Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition which is excellent in the styling process of hair, has no stickiness or stiffness after drying, can be set to a moist and soft touch, and has a long lasting set. .

[0002]

2. Description of the Related Art The hair setting agent which has been widely used in the past has mainly consisted of dissolving various film-forming synthetic polymers in water, lower alcohol, a mixed solvent thereof and the like and blending the resulting mixture as a setting base. is there. However, if such a synthetic polymer is used alone, it will be sticky during hair styling, stiff after drying, and sticky in high humidity environments.Therefore, in many formulations, various surfactants and oils are used as plasticizers and lubricants. Although they are blended, if these components are blended in an amount sufficient to improve the feel, the hair styling properties and the set keeping properties will be impaired. Therefore, such a system has not been obtained which sufficiently satisfies both the basic performance as a hairdressing agent and a good feeling in use.

As alternatives to these, there have been proposed those using a water-soluble polymer of a natural polysaccharide type such as chitin or chitosan derivatives or carrageenan as a set base (JP-A-52-156938, JP-A-2-15638). 1572
No. 14, JP-A-3-261715). However, although the formulation using these polysaccharide polymers has improved stickiness and stiffness as compared with the formulation using a synthetic polymer, the set retention is not sufficiently satisfactory. Hair cosmetics containing a natural polysaccharide and a synthetic polymer have also been reported (JP-A-62-289508).
And Japanese Patent Application Laid-Open No. 62-294606) cannot satisfy both the set force and the feel.

[0004] Examples of the hairdressing composition which is intended to hold a set by bonding between hairs with the above film-forming polymer include, for example, a foaming hairdressing composition of a hard type, a gel, and a spray. Immediately after hair styling, such a hair styling has a soft feeling that the hair bundle is soft because the polymer film is not completely solidified and the polymer film is not completely solidified.However, as the water evaporates with time and the film dries, the hair becomes dry. There is a drawback that the bundle becomes firm and stiff and changes to a rough feel, and the desirable feel immediately after finishing cannot be maintained for a long time.

[0005] On the other hand, hair styling products that hold sets by bundling hairs, as well as hair styling materials that bond between hairs with these polymer films, have high viscosity such as hair oils, hair creams, waxes, tics and pomades. There is a hairdressing agent that sticks the hair with an oily substance and holds the set as a bundle. These oil-based hair stylings do not harden the feel of the hair over time as the water in the formulation evaporates as in the case of the polymer compounding formulation. A feeling of hand-off is generated, which is not preferable in touch.

[0006]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a hair cosmetic which is excellent in both hair styling performance such as hair styling properties and set holding properties and good feel.

[0007]

The present inventors have conducted various studies to solve the above problems, and as a result, formulated a polysaccharide and a high molecular weight polyethylene glycol as set components,
In addition, the present inventors have found that a hair cosmetic composition having an unprecedented high kinking property and set holding performance and a good feel can be obtained by making the form of the cosmetic composition an emulsifying type. Was.

That is, the present invention provides an emulsified hair cosmetic containing a polysaccharide and polyethylene glycol having an average molecular weight of 500,000 to 5,000,000.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Examples of the polysaccharide used in the hair cosmetic of the present invention include natural saccharides and derivatives thereof. Specific examples of natural polysaccharides include carrageenan, xanthan gum, locust bean gum, guar gum, gum arabic, tragacanth gum, pectin and the like. Derivatives of natural saccharides include cellulose derivatives such as methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose hydroxypropyltrimethylammonium chloride, hydroxyethylcellulose hydroxypropyllauryl dimethylammonium ether, carboxymethyl chitin, hydroxypropyl Chitin or chitosan derivatives such as chitosan and chitosan-pyrrolidone carboxylate can be mentioned. Of these, anionic polysaccharides are more preferred due to the properties of the film, and carrageenan is particularly preferred. Even λ in carrageenan
The type has moderate viscosity, and is excellent in terms of ease of use and hair styling.

These polysaccharides can be used alone or in combination of two or more. The amount of the polysaccharides is not particularly limited, but better setting hair styling properties and set holding properties can be obtained and the feel after drying can be obtained. About 0.05 to 5% by weight, more preferably 0.5 to 2% by weight.
It is.

The molecular weight of the polyethylene glycol used in the present invention must be 500,000 to 5,000,000, more preferably 1,000,000 to 3,500,000, from the viewpoint of sufficient simplicity and feel during use. Within this range, the hair has excellent curling power, has no loose stringiness, and has a good feel. The amount of such polyethylene glycol is
Although it is not particularly limited, it is preferably 0.01 to 2% by weight, more preferably 0.03 to 0.5% by weight, which can provide a sufficient slimming property and has a good feel during hair styling.

In the present invention, it is important that the form is an emulsion type in order to achieve both hair styling properties, set holding properties and feeling of use. That is, in a hair styling composition containing a conventional setting polymer, an oil agent as a feel-enhancing component is dissolved or solubilized in the form of a hard set foam, gel, mist, or the like, and is used immediately before use like an aerosol foam. If the contents are mixed uniformly by shaking the container, they are mixed in a separated state.However, in the case of dissolution or solubilization, a sufficient amount to improve the feel is required to maintain the stability of the liquid. If the oil agent cannot be compounded and is mixed in a separated state, the oil agent starts to separate from the point when the agent is taken out of the container, thereby deteriorating the hair styling performance of the polymer. On the other hand, in the present invention, by blending the oil agent in an emulsified state, there is no stickiness at the time of application, the set component is excellent, and the hair can be kept moist and soft and the feel immediately after finishing can be maintained. It is.

In the present invention, in order to emulsify the system,
In addition to the above set components, it contains water, an oil agent and a surfactant. In addition, the emulsification system in the present invention may be either a water-in-oil type or an oil-in-water type.

The oil agent emulsified and blended in the hair cosmetic composition of the present invention can be appropriately selected and blended from those used in ordinary hair cosmetic compositions. Examples thereof include petrolatum, solid paraffin, and liquid paraffin. Hydrocarbons such as paraffin and squalane; olive oil, jojoba oil, lanolin, castor oil, cacao oil, natural animal and vegetable oils such as mink oil; lauric acid, myristic acid, palmitic acid, stearic acid, higher fatty acids such as coconut oil; ethylene Polyhydric alcohols such as glycol, propylene glycol, glycerin, diglycerin, pentaerythritol and sorbitol; lauryl alcohol, myristyl alcohol,

Above all, it is preferable to use a combination of a higher alcohol and a liquid oil such as liquid paraffin or silicone oil because a higher feeling improving effect can be obtained.

The amount of these oils is preferably about 1 to 15% by weight from the viewpoint that a sufficient feeling improving effect can be obtained and the stability of the emulsion and the set retention are good. Here, when the higher alcohol and the liquid oil are used in combination as described above, the liquid oil is preferably about 1 to 10% by weight with respect to 1 to 5% by weight of the higher alcohol from the viewpoint of stability and feel.

The surfactant used for emulsification in the hair cosmetic of the present invention is appropriately selected from cationic, anionic, nonionic and amphoteric surfactants used in ordinary hair cosmetics.
