Description

Gel-type natural hair dye and its manufacturing method {GEL-TYPE HAIRDYE USING NATURAL MATERIALS AND ITS MANUFACTURING METHOD}

The present invention relates to a natural hair dye, and more particularly, to provide a hair dye using the leaves of Lawsonia inermis , a natural hair dye, but it is made of a gel type, so that the dyeing is evenly made, which is a simple and non-irritating gel type. It relates to a natural hair dye and a preparation method thereof.

Hair dyes are classified into vegetable hair dyes, oxidized hair dyes, and metal plant mixed hair dyes, depending on the dye used and the principle of its color reaction.

Oxidative hair dyes are commonly used dyes these days, and dyes hair by the principle that oxidized young dyes penetrate the cuticle and precipitate pigment molecules in the cortex. Oxidizing hair dyes decolorize by oxidizing melanin pigment by an oxidizing agent, and dye penetrates to color. Oxidative hair dye has the best hair dyeing power and color lasting power among the hair dyeing methods, and has the advantage of being able to create countless shades.

Metallic plant-mixed hair dyes have an advantage in that they do not use oxidizing dyes, so there is no skin sensitization reaction, but there is a disadvantage that the dyeing procedure takes a relatively long time compared to oxidizing hair dyes. In addition, since the vegetable dye is dyed on the principle of forming a complex dye with the metal salt, which is a mordant, near the surface of the hair, the dyed color may be discolored due to sunlight, washing, friction, sweat, etc.

Vegetable hair dyes are dyed using logwood, andigo, chamomile, and henna. Plant hair dyes have an advantage in that they do not have a skin sensitization reaction, but they have a disadvantage of very weak color development and color persistence.

In recent years, so-called henna dyeing, which uses vegetable hair dyes with high stability on the skin as the main ingredient, has become popular.

However, the above henna dyeing is difficult to see as a pure natural hair dye because it is often mixed with an oxidizing dye for color development in various colors.

In addition, as in'Patent Document 1', since henna dyeing is used by dissolving powder in water, there is a high probability that the powder will be lumped during dyeing, and accordingly, the lumped part will become darker, and the part that is not will be relatively light. There is a problem that the degree of color to be dyed is different.

It should be construed as a meaning and concept, but not limited to a conventional or dictionary meaning.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention, and do not represent all the technical ideas of the present invention, and thus various equivalents that can replace them at the time of application It should be understood that there may be water and variations.

Prior to the description of the present invention, the natural materials used in the present invention will be briefly described.

Henna is a dye made from the leaves of the tropical shrub Lawsonia inermis , dried and powdered. It is usually a greenish brown powder, and it is mixed with water and used as mud. The henna tree is native to Egypt and grows in Pakistan, India, and Nepal. It grows in a dry area with high temperature, and the size is 2~3m. Since long ago, leaves have been used for hair dyeing and tattoos, and flowers have been used as raw materials for perfume. It also has a sterilizing effect, so it is also used as a medicine for skin diseases. The hair dyeing effect is due to the Lawsonia component contained in the leaves, and it is dyed reddish brown. It also has the effect of adding shine to the hair.

Agar is dried by freeze-dehydration or compression dehydration of soybean radish. Umu is usually made from seaweed from the Agaraceae family, such as Agar Agar, Agaric Agar, and Birdfoot. It can also be made from seaweeds such as Koshiraegi and Galaegombo. It is the seaweed of red algae that grows in the deep sea, and it has red or reddish purple color because it has a red color such as red algae in addition to chlorophyll.

Nokgak is a keratinized antler of various deer, such as manok or plum green, belonging to the deer family, and is an abbreviation in oriental medicine. The taste is salty, the nature is warm, and there is no poison, and it enters the two tens of the liver (肝) and kidney (臟腑). It promotes blood circulation, eliminates blood stagnation (瘀血), and helps kidney and liver function. In addition, it contains a large amount of calcium, which makes the bones strong. It is often used as a substitute for antler, but its effect is weaker than that of antler.

Hereinafter, a method for preparing a gel-type natural hair dye according to the present invention will be described.

The henna liquid manufacturing step (S10) is a step of processing henna serving as a dye. In general, in the case of natural dyeing, the leaves of Lawsonia Enemis are dried, crushed, and then used by dipping them in water. On the other hand, since the present invention is a gel-type composition, when the powder is used as it is, mixing with the gel composition is difficult. In addition, there is a problem in that the dyeing is not made evenly due to the debris even if the water-washed one is used. For example, the area where the residue is lumped becomes darker, and the area where it is not concentrated becomes relatively weak. In order to prevent such a problem, the present invention uses a henna solution from which the leaves of Lawsonia inemis are treated with a solvent, and then debris is completely removed.

In the henna liquid manufacturing step (S10), the leaves of the Lawsonia Inamis tree are well dried and then pulverized to make henna powder, which is then added to ethanol and then stirred to mix well using a stirrer. The ratio of henna and ethanol is 1:1.5-1:3, and the extraction time is about 2 hours. Henna liquid is finally prepared by filtering with a cotton cloth in order to remove the residue remaining from the henna powder mixture.

In addition, in the present invention, cypress oil may be used as a solvent in order to minimize irritation of ethanol. When using cypress oil, the extraction time is between 3 and 4 hours. Cypress oil has the advantage of extending the preservation period by minimizing the moisture content of the hair dye according to the present invention.

In addition, jojoba oil may be added to increase antimicrobial properties and reduce hair extension after dyeing.

The agar solution manufacturing step (S20) is a step of preparing an agar solution that serves to increase the viscosity so that the hair dye of the present invention becomes a gel type. Specifically, the dried agar is added to purified water and stirred at a temperature of 90-100° C. for 30 minutes to 1 hour to prepare an agar solution. Agar is generally used commercially available dried agar.

On the other hand, as the solvent used in the agar solution manufacturing step (S20), cypress water may be used instead of purified water. Cypress water is made by adding cypress trees to purified water and heating them to extract or reflux extraction. Cypress water contains phytoncide, which is widely known to be contained in cypress trees.Pytonside is a plant's self-defense substance, meaning a substance exhaled or secreted by plants to resist pathogens, pests, and fungi. The constituents of pythonside consist of terpenes, phenolic compounds, alkaloids, and glycosides. These pythonsides are natural substances, not chemicals, and are easily absorbed by the human body, and selectively sterilize bacteria harmful to humans. In addition, pythonsides are known to have numerous functions, such as antibacterial, deodorant, sedative and stress relief.

Accordingly, the hair dye according to the present invention can be safely used by soothing even on the skin sensitive to Lawsonia, and can prevent spoilage without additionally adding a preservative.

The nocturnal solution manufacturing step (S30) is a step of preparing a nocturnal solution that serves to increase the adhesive strength of the hair dye of the present invention. When the hair dye is applied to the hair, it increases adhesion to the hair so that the hair dye does not flow out and the dye material (Rosonia) can be absorbed into the hair. Specifically, nogak solution is prepared by putting the nocturne in purified water and stirring at a temperature of 90-100°C.

In addition, antler liquid may further contain antler. Deer deer of the Cervidae family (Cervidae) plum, Marok, and Daerok stag have dense hairs, and are cut off and dried. Deer usually can cut antlers about 3 years after birth, and the power to grow them is great, and the power to lead all the weak points and climb upward is strong.

The main components of antler are various free amino acids and polysaccharides, glycosaminoglycans (GAGs), hyaluronic acid, keratin, sialic acid, cholesterol, fatty acids, and phospholipids. , It has been reported to contain inorganic components. Looking at the distribution of active ingredients by part of antler, the content of minerals including collagen, ash, and calcium, which are indicators of chemical composition, increases as it goes down to the lower part of the antler, protein, fat, glycosaminoglycan, and sialic acid. The content of active ingredients such as, uronic acid decreases.

Such antlers are further included to supplement adhesion, supply nutrients such as keratin to the hair, and thereby increase the bonding strength between the dyeing material and keratin of the hair.

On the other hand, the solvent used in the nocturnal solution preparation step (S30) may use cypress water instead of purified water, and the resulting effect is the same as that in the agar solution preparation step (S20).

The first mixing step (S40) is a primary step of forming a hair dye in a gel type by adding henna liquid to the agar liquid. In the first mixing step (S40), the henna liquid made in the henna liquid preparation step (S10) and the agar liquid made in the agar liquid preparation step (S20) are mixed so that they are well mixed in a stirrer. At this time, since the lawsonia contained in the henna liquid is naturally decomposed, the heated agar liquid must be cooled to some extent, and at the same time, the henna liquid and the agar liquid must be well mixed. Mix at temperature.

It is preferable to mix the henna solution and the agar solution in a ratio of 1:2-1:3. If the ratio of agar solution is less than 1:2, the viscosity is too low to form a gel type, and if the ratio of agar solution is higher than 1:3, the content of lawsonia is low and dyeing is difficult. Does not.

The second mixing step (S50) is a secondary step of forming the hair dye into a gel type by imparting the adhesive force of the mixture of the first mixing step (S40). In the second mixing step (S50), the mixture of the first mixing step (S40) is mixed so as to be well mixed in a stirrer with the nocturnal solution prepared in the nocturnal solution manufacturing step (S30). At this time, as in the first mixing step (S40), the nocturnal solution is cooled to some extent, then mixed, and preferably mixed at a temperature of 20-30°C.

It is preferable to mix the first mixed solution and the antler solution in a ratio of 10:1-10:2.

Meanwhile, in the present invention, since a separate antioxidant is not added, and the agar solution and the green bark solution have high moisture content, there is a high possibility that they may be spoiled due to oxidation. To prevent this, you can add additional wine. Specifically, wine is added at 10% or less based on the weight ratio of the total hair dye.

Experimental Example 1. Stimulation test

1-1.Experimental process

In order to check whether the gel-type natural hair dye according to the present invention is irritated to the skin, an irritation test was conducted on panels in which itchy scalp or urticaria occurred during normal dyeing.

The panel was conducted for 10 males and females between their 20s and 40s, and the dyes of each example were applied sequentially around the crown with a size of about 2 cm in diameter, and washed after 20 minutes. In addition, whether itchy or hives felt by the panel was evaluated according to the 5-point measurement method. When the itching was the most severe, it was evaluated in units of 1 point based on 1 point, and 5 points for no itching. The results are shown in Table 1 below.

1-2. Experiment result

Example 1 Example 2 Example 3 Degree of itching 4.2±0.42 4.4±0.52 4.9±0.32

Since the examples were made of natural materials, the itching phenomenon hardly appeared, but among them, it can be seen that Example 3 is more stable to the skin than Examples 1 and 2.

Experimental Example 2. Color development test

2-1. Experiment process

In order to check whether the gel-type natural hair dye according to the present invention is uniformly colored and whether the color is well developed, a color development test was performed using a human hair sample.

For the color development test, hair was collected from an adult woman with healthy hair who owns long hair. Divided into 6 groups, the hair dyes of Examples 1 to 3 and Comparative Examples 1 to 3 were treated and dyed. Then, after treatment for 2 hours, it was rinsed with shampoo and dried with a dryer, and the degree of dyeing (color development) and whether the color was evenly dyed (color uniformity) were evaluated. The degree of color development was evaluated in units of 1 point based on 1 point for little color development and 5 points for good color development, and color uniformity was 1 point for inconsistent hair dyeing and 5 for uniform dyeing. It was evaluated in units of 1 point based on points. The results are shown in Table 2 below.

2-2. Experiment result

Color development Color uniformity Example 1 4.6±0.52 4.8±0.42 Example 2 4.4±0.52 4.5±0.53 Example 3 4.1±0.74 4.7±0.48 Comparative Example 1 4.7±0.48 1.8±0.42 Comparative Example 2 3.7±0.48 4.0±0.82 Comparative Example 3 4.5±0.53 3.1±0.57

In Examples 1 to 3, it can be seen that color development was well achieved, and the color was uniformly developed. However, in the case of Example 3 extracted with cypress oil, it can be seen that the color development degree slightly decreased compared to Example 1 extracted with alcohol, but this is not a significant degree.

On the other hand, in Comparative Example 1, it can be seen that the color uniformity is significantly inferior. In the case of Comparative Example 2 without the addition of the nocturnal solution, a flow-down phenomenon occurred somewhat even in the process of dyeing, and as a result, the degree of color development was also reduced.

In the case of Comparative Example 3 in which the henna powder debris was not completely removed using a cotton cloth, the color development degree was excellent, but the degree of uniformity was somewhat inferior.
