In general, the dyeing agent is divided into a permanent oxidative hair dye and a semi-permanent acid hair dye of the coating color. Hair loss scalp and problematic scalp are on the rise due to the chemical treatment of modern people, that is, perme staining and stress. Therefore, now is the time to develop a hair dye that uses the value of natural dyes that can heal scalp and hair problems as well as beautify the concept of dyeing with white hair or change color of hair. In particular, if the hair damage and scalp trouble are severe due to repeated dyeing, it is necessary to induce the hair and the scalp to be healthy by using natural hair dyes because chemical damage occurs again.

However, since the conventional hair dye has a simple role of blackening or giving color to white hair, it was not possible to expect an effect that could be healthy for the scalp and hair. Conventionally, natural hair dyes made from henna plant leaves have been developed, but natural henna has only an orange color component, and when it is desired to dye dark hair to achieve a dark color, PPD (paraphenylenediamine) must be added. In addition, even if the hair is a natural dye, some components are only natural components, and a method of mixing ammonia components and hydrogen peroxide as an alkaline oxidation hair dye is widely used.

Conventional oxidative synthetic hair dyes have a problem of causing scalp hair as a phenomenon in which hair damage and scalp swell because the hair is opened with a pH12 alkali and cut into the cortex.

Accordingly, there is a need to develop a natural hair dye for realizing natural colors without damaging the hair while using natural ingredients as the main raw material.

For example, the medicinal plant extract may be prepared in powder form by additional processes such as distillation under reduced pressure and freeze drying or spray drying.

Hereinafter, a description will be given of a natural hair dye composition comprising a lacquer extract or a hawthorn branch extract of the present invention.

The natural hair dye composition of the present invention includes a dye comprising at least one selected from Rhus verniciflua Stokes extract and Hovenia dulcis branch extract; And mordants including sodium bicarbonate and alum.

The lacquer extract is preferably an extract of the lacquer neck.

The hair natural dye composition is characterized in that it exhibits a yellow reflective (reflect).

It is preferable to use young branches of 3 years old or younger, and more preferably, young branches of 1 year old or younger.

The hut tree extract is preferably mixed with 10 to 30 parts by weight, more preferably 15 to 25 parts by weight with respect to 100 parts by weight of lacquer extract. Accordingly, not only a natural yellow color can be realized, but the fastness to cleaning can be maximized.

As a yellow dye, medicinal plant extracts such as gardenia, turmeric, turmeric, safflower, and marigold can be additionally mixed and used. However, when these are used, lacquer extract or hut branch extract is used alone, or lacquer extract and hut tree Compared to using a mixture of extracts, the color is relatively unnatural to apply to natural hair, and the wash fastness may deteriorate.

The color of natural hair is mixed with three primary colors of yellow, red, and blue to create an achromatic color, and is classified into 1 to 10 stages from black to very bright golden depending on the brightness, and it is set as an international numbering system and used worldwide.

In some cases, the hair natural dye composition of the present invention is a golden color that is the seventh stage from brown, which is the fourth stage of the brightness of natural hair color, by further mixing the above-mentioned dye, that is, the yellow-based dye and the blue-based natural dye. Brightness can be adjusted with (blond).

Specifically, the dye showing brown, which is the fourth step, is preferably prepared by mixing blue-based dyes 230 to 270 parts by weight, and red-based dyes 130 to 170 parts by weight with respect to 100 parts by weight of the yellow dye, and most preferably For example, 250 parts by weight of the blue dye and 150 parts by weight of the red dye may be mixed with respect to 100 parts by weight of the yellow dye.

The dye that exhibits the brown color of the seventh step is preferably prepared by mixing 37 to 43 parts by weight of the blue dye and 57 to 63 parts by weight of the red dye, and most preferably yellow, based on 100 parts by weight of the yellow dye. 40 parts by weight of the blue dye and 60 parts by weight of the red dye can be mixed with respect to 100 parts by weight of the dye.

It is preferable that the yellow-based dye is a mixture of sumac extract, extract of hawthorn branch, extract of sumac and hawthorn branch.

The blue-based natural dye may use one or more extracts selected from indigo, logwood, cloves, and new trees, and the red-based natural dye may use one or more extracts selected from balsam, henna, puppet, safflower, purple, and pine wood. have.

The mordant acts to develop a natural dye to the hair and to make the colored dye in the hair insoluble compound insoluble in water and to develop color, thus assisting color development, dyeing the dye on the hair and improving fastness It is used to order.

The medium and alum contained in the mordant are natural mordants and are characterized by being harmless to the human body.

Sodium bicarbonate is sodium hydrogen carbonate (NaHCO), and is called baking soda, sodium bicarbonate, and sodium bicarbonate. Sodium bicarbonate is weakly basic and can cure the flu and cold, alkalize the body, and prevent disease. It can keep the skin healthy and clean, it is also used for a variety of cosmetic purposes, and it is also a compound in which our kidneys are naturally produced in small quantities.

Alum is a double salt produced by sulfates of aluminum sulfate and monovalent metals. As monovalent metals, alkali metals other than lithium, potassium, and ammonium are used. Double salt refers to a salt in which two or more types of salts are combined, and ions belonging to the salts exist as independent ions without forming multiatomic ions such as complex ions. Alum is also known as alum and has the general formula MAl (SO ₄ ) ₂ · 12H ₂ O or M ₂ SO ₄ · Al ₂ (SO ₄ ) ₃ · 24H ₂ O. M is a monovalent metal. Potassium alumina (KAl (SO ₄ ) ₂ · 12H ₂ O), ammonium alum ((NH ₄ ) Al (SO ₄ ) ₂ · 12H ₂ O), etc. may be present depending on what monovalent metal ion it contains. .

Such alum is known as a component that has a cold, tasteful, salty, non-toxic, antibacterial, detoxifying, sterilizing, and astringent action.

The brightness and color saturation of the color may vary depending on the amount of the mordant.

Preferably, the mordant is used in an amount of 3 to 7 parts by weight based on 100 parts by weight of the dye.

It is preferred to further include an auxiliary mordant in the mordant.

The auxiliary mordant may be salt, chitosan, sugar, coffee, black tea, and the like.

It is preferable that the salt is a sun salt, and if refined salt is used, there is no mineral component such as magnesium, iron, and sodium, so it cannot function as a mordant. Salt causes agglomeration during natural dyeing, dyes are well adsorbed on the hair, and the dynamics help the hair to be uniformly dyed, and water drainage can also be reduced.

Since the chitosan contains an amine group capable of binding with a natural dye, it is dyeable because cationic groups are introduced into various types of anionic hair.

When the dye is applied, the sugar may well bind to the hair and serve to adsorb.

The coffee and tea may contain a tannin component, and may function to dye well.

It is preferred that the hair natural dye composition further comprises a viscosity modifier.

The viscous modifier may use dextrin, potato starch, guar gum, glycerin, cottonseed oil, wheat starch, bentonite, and the like.

By using a viscosity modifier, the natural hair dye composition can be easily applied to the hair.

First, lacquer extract and Hut  A dye is prepared by preparing at least one selected from eggplant extracts (step a).

It is preferable to extract the sumac extract or hut tree branch extract with water, alcohol having 1 to 4 carbon atoms, or a mixed solvent thereof, more preferably hot water extraction.

The dye may be a dye for dyeing yellow reflection.

It is preferable to use the hut tree branch, the young branch of the hut tree.

The hut tree extract is preferably mixed with 10 to 30 parts by weight, more preferably 15 to 25 parts by weight with respect to 100 parts by weight of lacquer extract. Accordingly, not only a natural yellow color can be realized, but the fastness to cleaning can be maximized.

As a yellow dye, medicinal plant extracts such as gardenia, turmeric, turmeric, safflower, and marigold can be additionally mixed and used.

In some cases, the hair natural dye composition of the present invention is a golden color that is the seventh stage from brown, which is the fourth stage of the brightness of natural hair color, by further mixing the above-mentioned dye, that is, the yellow-based dye and the blue-based natural dye. Brightness can be adjusted with (blond).

The blue-based natural dye may use one or more extracts selected from indigo, logwood, cloves, and new trees, and the red-based natural dye may use one or more extracts selected from balsam, henna, puppet, safflower, purple, and pine wood. have.

Next, to the dye baking soda ( sodium bicarbonate ) And Alum  A dye containing a mordant is prepared by mixing the mordant containing (Step b).

When comparing the hair dyed according to Example 5 and the hair dyed according to Comparative Example 4, the hair of Example 5 was found to exhibit natural golden reflective light of natural hair, as can be seen in FIG. Instead, when using gardenia extract, it was found that the golden reflection of natural hair could not be realized.

Test example  4: cleaning Color fastness  analysis

Washing fastness (K / S) was measured by modifying the washing fastness test method of KS K ISO 105-C01. As for the test method, the sample hairs dyed according to the dyed Examples 1 to 3 and Comparative Examples 1 and 5 were diluted by diluting about 10 g in 1 L of water using a color-exclusive hemp agent and washed by hand for 2 minutes. After shaking 30 times with rinsing, it is naturally dried and each sample hair is measured with a colorimeter.

After shampooing each sample hair 1, 5, and 10 times by the above method, the results of measuring K / S values are summarized in Table 1 below.

Sample hair Washing fastness (K / S) 1 time shampoo 5 times shampoo 10 times shampoo Example 1 72.8 61.4 52.2 Example 2 70.5 59.7 53.8 Example 3 73.7 63.2 59.0 Comparative Example 1 56.0 19.5 12.4 Comparative Example 5 54 10.3 8.6

According to this, the hair dyed according to Examples 1 to 3 of the present invention shows that the K / S value is about 20 after shampooing 10 times and after shampooing 10 times, even after 10 times of shampooing. Appeared. On the other hand, the hairs of Comparative Examples 1 and 5 using Gardenia and Hwangbaek extract showed a difference in K / S value of 40 or more after shampooing once and after shampooing 10 times, confirming that the wash fastness was very low.

The present invention is characterized by dyeing the epidermis without permeating the dyeing solution into the cortex in order to prevent hair damage. When dyeing on the epidermis, conventional gardenia dyeing or yellow-white dyeing is very difficult to maintain the staining condition due to very poor wash fastness, but when the lacquer extract or the young eggplant extract of the present invention is used as a dye, washing fastness is significantly improved even when dyed on the cuticle can confirm. In addition, in the case of Example 3 using a mixture of extracts of lacquer extract and young mulberry extract, it was found that the wash fastness was further increased compared to Examples 1 and 2.
