ABSTRACT:

This application is the national phase under 35 U.S.C. §371 of PCT International Application No. PCT/JP00/04089 which has an International filing date of Jun. 22, 2000 which designated the United States of America, the entire contents of which are hereby incorporated by reference.
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hairdye composition containing indoline and/or indoline compound and laccase and, more particularly, it relates to an oxidative hairdye composition having little skin irritation, a good stability with a lapse of time, an excellent hair-dyeing effect, an excellent usability and particularly an ability of being prepared as a single preparation type.
BACKGROUND ART
Usually, an oxidative hairdye contains an oxidation dye (the first preparation) and an oxidizing agent (the second preparation) and, upon use, they are mixed to react and are applied to hair whereby white hair is dyed. When a commercially available oxidative hairdye is used, there is a risk of causing a rash because p-phenylenediamine, p-aminophenol, etc. compounded in the first preparation are skin-sensitive substances. On the other hand, with regard to the composition for the second preparation, most of it uses hydrogen peroxide as an oxidizing agent and, therefore, there is a possibility of damage of hair and skin.
Under such circumstances, indole compounds and indoline compounds have been proposed as substitutes for the conventional oxidation dyes (Japanese Laid-Open Patent Hei-8/40857) but the present situation is that using only such substances results in poor hair dyeing. On the other hand, as attempts for reducing the damage of hair by hydrogen peroxide, various means using an oxidase has been proposed. Examples of such an art are the use of laccase (U.S. Pat. No. 3,251,742 and Japanese Laid-Open Patent Hei-6/172145), the use of peroxidase (Japanese Laid-Open Patents Sho-47/10400 and Sho-53/32132) and the use of uricase (Japanese Laid-Open Patent Sho-63/246313). However, in most of the art disclosed herein, hydrogen peroxide is added or hair dyeing is conducted by effective utilization of hydrogen peroxide due to the characteristic feature of the enzyme whereby elimination of the problem by hydrogen peroxide is not fundamentally solved. Further, in the case of laccase, due to its unstable property during preservation, when it is compounded in the composition, reaction of oxygen with an oxidation dye in a headspace takes place whereupon insoluble aggregates are formed. Formation of such insoluble aggregates in a product is a very big problem as a hairdye. Accordingly, there is a big problem that it cannot be put on a market as a product unless such insoluble matters are suppressed.
DISCLOSURE OF INVENTION
The present invention has been accomplished under the above-mentioned circumstances and an object of the present invention is to offer an oxidative hairdye composition having little skin sensitivity, a good stability with a lapse of time, an excellent hair dyeing effect and an excellent usability.
In order to achieve the above-mentioned object, the present inventors have conducted an intensive study for achieving the above-mentioned object, found that an oxidative hairdye composition having little skin irritation, an excellent hair dyeing effect, a good stability even by preparing into a single preparation type and an excellent usability can be obtained when indoline and/or indoline compound and laccase are jointly used and have now achieved the present invention.
BEST MODE FOR CARRYING OUT THE INVENTION
When the present invention is illustrated in detail, indoline and/or indoline compound as developer(s) and laccase as an oxidizing agent are compounded in a hairdye composition of the present invention.
Examples of indoline and indoline compound are indoline, 5,6-dihydroxyindoline, N-methyl-5,6-dihydroxyindoline, N-ethyl-5,6-dihydroxyindoline, N-butyl-5,6-dihydroxyindoline, 4-hydroxy-5-methoxyindoline, 6-hydroxy-7-methoxyindoline, 6,7-dihydroxyindoline, 4,5-dihydroxyindoline, 4-methoxy-6-hydroxyindoline and salts thereof and each of them may be used either solely or two or more of them may be used jointly.
The compounding concentration of indoline and/or indoline compound in the composition of the present invention varies depending upon the frequency of use and the dosage form but, usually, it is 0.01-30% (% by weight; hereinafter, % will be used in the same sense) or, preferably, 0.05-20%.
When color change is desired in the hair dye composition of the present invention, a small amount of oxidation dye may be used as a coupler. Known couplers may be used as such an oxidation dye. For example, those which are described in “Standards for Materials for Quasi-Drugs,” such as 5-amino-o-cresol, o-aminophenol, m-aminophenol, p-aminophenol, 2,6-diaminopyridine, 5-(2-hydroxylethylamino)-2-methylphenol, N,N-bis(&bgr;-hydroxyl)-p-phenylenediamine sulfate, p-nitro-o-phenylenediamine, p-phenylenediamine, m-phenylenediamine, N-phenyl-p-phenylenediamine, resorcinol, 2-hydroxyl-5-nitro-2′,4′-diaminoazobenzene sodium sulfate, toluene-2,5-diamine, 5-amino-o-cresol sulfate, p-aminophenol sulfate, o-chloro-p-phenylenediamine sulfate, 4,4′-diaminodiphenylamine sulfate, p-methylaminophenol sulfate, p-phenylenediamine sulfate, m-phenylenediamine sulfate, toluene-2,5-diamine sulfate, 2,4-diaminophenoxyethanol hydrochloride, toluene-2,5-diamine hydrochloride, m-phenylenediamine hydrochloride, 2,4-diaminophenol hydrochloride, 3,3′-iminodiphenol, p-phenylenediamine hydrochloride, N-phenyl-p-phenylenediamine hydrochloride, N-phenyl-p-phenylenediamine acetate, 1,5-dihydroxynaphthalene, toluene-3,4-diamine, p-methylaminophenol, N,N′-bis(4-aminophenyl)-2,5-diamino-1,4-quinonediimine, o-aminophenol sulfate, 2,4-diaminophenyl sulfate and m-aminophenol sulfate, may be used in an appropriate amount either solely or jointly by combining two or more.
Further, direct materials which are frequently used together with such oxidation dyes such as 2-amino-4-nitrophenol, 2-amino-5-nitrophenol, 1-amino-4-methylaminoanthraquinone, nitro-p-phenylenediamine hydrochloride, 1,4-diaminoanthraquinone, nitro-p-phenylenediamine, picramic acid, sodium picramate, 2-amino-5-nitrophenol sulfate, nitro-p-phenylenediamine sulfate, p-nitro-o-phenylenediamine sulfate and p-nitro-m-phenylenediamine sulfate may be used as well.
Such a coupler may be used only when color of the dyed hair is to be changed and, in that case, its compounding concentration in the composition is 0.001-5% or, preferably, 0.005-2%. WO 99/36034, WO 99/36035, WO 99/36036, WO 99/36037, WO 99/36038, WO 99/36039, WO 99/36040, WO 99/36041, WO 99/36042, WO 99/36043, WO 99/36044, WO 99/36045 and WO 99/36046 in the name of L'Oreal discloses different kind of oxidizing dyes (developed substances or oxidation bases) and coupling components (coupling agents) which can also be used according to the present invention and which are hereby incorporated by reference.
The oxidation bases can in particular be selected among para-phenylenediamines, double bases, para-aminophenols, ortho-aminophenols and heterocyclic oxidation bases.
