  The material and internal pressure of the aerosol container can be appropriately determined in accordance with the types of alkali agent, oxidizing agent, propellant, and the method for containing each agent.

  As described above, the present application also discloses an aerosol foamed hair dye composition, and a product including a propellant and an aerosol container.

  Examples will be described below. The technical scope of the aerosol type foamy hair dye composition disclosed in the present application is not limited to the following examples.

<Preparation of aerosol type foam hair dye composition>
Examples 1 to 39
By blending the components shown in Tables 1 to 4, the first solution stock solution and the second agent stock solution of Examples 1 to 39 were prepared. In addition, the unit of the numerical value which shows the compounding quantity of Tables 1-4 is the mass%. In addition, the “remaining amount” of purified water in the examples means the remaining amount when each of the first agent stock solution and the second agent stock solution in each example is 100% by mass.

  Furthermore, the first agent stock solution and the second agent stock solution of each Example were filled into an aerosol container equipped with a simultaneous mixing and discharging mechanism, and each was filled with a propellant (LPG) at the ratios shown in Tables 1 to 4. The 1st agent and the 2nd agent of each Example were prepared.

  The 1st agent and 2nd agent of each Example were discharged from this aerosol container, and the aerosol type foamy oxidation hair dye composition of Examples 1-39 was obtained.

[Comparative Examples 1-4]
Moreover, the stock solution for 1st agents and the stock solution for 2nd agents of Comparative Examples 1-4 were prepared by mix | blending each component shown by Table 5. FIG. In addition, the unit of the numerical value which shows the compounding quantity of Table 5 is the mass%. In addition, the “remaining amount” of purified water in the comparative examples means the remaining amount when the first agent stock solution and the second agent stock solution in each comparative example are each 100 mass%.

  Further, each of the first agent stock solution and the second agent stock solution of each comparative example was filled into an aerosol container equipped with a simultaneous mixing and discharging mechanism, and each was filled with a propellant (LPG) at a ratio shown in Table 5, The 1st agent and 2nd agent of the comparative example were prepared.

  The first agent and the second agent of each comparative example were discharged from this aerosol container, and the aerosol-type foamy oxidative hair dye compositions of Comparative Examples 1 to 4 were obtained.

<Hair dyeing>
Each composition of Examples 1 to 39 and Comparative Examples 1 to 4 was discharged from the aerosol container in an amount of 1.5 g and applied to 1 g of a white hair bundle (hereinafter simply referred to as “hair bundle”) by hand. Then, the hair bundle was left in a constant temperature bath (30 ° C.) for 30 minutes. Next, the composition adhering to the hair bundle was washed with water, and then the hair bundle was treated once with shampoo and rinse (conditioner). Subsequently, the hair bundle was dried with warm air. In this way, the hair bundle was subjected to a hair dyeing treatment using the composition.

<Evaluation 1: Foam quality>
A “sticky feeling” can be recognized by touching the bubbles with the hand or looking at the bubbles. For the convenience of quantification, the following test evaluated the tight feeling.
3g of each composition of Examples 1-39 and Comparative Examples 1-4 was discharged from the said aerosol container on the flat board on 25 degreeC conditions. Immediately after this discharge, the first and second agents were mixed by hand, and after one minute of tilting the 45 ° plate as it was, 10 panelists visually evaluated the degree of foam falling (feeling of foam tightness) (sensory evaluation) )did. The evaluation criteria are “5” for movement, “4” for movement, “3” for movement, “2” for movement, very movement. The larger one was rated as “1” and was rated on a 5-point scale. The average score of the evaluations of the 10 panelists for each evaluation target thus obtained was calculated, and when there was a numerical value below the decimal point, the evaluation was determined by rounding off. The evaluation results are shown in Tables 1-5.

<Evaluation 2: Hair dyeing power>
A panelist observed the hair bundle after the hair dyeing process using each composition of Examples 1-39 and Comparative Examples 1-4 visually, and evaluated hair dyeing power (sensory evaluation). Specifically, "5" indicates that the hair coloring power is excellent, "4" indicates that the hair coloring power is somewhat superior, and 3 indicates that the hair coloring power is normal. ”,“ Slightly inferior hair dyeing ”is“ 2 ”, and“ Inferior hair dyeing ”is“ 1 ”. The average score of the evaluation of 10 panelists for each evaluation target was calculated, and when there was a numerical value below the decimal point, the evaluation was determined by rounding off. The evaluation results are shown in Tables 1-5.

<Evaluation 3: Foaming property>
3g of each composition of Examples 1-39 and Comparative Examples 1-4 was discharged from the said aerosol container on the flat board on 25 degreeC conditions. Immediately after this discharge, 10 panelists evaluated the bulkiness (foaming property) of the bubbles visually (sensory evaluation).
Examples 1-39 exhibited good foaming power. In Examples 5, 9, 22, 24, 25, and 26, many panelists evaluated as “bulky” as compared with other examples, and exhibited more excellent foaming properties.

  The table description method will be explained. The brackets on the right side of the higher alcohol indicate the carbon number of the higher alcohol. The brackets following the POE of the nonionic surfactant and the anionic surfactant indicate the number of polymerization of POE. “Hydrogen peroxide (35%)” represents 35% hydrogen peroxide solution. Monoethanolamine solution, ammonia water, and hydrogen peroxide water are% (w / w). The agent whose “form of the stock solution” is an emulsion is an emulsion even after filling with a propellant. The ratio of stock solution to propellant is a mass ratio. “C16 ↑ / C14 ↓” means a mass ratio of a higher alcohol of 16 or more and a higher alcohol of C14 or less. “SAA / OH” means the mass ratio of surfactant to higher alcohol.
