Oolong tea component containing a cosmetic composition having a slimming effect according to the present invention can be prepared by the following method.

1 is a process diagram schematically showing a manufacturing process of an oolong tea component-containing cosmetic composition excellent in the slimming effect according to the present invention.

Referring to Figure 1, the step of extracting gotucola component by the solvent extraction method with ethyl alcohol (S11), extracting alginic acid from seaweed (S12); Separating the tannin or polyphenol component from the oolong tea (S13), mixing with the base or functional ingredients (S14) and the step of making an ointment, cream, lotion or lotion shape (S15).

Goto Kola can be extracted from the leaves and roots of the Gotu-Cola tree, which is a perennial vine plant belonging to the Apiaceae family native to regions such as India, Japan, China, Indonesia, Sri Lanka, South Africa, and the South Pacific. The main ingredient of gotucola is triterpenoids, which are composed of Asiaticoside, Madecasoside, Asiatic acid or Madecassic acid. In addition, Gotu-Cola contains ingredients such as vitamin K, magnesium, calcium or sodium.

Such gotuola can be obtained through solvent extraction. Specifically, the stem or leaves of the gotu-cola tree are harvested, dried in the shade, and then soaked in 30-50% ethyl alcohol for 2-4 weeks. After applying a high pressure of 2 to 5 atm to extract the solution from the ethyl alcohol solution and primarily extract the main components. After that, the stems or leaves of the dried gotu-cola tree were added to the first extraction solution in the same amount as the amount introduced in the first extraction process and soaked for 2-4 weeks. Thereafter, a second extraction solution is obtained through the same process as that of obtaining the first extraction solution. As such, the components extracted through the secondary extraction process include 30 to 35 wt% of Asianticoside, 25 to 35 wt% of Asiantic acid and 0.5 to 5 wt% of Madecassoside.

Once the gotucola component is extracted (S11), alginic acid is extracted from the algae (S12). In order to extract alginic acid from algae, seaweeds such as seaweed, Ecklonia cava, 톳, Mabanban or kelp are harvested and washed with water. Then, the algae washed with sulfuric acid is pretreated and added to NaOH, NaHCO and Na ₂ CO ₃ solution and maintained at room temperature for 3 to 12 hours. The solution can then be filtered to extract alginic acid. The method for extracting alginic acid shown is exemplary and the alginic acid may be extracted by any method known in the art and the present invention is not limited thereto. Alginic acid, also known as seaweed, is a polymer of two uronic acids and corresponds to a compound with a degree of polymerization of 80 and a molecular weight of about 1,500. According to the present invention, the alginic acid may be a natural alginic acid derived from algae extracted from brown seaweed, seaweed, kelp, maban, or 톳 as described above. Alginic acid has a 1,4-glycosidic bond between manuronic acid and gluronic acid, in which the hydroxyl group of mannose has a carboxyl group, and binds to a divalent metal ion. This may have a function of removing heavy metal contaminants added to the cosmetic composition and attached to the skin.

Once the alginic acid is extracted (S12), tannin or polyphenol may be separated from the oolong tea. Tannin refers to an aromatic compound having a plurality of phenolic hydroxy, and polyphenol refers to a compound having two or more hydroxy groups and containing a substance such as catechins.

Oolong tea is a semi-fermented tea with the intermediate properties of green tea and black tea. Generally, tea leaves are collected in the spring and summer to make oolong tea, which is then wilted in the sun. After the moisture is removed and fermented for some time, oolong tea can be made by making the enzyme stop working. When oolong tea is made, the components to be added to the cosmetic composition according to the present invention may be extracted. The polyphenol component contained in oolong tea is made from polybanol. One of the other components of oolong tea is catechins belonging to flavan-3-ols of the flavonoid group. Catechins include free catechins, ester catechins and bound catechins and have antibacterial, detoxification, antioxidant and free radical elimination functions. In the cosmetic composition according to the present invention, the amount of catechin may be suitably adjusted by the degree of fermentation.

Any method known in the art may be used to extract the polyphenol component including catechin from oolong tea, but preferably the polyphenol component may be extracted according to the following method.

In order to extract the active ingredient from oolong tea, the leaves of the harvested tea are left in the sun for 20-30 minutes. After drying in the shade while maintaining a temperature of 15 ~ 20 ℃ to make the moisture content of 60 ~ 70 wt%. Fermentation of tea leaves means that the polyphenols contained in tea leaves are oxidized by polyphenol oxidase, so that polyphenols such as tea red pigment (TF), tea sulfur (TR), or tea brown (TB) are soluble. The process of becoming an oxide. Fermentation herein refers to the oxidation of such polyphenols. When the moisture content is between 60 and 70 wt%, the leaves of the tea are moved to the steam room. Then, steam is sprayed on the leaves of the tea for 20-50 seconds while maintaining the temperature of the steam chamber at 90-110 ℃. The polyphenol component can be extracted by hot water extraction or solvent extraction from the leaves of the tea whose oxidation or fermentation has been stopped by spraying steam. For example, oolong tea can be immersed in distilled water at 85-90 ° C. for hot water extraction and maintained for 20-30 hours. According to the present invention, hot water extraction may be performed under reduced pressure. Specifically, oolong tea may be hot water extracted at a pressure of 300 to 500 mmHg for reduced pressure hot water extraction. Extraction solution according to reduced pressure hot water extraction is filtered and concentrated by a rotary evaporator (rotary evaporator). The concentrated extraction solution may then be stored frozen at a temperature of -20 ~ -10 ℃.

When the polyphenol component is separated (S13), the extracted polyphenol component may be mixed with the base component of the cosmetic along with the extracted gotucola component and alginic acid component (S14). The gotucola component, the alginic acid component and the polyphenol component can be mixed with the base component in the form of a liquid. For example, the polyphenol, gotucola and algiic acid components can be mixed with cetanol, glycerin or stearyl alcohol. In addition, the oolong tea component-containing cosmetic composition having a slimming effect according to the present invention may include various functional ingredients. For example, the oolong tea ingredient-containing cosmetic composition excellent in the slimming effect according to the present invention may include a nutrient ingredient such as a sunscreen, collagen ingredient, whitening ingredient or ginseng extract.

The high tucola component, the alginic acid component and the polyphenol component may be composed of 3 to 8 wt%, 2 to 5 wt% and 0.1 to 1.0 wt%, respectively. If each component is added less than a predetermined amount has a problem that the practical effect is difficult to appear. In addition, when the gotucola component exceeds 8 wt%, the saponin component is difficult to disperse sufficiently, and when the polyphenol component exceeds 5 wt%, it may inhibit the absorption of other components, and when the alginic acid component exceeds 1.0 wt%, the remaining amount There is a problem that this may be precipitation.
