Description

(WHITENING COSMETICS COMPOSITION) having skin whitening and wrinkle improving activity,

The present invention relates to a cosmetic composition having skin whitening and wrinkle improving activity, and more particularly, to a cosmetic composition having an excellent effect on skin whitening effect by providing melanin inhibitory activity, preventing skin aging and improving wrinkles will be.

Skin is the largest organ in the human body and its area is about 1.6m2 in size. It is a large organ which weighs 16% of body weight. Skin is the most basic covering covering the body to protect internal organs. It is also a very important institution that performs many functions.

Skin melanogenesis is a defense mechanism against stimuli such as ultraviolet light in melanocyte-producing cells (melanocyte), and a large amount of melanin produced by the melanin is transferred to keratinocyte and accumulated on the skin surface layer Results. Although melanin protects the skin, hyperpigmentation of the skin causes skin irritation, freckles, darkening of the skin after inflammation of the skin and aging pigmentation spots. This causes the discomfort of the person not only the cosmetic discomfort but also the psychological negative affect on the social activities. . Melanin is produced by tyrosine tyrosine, an enzyme called tyrosinase, converted into DOPA or dopaquinone, and then enzymatically oxidized to form an abnormal deposit in the skin And it is known that it produces spots and black spots. Materials for inhibiting melanin production such as hydroquinone, arbutin, vitamin C and derivatives thereof have been developed for the relief, prevention and treatment of such pigment deposits, stains and spots, and whitening cosmetics containing them have been disclosed And Korean Patent Publication No. 2005-0509848 discloses a whitening cosmetic composition containing a keractone derivative isolated from Korean Patent Publication No. 2005-0509848. Korean Patent Publication No. 2005-0479741 discloses a whitening cosmetic containing a glucose acylated derivative. Of these, hydroquinone is generally recognized for its effectiveness, but is generally limited in its use because of its sensitivity.

On the other hand, the skin of the human being is exposed to chemical and physical stimuli of the outside, the normal function of the skin is deteriorated and problems are caused, and the aging phenomenon of the skin is promoted and the skin is damaged. Skin wrinkles are one of the aging of such skin. Generally, it is known that skin wrinkles are generated by a complex action of various factors such as moisture content of skin, collagen content and immunity against external environment. Among these factors, collagenase, which is the collagenase which decreases collagen production and collagen content, has the greatest influence on the formation of wrinkles.

Various compositions have been conventionally used to inhibit whitening and wrinkling of the skin as described above. For example, various extracts extracted from L-ascorbic acid and its derivatives, hydroquinone, arbutin, licorice, and bark extract are used as skin lightening agents and wrinkle removers. However, L-ascorbic acid is easily oxidized to cause irritation to the skin. The cosmetic composition containing the L-ascorbic acid causes discoloration and irregularity, and the substances derived from the plant extract have a strong effect on the homogeneity of the product And arbutin has a disadvantage in that the effect is low.

As shown in Table 4, the cosmetics of formulations 1 to 3 containing the substances of the present invention showed a superior skin whitening effect as compared with conventional cosmetics.

[Experimental Example 1] Measurement of inhibitory effect on melanin formation

The whitening effect at the cellular level was investigated by adding the extract of Liliaceae, Rhizopus japonicus, Lycopersicon esculentum and Persimmon Leaf to the culture medium of rat melanoma cells (B-16 mouse melanoma cell) (Lotan R., Lotan D. Cancer Res , ≪ / RTI > 40 , pp. 3345-3350, 1980). The resulting compounds were added to the culture medium of B-16 melanoma cells so as to have a final concentration of 5 / / ml and 15 / / ml, respectively. After culturing for 3 days, the cells were treated with trypsin Melanin was extracted after centrifugation from the container. Was added 1 N sodium hydroxide solution, 1ml the extract dissolved melanin boiled for 10 minutes, using a spectrophotometer 475 nanometers (nm) in the amount of the produced melanin unit cell allowance by measuring the absorbance at (10 ⁶ cell) absorbance (Repeated three times). The relative amount of melanin production relative to the control group was calculated as the inhibition rate (%), and the results are shown in Table 5.

Inhibition of melanin formation at the cellular level sample Concentration (ug / ml) Inhibition rate (%) Control group - - Germ extract
1.0 15 10.0 58 Horsetail extract 1.0 11 10.0 43 Carrot extract 1.0 8 10.0 36 Persimmon leaf extract 1.0 12 10.0 40

As described above, it was confirmed that the whitish extract, the whitetoptera extract, the camel root extract, and the persimmon leaf extract according to the present invention have an effect of inhibiting melanin formation, and thus, the whitening cosmetic composition is effective.

[Experimental Example 2] Wrinkle-improving effect test

The effect of wrinkle improvement can be generally measured as collagen biosynthesis performance, collagenase degradation inhibition ability, and human clinical test. Human normal fibroblasts were inoculated into 6-well microplates containing DMEM medium

(2 × 10 ⁵ cells / well) in a 5% CO ₂ incubator at 37 ° C. for 24 hours. After 24 hours, the medium was removed from each well, samples were treated at different concentrations, and then cultured again for 24 hours. After 24 hours, the cell culture medium was collected to prepare a sample. The amount of collagen synthesis was measured by using a procollagen type I C-peptide (type I C-peptide) in a cell culture medium using a collagen measurement kit (Procollagen type I C-peptide EIA kit (MK101), Takara, : PICP) was measured and analyzed. An antibody against collagenase was used as a method for measuring the activity of collagenase degrading collagen. The collagenase activity was measured using a Type I collagenase assay kit (Amersham Biosciences, RPN2629) and the absorbance was measured with an ELISA reader. The measured values were expressed as mean ± standard deviation, and the significance was tested by t-test using the SPSS / PC + program. The results are shown in Table 6 below.

sample Increase in collagen synthesis (%) Collagenase inhibition rate (%) Four kinds of mixed extracts of Example 1
(Concentration of each extract 1 占 퐂 / ml) 18 11 Four kinds of mixed extracts of Example 1
(Concentration of each extract 5 / / ml) 39 19 Four kinds of mixed extracts of Example 1
(Concentration of each extract was 10 占 퐂 / ml) 42 28

As shown in Table 6, the composition according to the present invention increased collagen synthesis in a concentration-dependent manner and inhibited collagenase activity in a concentration-dependent manner. Therefore, the composition according to the present invention has a wrinkle-reducing effect.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims. It can be understood that
