Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic for hair, which is intended to exert sufficient hair-styling power by being applied to the hair, and to provide a dry finish without hairiness after hair-dressing. Another object of the present invention is to provide a hair cosmetic composition that can re-form hair even if the hairstyle that has been once shaped is disturbed.

[0002]

2. Description of the Related Art Cosmetic products for hair used for styling hair have a hair styling power for styling and styling a disordered hairstyle, and can easily restore the original hairstyle once the hairstyle is disturbed for some reason. It is required to have a re-styling power that can be returned to a hairstyle. In conventional hair cosmetics, a large amount of an oily component has been blended without prescribing water in order to obtain hair styling power. Examples of such hair cosmetics include oily hair styling materials such as hair oil, pomade and tic. The oily hair styling materials have excellent hair styling power and can be easily reshaped even when the hair style is disturbed. It has excellent hair reshaping power. However, the use of oil-based hair styling materials has been reduced in recent years because they contain a large amount of oil-based ingredients, and are excellent in hair-styling and re-styling abilities, but they give sticky feeling and unnatural luster to the hair in recent years. Tend to. On the other hand, there is an aqueous hair styling agent as a hair styling agent in which the amount of the oil component is suppressed and water is added. Aqueous hair styling suppresses the amount of oily ingredients, so that it gives a refreshing feel without giving the hair the sticky feeling and unnatural luster that were disadvantages of oily hair styling. Therefore, it is widely used by those who want a dry finish.

[0003]

However, the conventional aqueous hair styling has the following problems. That is,
Since the amount of the oily component is suppressed, the sticky feeling and unnatural luster can be suppressed as compared with the oily hair styling, but the hair styling power is inferior. Therefore, in order to make up for this drawback, hair styling has been improved by blending a high molecular compound such as gum or resin. In the aqueous hair styling containing the polymer compound, the hair styling power is improved by drying the polymer compound on the surface of the hair to form a film. For this,
Once the hairstyle is broken, the hairstyle cannot be reshaped unless a liquid such as water is applied to the dried polymer compound in order to reshape the hairstyle again. No re-dressing was possible in the applied aqueous hair styling.

In view of the above circumstances, the present inventors have conducted intensive studies and as a result, by including polyoxyethylene reduced lanolin and a film-forming substance in hair cosmetics,
Having sufficient hair-styling power when applied to the hair, a dry feeling without stickiness can be obtained after hair-dressing,
The present inventors have found that even if the hairstyle is once disturbed, the hair can be easily reshaped without using a liquid such as water, and the present invention has been completed.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The hair cosmetic composition according to the present invention contains, as essential components, polyoxyethylene reduced lanolin and a film-forming substance. Hereinafter, each essential component will be described in detail. The first essential component of the cosmetic for hair according to the present invention is polyoxyethylene reduced lanolin. Polyoxyethylene reduced lanolin is obtained by adding ethylene oxide to hydrogenated lanolin and is a kind of nonionic compound widely used in cosmetics, but there is no example used in water-soluble hairdressing .

[0007] The polyoxyethylene reduced lanolin used in the present invention is not particularly limited as long as it is used as a cosmetic raw material. desirable. The reason for this is that if the number of moles of addition is less than 3, the required hydrophilicity cannot be obtained, the stickiness due to the polyoxyethylene reduced lanolin becomes strong, and the number of moles of addition is 7
If it is larger than 0, the hydrophilicity becomes too strong and the finished feeling is felt heavy, and in either case, it is not preferable.

In the present invention, only one kind of polyoxyethylene reduced lanolin may be used, but it is preferable to use a mixture of two or more kinds of polyoxyethylene reduced lanolin. In particular, in the present invention, at least one kind of polyoxyethylene reduced lanolin having an addition mole number of ethylene oxide of 3 to 19 (hereinafter simply referred to as component A) and a polyoxyethylene having an addition mole number of ethylene oxide of 20 to 70 are provided. It is desirable to mix and combine at least one of ethylene-reduced lanolin (hereinafter, simply referred to as component B). The blending amounts of the component A and the component B are not particularly limited, but it is preferable to blend the component B with 1/30 to 7 parts by weight per 1 part by weight of the component A. This is because when the amount of the component B is less than 1/30 parts by weight, the hair-dressing power is inferior. On the other hand, when it is more than 7 parts by weight, the hair-redressing power is inferior. Because. Polyoxyethylene reduced lanolin, which has a small addition mole number of ethylene oxide, exhibits an oily or viscous property, but becomes solid as the addition mole number increases, and its melting point tends to increase. For this reason, those having a small number of added moles have a re-shaping power after hair styling due to a low oil or melting point, but have a low hair styling power for shaping a disordered hairstyle and maintaining it for a long time. On the other hand, those having a large number of added moles have a high melting point and thus have an excellent hair-styling ability, but have a low hair-styling ability. Thus, by combining the two types of polyoxyethylene reduced lanolin of the A component and the B component having such contradictory properties, the advantage of one can be compensated for by the advantage of the other and both the effect of the setting force and the effect of the hair reshaping can be achieved. Can bring.

Further, in the present invention, it is preferable to prepare the polyoxyethylene reduced lanolin so that the melting point thereof is about 30 to 40 ° C. It has a melting point of about 30-40.
When the temperature is adjusted to ° C., the polyoxyethylene reduced lanolin is dissolved depending on the temperature of the hand, and the hair can be easily re-shaped.

The blending amount of the polyoxyethylene reduced lanolin is not particularly limited.
The content is preferably 0% by weight, more preferably 1.0 to 20.0% by weight. This means that if the amount is less than 0.5% by weight, the hair cannot be trimmed and adjusted,
Further, even if the content exceeds 40.0% by weight, not only no further effect can be expected, but also the finished feeling becomes heavy, which is not preferable in any case.
