left half. It should be noted that the gloss can be clearly confirmed in the hair of the left half to which only the gel-like hair dressing composition is applied. When the judgment result is "A" or "B", hair with a matte texture in which the gloss is considerably suppressed is obtained.

[0127] <Evaluation criteria for matte finish>

[0128] A: Compared with the standard, there is no gloss at all, and the matte feeling is quite excellent.

[0129] B: Almost no gloss compared to the standard, excellent matte feel.

[0130] C: Compared with the standard, the gloss can be reduced, but the matte feeling is poor.

[0131] D1: Glossiness equal to that of the standard can be clearly confirmed.

[0132] D2: Whitening occurs.

[0133] (Test Example 2: Properties of Aerosol Spray Hair Cosmetics Immediately After Preparation)

[0134] The aerosol spray hair cosmetics immediately after production were visually observed inside the aerosol spray container and evaluated based on the following criteria.

[0135] <Evaluation Criteria for Properties of Aerosol Spray Hair Cosmetics Immediately After Production>

[0136] A: No precipitate was generated, and the product was colorless and transparent.

[0137] B: Although no precipitate was generated, the sample was slightly turbid.

[0138] C: Precipitate was generated and the product was slightly turbid.

[0139] D: Precipitate is generated and the product is white and turbid.

[0140] The compositions and results are shown in Tables 1 to 7 below.
