DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0002]

2. Description of the Related Art A large number of aerosol foam hair cosmetics, such as hair styling foams and hair treatment foams, in which a stock solution of a hair cosmetic composition and a propellant are filled in a pressure-tight container, are widely used in view of their convenience. Have been.
However, these aerosol-type foam hair cosmetics use various propellants, so when designing products, safety, ozone layer destruction, air pollution, global warming, It is necessary to consider the response. For this reason, non-aerosol foam hair cosmetics which do not use a propellant have been developed.

[0003] However, conventional non-aerosol foam hair cosmetics have problems such as poor foam quality of foam discharged from a container, poor feeling such as stickiness, and insufficient setting property. Was. In addition, since the system generally contains a large amount of water, the drying property after application to hair was poor.

[0004]

As a technique for solving such a problem, for example, a technique of blending a high molecular compound in order to improve the setting property has been proposed. Gowatsuki derived from molecular compounds may occur. In addition, in order to improve the feel of the hair after drying, a technique of blending silicones such as dimethylpolysiloxane and polyether-modified silicone has been proposed, but these silicones affect the foaming property of the surfactant. In particular, in the non-aerosol type dosage form, there is a problem that foaming is remarkably deteriorated.

[0005] An object of the present invention is to provide a non-aerosol foam hair cosmetic composition which is excellent in foam amount and foam quality and excellent in texture.

[0006]

If a composition containing a specific silicone is filled in a non-aerosol foam discharge container such as a pump former,
It has been found that the ejected material is excellent in foaming properties and foam retention, has a fine foam texture, is creamy and soft, and can achieve both sufficient hair styling properties and good hair feel.

That is, the present invention provides a composition containing the following components (A) and (B) (A) polypropylene glycol or polyoxypropylene ether (B) polyether-modified silicone or amino-modified silicone. An object of the present invention is to provide a hair cosmetic filled in a discharge container.
