Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention quickly and effectively suppresses dullness and stiffening of hair due to perm, hair color, and bleaching, and at the same time, effectively prevents damage to hair when using a dryer or brushing. The present invention relates to a hair cosmetic that can be suppressed.

[0002]

2. Description of the Related Art A stock solution of a hair cosmetic composition and a propellant are filled in a pressure-resistant airtight container,
Aerosol type foamy hair cosmetics such as hair styling foams and hair treatment foams are widely used because of their convenience. However, since these aerosol-type foamy hair cosmetics use various propellants, when designing products, safety, ozone depletion, and
It is also necessary to consider measures to protect the global environment such as air pollution and global warming. Therefore, non-aerosol type foamy hair cosmetics that do not use a propellant have also been developed.

However, the conventional non-aerosol type foamy hair cosmetics have problems that the quality of the foam discharged from the container is poor, the feel such as stickiness is poor, and sufficient setting property cannot be obtained. It was

On the other hand, in recent years, beauty treatments such as hair coloring and bleaching have been rapidly spread, and in combination with other chemical treatments such as the conventional permeation, the lipids of the hair have been leaked out and dried. The hair feels worse, such as sticking and stiffening, and the cuticle is curled up, peeled off, split ends,
The number of cases in which hair damage such as broken hair occurs is also increasing.

[0005]

Therefore, the amount of foam and the quality of the foam are excellent, and the dryness and roughness of the finished hair are suppressed even when the hair has been subjected to a plurality of chemical treatments. It has been desired to develop a new technique for realizing a non-aerosol type foamy hair cosmetic that can effectively suppress damage to the hair at the time.

[0006]

The inventor of the present invention can fill a non-aerosol type foam discharge container such as a pump former with a composition containing an organic acid, a specific organic solvent, silicones and a surfactant. It has excellent foaming properties, fine bubbles, is creamy and soft, gives a good hair feel, and even in the case of hair that has been subjected to multiple chemical treatments, dryness and stiffening at the time of finishing are suppressed, It has been found that a foamy hair cosmetic composition capable of effectively suppressing hair damage such as curling of cuticles, split ends, and broken hair can be obtained.

That is, the present invention provides a composition containing (a) an organic acid, (b) an organic solvent selected from benzyl alcohol, benzyloxyethanol and propylene carbonate, (c) silicones and (d) a surfactant. The present invention provides a hair cosmetic prepared by filling a non-aerosol type foam discharge container.
