ABSTRACT:
RELATED APPLICATIONS
This application claims the priority of Japanese Patent Application No. 11-156792 filed on Jun. 3, 1999 and Japanese Patent Application No.2000-95024 filed on Mar. 30, 2000, which are incorporated herein by reference.
FIELD OF THE INVENTION
The present invention relates to a hairdressing cosmetic preparation and a hairdressing method using the same; and, in particular, to an improvement in a setting agent thereof.
BACKGROUND OF THE INVENTION
Among hair cosmetic preparations conventionally in wide use, hairdressing cosmetic preparation for hairdressing and set-keeping include those in which a hairdressing oil component such as polypropylene oxide monobutyl ether, polypropylene oxide glyceryl ether, or their phosphate ester or salt is dissolved in or emulsified with water, a lower alcohol, their mixed solvent, or the like; those in which a high-molecular compound having a coat-forming property and a setting property is dissolved in water, a lower alcohol, their mixed solvent, or the like; and so forth.
Although the hair applied with the former hairdressing cosmetic preparations compounded with the hairdressing oil component is free of stiffness, there have been problems that the hair glares is so sticky that its touch is not so favorable.
On the other hand, although the latter hairdressing cosmetic preparations compounded with the high-molecular compound are excellent in their action of securing hairs to each other and keeping their setting, there have been problems that the hair applied with the hairdressing cosmetic preparations has stickiness and is not smooth in the process of applying, drying and finishing, and become severely stiff after drying.
When a large amount of a polymer as a setting agent is compounded into the preparation in order to enhance its hair setting effect, in particular, combing has become more difficult upon blowing by use of a drier or the like, and stiffness in hair or separation (flaking) of the setting agent has occurred after the drying.
For overcoming such problems, improvements have been proposed by compounding various additives such as polyhydric alcohols, their derivatives, lanolin, and esters. However, the setting effect may deteriorate along with their addition, so that there have been cases where satisfactory hairdressing preparations are not obtained. Similarly, although the touch of hair improves when the amount of the polymer used as a setting agent is lowered, hairdressing preparations satisfactory in terms of the setting effect have not been obtained.
SUMMARY OF THE INVENTION
The present invention is performed in view of the above-mentioned problems of the prior art, and it is an object of the present invention to provide a hairdressing cosmetic preparation having a favorable touch and an excellent setting effect.
The inventors have carried out diligent studies in order to achieve the above-mentioned object and, as a result, have found that a favorable touch and a high setting effect can be obtained if a polymer which becomes to gel upon heating is compounded as a hairdressing effective component into a hairdressing cosmetic preparation and heated with a dryer or the like when applied to hair, thereby accomplishing the present invention.
Namely, a hairdressing cosmetic preparation in accordance with the present invention is characterized by comprising a heat-gelling polymer which becomes to gel upon heating.
In the hairdressing cosmetic preparation, it is preferable that the heat-gelling polymer has a gelling temperature of 60° C. or higher.
Also, in the hairdressing cosmetic preparation, the heat-gelling polymer is preferably a polysaccharide.
Also, in the hairdressing cosmetic preparation, the heat-gelling polymer is preferably &bgr;-1,3-glucan.
Also, in the hairdressing cosmetic preparation, the heat-gelling polymer is preferably &bgr;-1,3-xylan.
Also, in the hairdressing cosmetic preparation, the heat-gelling polymer is preferably curdlan.
Also, in the hairdressing cosmetic preparation, it is preferable that the heat-gelling polymer which is powder in an ungelled state and/or in a dissolved neutralized gel state is dispersed into the cosmetic preparation.
Also, in the hairdressing cosmetic preparation, it is preferable that water is further contained therein.
Also, in the hairdressing cosmetic preparation, it is preferable that the heat-gelling polymer is 0.001% to 10% by weight in the cosmetic preparation.
Also, in the hairdressing cosmetic preparation, it is preferable that a fine particle powder is contained therein.
Also, in the hairdressing cosmetic preparation, the fine particle powder is preferably fine particle titanium dioxide.
Also, in the hairdressing cosmetic preparation, the fine particle powder is preferably fine particle silica.
Also, in the hairdressing cosmetic preparation, the fine particle powder is preferably silica-surface-treated fine particle titanium dioxide.
A hairdressing method in accordance with the present invention is characterized by comprising the steps of shaping hair while applying thereto a composition comprising a heat-gelling polymer, and then fixating the hair with a hot wind.
In the method, it is preferable that water exists upon application to the hair and the hot wind is 80° C. or higher.
BEST MODES FOR CARRYING OUT THE INVENTION
The hairdressing cosmetic preparation of the present invention includes a heat-gelling polymer which becomes to gel upon heating. After the hairdressing cosmetic preparation of the present invention is applied to hair, the aimed hair style is fixated with a heat from a drier or the like.
The heat-gelling polymer used in the present invention gels at a heating temperature of 60° C. or higher. Examples thereof include heat-coagulable proteins, collagen, heat-coagulable starches, and the like. The molecular weight is, but not limited thereto, within the range from 10,000 to 10,000,000 normally. Among them, preferable are heat-gelling polysaccharides, and more preferable is &bgr;-1,3-glucan or &bgr;-1,3-xylan.
Further, in &bgr;-1,3-glucan, straight-chain type curdlan is the most preferable from the viewpoint of its stability in supply and its cost. When &bgr;-1,3-glucan other than curdlan, for example, such as scleroglucan, sclerotan, schizophyllan, lentinan, paramylon, callose, laminaran, or the like is processed by such a method as mild Smith decomposition (Polym J. 13(12) 1135-1143 (1981)), a polymer having properties similar to those of curdlan can be obtained.
More specifically, curdlan is a kind of polysaccharides produced by a microorganism (Alcaligenes faecalis var. myxogenes, various strains of Agrobacterium, or Rhizobium). Its constituent sugar is D-glucose alone, and 99% of its glucoside bonds is &bgr;-1,3-bond.
Known as a method for preparing a dispersion is one comprising the steps of adding water to curdlan powder and vigorously stirring the mixture by use of a high-speed homogenizer, cutter mixer, or the like or the steps of adding curdlan to warm water of about 55° C. while stirring it with a hand, a propeller stirrer, or the like and then cooling the mixture, thereby yielding a uniform dispersion of ungelled powder. A gel is formed when this aqueous dispersion is heated.
Also, without heating, a gel can be formed if curdlan is once dissolved in an alkaline aqueous solution of sodium hydroxide or the like and then is neutralized by addition of a neutralizing equivalent amount of an acid such as hydrochloric acid. In this specification, such a gel is referred to as dissolved neutralized gel. A stable dispersion can be obtained if this dissolved neutralized gel is vigorously stirred by a homogenizer or the like so as to be finely crushed. A gel is formed when this dispersion is heated. Here, a gel, that has a similar nature with the dissolved neutralized gel, can also be made when curdlan dissolved in the alkaline aqueous solution is neutralized with carbonic acid gas or the like while standing still, or when the alkali such as sodium hydroxide is eliminated by use of a dialysis membrane. A gel, that has a similar nature with the disso
