Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol-type foamy hair cosmetic composition which is excellent in foaming property, has fine foam texture, is creamy and soft.

[0002]

2. Description of the Related Art Aerosol type foamy hair cosmetics such as hair foams are composed of a composition (stock solution) to be sprayed and a propellant enclosed in a pressure-resistant airtight container. At the same time, the liquefied gas contained in the undiluted solution vaporizes under atmospheric pressure, causing the undiluted solution to swell into a foam. In addition to water and a surfactant, various oil agents and polymers are added to the stock solution of the foamy hair cosmetic composition in order to enhance the feel and setting properties of the hair.

However, when an oil agent or a polymer is added to the undiluted solution as described above, it is necessary to add a relatively large amount in order to obtain these sufficient effects.
There is a problem that the foam quality and the feeling of use deteriorate, and the amount of these components blended is limited. As described above, none of them have a satisfactory balance between foam quality and performance.

Therefore, the texture of the foam is fine and the quality of the foam is good,
There has been a demand for a foamy hair cosmetic composition in which the blending amount of an oil agent or a polymer is not limited.

[0005]

Under such circumstances, as a result of intensive studies by the present inventors, as a solvent for water-added aerosol spray or non-aerosol pump spray, the viscosity is suppressed and the mist diameter is reduced, If you use dimethoxymethane, which is used for the purpose of increasing the drying property,
The present invention has been completed by finding that a foamy hair cosmetic composition having excellent foaming properties, fine foam texture, creamy and soft texture can be obtained.
