Description

Technical Field

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

Background Art

[0002] As a hair styling agent composition, a clay-like hair styling agent composition is known (for example, Example 13 of Patent Document 1 below). The clay-like hair styling agent composition has a hair styling property of being able to form thin hair bundles and raise the hair. The clay-like hair styling agent composition has a relatively hard property such as a paste-like property and does not have fluidity. Therefore, the clay-like hair styling agent composition is usually filled in a jar container or the like. And at the time of use, the clay-like hair styling agent composition filled in a jar container or the like is taken out from the container with a finger or the like and applied to the hair or the like for hair styling.

[0003] On the other hand, as a hair styling agent excellent in coatability and usability on hair, an aerosol hair styling agent in which a hair styling agent composition and a propellant are filled in an aerosol container is known. Aerosol hair styling agents include various forms such as aerosol spray hair styling agents and aerosol foam hair styling agents. It is essential that the hair styling agent composition for aerosol hair styling agents has fluidity so that it can be discharged well from the aerosol container. Therefore, the conventional clay-like hair styling agent composition cannot be used as the hair styling agent composition for aerosol hair styling agents.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The object of the present invention is to provide an aerosol spray hair styling agent that can form thin hair bundles and enhance the styling power that lifts the hair. [Means for solving the problem]

[0006] The inventors diligently studied aerosol spray hair styling agents that possess the hair styling properties of a clay-like hair styling agent composition, such as being able to form thin hair bundles and enhance the hair-standing power, while also being able to be dispensed in a mist. As a result, the inventors found that the following aerosol spray hair styling agent can solve the above problems.

The present invention provides an aerosol spray hair styling product in which the propellant contains liquefied gas, wherein the total content of component (A) and component (B) in 100% by mass of the hair styling composition is 10.0% by mass or more and 40.0% by mass or less, the content of component (C) in 100% by mass of the hair styling composition is 0.5% by mass or more and 8.0% by mass or less, the content of component (D) in 100% by mass of the hair styling composition is 5.0% by mass or more and 35.0% by mass or less, and the content of component (E) in 100% by mass of the hair styling composition is 30.0% by mass or more and 80.0% by mass or less.

[0008] Ingredient (A): Ingredient A1 below, or Ingredient A1 and Ingredient A2 below Component (A1): Polyoxyethylene alkyl ether with an average number of ethylene oxide additions of 10 or more and 50 or less. Ingredient (A2): Polyoxyethylene hydrogenated castor oil with an average number of ethylene oxide additions of 80 or more and 200 or less. Component (B): Polyoxyethylene hydrogenated castor oil with an average number of ethylene oxide additions of 20 or more and 70 or less. Ingredient (C): Silica Ingredient (D): Water Ingredient (E): Ethanol

[0009] In the aerosol spray hair styling agent of the present invention, it is preferable that the content of the propellant is 30.0% by mass or more and 70.0% by mass or less in the total 100% by mass of the hair styling agent composition and the propellant. [Effects of the Invention]

[0010] The aerosol spray hair styling agent of the present invention can form thin hair strands and enhance the styling power that lifts the hair. [Modes for carrying out the invention]

[0011] The present invention will be described in detail below.

[0012] The aerosol spray hair styling agent of the present invention comprises an aerosol spray 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 inside the aerosol spray container. The hair styling agent composition can be dispensed in a mist from inside the aerosol spray container.

[0013] As described below, the aerosol spray hair styling agent of the present invention comprises a hair styling agent composition containing specific components (A) to (E) in specific amounts, and the propellant contains liquefied gas.

[0014] Because the aerosol spray hair styling agent of the present invention has the above configuration, it can form thin hair bundles and enhance the styling power that lifts the hair.

[0015] The clay-like hair styling composition has the hair styling properties of being able to form thin hair bundles and to lift the hair. The mechanism by which the above hair styling properties of the clay-like hair styling composition are expressed is presumed to be due to the following properties (1) to (4). In other words, it is presumed that the above hair styling properties are expressed by effectively exerting all of the following effects (properties) (1) to (4). However, the mechanism by which the above hair styling properties of the clay-like hair styling composition are expressed is not limited to the above mechanism.

[0016] (1) Slight stickiness: It can stick hairs together to form hair bundles, but it can inhibit the formation of thick hair bundles due to strong stickiness. (2) Hardness: The ability to harden hair to the extent that when thin strands of hair are lifted, the strands do not bend or deform due to their own weight. (3) Toughness: The property of imparting toughness (lack of brittleness) to hair to such an extent that when a thin strand of hair is lifted, the strand does not break (fracture) due to its own weight. (4) Snagging: The characteristic of being able to snag strands of hair on each other.

[0017] The aerosol spray hair styling agent of the present invention, having the above configuration, is presumed to be able to effectively exhibit all of the above effects (1) to (4) despite being an aerosol spray hair styling agent. Furthermore, the effect of (1) above forms thin hair bundles. In addition, when the thin hair bundles are lifted, the effects of (2) and (3) above prevent the hair bundles from breaking or bending due to their own weight, and the effect of (4) above allows the hair bundles to support each other, maintaining an upright state even if they are thin. Therefore, the aerosol spray hair styling agent of the present invention can exhibit the effect of forming thin hair bundles and enhancing the styling power to lift the hair. The aerosol spray hair styling agent of the present invention can exhibit the styling properties of a clay-like hair styling agent composition, which are that it can form thin hair bundles and enhance the styling power to lift the hair, in an aerosol spray hair styling agent. However, the mechanism by which the above styling properties exhibited by the aerosol spray hair styling agent of the present invention are expressed is not limited to the mechanism described above.

[0018] Furthermore, the aerosol spray hair styling agent of the present invention can dispense the hair styling composition in a mist from within the aerosol spray container. The aerosol spray hair styling agent of the present invention allows the hair styling composition to be applied directly to the hair and can be applied evenly, thus offering excellent applicability, ease of use, and convenience. In addition, by using a comb after application, the hair styling composition can be applied without adhering to the palms or other surfaces.

[0019] Furthermore, the aerosol spray hair styling agent of the present invention can improve washability (ease of washing off).

[0020] [Hair styling product composition (aerosol spray hair styling product composition)] The hair styling agent composition in the aerosol spray hair styling agent of the present invention contains "polyoxyethylene alkyl ether with an average addition mole number of ethylene oxide of 10 or more and 50 or less". The above hair styling agent composition does not contain or contains "polyoxyethylene hydrogenated castor oil with an average addition mole number of ethylene oxide of 80 or more and 200 or less". The above hair styling agent composition contains "polyoxyethylene hydrogenated castor oil with an average addition mole number of ethylene oxide of 20 or more and 70 or less", "silica", "water", and "ethanol".

[0021] In this specification, the above "polyoxyethylene alkyl ether with an average addition mole number of ethylene oxide of 10 or more and 50 or less", or the above "polyoxyethylene alkyl ether with an average addition mole number of ethylene oxide of 10 or more and 50 or less" and the above "polyoxyethylene hydrogenated castor oil with an average addition mole number of ethylene oxide of 80 or more and 200 or less" may be referred to as "component (A)".

[0022] In this specification, the above "polyoxyethylene alkyl ether with an average addition mole number of ethylene oxide of 10 or more and 50 or less" may be referred to as "component (A1)".

[0023] In this specification, the above "polyoxyethylene hydrogenated castor oil with an average addition mole number of ethylene oxide of 80 or more and 200 or less" may be referred to as "component (A2)".

[0024] That is, the above hair styling agent composition contains component (A1) or both component (A1) and component (A2) as component (A).

[0025] In this specification, the above "polyoxyethylene hydrogenated castor oil with an average addition mole number of ethylene oxide of 20 or more and 70 or less" may be referred to as "component (B)".

[0026] In this specification, the above "silica" may be referred to as "component (C)".

[0027] In this specification, the above-mentioned "water" may be referred to as "component (D)".

[0028] In this specification, the above-mentioned "ethanol" may be referred to as "component (E)".

[0029] The above hair styling composition contains at least component (A), component (B), component (C), component (D), and component (E). The above hair styling composition may also contain other components other than components (A) to (E). Each of the above components, for example, component (A), component (B), component (C), and other components, may be used individually or in combination of two or more.

[0030] (Component (A)) Component (A) is a polyoxyethylene alkyl ether (Component (A1)) having an average number of added moles of ethylene oxide of 10 or more and 50 or less, or polyoxyethylene hydrogenated castor oil (Component (A2)) having an average number of added moles of ethylene oxide of 80 or more and 200 or less. In other words, Component (A) is either Component (A1), or Component (A1) and Component (A2). Component (A) is a nonionic surfactant. The above hair styling composition may contain only Component (A1) as Component (A), or it may contain both Component (A1) and Component (A2). The above hair styling composition may not contain Component (A2).

[0031] <Ingredients (A1)> Component (A1) is a polyoxyethylene alkyl ether having an average number of ethylene oxide addition moles of 10 or more and 50 or less. Component (A1) is a nonionic surfactant. Component (A1) has weak tackiness and plays a role in moderately suppressing the increase in tackiness caused by components (A2) and (B). Therefore, by using component (A1), the effect of slight tackiness [as described in (1) above] can be effectively exerted. In addition, by using component (A1), the effect of hardness [as described in (2) above] can be effectively exerted. In particular, the effect of (2) above can be exerted more effectively than with component (A2). Component (A1) may be used alone, or two or more may be used in combination.

[0032] From the viewpoint of effectively exhibiting the effects of (1) and (2) described above, the average number of moles of ethylene oxide (EO) added to component (A1) (the average number of moles of EO added to the polyoxyethylene portion) is 10 or more and 50 or less.

[0033] From the viewpoint of making the effects of (1) and (2) described above even more effective, the average number of moles of ethylene oxide (EO) added to component (A1) (the average number of moles of EO added to the polyoxyethylene portion) is preferably 15 or more, and preferably 40 or less.

[0034] From the viewpoint of making the effects of (1) and (2) described above even more effective, component (A1) is preferably a polyoxyethylene alkyl ether (at least one polyoxyethylene alkyl ether) selected from the group consisting of polyoxyethylene cetyl ether, polyoxyethylene stearyl ether, and polyoxyethylene behenyl ether.

[0035] The content of component (A1) is 20.0% by mass or more out of 100% by mass of component (A). If the content of component (A1) is less than 20.0% by mass out of 100% by mass of component (A), the adhesiveness becomes too high, making it difficult to fully exert the effect described in (1) above.

[0036] The content of component (A1) in 100% by mass of component (A) is preferably 40.0% by mass or more, more preferably 50.0% by mass or more, and preferably 95.0% by mass or less. When the content of component (A1) is above the lower limit and below the upper limit, the effects of (1) and (2) described above can be exerted even more effectively. The content of component (A1) in 100% by mass of component (A) may be 100% by mass (total amount).

[0037] <Ingredient (A2)> Component (A2) is polyoxyethylene hydrogenated castor oil having an average number of ethylene oxide additions of 80 or more and 200 or less. Component (A2) is a nonionic surfactant. Component (A2) is an ingredient that can exert the effects of a certain degree of hardness [as described in (2) above] and a certain degree of toughness [as described in (3) above]. Therefore, by using component (A2) in combination with component (A1), the hairstyle and texture (such as the feel of the hardness of the hair bundles) can be adjusted while maintaining the effects of the present invention. Furthermore, by using component (A2) in combination with component (A1), the dispersibility of component (C) in the above hair styling composition can be further enhanced. Component (A2) may be used alone, or two or more may be used in combination.

[0038] From the viewpoint of effectively exhibiting the effects of (2) and (3) described above, the average number of moles of ethylene oxide (EO) added to component (A2) (the average number of moles of EO added to the polyoxyethylene portion) is 80 or more and 200 or less.

[0039] From the viewpoint of making the effects of (2) and (3) described above even more effective, the average number of moles of ethylene oxide (EO) added to component (A2) (the average number of moles of EO added to the polyoxyethylene portion) is preferably 100 or more, and preferably 150 or less.

[0040] <Further details about ingredient (A)> In the above hair styling composition, the content of component (A) is 50.0% by mass or more and 95.0% by mass or less of the total 100% by mass of the combined content of component (A) and component (B). If the content of component (A) is less than 50.0% by mass of the total 100% by mass of the combined content of component (A) and component (B), it is difficult to fully exert the effects of (1) and (2) described above. If the content of component (A) is greater than 95.0% by mass of the total 100% by mass of the combined content of component (A) and component (B), it is difficult to fully exert the effect of (3) described above.

[0041] In the above hair styling composition, the content of component (A) is preferably 55.0% by mass or more, more preferably 60.0% by mass or more, more preferably 90.0% by mass or less, and more preferably 85.0% by mass or less, out of the total 100% by mass of the content of component (A) and the content of component (B). If the content of component (A) is above the lower limit, the effects of (1) and (2) described above can be exhibited more effectively. If the content of component (A) is below the upper limit, the effect of (3) described above can be exhibited more effectively.

[0042] In 100% by mass of the above hair styling composition, the content of component (A) is preferably 5.5% by mass or more, more preferably 6.0% by mass or more, preferably 36.0% by mass or less, and more preferably 30.0% by mass or less. When the content of component (A) is above the lower limit and below the upper limit, the effects of (1) and (2) described above can be exerted even more effectively.

[0043] The content of ingredient (A) refers to the content of ingredient (A1) when the hair styling composition does not contain ingredient (A2), and the total content of ingredient (A1) and ingredient (A2) when the hair styling composition does contain ingredient (A2).

[0044] (Component (B)) Component (B) is polyoxyethylene hydrogenated castor oil having an average number of ethylene oxide additions of 20 or more and 70 or less. Component (B) is a nonionic surfactant. By using component (B2), the toughness effect [as described in (3) above] can be effectively exhibited. In particular, the effect of (3) above can be exhibited more effectively than with component (A2). Component (B) may be used alone, or two or more may be used in combination.

[0045] From the viewpoint of effectively exhibiting the effects of (3) described above, the average number of moles of ethylene oxide (EO) added to component (B) (the average number of moles of EO added to the polyoxyethylene portion) is 20 or more and 70 or less.

[0046] From the viewpoint of making the above-mentioned effect (3) even more effective, the average number of moles of ethylene oxide (EO) added to component (B) (the average number of moles of EO added to the polyoxyethylene portion) is preferably 40 or more, and preferably 60 or less.

[0047] In the above hair styling composition, the total content of component (A) and component (B) is 10.0% by mass or more and 40.0% by mass or less. If the total is less than 10.0% by mass, it is difficult to achieve the effects of the present invention. If the total exceeds 40.0% by mass, the viscosity of the hair styling composition tends to increase, making it difficult to dispense the hair styling composition in a mist from an aerosol spray container.

[0048] In 100% by mass of the above hair styling composition, the total content of component (A) and component (B) is preferably 15.0% by mass or more, more preferably 20.0% by mass or more, and preferably 35.0% by mass or less. When the above total is above the lower limit, the effects of the present invention can be exhibited even more effectively. When the above total is below the upper limit, the hair styling composition can be discharged well in a mist form from the aerosol spray container.

[0049] In 100% by mass of the above hair styling composition, the content of component (B) is preferably 1.0% by mass or more, more preferably 1.5% by mass or more, preferably 18.0% by mass or less, and more preferably 16.0% by mass or less. When the content of component (B) is above the lower limit and below the upper limit, the effect of (3) described above can be exerted even more effectively.

[0050] (Component (C)) Component (C) is silica. By using component (C), the effect described in (4) above can be effectively achieved. By using component (C), hair strands can be caught together and supported by each other, so even thin hair strands can be made to stand up. In addition, by using component (C), the stickiness of the hair after styling can be reduced. Furthermore, by using component (C), a matte (non-glossy) finish can be given to the hair after styling. Component (C) may be used alone, or two or more may be used in combination.

[0051] As component (C), known and conventional silica (anhydrous silicic acid) can be used. The above silica may be anhydrous silicic acid that has not been hydrophobized (hydrophilic silica), or it may be hydrophobized anhydrous silicic acid. Furthermore, the above silica may be silica that has been surface-treated with amino acids, esters, or lecithin, etc. Furthermore, the above silica may be so-called easily disintegrating silica particles.

[0052] Component (C) may be spherical silica or amorphous silica. Amorphous silica is silica that has a shape different from spherical silica. Examples of amorphous silica shapes include those produced by crushing and / or grinding the raw material silica. More specifically, examples of amorphous silica shapes include flake-like, ellipsoidal, cuboidal, polyhedral, and flaky shapes.

[0053] From the viewpoint of making the effect of (4) described above even more effective, it is preferable that component (C) contains amorphous silica.

[0054] In this specification, the above-mentioned "amorphous silica" may be referred to as "component (C1)".

[0055] Therefore, it is preferable that component (C) contains component (C1). The above hair styling composition is preferably composed of component (C1).

[0056] The average particle diameter of component (C) and the average particle diameter of component (C1) are preferably 1.0 μm or more, more preferably 2.0 μm or more, more preferably 50.0 μm or less, and more preferably 20.0 μm or less. When the above average particle diameters are above the lower limit and below the upper limit, the effect of (4) described above can be exerted even more effectively.

[0057] The above average particle diameter is the volume-average particle size. The above average particle diameter can be measured using a particle size distribution analyzer that uses laser diffraction. Examples of such particle size distribution analyzers include the "LA-920" manufactured by Horiba, Ltd.

[0058] Commercially available products can be used as component (C) and component (C1). Examples of commercially available components (C1) include Fuji Silycia Co., Ltd., trade names "Silycia® 250", "Silycia® 320", "Silycia® 370", "Silycia® 470", "Silycia® 530", "Silycia® 550", "Silycia® 710", and "Silycia® 730"; and Evonik Corporation, trade names "CARPLEX® #67" and "CARPLEX® #80". Examples of commercially available components (C) other than component (C1) [i.e., spherical silica] include AGC SI-TEC Co., Ltd., trade name "Sunsphere® H-51"; and JGC Catalysts & Chemicals Co., Ltd., trade name "SILICA PEARL® P-4M".

[0059] In 100% by mass of the above hair styling composition, the content of component (C1) is preferably 0.5% by mass or more, more preferably 1.0% by mass or more, even more preferably 2.0% by mass or more, preferably 8.0% by mass or less, and more preferably 7.0% by mass or less. When the content of component (C1) is above the lower limit and below the upper limit, the effects of (4) described above can be exerted even more effectively.

[0060] The content of component (C) in 100% by mass of the above hair styling composition is 0.5% by mass or more and 8.0% by mass or less. If the content of component (C) is less than 0.5% by mass, it is difficult to fully exert the effect described in (4) above. If the content of component (C) exceeds 8.0% by mass, the viscosity of the above hair styling composition tends to increase, making it difficult to dispense the hair styling composition in a mist from the aerosol spray container.

[0061] In 100% by mass of the above hair styling composition, the content of component (C) is preferably 1.0% by mass or more, more preferably 2.0% by mass or more, and preferably 7.0% by mass or less. If the content of component (C) is above the lower limit, the effect of (4) described above can be exerted even more effectively. If the content of component (C) is below the upper limit, the hair styling composition can be discharged well in a mist form from the aerosol spray container.

[0062] (Component (D)) Ingredient (D) is water. By using ingredient (D), the hair-styling power of ingredients (A) and (B) (especially the effects of (1) to (3) above) can be effectively exerted. Note that if ingredient (D) is not used, it is difficult to enhance the hair-styling power. Ingredient (D) is preferably purified water.

[0063] The content of component (D) in 100% by mass of the above hair styling composition is 5.0% by mass or more and 35.0% by mass or less. If the content of component (D) in 100% by mass of the above hair styling composition is less than 5.0% by mass, it is difficult to fully exert the effects of (1) to (3) described above. If the content of component (D) in 100% by mass of the above hair styling composition exceeds 35.0% by mass, the viscosity of the above hair styling composition tends to increase, making it difficult to properly mix each component and thus difficult to prepare the hair styling composition, or making it difficult to dispense the hair styling composition in a mist from an aerosol spray container.

[0064] In 100% by mass of the above hair styling composition, the content of component (D) is preferably 7.0% by mass or more, more preferably 8.0% by mass or more, preferably 30.0% by mass or less, and more preferably 25.0% by mass or less. If the content of component (D) is above the lower limit, the effects of (1) to (3) described above can be exerted even more effectively. If the content of component (D) is below the upper limit, the hair styling composition can be more easily dispensed in a mist from the aerosol spray container.

[0065] (Component (E)) Component (E) is ethanol. By using component (E), the hair styling composition becomes low viscosity, making it possible to dispense it as an aerosol. In addition, due to the antifoaming effect of component (E), the hair styling composition does not become foamy after dispensing, and can be dispensed as a mist.

[0066] In the above hair styling composition, the content of component (E) is 30.0% by mass or more and 80.0% by mass or less per 100% by mass. Preferably, the content of component (E) is 35.0% by mass or more, preferably 75.0% by mass or less, and more preferably 70.0% by mass or less per 100% by mass of the above hair styling composition. When the content of component (E) is above the lower limit, the hair styling composition can be discharged well in a mist form from the aerosol spray container. When the content of component (E) is below the upper limit, the hair styling power of components (A) and (B) can be exerted even more effectively.

[0067] (Other ingredients) The above hair styling composition may contain other components besides components (A) to (E) described above. These other components are not limited to, but include, for example, oily components, polyhydric alcohols, cooling agents, pH adjusters, preservatives, antioxidants, chelating agents, vitamins, plant and animal extracts, pearlescent agents, colorants, and fragrances. Each of these other components may be used individually or in combination of two or more.

[0068] <Film-forming polymer> From the viewpoint of stably dispensing the hair styling composition in a mist form, it is preferable that the hair styling composition does not contain a film-forming polymer or contains a film-forming polymer in an amount of 0.1% by mass or less. The content of the film-forming polymer in 100% by mass of the hair styling composition is preferably 0.1% by mass or less, more preferably 0.08% by mass or less, even more preferably 0.05% by mass or less, and most preferably 0% by mass (not contained). Therefore, it is most preferable that the hair styling composition does not contain the film-forming polymer. If the content of the film-forming polymer exceeds 0.1% by mass, the film-forming polymer is likely to precipitate in the hair styling composition, which may reduce the dispensing stability. Also, if the film-forming polymer exceeds 0.1% by mass, the ability to restyle hair may decrease.

[0069] Components (A) and (B) are not included in the above-mentioned film-forming polymer. Examples of the above-mentioned film-forming polymer include anionic film-forming polymers, cationic film-forming polymers, amphoteric film-forming polymers, and nonionic film-forming polymers.

[0070] Examples of the above-mentioned anionic film-forming polymers include alkyl (meth)acrylate copolymers, (meth)acrylic acid / alkyl (meth)acrylate copolymers, acrylic resin alkanolamines, 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 maleic acid ester / isoboloryl acrylate copolymers, acrylic acid / alkyl acrylate ester / alkylacrylamide copolymers, polyvinylpyrrolidone / acrylate / (meth)acrylic acid copolymers, (styrene / alkyl acrylate) copolymers, (styrene / acrylamide) copolymers, urethane-acrylic copolymers, and sodium polystyrene sulfonate. Note that "(meth)acrylic" refers to both "acrylic" and "methacrylic".

[0108] (Examples 1-48 and Comparative Examples 1-16) A hair styling product composition (undiluted solution) having the composition shown in Tables 1 to 10 below was prepared by blending the ingredients shown in Tables 1 to 10 below (the blending unit is mass%). The obtained hair styling product composition (undiluted solution) was filled into an aerosol spray container (capacity 95 mL). Next, after clinching the aerosol valve into the aerosol spray container, the propellant shown in Tables 1 to 10 below was filled from the stem, and a suitable button was attached to the stem to produce an aerosol spray hair styling product. The button hole diameter was 0.5 mm, the stem hole diameter was 0.5 mm (number of stem holes: 2), and the housing hole diameter was 1.6 mm for the lower hole and 0.8 mm for the lateral hole. The blending amounts in the tables (amount blended in 100% mass of the hair styling product composition) are shown as the amount blended in pure components (unit: mass%).

[0109] (evaluation) The following evaluations were conducted on the obtained aerosol spray hair styling products. The evaluation results are shown in Tables 1-10. The evaluation was conducted by a panel of three experts, and the evaluation results were determined through deliberation.

[0110] (Test example 1: Discharge properties) The obtained aerosol spray hair styling agent was sprayed uniformly for 6 seconds from a distance of 15 cm onto the entire head of a short-haired wig (lesson mannequin: manufactured by Eucalyptus Japan). The spray pattern and the condition of the sprayed hair were observed, and the discharge performance was evaluated according to the following criteria.

[0111] <Evaluation Criteria for Discharge Performance> 〇〇 (Excellent): The hair styling product composition is dispensed in a fine mist from the aerosol spray container and is transparent on the hair. ○ (Good): The hair styling product is dispensed in a mist from the aerosol spray container, but relatively large droplets are present, resulting in white areas on the hair. × (Defective): The hair styling product composition is not dispensed in a mist from the aerosol spray container (it is dispensed as a foam or a stream of liquid).

[0112] Furthermore, hair styling products that performed poorly in Test Example 1 were not evaluated in subsequent test examples (indicated by "-" in the table).

[0113] (Test example 2: Slight tackiness) In Test Example 1, a wig sprayed with an aerosol hair styling agent was styled by running fingers through the hair from the roots to the ends, working upwards to lift the hair while distributing the styling agent composition evenly throughout the hair. After styling, the hair bundles were touched with the fingertips and their stickiness was evaluated according to the following criteria.

[0114] <Evaluation criteria for slight tackiness> 〇〇 (Optimal): Compared to the state before applying the hair styling product composition, there is a slight feeling of stickiness, but it is almost imperceptible. ○ (Appropriate): Feels slightly sticky. × (Unsuitable): A noticeable stickiness is felt, or no stickiness is felt at all (the feel is the same as before applying the hair styling product).

[0115] (Test example 3: Hardness) In Test Example 2, after styling, a bundle of hair was bent with fingertips, and its stiffness was evaluated according to the following criteria.

[0116] <Hardness Evaluation Criteria> 〇〇 (Optimal): Even with slight pressure applied to the fingertips, resistance can be felt. ○ (Appropriate): It bends slightly when you apply a little pressure to your fingertips. × (Unsuitable): The hair strands bend without resistance.

[0117] (Test example 4: Toughness (resistance to brittleness)) In Test Example 2, after styling, a bundle of hair was bent with the pad of the finger, and its toughness (resistance to brittleness) was evaluated according to the following criteria.

[0118] <Criteria for evaluating toughness (brittleness)> 〇〇 (Optimal): When the hair strands are bent and then released, they recover to almost straight. ○ (Appropriate): Even after bending the hair strands and then releasing them, they only recover to a certain degree of their original bent state. × (Unsuitable): Even after releasing the hair strands after bending them, they remain bent and do not recover.

[0119] (Test example 5: tricky part) In Test Example 2, the resistance felt when running fingers through the hair during styling (the resistance felt as the hair rises as fingers run from bottom to top) was evaluated according to the following criteria to assess snagging.

[0120] <Criteria for evaluating potential snags> 〇〇 (Optimal): Feeling strong resistance ○ (Appropriate): Clearly feels resistance × (Unsuitable): Does not feel resistance

[0121] (Test example 6: Formation of thin hair bundles) In Test Example 2, the wig was visually observed after styling, and the ability to form thin hair bundles was evaluated according to the following criteria.

[0122] <Evaluation criteria for the ability to form thin hair bundles> 〇〇 (Excellent): Almost all strands of hair are independent of each other. ○ (Good): Overall, the hair strands are independent of each other, but there are some areas where the hair strands are clumped together. × (Defective): Almost all the hair strands are stuck together, forming a surface.

[0123] (Test example 7: Hair styling ability to lift hair) In Test Example 2, the angle of the hair standing up near the crown of the wig after styling was observed, and the styling power that allowed the hair to stand up was evaluated according to the following criteria. Note that the above angles are defined as 0° in the horizontal direction and 90° in the vertical direction.

[0124] <Evaluation criteria for hair styling ability to lift hair> 〇〇 (Excellent): Hair stands straight up (at an angle of 75° or more) ○ (Good): Hair stands up (angle is between 45° and 75°) × (Poor): Hair does not stand up well or does not stand up at all (angle is less than 45°)

[0125] The composition and results are shown in Tables 1-10 below. Note that for all comparative examples where the evaluation result for Test Example 2 was "×", the evaluation result was "clearly sticky".

[0126] Furthermore, approximately 100 mL of the hair styling agent composition (undiluted solution) obtained in Examples 12, 28, 29, 30, 31, 36, and 48 was filled into a mayonnaise bottle (capacity 140 mL) and left to stand at 25°C for 24 hours. After standing, the mayonnaise bottle was slowly inverted, and the remaining silica at the bottom of the bottle was observed. As a result, in Examples 28, 29, 30, 31, 36, and 48, no silica remained at the bottom, indicating that the silica was less prone to caking and had excellent silica dispersibility (i.e., excellent production stability). On the other hand, in Example 12, some silica remained at the bottom (however, it was dispersed to the extent that it could be easily stirred).
