(Examples 1-7 and Comparative Examples 1-12)

The compounding component shown in following Tables 1-3 was mix | blended (mixing unit is mass%), and the aerosol spray hair dressing composition (stock solution) which has a composition shown in following Tables 1-3 was prepared. The obtained aerosol spray hair dressing composition (stock solution) was filled into an aerosol spray container (volume 95 mL). Subsequently, the aerosol valve was clinched in the aerosol spray container, and the propellant shown in Tables 1 to 3 below was filled from the stem, and a button suitable for the stem was attached to prepare an aerosol spray hair dressing agent.

(evaluation)

Five expert panels performed the following evaluations.

(Test Example 1: Compatibility)

Fill each obtained stock solution (aerosol spray hair dressing composition) and each propellant into a pressure-resistant bottle ("Aerosol test bottle" manufactured by Tokyo Kobunshi Co., Ltd., capacity: 100 mL) so that the total amount of the stock solution and the propellant are 30 g in total (stock solution and propellant and Mass ratio is as shown in Tables 1-3. Compatibility was evaluated according to the following criteria. In addition, when the compatibility evaluation was bad, Test Examples 2-6 were not performed.

<Evaluation standard of compatibility>

○ (good): No turbidity or precipitation

× (bad): cloudy or precipitated

Test Example 2: Dispersibility

Fill each obtained stock solution (aerosol spray hair dressing composition) and each propellant into a pressure-resistant bottle ("Aerosol test bottle" manufactured by Tokyo Kobunshi Co., Ltd., capacity: 100 mL) so that the total amount of the stock solution and propellant are 30 g in total (stock solution and propellant and Mass ratio was as shown in Tables 1-3, and left still for 24 hours. After standing, the number of inversions until inversion stirring and complete dispersion was determined. Dispersibility was evaluated according to the following criteria. In addition, about the comparative example 3, since silica was not mix | blended with the stock solution, evaluation was not performed. In addition, when evaluation of dispersibility was defective, Test Examples 3-6 were not performed.

<Evaluation criteria of dispersibility>

(Good): It disperse | distributes completely by 1-2 inversion stirring.

△ (slightly poor): completely dispersed in 3 to 5 times of reverse stirring

× (poor): 6 or more times of reverse stirring is required before complete dispersion

(Test Example 3: Hairstyling Power in Hairdressing)

Five professional panelists spray each aerosol spray hairdresser uniformly on the hair of short hair wig (Lesson Mannequin: Yukari Japan Co., Ltd.) at a distance of 15 cm for 3 seconds, and raise the hair upward from the root of the hair. Hairdressing was carried out. Hairdressing power at the time of hairdressing was evaluated according to the following criteria.

<Evaluation standard of hairstyling power at the time of hairdressing>

○○ (very good): The shape of the hair to be kept is clearly maintained, and the arrangement can be facilitated.

○ (good): The shape of the hair is kept clearly, but the arrangement is slightly inferior

△ (slightly poor): part of the hair does not stand up

× (poor): hair does not stand up

(Test example 4: finishing after hairdressing)

After evaluation of the test example 3 (styling power at the time of hairstyling), five professional panels evaluated whether the hair of the wig is matte and natural finish according to the following criteria.

<Evaluation standard of finish after hairdressing>

○ (very good): There is a feeling of mat and is a natural finish without the unnatural hair bundle

○ (good): There is a feeling of mat, and there is a feeling of hair bundle a little, but is a natural finish

△ (slightly poor): Glossy or unnatural hair

× (poor): There is glossiness and an unnatural hair bundle is generated

Test Example 5: Hairstyling Holding Force

After the evaluation of the test example 4 (finish after finishing hairdressing), the wig after hairdressing was left standing in a thermo-hygrostat (35 degreeC, 80% RH) for 8 hours. After standing, five professional panels observed the hair of a wig and evaluated the hair-setting retention according to the following criteria.

<Evaluation standard of hairdressing holding power>

○ (very good): The state at the time of initial hairdressing is maintained.

○ (good): There is a little hair flowing from the state at the time of initial hairdressing

(Trivial defect): More than half of hair flows down from the state of initial hairdressing

X (poor): Nearly all hairs flow out from the state of initial stage hairdressing.

(Test Example 6: Recurrence)

After evaluation of the said Test Example 5 (hair-holding force), the shape of the hair of the hairdressed wig was scattered. After that, the hair was raised from the root of the hair upwards and reorganized. Five expert panels evaluated recurrence according to the following criteria.

<Evaluation standard of financial volatility>

○○ (very good): The shape of the hair to be kept is clearly maintained, and the arrangement can be facilitated.

○ (good): The shape of the hair is kept clearly, but the arrangement is slightly inferior

△ (slightly poor): part of the hair does not stand up

× (poor): hair does not stand up
