Description

TECHNICAL FIELD [0001] The present invention relates to a hair dyeing nanocomposite, a method for producing the same, and a hair dye including the same.

The present invention relates to a hair dyed nanocomposite, a method for producing the same, and a hair dye including the same. More particularly, the present invention relates to a hair dyed nanocomposite having a multi-wall carbon nanotube To a hair dyed nanocomposite capable of improving the durability of dyes and reducing hair damage and skin irritation to dyes, a process for producing the same, and hair dyes containing the same.

The hair dye is classified into a permanent hair dye, a permanent hair dye and a temporary hair dye depending on how long the dyed color lasts. In addition, depending on the mechanism of dyeing, it can be classified into oxidation type hair dyeing agent and non-oxidation type hair dyeing agent. There are permanent hair dyeing agents using oxidative synthetic dyes for oxidative dyeing agents, semi-permanent hair dyeing agents using acid dyes, vegetable hair dyeing agents using vegetable dyes such as henna and chamomile, and metallic hair dyeing agents using mordanting agents containing metal salts .

However, permanent hair dyeing agents using oxidative synthetic dyes are known to cause allergies to humans, and vegetable hair dyeing agents using plant dyes such as henna and chamomile have a limited color tone and are not only dyed in black hair of Asian It is reported to cause allergies to the human body. In addition, acidic dyes have poor bonding strength with the hair and are poor in durability, and there is a problem that the skin is stained on the skin and tinted.

On the other hand, a hair dye having been emulsified or suspended in powdery plant dyes and liquid silicone (silicone), paraffin, vegetable or animal oil, and surfactants has also been proposed. However, such a hair dye has the drawback that it is difficult to obtain a sufficient effect on the color retention which is the highest priority as a hair dye, although stability and usability of the hair dye are improved.

In this regard, Japanese Patent Application Laid-Open No. 2005-139133 discloses a hair dye composition comprising a cationic surfactant, a nonionic surfactant, a higher alcohol and an amino-modified silicone, Characterized in that the composition is used to improve the tackiness to the hair. However, when using the hair dye compositions disclosed herein, in some cases, dripping may occur when applied to hair due to reduced stability of the emulsion.

Further, the hair cosmetic composition according to Japanese Patent Application Laid-Open No. 2004-175748 discloses a hair cosmetic composition for bleaching or dyeing comprising amino-modified silicone, highly polymerized silicone and cationic polymer, and has a high molecular weight polymer component To improve the tactility of the hair treated with the composition and the adhesion to the hair. However, in such a hair cosmetic composition, it is possible to increase the content of the polymer component in order to improve the feeling of damaged hair, but in some cases, it is difficult to uniformly apply the hair to the hair due to the high viscosity, It may not be uniformly bleached or cleaned.

Hair dyeing products contain surfactants, oils such as higher fatty acids, higher alcohols, ester oils and silicone oils, or conditioning agents for cationic polymers to improve the appearance and feel of hair and scalp. In recent years, Although the importance of silicone oil has been gradually increased due to the production of various raw materials that can be appealed to, it visually gives shine to the hair, but the color and color persistence ability is remarkably decreased.

In addition, when dyeing hair using currently available permanent permanent hair dyeing agents, there arises a problem that scalp stimulation (scalp itching) is caused by hydrogen peroxide, ammonia water, monoethanolamine, triethanolamine, surfactant etc. constituting the hair dye And the above-mentioned chemicals are not soluble in water, which is a major cause of environmental pollution.

Japanese Patent Application Laid-Open No. 2005-139133 Japanese Patent Application Laid-Open No. 2004-175748

Hereinafter, the present invention will be described in detail. In the following description of the present invention, a detailed description of known configurations and functions will be omitted.

The terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings and should be construed in accordance with the technical meanings and concepts of the present invention.

The embodiments described in the present specification and the configurations shown in the drawings are preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention and thus various equivalents and modifications Can be.

When the hair is enlarged to a large size, as shown in Fig. 1, there is a layer like a fish scale, which is called a curled hair, and is composed of a hard keratin, and the lower part has a curled 5 to 8 layers. The hair dye is applied to the surface of the hair using the structure of the hair, and a thin vinyl film is overlaid on the surface of the hair. However, such a method has a disadvantage that the hair is shiny but the color is poor .

In addition, in general, the stain agent which is provided in the market is an artificial chemical agent, which is known to cause various acute allergic symptoms including dermatitis, and these chemicals are not well soluble in water, which is a major cause of environmental pollution.

The hair dyes containing the hair dyed nanocomposite according to the present invention can strongly hold the dye on the surface of the hair, so that the hair can be stained for a longer time and hair damage can also be reduced.

The principle of the hair dye including the hair dyed nanocomposite according to the present invention is that the oxygen contained in the multi-walled carbon nanotube combines with the keratin of the hair to capture the dyes, The dyes of hair dyes, including nanocomposites, can be sandwiched between the cuticles to improve their antioxidant and sustainability. In other words, since the binding force between the dye and the hair is excellent, even a small amount of dye can exhibit sufficient dyeing effect.

As a result, the hair dye according to the present invention can reduce the environmental pollution by reducing the amount of the dye, and can be used as a triggering dye that causes dermatitis or various allergies in accordance with decrease in the relative amount of the dye, The fur protection effect can be predicted because the number of cases where the concentration can be used is increased.

In order to achieve the object of the present invention, the present invention can be produced by the following method.

The present invention provides a method for producing a hair dyeing nanocomposite by mixing a dye and a multi-wall carbon nanotube.

Preferably, the mixing ratio of the dye and the multi-wall carbon nanotube is 1: 0.01 to 1: 0.90, and the ratio of the dye to the multi-walled carbon nanotube Multi-wall Carbon Nanotube) according to the number of layers and diameters.

However, when the upper limit of the dye content is exceeded, the multi-wall carbon nanotubes may not have sufficient hydrogen interactions and van der Waals interactions to capture the dye, If the lower limit of the dye content is less than the lower limit of the dye content, sufficient dye can not be supplied to the hair, which makes it impossible to dye the desired color.

The average diameter of the multi-walled carbon nanotube may be 2 to 100 nm and the length may be 100 to 200 μm.

Wherein the dye is selected from the group consisting of p-phenylenediamine, m-phenylenediamine, m-aminophenol, p-aminophenol, o-aminophenol, p-amino- ocresol, m-phenylenediamine, resorcin, And 2,4-diaminophenoxyethanol hydrochloride.

The multi-wall carbon nanotube is a van der Waals interactions in which hydrophobic interactions are caused by oxidation of atmospheres due to defects or oxidation due to weak acids, To produce a hair dyeing nanocomposite.

In other words, multi-wall carbon nanotubes combine with dyes colored in hair to form crosslinks between dyes and hairs, thereby increasing the amount of dye necessary for dyeing Can be optimized.

A hair dye comprising the hair dyed nanocomposite prepared according to the production method of the present invention is provided.

The hair dyed nanocomposite may include 1 to 90 parts by weight based on 100 parts by weight of a hair dye.

When the content of the hair dyeing nanocomposite exceeds the upper limit, it does not have a sufficient viscosity as a dye and thus the hair-releasing property is significantly lowered and the acidity is difficult to control. Thus, hair damage can be further induced. When the content is less than the lower limit, sufficient dye is supplied to the hair It is impossible to dye the desired color and it is not preferable.

The hair dye may be further selected from the group consisting of a hair protecting agent, a chelating agent, a surfactant, a pH adjusting agent, an alkaline agent, a humectant, a thickening agent, an antiseptic, an antioxidant, a bactericide, an anti-inflammatory agent, an antimicrobial agent, But not limited to, one or more components.

In addition, in the method of the present invention, the hair dye may be manufactured in the form of a cream, a liquid, a powder, a jelly or an aerosol, but is not limited thereto.

Hereinafter, the present invention will be described in more detail with reference to Examples. It is to be understood by those skilled in the art that these embodiments are only for describing the present invention in more detail and that the scope of the present invention is not limited by these embodiments in accordance with the gist of the present invention .

< Example  1> Production of hair dyed nanocomposite and hair dye 1

The hair dyed nanocomposite is prepared by mixing the p-phenylenediamine dye and the multi-wall carbon nanotube at a ratio of 1: 0.5 by mass ratio for at least 1 hour.

The hair dyed nanocomposite was mixed with a pH adjusting agent to adjust the pH to 5.5 ~ 8, and 0.8% by mass of the increasing agent was mixed with the dye to prepare a cream type hair dye.

< Example  2> Production of hair dyeing nanocomposite and hair dye 2

The p-amino-ocresol dye was used in the production method of Example 1, and the rest were prepared in the same manner.

< Example  3> Production of hair dyed nanocomposite and hair dye 3

In the production method of Example 1, the resorcinol dye was used, and the rest was prepared in the same manner.

< Example  4> Production of hair dyed nanocomposite and hair dye 4

In the manufacturing method of Example 1, the dye and the multi-wall carbon nanotube were mixed at a mass ratio of 1: 0.01, and the rest were prepared in the same manner.

< Example  5> Production of hair dyed nanocomposite and hair dye 5

In the manufacturing method of Example 1, the dye and the multi-wall carbon nanotube were mixed at a weight ratio of 1: 0.90, and the remainder were made in the same manner.

< Comparative Example  1> Multi-layer wall  Multi-wall carbon Nanotube ) Without mixing

In the manufacturing method of Example 1, the multi-wall carbon nanotubes were not mixed and the rest were manufactured in the same manner.

< Comparative Example  2> With dye Multi-layer wall  Multi-wall carbon Nanotube ) Are different from each other in preparation 1

In the manufacturing method of Example 1, the dye and the multi-wall carbon nanotube were mixed at a weight ratio of 1: 0.005, and the rest were prepared in the same manner.

< Comparative Example  3> Multi-layer wall  Multi-wall carbon Nanotube ) Are different from each other in manufacturing 2

In the manufacturing method of Example 1, the dye and the multi-wall carbon nanotube were mixed at a mass ratio of 1: 1, and the rest were prepared in the same manner.

< Experimental Example  1> Clinical trial: Feeling  And staining consistency

In order to confirm the feeling of use (scalp stimulation) and persistence of dyeing, 20 adult men and 20 adult women were evaluated for feeling of use and persistence of dyeing during application of the hair dye composition.

Each of the above Examples 1 to 5 and Comparative Examples 1 to 5 was applied to four horses, respectively, and allowed to stand for 20 minutes, followed by washing and drying. At this time, the application amounts of the dye were all the same.

The average scores of the agents are shown in Table 1 below. The items were rated on a scale of 10 out of 5 points each for feeling and durability. The feeling of use was evaluated as having less stimulation of the scalp as the evaluation score was higher. Durability persistence was compared with hair color after 15 days and 30 days after dyeing and immediately after dyeing.

The scoring criteria are as follows.

Very good: 5 points

Good: 4 points

Usually: 3 points

Bad: 2 points

Very bad: 1 point

division Feeling Dyeing persistence Immediately after dyeing 15th 30 days Example 1 4.8 4.9 4.4 4.2 Example 2 4.6 4.8 4.4 4.0 Example 3 4.8 4.8 4.4 4.1 Example 4 4.5 4.7 4.2 4.0 Example 5 4.6 4.9 4.4 4.2 Comparative Example 1 2.8 3.5 2.2 1.7 Comparative Example 2 3.4 3.9 3.4 2.6 Comparative Example 3 3.8 3.6 3.5 3.0

As a result of evaluating feeling, the hair dye prepared by <Examples 1 to 5> was produced by mixing the multi-wall carbon nanotube with the dye in an optimal ratio, And it showed excellent feeling because it had little stimulation of scalp and little allergic reaction. In addition, it was confirmed that, even in the case of 15 days and 30 days of dyeing persistence, the color feeling immediately after dyeing was maintained almost unchanged.

On the other hand, the hair dye prepared by <Comparative Example 1> on the feeling of use was continuously performed while the scalp stimulation such as stigma and heat sensation proceeded. The hair dye prepared at a ratio of the multi-wall carbon nanotube as in Comparative Example 2 was less than that of the present invention. However, when the scalp was applied, It was confirmed that feeling was not good when coming up.

<Comparative Example 3> The hair dye prepared by exceeding the ratio of the multi-wall carbon nanotube in the present invention was less stained at the time of applying the scalp, but the amount of the dye was insufficient, Was not properly expressed.

In Comparative Example 1, which was dyed in the same amount in the dyeing durability, it was found that the color of the hair was not expressed properly as compared with Examples 1 to 5, and especially after 15 days and 30 days, It was confirmed that the color was not maintained due to a sudden drop. <Comparative Example 2> was found to exhibit a certain degree of color tone immediately after dyeing, but it was found to be insufficient in terms of continuity. <Comparative Example 3> was found to maintain the durability to some extent but not to express color tone immediately after dyeing.

Therefore, the hair dye according to the present invention can minimize the irritation of the scalp during dyeing by preparing the dye and the multi-wall carbon nanotube in an optimized ratio, and can provide a hair dye necessary for hair dyeing Can be minimized, and an excellent persistence can be provided.

<Example 1-2> Image inspection of the hair surface

(a) the hair of a control group that is not dyed, (b) the hair of the comparative group stained with the general dye of Comparative Example 1, and (C) the hair of the experimental group stained with the hair dye of Example 1 Immediately after the hair was dyed and washed for 30 minutes, each hair was individually collected and observed using a laser scanning confocal microscope (CLSM) (Figs. 2 to 4).

In FIG. 2 (b), it can be seen that the dyestuff dye does not bind between the cuticle layers of the hair but simply stays on the surface. In such a dyed hair, the color tone may be expressed to some extent immediately after dyeing There is a problem in that the dye is washed in water after the washing, and the consistency is remarkably lowered. (C) can see the cuticle layer at roughly the same level as unhardened hair, confirming that the dyes are properly bonded between the layers.

The state in which the dyes are bonded is shown in Fig. 3 in detail. That is, the oxygen contained in the multi-wall carbon nanotube combines with keratin in the hair to capture the dyes, and the dye can be sandwiched between the cuticles to improve the antioxidant and persistence.

4, after washing the dyed hair for 30 minutes, it can be seen that in the case of (b), almost no dye remains and only a very small amount of dye remains between the cuticle layers, and the dye in (C) And it was confirmed that it was maintained at almost the same level as the dyeing hair.

As described above, preferred embodiments of the present invention have been disclosed in the present specification and drawings, and although specific terms have been used, they have been used only in a general sense to easily describe the technical contents of the present invention and to facilitate understanding of the invention , And are not intended to limit the scope of the present invention.

It is to be understood by those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
