Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, sometimes hair is permed using specialized equipment. Perming the hair makes it possible to create hairstyles that would be difficult to achieve without perming, and these hairstyles can be maintained for several weeks to several months. However, perming has the drawback that if the permed hairstyle doesn't suit you or you don't like it, it's difficult to return the hair to its original state. Also, perming can damage the hair and scalp.

[0006] For example, if it were possible to create a perm-like hairstyle using hair styling products, the aforementioned drawbacks would be overcome, and one could enjoy the desired perm-like hairstyle only while styling. However, creating perm-like hairstyles using hair styling products has not been sufficiently investigated. It is also not yet fully understood what kind of hair styling product with specific styling properties is suitable for creating perm-like hairstyles.

[0007] As a result of diligent research, the inventors have discovered that it is possible to create a perm-like hairstyle by imparting strong curls to the hair and lifting it up.

[0008] Therefore, the object of the present invention is to provide a hair styling agent that can enhance the styling power to strongly curl hair and the styling power to make hair stand up. [Means for solving the problem]

[0009] The present invention provides an aerosol foam hair styling agent comprising an aerosol container, a hair styling agent composition, and a propellant, wherein the aerosol container is filled with the hair styling agent composition and the propellant, the hair styling agent composition can be dispensed in a foam form from the aerosol container, the hair styling agent composition contains the following components (A), (B), (C), and (D), the content of component (A) is 0.5% by mass or more, the content of component (B) is 0.5% by mass or more, the total content of component (A) and component (B) is 8.0% by mass or more and 25.0% by mass or less, and the propellant contains liquefied gas.

[0010] Ingredient (A): Carnauba wax Ingredient (B): Beeswax Ingredients (C): Nonionic surfactant Ingredient (D): Water

[0011] In the aerosol foam hair styling agent of the present invention, it is preferable that the hair styling agent composition contains the following component (E).

[0012] Component (E): A liquid oil at 25°C selected from the group consisting of hydrocarbon oils and ester oils.

[0013] In the aerosol foam hair styling agent of the present invention, it is preferable that component (C) contains the following component (C1).

[0014] Ingredient (C1): Polyoxyethylene alkyl ether

[0015] In the aerosol foam hair styling agent of the present invention, it is preferable that component (C) contains the following component (C2).

[0016] Ingredient (C2): Polyoxyethylene glycerin fatty acid ester

[0017] In the aerosol foam hair styling agent of the present invention, it is preferable that the hair styling agent composition does not contain an oil agent that is solid at 25°C and is different from both the component (A) and the component (B), or contains it at 1.0% by mass or less.

Advantages of the Invention

[0024] In this specification, the above-mentioned "beeswax" may be referred to as "component (B)".

[0025] In this specification, the above-mentioned "nonionic surfactant" may be referred to as "component (C)".

[0026] In this specification, the above-mentioned "water" may be referred to as "component (D)".

[0027] Therefore, in the aerosol foam hair styling agent of the present invention, the hair styling agent composition comprises component (A), component (B), component (C), and component (D).

[0028] In the aerosol foam hair styling agent of the present invention, the content of component (A) is 0.5% by mass or more, the content of component (B) is 0.5% by mass or more, and the total content of component (A) and component (B) is 8.0% by mass or more and 25.0% by mass or less, in 100% by mass of the above hair styling agent composition.

[0029] In the aerosol foam hair styling agent of the present invention, the propellant includes a liquefied gas.

[0030] The aerosol foam hair styling agent of the present invention has the above-described configuration, which enhances the hair styling power to create strong curls and to lift the hair.

[0031] Therefore, the aerosol foam hair styling agent of the present invention can be used to style hair into a perm-like hairstyle. However, the hairstyles that can be styled with the aerosol foam hair styling agent of the present invention are not limited to perm-like hairstyles.

[0032] In the aerosol foam hair styling agent of the present invention, since the hair styling agent composition contains components (A) and (B), it can fix the hairs in an adhesive state, and exhibits a hair styling power that curls the hair. Furthermore, in the aerosol foam hair styling agent of the present invention, some of components (A) and (B) contained in the hair styling agent composition precipitate on the hair, forming fine crystals. It is presumed that these fine crystals cause the hairs to catch on each other, resulting in a hair styling power that lifts the hair. In addition, in the aerosol foam hair styling agent of the present invention, when the hair styling agent composition is applied to the hair, the excellent applicability due to its foamy (foamy) state allows the hair styling agent composition to easily reach the roots of the hair. Therefore, the hair styling agent composition can be applied uniformly to the entire hair with a relatively thin application thickness, and the hair styling power that curls the hair as described above is strongly exhibited, making it possible to curl the hair strongly. Furthermore, a strong hair styling power that lifts the hair as a whole is exhibited, making it possible to create a voluminous, three-dimensional hairstyle. Therefore, the aerosol foam hair styling agent of the present invention can be used to style hair into a perm-like hairstyle.

[0033] Furthermore, when styling hair using a conventional wax-type hair styling product instead of an aerosol foam hair styling product, it is difficult to apply the hair styling product evenly to the entire hair. Therefore, even if the wax-type hair styling product contains ingredients (A) and (B), it is not possible to style hair into a perm-like hairstyle. Also, when applying the hair styling product to the hair in the form of an aerosol spray hair styling product instead of an aerosol foam hair styling product, the hair styling product does not easily reach the roots of the hair, and the drying time of the hair styling product is extremely short, making it impossible to style the entire hair. For this reason, even when applying the hair styling product to the hair in the form of an aerosol spray hair styling product, it is not possible to style hair into a perm-like hairstyle.

[0034] Therefore, the fact that it is an aerosol foam hair styling agent, and that the hair styling agent composition contains components (A) and (B), is a configuration of particular technical significance.

[0035] In the aerosol foam hair styling agent of the present invention, the hair styling agent composition may contain an oil that is liquid at 25°C, selected from the group consisting of hydrocarbon oils and ester oils.

[0036] In this specification, the above-mentioned "liquid oil at 25°C selected from the group consisting of hydrocarbon oils and ester oils" may be referred to as "component (E)".

[0037] The aerosol foam hair styling agent of the present invention comprises, as the hair styling agent composition, at least component (A), component (B), component (C), and component (D), and comprises at least liquefied gas as the propellant. The hair styling agent composition may also contain other components besides components (A) to (D).

[0038] Each of the above components, such as component (A), component (B), component (C), component (E), and other components, may be used individually or in combination of two or more types.

[0039] In this specification, the content of each component in the hair styling composition means the total content of all components contained in the hair styling composition. For example, the content of component (C) means the total content of all components (C) in the hair styling composition.

[0040] [Hair styling product composition (aerosol foam hair styling product composition)] (Component (A)) Component (A) is carnauba wax. It is presumed that using component (A) causes fine crystals of component (A) to precipitate on the hair, making the hairs more likely to catch on each other and increasing the styling power to make the hair stand up. Furthermore, it is presumed that the coating on the hair makes it harder, thus increasing the styling power to make the hair curl. Component (A) may be used alone, or two or more may be used in combination.

[0041] Component (A) is a compound whose INCI name (International Nomenclature of Cosmetic Ingredients) is Copernicia Cerifera (Carnauba) Wax.

[0042] Examples of commercially available products containing ingredient (A) include the product names "TOWAX-1F8" (manufactured by Toa Kasei Co., Ltd.), "Carnauba Wax No. 1" (manufactured by Kato Yoko Co., Ltd.), and "Carnauba Wax Refined No. 1" (manufactured by Cerarica NODA Co., Ltd.).

[0043] From the viewpoint of enhancing the hair-curling and hair-lifting capabilities, and especially from the viewpoint of enhancing the hair-lifting capabilities, the content of component (A) in 100% by mass of the above hair-styling composition is 0.5% by mass or more.

[0044] In 100% by mass of the above hair styling composition, the content of component (A) is preferably 1.5% by mass or more, more preferably 2.5% by mass or more, even more preferably 5.0% by mass or more, particularly preferably 7.0% by mass or more, preferably 20.0% by mass or less, and more preferably 15.0% by mass or less. If the content of component (A) is above the lower limit, the hair styling power that lifts the hair can be further enhanced. If the content of component (A) is below the upper limit, the formulation stability (emulsification stability) can be enhanced.

[0045] (Component (B)) Component (B) is beeswax. By using component (B), the hairs can be effectively fixed in place by their adhesive properties, thereby enhancing the styling power, especially for curling the hair. Furthermore, it is presumed that the coating on the hair makes it stiffer, thus also enhancing the styling power for lifting the hair. Component (B) may be used alone, or two or more types may be used in combination.

[0046] Component (B) is, for example, a wax obtained from the residue left after honey has been extracted from a beehive by methods such as heated pressing and solvent extraction. The above-mentioned "beeswax" includes "bleached beeswax," which is beeswax that has been bleached by methods such as sun bleaching, chemical bleaching, and adsorption.

[0047] From the viewpoint of enhancing the hair-curling and hair-standing capabilities, and particularly from the viewpoint of enhancing the hair-curling capabilities, the content of component (B) in 100% by mass of the above hair-styling composition is 0.5% by mass or more.

[0048] 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 3.0% by mass or more, preferably 15.0% by mass or less, more preferably 12.0% by mass or less, and even more preferably 10.0% by mass or less. If the content of component (B) is above the lower limit, the hair styling power that curls the hair can be further enhanced. If the content of component (B) is below the upper limit, the formulation stability (emulsification stability) can be enhanced.

[0049] In the present invention, both component (A) and component (B) exert the effect of hardening the hair after coating by coating the hair. By imparting grip to this hair which has a certain degree of hardness, excellent hair styling power that lifts the hair is obtained, and furthermore, by imparting adhesiveness, excellent hair styling power that curls the hair is obtained. From the viewpoint of exerting the effects of the present invention by hardening the hair after coating as described above, the total content of component (A) and component (B) in 100% by mass of the hair styling composition is 8.0% by mass or more. Also, from the viewpoint of improving formulation stability (emulsification stability), the total content of component (A) and component (B) in 100% by mass of the hair styling composition is 25.0% by mass or less.

[0050] In 100% by mass of the above hair styling composition, the total content of component (A) and component (B) is preferably 10.0% by mass or more, more preferably 12.0% by mass or more, preferably 23.0% by mass or less, and more preferably 22.5% by mass or less. When the above total content is above the lower limit and below the upper limit, the effects of the present invention can be exhibited more effectively. When the above total content is below the upper limit, the emulsification stability can be further enhanced.

The obtained hair styling composition (concentrate) was filled into an aerosol container (φ35mm × 105mm, aluminum can, container capacity 91mL). Next, after clinching the aerosol valve into the aerosol container, the propellant shown in Tables 1-5 was filled from the stem, and a foam actuator suitable for the stem was attached to produce an aerosol foam hair styling agent. The blending amounts in the tables (amounts blended in 100% mass of the hair styling composition) are shown as pure blending amounts (unit: mass%).

[0112] (Comparative Example 9) Making an aerosol spray hair styling product: A hair styling product composition (concentrate) having the composition shown in Table 5 below was prepared by blending the ingredients shown in Table 5 below (the blending unit is mass%). The obtained hair styling product composition (concentrate) was filled into an aerosol spray container (φ35mm × 105mm, aluminum can, container capacity 91mL). Next, the aerosol valve was clinched into the aerosol spray container, the propellant shown in Table 5 below was filled from the stem, and a suitable spray button was attached to the stem to produce an aerosol spray hair styling product. The blending amounts in the table (amounts blended in 100% mass of the hair styling product composition) are shown as the amount of pure components (unit: mass%).

[0113] (evaluation) The following evaluations were conducted on the obtained aerosol foam hair styling products and aerosol spray hair styling products. The evaluation results are shown in Tables 1 to 5. The evaluation was conducted by a panel of three experts, and the evaluation results were determined through deliberation.

[0114] (Test example 1: Discharge properties) The hair styling product was dispensed from the aerosol container onto the palm of the hand for 1 second. The dispensing performance was evaluated according to the following criteria.

[0115] <Evaluation Criteria for Discharge Performance> ○: Can be dispensed in a foamy (bubble-like) form. ×: Cannot be dispensed in a foamy (bubble) form.

[0116] In Comparative Examples 2, 6-8, the hair styling product composition solidified because the ingredients could not be emulsified, so no further evaluation was performed.

[0117] Furthermore, in the aerosol spray hair styling agent obtained in Comparative Example 9, the hair styling agent composition could be dispensed from the aerosol container in a spray (mist) form.

[0118] (Test example 2: Hair styling ability for permed hairstyles) In the aerosol foam hair styling agents obtained in Examples and Comparative Examples 1,3-5, approximately 2g of the hair styling agent composition was dispensed from the aerosol container onto the palm of the hand. The dispensed hair styling agent composition was then evenly applied to approximately one-third of the entire head of a medium-length wig (manufactured by Eucalyptus Japan Co., Ltd.), and the hair was styled by gripping it. The entire head of the wig was styled by repeating the above process from dispensing the hair styling agent composition to styling a total of three times (styling approximately one-third of the entire head a total of three times).

[0119] In Comparative Example 9, the aerosol spray hair styling agent obtained was applied by spraying the hair styling agent composition directly onto approximately one-third of the hair of a medium-length wig (manufactured by Eucalyptus Japan Co., Ltd.) from the aerosol container, and the hair was styled by gripping it. The entire wig was styled by repeating the above process of spraying the hair styling agent composition and styling a total of three times (styling approximately one-third of the hair of the entire wig a total of three times).

[0120] As described above, the wigs were styled to resemble perms. The wigs were then visually inspected, and their ability to be styled to resemble perms was evaluated according to the following criteria.

[0121] (1) Styling power to create strong curls in hair. ○ (Excellent): The hair as a whole has fine, strong U-shaped curls, and the hairs appear to be intricately interwoven. △ (Good): The hair has a strong U-shaped curl throughout. × (Poor): The hair does not have a strong U-shaped curl, or only a portion of the surface hairs have a strong U-shaped curl.

[0122] <(2) Hair styling power to lift hair> ○ (Excellent): The hair stands up strongly, and a significant increase in volume is observed throughout the hair. △ (Good): The hair stands up, and there is a clear increase in overall volume. × (Poor): The hair is not standing up at all, or only some of the hair on the surface is standing up.

[0123] <(3) Criteria for evaluating the ability to style permed hair> ○○: The evaluation results for "(1) Hair styling ability to strongly curl hair" and "(2) Hair styling ability to lift hair" were both ○, indicating excellent styling ability for perm-like hairstyles. ○: Of the evaluation results for "(1) Hair styling ability to strongly curl hair" and "(2) Hair styling ability to lift hair," one is ○ and the other is △, indicating good styling ability for perm-like hairstyles. △: The evaluation results for "(1) Hair styling ability to strongly curl hair" and "(2) Hair styling ability to lift hair" were both △, indicating that the styling ability for perm-like hairstyles is moderately good. ×: At least one of the evaluation results for "(1) Hair styling ability to strongly curl hair" and "(2) Hair styling ability to lift hair" is ×, and it is not possible to style the hair into a perm-like hairstyle.

[0124] The composition and results are shown in Tables 1 to 5 below. Figure 1 shows a photograph of a medium-length wig styled into a perm-like hairstyle using the aerosol foam hair styling agent obtained in Example 1. Figure 1(a) is a front view, and Figure 1(b) is a side view. In Comparative Examples 1, 3 to 5, the styling power to curl or lift the hair was inferior, and therefore, it was not possible to style the hair into a perm-like hairstyle. In Comparative Example 9, only some of the surface hair was curled and only some of the surface hair was lifted, and therefore, it was not possible to style the hair into a perm-like hairstyle.

[0126] [Table 2]

[0127] [Table 3]

[0128] [Table 4]

[0129] [Table 5]

[0130] Furthermore, Figure 2 shows an example of hair styling achieved by partially styling the hair using the aerosol foam hair styling agent obtained in Example 1. More specifically, Figure 2 shows an example of hair styling achieved by styling the front of a medium-length wig using the aerosol foam hair styling agent obtained in Example 1. Figure 2(a) is a front view, and Figure 2(b) is a side view. As shown in Figure 2, by using the aerosol foam hair styling agent of the present invention, it is possible to style the hair in a way that is different from a perm by partially styling the hair or by using less force when gripping the hair while styling.
