[0001] Remover composition for mordant hair colorants [

The present invention relates to a remover composition for mordant hair detergent composition, which contains an antioxidant, a chelating agent and a pH adjusting agent, so that hair color dyed with a mordant hair dye or dyeing agent applied to the scalp or skin can be effectively applied without damaging hair or skin irritation And more particularly to a remover composition which can be removed.

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 .

The mordant salt is a medicine which produces a colored compound which is insoluble (insoluble) when it is dyed with a dye (mordant dye) having no dyeability (dyeing dye) against the dye to be dyed, . In other words, it refers to an operation of treating a dye that is not directly dyeable to the target dyed with an agent that completes dyeing by connecting it to the dyed material because of lack of affinity for the dyed material.

Conventional metallic hair dyeing agents contain metallic compounds such as iron, copper, zinc, silver, and bismuth as mordants, and contain metallic compounds such as gallic acid, gallic acid esters, tannic acid and esters thereof or pyrogallol as coloring agents, And dyeing by the reaction of the metal ion and the coloring agent. Since the hair dye has no primary irritation or sensitivity to the human body, it is a useful hair dye for people who cause an allergic reaction to the oxidized hair dye.

In the ordinary mordanting reaction, the mordanting is classified into pre-mordanting, simultaneous mordanting and post-mordanting. Herein, the term mordenite refers to a method of treating a dye after treatment with a mordant, and a method of treating a mordant followed by treatment of a mordant and dye simultaneously with mordanting. Currently, hair dyeing agents commercialized using such a mushing mechanism are seldom found, but in the market, it is known that they are formed by postmeal dyeing.

Such mushroom hair dyeing agents are difficult to change their hair color by using other hair dyeing agents once they are dyed, and when they are stained on scalp or skin, they are not easily erased. When using ordinary shampoo or soap, There is a disadvantage that it can not be removed.

In order to remove color from hair dyed with a permanent hair dye, bleaching agents are generally used, and there are commercially available remover for acid hair dye to remove color stained with acid hair dye. However, it is difficult to remove the color stained with the mordant hair dye using such a product. When decolorizing agents are used, they cause a lot of hair damage. Even if a remover for a commercial acid hair dyeing agent is used, it is not possible to remove the contamination on the scalp or the skin with a mild salt hair remover. In other words, it is difficult to find a commercially available remover for mushroom hair remover.

The inventors of the present invention have studied a method for effectively removing dyes stained with hair with a mordant hair dye and dyed on the scalp or skin as a result of dyeing. As a result, in order to remove metals from the mordant hair dye, only a chelating agent or only a pH adjusting agent It was confirmed that the mordant color of the mordant hair dye can not be effectively removed by adjusting the pH alone, and that the dye can be effectively removed by using an antioxidant and a chelating agent and a pH adjusting agent.

Accordingly, an object of the present invention is to provide a remover composition which effectively removes dyes dyed with a mordant hair dye or dyed with the skin without damaging the hair or skin irritation.

In order to achieve the above object, the present invention provides a remover composition for a mousse hair dye containing an antioxidant.

[Test Example 1] Denitration power

In order to test the demineralization power, hair that had been stained with a commercially available mush salt was first prepared. The length of the hair was 23cm, and the amount of hair was twice as much as that of the hair, and the hair was allowed to stand for 20 minutes. After 20 minutes, one agent and the same amount of the two agents were evenly applied on the substrate and left for another 20 minutes. The mushroom hair dye (Dongsung Pharmaceutical herbal color cream) was used in the experiment. The standard hair contains 20-30% of black hair, and the L * value is 22.54. After 20 minutes, the hair was washed with flowing water for 1 minute and then the hair was dried using a hair dryer. The dried hair was measured for color using a color difference meter (model: Hunterlab Labscan XE). The measured L * (before treatment) was taken as the initial value. The dyed hair was immersed in the solution shown in the above Examples and Comparative Examples, and then stirred for 20 minutes using a stirrer. The amount of the solution was 20 times the hair weight and the stirrer was set to 200 rpm. After the stirring was completed, the hair was washed with running water for 1 minute, dried by drying, and the color was measured by a colorimeter to determine L * (after treatment). The degree of color removal was compared using the difference in L * values before and after the remover treatment. Here, the L * value is a numerical value indicating the brightness, and the larger the L * value, the brighter the color. Therefore, as the difference in brightness before and after dyeing, ΔL *, is larger, it means that the color is lost more. The results are shown in Table 2 below.

Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Before processing L 11.31 11.24 11.67 11.24 11.89 11.37 11.89 After processing L 21.22 20.17 22.23 11.74 13.44 20.98 13.44 DELTA L ^* 9.91 8.93 10.56 0.50 1.55 9.61 1.55

As shown in Table 2, Examples 1 to 3 containing an antioxidant showed much better demineralization power in hair than Comparative Example 1, which did not contain an antioxidant. On the other hand, in Example 2 which does not contain a chelating agent, it is understood that the demineralization power is not significantly lowered as compared with Examples 1 and 3. From this, it can be seen that the chelating agent in the remover composition for mush salt hair formulations of the present invention is not so much affected as compared with the antioxidant.

Comparing Examples 1 to 3 and Comparative Example 2 according to the present invention, it can be seen that when the pH is less than 4, the demineralization force is significantly lowered.

In addition, when Example 1 and Example 3 using a solvent are compared, it can be seen that Example 3 using a solvent is slightly improved in demineralization power, but is further improved.

[Test Example 2] Skin irritation degree confirmation test

Subjects were selected to test skin irritation. Tests were conducted on healthy adults and those holding psoriasis, acne, eczema, other skin diseases, pregnancy, lactation or contraception, antihistamines, etc. were excluded . A total of 12 subjects were selected from 10 male and 2 female subjects. The subjects were dropped into a hilltop chamber in an amount of about 450 ml / 25 mm, and then adhered to the skin. The evaluation was made by visual evaluation and instrument measurement. The visual evaluation was carried out one hour after removal of the patch and according to the method described in the CTFA Guideline. Instrumentation was measured before and 1 hour after removal of the patches using a Vapometer (TEWL), a pH meter (pH meter) pH). When measuring pH, it is affected by the amount of water applied to the surface of the skin. Therefore, it was normalized to 20 μl during measurement (pH of DW used in the measurement was 7.3).

Statistical analysis was performed by Paired T-test (instrumental) or Mann-Whitney Test (minitab). The results are shown in Table 3 below.
