In the emulsified hair styling composition containing the component (A), the oil droplets in the oil in water (O / W) disintegrate and the component (A) adheres to the hair, thereby hardening the hair bundle and making the hair curly. Hair styling power, hair styling power to form hair bundles, and hair styling holding power are exhibited. However, the component (A) is difficult to emulsify, and granular insoluble matter is generated in the emulsified hair styling agent composition, or the emulsified hair styling agent composition becomes non-uniform, and the emulsifying characteristics tend to deteriorate. In the conventional emulsifying hair conditioner composition containing the component (A), a higher fatty acid salt excellent in emulsification of the component (A) has been generally used as an emulsifier, but when the higher fatty acid salt is used as an emulsifier, it is emulsified. There is a problem that the wash-off property of the hair-conditioning agent composition at the time of washing the hair tends to be lowered, and the stability of the compounding component is lowered by becoming alkaline.

On the other hand, in the emulsified hair styling composition of the present invention, since the component (C1) and / or the component (C2) is used as an essential emulsifier component, the wash-off property at the time of washing the hair is lowered. The emulsifying property of the component (A) can be enhanced without causing a problem. The component (C1) and the component (C2) have a long-chain linear alkyl group.

Further, since the component (C1) and the component (C2) are ionic surfactants, the dispersibility of the emulsified particles is enhanced by the electrostatic repulsion of the emulsified particles, so that the emulsifying characteristics can be further enhanced. ..

The hair was towel-dried and then dried with a hair dryer. The dried hair was touched by hand, and the washability was evaluated according to the following evaluation criteria.

<Evaluation criteria for washability>
〇 (Good): There is no stiffness in the hair after washing and drying, and there is no residual feeling of the hair styling agent composition.
X (defective): The hair is stiff after washing and drying, and there is a residual feeling of the hair styling agent composition.

(Test Example 4: Spreading on hair during hair styling)
Due to the good operability (that is, whether or not it can be operated during hair styling) from the start of hair styling to the end of hair styling (that is, whether or not it can be operated during hair styling) when hair styling is performed in Test Example 2, the hair is stretched during hair styling. evaluated.

As a result, in the emulsified hair styling agent compositions obtained in Examples 1, 2, 6, 8 to 12, 13, 16 to 19, 21 to 27 and Comparative Examples 1 and 2, the fingers are caught until the hair styling is completed. There was no resistance, hair styling was possible with good operability, and good growth was shown. Above all, the emulsified hair styling agent compositions obtained in Examples 19, 21 to 24 were extremely excellent in spreading on the hair during hair styling. Further, in the emulsified hair styling agent compositions obtained in Examples 3 to 5, 7, 14, 15 and 20, although a feeling of resistance such as a finger being caught occurs in the latter half of the hair styling, an operation that is practically acceptable during the hair styling. It maintained its sexuality and was practically acceptable. On the other hand, in the emulsified hair styling composition obtained in Example 28, before the hair styling was completed, the resistance feeling that a finger was caught became strong, and it became difficult to styling the hair (unsuitable for hair styling that arranges for a long time). However, it can be used for short-time hair styling).

The compositions and results are shown in Tables 1-10 below.
