Method for producing a cosmetic composition containing plant extracts having a moisturizing effect and a cosmetic composition produced thereby {Cosmetic composition containing plant extracts having skin moisturizing Effect, a preparation method thereof}

The present invention relates to a method for producing a cosmetic composition containing a plant extract with a moisturizing effect and to a cosmetic composition produced thereby. More specifically, the present invention relates to a method for producing a cosmetic composition containing a plant extract having a moisturizing effect, and more specifically, to a method for producing a cosmetic composition containing a plant extract having a moisturizing effect, and more specifically, to providing an excellent feeling of use by containing cucumber grass extract and elm root extract, causing discomfort due to stickiness. It relates to a method for producing a cosmetic composition containing a plant extract that has a moisturizing effect that eliminates odor and suppresses off-odor even when stored for a long period of time, and to a cosmetic composition produced thereby.

The skin carries approximately 65-70% of the moisture contained in the human body, that is, various physiologically active substances needed by the human body, and plays an important role in controlling the evaporation of this moisture out of the body, helping the skin maintain a soft and moist state. Do it.

The epidermis of the skin is divided from the outside into the stratum corneum, stratum granulosum, stratum spinosum, and basal layer. The cells of the stratum corneum act like bricks, and the intercellular lipids between keratinocytes act like mortar, forming the skin barrier. (J. Invest. Dermatol. 80(Suppl.), 44-49. 1983). The stratum corneum of the epidermis contains approximately 10 to 20% of moisture and exists in the outermost layer of the human body, thereby suppressing moisture evaporation to the outside of the body and blocking excessive penetration of substances from the outside. The stratum corneum is made up of inucleated cells, with flat, grayish-white pieces arranged in a lamellar structure (brick structure). Intercellular lipids and natural moisturizing factors (NMF) act as cement to fill the space between the bricks, making it easier for keratinocytes to absorb. Hold it so it doesn't fall. The cells that make up this stratum corneum contain a high concentration of natural moisturizing factor (NMF), a water-soluble component that not only helps maintain appropriate moisture but also helps the skin show flexibility.

However, due to various causes such as artificial temperature control of heating and cooling due to environmental changes or changes in lifestyle patterns, frequent face washing due to makeup habits, skin stress due to various stresses and environmental pollution, and natural skin aging due to age. The need for skin moisturizers is increasing because the moisture in the stratum corneum decreases, causing the skin to dry out, the surface to become rough, and the skin to lose its luster and appear dull.

Conventionally, the most widely used method for this purpose is to increase moisture retention in the stratum corneum to moisturize the skin by using humectants, which have the property of absorbing moisture, or occlusive moisturizers, which prevent moisture evaporation. It was done. Humectants are mostly polyols and contain substances such as glycerin, propylene glycol, 1,3-butylene glycol, and polyethylene glycol. However, they have the disadvantage of being sticky when applied to the skin due to the inherent viscosity and physical properties of polyol.

The cosmetic composition for skin moisturizing containing cucumber plant extract and its manufacturing method of the previously registered patent No. 1020536 moisturizes the skin due to the effects of cucumber plant extract, such as increasing epidermal moisture content, inhibiting epidermal water evaporation, anti-inflammatory, antioxidant, collagen biosynthesis, and fibroblast proliferation.

The roots branched off from the thick rhizome become thick in the shape of a cylinder with sharp ends, and the stem grows straight to about 1m, with branches branching at the top. The leaves are alternate, pinnate compound leaves, the root leaves have 7 to 11 leaflets, and have petioles and small petioles. The small leaves are long oval shaped and have serrated edges, and the stem leaves become smaller and have no stems. Types include cucumber plant, slender cucumber plant, long cucumber plant, large cucumber plant, mountain cucumber plant, fine cucumber plant, tufted cucumber plant, plume cucumber plant, beaded cucumber plant, and cloud cucumber plant.

Cucumber grass is effective in hemostasis, detoxification, burns, boils, athlete's foot, eczema, diarrhea, dysentery, stomach bleeding, intestinal bleeding, excessive gastric acid, mouth sores, menstrual pain, astringency, colitis, hematemesis, excessive menstruation, excessive childbirth bleeding, and bleeding from trauma. In addition, in oriental medicine, the root is called Jiyu (地楡) and is used for astringency, fever, diarrhea, dysentery, hemostasis, menorrhagia, hemoptysis, skin diseases, wounds, burns and lacerations, etc. It contains 17% of tannin and saponin. .

The step of preparing a fermented product (S20) is a step of inoculating lactic acid bacteria into a mixture of cucumber grass extract, molasses, and purified water and fermenting it.

Lactic acid bacteria break down carbohydrates and use them to produce lactic acid, and are facultative or partial anaerobic bacteria. Lactic acid bacteria are divided into five genera: Streptococcus, Lactobacillus, Leuconostoc, Bifidobacteria, and Pediococcus.

It is preferable that it is Lactobacillus paracasei. Lactobacillus paracasei is a Gram-positive, non-spore-forming bacterium that is non-motile and is a lactic acid bacterium that can be easily isolated from kimchi or yogurt.
