Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition for whitening and manufacturing method,

The present invention relates to a whitening cosmetic composition and a method for preparing the same, and more particularly, to a cosmetic composition which has excellent whitening effect but does not have side effects using a boat extract and a method for producing the same.

The skin is the largest organ of the body, always in direct contact with the external environment, and serves as a protective layer for protecting the living body from various stimuli or dry environment. It is an organ where new cells are generated and eliminated extensively as compared with other organs. In addition, it protects the body from physical abrasion, protects the inside of the body from moisture loss, protects it from ultraviolet rays generated from the sun, and plays a very important role in controlling body temperature.

Such skin causes skin problems such as skin contamination, drying, trouble, pigmentation due to various physical factors, external environmental factors, and infections, and eventually causes dermatitis, allergy and deterioration.

These skin tissues are roughly divided into three parts: epidermis, dermis and subcutaneous tissue. The skin color of a person varies depending on the number, size, type and distribution of melanosomes containing melanin mainly contained in skin cells. Melanomas are produced by melanocytes, and melanin is a black pigment produced in the epidermis and produced in cells called melanocytes.

Melanin absorbs ultraviolet light energy in sunlight and protects deeper cells from damage by ultraviolet light. However, abnormal production of melanin causes skin lesions such as vitiligo. On the other hand, excessive synthesis of melanin due to ultraviolet rays causes not only damage to the skin but also formation of spots and freckles, leading to skin cancer do.

Several factors are involved in determining the skin color of a person. Among them, factors such as the activity of the melanocyte making the melanin pigment, the distribution of the blood vessel, the thickness of the skin, and the presence or absence of the pigment inside and outside the body such as carotenoid and bilirubin are important. In particular, the most important factor is melanin, a melanin pigment produced by the action of various enzymes such as tyrosinase in melanocytes in the human body. The formation of melanin pigment affects genetic factors, hormonal secretion, physiological factors such as stress, and environmental factors such as ultraviolet irradiation.

However, excessive formation and deposition of melanin pigment causes skin diseases such as darkening of skin, stain, freckles, pigmentation deposition, and so on. Accordingly, in order to treat or alleviate excessive melanin pigmentation caused by exposure to ultraviolet rays or the like, substances having ascorbic acid, kojic acid, arbutin, hydroquinone, glutathione or derivatives thereof and tyrosinase inhibiting activity have been previously used as cosmetic or pharmaceutical products But they are limited in their use due to insufficient whitening effect, stability to the skin, formulation and stability in combination with cosmetics, and the like.

In recent years, studies have been continued to find whitening active ingredients in natural products, and the fact that many plant extracts such as mulberry (Korean Patent Publication No. 99-002109, No. 97-021273) act on tyrosinase and inhibit melanin production However, these are also problematic in that they are used in cosmetics or medicines in excess of the effective concentration in terms of stability, safety, and discoloration possibility, and they are not satisfactory.

Particularly, when these whitening compositions are used in combination with cosmetic packs, the skin is kept in direct contact with the skin for a certain period of time due to the characteristics of the pack, so that the effect of damaging fragile skin or regenerating the skin with healthy, The cosmetic pack composition has the disadvantage that severe side effects such as skin rash and allergies can be caused.

It is an object of the present invention to provide a cosmetic composition which has high skin whitening effect and does not adversely affect the skin, using a pear extract, and a method for producing the same.

In order to attain the above object, the whitening cosmetic composition of the present invention is characterized by containing a pear extract and a layered flower extract.

The pear extract is characterized in that the pear extract is extracted by adding at least one extraction solvent selected from water, a lower alcohol having 1 to 4 carbon atoms, a polyhydric alcohol or a mixture thereof.

The layered flower extract is characterized in that the layer is a fermentation broth obtained by fermenting flowers.

To achieve the above object, the present invention provides a method for producing a whitening cosmetic composition, comprising the steps of: extracting a pear extract and a layered flower extract; The extract of the present invention and the layer extract of the present invention are added in an amount of 0.1 to 20% by weight based on the total weight of the composition, and the extract of the present invention can be used as a lotion, cream, essence, pack, makeup base, foundation oil, body lotion, A hair cleansing foam, a hair oil, a hair shampoo, and a hair rinse.

The layer extract of the layer extract of the extracting step is characterized in that yeast is added to the layered flower and then fermented at 20 to 40 ° C for 30 to 60 days.

As described above, the present invention can be effectively used for patients having skin sensitive or skin diseases because it contains natural substances such as a pear extract and a layered flower extract,

In addition, the present invention has excellent skin whitening effect by reducing skin pigmentation.

Hereinafter, a whitening cosmetic composition according to a preferred embodiment of the present invention and a method for producing the same will be described in detail.
