Generally, ultraviolet rays included in the sun's rays are divided into long, medium, and short wavelengths according to their wavelength ranges. These ultraviolet rays are known to cause various side effects on the skin.

Short wavelength ultraviolet rays in ultraviolet light are very harmful to the human body, but until now they are absorbed by the ozone layer in the atmosphere and hardly reach the earth's surface. Medium-wavelength ultraviolet rays, which cause photoallergy and more energy, cause erythema, blistering, burns, skin cancer, pigmentation, and degeneration of skin proteins. Importantly, various sunscreens have been developed to block ultraviolet rays.

Conventional ultraviolet absorbers include compounds such as benzophenone derivatives, paraamino derivatives, cinnamic acid derivatives and triazine derivatives, and inorganic pigments such as titanium dioxide and zinc oxide have been used as ultraviolet scatterers. It absorbs only the ultraviolet rays of the intestinal ultraviolet region and is a chemical synthetic substance, which is likely to cause other side effects on the skin, such as irritation and allergy. In addition, UV scattering agent is opaque when used as a cosmetic in addition to ultraviolet light as well as visible light has been pointed out that the feeling is poor when applied to the skin.

On the other hand, a substance having an ultraviolet absorbing action extracted from a natural product generally has a low irritation, and has other pharmacological actions such as anti-inflammatory, astringent, and antimicrobial effects, and thus has been promising as a ultraviolet absorber conventionally incorporated into cosmetics. Efforts have been made to search for and isolate ultraviolet absorbers contained in natural products.

The present invention is to solve the above problems, as a part of the research to overcome the disadvantages of the known sunscreen and to develop a better sunscreen considering the characteristics of the herbal extract extracted with water or organic solvent from various natural products As a result, while researching to develop a cosmetic composition having a skin soothing effect, it contains a main herbal plant, that is, magnolia, sandflower, lotus, balsam, azalea extract to provide a cosmetic composition with excellent skin soothing effect.

It is used in combination at a ratio of ˜30% by weight.

Distilled water of 1 to 10 times was added to the herbal extracts mixed in the above compounding ratio, and extracted three times for 6 hours at 100 ± 10 ° C., filtered, concentrated under reduced pressure, and added to prepare cosmetics.

The cosmetic composition according to the present invention is characterized in that it contains 0.1 to 5% by weight of the prepared herbal extract to preferably 1% by weight.

Cosmetic compositions having a skin soothing effect according to the present invention may have a conventional formulation, for example, may be formulated with softening water, astringent makeup, nutrient cosmetics, nutrition cream, body lotion, body oil, body essence and the like. .
