Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and the same reference numerals in each drawing refer to the same components.

FIG. 1 is a conceptual diagram showing a schematic configuration of a cosmetic composition of the present invention, and as can be seen from FIG. 1, the cosmetic composition having a skin recovery and soothing function of the present invention consists of a mixture of a base group and an extract group.

Specifically, the cosmetic composition may be a mixture of 70 to 95% by weight of the base group including butylene glycol and glycerin, 5 to 30% by weight of the extract group including avocado extract and yam root extract, based on the total weight of the cosmetic composition.

The base group includes butylene glycol and glycerin, and imparts emulsion stability and a function of preventing freezing to the cosmetic composition of the present invention.

At this time, butylene glycol is one of polyols having two or more hydroxyl groups (-OH) and is widely used as a moisturizer for general cosmetics. This butylene glycol has a feature of providing a fresh feeling because it has less skin irritation, has antibacterial properties, and has a lighter feeling than glycerin, which will be described later. In addition, glycerin is also a material that is widely used as a moisturizer in cosmetics, and has excellent moisture absorption properties and can provide a rich moisturizing sensation to the skin. Such butylene glycol and glycerin may be present in various ratios in the base group, for example, butylene glycol: glycerin may be mixed in a ratio of 1:1 or 3:1. Here, in addition to butylene glycol and glycerin, the base group may include purified water or other ingredients that can provide emulsion stability to the cosmetic composition, if necessary.

The extract group includes avocado extract and yam root extract, and imparts skin recovery and soothing functions to the cosmetic composition of the present invention.

At this time, avocado extract is a component extracted from the fruit of high-nutrition avocado that contains 30% fatty acids and a large amount of carbohydrates and proteins, and can help to maintain the flexibility of the skin by inducing the synthesis of collagen and elastin. It has good absorption and can effectively nourish dry skin. In addition, yam root extract is a component extracted from the root of yam, and it is also called vegetable snail mucus because it contains a large amount of a snail mucus-like component called phytomucin. The phytomucin of these chamba root extract helps to relieve irritated skin and prevent damage, helps to manage skin traces, and forms a natural moisturizing film that protects the skin by containing mutin, saponin, and allantoin. It can be helpful for grain management.

The above-described avocado extract and yam root extract may be present in various ratios within the extract group, for example, avocado extract: yam root extract may be mixed in a ratio of 1:1 or 1:5.

At this time, the extract group may additionally contain other extracts that can help the function of the skin in addition to the avocado extract and the yam root extract.

In addition, the cosmetic composition may additionally include a functional group including asiaticoside and madecassoside, and may be added and mixed in a smaller ratio than the base group and the extract group.

Specifically, the functional group including asiaticoside and madecassoside is added in a ratio of 70 to 90% by weight of the base group, 5 to 25% by weight of the extract group, and 0.1 to 5% by weight of the functional group, based on the total weight of the cosmetic composition. Can be.

First, Asiaticoside generally plays a role as an antioxidant and skin conditioning agent, and is a natural organic compound that is one of the extracts of Centella asiatica. At this time, asiaticoside can reduce skin irritation, improve skin elasticity, and has an antioxidant effect to make the skin supple and smooth. In addition, by supplying nutrients to the skin, it can help improve damaged skin and traces created on the skin, and can be applied to various skin types such as dry, oily, and sensitive skin.

Next, Madecassoside is also one of the extracts of Centella asiatica, which can protect the skin from external harmful environments, and it contains triterpene, which is a pharmacological component of plants. It can protect and soothe the skin, and it can effectively control sebum. In addition, it has the advantage of being stable because it is suitable for use on dry, oily, and sensitive skin.

These asiaticosides and madecassosides may be mixed and present in various ratios within the functional group, and other functional ingredients that are not harmful to the skin may be additionally included together. For example, asiaticoside and madecassoside may exist in various ratios such as 1:1 or 1:2 within the functional group.

As another example, the extract group of the cosmetic composition may additionally include an aloe extract and a kelp extract.

First, aloe extract is a juice obtained from the leaves of aloe, and is a folk medicine in various countries since ancient times. It has been used for hemostasis, inflammation relief, pain stop, purulent prevention, and promotion of granulation tissue regeneration in trauma. In addition, it has the advantage that it is not irritating to the skin, can impart glossiness, and is excellent in skin soothing effect.

Next, kelp extract is rich in vitamins C and E, which are good for the skin, so it can make the skin shiny and elastic, and it is also effective in removing dead skin cells and preventing skin aging. In addition, since it suppresses melanin pigment, it is good for whitening the skin and soothes hot skin, it can be particularly good when used in summer when UV rays are strong.

These aloe extract and kelp extract may be mixed with the avocado extract and yam root extract described above in various ratios, and there is no specific limitation on the mixing ratio thereof. In addition, other extracts that may be helpful for skin recovery and soothing may be additionally included and mixed together.

As another example, the functional group including asiaticoside and madecassoside may additionally include oligopeptides and ceramides.

First, an oligopeptide refers to a peptide consisting of 2 to 20 amino acids. It is similar to a component involved in skin regeneration and can promote the synthesis of collagen in the skin. It can help improve elasticity and wrinkles. In addition, it is possible to promote the removal of aging dead skin cells, thereby promoting a turn-over cycle of the skin, thereby helping to repair skin wounds and improve aging skin.

Next, ceramide is a fatty (fat) component present in a high content on the skin surface layer, and forms a protective film on the surface of the skin to prevent moisture loss and protect the skin from external harmful environments and contamination. In addition, ceramide is an ingredient that is superior to anti-aging than retinol, niacinamide, and peptide. It strengthens the skin barrier and increases moisture, so you can feel soft, elastic skin, relieve wrinkles, and relieve sensitivity. . In addition, since it is an ingredient naturally contained in the skin, it is suitable for all skin and can be used on thin and sensitive skin such as the eye area as long as it does not contain fragrance and irritating ingredients. These ceramides are most effective when used in combination with other skin supplement ingredients, such as fatty acids, glycerin, and cholesterol.

As another example, the cosmetic composition of the present invention may additionally include an elasticity aid containing hyaluronic acid, thereby improving the elasticity of the skin and helping to prevent aging of the skin.

Specifically, the elasticity aid may be additionally included in an amount of 1 to 5% by weight, based on the weight of the total cosmetic composition.

At this time, such an elasticity aid may be encapsulated by encapsulating an elastic material containing hyaluronic acid by a coating film, whereby the material that enhances the elasticity of the skin is not damaged and can be maintained for a long time to provide an effect. .

Figure 2 is a flow chart showing a method of manufacturing a coating film of the elasticity aid of the present invention.

Such a coating film may be manufactured through a first mixed solution manufacturing step (S110), a second mixed solution manufacturing step (S111), a coating agent manufacturing step (S112), and a coating film completion step (S113).

First, the first mixed solution preparation step (S110) is based on the total weight of the first mixed solution, 55 to 70% by weight of water, 25 to 35% by weight of PVA (Poly (vinyl alcohol)), PEG (Poly(ethylene glycol)) 5 After mixing to 15% by weight, it is heated to 80 to 95°C to prepare a first mixed solution. Here, PVA has excellent mechanical properties and can be solidified later to form a gel-like film. In addition, PEG is an additive for inducing hydrogen bonding between molecules of the PVA chain or intramolecularly.

Next, the second mixed solution preparation step (S111) is a second mixing by mixing 30 to 80% by weight of hexane and 20 to 70% by weight of PLGA (poly(lactic-co-glycolic acid)) based on the total weight of the second mixed solution. As a process of preparing a solution, it is preferable to prepare by stirring for 5 to 10 minutes at a speed of 15,000 to 25,000 rpm.

Here, hexane serves as a solvent capable of dissolving PLGA, and PLGA can be solidified as a biotype polymer that can be simply hydrolyzed without the action of enzymes in the body to form a membrane.

Thereafter, the coating agent manufacturing step (S112) is a process of preparing a coating agent by mixing 50 to 70% by weight of the first mixed solution and 30 to 50% by weight of the second mixed solution, based on the total weight of the coating agent, and completing the coating film (S113). ) Is a process of cooling the coating agent to complete the coating film, and cooling is preferably performed to a temperature of room temperature (about 10 to 30°C).

The coating agent completed through this process can be solidified to form a coating film having excellent physical properties, thereby stably protecting the above-described elasticity aid. In addition, since it is biodegradable, it can be naturally decomposed and removed after a certain period of time in the body, and through this, the elasticity effect of the skin can last a long time.

Figure 3 is a flow chart showing a method of manufacturing the elastic material of the elasticity aid of the present invention.

At this time, the elastic material that is the core material of the elasticity aid described above is the first solution preparation step (S120), the first material acquisition step (S121), the second material acquisition step (S122), the third solution preparation step (S123), It can be prepared through the 4 solution preparation step (S124), the third material obtaining step (S125), and the elastic material completion step (S126).

First, the first solution preparation step (S120) is 50 to 60% by weight of water, 30 to 40% by weight of PEGDE (Poly(ethylene glycol) diglycidyl ether), and 0.1 to 10 of hyaluronic acid, based on the total weight of the first solution. It is a process of preparing a first solution by mixing wt% and then heating at 50 to 70°C for 1 to 3 hours, and the first material obtaining step (S121) is after freeze-drying the first solution at -60 to -40°C. This is a process in which the obtained product is washed 1 to 3 times with water and then freeze-dried again to obtain a first material.

Here, hyaluronic acid forms a substrate in the synovial fluid of joints, skin, and umbilical cord, as well as connective tissue, and exists in a gel state.It acts as an adhesive in the skin tissue and acts as a tissue barrier to prevent the passage of infectious substances such as bacteria. It can be used, and it plays the role of supplying moisture to the skin. In addition, PEGDE may be bonded to an alcohol group (-OH) having a hyaluronic acid structure to modify hyaluronic acid. That is, it is possible to improve the reactivity with collagen, which will be described later. Therefore, the obtained first material can be said to be hyaluronic acid whose surface has been modified.

Thereafter, in the second material obtaining step (S122), a second solution is prepared by mixing 70 to 85% by weight of a PBS (Phosphate Buffered Saline) solution with a pH of 7.4, and 15 to 30% by weight of the first material based on the total weight of the second solution. After filtration, a second material is obtained as a residue. Here, the reason for using a PBS solution having a pH of 7.4 is that it is stable to be applied to living organisms having this pH concentration. Therefore, the second substance is adjusted to adjust the first substance to a pH concentration suitable for living organisms.

Next, the third solution preparation step (S123) is a process of preparing a third solution by mixing 90 to 99.9% by weight of a pH 3 hydrochloric acid solution and 0.1 to 10% by weight of collagen based on the total weight of the third solution. Here, collagen, as a protein structural material, is involved in maintaining the body shape of an animal, and is included in human tissues such as dermis, tendons, blood vessels, bones, and teeth. At this time, collagen is a fibrous protein found in most animals, especially mammals, and occupies most of all connective tissues in the body, such as skin and cartilage, and can provide a moisturizing effect to the skin. In addition, the hydrochloric acid solution can dissolve collagen and serves as a solvent for the third solution.

Thereafter, the fourth solution preparation step (S124) is a fourth solution by mixing 70 to 90% by weight of the third solution and 10 to 30% by weight of the second material at 30 to 40°C for 20 to 30 hours based on the total weight of the fourth solution. In the process of preparing a solution, the third material obtaining step (S125) is a process in which the fourth solution is freeze-dried at -55 to -45°C, washed 1 to 3 times with water, and then freeze-dried again to obtain a third material. . Here, the fourth solution is a solution obtained by mixing a second material, that is, a modified hyaluronic acid and a collagen solution, and a hyaluronic acid-collagen complex may be prepared. That is, the obtained third substance is a hyaluronic acid-collagen complex.

Finally, the elastic material completion step (S126) is a process of completing the elastic material by mixing 5 to 30% by weight of the third material and 70 to 95% by weight of the PBS solution based on the total elastic material weight. Here, it is preferable to use the PBS solution having a pH concentration of 7.4 as described above, and it is mixed in order to adjust the elastic material to a suitable pH concentration for application to the skin.

The elastic material produced through this process is a component of the human body and is a complex made from collagen and hyaluronic acid suitable for the body, so it is harmless to the human body, and it is effective in improving the elasticity of the skin and preventing aging of the skin. There is.

As described so far, the cosmetic composition having a skin recovery and soothing function according to the present invention is expressed in the above description and drawings, but these are only described as examples, and the spirit of the present invention is not limited to the above description and drawings, It goes without saying that various changes and changes can be made without departing from the technical spirit of the present invention.
