Description

Astringent Cosmetic Composition Comprising the Extract from the Fruit of Poncirus trifoliata as Active Ingredient}

The present invention relates to a convergent cosmetic composition.

In general, cosmetics are aimed at the aesthetic function to clean human skin or express beautiful and attractive and the defense function to protect the skin from the harmful environment from the outside. This role of the skin declines due to various harmful environments (increase in ultraviolet radiation, air pollution, stress and irregular eating, etc.), cosmetics are caused by the reactive reactive oxygen, free radicals and peroxides caused by these harmful factors It not only improves the various problems of the skin, but also protects the skin and helps the skin to maintain its normal function.

One of the functions of maintaining healthy skin by skin protection of cosmetics is a convergence action. The astringent effect of cosmetics means to make skin feel elasticity and suppleness by contracting excessively opened pores or pores. Contraction of the skin has a physical and chemical action. The physical action is to temporarily reduce the surface temperature of the skin by the heat of evaporation when the alcohol contained in the lotion evaporates, constricting pores and pores where sebum is secreted, and converging effect, and the chemical action is the coagulation effect of acid or protein. Coagulates and contracts proteins in the secretory areas of sebaceous glands and sweat glands by a substance with astringent effect.

In general, astringents that have a convergence effect are used in the preparation of a lotion. The action of the cosmetics having a convergence effect on the skin is, firstly, to keep the skin weakly acidic, and secondly to prevent skin troubles by inhibiting the development of microorganisms, and thirdly to convergence. By suppressing sweating by the action to prevent the makeup to rise.

When astringents are applied to the skin, the effect on the skin is local. The effect of astringents is on the upright hair, tight skin (at least the skin feels tight), temporary shrinkage of pores or pores, suppression of sweating, relief of oily skin, blood coagulation of wounds, wound healing and tissue growth Promotion. Due to these many advantages, a substance having a convergence effect is recognized as an important ingredient in cosmetics.

Astringents are largely divided into cationic and anionic ones. Cationic astringents include allantoin hydroxyaluminum, allantoin dihydroxyaluminum, lead chloride, aluminum chloride, ferric chloride, zinc oxide and aluminum lactic acid. Zeros include citric acid, tartaric acid, tannic acid, lactic acid and malic acid.

Chemically convergent astringents are classified into two groups. First, metal ions that converge with organic or inorganic acid salts include iron, chromium, aluminum, zinc, lead, mercury, tin, copper, silver, and zirconium. There is a convergence effect by lowering the activity of the Hansen. The convergence effect by the metal salt is different depending on the kind of metal and the kind of anion in the salt compound, and the effect is also not high. In addition, metal ions other than zinc, aluminum, and zirconium are toxic, discolored, and irritated with skin, which is not preferable for cosmetics. Second, citric acid and lactic acid are the most commonly used low molecular weight organic acids. Third is lower alcohol. These astringents generally have the effect of precipitating proteins, causing the skin to shrink and give astringent effect.

Recently, plant extracts having astringent effects have been developed as astringents in accordance with the trend of natural cosmetics. A typical example is the witch hazel extract, which has excellent color and stability, but the convergence effect is insignificant. In addition, zinc parasulfonic acid, tannin, tannic acid and the like has an excellent astringent effect and excellent solubility, but its use is limited because of its low stability when applied to cosmetic formulations and concerns about skin irritation.

Thus, the present inventors have completed the present invention by confirming that the convergence effect of the fruit extracts obtained from the fruit of Tangerine fruit is very excellent as a result of repeated studies to overcome the problems of the existing cosmetic composition with a small convergence effect.

Accordingly, it is an object of the present invention to provide a convergent cosmetic composition containing fruit extract as an active ingredient.

Other objects and advantages of the present invention will become apparent from the following detailed description and claims.

According to one aspect of the present invention, the present invention provides a convergent cosmetic composition containing a fruit extract as an active ingredient.

In the cosmetic composition of the present invention, the fruit ingredient ( Ji ) is an unripe fruit of the Poncirus trifoliata ( Poncirus trifoliata ). Being mature is called perception.

Tanga trees grow 3-4 m high, and flowers bloom in white 1-2 at the end of stem or axilla before leaves in May. Fruits are berry, round and yellow, ripen in September, with good fragrance, but cannot be eaten. In the room, the chamber is used for the treatment of stomach dyspepsia, abdominal swelling, frequent belching, abdominal pain, etc., while leading strongly to the circumcision of the stomach. The symptoms of heartburn due to coronary artery disorders are used in combination with whitening and fruiting.

The basement contains aromatic essential oils and flavonoids. Perception, perception show the action of heart and blood pressure. Perilla and perceptual decoction have an inhibitory effect on the intestinal smooth muscle of various animals, which is used in the stomach, sewage, gastric dilatation, intracolonial fluid and disinfection. Gastrointestinal excitement, peristalsis enhancement, etc. are beneficial to restore gastrointestinal dysfunction. The uterine excitability of the rabbit is remarkable, diuretic and antiallergic. It is also effective as a medicinal acupuncture agent for cardiac breakdown.
