In conventional multi-color decoloring agents or oxidative hair dyes, the viscosity of a 1st agent and / or a 2nd agent may be high, and the mixing property of a 1st agent and a 2nd agent may be inferior. When the viscosity of the first agent and / or the second agent is lowered in order to improve the mixing property between the first agent and the second agent, the viscosity of the resulting mixture is also lowered, and as a result, the adhesion to the hair is lowered. The mixture becomes liable to fall off from the hair. When the viscosity of the mixed agent is low, in particular, the adhesion to the short hair part (for example, the cut-out part) is lowered, and the fall is more likely to occur. When the adhesiveness to hair falls, decolorization and hair dye fall.

In the hair dye or the bleaching agent of the said patent document 1, the 1st agent and a 2nd agent can be mixed to some extent favorable, and the adhesiveness to the hair of the obtained mixture agent can be improved. However, in the hair dye or the bleach described in Patent Document 1, the first agent needs to contain a nonionic surfactant in a specific amount, and the second agent needs to include a polyoxyethylene polyoxypropylene alkyl ether in a specific amount.

In addition, Patent Literature 2 does not describe at all whether the mixing property is improved or the adhesion to hair is improved by using an amideamine compound.

In the oxidation hair dye described in the patent document 3, since a cationic surfactant is used, finger combing of hair can be made favorable. However, Patent Document 3 does not describe the use of tertiary amine type cationic surfactants as cationic surfactants at all, and only quaternary amine type cationic surfactants are used in Examples. Moreover, in patent document 3, in order to improve the stability of an oxidizing dye, it is described that it is preferable that a cationic surfactant is contained in a 1st agent.

Preparation of the first and second agents:

The compounding component shown in following Tables 1-4 was mix | blended (mixing unit is the mass%), and the 1st agent and the 2nd agent were prepared. The compounding quantity (the compounding quantity in 1st 100 mass% and the compounding quantity in 2nd 100 mass%) in a table | surface was shown by the compounding quantity (unit: mass%) of pure components except 28% ammonia water. In addition, 28% ammonia water in the table | surface was shown not with the compounding quantity of ammonia, but with the compounding quantity of 28% ammonia water.

Preparation of Blends:

In the combination of the first agent and the second agent shown in Tables 1 to 4 below, the obtained second agent is mixed in 1 g with respect to the obtained first 1 g, and the first agent and the second agent are used using a dedicated brush. The mixture was stirred until it was thoroughly mixed to obtain a mixture.

(evaluation)

The following evaluation was performed about the obtained 1st agent, 2nd agent, and a mixture agent. Evaluation results were shown in Tables 1-4.

Test Example 1: pH

The pH of the obtained 1st agent, 2nd agent, and a mixed agent was measured using the pH meter ("F-74" by Horiba Seisakusho Co., Ltd.).

Test Example 2: Viscosity

The viscosity at 25 degrees C of the obtained 1st agent, the 2nd agent, and the mixing agent was measured. In addition, from the viscosity at 25 ℃ the measured first claim η _1, the second the viscosity η of the 25 ℃ of viscosity η _2, of the mixture according to 25 ℃ _three, non-A ((1 + X) × η ₃ / was determined a value of _{{(1 × η 1) +} (X × η 2)}). In addition, in Examples 1-16 and Comparative Examples 1-4 which mix 2nd agent with 1g with respect to 1st 1g, X is 1.

In addition, the viscosity was measured on condition of rotation speed 12 rpm and rotation time 1 minute using the No. 4 rotor using TV-25 type viscometer (made by Toki Sangyo Co., Ltd.).

(Test Example 3: Mixed)

The obtained 1st 15g and the obtained 2nd 15g were mixed, and it stirred for 30 second using the exclusive brush. Three expert panels observed visually the mixing state after stirring, and negotiated and determined the evaluation result.

<Evaluation standard of mixture>

○ ○ (quite good): There is no uneven part and it is mixed completely.

○ (good): almost no uneven portion, almost completely mixed

△ (slightly good): some uneven parts remain

× (defect): many uneven parts remain

Test Example 4: Adhesion to Hair

5 g of the obtained mixture was applied to a flat 10 cm long hair bundle (manufactured by Beaulux Co., Ltd.) horizontally using a dedicated brush, and the hair bundle was vertically observed for 3 minutes. The adhesion to hair was determined based on the following criteria.

<Evaluation standard of adhesion to hair>

○ ○ (quite good): 3 minutes after application, the admixture does not drip from the hair and there is no movement on the hair

○ (good): After 3 minutes of application, the admixture is moving downward on the hair to less than 2 cm.

△ (slightly good): 1 minute after application, the mixture moves below 2 cm or more and less than 10 cm on the hair, and the mixture does not fall off from the hair for 3 minutes after application.

× (poor): The mixture drips off the hair for 3 minutes after application

(Test Example 5: Conditioning property)

20 g of the obtained admixture was uniformly applied to hair having a flat hair bundle of 10 g using an exclusive brush. After leaving for 12 minutes after coating, water washing was performed. Conditioning property at the time of water washing was determined based on the following criteria. Three expert panels consulted to determine the evaluation results.

<Evaluation criteria of conditioning property>

○○ (quite good): I do not feel stiffness

○ (good): feel a little stiffness

△ (slightly good): feel a little stiffness

× (poor): I feel stiffness strongly
