Description

  The present invention relates to an aerosol spray hair composition. More specifically, the present invention relates to a non-aqueous aerosol spray hair composition and a hair aerosol spray containing the composition.

Conventionally, as a hair composition, there is a type of hair styling with a film-forming agent or an oil such as oil, and in recent years, the hair is not stiff, it can be laid into a natural hairstyle, and re-styling is also possible. For this reason, hair waxes that style hair with solid oil are preferred. However, since hair wax is used by extending with palm, there is a problem from the viewpoint of usability such that the hair wax tends to become uneven and the hands get dirty.
On the other hand, the aerosol spray for hair has the advantage that it can be uniformly applied directly to the hair without soiling the hand and is easy to use. However, conventional aerosol spray-type hair compositions have problems that the hair becomes stiff, sticky, and oily when hair is formed with a film-forming agent or oil.

In order to solve such problems, aerosol-type hair styling agents have been proposed that have excellent hair styling properties, reduce wrinkling and stickiness, and can be applied uniformly to hair. For example, hair styling containing monovalent lower alcohol, anionic resin, water, surfactant and propellant (see Patent Document 1), higher alcohol, surfactant, ethanol, water and liquefied petroleum gas. Aerosol composition (see Patent Document 2), mist-like hair cosmetic containing solid or paste oil, liquid oil, film-forming agent, nonionic surfactant, water and propellant (see Patent Document 3) In addition, spray hair wax (see Patent Document 4) containing cetanol and polyoxypropylene diglyceryl ether has been proposed.
