Cosmetic composition containing Opuntia coccinellifera, Betula Alba Juice, Extra virgin olive oil and polyol for moisturizing the skin, including white lotus extract, birch sap, extra virgin olive oil and polyol

Figure 1 shows the change value of the transdermal moisture loss amount in the human body at the time of 1 week, 2 weeks, 4 weeks after the application of the cosmetic composition of the present invention.

Figure 2 shows the result of measuring the moisture level of the skin with a coronometer for 6 hours after the application of Example 1 and Example 2 to determine the moisturizing sustainability in one application with the case of the untreated group.

The present invention relates to a skin moisturizing cosmetic composition containing a moisturizing complex, and more particularly, containing white zinnia extract, birch sap, extra virgin olive oil and polyol. It relates to a skin moisturizing cosmetic composition showing an excellent skin moisturizing effect.

The skin is divided into three layers of epidermis, dermis and subcutaneous fat tissue in order from the outside, and protects the human body from physical and chemical stimuli from the external environment. In particular, the skin carries about 65-70% of the water that the body has, that is, the various biologically active substances necessary for the body, and it is important to control the evaporation of this moisture outside the body, which helps keep the skin soft and moist. Play a role. In addition, the epidermis is separated from the outside in the order of the stratum corneum, granule layer, polar layer, basal layer, the cells of the stratum corneum acts like a brick, and the intercellular lipids between the stratum corneum acts as a mortar to form a skin barrier. (J. Invest. Dermatol. 80 (Suppl.), 44-49. 1983). The stratum corneum of the epidermis contains about 10 to 20% of water and is present at the outermost part of the human body, thereby suppressing evaporation of moisture into the body and blocking excess penetration of substances from the outside. These stratum corneum surfaces are wrapped with a thin natural protective film made of sebum from the sebaceous glands and perspiration from the sweat glands, which can prevent water evaporation. To explain further, you can think of a sponge (stratum corneum) that fills up with water wrapped in a plastic wrap (a natural protective film) that does not pass water. The cells constituting the stratum corneum have high concentrations of natural moisturizing factors (NMF), which are water-soluble ingredients, which help the skin to show flexibility and maintain proper moisture. The substance is not only water soluble, but also effectively binds to moisture and inhibits the drying of moisture from the skin (J. Invest. Dermatol. 54, 24-31, 1970). However, artificial temperature control of cooling / heating due to changes in environment or life patterns, skin stress caused by various stresses and environmental pollution in social life, and frequent skin washing due to makeup habits and age increase Due to various causes such as the decrease in moisture of the stratum corneum, the skin is dried, the surface is rough, and the skin loses luster, so that the appearance of dull appearance occurs, the need for a skin moisturizer is increasing.

In the past, a method of increasing the moisture retention in the stratum corneum has been widely used by using a humectant having a property of absorbing moisture as a humectant and an occlusive moisturizer preventing evaporation of water. Most of the humectants are polyols and include glycerin, propylene glycol, 1,3-butylene glycol, and polyethylene glycol. However, they are disadvantageous in that they are sticky or worn out due to the inherent viscosity and physical properties of the polyol upon application to the skin. As a closed humectant, lipid components such as ceramides and essential fatty acids and lipid complexes have been used (J. Invest. Dermatol. (5), 731-740, 1994), but the structure of emulsified interfacial membranes is disturbed in the emulsified formulations, But it has drawbacks and is unsuitable for producing transparent gel-like products. In addition, formulations containing lamellar liquid crystals, which have been studied until recently, are known to have excellent moisture moisturizing properties with advantages similar to the skin keratin structure, but may be manufactured only in specific compositions of raw materials, and thus there are problems in general use.

Accordingly, the present inventors have studied cosmetics composition to find a substance containing a large amount of moisture in the stratum corneum and reduce the evaporation of water, according to the inventors, the white lotus extract in natural products has a high moisture retention capacity, containing a large amount of moisture and water evaporation Decreases skin transparency, skin roughness, skin glossiness, and fine wrinkles due to the lack of moisture in the stratum corneum due to changes in the environment such as temperature changes, humidity decreases, and wind. It has been found to make it possible to prevent the cause of the back. In addition, the present invention was completed by discovering that the effect is further enhanced by applying polyol to birch sap, which is rich in various minerals, and to extra virgin olive oil having excellent moisturizing effect.

Accordingly, an object of the present invention is to provide a large amount of water in the stratum corneum and to reduce the evaporation of water, thereby preventing and improving all the symptoms of the skin due to lack of moisture, excellent skin moisturizing power, safe and effective moisturizing It is to provide a cosmetic composition for.

In order to achieve the above object, the cosmetic composition according to the present invention is characterized in that it contains a moisturizing complex (moisturizing complex) containing white lotus extract, birch sap and extra virgin olive oil as an active ingredient.

In addition, the cosmetic composition is characterized in that it further comprises a polyol as an active ingredient in the moisturizing complex.

Hereinafter, the present invention will be described in more detail.

In detail, the moisturizing complex consists of extracts of white lotus, which are excellent in supporting and retaining moisture in nature, and birch sap, which is rich in various minerals, and extra virgin olive oil, which is used as a moisturizer. can do.

White lotus is a kind of cactus whose fruit is red and has a sour taste. It is rich in minerals such as calcium, magnesium, sodium and iron, and flavonoids with excellent anti-aging effects. The vitamin C content is as high as 5 times that of aloe, and the fiber content is 30%, compared to general fruits and fresh vegetables. It is much richer. The origin of the centennial plant, designated as Jeju Island Provincial Monument No. 35, is Mexico. It has long been driven by currents from the Gulf of Mexico, and has been inhabited and settled in the sand beaches and rocky creeks of Jeju Island. White lotus is a flower of a cactus that lives for 100 years. As its name suggests, its efficacy is excellent. White lotus is a plant that can withstand long drying periods because it has a round body with over 99% moisture. This extraordinary hydrating capacity moisturizes the skin while helping to shine and moisturize the skin.

Birch is a deciduous tree belonging to the birch family and grows in high mountains north of Gangwon-do, but it is also distributed in Hokkaido and China in Japan. Its height is 20m and the bark is white and peeled horizontally. Birch is also used in various places. Bark is used instead of paper because it doesn't decay after 10 thousand years and 10-12 thin skins are peeled off. Instead of bark, roots, sap, and mushrooms that stick to trees are used as medicinal herbs. Among them, birch sap is a colorless and transparent sap that flows through a small hole in birch trees in early spring. Birch sap contains amino acids, sugars and minerals, and is similar to NMF and is a natural moisturizer that helps to maintain the skin's moisture balance.

Olive oil contains azelic acid to nourish dry skin, keratin, hair, etc. It is good for dry skin or atopic skin, promotes blood circulation during skin massage, and is due to unsaturated fatty acids in olive oil. Skin barrier function is enhanced, increasing the skin's protective action against external harmful environment. In particular, extra virgin olive oil is a high quality olive oil with an acidity of less than 1%.

Polyol is a humectant having excellent water absorption effect and is commonly used as a moisturizer in cosmetic formulations, and includes glycerin, dipropylene glycol, propylene glycol, 1,3-butylene glycol, polyethylene glycol, and the like.

Moisturizing complex according to the present invention is a combination based on scientific basic data on the skin when using a mixture of white lotus extract, birch sap, extra virgin olive oil, polyol, thereby realizing its long-term efficacy in terms of skin moisturizing Can be.

Cosmetic compositions using the same can be used in cosmetics for moisturizing the skin, there is no particular limitation in the formulation, emulsion, cream, lotion, essence, pack, gel, powder, lipstick, makeup base, foundation, lotion, ointment, Gels, patches, cosmetics, cleansing foams, cleansing creams, cleansing waters, sprays, shampoos, rinses, treatments, body cleansers, soaps or other cleansing agents. have.

Experimental Example 1 Moisturizing Effect Experiment of Moisturizing Complex

In order to measure the effect of improving the skin moisturizing power of the cosmetic table composition prepared in Table 1, the cosmetic composition of Examples 1, 2 and Comparative Examples 1 to 5 to 50 adult men, women who are dry or thought to be dry skin Was applied twice a day for 4 weeks inside Habak. Moisturizing power was compared by measuring Trans Epidermal Water Loss (TEWL) at constant temperature and humidity conditions (24 ° C, 40% RH) at the time of application, 1 week, 2 weeks, and 4 weeks after application. The results are shown in FIG. 1.

<How to measure Trans Epidermal Water Loss (TEWL)>

The amount of water evaporating from the skin was calculated according to the area and time, and the amount of water evaporated was read and quantified by the temperature and humidity electronic sensor to measure the moisture of the skin.

1. Environmental conditions: Temperature and humidity were kept constant, and the flow of air was cut off as much as possible, leaving only the minimum number of personnel except the measuring person and the subject.

2. Transepidermal Moisture Loss (TEWL) probe was placed on the subject's measurement site.

3. Do not apply excessive force to the measuring part, and put it lightly so that no marks remain on the skin and make an angle of 90 degrees with the ground.

4. Over time, the value of the skin's TEWL value was measured (usually 1-3 minutes).

5. Keep the probe handle as far as possible to prevent the body temperature from being transferred.

6. The amount of water evaporated per hour per area (g / m 2 / h) was calculated.

1 shows that the formulations containing the moisturizing complexes I and II mixed with white lotus extract, birch sap, and the extra virgin olive oil showed a tendency to decrease the TEWL change value (water evaporation amount) over time. have. Therefore, it can be seen that Examples 1 and 2 have a larger moisturizing effect than Comparative Examples 1 to 5. In particular, it can be seen that the moisturizing complex I containing the polyol further reduced the TEWL change compared to the moisturizing complex II.

 Experimental Example 2 Measurement of Moisturizing Duration in One Application

In order to determine the moisturizing sustainability in one application, after applying Examples 1 and 2, the skin moisture content was measured by a Koniometer for 6 hours, and the results are shown in FIG. 2 together with the untreated group.

<How to measure a corneometer>

The moisture level was measured by measuring the amount of moisture in the skin's epidermis using a sensor and quantifying it to calculate the amount of moisture.

1. The probe of the Koniometer was placed on the skin area to be measured.

2. When the probe is pressed on the skin, the electrical conductivity of the skin is quantified through the sensor and displayed on the screen.

3. The measurement was repeated with different measurement sites.

4. After the measurement, wipe the sensor with a tissue such as Kimwipe and use the instrument.

2 shows a one-time formulation containing a moisturizing complex I mixed with white vinegar extract, birch sap, extra virgin olive oil and polyol, or a moisturizing complex II mixed with white lotus extract, birch sap and extra virgin olive oil. In this case, it was confirmed that the moisturizing effect is excellent.

Experimental Example 3 Evaluation of Subjective Efficacy on Skin Dryness Improvement Effect

At the end of the test of Experimental Example 1, the test subjects were asked to fill out a questionnaire, and subjective efficacy evaluation of the improvement of skin dryness was performed. The survey results are shown in Table 2.

Applicator Respondents Very good Good usually Inadequate Example 1 23 22 5 0 Example 2 19 19 10 2 Comparative Example 1 5 10 26 9 Comparative Example 2 5 11 24 10 Comparative Example 3 8 18 19 5 Comparative Example 4 6 13 25 6 Comparative Example 5 One 5 26 18

Looking at the results of Table 2 above, it can be seen that the results of the survey were found to feel that the moisturizing effect was relatively higher than the moisturizing areas of Examples 1 and 2 than the areas of Comparative Examples 1-5.

As described above, the cosmetic composition provided by the present invention contains a moisturizing complex of white vinegar extract, birch sap, extra virgin olive oil, and polyol, and the moisturizing effect is to use each component separately. Since it is much superior to the present invention can provide a cosmetic composition excellent in the skin moisturizing effect.
