ONE-SHAPE PERMANANT HAIR COLOR OF PASTE TYPE

FIELD OF THE INVENTION The present invention relates to a one-formulation type oxidative permanent hair color in the form of paste, in particular, to a one-formulation type oxidative permanent hair color in the form of paste prepared by incorporating a treatment oil not containing water moisture selected from a fatty oil, a mineral oil, a plant oil and a silicone oil into a conventional one-formulation type oxidative permanent hair color comprising a dye, an oxidizing agent, a thickener and an additive selected from the group consisting of a chelating agent, a perfume, a surfactant, a pH modifier, a stabilizing agent, an oil-dispersing agent and a hair protecting agent. The present hair color makes it possible to overcome shortcomings such as inconvenience in production and application associated with the occurrence of dust, to color hair in low cost, to exhibit improved durability of hair coloring and treatment effect because the treatment oil is deeply penetrated into cortex layer of hair.

DESCRIPTION OF THE RELATED ART The present invention relates to a one-formulation type oxidative permanent hair color in the form of paste. More particularly, the present invention relates to a one-formulation type oxidative permanent hair color in the form of paste prepared by incorporating a treatment oil not containing water moisture selected from a fatty oil, a mineral oil, a plant oil and a silicone oil into a conventional one-formulation type oxidative permanent hair dye comprising a dye, an oxidizing agent, a thickener and an additive selected from the group consisting of a chelating agent, a perfume, a surfactant, a pH modifier, a stabilizing agent, an oil-dispersing agent and a hair protecting agent. The present hair color makes it possible to overcome shortcomings such as inconvenience in production and application associated with the occurrence of dust, to color hair in low cost, to exhibit improved durability of hair coloring and treatment effect because the treatment oil is deeply penetrated into cortex layer of hair.

A permanent hair color is called an alkaline hair color because its hair-coloring potential becomes higher in pH of alkaline region and also called an oxidative hair color because the coloring by use of it is executed with a dye generated by oxidative polymerization. The permanent hair color is classified into two-formulation type oxidative hair color and one-formulation type oxidative hair color. The two-formulation type hair color includes a first hair color formulation classified into cream, lotion and liquid phase and a second oxidative formulation classified into cream, lotion and liquid phase. In the application of the two-formulation type oxidative hair color, the first and second formulations are mixed in certain ratio just before use and applied to hair, and after allowing to stand for certain period of time, then washed away with soap or shampoo. In the application of the one-formulation type oxidative hair color, the hair color in the form of powder is mixed with water in certain ration just before use and applied to hair, and after allowing to stand for certain period of time, then washed away with soap or shampoo. The two-formulation type oxidative hair color comprises a hair color as a first agent formulation including an oxidative dye, an alkaline agent, a penetrant, a stabilizer, a wetting agent, a hair tonic, a colorant, an emulsifier, a perfume and the like, and a second formulation including an oxidizing agent, a penetrant, a stabilizer, a wetting agent, a hair tonic, a colorant, an emulsifier, a perfume and the like. The two-formulation type hair color is manufactured and prepared in two separated formulations thus resulting in increase in its production cost as well as the cost for obtaining raw materials and supplementary materials. To be free from the cost problem, the one-formulation type oxidative hair color is developed, comprising oxidative dye, oxidizing agent and thickener in one formulation, which contributes to decrease of production cost. However, the one- formulation type oxidative hair color leads to the shortcomings associated with the occurrence of powder dust, e.g., contamination of working environment, elicitation of allergy and rhinitis of a producer, adverse effects to health of a user and inconvenience in use. In addition, since oxidative dye and oxidizing agent are included in one formulation, the ingredients for protecting wet hairs are forced to use in very restricted manner. Thus, the one-formulation type hair color shows lower treatment effect and applicability thus resulting in poor applicability. NaBQ₃ + H₂0 _** NaB0₂ + H₂0 * NaB0₂ + H₂0 + O t

Furthermore, in the case that ingredients containing wet are used in the powderized one-formulation type oxidative hair color, oxidant such as sodium perborate and sodium percarbonate is likely to be decomposed and in turn undergone oxidative polymerization with oxidative dye to generate polymeric material. Such undesirable reaction prevents inherent performance of the hair color. Accordingly, the one-formulation type oxidative hair color is generally manufactured and commercialized only in the form of powder not containing water moisture. In other words, the two-formulation type oxidative hair color exhibits a few problems in treatment effect, hair-coloring potential and production cost, although it has excellent applicability and stability. Although the one-formulation type oxidative hair color makes it possible to color hair in lower cost, it shows disadvantages such as elicitation of allergy and rhinitis of a producer and a user by powder dust and inconvenience in use. Consequently, there remains a need for developing a one-formulation type oxidative hair color with novel formulation that can overcome the shortcomings described above. Therefore, the present inventors have made intensive researches to develop a hair color with novel composition, which makes it possible to color hair in low cost, to rapidly penetrate dyes, to exhibit improved durability of hair coloring and treatment effect, to prevent the elicitation of allergy and rhinitis of producer and user due to powder dust and to accomplish convenience in application. As a result, the present inventors have discovered that the incorporation of a treatment oil not containing water moisture selected from a fatty oil, a mineral oil, a plant oil and a silicone oil into a conventional one-formulation type oxidative permanent hair dye comprising a dye, an oxidizing agent, a thickener and an additive selected from the group consisting of a chelating agent, a perfume, a surfactant, a pH modifier, a stabilizing agent, an oil-dispersing agent and a hair protecting agent permits to accomplish the advantages described above. Furthermore, the present inventors have discovered a novel method for using a hair color, which comprises mixing the one-formulation type oxidative permanent hair dye in the form of ointment with shampoo or rinse usually used in the household and beauty shops in certain ratio, which increases the treatment effect and convenience in application. Accordingly, an object of this invention is to provide a novel one-formulation type oxidation permanent hair color, which exhibits longer durability of hair coloring, improves treatment effect and cost effectiveness, occurs no dust in production and application, and shows excellent convenience in application.

DETAILED DESCRIPTION OF THIS INVETNION

The present invention is directed to a one-formulation type oxidative permanent hair dye in the form of paste comprising a dye, an oxidizing agent, a thickener and an additive selected from the group consisting of a chelating agent, a perfume, a surfactant, a pH modifier, a stabilizing agent, an oil-dispersing agent and a hair protecting agent, the improvement of which comprises: wherein said one- formulation type oxidative permanent hair dye comprises: said hair color comprising 0.01-30.0 wt% of the said dye; 1.0-50.0 wt% of said oxidizing agent; 1.0-50.0 wt% of said thickener; and 0.1-70.0 wt% of said additive selected from the group consisting of the chelating agent, the perfume, the surfactant, the pH modifier, the stabilizing agent, the oil-dispersing agent and the hair protecting agent; and at least one treatment oils of 0.5-70.0 wt% selected from the group consisting of a fatty oil, a mineral oil, a plant oil and a silicone oil, wherein said treatment oil contains no water moisture.

The present invention will be described in more detail hereunder: The present invention relates to a one-formulation type oxidative permanent hair dye in the form of paste, prepared by incorporating a treatment oil not containing water moisture selected from a fatty oil, a mineral oil, a plant oil and a silicone oil into a conventional one-formulation type oxidative permanent hair dye comprising a dye, an oxidizing agent, a thickener and an additive selected from the group consisting of a chelating agent, a perfume, a surfactant, a pH modifier, a stabilizing agent, an oil-dispersing agent and a hair protecting agent. According to the instant invention, the disadvantages such as inconvenience in production and application due to the occurrence of dust in conventional powderized one-formulation type permanent hair colors may be overcome and the hair coloring may be operated in lower cost. In addition, since the treatment oil is deeply penetrated into cortex layer, the durability of hair coloring and treatment effect may be considerably improved. In the one-formulation type oxidative permanent hair dye in the form of paste, the dye comprises 0.01-30.0 wt% of oxidative dye selected from the group consisting of p-nitro-o-phenylenediamine, nitro-p-phenylenediamine, 2-methyl-5-hydroxyethyl aminophenol, 2-amino-5-nitrophenol, p-amino-o-cresol, m-aminophenol, o- aminophenol, p-aminophenol, nitro-p-phenylediamine hydrochloride, 2,4- diaminophenoxyethanol hydrochloride, Toluene-2,5-diamine hydrochloride ,m- phenylenediamine hydrochloride, p-phenylenediamine hydrochloride, toluene-2,5-diamine, m-phenylenediamine, p-phenylenediamine, N-phenyl-p-phenylenediamine, picramic acid, p-nitro-o- phenylenediamine sulfate , p-methylaminophenol sulfate, p-amino-o-cresol sulfate, m-aminophenol sulfate, o-aminophenol sulfate, p-aminophenol sulfate, 4- ethoxy-m-phenylenediamine sulfate, toluene-2,5-diamine sulfate , m- phenylenediamine sulfate, p-phenylenediamine sulfate , o-phenylenediamine sulfate, α-naphtol, resorcine, 2-methylresorcinol, gallic acid, catechol and pyrogallol, Other conventional dyes may be also used in the present hair color if the similar coloring effect may be anticipated. If the amount is less than 0.01 wt%, the hair coloring becomes poor; in case it exceeds 30.0 wt%, decolorization occurs at the time of washing with shampoo after hair coloring. The oxidizing agent may comprise 1.0-50.0 wt of sodium perborate, sodium percarbonate or its mixture. The thickener may comprise 1.0-50.0 wt% of at least one selected from the group consisting of gelatin, xanthan gum, carboxymethylcellulose, carbopol and hydroxyethylcellulose. The most prominent feature of this invention lies in the employment of the treatment oil which does not contain water moisture selected from the group consisting of a fatty oil, a mineral oil, a plant oil and a silicone oil, as well as the ingredients for hair color described above.

According to the present invention, the employment of the treatment oil enables the dye to be deeply penetrated into cortex layer, dusts to be prevented, and a treatment effect to be increased. The dye may be deeply penetrated into inner part of hair in which it undergoes oxidative polymerization to color hairs, which is responsible for improved durability of hair coloring. In addition, the ingredient for treatment exhibits its excellent efficacy and no occurrence of dusts during production or application permits to highly increase the convenience in production and application. In particular, the treatment oil may comprise 0.5-70.0 wt% of vaseline, paraffin, lanolin, wax, bees wax, squalane, liquid paraffin, glycerine, olive oil, castor oil, soybean oil, coconut oil, palm oil or silicone oil based on the total weight of the permanent hair color. If the amount is less than 0.5 wt%, the prevention of dust occurrence, durability of hair coloring and treatment effect is neglect; in the case of exceeding 70.0 wt%, the formulation becomes worse, so that its use is inconvenient. The present hair color may comprise the additive of 0.1-70.0 wt% selected from the group consisting of the chelating agent, the perfume, the surfactant, the pH modifier, the stabilizing agent, the dispersion oil agent and the hair protecting agent, that are conventional ingredients for hair color. The existing one-formulation type oxidative permanent hair dye in the form of powder is usually mixed with water at a certain ratio just prior to use, which leads to inconvenience in its application. However, the one-formulation type oxidative permanent hair dye in the form of paste may be prepared in the form of ointment, may easily color hairs with material for external use such as shampoo or rinse usually used in the household and beauty shops, and enable to increase the treatment effect and hair coloring potential. For example, for low-cost hair coloring, the one-formulation type oxidative permanent hair dye in the form of ointment is mixed with water. At this time, the mixing ratio, preferably, is 5:10-1 and may be adjusted to have excellent convenience in application. The one-formulation type oxidative permanent hair dye in the form of paste or ointment may be applied by mixing with a mixture containing at least two selected from the group consisting of water, tepid water, shampoo and rinse. The mixing ratio of the hair color to at least one selected from the group consisting of water, tepid water, shampoo and rinse, preferably, is 1:5-10 and may be adjusted in certain ratio. The employment of shampoo or rinse increases the treatment effect and convenience in application.
