Description

[Technical field]

[0001] The present invention relates to a hair styling composition and a hair styling method using said hair styling composition. [Background technology]

[0002] Hair styling compositions containing various ingredients are provided for various hair styling purposes. As an example of the hair styling composition, a technology has been proposed (Patent Document 1) for improving hair styling properties, such as by adding ingredients such as carnauba wax. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2009-013125 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in order to improve hair styling properties such as forming hair bundles and giving manageability to hair tips, solid oils (oils that are solid at 25°C) such as waxes and hydrocarbons that increase adhesion between hair strands may be used in hair styling compositions. However, even if the above-mentioned solid oils are blended, depending on the physical properties of the hair styling composition, the improvement in hair styling properties such as forming hair bundles may be insufficient, and the desired hair styling properties may not be obtained. In particular, when the viscosity of the hair styling composition is relatively low, there is a problem that the hair styling properties such as forming hair bundles and giving manageability to hair tips cannot be fully exhibited.

[0005] In view of the above problems, an object of the present invention is to increase the viscosity of a hair styling composition containing a solid oil. [Means for solving the problem]

[0006] The present inventors have conducted intensive research into the above-mentioned problems and have found that a hair styling composition with increased viscosity can be provided by blending a hair styling composition containing an oil that is liquid at 25°C with 4% by mass or more of sunflower seed wax, which is a solid oil, or 2% by mass or more of rice bran wax having an iodine value of 3.0 or less.

[0007] That is, the hair styling composition of the present invention comprises: (A1) 4% by mass or more of sunflower seed wax or (A2) 2% by mass or more of rice bran wax having an iodine value of 3.0 or less, and (B) Oil that is liquid at 25°C This is a hair styling composition containing

[0008] The hair styling composition of the present invention preferably has a viscosity of 50 Pa·S or more, since this further improves the hair styling properties.

[0009] The hair styling composition of the present invention is preferably one in which the blending amount of (A1) sunflower seed wax is 25 mass% or less, or the blending amount of (A2) rice bran wax having an iodine value of 3.0 or less is 25 mass% or less, since this makes the composition easier to apply to hair.

[0010] In the hair styling composition of the present invention, the oil (B) that is liquid at 25°C is preferably one or more oils selected from liquid hydrocarbons, liquid ester oils, liquid oils and fats, or liquid silicone oils, as this further improves the shine of the hair after styling.

[0011] The hair styling composition of the present invention preferably contains (B) an oil that is liquid at 25° C. in an amount of 15% by mass or more, since this makes the composition easier to apply to hair.

[0012] The hair styling composition of the present invention is preferably one that contains a nonionic surfactant (C) since this provides excellent washability.

[0013] The hair styling composition of the present invention is preferably in a solid form, since this provides a more excellent improvement in hair styling properties.

[0014] The hair styling method using the hair styling composition of the present invention provides excellent hair styling properties. Effect of the Invention

[0015] According to the present invention, it is possible to increase the viscosity of a hair styling composition, and also to provide a hair styling method using the hair styling composition of the present invention. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] The present invention will be described below based on the embodiments of the present invention.

[0018] The hair styling composition of the present embodiment comprises (A1) 4% by mass or more of sunflower seed wax or (A2) 2% by mass or more of rice bran wax having an iodine value of 3.0 or less, and (B) Oil that is liquid at 25°C This is a hair styling composition containing

[0019] In the following description, "sunflower seed wax" may be referred to as component (A1), "rice bran wax with an iodine value of 3.0 or less" as component (A2), and "oil that is liquid at 25°C" as component (B).

[0020] <(A1) component, (A2) component> The hair styling composition of the present embodiment contains 4% by mass or more of sunflower seed wax (A1), component, or 2% by mass or more of rice bran wax having an iodine value of 3.0 or less (A2), component. The hair styling composition of this embodiment may contain both the (A1) and (A2) components. Therefore, the hair styling composition of this embodiment may contain the (A2) component as long as the amount of the (A1) component is 4% by mass or more, or the hair styling composition of this embodiment may contain the (A1) component as long as the amount of the (A2) component is 2% by mass or more.

[0021] [(A1) Sunflower seed wax] The sunflower seed wax blended in the hair styling composition of the present embodiment is a wax obtained from the seeds of sunflower (HELIANTHUS ANNUUS). Blending sunflower seed wax in the hair styling composition of the present embodiment provides excellent improvement in the viscosity of the hair styling composition.

[0022] The amount of sunflower seed wax blended in the hair styling composition of this embodiment is 4% by mass or more. By making the amount of sunflower seed wax blended 4% by mass or more, the viscosity of the hair styling composition can be further increased. In addition, by increasing the viscosity of the hair styling composition, a hair styling composition with improved hair styling properties can be realized. Here, "hair styling properties" refers to the hair styling action of forming hair bundles and imparting manageability to the ends of hair (hereinafter, "hair styling properties" will be used in the same sense).

[0023] The lower limit of the amount of sunflower seed wax to be blended in the hair styling composition of this embodiment is 4 mass% or more, preferably 5 mass% or more, more preferably 6 mass% or more, even more preferably 8 mass% or more, and particularly preferably 9 mass% or more, from the viewpoint of further increasing the viscosity of the hair styling composition.

[0024] The upper limit of the amount of sunflower seed wax to be blended in the hair styling composition of the present embodiment is not particularly limited. In addition, the upper limit of the amount is preferably 25% by mass or less, more preferably 20% by mass or less, and even more preferably 15% by mass or less, from the viewpoint of making it easier to apply to hair.

The smaller the iodine value, the fewer the amount of unsaturated groups (the fewer the number of double bonds) in the sample (rice bran wax).

[0027] The rice bran wax having an iodine value of 3.0 or less may be a commercially available product, or may be a rice bran wax having an iodine value of more than 3.0 that has been refined by a known method to have an iodine value of 3.0 or less. An example of the commercially available product is TOWAX-3P3 manufactured by Toa Chemical Industry Co., Ltd.

[0028] The amount of rice bran wax having an iodine value of 3.0 or less blended in the hair styling composition of this embodiment is 2% by mass or more. By making the amount of rice bran wax having an iodine value of 3.0 or less 2% by mass or more, the viscosity of the hair styling composition can be increased. By increasing the viscosity of the hair styling composition, it is possible to realize a hair styling composition with improved hair styling properties.

The viscosity measurement was performed using a stress-controlled rheometer "Rheo Stress 6000" manufactured by HAAKE, under the following measurement conditions: measurement temperature: 25°C, diameter of the cone-plate sensor: 35 mm, inclination angle of the cone-plate sensor: 2°, in flow curve mode, measurement time: 300 seconds, shear rate: 0.01 s -1 From 100s -1 When the shear rate is changed to 1s -1The viscosity was not measured for Comparative Example 1, which was evaluated as "separated" in the evaluation of the appearance of the composition, because it was thought that an accurate viscosity measurement value could not be obtained. Moreover, the hair styling compositions of Examples 1 to 4 and Comparative Example 1 were evaluated for "storage stability" and "appearance" according to the following evaluation methods and criteria.

[0068] (Evaluation method for storage stability) About 30 g of each of the prepared hair styling compositions of Examples 1 to 4 and Comparative Example 1 was placed in a storage container (a transparent sealed jar capable of holding 50 g of a hair styling composition) and stored for one month in an incubator at 50° C. After one month had passed, each storage container containing the hair styling composition of Examples 1 to 4 and Comparative Example 1 was removed from the incubator at 50° C., and the state of each hair styling composition immediately after opening the lid of the storage container was visually observed according to the following evaluation criteria.

[0069] (Evaluation criteria for storage stability) ◯: No oil floating is observed on the surface of the hair styling composition. ×: Oil floating is observed on the surface of the hair styling composition.

[0070] (Appearance evaluation method) The hair styling compositions of Examples 1 to 4 and Comparative Example 1 that were placed in the storage containers immediately after preparation were visually observed according to the following evaluation criteria.

[0071] (Appearance Evaluation Criteria) Solid state: When a container containing the hair styling composition is tilted at an angle of about 45 degrees, the hair styling composition does not flow immediately thereafter until 3 seconds have elapsed. Liquid state: After a container containing the hair styling composition is tilted at an angle of about 45 degrees, the hair styling composition flows within 3 seconds after the tilt. Separation: The hair styling composition contained in the container separates (the solid composition and the liquid composition are present in an unevenly separated state).

[0072] (Evaluation Results) Table 1 below shows the components used, as well as the evaluation results of the hair styling compositions of Examples 1 to 4 and Comparative Example 1. The numerical value of each component in Table 1 is in mass %. Additionally, in the viscosity evaluation, "-" indicates that the viscosity was not measured.

[0073] [Table 1]

[0074] From the results shown in Table 1, it can be seen that the hair styling compositions of Examples 1 to 4, which contain 4% by mass or more of sunflower seed wax as component (A1) and component (B), have improved viscosities compared to the hair styling composition of Comparative Example 1. Note that, since the hair styling composition of Comparative Example 1 flowed immediately after the container containing the separated Comparative Example 1 was tilted at an angle of about 45 degrees and within 3 seconds, the viscosity of Comparative Example 1 was lower than that of Examples 1 to 4. Furthermore, it can be seen from the results shown in Table 1 that the hair styling compositions of Examples 2 to 4 had superior storage stability at 50°C for 1 month compared to the hair styling compositions of Example 1 and Comparative Example 1.

[0075] (Examples 5 to 13) The hair styling compositions prepared in Examples 5 to 13 were used to evaluate "viscosity measurement," "storage stability," and "appearance" in the same manner as the hair styling compositions in Examples 1 to 4 and Comparative Example 1 in Table 1.

[0076] (Evaluation Results) Table 2 below shows the evaluation results of the hair styling compositions of Examples 5 to 10, along with the blended components. Table 3 below shows the evaluation results of the hair styling compositions of Examples 11 to 13, along with the blended components. Note that the numerical values ​​for each component in Tables 2 and 3 are in mass %, and "-" indicates that the component is not blended.

[0077] [Table 2]

[0078] [Table 3]

[0079] From the results shown in Tables 2 and 3, it can be seen that when the sunflower seed wax, component (A1), is 4 mass% or more and liquid paraffin, 2-ethylhexyl palmitate or decamethylcyclopentasiloxane is used as component (B), the viscosity tends to increase as the amount of sunflower seed wax increases (Comparison between Examples 5 to 7, Examples 8 to 10, and Examples 11 to 13). Moreover, it can be seen from the results shown in Tables 2 and 3 that the hair styling compositions of Examples 5 to 13 had excellent storage stability at 50° C. for 1 month.

[0080] (Example 2, Comparative Examples 2 to 6) The hair styling compositions prepared in Example 2 and Comparative Examples 2 to 6 were used to evaluate "viscosity measurement," "storage stability," and "appearance" in the same manner as for the hair styling compositions in Examples 1 to 4 and Comparative Example 1 in Table 1. In addition, in Comparative Example 2, the appearance was evaluated as "separated", so similarly to Comparative Example 1, the viscosity was not measured.

[0081] (Evaluation Results) Table 4 below shows the evaluation results of the hair styling compositions of Example 2 and Comparative Examples 2 to 6, along with the blended components. The numerical value of each component in Table 4 is % by mass, and "-" indicates that the component was not blended. Additionally, "-" in the viscosity evaluation indicates that the component was not measured.

[0082] [Table 4]

[0083] From the results shown in Table 4, the hair styling compositions of Comparative Examples 3 to 6 had lower viscosities than Example 2. Note that after the container containing the separated Comparative Example 2 was tilted at an angle of about 45 degrees, the hair styling composition of Comparative Example 2 flowed between immediately after and 3 seconds after the tilt, and thus Comparative Example 2 had a lower viscosity than Example 2. It can therefore be seen that the hair styling composition containing 5 mass % sunflower seed wax (Example 2) is superior in increasing the viscosity of the hair styling composition compared to the hair styling compositions containing solid oils other than sunflower seed wax (Comparative Examples 2 to 6). Moreover, it can be seen from the results shown in Table 4 that the hair styling compositions of Comparative Examples 2 to 6 are inferior to Example 1 in storage stability at 50° C. for one month.

[0084] (Examples 14 to 19, Comparative Example 7) The prepared hair styling compositions of Examples 14 to 19 and Comparative Example 7 were used to evaluate "viscosity measurement," "storage stability," and "appearance" in the same manner as the hair styling compositions of Examples 1 to 4 and Comparative Example 1 in Table 1. Note that, since the evaluation result of storage stability in Example 15 was "x," storage stability was not evaluated for Example 14 and Comparative Example 7.

[0085] (Evaluation Results) Table 5 below shows the evaluation results of the hair styling compositions of Examples 14 to 19 and Comparative Example 7, along with the blended components. The numerical value of each component in Table 5 is mass %, and "-" indicates that the component was not blended. Additionally, in the evaluation of storage stability (50°C for 1 month), "-" indicates that the component was not evaluated (Comparative Example 7, Example 14).

[0086] [Table 5]

[0087] The results shown in Table 5 show that the hair styling compositions of Examples 14 to 19, which contain 2% by mass or more of rice bran wax having an iodine value of 3.0 or less (A2) and component (B), have improved viscosity compared to the hair styling composition of Comparative Example 7. Furthermore, from the results shown in Table 5, it can be seen that the hair styling compositions of Examples 16 to 19 had superior storage stability at 50°C for 1 month compared to the hair styling composition of Example 15. The appearance of Examples 14 and 15, which contain 2% by mass and 3% by mass of rice bran wax with an iodine value of 3.0 or less, was solid, but slight oil floating was observed on the surface, so they were evaluated as solid (slightly separated). The appearance of Comparative Example 7 was evaluated as liquid, but slight oil floating was observed on the surface of the composition, so they were evaluated as liquid (slightly separated).

[0088] (Comparative Examples 8 to 12) The hair styling compositions of Comparative Examples 8 to 12 thus prepared were evaluated for "appearance" in the same manner as the hair styling compositions of Examples 1 to 4 and Comparative Example 1 in Table 1. Note that, since the appearance of Comparative Examples 8 to 12 was separated, evaluations of "viscosity measurement" and "storage stability" were not performed.

[0089] (Evaluation Results) Table 6 below shows the evaluation results of the hair styling compositions of Comparative Examples 8 to 12 along with the blended components. The numerical value of each component in Table 6 is mass %, and "-" indicates that the component was not blended. Additionally, "-" in the evaluations of viscosity and storage stability (50°C for 1 month) indicates that the component was not evaluated.

[0090] [Table 6]

[0091] From the results shown in Table 6, the hair styling compositions of Comparative Examples 8 to 12, which contained 3% by mass or more of rice bran wax having an iodine value greater than 3.0 that does not correspond to component (A2) and component (B), were separated. Furthermore, after the containers containing the separated hair styling compositions of Comparative Examples 8 to 12 were tilted at an angle of about 45 degrees, the hair styling compositions of Comparative Examples 8 to 12 flowed immediately after the tilt and within 3 seconds, and thus Comparative Examples 8 to 12 had lower viscosities than Examples 14 to 19.

[0092] (Examples 5 and 17, Comparative Examples 10, 13 to 17) The prepared hair styling compositions of Examples 5 and 17, and Comparative Examples 10, and 13 to 17 were used to evaluate "viscosity measurement," "storage stability," and "appearance" in the same manner as the hair styling compositions of Examples 1 to 4 and Comparative Example 1 in Table 1. Note that for Comparative Example 10, the appearance was separated, so "viscosity measurement" and "storage stability" were not evaluated.

[0093] (Evaluation Results) Tables 7 and 8 below show the evaluation results of the hair styling compositions of Examples 5 and 17, and Comparative Examples 10 and 13 to 17, along with the blended components. The numerical value of each component in Tables 7 and 8 is % by mass, and "-" indicates that the component was not blended. In addition, "-" in the evaluations of viscosity and storage stability (50°C for 1 month) indicates that the component was not evaluated.

[0094] [Table 7]

[0095] [Table 8]

[0096] From the results shown in Tables 7 and 8, the hair styling compositions of Comparative Examples 13 to 17 had lower viscosities than those of Examples 5 and 17. In addition, after the container containing the separated Comparative Example 10 was tilted at an angle of about 45 degrees, the hair styling composition of Comparative Example 10 flowed between immediately after and 3 seconds had elapsed, and Comparative Example 10 had lower viscosity than Examples 5 and 17. Therefore, it can be understood that the hair styling composition (Example 5) containing 5% by mass of sunflower seed wax as component (A1) and the hair styling composition (Example 17) containing 5% by mass of rice bran wax having an iodine value of 3.0 or less as component (A2) are excellent in increasing the viscosity of the hair styling composition compared to the hair styling compositions containing 5% by mass of other waxes or hydrocarbons (Comparative Examples 10, 13 to 17). Moreover, it can be seen from the results shown in Tables 7 and 8 that the hair styling compositions of Comparative Examples 13 to 17 were inferior to Examples 5 and 17 in storage stability. The appearance of Comparative Examples 13 and 14, which contained carnauba wax or candelilla wax, was evaluated as solid (slightly separated) since slight oil floating was observed on the surface of the hair styling composition.

[0097] (Examples 20 and 21) The hair styling compositions of Examples 20 and 21 thus prepared were evaluated for "storage stability" and "appearance" in the same manner as the hair styling compositions of Examples 1 to 4 and Comparative Example 1 in Table 1. In addition, the following evaluations of "rinsing off" and "stickiness" were also performed. The viscosities of the hair styling compositions of Examples 20 and 21 were 50 Pa·S or more.

[0098] (Evaluation of washability and stickiness) The hair styling compositions of Examples 20 and 21 were evaluated for "storage stability" and "appearance" in the same manner as the hair styling compositions of Examples 1 to 4 and Comparative Example 1 in Table 1. In addition, evaluations of "rinsing off" and "stickiness" were performed according to the following evaluation methods and evaluation criteria.

[0099] (Method for evaluating washability) 1 g of the prepared hair styling compositions of Examples 20 and 21 was taken and spread on the palms of both hands. The palms were then washed with running tap water for 5 seconds, and the degree of washing off of the hair styling composition from the palms of both hands (less oily feeling on the palms) was evaluated sensorily according to the following evaluation criteria. The above evaluation was performed by three people who regularly evaluate hair styling compositions, and the evaluation results were obtained by consensus. The hair styling composition used as the evaluation criteria was Example 20.

[0100] (Evaluation criteria for wash-off) ◯: The hair styling composition is better washed off than the standard (palms feel less oily than the standard). Equivalent: The hair styling composition washes off equally well to the standard (oily feeling on the palm is equally well to the standard). ×: The hair styling composition is poorly washed off compared to the standard (palms feel more oily than the standard).

[0101] (Method of evaluating stickiness) 1 g of each of the prepared compositions of Examples 20 and 21 was taken and spread on the palms of both hands. The degree of stickiness when touching one palm with the fingers of the other hand was evaluated sensorily according to the following evaluation criteria. The hair styling composition used as the evaluation criteria was Example 20.

[0102] (Evaluation criteria for stickiness) ○: The palm is less sticky than the standard. Equivalent: Stickiness on palm is equivalent to the standard. ×: The palm is more sticky than the standard.

[0103] (Evaluation Results) Table 9 below shows the evaluation results of the hair styling compositions of Examples 20 and 21 together with the blended components. The numerical value of each component in Table 9 is mass %, and the notation "-" indicates that the component is not blended. Here, the 20E.O. in the polyoxyethylene glyceryl triisostearate (20E.O.) blended in Example 21 indicates that the average number of moles of polyoxyethylene added is 20 (the same applies to Examples 21 to 23 and 26 in Tables 10 to 12 below).

[0104] [Table 9]

[0105] From the results shown in Table 9, the hair styling composition of Example 21 was superior in wash-off properties to the hair styling composition of Example 20. Therefore, it can be understood that the inclusion of polyoxyethylene glyceryl triisostearate (20E.O.), a nonionic surfactant, results in superior wash-off properties.

[0106] (Examples 22 and 23) The prepared hair styling compositions of Examples 22 and 23 were used to evaluate "appearance" in the same manner as the hair styling compositions of Examples 1 to 4 and Comparative Example 1 in Table 1, and were also evaluated for "rinsing off" and "stickiness" in the same manner as the hair styling compositions of Examples 20 and 21 in Table 9 (the hair styling composition used as the standard for evaluation was Example 22). The viscosities of the hair styling compositions of Examples 22 and 23 were 50 Pa·S or more.

[0107] (Evaluation Results) Table 10 below shows the components used and the evaluation results of the hair styling compositions of Examples 22 and 23. The numerical value for each component in Table 10 is mass %, and "-" indicates that the component was not used.

[0108] [Table 10]

[0109] From the results shown in Table 10, the hair styling composition of Example 23 was evaluated as being more excellent in stickiness than the hair styling composition of Example 22. Therefore, it can be understood that the inclusion of water results in a superior stickiness evaluation.

[0110] (Examples 21, 24 to 29) The prepared hair styling compositions of Examples 21 and 24 to 29 were used to evaluate "appearance" in the same manner as the hair styling compositions of Examples 1 to 4 and Comparative Example 1 in Table 1, and were also evaluated for "rinsing off" and "stickiness" in the same manner as the hair styling compositions of Examples 20 and 21 in Table 9. In addition, the "hair styling properties" were evaluated as shown below. The viscosities of the hair styling compositions of Examples 21 and 24 to 29 were 50 Pa·S or more.

[0111] (Evaluation of hair styling) The hair styling compositions of Examples 21 and 24 to 29 were evaluated for "hair styling properties" according to the following evaluation method and criteria.

[0112] (Method for evaluating hair styling properties) The hair styling properties of the prepared Examples 21 and 24 to 29 were evaluated as follows. The wig hair was divided into the left and right halves, 0.5 g of the standard hair styling composition was applied to the left half of the hair, and 0.5 g of a different hair styling composition from the standard was applied to the right half of the hair, and the left and right halves of the hair were respectively styled. Then, the left and right halves of the hair were visually evaluated for the tidyness of the hair ends formed by forming a bundle of hair according to the following evaluation criteria. The above evaluation was performed by three people who regularly evaluate hair styling compositions, and the evaluation results were obtained by consensus. The hair styling composition used as the evaluation criteria was Example 21 in Table 11 and Example 26 in Table 12.

[0113] (Evaluation criteria for hair styling) ○: Compared to the standard, the hair styling properties (the tidying of the hair ends by forming hair bundles) are excellent. Equivalent: Compared to the standard, the hair styling properties (the neatness of the hair ends due to the formation of hair bundles) are equivalent. ×: Compared to the standard, the hair styling properties (the manageability of the hair ends by forming hair bundles) are inferior.

[0114] (Evaluation Results) Tables 11 and 12 below show the evaluation results of the hair styling compositions of Examples 21 and 24 to 29 along with the blended components. The numerical values ​​of each component in Tables 11 and 12 are mass %, and the notation "-" indicates that the component is not blended. Here, "10 E.O." in polyoxyethylene hydrogenated castor oil (10 E.O.) blended in Example 22 in Table 11 and "6 E.O." in polyoxyethylene sorbit beeswax (6 E.O.) blended in Example 23 indicate that the average number of moles of polyoxyethylene added is 10 and 6, respectively.

[0115] [Table 11]

[0116] From the results shown in Table 11, the hair styling composition of Example 21 was superior in the evaluations of wash-off, stickiness, and hair styling properties compared to the hair styling compositions of Examples 24 and 25. Therefore, it can be understood that the inclusion of polyoxyethylene glyceryl triisostearate (20E.O.), among other nonionic surfactants, results in superior evaluations of wash-off, stickiness, and hair styling properties. The hair styling compositions of Examples 24 and 25 were superior in the evaluation of wash-off compared to the hair styling composition of Example 20 (not containing a nonionic surfactant) shown in Table 9 (Examples 24 and 25 were rated as "○" for wash-off. Criteria: Example 20).

[0117] [Table 12]

[0118] From the results shown in Table 12, the hair styling composition of Example 26 was superior in the evaluation of wash-off, stickiness, and hair styling properties compared to the hair styling compositions of Examples 27 to 29. Therefore, it can be understood that the inclusion of polyoxyethylene glyceryl triisostearate (20E.O.), among other nonionic surfactants, results in superior evaluation of wash-off, stickiness, and hair styling properties. The hair styling compositions of Examples 27 to 29 were superior in the evaluation of wash-off compared to the hair styling composition of Example 20 shown in Table 9 (which did not contain a nonionic surfactant) (Examples 27 to 29 were evaluated as "○" for wash-off. Criteria: Example 20).

[0119] (Polarizing microscope observation) The hair styling compositions prepared in Examples 5 to 7, Examples 15 to 19, Comparative Example 10, and Comparative Examples 13 to 16, and the newly prepared Example 30 (prepared by mixing 4% by mass of sunflower seed wax and 96% by mass of liquid paraffin using a known method for producing a hair styling composition) were observed using a polarizing microscope. For the polarizing microscope observation, about 0.5 to 1.5 mg of each hair styling composition of Examples 5 to 7, Examples 15 to 19, Example 30, Comparative Example 10, and Comparative Example 13 to 16 was applied to each slide glass, thinly spread, and then a cover glass was placed on each slide glass. The composition was observed at room temperature with polarized light at a magnification of 400 times using a polarizing microscope (Olympus Corporation: BX51). The observed image of each hair styling composition was also photographed. The photographs of the microscopic observation images of the hair styling compositions of Examples 5 to 7, Examples 15 to 19, Example 30, Comparative Example 10, and Comparative Example 13 to 16 are shown in Figures 1 to 3. The total length of the bar at the bottom right of each photograph shown in Figures 1 to 3 is 5.0 μm.

[0120] (Microscopic observation results: Figure 1) From the results shown in FIG. 1, the hair styling compositions of Example 30 and Examples 5 to 7 were observed to have linear crystalline objects. In addition, the linear crystalline objects tended to be longer and thicker in the order of Examples 30, 5, 6, and 7 (the blending amount of sunflower seed wax was 4, 5, 10, and 20% by mass, respectively), and the distribution state of the linear crystalline objects tended to be denser (the amount of linear crystalline objects increased). Therefore, it can be said that the linear crystalline objects become longer, thicker, and more densely distributed as the blending amount of sunflower seed wax increases. It is suggested that the viscosity of the hair styling composition tends to be higher as the linear crystalline objects become longer, thicker, and more densely distributed.

[0121] (Microscopic observation results: Figure 2) From the results shown in FIG. 2, the hair styling compositions of Examples 15 to 19 were observed to have linear crystalline objects. The distribution of linear crystalline objects tended to become denser (the amount of linear crystalline objects increased) in the order of Examples 15 to 19 (3, 4, 5, 10, and 20 mass% of rice bran wax with an iodine value of 3.0 or less). Therefore, it can be said that the linear crystalline objects became longer, thicker, and more densely distributed as the amount of rice bran wax with an iodine value of 3.0 or less increased. It is suggested that the viscosity of the hair styling composition tends to increase as the linear crystalline objects become longer, thicker, and more densely distributed.

[0122] (Microscopic observation results: Figure 3) From the results shown in FIG. 3, observation images of linear crystalline objects were obtained in Example 5 containing the component (A1) and Example 17 containing the component (A2), but no observation images of linear crystalline objects were obtained in any of the hair styling compositions of Comparative Examples 10 and 13 to 16 containing solid oils other than the components (A1) and (A2). In addition, the hair styling compositions of Comparative Example 10 (containing rice bran wax with an iodine value of 5.4), Comparative Example 13 (containing carnauba wax), and Comparative Example 14 (containing candelilla wax) gave observation images of spherical crystalline objects, but no crystalline objects were observed in the hair styling compositions of Comparative Example 15 (containing beeswax) and Comparative Example 16 (containing microcrystalline wax). Therefore, it is considered that the shape of the crystalline objects differs depending on the type of solid oil (component (A1), component (A2), and other solid oils), and therefore the property of improving the viscosity of the hair styling composition may also differ. In addition, a comparison of Example 17 (containing rice bran wax with an iodine value of 1.0) and Comparative Example 10 (containing rice bran wax with an iodine value of 5.4) showed that the state of the crystalline matter differed depending on the iodine value of the rice bran wax. This difference in the state of the crystalline matter may be due to the difference in the amount of unsaturated groups in the rice bran wax.
