Description

Cosmetic composition for skin moisturizing {Cosmetic Composition}

The present invention relates to a functional cosmetic composition prepared by using an extract having a skin moisturizing effect in plants, and more particularly, to a cosmetic composition having excellent skin moisturizing effect by containing white lotus and edelweiss extract components.

In addition, it contains the complex extract ingredients of licorice and sanjoin extract which have skin antibacterial effect, etc. in addition to white lotus and edelweiss extracts, while providing excellent moisturizing effect, antimicrobial effect against skin regrowth bacteria, improvement of skin recovery speed and alleviation of skin irritation It relates to a cosmetic composition excellent even in the effect.

The skin is divided into three layers of epidermis, dermis and subcutaneous fat tissue from the outside, and protects the human body from physical and chemical stimuli from the external environment. In particular, skin carries about 65 ~ 70% of the human body's moisture, that is, various physiologically active substances necessary for the human body, and plays an important role in regulating the evaporation of water to the outside of the body which helps the skin to maintain a smooth and moist condition . In addition, the epidermis is divided into stratum corneum, granular layer, superficial layer, and basal layer from the outside. Cells of the stratum corneum act like bricks, and intercellular lipids between keratinocytes function as mortar to constitute skin barrier. The stratum corneum of the epidermis contains about 10 to 20% of water and exists in the outermost part of the human body, thereby inhibiting moisture evaporation to the outside of the body, while blocking excessive material penetration 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. Cells constituting these stratum corneum have a high concentration of natural moisturizing factor, which is a water-soluble component, and acts to provide flexibility to the skin, as well as to prevent moisture from drying on the skin by binding with proper moisture.

However, artificial temperature control of cooling / heating according to changes in environment or life patterns, skin stress caused by various stresses and environmental pollution from social life, frequent face wash due to makeup habits and natural skin aging due to age increase Due to various causes of the moisture in the stratum corneum is reduced, the skin is dried, the surface is rough, and the skin loses shine, dull appearance occurs, the need for a skin moisturizer is increasing.

Conventionally, a humectant which absorbs moisture as a moisturizer or a closed moisturizer that prevents evaporation of water is widely used, and thus a method of increasing moisture retention in the stratum corneum is widely used, but most of the humectants are polyols and glycerin When applied to the skin with materials such as propylene glycol, 1,3-butylene glycol, polyethylene glycol, etc., there was a disadvantage that the stickiness was severe or damp due to the inherent viscosity and physical properties of the polyol.

In addition, in the past, cosmetics manufacturers have been making efforts to alleviate irritation and mobilized various methods such as removing skin irritants to alleviate skin irritation. Has often acted as a source of stimulus, limiting this effort.

 According to the present invention, the cosmetic composition contains a large amount of water in the stratum corneum and researches to find a substance that reduces water evaporation. As a result, white lotus extract has excellent water retention and thus contains a large amount of water and reduces water evaporation. It has been found that it prevents the causes of reduced skin transparency, skin roughness, skin glossiness, and fine wrinkles. In addition, by extracting and using the edelweiss, licorice extract and Sanjoin extract, it was found that the effect is not only exerted on the skin's moisturizing power, but also on the cell regeneration, inflammation removal, and skin stimulation.

Accordingly, an object of the present invention is to obtain a cosmetic composition having excellent skin moisturizing effect, antifungal effect on skin flora, damaged skin improvement effect, skin irritation relieving effect by using complex extract of white lotus, edelweiss and licorice, sanjoin .

In order to achieve the above object, the cosmetic composition according to the present invention is characterized by selectively containing any one or more of white lotus extract, Edelweiss extract or white lotus extract, Edelweiss extract, licorice extract and sanjoin extract.

In addition, in the cosmetic composition of the present invention, the moisturizing complex including the white lotus extract and the edelweiss extract is characterized in that it contains 10 to 20% by weight based on the total weight of the composition.

 In addition, in the cosmetic composition of the present invention, the moisturizing complex containing the white lotus extract, edelweiss extract, licorice extract and sanjoin extract is characterized in that it contains 10.5 to 30% by weight based on the total weight of the composition.

As described above, the cosmetic composition according to the present invention contains white lotus extract, Edelweiss extract to obtain an excellent skin moisturizing effect.

In addition, it is possible to obtain an excellent skin moisturizing effect, antibacterial effect on skin flora, damaged skin improvement effect, skin irritation relief effect by additionally containing licorice extract and sanjoin extract in white lotus extract, edelweiss extract.

Hereinafter, the present invention will be described in detail.

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 five times higher than aloe, and the fiber content is 30%. It is much higher than that. The origin of the white lotus is Mexico, which has long been driven by currents from the Gulf of Mexico, and has been inhabited and settled in the sand beaches and rock formations on Jeju Island. White lotus is a flower of a cactus, and it is said to live 100 years. White lotus is a plant that can withstand long drying periods because it has a round body with over 99% moisture. This extraordinary moisture retention helps moisturize and moisturize your skin.

Edelweiss is an alpine plant that is a perennial plant of the dicotyledon plant Lantern Asteraceae, 10 ~ 20㎝ high, and covered with white cotton. The leaves are relatively high in the roots, slightly on the stems, and linear. At the end of the stem, the squirrel gathers and spreads out in all directions, with a slight heading in the center. Edelweiss grows in dry places and is distributed in Europe, Siberia, the Himalayas, China, Korea, Japan, and Sakhalin, but not in the polar regions. Cosmetically, there are many flavonoids such as luteolin and luteolin-7-glucoside, which have a soothing effect and antioxidant activity, and absorb ultraviolet rays to prevent ultraviolet rays from reaching the skin.

Sanjoin means the seed of mountain jujube, and mountain jujube is different from the kind and efficacy of jujube grown and produced generally in Korea.

Mountain jujube is a deciduous shrub, grows about 2-4m in height, young branches are green, and branches have needle-like and semi-curved spines. The leaves are regenerated, egg-shaped, and have a balance and luster. Similar to the leaves of jujube tree, but a little smaller. It is a small yellow-green flower in May-June, and fruit matures in September-October. Unlike jujube, the seeds of this plant are long oval, light reddish brown, almost without flesh, fruit with thin skin, whole with seeds, and fruit is 0.8-1cm long and shorter in diameter. The leaves of this plant are called Sanjo Leaf and the root bark is called Medicinal Sanjokeunpi.

The components of the acid join include the cyclopeptide alkaloids sanjoinine A, B, D, F and G, mauritine A, mucronin D, jubanine A, B. Examples of peptide alkaloids include sanjoinine, and apophine alkaloids such as zizyphusine.

On the other hand, the present inventors confirmed that the Sanjoin extract reduces the secretion of cortisol, a type of stress hormone, increases the amount of endorphins, alleviates pain and improves mood.

The acid extract used in the present invention may be obtained through various methods known in the art, and preferably water, anhydrous or hydrous lower alcohol having 1 to 4 carbon atoms, acetone, ethyl acetate, chloroform or 1,3- Butylene glycol was obtained from the above acidzoin using an extraction solvent.

The acid join which becomes the material of extraction can be used by drying it, or it can be used as it is, Preferably it is used by drying. As a drying method, natural drying or a hot air drying method can be used.

Sanjoin extract of the present invention is to mitigate cell stimulation caused by foreign substances and anti-inflammatory activity, and to relieve skin irritation by cosmetic raw materials.

Licorice is known to be effective in reinforcing skin cell activity and regeneration, antioxidant activity, free radical scavenging and inhibitory effect on inflammation mediators. Licorice has already been found to be excellent in stimulating relaxation, and the contents have been transmitted in the old literature, and the present inventors have already used licorice extensively for the skin irritation relief effect.

In the present invention, when the mixture of Sanjoin extract and licorice extract is used, it was confirmed that the cell stimulation relaxation and anti-inflammatory effects were significantly improved compared with the use of each component alone. According to a preferred embodiment of the present invention, the ratio of Sanjoin extract to licorice extract is preferably 1:10 or vice versa 10: 1, and a particularly preferred ratio is 1: 1.

According to a preferred embodiment of the present invention, the content of the extract is 0.0001 to 10.0% by weight based on the total weight of the cosmetic composition.

Cosmetic compositions using the same can be used in cosmetics for moisturizing the skin, the formulation is not particularly limited, latex, cream, lotion, essence, pack, gel, powder, lipstick, makeup base, foundation, lotion, ointment, It can be used in the formulation of cosmetic liquids, cleansing foams and sprays, and can take the form of solutions, emulsions, viscous mixtures and the like.

Hereinafter, the present invention will be described in more detail with reference to experimental examples.

[Manufacture of white lotus extract]

The white lotus extract was extracted by heating 30kg of white lotus, which was purchased from Bukjeju-gun, Jeju, Korea for 3 hours at 900 ° C of ultrapure water, and then filtered and concentrated to about 1/10 to obtain a concentrated solution of 100kg. Then, the concentrated solution was precipitated and dehydrated, and 1 kg of precipitate obtained by heating and again extracted at 5 ° C. for 5 hours at 90 ° C. was used for extract experiments obtained through centrifugation and filtration.

Experimental Example 1 Moisturizing Effect Experiment

In order to measure the effect of improving the moisturizing power of the cosmetic composition comprising a white lotus flower extract, 50 men and women with dry or dry skin were applied twice a day for 4 weeks in the inner Habakku. Moisturizing power was compared by measuring the epidermal moisture loss at constant temperature and humidity conditions at the time of 1 week, 2 weeks, and 4 weeks after the start of application and at the time of application. As a result, it was confirmed that the cosmetic composition including the white lotus flower extract tends to have a small change in the amount of water evaporation over time.

 Therefore, it can be seen that the cosmetic composition including the white lotus extract has a greater moisturizing effect than the cosmetic composition not containing the same.

Experimental Example 2 Measurement of Moisturizing Duration in One Application

In order to determine the moisturizing sustainability in one application, after applying the cosmetic composition including the white lotus flower composition, the skin moisture content was measured by a Koniometer for 6 hours.

In the measurement method using a conniometer, the amount of moisture present in the epidermis of the skin was measured using a sensor, and the moisture content was measured by calculating the amount of moisture by quantifying the amount of moisture.

As a result, it was confirmed that the moisturizing complex containing the extract of the white lotus was far superior to the moisturizing complex that did not contain the white lotus extract.

To obtain an edelweiss extract can use the leaves and flowers of the edelweiss. As the extraction solvent, alcohols such as methanol, isopropyl alcohol, propylene glycol, ethanol, purified water and the like can be used. At this time, the ratio of the dry raw material and the extraction solvent is preferably in the weight ratio of 1: 4 to 1: 9 in terms of extraction efficiency.

This extraction is carried out for 3 to 48 hours at 40 ~ 80 ℃ by adding a ratio of the extraction solvent to the raw material, it is filtered to remove the insoluble material. In addition, activated carbon can be used to remove color and odor.

Manufacture of Edelweiss Extract

Naturally dried edelweiss leaves and flowers were ground and 90 g of purified water was added to 10 g of the pulverized product, followed by extraction at 80 ° C. for 48 hours, and filtered through 250 mesh to obtain 80 g of extract.

Experimental Example 3 Human Patch Test

Human patch test was performed to determine the skin irritation of the extract. After mixing the Na phase (hyaluronic acid, glycerin, purified water) to the extract and slowly rotating the stirrer to 1000 ~ 2000rpm into a multi-phase (caster oil, 95% modified ethanol, flavoring / preservatives) to prepare a skin lotion. This was applied to the upper arm of 30 women with healthy skin for 24 hours. It was then removed and the skin irritation measured, and after 24 hours, 48 hours later the skin irritation was measured again. As a result, Adelweiss extract was found to have less skin irritation.

Experimental Example 4 Skin Moisturizing Effect

Twenty five healthy women at 22 ~ 24 ℃, 55% relative humidity and no air flow were divided into 5 groups and 5 groups. Then, the prepared skin lotion was applied to the entire face twice a day for 6 weeks in each group. The duration of the moisturizing effect was measured by measuring the amount of moisture in the cheek area before and after the test and 6 weeks after application using Skicon-200. As a result, it was confirmed that the improvement was much better than that containing the edelweiss extract.

[Preparation of Licorice Extract]

After crushing the licorice finely weighed to 1kg and precipitated in an aqueous solution mixed with ethyl alcohol and wool 7: 3 and left for 5 days. After standing, the mixture was filtered using 300 mesh and the filtrate was concentrated at 80 ° C. using a vacuum vacuum concentrator. The licorice powder thus obtained was dissolved and used in 50% 1,3-butylene glycol for easy application to the product again.

Sanjoin Extract Preparation

The acid joins are washed with purified water, dried and broken into small pieces, and then 70% lower alcohol of 1-10 times the dry weight is added thereto. After extraction for 5 days at 15 ~ 35 ℃ filtered with 300 mesh filter cloth, and filtered again with the filter paper Wharman No. 5, dried by rotary evaporation to obtain a dry weight 47g / kg. The dried acidic extract powder was used dissolved in 50% 1,3-butylene glycol.

Experimental Example 5 Lactonic Acid-Reducing Effect of Licorice Extract and Sanjoin Extract

Twenty females in their 20s and 30s were treated with a cream containing 5% lactic acid and 2% licorice extract or 2% sanjoin extract or 2% of the above extract mixture (Licorice extract: Sanjoin extract = 1: 1). It was allowed to use for 10 days. Each morning and evening were used, and then questionnaires were marked for skin irritation and intensity. Test results were evaluated once a day, and divided into subjective and objective stimuli.

Looking at Table 1, it can be seen that the licorice extract and Sanjoin extract when used in a 1: 1 mixture exhibits a superior skin irritation relief effect compared to using these extracts alone. In particular, the licorice extract contributed to the relaxation of the objective stimulus, and the extract contributed to the reduction of the subjective stimulation.

Through the above experimental examples, it was confirmed that the mixture of white zinnia extract and edelweiss extract having excellent skin moisturizing effect was excellent in moisturizing effect, and edelweiss extract, licorice extract and sanjoin extract greatly helped to alleviate skin irritation and mixed them. In this case, it can be seen that the synergistic effect becomes more thick.

Therefore, when the cosmetic composition is prepared by mixing white lotus and edelweiss extract cosmetic composition with excellent skin moisturizing effect can be completed.

In addition, when mixing the white lotus, edelweiss and licorice, Sanjoin extract to produce a cosmetic composition can be completed a cosmetic composition to maximize the skin moisturizing effect, antibacterial effect and skin irritation effect.

If the composite extract occupies too little specific gravity in the total weight of the composition, if the effect is not excessive and occupies too much specific gravity, the effect also affects stability and the cost is at least 10-30% by weight, which is most effective. Among them, the preferred range of licorice extract and sanjoin extract is 0.0001 to 10.0 wt%, and the specific gravity of white lotus and edelweiss extract is preferably mixed in a range of 10 to 20 wt%.

When mixing all white extracts, edelweiss, licorice and Sanjoin extract, the specific gravity of the extract is preferably mixed in the range of 10.5 ~ 30% by weight.
