2. Description of the Related Art Conventionally, aerosol type foggy hair cosmetics have been used by dissolving a polymer compound having a film forming ability or an oil agent in a propellant represented by lower alcohol and liquefied petroleum gas. The polymer compound having a film forming ability is
Mainly, a set retention property and an oil agent are blended for imparting gloss and reducing stiffness. However, when a large amount of an oil agent is added to the foggy hair cosmetic, the stiffness is reduced, but there is a drawback that the hair becomes sticky or unnaturally glossy.

[0003] Also, with the recent diversification of hairstyle trends,
An increasing number of people prefer a natural finish, as if they had no hair cosmetics, while keeping their hairstyles in order. Here, the natural finish mainly means a non-sticky feel and an unnatural luster.

[0004] It is known to mix powders in atomized hair cosmetics, which is disclosed in JP-A-5-238922 and JP-A-2000-212051.
In general, when a liquefied petroleum gas or a liquefied gas such as dimethyl ether is used as a propellant, the specific gravity of the composition becomes lighter, the powder settles in the composition, and solidifies on the bottom of the container over time, and even when the container is shaken. Re-dispersion tends to be difficult.

Gives natural finish to hair. If it is a colored powder,
Changes in the color of the hair may result in an unnatural finish.

The particle size of the powder used in the present invention is 0.5 μm.
If it is less than m, the powder may be caught between cuticles after spraying on the hair, and washing may be difficult even if the hair is washed, which is not desirable. On the other hand, if the particle size is larger than 50 μm, the particles may easily fall off from the hair and the effect may be impaired. The particle size of the powder in the present invention refers to a volume-based average particle size, and the volume-based average particle size can be measured by a laser diffraction scattering method or an electric resistance method. Further, it is preferable that the powder to be blended with the present composition is composed of a spherical powder and a plate-like powder, because the dispersibility of the powder in the composition is improved.

In the present invention, the compounding amount of the powder is 0.1.
05 to 10% by mass. If the amount is less than 0.05% by mass, the effect of suppressing stickiness and the effect of reducing unnatural gloss cannot be obtained, which is not preferable. Further, if the content is more than 10% by mass, the effect is hardly improved, and the formation of a film of the polymer compound may be hindered.

In the present invention, the compounding ratio (B) / (C) of (B) the nonionic surfactant and (C) the powder having a particle size of 0.5 to 50 μm is in the range of 0.15 to 5. The non-stickiness and the dispersibility of the powder are further improved.
