METHOD FOR EXTRACTING USING GLACIAL WATER AND THE EXTRACT THEREOF, AND COSMETIC COMPOSITION COMPRISING NAMOEMULSION PARTICLES HAVING THE EXTRACT ENCAPSULATED OR THE GLACIAL WATER
The present invention relates to a method for extracting an active ingredient by using glacier water, accumulated for a long period of time, as an extraction solvent, an extract thereof, and a cosmetic composition comprising nanoemulsion particles having the extract encapsulated by the nanoemulsion technology to improve transdermal permeation, in which the extracts contain various minerals or active ingredients. Also, the present invention relates to a cosmetic composition comprising glacier water as an active ingredient to supply moisture to the skin, to reduce loose keratin and to soften the skin texture.
In high mountains or polar regions, snow has been accumulated without thawing for a long period of time to form perpetual snow, which turns hard icecaps by pressure. Here, water produced from the icecaps is called "glacier water".
At present, the glacier water is formed in the polar regions, one of the cleanest regions on the earth or high mountains, representing health and pure liveliness of the nature. Representative glacier water-producing regions include Vilcabamba of Ecuador, Abkhasia of Caucasus or Hunza of Himalaya.
The glacier water has a structure in which microorganisms or pathogenic bacteria hardly propagate and has a high rate of hexagonal water. Also, it contains a large amount of minerals. Therefore, the regions where the glacier water is produced are famous for long-lived towns.
Minerals support osmotic pressure and acid-alkali equilibrium in the living body, control healing of the wounded and metabolic functions in the body and play an important role in oxygen transmission and cell respiration. Therefore, studies on a novel solvent extraction method to increase transdermal absorption of the minerals are actively in progress.
According to the conventional solvent extraction method, an extraction process including mixing an object material with water; an organic solvent such as ethanol, methanol, butanol, ether, ethylacetate and chloroform; or a combination of water and an organic solvent and leaving the mixture at room temperature for one day, followed by extraction, is repeated at least twice to obtain an extract. The extract is filtered and the resulting filtrate is concentrated in a vacuum concentrator to obtain a primary product.
To the primary product, water and an organic solvent such as ethanol, methanol, butanol, ether, ethylacetate or chloroform are added and left at room temperature for 2 hours for phase separation. The aqueous phase was removed and the organic solvent is further added. This procedure is repeated at least 2 times for sufficient washing, followed by filtering. The resulting filtrate is dried in a vacuum oven to obtain the desired extract.
This conventional solvent extraction method has several problems such as safety related problems due to residual organic solvents and formulability and stability related problems upon combination of cosmetic products and thus, there is a demand for a novel solvent extraction method to solve those problems.
Also, it is greatly desired to develop a novel solvent extraction method to increase absorption of active ingredients such as minerals while securing safety.
Accordingly, the present inventors have conducted studies to solve the skin safety related problems caused the residual organic solvents the prior and to find a solvent substituting for the organic solvents. As a result, the present inventors have found that when active ingredients are extracted using glacier water instead of water or organic solvents, it is possible to increase absorption of the active ingredients while maintaining safety to the skin. Also, by encapsulating the extract prepared therefrom in nanoemulsion particles by nano technology, it is possible to provide a cosmetic composition with improvement of transdermal absorption. On the basis of this development, the present invention has been completed.
Further, the present inventors have found that the molecular structure of glacier water is similar to that of water molecule found in the living tissue and thus, readily absorbed through the skin, leading excellent moisturizing effect. On the basis of this founding, the present invention has been completed.
Therefore, it is an object of the present invention to provide a method of extracting an active ingredient for safe application to skin and excellent absorption of the active ingredient and an extract prepared therefrom, and a cosmetic composition comprising the extract as an active ingredient.
Also, it is an object of the present invention to provide a cosmetic composition for increasing skin moisturizing effect, reducing keratin formation and smoothing skin texture.
To achieve the above objects, the present invention provides a method of extracting an active ingredient by using glacier water, accumulated for a long period of time, as an extraction solvent, an extract thereof, and a cosmetic composition comprising nanoemulsion particles having the extract encapsulated by the nanoemulsion technology, as an active ingredient, to improve transdermal permeation, in which the extract contains various minerals or effective ingredients.
Further, the present invention provides a cosmetic composition comprising glacier water as an active ingredient.
According to the present invention, the extraction of active ingredients is performed by using glacier water rich in natural minerals. As a result, it is possible to provide safety upon application to the skin, increase effects of active ingredients. Also, transdermal absorption of a cosmetic composition is maximized by stabilizing the extract in nanoemulsion particles through encapsulation using an emulsion affinitive to skin.
In addition, the cosmetic composition comprising the glacier water according to the present invention has superior skin moisturizing effect and increase skin moisture content, thereby reducing keratin and roughness and smoothing the skin surface.

Hereinafter, the present invention will be described in detail.
The glacier water used according to the present invention may include any one produced in Hunza of Himalaya, Vilcabamba of Ecuador or Abkhasia of Caucasus, preferably Himalaya glacier water produced in Hunza of Himalaya.
The Himalaya glacier water, also called "Hunza water" has a unique colloidal structure of nano-sized silica particles. Accordingly, it has a low surface tension and thereby, can let an active ingredient be readily absorbed to the human body or skin. Also, the Himalaya glacier water has a molecular structure of a bird cage shape similar to a hemisphere dome, which can trap a large amount of hydrogen. Such water molecule structure has a small amount of colloidal inorganic compound particles having a high zeta potential. Here, the shape of the formed water molecule is known to be considerably similar to that of the water molecule found in the living tissue but quite different from that of the water molecule found in common mineral waters and tap water.
According to the present invention, there is provided a method of solvention extraction using glacier water. The method comprises the steps of:
1) repeating an extraction process at least two times and concentrating the resulting filtrate in a vacuum concentrator to obtain a primary product, in which the extraction process includes immersing a plant in glacier water at room temperature for one day and filtering; and
2) adding glacier water to the product, stirring the mixture at room temperature for at least 2 hours, followed by sufficient washing, filtering the mixture and drying in a vacuum oven to obtain an extract.
In the present invention, the glacier water has undergone natural filtering apparatuses such as granite, gravel and small grains, while it thawed into water. The filtered glacier water is obtained from the ground water aquifer at the depth of several kilometers under the ground and is clean and not contaminated since while protected by a natural barrier of granitic layer. Therefore, the method of the solvent extraction using the glacier water according to the present invention simplifies the filtration process unlike the conventional methods using organic solvents, thereby readily producing the extract.
The effective minerals such as sodium, magnesium, potassium and calcium, and zinc, copper, vanadium and manganese contained the glacier water can be rapidly absorbed through the skin. Also, the glacier water has purifying effect by removing toxic substances and thus, microorganisms or bacteria cannot propagate therein. Therefore, according to the present invention, there is provided a cosmetic composition which can be used with regardless to skin types of users and be even safely used by infants or those with skin troubles such as atopic dermatitis patients.
The active ingredients which can be extracted by the method according to the present invention includes, but are not particularly limited, β-1,3-glucan, papain, polyphenol, saponin, adenosine, vitamin C (ascorbic acid), arbutin, niacinamide and acetylglucosamine.
The β-1,3-glucan extracted by the method according to the present invention is a glucan having a high purity of at least 98% and extracted from mycelium Schizophyllum commune and effective in prevention of skin aging and healing of damaged skin. Also, in addition to Schizophyllum commune, the β-1,3-glucan can be extracted from Ganoderma japonicum, Agaricus blazei Muill, Lentinus edodes, Sclerotinia sclerotiorum, yeast and barley using the glacier water according to the solvent extraction method according to the present invention.
Further, the papain of the active ingredients can be extracted from fruit or tree of papaya and polyphenol can be extracted from anthocyanin pigments of red or purple colors contained in green tea, coffee, strawberries, eggplant, red beans and the like, red wine, black bean or cacao.
Saponin can be extracted from bean, ginseng or yam, adenosine can be extracted from plants such as wild parsley, vitamin C (ascorbic acid) can be extracted from Rubus Coreanus, persimmon tree leaf, rosehip, grapefruit or pimento, arbutin can be extracted from Arctostaphylos uva ursi, niacinamide can be extracted from potato or avocado and acetylglucosamine can be extracted from the dried bark of

and Phellodendron chinense SCHNEID.
Further, according to the present invention, the extract (active ingredients) extracted using glacier water can be encapsulated into fine emulsion particles or liposomes by applying nanoemulsion technology, whereby, the transdermal absorption of minerals contained in the glacier water is increased. The extracted with the glacier water is contained in the amount of 0.001 to 50 wt% based on the total weight of the emulsion particles or liposomes. When the amount of the extract is less than 0.001 wt%, the effect of the active ingredients is not sufficiently expressed. When the amount exceeds 50 wt%, the formulation is hard. According to the present invention, the nanoemulsion particles comprising the extract can be prepared by a conventional high pressure emulsifying method, as a nanoemulsion technology, at a pressure of 500 to 1000 bar.
The emulsion particles according to the present invention have a diameter of 1000 nm to 30 nm, preferably 300 nm to 50 nm. The nanoemulsion particles or liposomes have the contact surface with the skin increased and thus, the area for transdermal absorption increased. Also, the emulsion particles according to the present invention can be readily absorbed or diffused into lipid between cells since the gap between lipid molecules in the stratum corneum is about 50 nm and the emulsion membrane of the emulsion particles is flexible. That is, the emulsion particles having an average diameter of 300 nm to 50 nm, as prepared by the nanoemulsion technology, increase the transdermal permeation of the emulsion particles themselves and the extract in the emulsion particle by increase in contact area with the skin; permeation and diffusion through lipids between cells; and the extract extracted by using glacier water.
Meanwhile, the emulsion particles according to the present invention may further comprise lecithin as an emulsifying agent along with the extract and the content of lecithin is 0.5 to 5 wt%, preferably 2 to 4 wt%, based on the total weight of the emulsion particles. The content of lecithin is an effective amount to form a stable formulation of the cosmetic composition. The lecithin comprises unsaturated choline based compounds such as phosphatidylcholine, lysophosphatidylcholine and phosphatidylethanolamine, and hydrogenates thereof.
Also, according to the present invention, the emulsion particles may include various non-ionic surfactants as a subsidiary emulsifying agent, preferably fatty alcohol complex surfactants or high molecular weight surfactants. The subsidiary emulsifying agent is used in a weight ratio of 0.1 to 5 times, preferably 0.5 to 2 times, based on the weight of lecithin according to the weight and ingredients of lecithin.
Also, according to the present invention, there is provide a cosmetic composition comprising emulsion particles or liposomes having the extract, extracted by using glacier water, encapsulated therein. The cosmetic composition according to the present invention contains the emulsion particles or liposomes in the amount of 0.001 to 50 wt% based on the total weight of the composition. When the content of the emulsion particles or liposomes is less than 0.001 wt%, the active ingredients hardly express their effects in formulations. When the content exceeds 50 wt%, the formulation is hard. Further, the cosmetic composition may selectively further comprises glacier water as an active ingredient.
In addition, according to the present invention, there is provided a cosmetic composition comprising glacier water. The glacier water is contained in the amount of 0.1 to 100 wt% based on the total weight of the composition. When the content of the glacier water is less than 0.1 wt%, the effect of glacier water is poor. The cosmetic composition comprising glacier water according to the present invention can supply moisture to the skin, reduce keratin in the skin and reducing the skin roughness, thereby softening the skin texture.
The cosmetic composition according to the present invention can be formulated in various formulations without any particular limitation. For example, the formulations include skin softener, skin toner, skin lotion, nourishing cream, massage cream, essence, eye cream, eye essence, cleansing cream, cleansing foam, cleansing water, pack, powder, body lotion, body cream, body oil, body essence, make-up base, foundation, hair manicure, shampoo, rinse, body cleanser, toothpaste and mouth gaggle, skin whitening cosmetic products or medical supplies such as ointment and patch.

Experimental Example 4: Measurement of increase in moisture content in skin through moisture supply by using glacier water
The group who applied the skin toner (Formulation 2) or cream (Formulation 3) containing glacier water (supplied from Huza of Himalaya) to the skin and the group who applied the skin toner (Comparative Formulation 4) or cream (Comparative Formulation 5) without containing glacier water were measured for the moisture content in the skin and their results were compared. The skin toner and the cream were separately applied different groups to examine the increase in the moisture content by each product without interaction between the products. Each group includes 20 healthy adult women.
In the first visit, the forearm was washed clean and stood by for 30 minutes in a constant-temperature and constant-humidity room (23℃, RH 40%) for adaptation of the skin. After 30 minutes later, the initial moisture content of the skin in the forearm was measured using a corneometer (CM825, C+K Electronic Co., Germany). The corneometer measures the moisture content in the skin by measuring electrical conductivity of the skin. Then, 2 ㎕/㎠ of the cosmetic composition was applied to 15 ㎠ of the previously indicated part of the forearm. After 3 hours, 6 hours and 9 hours (including 12 hours for the skin toner), the part of the skin where each Formulation was applied was measured for the water content. The result of the group using the product containing glacier water was compared with that of the group using the product without containing glacier water to determine the moisturization and water-retaining power of the products. The result is shown in Table 8 (unit: AU).

Formulation 3(cream AD, with containing glacier water) 26 68 55 51 -
Comparative Formulation 5(cream, without containing glacier water) 26 58 50 46 -
From the result of Table 8, it was noted that the skin applied with Formulations 2 and 3 contained more moisture than the skin applied with Comparative Formulations 4 and 5.
Experimental Example 5: Measurement of reduction in amount of keratin through moisture supply by using glacier water
Since the amount of keratin was reduced, the group who applied the skin toner (Formulation 2) or cream (Formulation 3) containing glacier water (supplied from Huza of Himalaya) to the skin and the group who applied the skin toner (Comparative Formulation 4) or cream (Comparative Formulation 5) without containing glacier water were measured for the amount of keratin in the skin by image analysis and their results were compared. Each group includes 20 healthy adult women.
In the first visit, the forearm was washed clean and stood by for 30 minutes in a constant-temperature and constant-humidity room (23℃, RH 40%) for adaptation of the skin. After 30 minutes later, in order to measure the initial amount of keratin of the forearm, loose keratin was taken using a tape. Then, 2 ㎕/㎠ of the cosmetic composition was applied to 15 ㎠ of the previously indicated part of the forearm. After 3 hours, 6 hours and 9 hours (including 12 hours for the skin toner), the part of the skin where each Formulation was applied was measured for the keratin amount. The result of the group using the product containing glacier water was compared with that of the group using the product without containing glacier water by image analysis and it was confirmed that the product containing glacier water had the skin moisturizing and soothing effect. The result is shown in Table 9 and FIG. 1 and FIG. 2 (unit: AU).
Table 9

Formulation 3(cream AD, with containing glacier water) 19 2 4 5 -
Comparative Formulation 5(cream, without containing glacier water) 19 4 5 6 -
From the results of Table 9 above and FIG. 1 and FIG. 2, it was noted that Formulations 2 and 3 reduced the keratin amount much more than Comparative Formulations 4 and 5 and thus, the products containing glacier water were more effective in moisturizing and soothing the skin.
Experimental Example 6: Measurement of reduction in skin roughness through moisture supply by using glacier water
The group who applied the skin toner (Formulation 2) or cream (Formulation 3) containing glacier water (supplied from Huza of Himalaya) to the skin and the group who applied the skin toner (Comparative Formulation 4) or cream (Comparative Formulation 5) without containing glacier water were examined for the skin roughness and their results were compared. Each group includes 20 healthy adult women.
In the first visit, the forearm was washed clean and stood by for 30 minutes in a constant-temperature and constant-humidity room (23℃, RH 40%) for adaptation of the skin. After 30 minutes later, the skin roughness was measured using a 3D scanner, PRMOS compact (G.F.M., Germany). Then, 2㎕/㎠ of the cosmetic composition was applied to 15㎠ of the previously indicated part of the forearm. After 9 hours (including 12 hours for the skin toner), the same part of the skin was measured for the skin roughness. The result of the group using the product containing glacier water was compared with that of the group using the product without containing glacier water and it was confirmed that the product containing glacier water had the effect of smoothing skin texture. The result is shown in FIG. 3 to FIG. 6.
From the results of FIG. 3 to FIG. 6, it was noted that Formulation 2 and Formulation 3 reduced the skin roughness much more than Comparative Formulation 4 and Comparative Formulation 5 and thus, the products containing glacier water were more effective in smoothing the skin texture.
Experimental Example 7: Measurement of reduction in roughness of the stratum corneum by using glacier water
The stratum corneum samples were taken from both the group who applied the skin toner (Formulation 2) or cream (Formulation 3) containing glacier water (supplied from Huza of Himalaya) to the skin and the group who applied the skin toner (Comparative Formulation 4) or cream (Comparative Formulation 5) without containing glacier water to the skin and subjected to a pretreatment. Then, the samples were measured for the roughness and the results were compared. Each group includes 20 healthy adult women.
In the first visit, the forearm was washed clean and stood by for 30 minutes in a constant-temperature and constant-humidity room (23℃, RH 40%) for adaptation of the skin. After 30 minutes later, samples of the stratum corneum were taken (Skin surface biopsy). Then, 2 ㎕/㎠ of the cosmetic composition was applied to 15 ㎠ of the previously indicated part of the forearm. After 9 hours (9 hours and 12 hours for the skin toner), samples of the stratum corneum in the same area were taken, subjected to a pretreatment and examined for the roughness of the stratum corneum by an electron microscope. The result of the group using the product containing glacier water was compared with that of the group using the product without containing glacier water and it was confirmed that the product containing glacier water had the effect of soothing the skin. The result is shown in FIG. 7 to FIG. 10.
From the results of FIG. 7 to FIG. 10, it was noted that Formulations 2 and 3 reduced the roughness of the stratum corneum much more than Comparative Formulations 4 and 5 and thus, the products containing glacier water were more effective in soothing the skin.
