Abstract

PROBLEM TO BE SOLVED: To obtain a hair dye composition capable of improving the permeability of a dye into hair and providing a good dyeing power with a smaller amount than that of a conventional dye by making a multiple agent type hair dye generate heat at the time of mixing for use. SOLUTION: This composition is obtained by making a multiple agent type hair dye generate heat at the time of mixing for use. An oxidation-reduction reaction, a dissolving reaction and a neutralizing reaction are cited as the principle in generation of heat and the energy released during the respective reactions becomes a heat source. An environment so as to initiate the respective reactions just before application may be created for utilizing the respective reactions. That is, the utilization of the reactions is achieved by mixing an oxidizing agent with a reducing agent, an organic solvent and water or an acid and a base separated and stored in the multiple agent type just before the use. For example, a combination of sodium (pyro)sulfite used as the reducing agent, hydrogen peroxide used as the oxidizing agent, a combination of sodium hydroxide and/or potassium hydroxide used as the base and hydrochloric acid used as the acid, etc., are preferably adopted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dye composition, and more specifically, generates heat when mixed on application to hair.
The present invention relates to a multi-drug type hair dye composition having an effect of enhancing hair dyeing power.

[0002]

2. Description of the Related Art Hair dyes include permanent hair dyes which react an oxidizing dye and an oxidizing agent when applied to hair, semi-permanent hair dyes which contain a direct dye and penetrate the hair with a solvent, and There is a temporary hair dye which causes a pigment to adhere to the hair surface using a resin or the like. The temporary hair coloring agent only physically attaches the dye to the hair, and in order to improve the hair dyeing power, a method of increasing the dye concentration or selecting a suitable resin has been adopted. On the other hand, semi-permanent hair dyes allow the dye to penetrate into the interior of the hair and dye the hair. Permanent hair dyes have a mechanism of chemically reacting the dye that has penetrated the interior of the hair to dye the hair. . Therefore, participation in various physicochemical factors is important for improving the hair dyeing power of the semi-permanent hair dye and the permanent hair dye. In general, as a method of improving the hair dyeing power of semi-permanent hair dyes and permanent hair dyes, increase the dye concentration, or increase the application time to increase the amount of dye penetrated into the hair, or by using a warmer or the like A method has been adopted in which the hair is heated to promote a chemical reaction for coloring the dye.

[0003]

As described above, there are various methods for improving the hair dyeing power, but there are also problems. When the amount of the dye is increased, the hair dyeing power is increased, and at the same time, the scalp, which is generally less dyeable than the hair, is dyed, and the stain becomes conspicuous. In addition, applying for a longer time than the instructed application time means that the contact time with the skin also becomes longer, which is not preferable in terms of safety. In hairdressers, hair dyeing power is improved by using a heater or the like, or application time is shortened,
It is virtually impossible to perform the same operation at home.

[0004] Further, depending on the temperature difference of the head and the degree of damage to the hair, the vicinity of the root and the tip of the hair tend to be dyed, and the middle part tends to be less likely to be dyed. In order to uniformly and uniformly dye the whole, an advanced coating technique was required.

[0005]

Means for Solving the Problems The inventors of the present invention have made intensive studies to solve the above-mentioned problems, and as a result, have found that the problems can be solved by providing a hair dye which generates heat when hair is applied. The present invention has been completed. In other words, the hair dye composition of the multi-drug type is characterized by generating heat when mixed and used.

The hair dye composition of the present invention can improve the permeability of the dye into the hair by generating heat, and can accelerate the oxidation reaction of the oxidized hair dye, so that the application time can be extended. Without the need for special equipment,
Good hair dyeing power can be obtained with less dye than before, and conventional hair dyeing power can be obtained in a short application time by using a conventional amount of dye.

The hair dye composition of the present invention can provide a uniform hair dyeing power from the hair tip to the root of the hair.
This is presumed to be due to the following reasons. In the hair, the part close to the scalp (root part) is close to 37 ° C due to the influence of body temperature from the scalp, and the hair tip part and the head surface far from the scalp are close to room temperature (20-25 ° C), about 10 ° C or more. Temperature difference may occur. Due to this temperature difference, it was difficult for the conventional hair dye composition to obtain a uniform hair dyeing power from the tip to the root of the hair, but the hair dye composition of the present invention self-heated and caused the composition itself to reach body temperature. This is because the temperature can be set to a nearby temperature, and the root to the hair tip can be dyed at a uniform temperature without being affected by the body temperature. Hereinafter, the present invention will be described in detail.

The heat generation principle used in the hair dye composition of the present invention includes an oxidation-reduction reaction, a dissolution reaction and a neutralization reaction, and the energy released during each reaction serves as a heat source.

In order to utilize each reaction, an environment in which each reaction occurs immediately before application may be created. That is, it is achieved by mixing an oxidizing agent and a reducing agent, an organic solvent and water, or an acid and a base immediately before use, which are stored separately in a multi-drug type. If both the oxidizing agent and the reducing agent or both the acid and the alkali are powders, they can be stored under conditions that allow stable coexistence in the absence of moisture, and can be reacted by dissolving in a dissolving solution at the time of use. .

The reducing agents used in these reactions include thioglycolic acid, cysteine, acetylcysteine and salts thereof, sulfites, pyrosulfites, thiosulfates and the like.

Examples of the oxidizing agent include hydrogen peroxide, urea peroxide, percarbonates, perborates, persulfates, bromates, strontium peroxide, zinc peroxide, barium peroxide and sodium peroxide. No.

Among these, it is particularly preferable to use sodium sulfite and / or sodium pyrosulfite as a reducing agent and hydrogen peroxide as an oxidizing agent in terms of a dyeing effect and a heat generating effect. Further, when one or more selected from ammonium persulfate, sodium persulfate and potassium persulfate are added to this combination, the exothermic effect can be further enhanced.

Examples of the organic solvent include glycerin, polyethylene glycol, propylene glycol, 1,3-butylene glycol, and N-methyl-2-pyrrolidone. From the viewpoint of the exothermic effect, glycerin, polyethylene glycol and N-methyl-2 are used. One or more selected from -pyrrolidone are preferred.

Examples of the base include sodium hydroxide, potassium hydroxide, ammonia, monoethanolamine, triethanolamine and 2-amino-2-methyl-1-propanol. Examples of the acid include hydrochloric acid, phosphoric acid, citric acid, lactic acid, glycolic acid, levulinic acid and the like.

Of these, sodium hydroxide and / or potassium hydroxide as a base and hydrochloric acid as an acid are particularly preferable in view of the exothermic effect.

Among these exothermic reactions, an oxidation-reduction reaction and a dissolution reaction are preferred from the viewpoint of the exothermic effect, and an oxidation-reduction reaction is more preferred from the viewpoint of the sustained exothermic effect.

Since the amount of heat generated differs depending on the substance to be reacted, the amount of heat generation cannot be unconditionally determined. However, it is preferable to mix the medicines so that the heat generation temperature of the mixed drug is in the range of 30 to 45 ° C. If the temperature is lower than 30 ° C, the effect of promoting hair coloring is weak, and 45 ° C
A higher temperature is not preferred because it is too hot and gives discomfort.

When an oxidation-reduction reaction is used, the calorific value depends mainly on the amount of the reducing agent.
When 5.0% by weight is added, the heat generation temperature is preferably 30 to 45 ° C, which is preferable. When a dissolution reaction is used, this temperature is achieved by mixing an agent consisting of an aqueous composition containing a dye or the like and an agent consisting of only an organic solvent in a ratio of usually 1: 0.5 to 2. Is done.

Dichloroparaphenylenediamine, paraaminophenylsulfamic acid, 2,5-diaminopyridine and salts thereof are preferred from the viewpoint of hair dyeing power. The mixing amount of the hair dye composition of the present invention is from 0.01 to 10% by weight at the time of mixing use, and if it is less than 0.01% by weight, a sufficient hair dyeing effect cannot be obtained and 10% by weight. Beyond that, the effect remains unchanged and economic. Further, the content is preferably 0.1% by weight to 5% by weight.
A better hair dyeing effect can be obtained. On the other hand, when it exceeds 5% by weight, the increase in the hair dyeing effect is small.

The mixing amount of the hair dye composition of the present invention is from 0.01 to 10% by weight at the time of mixing use. If the amount is less than 0.01% by weight, sufficient dyeability cannot be obtained, and 10% by weight is not obtained. Beyond that, the effect remains unchanged and economic. Moreover,
The content is preferably 0.1% by weight to 5% by weight, and more excellent dyeing properties can be obtained by adding 0.1% by weight or more. On the other hand, when the content exceeds 5% by weight, the increase in the dyeability is reduced. In addition, components listed in “Quasi-drug raw material standards” (published in June 1991, Yakuji Nippo) can be used as appropriate.

As the direct dye, known dyes such as tar dyes and natural dyes can be used, and one type or two or more types may be used in combination. Among them, nitro dyes, azo dyes,
Nitroso dyes, triphenylmethane dyes, xanthene dyes, quinoline dyes, anthraquinone dyes or indigo dyes are preferable because a good hair dyeing effect is obtained, and these dyes are used when the hair dye composition of the present invention is used in combination. It is best to mix it in a concentration of 0.01 to 10% by weight. 0.01
When the amount is less than 10% by weight, the hair dyeing effect is insufficient. On the other hand, when the amount is more than 10% by weight, not only the hair dyeing power is not improved, but also the dyeing on the scalp and fingers becomes remarkable, which is not desirable.
