Description

Hair thickness and elasticity improvement patch applied to forehead hair loss, a composition for the patch, and a manufacturing method thereof

The present invention relates to a patch applied to forehead hair loss, a composition for the patch, and a method for manufacturing the same.

M-shaped alopecia that occurs on the forehead is hair loss that occurs frequently in men, and is caused by male hormones, overwork, stress, lifestyle habits such as unbalanced diet or excessive diet, excessive drinking or smoking.

There are M-shaped, U-shaped, and O-shaped types of hair loss, but in general, M-shaped hair loss occurs the most, and these Modern people who live in an age where appearance is important because they look older or have a bad impression because of the occurrence of M-shaped hair loss are experiencing many difficulties.

Among the many factors of M-shaped hair loss, the representative is that the frontal lobe, which is the part of the brain responsible for complex thinking, is used a lot due to the extreme stress that modern people face. It is known as one of the factors that cause M-shaped hair loss. In addition, as improper eating habits in oriental medicine can increase gastric fever, the M-shaped part of the forehead is where the stomach meridians (the meridians related to the stomach) pass. It is also known to gradually promote M-shaped hair loss.

Therefore, modern people who live in an era where appearance is important are struggling with M-shaped hair loss on the forehead, and are trying to solve it in various ways.

In particular, M-shaped hair loss is effective in preventing hair loss and growing hair even though the range of hair loss is somewhat smaller than other types of hair loss. It would be said that it is not a good choice to be over-measured, such as this, and in order to correct the forehead area where this em-shaped hair loss has progressed, a hair transplantation procedure was performed on the affected area, but the cost was high, and the painful point and time required during the procedure were high. The downside is that it takes a long time.

In addition, as disclosed in "Method for manufacturing a hair thickening agent applied to the forehead" (Korean Patent Publication No. 10-1158777, Patent Document 1), a hair thickening agent that temporarily makes hair appear rich in the forehead area of the emza may be used. However, this method uses a technique similar to makeup to lower some of the hair to the forehead with M-shaped hair loss and temporarily covers the thinning or insufficient part of the hair. There is also the disadvantage that it is easily smeared if you touch the forehead area.

In addition, there are some products that are applied or sprayed to treat EM-shaped hair loss, but it is cumbersome for busy modern people. There are problems with this.

Therefore, it is possible to concentrate the treatment on the characteristics of the forehead area where the M-shaped hair loss has progressed and a specific area of small size, and the ingredients effective for promoting hair growth and hair growth are deeply penetrated to the area around the hair root in the skin of the specific area, and for each case It can be applied flexibly to the forehead area where different types of M-shaped hair loss have progressed, and it minimizes the loss of active ingredients from the skin surface side and allows it to penetrate deep into the skin. and a patch-type product having a hair growth function and a method for manufacturing the same.

Techniques related to this include "Cosmetic composition for preventing hair loss and promoting hair growth comprising fine needle powder and natural extract as active ingredients" (Korea Patent Publication No. 10-2113645, Patent Document 2), "Prevention of hair loss and promotion of hair growth" A composition for cleaning hair and scalp having a function and a method for manufacturing the same” (Korean Patent Registration No. 10-2093543, Patent Document 3) were recently published.

However, each of the fine needles introduced in Patent Documents 2 and 3 and the extracts of medicinal herbs, plantain, chrysanthemum, chrysanthemum, sageum, and arborvitae have their own unique odors, thereby reducing the user's preference for use as cosmetics on their own. , there is a problem in that ingredients such as herbs and spices must be blended in order to have an appropriate odor.

The composition for patch applied to the forehead with M-shaped hair loss of the present invention is 0.7 to 0.9% by weight of willow bark extract, 9 to 11% by weight of spicule, 0.5 to 0.7% by weight of hydroxyacetophenone, and hydroxyethyl cellulose It is characterized in that it contains 1.1 to 1.3% by weight as an active ingredient.

The willow is a plant belonging to the genus Willow in the angiosperm phylum Dicotyledon, distributed in Korea, Japan, and China, and its scientific name is Salix koreenisis andersson.

The willow bark contains a large amount of a substance called 'salix alba', which is known to exert a strong pharmacological effect on delaying aging.

BHA, called salicin, plays a role in exfoliating epidermal cells, removing dead cells and creating space for new cells, thereby promoting skin regeneration, healing skin inflammation and soothing the skin. is known to have

The willow extract is an extract obtained by leaching the stem, branch, leaf, fruit, flower, root, bark (stem, branch and/or root bark) of plants of the genus Willow using a solvent such as water or alcohol, carbon dioxide It may be an extract obtained using a supercritical extraction solvent, or a fraction obtained by fractionating the extract.

This willow extract contains a component called salicin and has a bad odor.

In the present invention, the willow extract contains 0.7 to 0.9% by weight, more preferably 0.8% by weight.

Spicule is also called hydrolyzed sponge (Hydrolyzed Sponge), and is a skeletal tissue extracted from sponge, and a large amount of fine-sized pins are formed on the surface.

As the extraction method of the spicule, it may be prepared by a chemical purification process using a generally known acid or base, or it may be prepared by decomposing the protein obtained by adding a proteolytic enzyme such as protease to the sponge powder.

These spicules are sold in powder form in the market, and the content of needle needles on the market is only 10% by weight of the total weight, and the remaining ingredients are impurities, which may cause allergies and infections.

Therefore, it is preferable to use the spicule according to the present invention by making it into a small particle size of about 100 μm.

These spicules take a fine needle-like structure and stimulate the dermis of the scalp where the patch is attached, promote microcirculation, improve clogged capillaries to facilitate oxygen supply, and help cell regeneration by removing dead cells and dead skin cells. It provides anti-inflammatory and analgesic effects.

In particular, since the patch penetrates the scalp layer of the treated area to form a micro-channel, the active ingredient applied to the patch penetrates to the vicinity of the hair root to increase the penetration effect, and extremely fine artificial wounds that occur while the spicule penetrates the skin layer The active ingredients of the present invention (main active ingredients: hydroxyacetophenone, disodium EDTA, allantoin, hydroxyethylcellulose, willow extract) and the self-healing function of the skin It promotes skin regeneration and increases the bioactivity by increasing the temperature of the skin tissue around the hair root.

The spicule is a material harmless to the human body, and when it comes into contact with the skin, it stimulates the skin to form fine pores and is not particularly limited as long as it is a powdery material that can be dissolved or discharged from the body.

These spicules are characterized by a mild fishy smell.

In the present invention, the spicule includes 9 to 11% by weight of the spicule, and 10% by weight is most suitable.

Hydroxyacetophenone is a kind of organic compound extracted from plants such as comfrey, oak tree, and wheat sprout, and is usually used in cosmetics as a natural antioxidant.

Although hydroxyacetophenone has weaker preservative power than parabens, it is more friendly to the skin than parabens, as it not only improves the moisturizing function of the skin, but also helps to calm the skin and improve the skin barrier.

In addition, it has excellent stability at all temperatures and pHs, and has a low odor, making it suitable for use with eco-friendly raw materials.

In the present invention, hydroxyacetophenone is included in an amount of 0.5 to 0.7% by weight, most preferably 0.6% by weight.

Hydroxyethyl Cellulose improves the feeling of use and helps to stabilize the emulsion so that other ingredients do not separate from each other.

In addition, it is a film-forming agent that forms a thin film on the skin and hair, and is an emulsion stabilizer that improves viscosity or binds active ingredients in powder form.

When hydroxyethyl cellulose is added to water, it becomes a viscous liquid, and in general, when the concentration is doubled, the viscosity is improved by almost 5 to 10 times.

Such hydroxyethyl cellulose has the best salt resistance and pH stability among derivatives, but has a disadvantage in that it has a slight peculiar odor.

In the present invention, hydroxyethyl cellulose is included in an amount of 1.1 to 1.3% by weight, most preferably 1.2% by weight.

The active ingredients of the composition of the present invention described above each have their own unique odor, and herbs, fragrances, etc. have been blended in order to suppress such odors in the conventional cosmetic manufacturing method.

However, in the present invention, as an active ingredient, 0.7 to 0.9% by weight of willow bark extract, 9 to 11% by weight of spicule, 0.5 to 0.7% by weight of hydroxyacetophenone, and 1.1 to 1.3% by weight of hydroxyethyl cellulose. By doing so, it was possible to suppress the specific odor without using a separate fragrance or air freshener.

Most preferably, 0.8% by weight of willow bark extract, 10.0% by weight of spicule, 0.6% by weight of hydroxyacetophenone, and 1.2% by weight of hydroxyethylcellulose are preferably contained.

Glycerin is a component having the effect of lubricating and moisturizing, and is used as a conventional cosmetic raw material, and is included in 2.5 to 3.5 wt%, and is preferably contained in 3.0 wt%.

In addition, disodium EDIT is a metal ion sequestrant that blocks oxidation of metal ions or air from entering, and a component that prevents a small amount of metal from entering the skin.

In particular, Disodium EDI prevents product oxidation caused by metal ions, thereby preventing the color of the contents from changing, as well as preventing rancidity and change in flavor.

Therefore, it will make it possible to keep the product fragrance constant.

For this purpose, the disodium EDIT is contained in an amount of 0.02 to 0.04% by weight, preferably 0.03% by weight.

Allantoin is a natural component of plants such as sugar beet and wheat sprouts, which helps to soothe the skin, relieve troubles, and remove dandruff and dead skin cells.

Allantoin for this purpose is preferably contained in an amount of 0.01% by weight.

Sodium Hyaluronate is a natural moisturizing ingredient that can be obtained by culturing microbial strains. It plays a role of flexibility and elasticity between skin tissues, and has functions of water storage, lubrication, and nutrient storage.

In particular, it has a moisture content of 6,000 times higher than that of a general moisture factor and has a property of attracting moisture.

For this purpose, sodium hyaluronate is preferably contained in an amount of 0.01% by weight.

Xanthan gum is a mixture composed of glucose, mannose, and glucuronic acid after refining a high molecular polysaccharide gum material in isopropyl alcohol and drying and pulverizing it.

Xanthan gum itself is tasteless, odorless, and has high viscosity, which increases the viscosity and improves physical stability and spreadability.

Xanthan gum is contained in an amount of 0.15 to 0.25% by weight, preferably 0.2% by weight.

Ethylhexylglycerin is a kind of glycerin, and it is stable and safe, so it replaces the preservative role of existing phenoxyethanol or parabens.

Specifically, by increasing the antibacterial power of the preservative, the amount of the preservative is reduced, inhibiting bacterial growth, and used as a moisturizer.

Ethylhexylglycerin for this purpose is contained in an amount of 0.04 to 0.06% by weight, preferably 0.05% by weight.

The above-mentioned remaining ingredients may be contained in an appropriate amount to be able to utilize each function well.

In summary, the remaining ingredients are more preferably 2.5 to 3.5 wt% of glycerin, 0.02 to 0.04 wt% of disodium EDITA, 0.01 wt% of allantoin, and 0.01 wt% of sodium hyuronate, more preferably based on the above active ingredient , xanthan gum is composed of 0.15 to 0.25 wt%, ethylhexylglycerin is composed of 0.04 to 0.06 wt%, and purified water is preferably used as the remaining amount.

Most preferably, it is preferably composed of 3.0% by weight of glycerin, 0.03% by weight of disodium EDITA, 0.01% by weight of allantoin, 0.01% by weight of sodium haaluronate, 0.2% by weight of xanthan gum, 0.05% by weight of ethylhexylglycerin, and the remainder of purified water. Do.

In the above configuration, one or more of human stem cell culture extract, pea peptide, copper peptide, and pycnogenol may be added to blend within 10%.

In this case, the content of other components does not change, and it is also composed of the remaining amount of purified water.

Human stem cell culture extract refers to stem cells obtained from adults other than embryonic stem cells, and includes, for example, all stem cells originating from the base of blood and tissues including fat, bone marrow, umbilical cord blood and peripheral blood, not limited The use of human stem cells in the cosmetic field uses growth factors as metabolites, and growth factors bind to receptors on the surface of cells to stimulate cell proliferation and differentiation. growth factor), TGF (transforming growth factor), HGF (hepatocyte growth factor), FGF (fibroblast growth factor), IGF (insulin-like growth factor), SOD (antioxidant enzyme), collagen, fibronectin, etc. .

Pea peptides are peptides of peas, and peas contain about 56% of carbohydrates and about 22% of proteins, and more than half of the proteins are globulins. It is a protein called legumin and contains a large amount of amino acids. As minerals, calcium and phosphorus are abundant, and in addition, vitamins B1, B6, biotin, choline, and chlorophyll are abundant. Since it contains various antioxidant enzymes (superoxide dismutase) and antioxidants such as propyl gallate, tocopherol, and selenium, it protects cells by eliminating reactive oxygen species in the living body.

Copper peptide (copper complex) inhibits 5 alpha-reductase, reduces the production of DHT, normalizes the shortened hair growth cycle, helps to thicken hair, and removes excess active oxygen generated around hair follicle cells. It is known to protect the hair root by removing it and to smoothly supply nutrients to the hair by participating in the formation of capillaries on the scalp.

Pycnogenol refers to a flavonoid complex extracted from French sea pine bark extract, and is known to suppress free radicals that damage skin cells with strong antioxidant power.

The patch of the present invention comprising the composition as described above, 0.7 to 0.9% by weight of willow bark extract, 9 to 11% by weight of spicule, 0.5 to 0.7% by weight of hydroxyacetophenone, 1.1 to 1.3 hydroxyethyl cellulose The patch composition 10 containing weight % as an active ingredient is impregnated or applied to the patch body 20 .

At this time, as shown in FIG. 1 , the patch body 20 forms a high-density layer 11 having a high composition content on one side on a plane surface, and a low-density layer having a lower composition content than the high-density layer 11 on the other side. (13) can be formed.

This allows the supply of the composition to be more actively performed in the part close to the part where the hair is currently located, and the supply of the composition is relatively low in the part that is relatively far away to form a more natural hairline.

In the drawings, reference numeral 12 denotes the intermediate layer 12 in which the content (or density) of the composition is between the high-density layer 11 and the low-density layer 13 .

As such, it will be said that the composition to have a differentiated density is not limited to the three steps shown in the drawings, and can be installed by various adjustments.

On the other hand, as can be seen from the drawings, the patch body 20 may have minute concavities and convexities 21 formed on the end side of the high-density layer 11 side on a flat surface.

The irregularities 21 are also formed in order to produce a more natural hairline.

On the other hand, in the present invention, the patch body 20 is transparent by itself or has the color of the wearer's skin color, thereby making it difficult to identify whether it is worn during daily activities.

Nevertheless, it is difficult to make them completely indistinguishable visually.

As a method to solve this problem, as shown in the cross-sectional view on one side of FIG. 1 , the upper part of the patch body 20 is transparent or takes a skin color, and a wig patch 30 in which a plurality of artificial hairs 40 are installed is installed. can be

< 0: bad smell, 9: good smell>

As seen from Table 4 above, it was found that the compositions of Examples had better initial odor than those of Comparative Examples.

In addition, it can be seen that the compositions of Examples after 10 months had a good odor, while the odors of the Comparative Examples were seriously deteriorated.

That is, it is determined that only when the active ingredient is limited, the odor can be suppressed.
