Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emulsified cosmetic for hair, and more particularly, to an oil-in-water emulsified cosmetic for hair. It is an object of the present invention to provide an emulsified cosmetic for hair that can be retained, does not give a bad touch such as a stiffness or a sticky feeling, and can impart gloss and elasticity.

[0002]

2. Description of the Related Art As a hairdressing agent that can prepare a hairstyle and maintain the prepared hairstyle,
Oil-based hairdressings and liquid hairdressings are used. Examples of the oil-based hairdressing agent include hair oil, pomade, and tic. Oil-based hairdressing products do not contain water and contain a large amount of oily components such as vegetable oils and waxes, so they have excellent hair-dressing power, so they are mainly used by people with hard hair quality like many Japanese. Have been. Examples of the liquid hair styling agent include a hair cream and a hair liquid. Liquid hair styling contains water and oily components, which can be used as a water-in-oil type or oil-in-water type emulsion using various surfactants to provide a refreshing feel. Widely used by those who want a soft finish.

[0003]

However, the conventional hair styling has the following problems. First, the oil-based hairdressing agent contains a large amount of oily components, so that it has excellent hair-styling power, but has a problem that it gives sticky feeling and unnatural luster to the hair and that it is hard to remove with shampoo. Further, it is difficult to change the hair so that the hair has a shape desired by the user, and to maintain the change for a long time. Further, the conventional liquid hair styling suppresses stickiness and unnatural luster and is easy to wash hair, but has a problem in that hair styling power is inferior to oil-based hair styling. By combining film-forming substances such as gums and resins with liquid hair styling materials, strong hair styling power can be imparted without giving the oily hair styling a sticky feeling or unnatural luster. It is. However, in this case, since the hair is fixed by the coating, there is a problem that the stiffness is given, the touch of the hair is poor, and the original elasticity of the hair is lost.

In view of such circumstances, the present inventors have conducted intensive studies and found that an oil-in-water emulsion comprising polyoxyethylene beeswax and a nonionic surfactant was formed to give a sticky feeling and oily non-stickiness. It has been found that the hair can be given a high hair styling power without imparting a natural luster, and that the hair can be excellent in elasticity without giving a feeling of stiffness such as stiffness, and the present invention has been completed. .

[0015] In the emulsified cosmetic for hair according to the present invention,
When blending the above-mentioned oily component, the blending amount is not particularly limited, but is preferably 1.0 to 50.0% by weight, more preferably 3.0 to 40.0% by weight. . This is because if the composition is less than 1.0% by weight, the effect of the composition cannot be obtained, and even if the composition is more than 50.0% by weight, no more effect can be expected, and also the hair This is because in any case, it is not preferable in order to give a sticky feeling or an unnatural luster.
