Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emulsion composition for decolorizing or dyeing oxidized hair containing ammonia, and a method for decolorizing or dyeing hair using the emulsified composition to suppress the irritating odor of ammonia.

[0002]

2. Description of the Related Art Oxidizing two-part bleaching agents and hair dyes are
Dye alone or in addition to alkali
And an oxidizing agent such as hydrogen peroxide as a main component.
The above two agents are mixed at the time of use.
The hair is bleached or dyed.
For hair dyes and bleaching agents, there are two types, one type and three types
is there. One-part formula for hair dye contains only alkaline agent and dye
It does not contain an oxidizing agent and oxidizes naturally in the air
Things. The three-part formula for hair dye and decolorizing agent
In addition to persulfate (oxidizing agent) and carbonate (alkali)
Type), ie, alkaline agent
Hydrogen peroxide alone or with an agent containing an alkaline agent and a dye
Immediately before treatment
It is used by mixing.

The alkaline agents contained in the one-pack, two-pack and three-pack systems include ammonia, ethanolamine,
Although carbonates and the like can be mentioned, air ethanolamine has a strong residual property and has drawbacks such as hair damage and skin irritation, and a carbonate has a weak effect of enhancing the bleaching power and hair dyeing power by hydrogen peroxide. Therefore, it has a drawback that the color tone of the hair cannot be made too light. Ammonia, on the other hand, does not remain on the hair or scalp, and is highly safe, with no risk of causing hair damage or skin irritation. It is most commonly used because it has the property of making it strong enough. However, Ammonnia has a peculiar irritating odor at the time of treatment, especially when increasing the lightness of hair, because it needs to be blended in a large amount, so it has a strong irritating odor and gives discomfort. .

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to an ammonia-containing decolorizing agent which is excellent in safety with less damage to hair and skin irritation and irritation and which has no or reduced irritating odor of ammonia. An object of the present invention is to provide an emulsified composition for hair and hair dyes, and a method for bleaching or dyeing hair using the emulsified composition.

[0005]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, in the emulsified composition of a hair dye or a bleaching agent containing ammonia as a main component, an irritating odor of ammonia was found. The present inventors have found that the problem of suppression of the problem can be solved by reducing the emulsified particle diameter, and reached the present invention. That is, in the present invention, the average emulsified particle diameter of an emulsified composition containing ammonia for hair coloring or hair bleaching (hereinafter, referred to as a first agent) is usually about 50 μm. By reducing the size of the emulsified particles,
It has been found that when the thickness is 3 μm or less, particularly 10 μm or less, the irritating odor of ammonia can be remarkably suppressed.

[0006] The aforementioned "irritating odor of ammonia is remarkably suppressed.
"Does" means that in the emulsified composition of the first agent,
Irritating odor increases as the amount of ammonia increases.
However, reducing the average emulsified particle size, especially 10
μm or less, containing conventionally known ammonia.
The same amount of ammonia was blended compared to the emulsion composition having
In this case, the effect of suppressing the irritating odor of ammonia is remarkably large.
It means big. Examples of the first agent of the present invention include:
For example, a commercially available ammonia-containing hair bleaching or hair coloring agent
Emulsified composition for use in the emulsion composition, and the emulsified composition contains 28%
Ammonia water is about 3 to 15% by weight, usually 6 to 8%
% Is used.

The present invention further provides a hair bleaching method or a hair dyeing method using the above-mentioned emulsion composition containing ammonia. Further, the present invention also provides a hair bleaching method or a hair dyeing method using an oxidizing type bleaching or hair coloring agent using an emulsion composition containing ammonia and a oxidizing agent having similar viscosities. In this case, the viscosity of the two agents is 10,000 to 60,000 cp.
It is preferred to be about s.

Hereinafter, embodiments of the present invention will be described, and the present invention will be described in detail.

BEST MODE FOR CARRYING OUT THE INVENTION The first agent of the hair dye and bleaching agent of the present invention comprises at least (1) ammonia, (2) a surfactant, (3) a solvent (water), and (4) an emulsified constituent ( Oil, silicone, etc.).

In the first agent of the present invention, the effect of suppressing the irritating odor of the ammonia increases as the average emulsified particle diameter decreases, and as described above, the average emulsified particle diameter becomes 13 μm.
If it is less than about 10 μm, the effect of suppressing the irritating odor of ammonia is sufficiently produced.
By setting the particle size to μm or less, more preferably in the order of nm, the effect of suppressing the irritating odor of ammonia is further increased, but it is usually difficult to reduce the average emulsified particle diameter to 5 nm or less. Therefore, in the first agent of the present invention, the average emulsified particle diameter is about 13 μm to 5 nm, preferably 1 μm.
0 μm to 5 nm, more preferably 1 μm or less, practically about 1 μm to 5 nm is used. In addition, as the amount of ammonia in the first agent increases, the irritating odor of ammonia is suppressed. It is preferable to reduce the average emulsified particle diameter. The control of the average emulsified particle diameter is performed, for example, by appropriately changing at least one or two or more of the requirements such as the composition of the components constituting the first agent, the order of mixing, and the degree of stirring. be able to. In the present invention, the suppression of the irritating odor of ammonia means that the practitioner and the subject do not feel the irritating odor of ammonia when performing the treatment of dyeing or bleaching hair using the first agent of the present invention, or It has a slight ammonia smell. In addition,

Similarly to the agent, from the viewpoint of suppressing the smell of ammonia, the effect becomes more remarkable as the emulsified particle diameter is reduced.

It is preferable that the first agent and the second agent have the same physical properties, particularly the same viscosity. It is particularly preferable that the first agent and the second agent are of the same dosage form, have the same viscosity, and have a viscosity that does not cause dripping on the hair. When the first agent and the second agent having the above-mentioned properties are used, not only is it easy to mix the two agents, but also the viscosity is always constant even if the two agents are mixed in any combination and / or in any ratio. Thus, problems such as the dripping of the emulsified composition or the difficulty in performing the treatment due to being too hard can be solved. Therefore, at the time of treatment, the practitioner can easily mix the first agent and the second agent at a free ratio, and can freely change the lightness and color tone of the hair.

Even if there is, as described above, the practitioner can easily mix the first agent and the second agent at a free ratio, and if it is possible to freely change the lightness and color tone of the hair, The viscosities of the first agent and the second agent are substantially the same.

In the embodiment of the present invention, a two-part system using a first agent and a second agent for a hair dye and a bleaching agent has been described. When an emulsified composition containing ammonia is used, the smell of ammonia can be suppressed by reducing the emulsified particle size of the emulsified composition. In particular, also in the three-part system, when the agent containing the oxidizing agent is an emulsified composition, the effect of suppressing the smell of ammonia can be enhanced by reducing the emulsified particle size of the agent.

According to the present invention, the hair can be decolorized or dyed using the above-described emulsion composition containing ammonia. In this case, in the case of the one-drug type, one treatment is taken in a cup, and in the case of the two-drug type and the three-drug type, the first agent containing ammonia and the second agent containing the oxidizing agent are usually used for one treatment. The same amount of the agent is placed in a cup, and in the case of a three-agent system, the powder composition of the third agent is further added, mixed with a brush, and the treatment is performed in a usual manner.

As a treatment method for further improving the effect of the present invention, the physical properties of the first agent containing ammonia and the second agent containing the oxidizing agent, particularly, in the case of the two-drug type and the three-drug type, particularly It is preferable to provide the same treatment for the viscosity. By using the same viscosity as described above, not only the 10% and the second agent can be easily and uniformly made at the time of mixing, but also the 10% and the 2nd agent at the time of treatment. The mixing ratio can be set arbitrarily, and as a result, an arbitrary color tone can be obtained. In this case, the viscosity of the emulsion composition is 1
It is preferably from 000 to 60,000 cps.
