Description

[TECHNICAL FIELD] The present invention relates to a cosmetic composition containing a desalted lava sea water, a lavender extract, a black bean extract, a pot extract, and a leaf / stem extract. Skin}

The present invention relates to a sensitive skin cosmetic composition having excellent antioxidant, anti-inflammatory and redness-relieving effects, and more particularly to a composition for a sensitive skin cosmetic composition containing desalted lava sea water, lavender extract, black soybean extract, The present invention also relates to a cosmetic composition having an effect of relieving redness by protecting the skin from various stresses and antioxidation, anti-inflammation and atopic dermatitis.

Sensitive skin is a type of skin that reacts sensitively to stimuli. Its symptoms and cause are not clearly known, but it generally responds to external influences such as cosmetics, stress, and air pollution more sensitively than normal skin, It is skin that causes dermatitis well.

The stratum corneum of the skin is the first barrier between the skin and the external environment and is an important determinant of skin condition. The healthy stratum corneum contains 15 ~ 20% of water. When the moisture falls below 10%, the skin becomes dry, the gloss and elasticity are decreased, and the wrinkles are increased. The extrinsic factors such as penetration of irritants and the endogenous factors such as aging, hormones, When defects are caused by factors, the resistance is lowered, resulting in deterioration of the function of the epidermal lipid bilayer and increased sensitivity to stimulants, resulting in sensitive skin and dry skin.

The main symptoms of sensitive skin are redness, obtuse skin, scars, or skin diseases such as contact dermatitis, eczema, and acne. Among these, redness is a phenomenon that the skin gets reddened. It is the most common skin reaction that is caused by various internal or external stimuli.

Reversible reactions in sensitive skin may be followed by inflammatory pathways such as contact irritant salts, allergies, atopy and the like, along the path of allergic reactions. Atopic dermatitis occurs mainly as the content of ceramides in the stratum corneum is decreased. As the water retention function of the stratum corneum is lowered, the skin is dried and a large amount of keratin is produced. As the skin barrier function is lowered, the stimulant- And induce the stimulation, so that the antigen protein which is difficult to intrude into the normal skin invades, and the skin allergy and the like are issued, resulting in severe pruritus.

As mentioned above, it is recommended to use products containing ingredients such as anti-inflammatory, antihistamine, anti-edema, licorice, allantoin, chamomile, etc. to relieve sensitive skin symptoms caused by various causes, There are very few basic data on the treatment and the factors related to the treatment.

This example was intended to prepare lava water for use in cosmetic compositions through desalination. Lava seawater was collected in the eastern part of Jeju Island and the impurities were filtered with a 0.2 μm filter and desalted by an electrodialyzer (ASTOM CO. LTD., Japan) using an ion exchange membrane to remove monovalent ions.

Example 1-2: Preparation of lavender extract, black soybean extract, goat extract and rice leaf / stem extract

Lavender, black soybean, green tea, and rice leaves / stems, respectively, were thoroughly dried and then pulverized to obtain 100 g of each of lavender, black bean, green tea, and rice bran / stem. 1,000 g of each of lavender, black bean, green tea, and rice bran / pulverized product was immersed in a 10-fold volume of ethanol solution (mass concentration of 50 g) for 12 hours at a temperature of 50.degree. Each of the extracts was filtered with filter paper, and the residue was further extracted three times by the same method. Each extract was concentrated under reduced pressure at 50 ?.

Example 1-3: Preparation of the composition according to the present invention

10 to 30 g of the desalted lava sea water prepared above, 50 to 80 g of concentrated lavender extract, 0.01 to 20 g of black soybean extract, 0.01 to 20 g of top extract and 0.01 to 20 g of a rice leaf / stem extract can be mixed. 20g of lava sea water, 60g of lavender extract, 7g of black soybean extract, 7g of candle extract, and 6g of rye / stem extract were mixed.

[Experimental Example 1: Cytotoxicity of the composition of the present invention]

Human fibroblast (CCD-986SK) was cultured in an ATCC (American Type Culture Collection) in order to examine the skin cell survival rate of the composition prepared in Example 1-3. Each cell was inoculated into a 24-well culture plate at a concentration of 1 × 10 ⁴ cells / ml. The medium was DMEM (Dubelco's Modified Eagle Medium, BRL, USA) containing 10% FBS. After culturing for 48 hours in DMEM containing 10% FBS and culturing for 25-30% of the surface area of the culture dish, the cells were further replaced with FBS-free DMEM containing the composition prepared in Example 1-3 and incubated for 24 hours. 50 μl of a solution of 2.5 mg / ml of 3- (4,5-dimethylthiazol-2-yl) -2,5-diphenyltetrazolium bromide (MTT, Sigma M5655, USA) (DMSO, Sigma D2650, USA) solution was added to each well and the mixture was stirred for 20 minutes to dissolve the formed formazan crystals. 100 μl of the solution was added to 96 wells And the absorbance at 570 nm was measured by Enzyme-Linked Immunosorbent Assay (ELISA). The survival rate of skin cells was calculated by the following equation based on the absorbance of the control using pure water and expressed as a percentage. The results are shown in Table 1 below.

The test results of the effect on the cytotoxicity using the human fibroblasts are shown in Table 1 and also shown in the graph in Fig. As shown in FIG. 1, when the composition of the present invention was treated by concentration, it was confirmed that there was no cytotoxicity.

[Experimental Example 2: Antioxidant effect test of the composition of the present invention]

DPPH (2,2-Diphenyl-1-picrylhydrazyl) measurement method was performed to confirm the antioxidant effect of the composition prepared in Example 1-3. The DPPH assay is a method of measuring the absorbance at 540 nm to the extent that the inhibitor decolorizes stable radical DPPH. The used samples are shown in Table 2 below, and the free radical scavenging activity was measured by using the following Equation 2, and is shown in Table 3 and in the graph of FIG.

[Experimental Example 3: Anti-inflammatory effect test of the composition of the present invention]

In order to confirm the anti-inflammatory effect of the compositions prepared according to Examples 1-3, the anti-inflammatory effect was tested by measuring the activity of interleukin-6.

Interleukin-6 is an enzyme that acts as a diverse chemical mediator involved in inflammatory and allergic reactions in vivo, and substances that inhibit interleukin-6 inhibit the production of various chemical mediators. That is, the higher the inhibitory effect of interleukin-6, the better the anti-inflammatory effect. In the present test, the degree of activity of interleukin-6 was measured by using substrate and enzyme.

Experiments were conducted using the samples shown in Table 4 below, and the degree of interleukin-6 activity was measured using the equation (3). The control group was ultraviolet B (UVB), which causes inflammation or blistering of the skin.
