Cosmetic composition for pore reduction and sebum secretion containing pomegranate and centilla asiatica extract {Cosmetic Composition for the Pore-minimizing and Inhibition of Sebum Secretion Containing the Extracts of the Punica Granatum and Centella asiatica}

The present invention relates to a cosmetic composition, and more particularly, a mixed extract of pomegranate extract and centella as a cosmetic having excellent pore reduction effect by inhibiting sebum secretion, promoting collagen synthesis, and removing sebum and wastes in pores. It relates to a cosmetic composition comprising% to 10%.

The present invention relates to a cosmetic composition, and more particularly, a mixed extract of pomegranate extract and centella as a cosmetic having excellent pore reduction effect by inhibiting sebum secretion, promoting collagen synthesis, and removing sebum and wastes in pores. It relates to a cosmetic composition comprising% to 10%.

In general, cosmetics are applied to the skin to clean, protect or beautify the skin and have a slight effect. For this purpose, cosmetics are used in various forms such as lotion, emulsion, cream, essence and foundation. It is used. The biggest changes in facial skin caused by aging have been known as wrinkles, decreased elasticity and dryness, and most skin researchers or cosmetics companies are focusing on research and product development.

  Skin is classified into various types such as dry, neutral, oily or complex depending on the condition of the skin surface, which is determined by the amount of natural moisturing factor (NMF) and sebum. When the balance of NMF and sebum is well balanced, the skin stays moist and soft. On the other hand, too much sebum secretion is likely to be oily skin or acne skin. Oily skin, because the pores of the skin comes to the surface of the skin surface with a lot of sebum secretion and pores are present, the face looks dirty and makeup is easily erased. Accordingly, attention has been focused on the function of overcoming these problems to alleviate the discomfort of the skin sebum secretion, refreshing the skin and reducing skin irritation.

  The dermis consists of connective tissue beneath the epidermis, filled with a network of macromolecules called extracellular matrices. Part of the extracellular matrix is the fibrous protein of polysaccharides, collagen and elastin, called glycosaminoglycans or mucopolysaccharides. Among them, collagen is a major protein of extracellular matrix, which is responsible for maintaining tissue morphology. The dermis has a great impact on the elasticity and tension of the skin. Therefore, if collagen is damaged by external or internal influences, wrinkles may occur or skin elasticity may be reduced, resulting in skin sagging. This is why recent antiwrinkle cosmetics use ingredients that increase collagen synthesis, such as retinol. In addition, the size of pores is a phenomenon in which the matrix structure of the dermis is relaxed and the skin around the pores is stretched. The dermis contains blood vessels, nerves, hairs, hair roots (also called brushed muscles), sweat glands, and sebaceous glands. The sebaceous glands constantly produce sebum and secrete sebum on the skin surface through the pores from the sebaceous gland drainage tube. At this time, the pores tend to be keratinized (delayed departure due to inconsistent keratinization), and the thickened stratum corneum peels into the hair follicles, clogging the pores, leaving sebum in the hair follicles, causing rashes, inflammation, and forming granulomas, leaving behind traces. do. Therefore, in order to effectively reduce the enlarged pores, keratin of the pores thickened by abnormal keratinization process should be removed to activate cell metabolism and promote collagen production from the dermal tissue to restore the structure of the recessed or sagging pores.

The main component of the pomegranate extract used in the present invention is about 40% of sugar (glucose, fructose) and about 1.5% of citric acid , which has a sour taste as an organic acid . It also contains water-soluble vitamins (B1, B2, niacin), but in small amounts. The shell contains tannins and seeds contain natural plant estrogens, which are good for menopausal disorders . It is very effective when dysentery, volatile alkaloids are used as parasites, especially tapeworm remedy. Fruit juices are used to make drinks and sweets by dipping fruit juices and making concentrated juices . It can also be mixed with olive oil to make a good constipation oil.

  Centila asiatica extract used in the present invention is a perennial plant belonging to the family Apiaceae also called horseshoe grass and clam grass. In India, it has been used for long time in the treatment of leprosy, and in Taiwan, it is used as an antipyretic agent for fever of fisherman's fever or when poisoned by snake bites, and it is very effective under the hundreds of women. According to recent experimental reports, the antimicrobial activity of tuberculosis bacteria is reported to be large. The definition of centilla asiatica in cosmetics is the ingredient madecaic acid, which has been spotlighted as a skin regeneration effect in modern medicine, and has an excellent effect on wound healing and blood circulation.

The present invention has been completed to solve the above problems by focusing on shrinkage of pores and reducing sebum secretion while developing a pore-reducing cosmetic having excellent practical effects without causing side effects on the skin. Therefore, it promotes collagen production of dermis matrix with centila asiatic acid, while restoring the structure of pores impregnated with pomegranate extract with excellent anti-tumor effect and skin cell proliferation, thereby fundamentally reducing the size of enlarged pores or preventing the increase of pore size. It is to provide a cosmetic composition aimed at.

In order to achieve the above object, the pomegranate extract and the cosmetic composition for inhibiting sebum secretion according to the present invention is a cosmetic composition for inhibiting sebum secretion by pore contraction as a pomegranate and centila asiatica mixed extract as a whole It is characterized by containing 0.01 to 10% of the composition.

  Natural products are excellent in their function, have many active ingredients, have little toxicity, and have many advantages of natural lighting. The inventors of the present inventors examined materials useful for inhibiting sebum secretion and controlling oily skin, and found that pomegranate and centilla asiatica have excellent astringent activity.

  Method for producing a mixture of pomegranate and centila asiatica extract according to the present invention is as follows.

At least one solvent selected from the group consisting of general purified water, ultrapure purified water, hydrous butylene glycol, hydrous ethanol, hydrous propylene glycol, and hydrous glycerin as an extraction solvent in pomegranate and centilla asiatica is added to To 20 times after extraction. The extraction method is a method of extracting by heating for 10 to 20 hours at 80 to 95 ℃ or by extracting the active ingredient at 15 to 35 ℃ for 10 to 20 hours in a state in which the cooling condenser is attached to prevent the solvent from evaporating Can be. The pomegranate and centila asiatica mixed extract thus obtained are concentrated under reduced pressure while recovering the solvent evaporated using a distillation apparatus equipped with a cooling condenser, and then added to the cosmetics in an amount of 0.01 to 10% of the total composition by dry weight thereof.

 The pomegranate contained in the cosmetic according to the present invention is a fruit of a pomegranate whose scientific name is Punica Granatum, and the pomegranate is a fruit having a round shape with a diameter of 6-8 cm. It is covered with hard yellowish skin and there are many seeds in the pulp. You can eat about 20% of the flesh, but the sweet and sour taste and the timidity is used as a medicine.
