[0016] [Figure 1] 1 is a perspective view of a hair-washing cosmetic storage product according to an embodiment. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] A hair washing cosmetic storage product 100 according to an embodiment of the present invention will be described below with reference to Fig. 1. However, the technical scope of the present invention is not limited to the illustrated example. Note that a hair washing cosmetic storage product is a product in which a hair washing cosmetic is stored in a container. Moreover, the hair washing cosmetic composition broadly includes products such as shampoo that are applied to human hair when washing the hair. In addition, in this specification, a numerical range described using "to" is intended to include the numerical values ​​before and after it as the lower limit and upper limit.

[0018] [Configuration of one embodiment] As shown in FIG. 1, a hair wash cosmetic storage product 100 has a hair wash cosmetic 1 stored in a storage container 2.

[0019] [(1) Hair washing cosmetics] The hair washing cosmetic composition 1 contains an emollient, an anionic surfactant, an amphoteric surfactant, a nonionic surfactant, and a cationic polymer.

[0020] [a Emollient] Hair washing cosmetic preparation 1 contains PPG-5-laureth-5 and PPG1-PEG-9 lauryl glycol ether as emollients for moisturizing hair and improving the smoothness of the hair.

[0021] PPG-5-Laureth-5 is the addition polymerization of ethylene oxide and propylene oxide to lauryl alcohol. The content of PPG-5-laureth-5 in the hair washing cosmetic preparation 1 is preferably 0.025% by mass to 0.100% by mass, and from the viewpoint of obtaining sufficient effects while suppressing costs, it is particularly preferably 0.050% by mass.

[0022] PPG1-PEG-9 lauryl glycol ether is a reaction product of lauryl epoxide and glycol with the addition of ethylene oxide and propylene oxide, with the average mole numbers of addition being 9 and 1, respectively. The content of PPG1-PEG-9 lauryl glycol ether in the hair washing cosmetic preparation 1 is preferably 0.025% by mass to 0.100% by mass, and from the viewpoint of obtaining sufficient effects while suppressing costs, it is particularly preferably 0.050% by mass.

[0023] [b Anionic surfactant] Hair washing cosmetic preparation 1 contains sodium C14-16-α-olefin sulfonate and disodium cocoyl glutamate as anionic surfactants.

[0024] Sodium C14-16-α-olefin sulfonate (Na olefin (C14-16) sulfonate) is a compound with carbon atoms of 14-16 (C 14-16 ) is a mixture of sodium salts of alkylsulfonic acids in which α-olefins are sulfonated.

[0025] Disodium cocoyl glutamate is the disodium salt of cocoyl glutamic acid.

[0026] [c Amplex surfactant] Hair washing cosmetic composition 1 contains cocamidopropyl betaine as a double-active surfactant.

[0027] Cocamidopropyl betaine is an amphoteric compound (inner salt) obtained by carboxymethylating coconut oil fatty acid amidopropyl dimethylamine.

[0028] [d Nonionic surfactants] Hair washing cosmetic preparation 1 contains laureth-2 as a nonionic surfactant.

[0029] Laureth-2 is the polyethylene glycol ether of lauryl alcohol.

[0030] [e Cationic polymer] The hair washing cosmetic preparation 1 contains polyoctanium-10 and polyoctanium-47 as cationic polymers.

[0031] Polyoctanium-10 is a polymer of quaternary ammonium salt obtained by adding glycidyltrimethylammonium chloride to hydroxyethyl cellulose.

[0032] Polyquaternium-47 is a polyquaternary ammonium chloride obtained by polymerizing acrylic acid, methyl acrylate, and methacrylamide propyl trimethyl ammonium chloride.

[0033] [(2) Storage container] The storage container 2 is a container in which the hair washing cosmetic 1 is stored, and is preferably a pump-type container that ejects the hair washing cosmetic 1 by pressing the top as shown in FIG. 1, but is not particularly limited as long as it is capable of storing the hair washing cosmetic 1.

[0034] [Effects of the Second Embodiment] According to the hair washing cosmetic storage product 100 of this embodiment, the hair washing cosmetic 1 contains PPG-5-laureth-5 and PPG1-PEG-9 lauryl glycol ether.

[0035] PPG-5-Laureth-5 has a high effect of imparting high lubricity to hair and improving the ease of running fingers through hair after washing, but since it is poorly soluble in water, it is prone to separation in the hair washing cosmetic composition 1. If PPG-5-Laureth-5 separates in the hair washing cosmetic composition 1, it may cause a decrease in the performance of the hair washing cosmetic composition 1 in terms of cleaning ability, foaming, transparency, etc.

[0036] In this regard, since PPG1-PEG-9 lauryl glycol ether is an emollient agent having a structure similar to that of PPG-5-laureth-5 and is easily soluble in water, the inclusion of PPG1-PEG-9 lauryl glycol ether at the same time makes it easier to dissolve PPG-5-laureth-5 in water. This makes it possible to obtain the effect of PPG-5-Laureth-5 in improving the smoothness of hair while reducing the risk of the PPG-5-Laureth-5 not dissolving in water and thus reducing the performance of the hair washing cosmetic composition 1.

[0037] Therefore, by containing PPG-5-laureth-5 and PPG1-PEG-9 lauryl glycol ether, the hair washing cosmetic composition 1 can easily improve the ease of running fingers through hair after washing, even in the case where the hair washing cosmetic composition does not contain silicone.

[0038] In addition, PPG-5-Laureth-5 contributes to improving the smoothness of hair run through, particularly after washing, and PPG1-PEG-9 Lauryl Glycol Ether contributes to improving the smoothness of hair run through, particularly during washing. Therefore, by containing both of these ingredients, it becomes easier to improve the smoothness of hair run through not only after washing but also during washing.

[0039] In addition, by containing 0.025% by mass or more and 0.100% by mass or less of PPG-5-Laureth-5, it is possible to prevent increased costs and the risk of PPG-5-Laureth-5 remaining undissolved due to excessive use of PPG-5-Laureth-5, while making it easier to fully achieve the effect of improving the smoothness of hair after washing.

[0040] Furthermore, by containing 0.025% by mass or more and 0.100% by mass or less of PPG1-PEG-9 lauryl glycol ether, it is possible to prevent an increase in cost due to excessive use of PPG1-PEG-9 lauryl glycol ether, while making it easier to fully obtain the effects of making PPG-5-laureth-5 more soluble in water and improving the ease of running fingers through hair during washing.

[0041] In addition, in addition to PPG-5-laureth-5 and PPG1-PEG-9 lauryl glycol ether, the hair washing cosmetic composition 1 contains sodium C14-16-α-olefin sulfonate and disodium cocoyl glutamate as anionic surfactants, cocamidopropyl betaine as an amphoteric surfactant, laureth-2 as a nonionic surfactant, and polyoctanium-10 and polyoctanium-47 as cationic polymers, thereby achieving good performance as a shampoo, such as high hair cleansing properties. EXAMPLES

[0050] [2 Sample Preparation] Using the hair washing cosmetics according to the above examples and comparative examples, hair samples were prepared in the following manner.

[0051] [(1) Sample 1] Step 1: Prepare black human hair manufactured by Beaulax (with the roots aligned, at least 17 cm long, and 3 to 5 cm wide). Step 2: Human black hair was adhered to an acrylic plate measuring 5 cm wide x 3 cm long x 2 mm thick (Sumipex E, manufactured by Sumika Acrylic Sales Co., Ltd.) The roots of human black hair (20 cm long, 4 g) were adhered to the acrylic plate using an acrylic adhesive (SUPERX HYPER Wide, manufactured by Cemedine Co., Ltd.). Step 3: Wet the hair with water. Step 4: 1.8 g of a 20% aqueous solution of sodium laureth sulfate was placed on one hand, and the hand was moved back and forth 20 times in a direction perpendicular to the flow of the hair to wash the hair. Step 5: Rinse with 30 degree water for 1 minute. Step 6: Steps 4 and 5 above were carried out three times. Step 7: 1.8 g of the hair washing cosmetic composition according to Example 1 was placed on one hand, and the hand was moved back and forth 20 times in a direction perpendicular to the flow of the hair to wash the hair. Step 8: Rinse with 30 degree water for 1 minute. Step 9: Air dry using cool air until completely dry. Step 10: Comb the hair five times with a comb (SAMZO anti-static cut comb) until the hair was free of tangles.

[0052] [(2) Sample 2] Example 2 was used in step 7. Except for this point, the procedure is the same as sample 1.

[0053] [(3) Sample 3] Example 3 was used in step 7. Except for this point, the procedure is the same as sample 1.

[0054] [(4) Sample 4] Comparative Example 1 was used in Procedure 7. Except for this point, the sample was the same as Sample 1.

[0055] [(5) Sample 5] Comparative Example 2 was used in Procedure 7. Except for this point, the procedure is the same as Sample 1.

[0056] [(6) Sample 6] Comparative Example 3 was used in Procedure 7. Except for this point, the procedure is the same as Sample 1.

[0057] [3 Exam Content] Using the above samples, the following two types of tests were carried out.

[0058] [(1) Test 1] A sensory evaluation of the feel of the brush running its fingers through each of the above samples was carried out as follows.

[0059] That is, the evaluators combed each of the hair samples 1 to 6 with their fingers and then rated them as A if the hair felt very smooth, B if the hair felt smooth, C if the hair felt difficult to run through, and D if the hair felt very difficult to run through. Ten judges (judges 1 to 10) each performed an evaluation and then calculated the total score of the 10 judges as follows: A: 2 points, B: 1 point, C: 0.5 points, D: 0 points.

[0060] [(2) Test 2] The resistance value of each of the above samples was measured when combing with a comb as follows.

[0061] That is, a combing test was carried out using a multipurpose hair tester (manufactured by DiaStron, model number: fibra.one) and the resistance value was measured. Specifically, the test was carried out twice, with the average resistance value calculated from three runs, and the average of the two tests was used to evaluate combing. A lower resistance value indicates better combing and superiority.

[0062] [4 Test Results] The results of Test 1 are shown in Table I, and the results of Test 2 are shown in Table II.

[0063] [Table 1]

[0064] [Table 2]

[0065] [5 Ratings] First, in terms of the results of Test 1, comparing the test results for Samples 1 to 3, which were cleaned using Examples 1 to 3, with the test results for Samples 4 to 6, which were cleaned using Comparative Examples 1 to 3, all evaluators rated Samples 1 to 3 as B or higher, with a total score of 10 or 15 points, whereas some evaluators rated Samples 4 to 6 as C or D, with a total score of 5, 8, or 6.5 points. From this point of view, it can be seen that by incorporating both PPG-5-laureth-5 and PPG1-PEG-9 lauryl glycol ether into a hair washing cosmetic composition, the ease with which hair can be run through after washing with the hair washing cosmetic composition can be improved.

[0066] In addition, from the results of Test 2, when comparing the test results for Samples 1 to 3 washed using Examples 1 to 3 with the test results for Samples 4 to 6 washed using Comparative Examples 1 to 3, the overall average resistance values ​​when combing for Samples 1 to 3 were 16.01 mJ, 13.60 mJ, and 14.72 mJ, whereas the overall average resistance values ​​when combing for Samples 4 to 6 were 16.59 mJ, 20.79 mJ, and 16.54 mJ. From this point of view, it can be seen that by incorporating both PPG-5-laureth-5 and PPG1-PEG-9 lauryl glycol ether in a hair washing cosmetic composition, the resistance when combing hair after washing with the hair washing cosmetic composition can be reduced, improving the ease of running your fingers through the hair.
