2. Description of the Related Art Conventionally, aerosol-type foamy oxidative hair dye compositions that are discharged in the form of foam using a propellant such as LPG are known. The aerosol-type oxidative hair dye composition is stored in an aerosol container together with a propellant using this as a stock solution.
The aerosol-type foamy oxidative hair dye composition is composed of a one-component type that uses an alkali agent and utilizes oxidation by air, a first agent that contains an alkaline agent, and a second agent that contains an oxidant. There are multiple drug formulas such as two drug formulas. When discharged by the force of the propellant, the propellant expands to form bubbles.

  The above-mentioned patent document 1 is an aerosol foam hair dye / bleaching agent that has an amphoteric polymer, a specific alkali component, and lanolin as essential components, suppresses an irritating odor, and has good hair feel after hair dyeing or decoloring treatment. It is a composition.

  However, there is room for improvement regarding the stability, viscosity stability, and leveling property of the emulsion, which is a different viewpoint. Particularly in the first agent, the demand for these improvements was strong. In the aerosol foam hair dye composition, the stability of the emulsion during storage is important. In particular, it is important to improve the stability of the emulsion in order to take advantage of the fact that it can be used in a plurality of times.

  As a general story, a multi-component oxidative hair dye composition uses the action of an alkali agent and an oxidizer, so a first agent that contains an alkali agent and a second agent that contains an oxidizer are good. It is important to be able to mix. Mixability is also important for aerosol foam oxidative hair dye compositions.

  For example, in the low viscosity range of 2000 mPa · s or less, the stability of the viscosity is often superior to the second agent containing the oxidizing agent. The 1st agent which mix | blends an alkaline agent may contain many components which are the form of a salt from 2nd agent, and it existed in the tendency for the maintenance of a stable viscosity to become difficult in a low viscosity range. If the first agent can no longer maintain the initial viscosity, the difference from the viscosity of the second agent will increase and the mixing property will decrease.

  When the first agent blended with the alkaline agent is an emulsion, if the viscosity of the first agent is low, emulsification cannot be maintained and the water-soluble component and oil-based component may be separated. It was. The same is true for a one-component aerosol foam hair dye composition, but the emulsification cannot be maintained, and if separated, the contents may not be discharged uniformly.

  As a result of intensive studies, the inventor of the present application has found that the stability, viscosity stability, and leveling of the emulsion can be improved by further adding a cationic polymer in addition to the amphoteric polymer.

  Therefore, it is an object to be solved to provide an aerosol foamed hair dye composition that is excellent in emulsion stability, viscosity stability, and leveling property.

  The aerosol foamed hair dye composition disclosed in the present application described above is excellent in stability, viscosity stability, and leveling property of the emulsion because it contains a cationic polymer in addition to the amphoteric polymer.

  The inventors of the present application speculate that the addition of a cationic polymer in addition to the amphoteric polymer forms a complex, and the complex contributes to the above effect.

(Emulsion stability test)
Test method: The stock solution for the first agent in each example was stored in a constant temperature bath at 60 ° C.
Evaluation method: It was confirmed by visual inspection whether or not the emulsion was separated, and the number of days required until the emulsion was separated.

  Evaluation criteria: “5” if the number of days until separation is 1 week or more, “4” if it is 3 days or more and less than 1 week, or “4” if it is 1 day or more and less than 3 days Was evaluated as “2” when it was 12 hours or more and less than 1 day, and “1” when it was less than 12 hours.

  The above test is an accelerated test. Therefore, if the result of the acceleration test is good, it is reasonably estimated that a good effect can be obtained even when the first agent filled with the propellant is stored in the aerosol container at room temperature.

(Viscosity stability test)
Test method: The stock solution for the first agent of each example was prepared and stored in a thermostatic layer at 50 ° C. for 1 month.

Measurement was performed under conditions of 12 rpm, 25 ° C., and 1 minute. The “viscosity” column in the table describes the measurement results immediately after preparation.
Evaluation method: The viscosity ratio (viscosity ratio = viscosity after storage for 1 month / viscosity immediately after preparation) was calculated from the viscosity of the stock solution for first agent immediately after preparation and the viscosity of the stock solution for first agent after storage for 1 month. The viscosity ratio closer to 1 indicates that the viscosity stability during storage is more excellent.

  Evaluation criteria: “5” when the viscosity ratio is 0.80 or more and less than 1.20, and when the viscosity ratio is 0.60 or more and less than 0.80 or 1.2 or more and less than 2.0 "4", when the viscosity ratio is 0.40 or more and less than 0.60 or 2.0 or more and less than 3.0, "3", the viscosity ratio is 0.20 or more and less than 0.40 or 3.0 or more When it was less than 4.0, it was evaluated as “2”, and when the viscosity ratio was less than 0.20 or 4.0 or more, it was evaluated as “1”.

  The above test is an accelerated test. Therefore, if the result of the acceleration test is good, it is reasonably estimated that a good effect can be obtained even when the first agent filled with the propellant is stored in the aerosol container at room temperature.

(Uniformity test)
A total of 10 g of each of the compositions of Examples 1 to 38 and Comparative Examples 1 to 4 was discharged from the aerosol container, and 3 g of a white hair bundle of white hair (hereinafter simply referred to as “hair bundle”) of 30 cm in length from the tip. Combing was performed 10 times in the distal direction by hand, and the hair bundle was left in a thermostatic 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. The degree of color unevenness of the hair bundle was observed visually by 10 panelists, and it was evaluated (sensory evaluation) whether or not leveling was good. Specifically, “5” indicates “stained without unevenness”, “4” indicates “stained almost without unevenness”, “3” indicates “stained with too much unevenness”, “highly unevenness” "2", and "1" is "very uneven". 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.

(Foamability test)
3 g of each composition of Examples 1-38 and Comparative Examples 1-4 was discharged on the flat board from the said aerosol container on 25 degreeC conditions. Immediately after this discharge, 10 panelists evaluated the bulkiness (foaming property) of the bubbles visually (sensory evaluation).
Examples 1 to 38 exhibited good foaming power. In Example 7, many panelists evaluated as “bulky” compared to other Examples, and exhibited more excellent foaming properties.
