[0001] The present invention relates to a hair quality composition that imparts firmness and stiffness to hair, makes it easier to create volume in the hair when styling, and can preferably maintain the styled state of the hair. 感を出しやすくするとともに、毛髪をスタイリングした状態を好適に維持することができる毛質用組成物に関する。

Background Art

[0002] People with thin and supple hair, or those whose hair has become thin or the number of hairs has decreased with aging, have difficulty styling their hair into the desired hairstyle, so the development of styling assistance methods is desired. So far, various film-forming resins for hair styling have been developed and proposed in order to make styling easier by attaching a film-forming substance to the surface of the hair and increasing hair rigidity. However, these film-forming resins for hair styling not only significantly deteriorate the texture of the hair surface and lose the flexibility of the hair, but also lose film rigidity in a high-humidity situation and the styled hairstyle collapses, or the styling is easily disrupted when using a comb or the like, and such problems could not be solved.

[0003] また、毛髪自体のハリやコシを向上させる技術としては、毛髪の内部に亜鉛化合物を浸透させる方法(特許文献1)が提案されている。しかし、皮膜性樹脂を含まないスタイリング組成物に亜鉛化合物を配合した場合、毛髪への浸透量が十分に得られないという課題があった。

[0035] The present invention will be described in detail below based on examples, but the present invention is not limited to these examples.

[0036] The samples for Reference Example 1, Example 1, and Comparative Examples 1-3 were prepared by conventional methods using the formulations shown in Table 1. In Table 1, the numbers to the right of each component represent the content (mass%) of each component, and the formulations were adjusted to total 100% by mass.

[0037] Details of each component listed in Table 1 are as follows: For solid silica, commercially available solid silica was used. The average particle diameter of the primary particles was 40 nm, and the average particle diameter of the secondary particles was 7.4 μm. Multiple primary particles aggregated to form secondary particles, and pores were present between the multiple primary particles. For hollow silica, commercially available hollow silica was used. The average particle diameter was 3.7 μm. The outer shell had multiple pores. In each example and comparative example, the mass ratio of solid silica to hollow silica was solid silica / hollow silica = 1 / 8. For glyceryl glucoside, commercially available glyceryl glucoside was used. A mixture of 1-α-glyceryl glucoside, 1-β-glyceryl glucoside, 2-α-glyceryl glucoside, and 2-β-glyceryl glucoside was used. For the arginine derivative, commercially available dihydroxypropylarginine hydrochloride was used. For the sorbitol-polypropylene glycol ether, commercially available sorbitol-polypropylene glycol ether was used. The average number of moles of propylene oxide added was 10.

[0038] [Zinc permeability evaluation] The amount of zinc penetrating the hair was evaluated using a non-destructive elemental analysis X-ray fluorescence analyzer. This analytical method allows us to obtain the characteristic X-ray intensity of the zinc component contained in the hair. Since this characteristic X-ray intensity is proportional to the concentration of the element, the amount of zinc in the samples can be compared relatively by comparing the intensities. First, commercially available black human hair was prepared. This black human hair was bundled at the roots, with a length of 15 cm and a weight of 2 g per bundle. The black human hair samples were pre-washed with a 10% sodium lauryl sulfate (also known as SLS) solution. After drying, five strands of hair were cut from the sample, 0.1 g of zinc was applied to each strand, and the entire hair was spread evenly with fingers. Next, the hair bundles were washed by immersing them in 100 ml of 1% SLS solution for 5 seconds, 100 ml of deionized water for 5 seconds, and another 100 ml of deionized water for 5 seconds. After that, they were dried for 30 minutes in a constant temperature forced-air dryer (manufactured by Tokyo Rika Kiki Co., Ltd.: EYELA WINDY OVEN WFO-600SD) set to 57°C. These steps were repeated a total of 10 times to obtain the measurement samples. The amount of zinc in the measurement samples was measured using the above apparatus, and Table 1 shows the rate of change in the amount of zinc, with Reference Example 1 set to 100%.

[0039] [Set-based evaluation] The setting ability was evaluated using a combing tester (model SK-7A) manufactured by Techno Hashimoto Co., Ltd. First, commercially available black human hair specifically for the combing tester was prepared. This black human hair was trimmed at the roots, 30 cm long, and weighed 250 g per bundle. A known adhesive was applied to a range of approximately 3 cm from the roots of one bundle of black human hair. The area where the adhesive was applied was sandwiched and fixed between two plates to create a test sample. The black human hair of the test sample was pre-washed with a 10% sodium lauryl sulfate (also known as SLS) solution. After further drying, it was set in the combing tester. A program was executed to comb the hair 10 times, and the load during combing was measured. Here, since there may be variability in the data for the first few measurements out of the 10, the results of the 6th to 10th measurements were used. The load during the 5 combing cycles was accumulated and used as the initial value of the accumulated load. Next, 1 g of the hair styling composition from each example or comparative example was applied to the black human hair whose initial load accumulation value had been measured. Furthermore, the hair styling composition was spread evenly throughout the hair. This black human hair was then placed in the combing tester described above, and a program was executed in which the hair was combed 10 times, and the load during combing was measured. The load during the 6th to 10th combing cycles (5 cycles) was accumulated to obtain the measured value of the load accumulation.

[0040] The percentage change in the cumulative load value before and after application of the hair styling product composition was calculated using the following formula. The results are shown in Table 1. Percentage change of cumulative load value (%) = (Measured value / Initial value) × 100

[0041] [Table 1]

[0042] As shown in Table 1, in Comparative Examples 1 to 3, in which glyceryl glucoside, arginine derivative, and sorbitol polypropylene glycol ether were individually formulated, the cumulative load value of the hair increased from the initial value and improved setting properties. However, in Example 1, which incorporated all three components, the decrease in zinc intake was surprisingly suppressed, and the setting properties were also very good.

[0043] Table 2 shows examples of formulations for the hair composition of the present invention. Unless otherwise specified, the amounts of each formulation are in mass %.
