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

[0017] A hair wash 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. A hair wash cosmetic storage product is a product in which hair wash cosmetics are stored in a container. Furthermore, 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 stated using "to" includes the numerical values ​​stated before and after it as the lower limit and upper limit.

[0018] [Configuration of 1 embodiment] As shown in FIG. 1, the 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 its smoothness.

[0021] PPG-5-Laureth-5 is an addition polymerization of lauryl alcohol with ethylene oxide and propylene oxide. 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 keeping costs down, 0.050% by mass is particularly preferable.

[0022] PPG1-PEG-9 lauryl glycol ether is a reaction product of lauryl epoxide and glycol to which ethylene oxide and propylene oxide are added, with the average number of moles added 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 keeping costs down, 0.050% by mass is particularly preferable.

[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 14-16 carbon atoms (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. Ambidextrous surfactant] Hair washing cosmetic composition 1 contains cocamidopropyl betaine as an amphoteric 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] Polyoctanium-47 is a polyquaternary ammonium chloride obtained by polymerizing acrylic acid, methyl acrylate, and methacrylamidopropyltrimethylammonium 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 Figure 1, but is not particularly limited as long as it can store the hair washing cosmetic 1.

[0034] [2 Effects of the embodiment] According to the hair wash cosmetic storage product 100 of this embodiment, the hair wash 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 luster to hair and improving the ease of running fingers through hair after washing, but because 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 cleansing ability, foaming, transparency, etc.

[0036] In this regard, 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, so by simultaneously incorporating PPG1-PEG-9 lauryl glycol ether, PPG-5-laureth-5 becomes more easily soluble 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 it not dissolving in water and reducing the performance of the hair washing cosmetic 1.

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

[0038] Furthermore, PPG-5-laureth-5 contributes to improving the smoothness of hair runnability, particularly after washing, and PPG1-PEG-9 lauryl glycol ether contributes to improving the smoothness of hair runnability, particularly during washing. Therefore, by including both of these ingredients, it becomes easier to improve the smoothness of hair runnability not only after washing but also during washing.

[0039] Furthermore, by containing 0.025% by mass or more and 0.100% by mass or less of PPG-5-laureth-5, it becomes easier to fully achieve the effect of improving the ease of running fingers through hair after washing, while preventing increased costs and the risk of PPG-5-laureth-5 remaining undissolved due to excessive use of PPG-5-laureth-5.

[0040] Furthermore, by including 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 costs 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 shampooing.

[0041] In addition, in addition to PPG-5-laureth-5 and PPG1-PEG-9 lauryl glycol ether, 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. [Example]

[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 (roots aligned, 17 cm or more in length, 3 to 5 cm in width) manufactured by Beaulax. Step 2: Human black hair was adhered to an acrylic plate (Sumipex E, manufactured by Sumika Acrylic Sales Co., Ltd.) measuring 5 cm wide x 3 cm long x 2 mm thick. The roots of the 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 direction of the hair flow to wash the hair. Step 5: Rinse with 30 degree water for 1 minute. Step 6: Steps 4 and 5 were performed three times. Procedure 7: 1.8 g of the hair washing cosmetic composition according to Example 1 was placed on one hand, and the hand was then moved back and forth 20 times in a direction perpendicular to the direction of the hair flow to wash the hair. Step 8: Rinse with 30 degree water for 1 minute. Step 9: Air dry with cold air until completely dry. Step 10: Comb through the hair five times with a comb (SAMZO anti-static cutting comb) until the hair was free of tangles.

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

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

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

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

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

[0057] [3 Exam Contents] The following two types of tests were carried out using the above samples.

[0058] [(1) Test 1] A sensory evaluation of the smoothness of the fingers was carried out for each of the above samples 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 was very smooth to the touch, B if the hair was easy to run through, C if the hair was difficult to run through, and D if the hair was very difficult to run through. Ten judges (judges 1 to 10) each conducted an evaluation, and then the total score of the 10 judges was calculated 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 conducted 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, from the results of Test 1, comparing the test results for Samples 1 to 3 cleaned using Examples 1 to 3 with the test results for Samples 4 to 6 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 including both PPG-5-laureth-5 and PPG1-PEG-9 lauryl glycol ether in a hair washing cosmetic, the ease with which hair can be run through after washing with the hair washing cosmetic can be improved.

[0066] Furthermore, 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, or 14.72 mJ, whereas the overall average resistance values ​​when combing for Samples 4 to 6 were 16.59 mJ, 20.79 mJ, or 16.54 mJ. From this point of view, it can be seen that by including both PPG-5-laureth-5 and PPG1-PEG-9 lauryl glycol ether in a hair washing cosmetic, the resistance when combing hair after washing with the hair washing cosmetic can be reduced, improving the ease of running your fingers through the hair.
