Specific examples of preservatives include organic acids and their derivatives such as benzoic acid, sodium benzoate, undecylenic acid, salicylic acid, sorbic acid, potassium sorbate, dehydroacetic acid, sodium dehydroacetate, isobutyl parahydroxybenzoate, isopropyl parahydroxybenzoate, ethyl parahydroxybenzoate, butyl parahydroxybenzoate, propyl parahydroxybenzoate, benzyl parahydroxybenzoate, methyl parahydroxybenzoate, sodium methyl parahydroxybenzoate, and methylisothiazolinone; Isopropylmethylphenol, orthophenylphenol, sodium orthophenylphenol, chlorhexidine gluconate solution, chlorthymol, chlorphenesin, chloroxylenol, chlorcresol, dichlorooxylenol, dichlorobenzyl alcohol, thiobischlorophenol, thymol, 6-isopropyl-m-cresol, trichlorocarbanilide, trichlorohydroxydiphenyl ether, sodium phenoxide, parachlorophenol, halocarban, phenethyl alcohol, phenoxyethanol, phenol, hexachlorophene, and other phenols; Quaternary ammonium salts such as stearyldimethylbenzylammonium chloride, stearyltrimethylammonium chloride, cetyltrimethylammonium chloride, cetylpyridinium chloride, benzalkonium chloride, benzethonium chloride, lauryltrimethylammonium chloride, laurylpyridinium chloride, alkylisoquinolinium bromide solution, cetyltrimethylammonium bromide, domiphen bromide, lauryltrimethylammonium bromide, and cetyltrimethylammonium saccharin; Amphoteric surfactants such as alkyldiaminoethylglycine hydrochloride and sodium lauryldiaminoethylglycine; Photosensitizers such as photosensitizer 101, photosensitizer 201, photosensitizer 401, and p-dimethylaminostyrylepylmethylthiazolium iodide; Plant extracts such as tea extract and hinokitiol; and Other preservatives such as silver-copper zeolite, glutaraldehyde, chloramine T, chlorhexidine, dibromopropamidine diisothionate, zinc pyrithione, sodium trichlorohydroxydiphenyl ether pyrithione, 5-bromo-5-nitro-1,3-dioxane, and polyaminopropyl biguanide; and one or more compounds selected from the group consisting of compounds other than those listed above that have antiseptic or bactericidal effects. Specific examples of compounds other than those listed above that have antiseptic or bactericidal effects include EDTA-2Na, sodium dehydroacetate, propylene glycol, benzyl alcohol, 1,3-butylene glycol, and dipropylene glycol.

[0045] From the viewpoint of improving the shelf life of the hair cosmetic, the amount of preservatives in the hair cosmetic is preferably 0.01% by mass or more, more preferably 0.1% by mass or more, and even more preferably 0.5% by mass or more, relative to the total amount of the hair cosmetic. Furthermore, from the viewpoint of ensuring shelf life without impairing the feel of the hair cosmetic, the amount of preservatives in the hair cosmetic is preferably 5% by mass or less, more preferably 3% by mass or less, and even more preferably 2% by mass or less, relative to the total amount of the hair cosmetic.

[0046] Furthermore, hair cosmetics may contain ingredients that are typically included in hair cosmetics, as appropriate. Examples of such ingredients include anti-dandruff agents; vitamins; disinfectants; anti-inflammatory agents; preservatives; chelating agents; moisturizers such as sorbitol; colorants such as dyes and pigments; extracts; pearlescent agents; fragrances; UV absorbers; antioxidants; photocatalysts; shea butter; rose water; sunflower oil; orange oil; eucalyptus oil; hydrocarbon oils such as (C13-16) isoparaffin; and surfactants. Examples of photocatalysts include metal oxides such as titanium dioxide and tungsten oxide, aromatic hydroxy compounds such as 8-hydroxyquinoline, 7-cyano-2-naphthol, and 8-quinolinol-1-oxide, as well as other sulfonated pyrene compounds, onium salts, diazomethane derivatives, bissulfone derivatives, disulfonate derivatives, nitrobenzyl sulfonate derivatives, sulfonic acid ester derivatives, and sulfonic acid esters of N-hydroxyimide. Any of the following surfactants can be used: cationic surfactants, anionic surfactants, amphoteric surfactants, and nonionic surfactants.

Anionic surfactants include alkyl sulfonates, alkyl carboxylates, alkyl ether sulfonates, and alkyl ether carboxylates. Amphoteric surfactants include imidazoline, carbobetine, amidebetaine, sulfobetaine, hydroxysulfobetaine, and amidesulfobetaine. Nonionic surfactants include esters such as glycerin fatty acid esters, sorbitan fatty acid esters, and sucrose fatty acid esters, as well as ethers such as polyoxyethylene alkyl ethers, polyoxyethylene alkylphenyl ethers, polyoxyethylene-polyoxypropylene alkyl ethers, and polyoxyethylene-polyoxypropylene alkylphenyl ethers.

[0047] On the other hand, from the viewpoint of suppressing discoloration of hair cosmetics, it is preferable that hair cosmetics do not contain coloring components. From the same viewpoint, the content of coloring components in hair cosmetics is preferably 0.1% by mass or less, more preferably 0.05% by mass or less, even more preferably 0.01% by mass or less, and even more preferably 0% by mass, relative to the total amount of hair cosmetics. From a similar viewpoint, the hair cosmetic is preferably transparent or white to milky white, and more preferably colorless and transparent.

[0048] Next, we will explain the manufacturing method for hair cosmetics. Hair cosmetic compositions can be obtained, for example, by blending components (A) to (C) and other components as appropriate in a predetermined order. More specifically, it is preferable to blend water and a solvent other than water, and then blend components (A) to (C) and other components as appropriate. Heating and stirring may also be performed as needed.

[0049] The hair cosmetic obtained in this embodiment is contained in a container of an applicator and applied using an applicator. The configuration of the applicator will be described below.

[0050] (Applicator) In this embodiment, the applicator is preferably of the mascara type. Figure 1 is a cross-sectional view showing an example of the configuration of the applicator in this embodiment. Figures 2 and 3 are cross-sectional views showing the configuration of the container 2 and lid 3 in the applicator 1 shown in Figure 1, respectively. The applicator 1 shown in Figures 1 to 3 has a container 2 containing hair cosmetic C and a lid 3. The lid 3 comprises an applicator shaft 41, an applicator 42 provided at one end of the applicator shaft 41, and a container lid portion 31 provided at the other end of the applicator shaft 41. In the applicator 1 shown in Figure 1, when the lid is closed, at least a portion of the applicator 42 is immersed in the hair cosmetic C in the container 2. In addition, a wiping member 5 is provided on the inner circumference of the mouth 22 of the container 2 to wipe off any hair cosmetic C adhering to the applicator 42 when attaching or detaching the lid 3.

[0051] As shown in Figure 2, the container 2 is provided with a compartment 21 for storing the hair cosmetic C, a mouth 22 that opens at its top, and a connecting portion 23 that extends downward from the mouth 22. The shape of the compartment 21 is a bottomed cylinder, and may be, for example, roughly cylindrical or prismatic. The opening 22 has a constricted shape. The outer circumference of the opening 22 is provided with a male threaded portion 24 that screws into the female threaded portion 34 (Figure 3) of the inner circumference 32 of the lid 3. The connecting portion 23 is integrally formed with the opening portion 22 and is the part that fits onto the upper part of the inner circumference of the housing portion 21 via the wiping body 53 and wiping fitting portion 52 of the wiping member 5. The lower part of the outer circumference of the connecting portion 23 is constricted, and a gap is formed between the outer circumference of the connecting portion 23 and the inner circumference of the housing portion 21 into which the wiping fitting portion 52 is fitted.

[0052] For example, the container 2 may be made of an aluminum alloy for the storage section 21, and polypropylene (PP) for the opening section 22 and connecting section 23.

[0053] The wiping member 5 (Figure 2) is a member that wipes off the hair cosmetic C adhering to the applicator 42 when attaching or detaching the lid 3, and has a wiping body 53, a wiping flange 51, and a wiping fitting part 52. The wiping body 53 is a part that is inscribed within the inner circumference of the connecting portion 23 of the container 2. The wiping body 53 has, for example, a substantially cylindrical shape with an open top and bottom.

[0054] The wiping flange 51 is a flange-shaped portion that contacts and wiping the coating body 42. The wiping flange 51 is formed in a tapered, roughly conical shape that extends inward and downward from the upper edge of the wiping body 53, and the wiping hole 51A is formed in its tapered portion. The diameter of the wiping hole 51A is set to be smaller than the outer diameter of the coating body 42 and the coating shaft 41. With this configuration, the wiping flange 51 elastically adheres to the outer surfaces of the coating body 42 and the coating shaft 41 at the inner peripheral edge portion of the wiping hole 51A. The cross-sectional shape and cross-sectional area (diameter) of the wiping hole 51A are set appropriately according to the cross-sectional shape, cross-sectional area, material, rigidity, and required wiping performance of the coating body 42 and coating shaft 41.

[0055] The fitting portion 52 is a part that fits between the inner circumference of the housing portion 21 of the container 2 and the outer circumference of the connecting portion 23, and has a cross-sectional shape that extends from the inner circumference of the connecting portion 23 of the container 2 through the lower edge to the outer circumference. In the example of Figure 2, the fitting portion 52 is sandwiched and fitted in the gap between the lower part of the outer circumference of the connecting portion 23 and the inner circumference of the housing portion 21. As a result, the housing portion 21 and the connecting portion 23 are fixed together via the wiping fitting portion 52. Furthermore, the wiping body 53 is fixed to the inner circumference of the connecting portion 23 via the wiping fitting portion 52, and the wiping flange portion 51 is fixed to the lower edge of the inner circumference of the mouth portion 22 such that it forms a tapered shape from the upper edge of the wiping body 53 toward the inner and downward, in other words, it forms a tapered shape from the lower edge of the inner circumference of the mouth portion 22 toward the inner and downward.

[0056] Here, "the wiping member 5 is provided on the inner circumference of the mouth 22 of the container 2" is determined based on the wiping flange 51, and includes forms in which parts other than the wiping flange 51, specifically the wiping body 53 and the wiping fitting part 52, are not located on the inner circumference of the mouth 22 of the container 2, as in this embodiment.

[0057] The material of the wiping member 5 can be, for example, nitrile rubber (NBR rubber) or polybutylene terephthalate copolymerized with soft segments.

[0058] Next, the lid 3 will be described. The container lid portion 31, which is the main body of the lid 3, has a cylindrical shape with a top surface and an open bottom, as shown in Figure 3, and is designed to be integrated with the container 2 when closed. A female threaded portion 34 is formed at the lower part of the inner circumference portion 32 of the container lid portion 31, which screws into the male threaded portion 24 of the mouth portion 22 of the container 2. The container lid portion 31 is fixed to the mouth portion 22 of the container 2 when closed by screwing the female threaded portion 34 and the male threaded portion 24 together. PP is one example of a material for the container lid portion 31.

[0059] As shown in Figure 3, the hair cosmetic application member 4 constitutes a part of the lid 3 and has an application shaft 41, an application body 42, a spreading member 6, and a fixing part 44. The fixing portion 44 is a part that is fitted and fixed to the upper part of the inner circumference 32 of the lid 3. The coating shaft 41 is a shaft that supports the coating body 42 and is fixed to the inner circumference 32 of the cover body 3 via a fixing part 44. The material of the coating shaft 41 may be, for example, PP.

[0060] The applicator 42 is located at the tip (lower end in the figure) of the applicator shaft 41, and is designed to apply the hair cosmetic C attached to the applicator 42 to the hair, which is the object to be applied. The applicator is preferably a brush. Examples of the shape of the applicator 42 include a conical shape, a frustoconical shape, a hemispherical shape, a semi-elongated sphere shape, a cylindrical shape, a bullet shape, and a combination of two or more of these. From the viewpoint of more selectively applying the hair cosmetic to desired areas of the hair, the applicator 42 preferably has a shape that widens from the tip to the rear end, more preferably a brush having a conical shape, a frustoconical shape, or a shape that combines any of these with a cylindrical shape, and even more preferably a frustoconical brush.

[0061] Figure 4 is a cross-sectional view showing an example of the configuration of a brush-like applicator 42. In Figure 4, the applicator 42 has a core wire portion 71 and a bristle 72. In the applicator 42, the shape of the brush portion is a frustoconical shape. The core wire section 71 is composed of, for example, a pair of metal core wires twisted together in a spiral shape. Bristol 72 extends evenly and radially in the circumferential direction of the core wire portion 71 and is uniformly dispersed in a spiral pattern in the axial direction of the core wire portion 71. Bristol's materials are synthetic resin fibers such as nylon 6, nylon 66, and polyethylene terephthalate (PET).

[0062] When the brush diameter of the coating body 42 is defined as the diameter of its widest part, the brush diameter is preferably 1 mm or more, and more preferably 3 mm or more, from the viewpoint of appropriately increasing the amount of liquid carried on the coating body 42. Furthermore, from the viewpoint of suppressing dripping from the coating body 42, the brush diameter of the coating body 42 is preferably 20 mm or less, and more preferably 12 mm or less.

[0063] Furthermore, if the applicator 42 has a tip surface such as a frustoconical shape, the brush diameter at the tip of the applicator 42 is preferably 2.5 mm or more, more preferably 3 mm or more, and preferably 7 mm or less, and more preferably 6 mm or less, from the viewpoint of making it easier to adhere the applicator to the hair bundle. On the other hand, the brush diameter at the rear end of the coating body 42 is preferably 8 mm or more, more preferably 9 mm or more, preferably 20 mm or less, more preferably 12 mm or less, and even more preferably 11 mm or less, from the viewpoint of brush operability.

[0064] The brush length of the coating body 42 is preferably 25 mm or more, more preferably 30 mm or more, and preferably 45 mm or less, and more preferably 40 mm or less, from the viewpoint of more stably producing the desired bristle bundles.

[0065] Furthermore, in the applicator 42, from the viewpoint of firmly transferring the hair cosmetic to the hair bundle, it is preferable that the shape of the fiber cross-section of Bristol 72 differs between the tip Q and the rear end P. More preferably, at the tip Q, Bristol 72 is hollow, i.e., the cross-sectional shape of Bristol 72 is annular, such as a ring, and at the rear end P, the cross-sectional shape of Bristol 72 is clover-shaped. Here, the tip Q of the coated body 42 is the region from the tip of the coated body 42 in the direction of extension of the core wire portion 71, for example, up to 20 mm, preferably up to 18 mm, more preferably up to 16 mm, and even more preferably up to 14 mm.

[0066] Returning to Figure 3, the expanding member 6 is provided on the coating shaft 41 and is configured to expand the wiping holes 51A during the closing process and to maintain the expanded state of the wiping holes 51A when the lid is closed. In the example shown in Figure 3, the expanding member 6 is provided between the coating body 42 and the fixing part 44 on the coating shaft 41, and is fitted into the narrow diameter portion 41A of the coating shaft 41 using the through hole that penetrates it vertically. The expanding member 6 can be inserted from the lower end side of the coating shaft 41 and fitted into the narrow diameter portion 41A before attaching the coating body 42 to the coating shaft 41, with the through hole stretched radially. The material of the expanding member 6 can be, for example, the same material as the wiping member 5.

[0067] The expanding member 6 has a first expanding portion 61 at the bottom and a second expanding portion 62 at the top, and a constricted portion 63 between the two expanding portions that is narrower than the two expanding portions. The first expanding portion 61 is a flange-shaped part provided at the lower part of the expanding member 6 so as to extend outward. The first expanding portion 61 has an outer circumference shape that is slightly larger than the cutting hole 51A of the cutting flange portion 51 of the cutting member 5. Therefore, during the closing process, it is possible to press the cutting flange portion 51 downward and expand the cutting hole 51A of the cutting flange portion 51. In this embodiment, the outer end of the first expanding portion 61 is pointed.

[0068] Furthermore, the expanding member 6 is configured such that, when the lid is closed, the expanded state of the squeezing hole 51A can be maintained by the outer circumference of the bulging second expanding portion 62. In detail, the second expanding portion 62 is a part provided on the upper part of the expanding member 6, and the outer circumference of the second expanding portion 62 bulges outward and downward, and has a shape that is slightly larger than the shape of the inner circumference of the squeezing flange portion 51 of the squeezing member 5. Also, the outer circumference of the second expanding portion 62 has a shape that is slightly larger than the shape of the inner circumference of the mouth portion 22 of the container 2.

[0069] Therefore, the outer circumference of the bulging second expanding portion 62 can press the wiping flange portion 51 downward during the closing process, thereby expanding the wiping hole 51A of the wiping flange portion 51. Furthermore, even when the lid is closed (in a completely closed state), it can press the wiping flange portion 51 downward, maintaining the expanded state of the wiping hole 51A. Here, "expanded state of the wiping hole 51A" refers to a state in which the peripheral edge of the wiping hole 51A is separated from the hair cosmetic application member 4 (in this embodiment, the expanding member 6).

[0070] Furthermore, during the closing process, the bulging outer circumference of the second spreading portion 62 adheres closely to the inner circumference of the wiping flange portion 51 and the inner circumference of the mouth portion 22 of the container 2, allowing it to scrape off any hair cosmetic product adhering to the inner circumference of the wiping flange portion 51 and the inner circumference of the mouth portion 22 of the container 2. The scraping effect of the hair cosmetic product C is further enhanced when the outer circumference of the second spreading portion 62 makes planar contact with the inner circumference of the wiping flange portion 51 and the inner circumference of the mouth portion 22 of the container 2.

[0071] In the hair cosmetic application member 4, the application body 42 is located below the opening at the bottom of the container lid 31, so that, as shown in Figure 1, when the lid is closed, the application body 42 is immersed in the hair cosmetic C contained in the container 2.

[0072] As shown in Figure 1, a packing 33 is provided on the lid 3 at the portion that contacts the upper edge of the opening 22 of the container 2 when the lid is closed. The packing 33 improves the airtightness between the container 2 and the lid 3 when the lid is closed. In this embodiment, the packing 33 is made of, for example, nitrile rubber (NBR rubber) and is fitted into the narrow diameter portion at the bottom of the fixing portion 44.

[0073] When using the applicator 1, if the lid 3 is removed upward from the container 2 from the closed position, the hair cosmetic application member 4 also moves upward. At this time, the outer surfaces of the application shaft 41 and the application body 42 are wiped by the wiping flange 51 of the wiping member 5, in that order. As a result, even if there is an excess of hair cosmetic C attached to the application body 42 and the application shaft 41, the attached hair cosmetic C is wiped off, and the appropriate amount of hair cosmetic C is attached. The hair cosmetic C can then be applied to the hair using the application body 42.

[0074] In this embodiment, the hair cosmetic is used, for example, preferably on the bangs, around the face, or on the top of the head. The hair cosmetic is also used on one or more of the stray hairs and flyaway hairs. Furthermore, the hair styling method in this embodiment includes applying the hair cosmetic in this embodiment to the hair, preferably to the bangs, around the face, or on the top of the head. For example, by applying the hair cosmetic of this embodiment to the bangs, around the face, or the sides of the crown, a desired styling effect can be obtained around the face, and a desired texture, shine, and natural finish can be achieved. Furthermore, by applying the hair cosmetic of this embodiment to stray hairs or flyaways, it is possible to easily tidy up areas where the hairstyle is a concern, such as lifting the hair or taming flyaways. Furthermore, by using the hair cosmetic of this embodiment, it is possible to obtain a desirable finish without a white cast, for example. It is also possible to suppress stickiness in the hair to which the hair cosmetic has been applied, for example, at the ends of the hair. Furthermore, by using the hair cosmetic of this embodiment, the longevity of the finish can be improved. Furthermore, according to this embodiment, it is possible to obtain a hair cosmetic in which foaming is suppressed when the applied product is returned to the container.

[0075] The embodiments of the present invention have been described above, but these are merely examples, and various other configurations can also be adopted. [Examples]

[0076] (Examples 1-10, Comparative Examples 1-5) Hair styling kits comprising hair cosmetics and applicators with the compositions shown in Tables 1 and 2 were prepared and evaluated.

[0077] (Method for preparing hair cosmetic products) Water and ethanol were pre-weighed into a beaker and heated to 65°C while stirring with a stirrer. Then, according to the formulations described in Tables 1 and 2, components (A), (B), and (C) were added in that order and stirred. After cooling to room temperature, the hair cosmetic formulations for each example were obtained. The viscosity of the obtained hair cosmetic was measured by the following method. (Method for measuring viscosity) The viscosity of the hair cosmetic was measured using a TVB-10 viscometer manufactured by Toki Sangyo Co., Ltd. The liquid temperature was preheated to 30°C, and approximately 80g of the sample was placed in a screw-cap tube. The viscosity was then measured using the rotor type and rotation speed described in Tables 1 and 2. The viscosity of the hair cosmetic in each example, as well as the type and rotation speed of the rotor used in each example, are shown in Tables 1 and 2.

[0078] (Applicator: Mascara) In all examples except Comparative Examples 1 and 2, an applicator having a mascara brush-shaped applicator as shown in Figure 4 was used. The shapes and sizes of the applicators used are shown in Tables 1 and 2. In the frustoconical applicator, the shape of the fiber cross-section differed between the tip Q and the rear end P. The cross-sectional shape of the tip Q (up to 14 mm from the tip) was hollow, while the rear end P used a clover-shaped cross-section. On the other hand, the cross-sectional shape of the fibers in the bullet-shaped applicator was clover-shaped.

[0079] (Evaluation method) The hair cosmetic obtained in each example was applied and evaluated according to the following evaluation items and criteria. In (1) to (6) and (10) below, a hair trace measuring 6 cm wide, 10 cm long, and 5 g in mass was used, and the hair strands were divided into approximately 1 cm intervals. Using an applicator, the hair cosmetic was applied to the front and back surfaces of the hair strands, one stroke at a time, from the root to the tip of the trace, and the ends were lightly styled. This action was repeated a total of six times, corresponding to the width of the trace, to apply a total of 0.6 grams of hair cosmetic. In Comparative Example 1, the hair cosmetic was applied by hand without using an applicator. In Comparative Example 2, a pump mist container (manufactured by Yoshino Kogyo Co., Ltd., pump dispenser: YSR, tip: 0.3J) was filled with the hair cosmetic and used as an applicator. In both cases, the same hair tracer as above was used, the hair bundles were divided in the same way as above, a total of 0.6 grams of hair cosmetic was applied to the front and back surfaces of the hair bundles, and then spread with fingers.

[0080] (1) Ease of making bundles The ease with which hair bundles could be formed after application was evaluated by visual observation. The evaluation was conducted by seven panelists using the following four-point scale.

The total scores are shown in Tables 1 and 2. 4 "Flyaway hairs are well controlled" / 3 "Flyaway hairs are controlled" / 2 "Some flyaway hairs are present" / 1 "Flyaway hairs do not subside".

[0086] (7) The bangs can be styled upwards. A Regina 925N wig with the bangs cut to 10 cm was used for evaluation. The bangs were divided approximately in half from the center of the eyes on the wig, and 0.5 g of hair cosmetic was applied to the divided bangs using an applicator, and the bangs were lifted towards the crown of the head. In Comparative Example 1 and Comparative Example 2, 0.5 g of hair cosmetic was applied by hand or from the aforementioned pump mist container, spread with fingers after application, and the bangs were lifted towards the crown of the head. Immediately after application, the ability to lift the bangs was evaluated by visual observation. The evaluation was conducted by seven panelists using the following four-point scale. The total evaluation scores are shown in Tables 1 and 2. 4 "Can easily style bangs upwards" / 3 "Can style bangs upwards" / 2 "Bangs don't stand up very well" / 1 "Bangs don't stand up at all"

[0087] (8) Less likely to leave a white cast The wig, after the bangs were styled as described in (7) above, was used to evaluate how easily it would appear white or unnatural. The evaluation was conducted by seven panelists using the following four-point scale. The total scores are shown in Tables 1 and 2. 4 "White cast is well suppressed" / 3 "White cast is suppressed" / 2 "Slight white cast is present" / 1 "White cast is present"

[0088] (9) Foaming properties when the coated material is returned to the container The foaming properties of the liquid in the opening 22 were evaluated by visually observing the foaming behavior after the coated material 42 was removed from the container 2 and returned to the container 2's receiving section (mouth 22) three times. The evaluation was performed by seven panelists using the following four-level scale. The total scores are shown in Tables 1 and 2.
