Description

{A hair or scalp cleansing composition containing tannic acid, water-soluble metal salt}

The present invention relates to a wash-off type scalp or hair cleaning composition that has a hair cleaning effect and prevents fading of dyed hair or adding color to the hair.

In the conventional method of dyeing keratin fibers, it is classified into temporary hair dyeing agents, semi-permanent hair dyeing agents, and permanent hair dyeing agents according to the persistence of the hair dyeing effect. Among them, the permanent hair dye with the best persistence is also referred to as an oxidizing hair dye. In the case of temporary hair dyes and acid hair dyes, which are semi-permanent hair dyes, the duration is short and the water fade is severe. The majority of hair dyes in the market are permanent hair dyes using oxidation polymerization. Oxidative hair dyes are the most widely used class of hair dyes because low molecular weight oxidizing dyes or pigments cause oxidation polymerization in the hair to form pigments, which can obtain various colors and have excellent hair dyeing power. . Such an oxidation-type hair dye composition is usually composed of a first agent including an oxidizing dye and an alkalizing agent typified by an aromatic amino compound such as paraphenylenediamine, and a second agent including hydrogen peroxide as an oxidizing agent. When applied to actual hair, such an oxidized permanent hair dye has the advantage of high hair dyeing power and good color lasting power because a large dye molecule is condensed and polymerized inside the hair by applying a mixture of the first agent and the second agent. The purpose of using this hair dye is to dye the hair as completely as possible and maintain the hair dye effect for a long time.

However, in the case of oxidized hair dyes, there is a disadvantage of irritation to the skin by allergies, alkalizing agents, hydrogen peroxide, etc. by oxidizing dyes, and disulfide bonds (SS) in the hair are destroyed in the process of decoloring the hair by the action of the oxidizing agent. Compared to healthy hair due to severe damage, the touch of dyed hair deteriorates and the gloss of the hair decreases. In addition, currently commercially available hair dyes, including oxidized hair dyes, lose water when shampooing the first three or more times after dyeing, and in particular, some of the oxidation dyes used for dyeing do not react completely and remain in the hair for a long time. As the flow increases, there may be a case of continuous water drainage due to oxidation and color development on the surface, and the water drainage phenomenon in damaged hair after dyeing becomes more pronounced. There is a problem in that the degree of discoloration is considerable due to this water dropout phenomenon, and thus a difference in the initially targeted color occurs.

On the other hand, as other hair dyeing agents, there is a metal plant mixed hair dye comprising a vegetable natural dye and a mordant containing a metal salt. Mordant is a method of fixing or generating a dye through an appropriate mordant when the dye is not directly dyed on the fiber.The dyeing agent for vegetable natural dyes containing metal salts does not use aromatic amino compounds such as paraphenylenediamine, which are used in oxidizing hair dyes. The advantage is that there is no allergic reaction and there is little harm to the human body.

However, in the case of metal plant-mixed hair dyes, there is a disadvantage in that the retention period of the dyed color is shorter than that of oxidation-type hair dyes, and during dyeing, the first and second agents are reapplied to the hair with a time difference, so that the dyeing procedure is very long. There is a long discomfort. In addition, iron salts in shampoo compositions, hair shampoos, conditioners, tonics, creams, styling gels, and mousses are also provided with organic compounds such as catechol, pyrogallol, gallic acid, and tannic acid esters. This is a pre-morning method in which the hair is treated with a metal mordant first, and has a disadvantage in that the color fastness decreases compared to the post-morbid method.

Accordingly, as a result of researching to solve the above problems, the present inventors have tried to provide a product that is easy to use and can darken the color of hair without harm to the human body.

In order to solve the above problems, the inventors of the present invention intend to provide a product capable of dyeing or blackening hair or preventing, improving or alleviating color loss of dyed hair by using a shampoo composition and a hair conditioner composition.

The inventors of the present invention confirmed that tannic acid exhibits a dark color by coordinating it with a metal salt, and that the water-soluble metal salt serves to strengthen the binding of the dye by performing mordant bonding with tannic acid and hair, and completed the present invention.

Hereinafter, the present invention will be described in more detail.

One embodiment of the present invention provides a product for dyeing or blackening hair and/or a product for cleaning dyed hair that improves color loss of dyed hair. Another embodiment of the present invention provides a method of dyeing the hair by washing the hair with a first agent and a second agent and/or a method of improving the drainage of dyed hair. Considering that it is generally difficult to color whitened hair in general, when dyeing whitened hair, the color of the hair will quickly disappear or it is not easy to apply color.

As used herein, "dyeing" not only includes the process of applying color to natural hair, but also includes the process of applying color to discolored hair. As used herein, "blackening" refers to darkening of whitened hair, and refers to a state in which whitened hair is colored. "Product" of the present specification may be understood in the same sense as a set of compositions including several compositions, and may be used in place of a kit. In the present specification, "cleaning" may refer to a process in which a product for hair is treated on the hair and then rinsed cleanly.

The content of tannic acid may be included in 0.0001 to 5% by weight based on the total weight of the composition, preferably 0.01 to 4% by weight, more preferably 0.01 to 2% by weight. When the content is less than 0.0001% by weight, the effect of adding color to the hair is poor, and when it exceeds 5% by weight, precipitation occurs due to differences in solubility and stability in the formulation.

In the present invention, "water-soluble metal salt" refers to a divalent or trivalent water-soluble metal salt. Metal salts used as mordants are usually 4 or 6 coordination metal ions, and 4 coordination metal ions include nickel ions (Zn ^{2 +} ) and zinc ions (Zn ^{2 +} ), and 6 coordination metal ions include ferrous iron.

When mordating with such metal ions, metal ions bind to dye molecules and fibers in various directions in a very complex form, and dye molecules combine these metal ions with other molecules as a medium to show electron transfer, resulting in deep color tone. At the same time, the stability increases. In addition, a resonance phenomenon accompanying electrons occurs, and depending on the number and intensity, different shades overlap, so the color tone after mording becomes dull.In particular, mordants caused by iron ions have a large overlap of shades, so when the concentration increases, the color tone becomes black. do.

Experimental example 1: Evaluation of the effect of adding color to the hair

In order to test the effect of adding color to hair, a standard white hair was weighed at 1.0 g, and the shampoo composition prepared in Example 1 was applied in an amount of 1/10 weight relative to the weight of the hair tress, and then handed for 1 minute. After rubbing massage and washing with running water for 1 minute, the conditioner composition prepared in Example 2 was applied in an amount of 1/10 weight of the weight of the hair tress, then rubbed by hand for 1 minute and then washed with running water. After washing for a minute, it was dried.

After repeating the above process 7, 14, 21, 28 times, the color was observed, and the result was taken as a photograph and shown in FIG. 1.

The color difference was quantified by measuring the color change of the hair using a color difference meter (KONICA MINOLTA, CHOROMA METER CR-400) every 7, 14, 21, and 28 washings based on the color of the hair tress immediately after the initial dyeing. The *L value representing the shade of the color (the larger the number, the brighter) was compared and evaluated.

Experimental example 2

Experiments were performed in the same manner as in Experimental Example 1, but after washing with the shampoo composition prepared in Example 1, the conditioner composition prepared in Example 3 was applied, then rubbed by hand for 1 minute and massaged in running water for 1 minute. After washing, it was dried. The results are shown in Table 3. Table 3 is a result of comparing the difference in hair dyeing power according to the water-soluble metal salt.

(Example 1 + Example 3) 72.43 60.12 57.39 53.04 48.20 Control (*L)
(Comparative Example 1 + Comparative Example 2) 70.39 70.07 68.77 69.66 68.59

As shown in the table above, it can be confirmed that the color of the hair is darkened by repeated washing by using a tannic acid-containing shampoo and a metal salt-containing conditioner composition together.

When the hair treatment was washed using a shampoo composition (Comparative Example 1) and a conditioner composition (Comparative Example 2) that did not contain tannic acid and water-soluble metal salts, it was confirmed that no color change occurred.

In the comparison between Experimental Example 1 and Experimental Example 2, there may be a difference in dyeing power depending on the water-soluble metal salt, and it can be seen that when ferrous sulfate was used, the color was added more darkly than that of ferric chloride. .

Experimental example 3: Cationic Polymer by Tannic acid Evaluation of the effect of increasing hair adsorption

To test the effect of increasing the hair adsorption power of tannic acid by a cationic polymer, 1.0 g of standard white wool was immersed in an aqueous solution consisting of the following composition for 10 minutes, washed with running water for 1 minute, and then a 1% aqueous solution of iron sulfate Was treated in an amount of 1/10 weight based on the weight of the hair tress, washed for 1 minute in running water, and then dried. The results are shown in Table 4.

Tannic acid (% by weight) 1.0 1.0 1.0 Polyquaternium-10 (% by weight) 0 0.5 1.0 FeSO ₄ (% by weight) 1.0 1.0 1.0 Dyeing power (△L) 3.38 3.91 4.10

As shown in the above table, it can be seen that as the cationic polymer is added, the adsorption power of tannic acid to the hair increases, thereby increasing the residual rate, thereby increasing the dyeing power.

Experimental example 4: of dyed hair Dripping Prevention effect evaluation

In order to test the anti-draining effect of dyed hair, standard white hair was dyed according to the usage and dosage of the hair dye using a commercially available two-agent type oxidative condensation permanent hair dye with a weight of 1.0 g. Thereafter, the shampoo composition prepared in Example 1 was applied in an amount of 1/10 weight relative to the weight of the dyed hair tress, rubbed by hand for 1 minute, and washed for 1 minute in running water, and then Example 2 The conditioner composition prepared in was applied in an amount of 1/10 weight relative to the weight of the dyed hair tress, rubbed by hand for 1 minute, massaged, washed with running water for 1 minute, and dried.

The color difference was quantified by measuring the color change of hair using a color difference meter (KONICA MINOLTA, CHOROMA METER CR-400) every 7 and 14 washings based on the color of the hair tress immediately after the initial dyeing. (Delta) E value was calculated and evaluated for comparison.

The color of the standard white hair was used as a control, and the color difference between the sample treated by the above experimental method and the control group was calculated using Equation 1 below, and the results are shown in Table 5.

[Equation 1]

△E: Color difference

L: Bright and dark, the larger the value, the brighter (0-100)

a: Green to Red, positive value indicates red color, negative value indicates green color. The larger the absolute value, the stronger the color.

b: Blue to Yellow, if it has a positive value, yellow is expressed, and if it has a negative value, blue is expressed. The larger the absolute value, the stronger the color.

Experimental example 5

Experiments were conducted in the same manner as in Experimental Example 4, but after washing with the shampoo composition prepared in Comparative Example 1, the conditioner composition prepared in Comparative Example 2 was applied and massaged by hand for 1 minute, followed by flowing water for 1 minute. After washing, it was dried. The results are shown in Table 5.

Anti-dye staining effect using tannic acid and water-soluble metal salts division Control 7 times 14 times Experimental Example 4 (ΔE)
(Example 1 + Example 2) Control 2.53 3.89 Experimental Example 5 (ΔE)
(Comparative Example 1 + Comparative Example 2) Control 3.72 5.05

As shown in the above table, when the composition to which the tannic acid/metal salt is applied by repeated washing is used, the color change of the hair is less than that of the case where the general shampoo/conditioner composition is used, so that water loss is prevented.
