Description

[Technical field]

[0001] The present invention relates to an aerosol spray hair styling agent in which a hair styling composition is filled in an aerosol container. [Background technology]

[0002] In recent years, pompadour hairstyles as shown in Figure 1 have become popular in Europe and the US In order to create pompadour hairstyles, it is necessary to fix the hair from the frontal area R1 to the top of the head R2 in a standing position to give a sense of volume, as shown in Figure 1. In addition, in pompadour hairstyles, it is preferable to fix the hair on the top of the head R2 and the sides of the head R3 in a position that does not spread out.

[0003] Conventionally, pompadour hair has been produced using a greasy hair styling composition such as a pomade. The following Patent Document 1 discloses a hair cosmetic that can be used as a pomade. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2020-015700 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, unless the practitioner has a high level of skill, it is difficult to create a pompadour hairstyle using the grease-like hair styling composition. A practitioner with a low level of skill cannot fix the hair in a standing state from the forehead to the top of the head to create a voluminous look, or cannot fix the hair at the sides of the head sufficiently, and therefore cannot create a good pompadour hairstyle.

[0006] In addition, a grease-type hair styling composition requires the user to take the hair styling composition from a container with fingers or the like and apply it to hair to style the hair, which is less convenient. Furthermore, a grease-type hair styling composition may have poor applicability to hair.

[0007] On the other hand, aerosol hair styling agents such as aerosol spray hair styling agents and aerosol foam hair styling agents are known as hair styling agents that have excellent applicability to hair and can be easily used for styling. However, conventional aerosol hair styling agents are not designed to create special hairstyles such as pompadour hair. Therefore, it is difficult to create pompadour hair with conventional aerosol hair styling agents.

[0008] An object of the present invention is to provide an aerosol spray hair styling agent that can easily create pompadour hairstyles. [Means for solving the problem]

[0009] The present invention provides an aerosol container, a hair styling composition, and a propellant, the hair styling composition and the propellant being filled in the aerosol container, the hair styling composition being capable of being discharged in the form of a mist from within the aerosol container, the hair styling composition comprising the following components (A), (B), (C), (D), and (E), the content of component (A) being 0.5% by mass or more and 10.0% by mass or less, the total content of component (B) and component (C) being 9. the total content of the components (D) and (E) is 35.0% by mass or more and 90.5% by mass or less; the mass ratio of the content of the component (C) to the total content of the components (B) and (C) is 0.4 or more; the mass ratio of the content of the component (D) to the total content of the components (D) and (E) is 0.05 or more and 0.45 or less; and the propellant contains the following component (X):

[0012] Ingredient (F): Polyhydric alcohol Effect of the Invention

[0013] The aerosol spray hair styling agent of the present invention makes it easy to create pompadour hairstyles. [Brief description of the drawings]

[0014] [Figure 1] 1(a) and (b) are schematic diagrams showing pompadour hairstyles. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The present invention will be described in detail below.

[0016] The aerosol spray hair styling agent of the present invention comprises an aerosol container, a hair styling agent composition, and a propellant. In the aerosol spray hair styling agent of the present invention, the hair styling agent composition and the propellant are filled in the aerosol container. The hair styling agent composition can be discharged in the form of a mist from the aerosol container.

[0017] In the aerosol spray hair styling agent of the present invention, the hair styling agent composition contains a film-forming polymer, polyoxyethylene hydrogenated castor oil having an average number of moles of ethylene oxide added of 35 or more and 120 or less, polyoxyethylene alkyl ether having an average number of moles of ethylene oxide added of 10 or more and 50 or less and having a cetyl group or a stearyl group, water, and ethanol.

[0018] In the aerosol spray hair styling agent of the present invention, the propellant comprises liquefied petroleum gas.

[0019] In this specification, the above-mentioned "film-forming polymer" may be referred to as "component (A)".

[0020] In this specification, the above-mentioned "polyoxyethylene hydrogenated castor oil having an average number of moles of ethylene oxide added of 35 or more and 120 or less" may be referred to as "component (B)".

[0021] In this specification, the above-mentioned "polyoxyethylene alkyl ether having an average number of moles of ethylene oxide added of 10 or more and 50 or less and having a cetyl group or a stearyl group" may be referred to as "component (C)".

[0022] In this specification, the above-mentioned "water" may be referred to as "component (D)".

[0023] In this specification, the above-mentioned "ethanol" may be referred to as "component (E)."

[0024] In this specification, the above-mentioned "liquefied petroleum gas" may be referred to as "component (X)".

[0025] In the aerosol spray hair styling agent of the present invention, the content of component (A) is 0.5% by mass or more and 10.0% by mass or less, the total content of components (B) and (C) is 9.0% by mass or more and 45.0% by mass or less, and the total content of components (D) and (E) is 35.0% by mass or more and 90.5% by mass or less, based on 100% by mass of the hair styling agent composition.

[0026] In the aerosol spray hair styling agent of the present invention, in the hair styling agent composition, the mass ratio of the content of component (C) to the total content of components (B) and (C) (the content of component (C) / the total content of components (B) and (C)) is 0.4 or more, and the mass ratio of the content of component (D) to the total content of components (D) and (E) (the content of component (D) / the total content of components (D) and (E)) is 0.05 or more and 0.45 or less.

[0027] Since the aerosol spray hair styling agent of the present invention has the above-mentioned configuration, it is possible to easily create pompadour hair. In the present invention, pompadour hair can be easily created compared to the case of using a greasy hair styling agent composition such as pomade, and even a hairdresser or hairstylist with less technical ability can create a good pompadour hair.

[0028] The aerosol spray hair styling agent of the present invention can give appropriate hardness to the hair from the frontal region to the top of the head, and can prevent the hair at the top and sides of the head from spreading out. Furthermore, the aerosol spray hair styling agent of the present invention can apply the hair styling agent composition to the surface of the hair in a mist form, and can prevent the hair styling agent composition from reaching the roots of the hair. Therefore, the aerosol spray hair styling agent of the present invention can fix the hair from the frontal region to the top of the head in a standing state so as to give a sense of volume, and can fix the hair at the top and sides of the head so as not to spread out, and therefore can make a good pompadour hairstyle.

[0029] In addition, when the hair styling composition is applied to hair in the form of an aerosol foam hair styling composition, rather than an aerosol spray hair styling composition, a relatively large amount of the hair styling composition is likely to reach the roots of the hair due to the excellent applicability due to the foam, and the hair is likely to bend at the roots, making it difficult to fix the hair in a standing state with a sense of volume. In addition, in the case of an aerosol foam hair styling composition containing a film-forming polymer, the film formed on the hair is likely to collapse during hair styling, making it even more difficult to fix the hair in a standing state with a sense of volume. For this reason, being an aerosol spray hair styling composition is a technically significant configuration.

[0030] Furthermore, since the aerosol spray hair styling agent of the present invention has the above-mentioned configuration, it is possible to suppress the generation of insoluble matters and further to enhance the ejection stability.

[0031] In the aerosol spray hair styling agent of the present invention, the hair styling agent composition may contain a polyhydric alcohol.

[0032] In this specification, the above-mentioned "polyhydric alcohol" may be referred to as "component (F)".

[0033] The aerosol spray hair styling agent of the present invention contains at least component (A), component (B), component (C), component (D) and component (E) as the hair styling agent composition, and at least component (X) as the propellant. The hair styling agent composition may contain other components in addition to components (A) to (F). The propellant may contain other components in addition to component (X).

[0034] The above components, for example, component (A), component (B), component (C), component (E), component (F) and other components, may each be used alone or in combination of two or more.

[0035] In this specification, the content of each component contained in the hair styling composition means the total content of all the components contained in the hair styling composition. For example, the content of component (A) means the total content of all the components (A) in the hair styling composition.

[0036] [Hair styling composition (aerosol spray hair styling composition)] (Component (A)) Component (A) is a film-forming polymer. By using component (A), it is possible to impart appropriate hardness to hair, so that the hair can be fixed in a standing state so as to have a sense of volume from the frontal region to the top of the head. Only one type of component (A) may be used, or two or more types may be used in combination.

[0037] Examples of component (A) include anionic film-forming polymers, cationic film-forming polymers, amphoteric film-forming polymers, and nonionic film-forming polymers.

[0038] Examples of the anionic film-forming polymer include alkyl (meth)acrylate copolymers, alkyl (meth)acrylate / alkyl (meth)acrylate copolymers, alkanolamine acrylic resins, methyl vinyl ether / maleic acid ester copolymers, vinyl acetate / crotonic acid copolymers, vinyl acetate / crotonic acid / vinyl neodecanoate copolymers, vinyl acetate / crotonic acid / vinyl propionate copolymers, vinyl acetate / monobutyl maleate / isoboryl acrylate copolymers, acrylic acid / alkyl acrylate / alkylacrylamide copolymers, polyvinylpyrrolidone / acrylate / (meth)acrylic acid copolymers, styrene / alkyl acrylate copolymers, styrene / acrylic acid amide copolymers, urethane-acrylic copolymers, and sodium polystyrene sulfonate. Note that "(meth)acrylic" means both "acrylic" and "methacrylic".

[0039] Examples of the cationic film-forming polymer include vinylpyrrolidone·N,N-dimethylaminoethyl methacrylic acid copolymer diethyl sulfate (Polyquaternium-11), vinylpyrrolidone / dimethylaminopropyl methacrylamide / methacryloylaminopropyl lauryl dimethyl ammonium chloride copolymer, dimethyldiallyl ammonium chloride / acrylamide copolymer (Polyquaternium-7), acrylic acid / dimethyldiallyl ammonium chloride copolymer (Polyquaternium-22), (meth)acrylic acid alkyl ester / methacryloyloxyethyl trimethyl ammonium chloride copolymer, butyl methacrylate / methacrylic acid copolymer, Examples include 2-ethoxyethyl acetate / methacryloyloxyethyl trimethyl ammonium chloride copolymer, O-[2-hydroxy-3-(trimethylammonio)propyl]hydroxyethyl cellulose chloride, vinylimidazolium trichloride / vinylpyrrolidone copolymer, hydroxyethyl cellulose / dimethyl diallyl ammonium chloride, polyvinylpyrrolidone / alkylaminoacrylate / vinyl caprolactam copolymer, methylvinylimidazolium chloride-vinylpyrrolidone copolymer, and (vinylpyrrolidone / dimethylaminopropyl methacrylamide / lauryldimethylaminopropyl methacrylamide) copolymer.

[0040] Examples of the amphoteric film-forming polymer include (ethyl betaine methacrylate / acrylates) copolymer, N-methacryloyloxyethyl N,N-dimethylammonium-α-N-methylcarboxybetaine·methacrylic acid alkyl ester copolymer, N,N-dimethyl-N-(2-methacryloyloxyethyl)amine=N-oxide·methacrylic acid alkyl ester copolymer, hydroxypropyl acrylate / butylaminoethyl methacrylate / acrylic acid octylamide copolymer, monochloroacetic acid amphoteric acid amphoteric acid of dialkylaminoethyl methacrylate / methacrylic acid alkyl ester copolymer, and (isobutylene / diethylaminopropylmaleimide / maleic acid) copolymer.

[0041] Examples of the nonionic film-forming polymer include polyvinyl alcohol, polyvinylpyrrolidone, vinyl acetate-vinylpyrrolidone copolymer, vinyl methyl ether-ethyl maleate copolymer, and polyvinyl caprolactam.

[0042] In the above hair styling composition (100% by mass), the content of component (A) is 0.5% by mass or more and 10.0% by mass or less. If the content of component (A) is less than 0.5% by mass, the hair is not sufficiently hardened, and it is difficult to fix the hair in a standing state so as to give a sense of volume from the frontal region to the top of the head. If the content of component (A) exceeds 10.0% by mass, insoluble matter may be generated, and the composition may not be usable as an aerosol spray hair styling agent.

[0043] In the hair styling composition (100% by mass), the content of component (A) is preferably 1.0% by mass or more, and preferably 8.0% by mass or less. When the content of component (A) is equal to or more than the lower limit, the hair can be given firmness more satisfactorily, and the hair can be more satisfactorily fixed in a standing state so as to have a sense of volume from the frontal region to the top of the head. When the content of component (A) is equal to or less than the upper limit, the generation of insoluble matters can be more suppressed, and the ejection stability can be improved.

[0044] (Component (B)) Component (B) is a polyoxyethylene hydrogenated castor oil having an average number of moles of ethylene oxide added of 35 or more and 120 or less. Component (B) is a nonionic surfactant. By using component (B), the adhesive strength between hair strands can be increased while imparting hardness to the hair, so that the hair on the top and sides of the head can be fixed so as not to spread out. Only one type of component (B) may be used, or two or more types may be used in combination.

[0045] In order to increase the adhesive strength between hair strands while imparting hardness to the hair, the average number of moles of ethylene oxide (EO) added in component (B) (average number of moles of EO added in the polyoxyethylene portion) is 35 or more and 120 or less.

[0046] The average number of moles of ethylene oxide added in component (B) is preferably at least 40 and preferably at most 100. When the average number of moles of ethylene oxide added in component (B) is at least the above lower limit and at most the above upper limit, the adhesive strength between hairs can be further increased, and hair on the top and sides of the head can be well fixed so as not to spread out.

[0047] Component (B) preferably contains polyoxyethylene hydrogenated castor oil having an average number of moles of ethylene oxide added of 35 to 65. In this case, the adhesive strength between hair strands can be further increased while still providing the hair with better hardness, so that the hair on the top and sides of the head can be well fixed so as not to spread out.

[0048] In this specification, the above "polyoxyethylene hydrogenated castor oil having an average number of added moles of ethylene oxide of 35 or more and 65 or less" may be referred to as "component (B1)". From the viewpoint of further increasing the adhesive strength between hairs, the average number of added moles of ethylene oxide in component (B1) is preferably 40 or more and preferably 60 or less.

[0049] The mass ratio of the content of component (B1) to the content of component (B) (content of component (B1) / content of component (B)) is preferably 0.4 or more, more preferably 0.5 or more. When the mass ratio (content of component (B1) / content of component (B)) is equal to or more than the lower limit, the adhesive strength between hairs can be further increased.

[0050] In 100% by mass of the hair styling composition, the content of component (B1) is preferably 0.2% by mass or more, more preferably 0.4% by mass or more, and preferably 14.85% by mass or less, more preferably 13.75% by mass or less. When the content of component (B1) is equal to or more than the above lower limit and equal to or less than the above upper limit, the adhesive strength between hairs can be further increased.

[0051] The mass ratio of the content of component (B) to the total content of components (B) and (C) (content of component (B) / total content of components (B) and (C)) is preferably 0.1 or more, more preferably 0.2 or more. When the mass ratio (content of component (B) / total content of components (B) and (C)) is equal to or more than the lower limit, the adhesive strength between hair strands can be further increased while imparting stiffness to the hair, so that the hair on the top and sides of the head can be well fixed so as not to spread out.

[0052] (Component (C)) Component (C) is a polyoxyethylene alkyl ether having an average number of moles of ethylene oxide added of 10 to 50 and having a cetyl group or a stearyl group. Component (C) is a nonionic surfactant. By using component (C), it is possible to impart hardness to hair, so that the hair can be fixed in a raised state so as to have a sense of volume from the frontal region to the top of the head. Only one type of component (C) may be used, or two or more types may be used in combination.

[0053] Component (C) is polyoxyethylene cetyl ether and / or polyoxyethylene stearyl ether, that is, either one or both of polyoxyethylene cetyl ether and polyoxyethylene stearyl ether.

[0054] The average number of moles of ethylene oxide (EO) added in the component (C) (the average number of moles of EO added in the polyoxyethylene portion) is 10 or more and 50 or less.

[0055] The average number of moles of ethylene oxide added in component (C) is preferably at least 15 and preferably at most 45. When the average number of moles of ethylene oxide added in component (C) is at least the above lower limit and is at most the above upper limit, stiffness can be imparted to the hair more satisfactorily, and the hair can be more suitably fixed in a standing state so as to give a sense of volume from the forehead to the top of the head.

[0056] The mass ratio of the content of component (C) to the total content of components (B) and (C) (content of component (C) / total content of components (B) and (C)) is 0.4 or more. If the mass ratio (content of component (C) / total content of components (B) and (C)) is less than 0.4, the hair is not given sufficient stiffness, and it is difficult to fix the hair in a standing state so as to give a sense of volume from the forehead to the top of the head.

[0057] In the hair styling composition 100% by mass, the total content of component (B) and component (C) is 9.0% by mass or more and 45.0% by mass or less. If the total content is less than 9.0% by mass, the hair from the frontal region to the top of the head cannot be fixed in a voluminous state, and the hair at the side of the head cannot be fixed sufficiently, making it difficult to make a pompadour hairstyle. If the total content exceeds 45.0% by mass, insoluble matter may be generated, and the composition may not be usable as an aerosol spray hair styling agent.

[0058] In the hair styling composition (100% by mass), the total content of component (B) and component (C) is preferably 12.0% by mass or more, preferably 40.0% by mass or less. When the total content is equal to or more than the lower limit, the pompadour hair can be made better. When the total content is equal to or less than the upper limit, the generation of insoluble matters can be suppressed, and the ejection stability can be improved.

[0059] (Component (D)) Component (D) is water. Component (D) plays a role as a solvent. In addition, by using component (D), the solubility of component (B) and component (C) can be increased, and further, the above-mentioned effects of component (B) and component (C) can be effectively exhibited. Component (D) is preferably purified water.

[0060] (Component (E)) Component (E) is ethanol. Component (E) functions as a solvent. In addition, by using component (E), the hair styling composition does not become foamy after ejection, and can be ejected in the form of mist.

[0061] From the viewpoint of dissolving each component well and discharging the hair styling composition well in the form of a mist, the total content of component (D) and component (E) is 35.0 mass% or more and 90.5 mass% or less in 100 mass% of the hair styling composition.

[0062] In 100% by mass of the hair styling composition, the total content of component (D) and component (E) is preferably 45.0% by mass or more, more preferably 50.0% by mass or more, and preferably 85.0% by mass or less, more preferably 80.0% by mass or less. When the total content is equal to or more than the lower limit and equal to or less than the upper limit, each component can be well dissolved, and the hair styling composition can be well discharged in a mist form.

[0063] From the viewpoint of satisfactory dissolution of each component and satisfactory ejection of the hair styling composition in the form of a mist, the mass ratio of the content of component (D) to the total content of components (D) and (E) (content of component (D) / total content of components (D) and (E)) is 0.05 or more and 0.45 or less.

[0064] The mass ratio of the content of component (D) to the total content of component (D) and component (E) (content of component (D) / total content of component (D) and component (E)) is preferably 0.1 or more, and preferably 0.4 or less. When the mass ratio (content of component (D) / total content of component (D) and component (E)) is equal to or more than the lower limit, each component can be dissolved more effectively. When the mass ratio (content of component (D) / total content of component (D) and component (E)) is equal to or less than the upper limit, the hair styling composition can be discharged well in the form of a mist.

[0065] (Component (F)) Component (F) is a polyhydric alcohol. The hair styling composition preferably contains component (F). By using component (F), the adhesive strength between hair strands can be further increased, and hair on the top and sides of the head can be well fixed so as not to spread out.

[0066] Examples of the component (F) include glycerin, diglycerin, 1,3-butylene glycol, propylene glycol, dipropylene glycol, 1,2-butanediol, 1,2-pentanediol, 1,2-hexanediol, 1,2-octanediol, 1,2-decanediol, polyethylene glycol, and polyoxypropylene methyl glucoside.

[0067] The content of component (F) in the hair styling composition (100% by mass) is preferably 0.5% by mass or more, more preferably 1.0% by mass or more, and preferably 10.0% by mass or less, and more preferably 9.0% by mass or less.

[0068] (Other ingredients) The hair styling composition may contain other components in addition to the above-mentioned components (A) to (F). The other components are not particularly limited, but examples thereof include surfactants different from both components (B) and (C), oily components (such as vegetable oils), cooling agents, pH adjusters, preservatives, antioxidants, sequestering agents (such as EDTA), vitamins, animal and plant extracts, pearlizing agents, colorants, and fragrances. Only one type of each of the other components may be used, or two or more types may be used in combination.

[0069] The hair styling composition can be produced by a known and commonly used method for producing an aerosol spray hair styling composition. The hair styling composition is not particularly limited, but can be produced, for example, by mixing component (A), component (B), component (C), component (D), component (E), and optionally blended component (F) and other components.

[0070] [Propellant] (Component (X)) Component (X) is liquefied petroleum gas (LPG). By using component (X), the compatibility between the hair styling composition and the propellant can be increased, and the ejection stability can be increased.

Next, after clinching the aerosol valve to the aerosol container, the propellant shown in Table 7 was filled from the stem, and a foam actuator suitable for the stem was attached to prepare an aerosol foam hair styling agent. The blending amounts in the table (blending amounts in 100% by mass of the hair styling composition) are shown as the blending amounts of the pure components (unit: mass%).

[0086] (evaluation) The obtained aerosol spray hair styling agent and aerosol foam hair styling agent were evaluated as follows. The evaluation results are shown in Tables 1 to 7. The evaluation was performed by a panel of three experts, who discussed and decided the evaluation results.

[0087] In addition, in the aerosol spray hair styling agent of Comparative Example 9, the evaluations of Test Examples 1 and 2 were not performed because excessive foaming was observed in the hair styling agent composition.

[0088] (Test Example 1: Occurrence of insoluble matter) The ingredients shown in Tables 1 to 7 below were mixed (unit: mass %) to prepare hair styling compositions (undiluted solutions) having the compositions shown in Tables 1 to 7 below. The obtained hair styling compositions (undiluted solutions) were filled into transparent pressure-resistant bottles (aerosol test bottles, capacity 100 mL). Next, the bottle valve was crimped onto the transparent pressure-resistant bottle, and the propellants shown in Tables 1 to 7 below were filled into the bottles from the stem to prepare evaluation samples.

[0089] The evaluation sample was allowed to stand at −3° C. for 48 hours, and then visually inspected for the presence or absence of insoluble matter. Evaluation was made according to the following criteria.

[0090] <Evaluation criteria for the occurrence of insoluble matter> ○ (Good): No insoluble matter was observed × (bad): Insoluble matter is found

[0091] The aerosol spray hair styling agents of Comparative Examples 3, 6, and 8, which were evaluated poorly in Test Example 1, were not evaluated in the following Test Example 2. On the other hand, the aerosol spray hair styling agents of Comparative Examples 1 and 11, which were evaluated poorly in Test Example 1, were evaluated in the following Test Example 2.

[0092] (Test Example 2: Styling of pompadour hair) A medium-length wig (Lesson Mannequin: manufactured by Eucalyptus Japan Co., Ltd.) was prepared. The front hair of the wig was lifted using a comb, and each aerosol hair styling agent was sprayed evenly onto the front hair for about 5 seconds while flowing from the front to the top of the head.

[0093] Next, each aerosol hair styling agent was sprayed evenly onto the hair at the side of the wig for about 3 seconds while combing the hair toward the back of the head.

[0094] In this way, the pompadour hairstyle was formed, and the hair styling properties of the frontal area, the top of the head, and the sides of the head were checked visually and by touch. The hair styling properties of the pompadour hair were evaluated according to the following criteria.

[0095] <(1) Stylability (hardness) from the forehead to the top of the head> ○○ (Excellent): The hair is firmly fixed from the forehead to the top of the head, standing up to give a sense of volume, and feels firm when touched with the hand. ○ (Good): The hair is fixed in place from the forehead to the top of the head, giving it a sense of volume, but it does not feel stiff. × (Poor): Hair does not stand up to give a sense of volume from the forehead to the top of the head.

[0096] <(2) Hair styling on the top and sides of the head (stickiness)> ○○(Excellent): There is no loose hair on the sides of the head, and the hair on the top and sides of the head is firmly fixed without spreading out. ○ (Good): Although some loose hair was observed on the sides of the head, the hair on the top and sides of the head was fixed and not spread out. × (Poor): Hair is spread out on at least one of the top and sides of the head

[0097] <(3) Evaluation criteria for pompadour hair styling> XX: The evaluation results for "(1) Styling ability from the forehead to the top of the head" and "(2) Styling ability on the top and sides of the head" are both XX, and the hair is excellent for styling pompadour hair. ○: Of the evaluation results of "(1) Styling ability from the forehead to the top of the head" and "(2) Styling ability of the top and sides of the head," one is ○○ and the other is ○, or both are ○, and the styling ability of pompadour hair is good. ×: At least one of the evaluation results of “(1) Styling ability from the forehead to the top of the head” and “(2) Styling ability of the top and sides of the head” is ×, and pompadour hairstyle cannot be created.

[0098] The compositions and results are shown in Tables 1 to 7 below.

[0099] [Table 1]

[0100] [Table 2]

[0101] [Table 3]

[0102] [Table 4]

[0103] [Table 5]

[0104] [Table 6]

[0105] [Table 7]

[0106] In the aerosol spray hair styling agents prepared in Examples 1 to 26, the components (A) to (E) are used in specific amounts, so that the hair from the frontal region to the vertex can be fixed in a raised state to give a sense of volume, and the hair at the vertex and sides can be fixed so as not to spread out, and pompadour hair can be easily and satisfactorily made. In contrast, the aerosol spray hair styling agents prepared in Comparative Examples 1 to 9 produced insoluble matter and did not exhibit the desired hair styling power, making it impossible to make pompadour hair. In addition, in the aerosol foam hair styling agents prepared in Comparative Examples 10 and 11, the hair styling composition spread to the roots of the hair, and it was not possible to fix the hair in a raised state to give a sense of volume. In addition, when Comparative Example 10 and Comparative Example 11 are compared, Comparative Example 10, which uses a hair styling composition containing component (A), was not able to fix the hair in a raised state to give a sense of volume.
