Component (A) functions as a main hair styling component. Component (A) improves the hair setting ability at the time of hair setting. Moreover, an ingredient (A) makes hair setting maintenance high.

When a cationic film-forming polymer is used without using the component (A), the component (B) does not disperse well and tends to aggregate, so an aerosol spray hairdressing agent composition having excellent stability It is difficult to get

When the nonionic film-forming polymer is used without using the component (A), 1) the hair setting ability at hair setting is improved, 2) the hair holding power is increased, and 3) the hair repositioning property is increased, And 4) It is inferior to any performance of making a hair a natural finish with a mat, and it is difficult to exhibit all these effects.

(Examples 1 to 7 and Comparative Examples 1 to 12)
The formulation components shown in Tables 1 to 3 below were blended (blending unit is% by mass) to prepare an aerosol spray hair styling composition (undiluted solution) having the composition shown in Tables 1 to 3 below. The obtained aerosol spray hair styling composition (stock solution) was filled into an aerosol spray container (volume 95 mL). Then, after the aerosol valve was clinched into an aerosol spray container, the propellant shown in Tables 1 to 3 below was filled from the stem, and a button suitable for the stem was attached to produce an aerosol spray hair styling agent.

(Evaluation)
Five expert panels performed the following evaluations.

(Test Example 1: Compatibility)
Each of the obtained stock solutions (aerosol spray hair styling composition) and each propellant is added to a pressure bottle (“Aerosol Test Bottle” manufactured by Tokyo High Polymer Co., Ltd., volume: 100 mL) to make a total of 30 g of the stock solution and the propellant. (The mass ratio of the stock solution to the propellant was as shown in Tables 1 to 3). Compatibility was evaluated according to the following criteria. When the evaluation of the compatibility was not good, Test Examples 2 to 6 were not performed.

<Evaluation criteria of compatibility>
○ (good): no turbidity and precipitation × (defect): turbidity or precipitation

(Test Example 2: Dispersibility)
Each of the obtained stock solutions (aerosol spray hair styling composition) and each propellant is added to a pressure bottle (“Aerosol Test Bottle” manufactured by Tokyo High Polymer Co., Ltd., volume: 100 mL) to make a total of 30 g of the stock solution and the propellant. The mixture was filled as described above (the mass ratio of the stock solution to the propellant was as shown in Tables 1 to 3) and allowed to stand for 24 hours. After standing, the mixture was inverted and stirred, and the number of inversions until complete dispersion was determined. The dispersibility was evaluated according to the following criteria. In addition, about the comparative example 3, since the silica was not mix | blended with the undiluted | stock solution, evaluation was not performed. Also, when the evaluation of dispersibility was poor, Test Examples 3 to 6 were not performed.

<Evaluation criteria for dispersibility>
○ (Good): Completely dispersed by 1 to 2 reversal stirring Δ (Slightly poor): Completely dispersed by 3 to 5 reversal stirring × (Defect): Six or more reversal stirring until complete dispersion is necessary

(Test example 3: Hair setting ability at hair setting)
Five specialist panels uniformly spray each aerosol spray hairdressing agent on the hair of short hair wig (Lesson Mannequin: made by Eucalyptus Japan) from a distance of 15 cm for 3 seconds, and the hair upward from the root of the hair I got up and gave a haircut. Hair setting power at hair setting was evaluated according to the following criteria.

<Evaluation criteria for hair setting ability at hair setting>
○ ○ (very good): The shape of the trimmed hair is clearly kept, and the arrangement can be easily performed ○ (good): the shape of the trimmed hair is sharply held, but the arrangement power is somewhat inferior ((slightly poor ): Part of the hair does not stand up × (bad): the hair does not stand up

(Test Example 4: Finish after hair setting)
After evaluation of the above-mentioned test example 3 (hair setting power at the time of hair setting), five expert panels evaluated whether the wig hair became a natural finish with a mat according to the following criteria.

<Evaluation criteria for finishing after hair setting>
○ ○ (very good): There is a matte feeling, there is a natural finish without unnatural hair bundles ○ (Good): There is a matte feeling, there is a slight hair bundle feeling, but it is a natural finish ((slightly Poor): There is a feeling of luster or an unnatural hair bundle is formed x (defective): There is a feeling of luster and an unnatural hair bundle is formed

(Test example 5: Hair setting holding power)
After evaluation of the above-mentioned Test Example 4 (finish after hair setting), the wig after hair setting was allowed to stand in a constant temperature and humidity chamber (35 ° C., 80% RH) for 8 hours. After standing, five expert panels observed the wig's hair and evaluated the hair setting holding power according to the following criteria.

<Criteria for hair setting retention>
○ ○ (very good): Maintaining the initial hairdressing state ○ (Good): Slightly dripping hair from the initial hairdressing state ((Slightly poor): More than half of the hair initial hairdressing Has fallen from the state of time × (bad): almost all the hair has fallen from the state of the initial hair setting

(Test Example 6: Re-styling)
After the evaluation of the above-mentioned Test Example 5 (hair-holding power), the shape of the hair of the hair-dressed wig was broken. Thereafter, the hair was raised upward from the base of the hair and redressed. Five expert panelists evaluated the hair reassignability according to the following criteria.

<Criteria for evaluating hair reassignment>
○ ○ (very good): The shape of the trimmed hair is clearly kept, and the arrangement can be easily made ○ (good): the shape of the trimmed hair is clearly kept, but the arrangement power is somewhat inferior ((slightly poor ): Part of the hair does not stand up × (bad): the hair does not stand up

The composition and the results are shown in Tables 1 to 3 below.
