Description

The present invention relates to a cosmetic composition containing indigo extract,

The present invention relates to a cosmetic composition using a side extract.

(Scientific name: polygonum indigo) is a year-old herbaceous plant of the dicotyledonous plant Pyralidae. It originated in China and was cultivated in the past as a dye resource. The stem is straight and has a height of 50 ~ 60cm and a purplish red color. The fruit is an achene, wrapped in a calyx, three ovate egg shape, 2mm long and blackish brown. Leaves are used as indigo dye. In addition, the side includes indikans for producing indigo used for preparing dyestuff dyes, and the indigo is used for the preparation of dyes for side dyeing, and includes cymbidium, In Japan, the cradle is thought not only to be used for the preparation of dyes but also to contain useful physiologically active ingredients for the leaves and fruits. The leaf and fruit are obtained by drying in the sun, The fruit is used as a herbal medicine. Further, in recent years, antitumor activity, antiviral activity, antimicrobial activity, and the like, which contain the extract of Aspergillus, have been studied.

On the other hand, the skin covers the entire surface of the body, protects the internal organs from the external environment and stimulation, and plays an important function as a barrier to inhibit moisture evaporation and to prevent the penetration of foreign substances from the outside. However, the skin is always exposed directly to the external environment. As the ozone layer is exposed to ultraviolet radiation, stress, toxic chemicals, etc., skin keratinocyte and fibroblast activity are reduced, and collagen synthesis It is sensitive to external stimuli due to decreased ability and elastin synthesis ability, decreased water holding capacity, increased dry skin, and reduced ability to defend against external infectious agents. In recent years, there have been a growing number of people who complain of skin troubles such as erythema, edema, acne and itch, thereby reducing the skin irritation caused by various irritant sources, and in particular, a lot of synthetic surfactants contained in detergents and cosmetics It has been urgently required to develop a skin irritation mitigating substance which can reduce skin irritation due to use and thereby reduce the skin side effects of modern people.

In general, many skin-related products often contain substances that can cause skin troubles such as irritation, inflammation, allergies, etc., and more than 10% of people using personal care products have side effects In the US in the 1990s, more than 50% of consumers thought of themselves as sensitive skin. Moreover, recent cosmetics tend to concentrate on functional cosmetics that can give a real effect to the skin, and skin side effects caused by the use of personal care products such as cosmetics are expected to increase more and more.

Factors that increase the rate of feeling sensitive skin include the increase of ultraviolet radiation dose due to destruction of the ozone layer, drying of living space, personal allergy, stress, and increase of chemical harmful substances. On the other hand, It is presumed that this natural-friendly, low-level stimulation is also contributing to the awareness of sensitive skin. Therefore, there is a growing interest in materials that alleviate the stimulation of cosmetics.

To make cosmetics, various raw materials are used and usually 20 to 50 kinds of raw materials are used. These ingredients have been proven to be safe through skin irritation tests, but they can also cause skin irritations such as irritation, itching and allergies by being applied to products. These reactions do not happen to everyone, and they can only happen to certain people.

Conventionally, various methods for alleviating skin irritation have been attempted. For example, a method of removing a substance causing skin irritation has been attempted. However, such a study is limited because the functional raw material itself acts as a stimulus source. For example, lactic acid, glycolic acid, salicylic acid, and retinoid are contained in cosmetics for the promotion of skin cell regeneration or anti-wrinkle effect, but they cause skin irritation do. Recently, many studies have been made to neutralize the acidity by adding strong alkali such as NaOH or KOH to the stimulant-inducing functional raw material to alleviate the irritation, but such a prescription has a problem of deteriorating the efficacy of the existing raw materials.

Recently, studies have been carried out on inhibition of cell-mediated immunity. Neuropepetides such as calcitonin gene-related peptide (CGRP) and substance P (sunstance P) secreted from neurons, Various cytokines and PGE2 in skin and immune cells, such as kinins such as bradykinin, activated by stress in tissue or plasma, are involved in edema formation and vasodilation, It has been known that it acts as a cause. Neuropeptide antagonists including substance P, bradykinin antagonists and COX inhibitors have been proposed as substances capable of reducing skin irritation and irritation. (Korean Patent Publication No. 2000-0058730), raspberry leaf or heat Skin external composition containing the extract (Republic of Korea Patent Publication No. 2003-0015654 call), a cosmetic composition containing a phytosterol (Patent Publication No. 2002-0063987), etc., but did not indicate a clear effect.
