Summary of the Invention

Problems to be Solved by the Invention

[0005] Since the non-aqueous hair composition shown in Patent Document 1 has a relatively low water content, it can impart a texture different from that of aqueous compositions to hair. Non-aqueous hair compositions usually impart textures such as hair coherence and manageability because they have a relatively high content of oily components.

[0006] On the other hand, hair is known to be damaged by physical treatments such as brushing, using a hand dryer, or a hot iron, or chemical treatments such as oxidative hair dyeing or permanent waving. Damaged hair tends to have a lower hair bounce compared to before being damaged.

[0007] Various techniques have been proposed to give hair firmness and body. However, there are currently relatively few proposals for techniques that can give hair firmness and body using non-aqueous hair compositions.

[0008] In view of the above circumstances, the object of the present invention is to provide a non-aqueous hair composition that can impart firmness and body to hair, and a hair treatment method using the non-aqueous hair composition. [Means for solving the problem]

[0009] As a result of diligent research by the inventors, it was found that a non-aqueous hair composition containing a specific oil, ferulic acid, a polyphenol having one or more 3,4-dihydroxyphenyl groups, a polyphenol having one or more 3,4,5-trihydroxyphenyl groups, and a polyphenol having two or more 4-hydroxyphenyl groups can improve the firmness and elasticity of hair. Based on this finding, the inventors completed the present invention.

Further, according to the hair treatment method of the present invention, a hair treatment method using the non-aqueous hair composition of the present invention can be provided. [Modes for Carrying Out the Invention]

[0020] Based on an embodiment of the present invention (hereinafter referred to as "the present embodiment"), the present invention will be described below.

[0021] [Non-aqueous hair composition] The non-aqueous hair composition of the present embodiment includes the non-aqueous hair composition of the first embodiment shown below and the non-aqueous hair composition of the second embodiment.

[0022] The non-aqueous hair composition of the first embodiment (hereinafter referred to as "the composition of the first embodiment") is a non-aqueous hair composition comprising one or more selected from vegetable oils with an iodine value of 90 to 170, esters having unsaturated bonds (excluding vegetable oils with an iodine value of 90 to 170), unsaturated higher alcohols, and unsaturated fatty acids, and one or more selected from ferulic acid, polyphenols having one or more 3,4-dihydroxyphenyl groups, polyphenols having one or more 3,4,5-trihydroxyphenyl groups, and polyphenols having two or more 4-hydroxyphenyl groups. According to the composition of the first embodiment, hair can be given firmness and body. "Firmness and body" refers to the elastic feel of the hair when touched by hand (the same meaning will be used in the following description).

[0023] The second embodiment of the non-aqueous hair composition (hereinafter referred to as "the composition of the second embodiment") is a non-aqueous hair composition that contains one or more selected from safflower oil, sesame oil, rice bran oil, esters having unsaturated bonds (except safflower oil, sesame oil, and rice bran oil), unsaturated higher alcohols, and unsaturated fatty acids, as well as one or more selected from ferulic acid, polyphenols having one or more 3,4-dihydroxyphenyl groups, polyphenols having one or more 3,4,5-trihydroxyphenyl groups, and polyphenols having two or more 4-hydroxyphenyl groups. According to the composition of the second embodiment, hair can be given firmness and body.

[0024] In the following description, vegetable oils with an iodine value of 90 or more and 170 or less, esters having unsaturated bonds (excluding vegetable oils with an iodine value of 90 or more and 170 or less), unsaturated higher alcohols, and unsaturated fatty acids may be collectively referred to as "specific vegetable oils, etc.". Further, in the second embodiment, safflower oil, sesame oil, rice bran oil, esters having unsaturated bonds (excluding safflower oil, sesame oil, and rice bran oil), unsaturated higher alcohols, and unsaturated fatty acids may be collectively referred to as "specific safflower oil, etc.". Further, in the first and second embodiments, ferulic acid, polyphenols having one or two or more 3,4-dihydroxyphenyl groups, polyphenols having one or two or more 3,4,5-trihydroxyphenyl groups, and polyphenols having two or more 4-hydroxyphenyl groups may be collectively referred to as "ferulic acid, etc.".

[0025] Although the details of the mechanism by which the non-aqueous hair composition of this embodiment can impart stiffness to hair are unclear, ferulic acid, etc. formulated in the composition of the first embodiment or the composition of the second embodiment are known to undergo a radical coupling reaction with components having an unsaturated double bond (-CH=CH-) by taking a quinone structure to produce a product (Literatures 1 and 2 below). And the specific vegetable oils, etc. or specific safflower oil, etc. formulated in the composition of the first embodiment or the composition of the second embodiment have an unsaturated double bond (-CH=CH-) in their chemical structure, and a product is produced by a radical coupling reaction with ferulic acid, etc., and the phenolic hydroxyl group of the product is linked to the amino group (NH2-) or thiol group (SH-) of the hair, so the connection of "the product of specific vegetable oils, etc. or specific safflower oil, etc. and ferulic acid, etc." - "hair" is realized, and it is considered possible that it contributes to imparting stiffness to the hair. Further, the connection of "the product of specific vegetable oils, etc. or specific safflower oil, etc. and ferulic acid, etc." - "hair" may contribute not only to the stiffness of the hair but also to the smoothness of the hair.

[0118] As for the hair treatment method of this embodiment, other than using the composition of the first embodiment or the composition of the second embodiment, any known hair treatment method may be used. Therefore, the method of using the composition of the first embodiment or the composition of the second embodiment described above may also be used. [Examples]

[0119] The present invention will be described in detail below based on examples, but the present invention should not be interpreted as being limited based on the description of these examples.

[0120] (Preparation of non-aqueous hair compositions of Examples 1-13 and Comparative Examples 1-12) Using the ingredients listed below, the non-aqueous hair compositions of Examples 1-13 and Comparative Examples 1-12 were prepared by mixing the ingredients by conventional methods to obtain the compositions shown in Tables 1-9. The non-aqueous hair compositions of Examples 1-13 and Comparative Examples 1-12 were in liquid form at 25°C. The values ​​in the ingredient column of Tables 1-9 are in mass%, and "-" indicates that the ingredient was not included.

[0121] (Ingredients used) • Specific vegetable oils, etc. or specific safflower oils, etc. Safflower oil (iodine value 142.0), sesame oil (iodine value 110.2), rice bran oil (iodine value 102.7), oleyl oleate, oleyl alcohol, oleic acid • Ferulic acid, etc. Ferulic acid, chlorogenic acid, gallic acid Other ingredients Squalane, Caprylic / Capric Triglyceride, Olive Oil (Iodine Value 81.3), Linseed Oil (Iodine Value 177.0), Rosehip Oil (Iodine Value 177.5), Ethanol

[0122] (Measurement of iodine value) The iodine values ​​of the safflower oil, sesame oil, rice bran oil, olive oil, linseed oil, and rosehip oil used were measured according to the iodine value measurement method specified in the 2021 Quasi-Drug Raw Material Standards, using the measurement method described below.

[0123] Depending on the iodine value of the sample to be measured, the sample amount (iodine value 50-100: 0.4-0.2g, iodine value 100-150: 0.2-0.12g, iodine value 150-200: 0.15-0.10g) was precisely weighed into a glass container and placed in a 500mL iodine bottle. 10mL of cyclohexane was added to dissolve the iodine. Next, 25mL of iodine monochloride solution was added, the bottle was stoppered, and the mixture was gently shaken. The mixture was left to stand in the dark at 20-30°C, with occasional shaking, for a reaction time depending on the iodine value of the sample (iodine value 50-100: 30 minutes, iodine value 100-200: 60 minutes). Then, 20mL of potassium iodide solution (1 mol / L) and 100mL of water were added and shaken, and the liberated iodine was titrated with 0.1 mol / L sodium thiosulfate solution. The iodine value was calculated using the following formula (1). A blank test was performed using the same method to determine the blank value.

[0124] Iodine value = (ab) × 1.269 / c (1)

[0125] In equation (1) above, a, b, and c are as follows: a: Amount of 0.1 mol / L sodium thiosulfate solution consumed for the blank test (mL) b: Amount of 0.1 mol / L sodium thiosulfate solution consumed by the sample (mL) c: Sample amount (g)

[0126] (Rating 1) The firmness and resilience of hair were evaluated using the non-aqueous hair compositions of Examples 1-13 and Comparative Examples 1-12, as shown below.

[0127] (Evaluation of Example 1 and Comparative Examples 1-3) Using hair that had been previously treated with oxidative hair dye, collected from the same Japanese woman, multiple hair bundles (each bundle consisting of human hair approximately 30 cm in length, weighing approximately 4 g) were created. The following treatments (1) to (4) were performed on the created hair bundles.

[0128] (1) The hair strands were washed with a 13.5% by mass sodium polyoxyethylene lauryl ether sulfate aqueous solution and rinsed with water for 30 seconds. After rinsing, the wet hair strands were dried with warm air from a hairdryer and left at room temperature for 30 minutes. (2) To the hair bundles obtained in the treatment described in (1), 0.08 g of any of the non-aqueous hair compositions from Example 1 or Comparative Examples 1-3 was applied and left at room temperature for 30 minutes to obtain each treated hair bundle. Untreated hair bundles were also prepared in which nothing was applied. (3) Each treated hair bundle and the untreated hair bundle were immersed in a beaker containing 40g of 1% by mass sodium dodecyl sulfate aqueous solution for about 1 second, and then each hair bundle was removed from the beaker. This immersion and removal procedure was repeated a total of 5 times, and then each hair bundle was rinsed with water for 30 seconds. (4) After drying each wet strand of hair with a hairdryer on a warm setting, leave it at room temperature for 30 minutes.

[0129] Using each hair bundle that underwent the above treatments (1) to (4), evaluators were asked to indicate whether the "hair firmness and resilience" was superior or inferior compared to a reference hair bundle. Here, the evaluation of "hair firmness and resilience" was performed by holding the root portion of the hair bundle with the fingers of one hand and the tip portion with the fingers of the other hand, and bending the middle portion of the hair bundle (the portion between the root and tip) at a 45° angle. If the hair bundle felt more elastic than the reference hair bundle, it was evaluated as having superior "hair firmness and resilience," and if no elasticity was felt, it was evaluated as having inferior "hair firmness and resilience." The evaluators were 10 people who regularly evaluate hair. The evaluation results were then obtained based on the evaluation criteria shown below. Note that the evaluation using the untreated hair bundle in treatment (2) above is referred to as Reference Example 1.

[0130] (Evaluation Criteria) ○: Seven or more people responded that the hair had superior firmness and body compared to the standard hair bundle. Equivalent: Four to six respondents reported that the hair had superior firmness and resilience compared to the standard hair bundle. ×: Three or fewer respondents reported that the hair had superior firmness and resilience compared to the standard hair sample.

[0131] In the evaluation of Example 1 and Comparative Examples 1-3, the reference hair bundle was the hair bundle treated with the non-aqueous hair composition of Comparative Example 1.

[0132] (Results of Evaluation 1: Example 1, Comparative Examples 1-3, Reference Example 1) Table 1 shows the evaluation results for Example 1, Comparative Examples 1-3, and Reference Example 1.

[0133] [Table 1]

[0134] As shown in Table 1, the non-aqueous hair composition of Example 1, which contained safflower oil (a specific vegetable oil, etc. or a specific safflower oil, etc.) with an iodine value of 142.0 and ferulic acid (ferulic acid, etc.), performed better in evaluating hair firmness and elasticity than the non-aqueous hair compositions of Comparative Examples 1 to 3, which did not contain either or both of the safflower oil or ferulic acid. The non-aqueous hair composition of Comparative Example 1 contained tri(caprylic / capric acid) glyceryl (an ester without unsaturated bonds (all alkyl chains are saturated)), but did not contain the specific vegetable oil, etc. or the specific safflower oil, etc., and therefore performed poorly in evaluating hair firmness and elasticity. From these results, it can be seen that using a vegetable oil (safflower oil) with an iodine value of 90 to 170 as an ingredient to combine with ferulic acid, etc., in a non-aqueous hair composition can impart firmness and elasticity to the hair.

[0135] (Evaluation of Examples 2-3, Comparative Examples 1, 4-11) Using the non-aqueous hair compositions of Examples 2-3 and Comparative Examples 1-4-11 prepared as described above, hair treatment was performed in the same manner as the evaluation of Examples 1 and Comparative Examples 1-3 described above, and the firmness and elasticity of the hair were evaluated (Reference Example 1 was not performed). Tables 2-6 show the evaluation results of the non-aqueous hair compositions of Examples 2-3 and Comparative Examples 1-4-11.

[0136] (Results of Evaluation 1: Example 2, Comparative Examples 1 and 4) Table 2 shows the evaluation results for the non-aqueous hair compositions of Example 2 and Comparative Examples 1 and 4. In the evaluation of Example 2 and Comparative Examples 1 and 4, the evaluation criteria used were hair bundles treated with the non-aqueous hair composition of Comparative Example 1 and hair bundles treated with the non-aqueous hair composition of Comparative Example 4, respectively.

[0137] [Table 2]

[0138] As shown in Table 2, the non-aqueous hair composition of Example 2, which contained sesame oil (specific vegetable oils, etc. or specific safflower oil, etc.) with an iodine value of 110.2 and ferulic acid (ferulic acid, etc.), was superior in evaluating hair firmness and elasticity compared to the non-aqueous hair compositions of Comparative Examples 1 and 4, which did not contain either the sesame oil or ferulic acid.

[0139] (Results of Evaluation 1: Example 3, Comparative Examples 1 and 5) Table 3 shows the evaluation results of the non-aqueous hair compositions of Example 3 and Comparative Examples 1 and 5.

[0140] [Table 3]

[0141] As shown in Table 3, the non-aqueous hair composition of Example 3, which contained rice bran oil (specific vegetable oils, etc. or specific safflower oil, etc.) with an iodine value of 102.7 and ferulic acid (ferulic acid, etc.), was superior in evaluating hair firmness and elasticity compared to the non-aqueous hair compositions of Comparative Examples 1 and 5, which did not contain either rice bran oil or ferulic acid.

[0142] (Results of Evaluation 1: Comparative Examples 1, 6-7) Table 4 shows the evaluation results for Comparative Examples 1, 6-7, and 6.7. In the evaluation of Comparative Examples 1, 6-7, the evaluation criteria used were hair bundles treated with the non-aqueous hair composition of Comparative Example 1 and hair bundles treated with the non-aqueous hair composition of Comparative Example 7, respectively.

[0143] [Table 4]

[0144] As shown in Table 4, the non-aqueous hair composition of Comparative Example 6, which contained olive oil with an iodine value of 81.3 (not falling under any of the categories of specific vegetable oils or specific safflower oils) and ferulic acid, performed better in evaluating hair firmness and elasticity than the non-aqueous hair composition of Comparative Example 1, which did not contain the olive oil. However, the non-aqueous hair composition of Comparative Example 6 performed similarly in evaluating hair firmness and elasticity to the non-aqueous hair composition of Comparative Example 6, which did not contain ferulic acid.

[0145] (Results of Evaluation 1: Comparative Example 1, 8-9) Table 5 shows the evaluation results for Comparative Examples 1 and 8-9, which are non-aqueous hair compositions. In the evaluation of Comparative Examples 1 and 8-9, the evaluation criteria used were hair bundles treated with the non-aqueous hair composition of Comparative Example 1 and hair bundles treated with the non-aqueous hair composition of Comparative Example 9, respectively.

[0146] [Table 5]

[0147] As shown in Table 5, the non-aqueous hair composition of Comparative Example 8, which contained linseed oil with an iodine value of 177.0 (not falling under any of the categories of specific vegetable oils or specific safflower oils) and ferulic acid, performed better in evaluating hair firmness and elasticity than the non-aqueous hair composition of Comparative Example 1, which did not contain the linseed oil. However, the non-aqueous hair composition of Comparative Example 8 performed worse in evaluating hair firmness and elasticity than the non-aqueous hair composition of Comparative Example 9, which did not contain ferulic acid.

[0148] (Results of Evaluation 1: Comparative Example 1, 10-11) Table 6 shows the evaluation results for Comparative Examples 1 and 10-11, which are non-aqueous hair compositions. In the evaluation of Comparative Examples 1 and 10-11, the evaluation criteria used were hair bundles treated with the non-aqueous hair composition of Comparative Example 1 and hair bundles treated with the non-aqueous hair composition of Comparative Example 11, respectively.

[0149] [Table 6]

[0150] As shown in Table 6, the non-aqueous hair composition of Comparative Example 10, which contained rosehip oil with an iodine value of 177.5 (not falling under any of the categories of specific vegetable oils or specific safflower oils) and ferulic acid, performed better in evaluating hair firmness and elasticity than the non-aqueous hair composition of Comparative Example 1, which did not contain the rosehip oil. However, the non-aqueous hair composition of Comparative Example 10 performed similarly in evaluating hair firmness and elasticity to the non-aqueous hair composition of Comparative Example 11, which did not contain ferulic acid.

[0151] The results shown in Tables 1 to 6 indicate that non-aqueous hair compositions (Examples 1 to 3) containing a specific vegetable oil or specific safflower oil with an iodine value of 90 to 170, and ferulic acid, etc., are superior in evaluating hair firmness and resilience compared to non-aqueous hair compositions (Comparative Examples 1 to 11) that do not contain either or both of the specific vegetable oil or specific safflower oil with an iodine value of 90 to 170, ferulic acid, etc. Therefore, it can be seen that in non-aqueous hair compositions, the inclusion of a specific vegetable oil or specific safflower oil with an iodine value of 90 to 170, along with ferulic acid, etc., can impart firmness and resilience to the hair.

[0152] (Evaluation of Examples 1, 4-13, and Comparative Examples 1 and 12) For the evaluation of Examples 1, 4-13 and Comparative Examples 1 and 12, the hair's firmness and resilience were evaluated by making the following changes from the hair treatment described above in the evaluations of Example 1 and Comparative Examples 1-3. • In the process of (2), replace the non-aqueous hair composition applied to the hair bundle with one of the non-aqueous hair compositions from Examples 1, 4-13, Comparative Examples 1, and 12. • Perform steps (1) through (4) consecutively a total of three times. • Example 1 has not been implemented.

[0153] Tables 7 to 9 show the evaluation results of the non-aqueous hair compositions of Examples 1, 4 to 13 and Comparative Examples 1 and 12.

[0154] (Results of Evaluation 1: Examples 1, 4-7, Comparative Example 1) Table 7 shows the evaluation results for the non-aqueous hair compositions of Examples 1, 4-7, and Comparative Example 1. In the evaluation of Examples 1, 4-7, and Comparative Example 1, the hair bundles treated in Comparative Example 1 were used as the evaluation standard.

[0155] [Table 7]

[0156] As shown in Table 7, the non-aqueous hair compositions of Examples 1, 4-7, which contained 0.5-80% by mass of safflower oil (specific vegetable oil, etc. or specific safflower oil, etc.) with an iodine value of 142.0 and ferulic acid, were superior in evaluating hair firmness and elasticity compared to the non-aqueous hair composition of Comparative Example 1, which did not contain the safflower oil.

[0157] (Results of Evaluation 1: Examples 8-10, Comparative Example 1) Table 8 shows the evaluation results for the non-aqueous hair compositions of Examples 8-10 and Comparative Example 1. In the evaluation of Examples 8-10 and Comparative Example 1, the hair bundles treated in Comparative Example 1 were used as the evaluation standard.

[0158] [Table 8]

[0159] As shown in Table 8, the non-aqueous hair compositions of Examples 8-10, which contained oleyl oleate, oleyl alcohol, or oleic acid (specific vegetable oils, etc., or specific safflower oils, etc.) and ferulic acid, were superior in evaluating hair firmness and elasticity compared to the non-aqueous hair composition of Comparative Example 1, which did not contain specific vegetable oils, etc., or specific safflower oils, etc. The non-aqueous hair composition of Comparative Example 1 contained tri(caprylic / capric acid) glyceryl (an ester without unsaturated bonds (all alkyl chains are saturated)), but because it did not contain specific vegetable oils, etc., or specific safflower oils, etc., it was inferior in evaluating hair firmness and elasticity. These results show that in non-aqueous hair compositions, using esters with unsaturated bonds (excluding vegetable oils with an iodine value of 90 to 170) (oleyl oleate), unsaturated higher alcohols (oleyl oleate), or unsaturated fatty acids (oleic acid), which are specific vegetable oils or specific safflower oils, as ingredients to be combined with ferulic acid, etc., can impart firmness and body to the hair.

[0160] (Results of Evaluation 1: Examples 11-13, Comparative Example 12) Table 9 shows the evaluation results for the non-aqueous hair compositions of Examples 11-13 and Comparative Example 12. In the evaluation of Examples 11-13 and Comparative Example 12, the hair bundles treated with Comparative Example 12 were used as the evaluation standard.

[0161] [Table 9]

[0162] As shown in Table 9, the non-aqueous hair compositions of Examples 11-13, which contained safflower oil with an iodine value of 142.0 (specific vegetable oil, etc. or specific safflower oil, etc.) and ferulic acid, chlorogenic acid, or gallic acid (ferulic acid, etc.), were superior in evaluating hair firmness and resilience compared to the non-aqueous hair composition of Comparative Example 12, which did not contain ferulic acid, etc. From these results, it can be seen that using ferulic acid, a polyphenol having one 3,4-dihydroxyphenyl group (chlorogenic acid), or a polyphenol having one 3,4,5-trihydroxyphenyl group (gallic acid) as an ingredient to be combined with specific vegetable oil, etc. or specific safflower oil, etc. in a non-aqueous hair composition can impart firmness and resilience to the hair.

[0163] (Rating 2) The coefficient of dynamic friction of hair using the non-aqueous hair compositions of Examples 1-7 and 11-13 prepared as described above was evaluated as follows.

[0164] Using the non-aqueous hair compositions of Examples 1-7 and 11-13, a hair treatment was performed with the following modifications from the hair treatment evaluated in Example 1 and Comparative Examples 1-3 described above. • In the process of (2), replace the non-aqueous hair composition applied to the hair bundle with one of the non-aqueous hair compositions from Examples 1-7 or 11-13. • Perform steps (1) through (4) consecutively a total of 10 times. • Example 1 has not been implemented.

[0165] The coefficient of dynamic friction was measured for each hair bundle treated with the non-aqueous hair compositions of Examples 1-7 and 11-13.

[0166] (Measurement of the coefficient of kinetic friction) Measurement device: Kato Tech Co., Ltd. friction feel tester "KES-SE" was used. Sample preparation: From each hair bundle treated with the non-aqueous hair compositions of Examples 1-7 and 11-13, 11 strands of hair were selected and fixed on a microscope slide at 1 mm intervals, with the hairs approximately 30 mm long aligned from root to tip and parallel to each other. Number of measurements: 5 times each Measurement speed: 1mm / sec Measurement conditions: The measurement sample was fixed on a friction tester, and an arm-shaped jig with a silicone rubber contact was set up, with a 50g weight attached. In this state, the jig was slid from the root to the tip of the hair, and the coefficient of dynamic friction obtained from a 20mm range in the middle part of the hair was recorded. The measurement procedure was performed in a constant temperature and humidity chamber (25°C, relative humidity 50%). Here, a lower value for the coefficient of dynamic friction indicates better hair sliding.

[0167] Note that the measurement results for the non-aqueous hair compositions of Examples 1-3 shown in Table 10, the measurement results for the non-aqueous hair compositions of Examples 4-7 shown in Table 11, and the measurement results for the non-aqueous hair compositions of Examples 11-13 were measured using hair bundles from different lots (the hair lots in each table are the same). Therefore, while the values ​​of the dynamic friction coefficients allow for comparison of each example within the same table, it is not possible to compare each example using the values ​​of the dynamic friction coefficients between different tables.

[0168] (Results of Evaluation 2: Examples 1-3) Table 10 shows the measurement results of the dynamic friction coefficient of hair in the non-aqueous hair compositions of Examples 1 to 3.

[0169] [Table 10]

[0170] As shown in Table 10, the non-aqueous hair compositions of Examples 1 and 2, which contained safflower oil with an iodine value of 142.0 and sesame oil with an iodine value of 110.2 as specific vegetable oils or specific safflower oils, had lower dynamic friction coefficients compared to the non-aqueous hair composition of Example 3, which contained rice bran oil with an iodine value of 102.7. From these results, it can be seen that using vegetable oils with a relatively high iodine value as specific vegetable oils or specific safflower oils tends to result in a lower dynamic friction coefficient and improved hair glide.

[0171] (Results of Evaluation 2: Examples 4-7) Table 11 shows the measurement results of the dynamic friction coefficient of hair in the non-aqueous hair compositions of Examples 4 to 7.

[0172] [Table 11]

[0173] As shown in Table 11, the non-aqueous hair compositions of Examples 5-7, which contained 3% by mass or more of a specific vegetable oil or safflower oil with an iodine value of 142.0, had a lower coefficient of dynamic friction compared to the non-aqueous hair composition of Example 4, which contained 0.5% by mass of the safflower oil. Furthermore, the non-aqueous hair composition of Example 7, which contained 80% by mass of a specific vegetable oil or safflower oil with an iodine value of 142.0, had a lower coefficient of dynamic friction compared to the non-aqueous hair compositions of Examples 5 and 6, which contained 3% by mass or 30% by mass of the safflower oil. From these results, it can be seen that when the amount of a specific vegetable oil or safflower oil added to a non-aqueous hair composition is relatively high, the coefficient of dynamic friction tends to decrease, resulting in superior hair slipperiness.

[0174] (Results of Evaluation 2: Examples 11-13) Table 12 shows the measurement results of the dynamic friction coefficient of hair in the non-aqueous hair compositions of Examples 11 to 13.

[0175] [Table 12]

[0176] As shown in Table 12, the non-aqueous hair compositions of Examples 11-12, which contained ferulic acid and chlorogenic acid, had lower dynamic friction coefficients compared to the non-aqueous hair composition of Example 13, which contained gallic acid.
