Description

TECHNICAL FIELD The present invention relates to an aerosol foam hairdressing composition for use in an aerosol foam hairdressing agent discharged in a foam form (foam) from an aerosol container. The present invention also relates to an aerosol foam hair styling agent in which the above aerosol foam hair styling composition is filled.

Various hair styling compositions such as liquid, gel and grease are known. Of these, the grease-like hair styling composition (so-called hair grease or hair pomade) is generally superior to the liquid or gel-like hair styling composition in excellent properties for raising hair and for tightly gathering hair bundles. However, the grease-like hair styling composition has solid or paste-like properties and has no or little fluidity. Therefore, the grease-like hair styling composition is usually filled in a jar or the like. Then, at the time of use, the grease-like hair styling composition filled in a jar or the like is taken out from the container with a finger or the like and applied to hair or the like to perform hair styling (see, for example, Patent Documents 1 and 2).

On the other hand, as a hair styling agent having excellent applicability and usability to hair, an aerosol hair styling agent in which an aerosol hair styling agent composition is filled in an aerosol container is known (for example, see Patent Document 3). The aerosol hair styling agent has various forms such as an aerosol spray hair styling agent sprayed from an aerosol container and an aerosol foam hair styling agent discharged in a foam form from the aerosol container. In such an aerosol foam hair styling agent, a conventional grease-like hair styling composition has not been used as a hair styling composition filled in an aerosol container. The hair styling composition used for the aerosol hair styling agent must have fluidity so that it can be satisfactorily discharged from the aerosol container, and has a formulation design different from that of the grease-like hair styling composition.
