Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel composition for dyeing human hair. More particularly, the invention relates to said dyeing composition comprising a bismuth salt and a catalyst component.

In the cosmetics industry, pigments have been used in various forms, primarily for the coloring of human hair. For such applications, the use of Many restrictions have been placed on dye systems.

In the past, bismuth-containing dye systems have been used for human hair coloring, particularly in applications involving the darkening of gray hair in men and women.

In this field of use of bismuth-containing dye systems, various additives and enhancers have been proposed in order to improve the effects achieved. Many dye formulations and dyeing mechanisms have also been reported.

Despite the long history of the dyeing industry, a completely satisfactory dyeing composition for human hair has not yet been obtained. Disadvantages of various known hair dyeing compositions include, for example, the relatively low degree of coloration imparted to the treated hair and/or the difficulty in applying the dye to the human hair fibers to achieve the desired coloration. The efficiency and ease of doing so is relatively low.

Although considerable efforts have been made to achieve improved dyeing systems for human hair, known means of improving basic hair dyeing methods have generally been only partially successful.

Although the methods developed have been helpful in ameliorating one or more of the deficiencies exhibited by a given dyeing system, they often make other properties of the dyeing system more troublesome or cause problems with human hair. It did nothing to improve the similar properties of other staining systems that have been used.

A method for dyeing human hair comprising applying a composition comprising an aqueous solution of a tangent dye mixed with 5-1% by weight of 2-phenoxyethanol alpha and 5-12% by weight of ethyl glycol acetate. Again, no mention is made of the use of the bismuth-containing dye system which is the subject of the invention or of the catalyst components disclosed in the invention.

Thus, the dye systems and dyeing methods of the present invention provide highly desirable enhancements to the efficacy of dye systems used to treat human hair (including the use of catalysts and bismuth salts exhibiting unique properties). The system or dyeing method is
It is not mentioned in any of the conventional documents listed above,
It's not even suggested.

It is therefore an object of the present invention to provide a human hair dyeing composition comprising a bismuth salt and a catalyst component, which provides a significant improvement in human hair coloring efficacy compared to similar hair dyeing compositions of the prior art. The goal is to provide the following.

Another object of the present invention is to provide a composition comprising a bismuth salt and a catalyst component that achieves the desired degree of human hair coloration in a shorter time than previously expected by making bismuth-containing dye systems similar to conventional methods. An object of the present invention is to provide a hair dyeing method using the same.

These and other objects of the invention will become apparent from the detailed description below.

Briefly, according to the present invention, a catalyst for dyeing human hair comprising a bismuth salt and a catalyst having a chemical structure containing either an oxygen atom having a resonant double bond or an oxygen atom of an ether group bonded to a carbon atom A composition is provided, characterized in that the catalyst used has a high solubility in water and a molecular weight of about 50-170.

The present invention also provides triethanolamine, at least one sulfur-containing component, and Triton X1 in the bismuth salt and the catalyst component.
To provide a novel composition for dyeing human hair, which is obtained by mixing a composition consisting of 0.0 and water.

When using bismuth-containing dye systems to color human hair, they must have a chemical structure containing either an oxygen atom with a resonant double bond or an oxygen atom of an ether group attached to a carbon atom and have a high susceptibility to water. The incorporation of a catalyst component having a solubility and a molecular weight of about 50 to 170 greatly contributes to increasing the degree of coloration to be achieved, while shortening the time required to bring the desired degree of coloration to a given hair sample. I found that it also helps.

Hair dyeing compositions such as the compositions of the present invention are comprised of compositions that make available the soluble sulfur ions and bismuth ions necessary to ultimately deposit in the form of bismuth sulfide on the hair to be treated. Various bismuth salts, such as bismuth citrate, which are insoluble in aqueous solutions, are commonly used with triethanolamine and triton
It is commonly used with commercially available ingredients such as Ba5a's Wetting Agent (Wetting Agent) and other ingredients including sulfur and sodium thiosulfate.

Since bismuth sulfide is normally insoluble in aqueous media, it is difficult for its ions to penetrate the hair fibers and form bismuth sulfide molecules there to impart the necessary layer color. Therefore, the bismuth sulfide molecule is
When actually deposited on the hair to be treated, it is generally in the form of bismuth sulfide (mono) with a molecular weight of 24,107, which imparts a gray color to the hair, or the molecule 115, which imparts a brownish-black color to the hair.
14.20 bismuth trisulfide shape.

It is hypothesized that the catalyst components described provide a convenient means by which the negative oxygen of the catalyst can attract positive bismuth ions and the positive carbon of the catalyst can attract negative sulfur ions.

The attracted ions, after entering the hair fiber and subsequent drying, combine within the fiber to form a colored sulfur, which involves a complex interaction of the dye system.
It has also been found that the presence of an excess of sulfur ions is required to provide the sulfur necessary for the formation of bismuth sulfide or trivalent bismuth oxide within human hair fibers.

The compound may be selected from the group consisting of compounds with high solubility in water and molecular weight.

It has been found that when using a base composition consisting of a soluble bismuth salt dye system and the aforementioned ingredients from about CL5 to about 20% by weight, significant improvements in the coloration imparted to human hair can be achieved. For optimum results, preferably about 10 parts by weight of catalyst component are used, based on the total weight of the hair coloring composition.

Cool the mixture to 40°C and, stirring constantly,
Sodium thiosulfate was added.

In a separate container, sulfur and Triton X100 were dispersed in 10≦water to obtain a slurry. This slurry is then added to about 2

The milled slurry was added to the mixture of bismuth citrate, TEA and sodium thiosulfate with constant stirring, the remaining % water was used to rinse the container containing the slurry, and this rinse water was added to the mixture.

The catalyst components were then added to the mixture with further stirring.

The resulting hair dyeing composition was applied to a human hair sample in seed blue for 1 minute and then allowed to dry.

The color of human hair samples after 4124 hours of drying was visually evaluated and graded on a scale of 1-10. Here, 1 indicates the results obtained without using the catalyst component in the basic composition of Table 1,
Also, 10 represents the optimal effect. The reason for waiting 24 hours in this color comparison is because a gradual darkening occurred, as observed in Example xX.

S 10 The above results illustrate that catalyst components such as urea having a carbonyl attached to the nitrogen atom are ineffective in the dye system of the present invention. Similarly, the presence of elemental sulfur in the dyeing system is critical for effective formation of bismuth sulfide. Also, the use of other heavy metal salts such as vinegar lead is also ineffective, and the catalyst component is not lead salt but bis! It is found to be useful and advantageous with salts.
