Description

TECHNICAL FIELD The present invention relates to a cosmetic composition for skin whitening containing a fermented extract of Cheongmiljil and a method for producing the same,

The present invention relates to a cosmetic composition for skin whitening containing a browning room fermented extract and a method for producing the same.

In particular, the present invention is based on the fact that various phytogenic organic acid components of Cheongpilmil extract are more safe and effective than peptides of AHA and BHA in peeling keratin composed of dead cells of skin, To a cosmetic composition for skin whitening and a method for producing the same.

Skin is the largest organ of the human body that protects our body from external stimuli. It has barrier function to prevent the internal moisture and oil components from flowing out of the skin, temperature control function, excretion function, sensation Function, and respiration function.

The skin is composed of the epidermis, the dermis and the subcutaneous fat layer, and the epidermis which is the outermost layer of the skin functions to protect the skin from the external environment.

On the other hand, the keratinized dead cells on the outermost layer of the epidermis function as a skin barrier with the help of the cement function such as intercellular lipids, and accumulate abnormally excessively to make rough and dull skin texture, In addition to cosmetic problems such as skin color not appearing to be glazed and fading, skin aging, wrinkle formation, and dryness of the skin may cause skin health impairment.

The epidermis is divided into the basal layer, the superficial layer, the granular layer, the transparent layer, and the stratum corneum. The keratinocytes are made from the basal layer and disappear from the stratum corneum of the outermost layer, disappearing every 28 days, .

In addition, as the cells constituting the epidermal layer, there are various cells such as keratinocytes, Rangelans cells, Merkel cells and melanocytes, and keratinocytes are the cells that occupy most of them. The keratinocytes undergo cell proliferation in the basal layer to produce a large number of skin cells, which, in turn, lose their cell life as they pass through the anolyte layer, where the cellular constituents of the inner part are exported out of the cell. Finally, the skin reaches the stratum corneum. However, if there is a problem in the activity of keratinocytes, skin aging, wrinkles and dryness of the skin may occur, resulting in skin sagging, and the elasticity of the skin is lowered. Therefore, it is necessary to activate the keratinocyte which produces the constituent of the epidermal layer of the skin and to improve the function of the stratum corneum to maintain the skin healthy, moisturized and beautiful.

Alpha hydroxy acid (AHA) is a typical substance that promotes keratinocyte keratinization. AHA is a substance widely used as a keratinization promoter, but when a large amount is applied to the skin, it causes not only skin irritation, but also drying of the skin and generation of a transparent layer. Also, formulation of a cosmetic composition containing the AHA has a problem Lt; / RTI >

Many studies have been conducted to develop skin whitening agents from natural products, and some of them have been commercialized as products. The whitening agent has the effect of inhibiting melanin synthesis by inhibiting the blackening process of melanin produced or released from melanocytes or inhibiting the activity of tyrosinase or promoting the reduction of melanin, Return to light melanin.

Melanin is one of the pigments involved in the color of skin, hair and eyes. Melanin is a sulfur compound widely distributed in natural animal and plant systems. It is a neutralized substance having various colors of brown to black depending on the contents of cysteine, glutathione and iron (Fe). It is generally distinguished from alkaline-soluble black melanin and soluble red and yellow melanin.

The plum tree, also called plum tree, is a deciduous broad-leaved arboreous tree of Rosaceae, originating in China and planted with planted trees or fruit trees. The height is 4-5m, the leaves are alternate, egg-shaped, with sawtooth on the edge. A fragrant white or pale pink flower blooms earlier than the leaves in early spring. The fruit is called plum, and it ripens in yellow color in June-July and it is strong in sour taste. The plum has high content of citric acid as its main ingredient, so it can safely exfoliate the skin.

Plum is rich in organic acids such as citric acid, malic acid, succinic acid, tartaric acid, and various minerals as main components. Especially, 60% of plum extract is organic acid centered on citric acid. Such citric acid is a kind of hydroxy acid, which is a compound having an alcoholic hydroxy group at a carbon atom at a position relative to the carboxy group in the molecule. Such compounds are known as effective ingredients for the removal of dry skin, lining, have.

However, the effect on the skin whitening cosmetic composition containing the fermented extract of this browning room has been very limited.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Citric acid and various fruit acids contained in the extract of Cheongpilmil act on the epidermis of the skin to promote exfoliation. However, the inventors of the present application have found that the plums extract When the extract is used as an active ingredient for the whitening effect of the browning room through fermentation using yeast or Kazachstania unispora, the exfoliation effect of the skin keratin, which is formed by dead skin cells, results in the whitening effect ingredient It was confirmed that the penetration into the skin was easy and the skin whitening efficacy could be remarkably increased.

The method of obtaining the extract of the present invention will be described in detail.

The extract of the present invention is prepared by dissolving water having a weight of about 1 to 10 times, preferably about 5 to 10 times the weight of the dried plum powder by a solvent at an extraction temperature of 20 to 60 ° C for about 12 to 24 hours The extract was filtered with a reduced pressure, and the filtered extract was sterilized with a 0.2-μm filter.

After 24 hours, 50 μl of CCK-8 assay solution was added to the cultured cells, and the cells were incubated for 1 hour at 37 ° C. After incubating for 3 hours in a CO2 incubator, check the OD value at the OD450nm wavelength. The OD value and the OD value of the material and the CCK-8 assay solution (by concentration) were used as blank values in a negative control, and the results were shown in FIG. 2 .

(Example 5) cheongmaesil extract, cheongmaesil effect on melanin formation in melanocytes in the fermentation extract

Tyrosinase was purchased from Sigma, and the substrate, L-tyrosine (Sigma), was dissolved in 0.05 M sodium phosphate buffer (pH 6.8) and used as a 0.1 mg / ml solution. The fermented extracts of Cheuremil chamber and Cheongmil chamber were prepared by dissolving in 0.05 M sodium phosphate buffer solution (pH 6.8) by concentration (25, 50, 100, 500, 1000, 1,500 ug / ml) 0.5 ml of L-tyrosine solution was added to a test tube, 0.5 ml of each of the browning room extract, fermented extract concentration (25, 50, 100, 500, 1000, 1,500 ug / ml) was added and left for 10 minutes at 37 ° C.

Thereafter, 0.5 ml of 200 units / ml tyrosinase was added to the sample solution, and the mixture was reacted at 37 ° C for 10 minutes. The reaction tube was placed on ice to quench the reaction, and the absorbance of the reaction tube was measured with a spectrophotometer at a wavelength of 475 nm.

As a negative control, 0.5 ml of a buffer solution was used instead of the above sample, and arbutin, well known as a whitening agent, was used as a positive control.

The inhibition rate of tyrosinase activity of each of the above samples was calculated according to Equation (1).

The inhibitory effect of melanin on the melanin production was investigated at the concentration of 50 ug / ml at the concentration of 25, 50, 100, 500, 1000, 1,500 ug / ml. It was confirmed that the whitening effect was superior to that of arbutin (see Fig. 3).

(Example 6) Confirmation of protein expression involved in melanin formation in melanocytes of a fermented extract of Cheongmilan

The browning room fermented extract was treated with B16F10 murine melanocyte at different concentrations and cultured for 48 hours to confirm the expression of melanin related proteins. MITF, Tyrosinase, TRP1, and TRP2 decreased in the browning room fermentation extract by concentration, indicating that the browning room fermented extract inhibited melanogenesis by inhibiting the expression of proteins involved in melanogenesis.

In addition, a-MSH is known to increase melanin biosynthesis by increasing the production of tyrosinase. Here, we found that the expression of MITF and tyrosinase decreased in the treatment of platelet supernatant and a-MSH, suggesting that platelet supernatant extract directly inhibited tyrosinase activity And inhibit the expression of MITF, tyrosinase, TRP1, TRP2, and other melanin promoting factors, thereby affecting the hypopigmentary effect.

Fermented extracts from Cheongmil chamber inhibit melanogenesis or activate melanin factors (MITF, TRP1, TRP2, Tyrosinase) by activating MEK / Erk signaling. In addition, it activates the Akt signal and suppresses the Wnt / b-catenin signal (signal), thereby decreasing the expression of b-catenin and inhibiting the expression of melanin-related factors.

As a result, it is evident that the browning room fermentation extract inhibits melanin synthesis by inhibiting factors involved in melanin formation and increases whitening efficacy (see FIGS. 4 and 5).
