  As can be seen from the compositions of the various compositions described above, even if the alcohols have the same carbon number, the effects of different properties are confirmed by the combined use of other components. That is, from the disclosure of the carbon number of alcohol, the effect exhibited by the combined use of other components could not be predicted.

  For example, in order to improve the hair dyeing performance of the hair cosmetic composition, a method of increasing the amount of higher alcohol can be employed, but there is a risk that the viscosity will increase too much, maintaining the appropriate viscosity and dyeing the hair. Sexual compatibility was difficult. Further, in the first agent containing an alkaline agent of a multi-component hair cosmetic composition, in order to improve the viscosity stability of the first agent, the type of higher alcohol is changed, the amount of surfactant is reduced. The stability of the agent that is an emulsion may be deteriorated (separation may occur). What is the stability of the appropriate viscosity of the first agent and the stability of the agent that is an emulsion? It was difficult to achieve both.

  Therefore, it is an object to be solved by the present invention to provide a hair cosmetic composition that maintains the stability of an agent that is an emulsion and the stability of the viscosity of a specific range of the agent. In addition, it is an object of the present invention to provide a hair cosmetic composition having good hair dyeing power and lightness. It is another object of the present invention to provide a first agent of a multi-component hair cosmetic composition that exhibits these effects.

That is, the 1st agent of the multi-component hair cosmetic composition which has these effects was also completed. In addition, since the hair cosmetic composition can be of a single agent type, a hair cosmetic composition having the above effects was also completed.

It is a usage method of the hair cosmetic composition which discharges the hair cosmetic composition in any one of 1st invention-4th invention using compressed gas or liquefied gas.

(First invention)
According to the first invention, it is possible to obtain both effects of stability of the agent which is an emulsion and a small viscosity change in a specific viscosity region. Since a higher amount of C22 or higher alcohol is used in a relatively large amount, compared to other higher alcohols, there is an effect of superior emulsification stability at a high temperature when blended in the same amount and less change in viscosity. Since it is excellent in viscosity stability and emulsion stability, the hair cosmetic composition can be stored for a long period of time. Moreover, the hair cosmetic composition is excellent in lightness imparting effect and hair dyeing power. As a result of extensive research, the inventor of the present application blended a large amount of C22 or higher alcohol into the hair cosmetic composition by satisfying the above conditions (a) to (c), and the preferable effect of the present invention was obtained.

  In hair cosmetic compositions, it is possible to adopt a technique for increasing the viscosity in order to improve the stability of the agent which is an emulsion, but there is a risk of causing operability problems, and the discharge amount per unit time is not constant. There is a fear. Moreover, although the method of increasing the compounding quantity of a higher alcohol in order to improve the hair dyeing property of hair cosmetics composition can be considered, there exists a possibility that a viscosity may become larger than necessary also in this case.

  Although it is possible to adopt a technique of changing the type of higher alcohol to reduce the amount of surfactant in order to achieve stability of the viscosity, the stability of the agent as an emulsion may be lowered. Thereby, control of discharge amount may become difficult, there exists a possibility that an agent cannot be discharged uniformly, and there exists a possibility that the operativity of hair cosmetics composition may fall.

  The third invention of the present application is an agent which is a good viscosity stability and emulsion of a hair cosmetic composition when the hair cosmetic composition has a viscosity suitable for ejection using a compressed gas or a liquefied gas. Stability can be obtained. Moreover, the hair cosmetic composition is excellent in lightness imparting effect and hair dyeing power.

Preferably, the 1st agent of the multi-component hair cosmetic composition discharged with compressed gas or liquefied gas is provided.

  For example, as described in Examples below, when the first agent does not contain a dye such as an oxidation dye, it is excellent in emulsification stability, viscosity stability, and brightness.

(Fifth invention)
According to the fifth aspect of the present invention, a multi-component hair cosmetic composition comprising a first agent excellent in emulsification stability, viscosity stability, and hair coloring power / lightness provision is provided. Preferably, a multi-component hair cosmetic composition that is discharged with compressed gas or liquefied gas is provided.

The said mass ratio is 0.50-1, Preferably it is 0.55-1, More preferably, it is 0.60-1. When the mass ratio of the higher alcohol of C22 or lower is less than 0.50, there is a possibility that compatibility between the stability of the agent and the viscosity stability cannot be achieved.

[Preparation of two-component hair cosmetic composition]
The 1st agent which is the emulsion which concerns on Examples 1-12 and Comparative Examples 1-4 of Table 1 shown later was prepared by the conventional method. Since Examples 1 and 2 do not contain an oxidative dye, the “hair dyeing power” was not evaluated.

  The 2nd agent used with the 1st agent which concerns on said Examples 1-12 and Comparative Examples 1-4 was set as the composition shown in Table 2.

〔test〕
(Stability test of the first agent)
Test method: The 1st agent composition of each case was preserve | saved in the 60 degreeC thermostat.

  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, “3” if it is 1 day or more and less than 3 days “2” when it was 12 hours or more and less than 1 day, and “1” when it was less than 12 hours.

(Viscosity stability test of the first agent)
Test Method: The first agent composition of each example was stored in a constant temperature layer at 40 ° C. for 6 months. The viscosity of the composition after storage for 6 months was measured using a B-type viscometer with a rotor No. 3. Measurement was performed under the conditions of 12 rpm, 25 ° C. and 1 minute.

  Evaluation method: The viscosity ratio (viscosity ratio = viscosity after storage for 6 months / viscosity immediately after preparation) was calculated from the viscosity of the composition immediately after preparation measured under the same conditions and the viscosity of the composition after storage for 6 months. 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”.
<Hair dyeing strength test and lightness test>
A hair dye obtained by mixing the first agent and the second agent at a mass ratio of 1: 1 was applied to a black human hair bundle (hereinafter simply referred to as a hair bundle) using a brush, and the room temperature ( (25 ° C.) for 30 minutes. Next, after the hair dye adhering to the hair bundle was washed away with water, the hair bundle was subjected to shampooing twice and rinsing once. Subsequently, the hair bundle was dried with warm air to obtain a hair bundle that was dyed. With respect to the hair bundle subjected to the hair dyeing treatment, the hair dyeing power and the lightness were evaluated according to the methods shown below.
