Description

A moisturizing and nourishing cream with the same efficacy as far-infrared rays {NOURISHING CREAM COMPOSITION FOR KEEPING MOISTURE OF SKIN WITH CAPABILITY OF EMITTING FAR INFRARED RAY}

The present invention relates to a nutritional cream composition that provides a moisturizing effect to the skin and has a far-infrared emitting effect. It relates to a nutritional cream composition for moisturizing the skin that is excellent and has an excellent moisturizing effect.

Human skin needs an adequate amount of moisture to appear soft, supple and healthy on the outside. For this, the amount of moisture evaporation must be kept low even in a dry environment.

When the skin is dry, the upper layer of the epidermis is rough and dry, and its flexibility is reduced. When the dry condition of the skin worsens, the dead skin cells may be excessively detached or cracked, and in severe cases, it is classified as a skin disease. In addition, it has been reported that in dry skin, the bonding force between keratinocytes is weakened, the lipid component is changed, and the water retention capacity of the keratin is reduced.

Dry skin is not simply caused by a decrease in the moisture content of the skin. However, it has been reported that continuous application of LQN moisturizer to the skin improves the degree of dryness of the skin.

In addition, since an appropriate level of skin moisture content is an essential element for maintaining a normal skin condition, research on skin moisturizers for maintaining the moisture content of the skin is continuously being conducted. Conventionally developed skin moisturizers can temporarily maintain moisture content by simply moisturizing the skin. However, the ability of these moisturizers to penetrate the epidermis and penetrate deep into the skin or to fix moisture in the stratum corneum, which is easy to dry and acts as a barrier against moisture, is very insufficient, so it continuously maintains an appropriate level of skin moisture content. It has a problem that it is difficult to do.

For example, Korean Patent Publication No. 10-0659138 (published on December 19, 2006) discloses a moisturizing cosmetic composition comprising gallocatechin gallate as an active ingredient.

This moisturizing cosmetic composition activates the peroximal proliferator-activated receptor and promotes the expression of the skin moisturizing factor, thereby exhibiting a skin moisturizing effect. However, the cosmetic composition for moisturizing has a problem in that it is difficult to continuously maintain an appropriate level of skin moisture content because the function of penetrating deeply into the skin through the epidermis and fixing moisture in the stratum corneum is very insufficient. .

In addition, Korean Patent Publication No. 2006-0067296 (published on June 20, 2006) discloses a cosmetic composition for moisturizing the skin containing xylitol and beta-glucan at the same time.

This skin moisturizing cosmetic composition contains xylitol and beta-glucan in combination, thereby exhibiting a moisturizing effect on the skin. However, the cosmetic composition for skin moisturizing has a problem in that it is difficult to continuously maintain an appropriate level of skin moisture content because the function of penetrating deep into the skin through the epidermis and fixing moisture in the stratum corneum is very insufficient. .

Accordingly, it is an object of the present invention to provide a nutritional cream composition for moisturizing the skin that is made of natural materials and has no side effects on the human body, and has excellent skin penetration and moisture fixing function in the stratum corneum.

In order to achieve the above object of the present invention, in one embodiment of the present invention, there is provided a skin moisturizing cream composition comprising a liquid extract of pine needles, a liquid onion extract, a liquid green tea extract, a liquid extract of grapes, and additives.

According to the present invention, the nourishing cream composition for moisturizing the skin is made of natural materials, so there is no side effect on the human body, and it has an excellent moisturizing effect due to its excellent penetrating power to the skin and moisture fixing function in the stratum corneum.

In addition, the skin moisturizing cream composition prepared according to the present invention can greatly reduce the manufacturing cost because the manufacturing process is simple.

An embodiment of the skin moisturizing cream composition of the present invention will be described in detail.

The moisturizing cream composition for skin moisturizing of the present invention comprises 40 to 50 parts by weight of a liquid extract of pine needles, 7 to 12 parts by weight of a green tea liquid extract, and 8.7 to 11.3 parts by weight of an additive, wherein the additive is a moisturizer based on 100 parts by weight of alkaline ionized water. 4 parts by weight, 2.2 to 2.8 parts by weight of squalane, 2.1 to 2.7 parts by weight of a viscosity modifier, and 1.4 to 1.8 parts by weight of an emulsifier.

In the present invention, various components used to prepare the nutritional cream composition are dissolved, and alkaline ionized water is used as a solvent to improve penetration into the skin and provide a moisturizing effect to the prepared nutritional cream composition.

Electrolysis of water separates negatively charged alkaline ionized water and cationically charged acidic ionized water. In the present invention, it improves penetration into the skin and provides a moisturizing effect, while effectively fixing the nutrient cream composition to the stratum corneum. For this purpose, the alkaline ionized water is used as a solvent. In addition, alkaline ionized water not only combines with harmful oxygen (active oxygen) generated inside the human body and discharges it to the outside of the human body, but also has energy to attract various acidic wastes, thereby enhancing natural immunity.

Water exists not in a state in which water molecules are uniformly distributed, but in a state in which a large number of water molecules are agglomerated in a cluster state. have.

The size of the clusters of water molecules as described above may be measured by a nuclear magnetic resonance measuring instrument (NMR). As a result of measuring the size of the clusters of water molecules in common tap water using a nuclear magnetic resonance measuring device, the size of the clusters of water molecules in tap water is 120 Hz, whereas the size of cells in the human body is 60 Hz. It is extremely difficult for the water molecules of the skin to pass through the epidermis of the skin to penetrate the human body or to be fixed in the stratum corneum. As described above, if it is extremely difficult for water molecules with large clusters to pass through the epidermis of the skin, it is extremely difficult for various dissolved components to pass through the epidermis of the skin, and the function of properly moisturizing the skin of the human body is insufficient. Therefore, tap water or purified water simply purified from tap water cannot be used to constitute the nutritional cream composition of the present invention.

However, as water is highly electrolyzed and the negative ions are highly charged, the size of the clusters of water molecules tends to decrease. Therefore, in the present invention, by electrolyzing water and separating it from acidic ionized water, alkaline ionized water having a size of 54 Hz water molecule clusters smaller than human cells due to a large amount of negative ions is used as a solvent to construct a nourishing cream composition. do. As described above, when alkaline ionized water having a cluster size of 54 Hz smaller than the cells of the human body is used as a solvent by highly electrolyzing water to charge a large amount of anions as described above, the penetration ability of the prepared nutrient cream composition through the skin epidermis is improved. The effect of fixing moisture in the stratum corneum and moisturizing the skin of the human body is also greatly improved.

Using alkaline ionized water as described above as a solvent, a mixture which is an intermediate material for preparing a nourishing cream composition is constituted. However, since a significant portion of the alkaline ionized water evaporates during the manufacturing process of the moisturizing cream composition according to the present invention, only the component ratio between the remaining components except for the alkaline ionized water is specified in the claims.

The mixture according to an embodiment of the present invention contains 40 to 50 parts by weight of the liquid extract of pine needles based on 100 parts by weight of alkaline ionized water as a solvent (based on the initial input amount).

The pine needles, the raw material of the pine needle extract, are rich in terpene-type phytoncides and generate negative ions on their own, and are rich in vitamins and minerals beneficial to the human body. In addition, pine needles provide a pine scent to the atopic eczema reliever composition using natural materials to improve user satisfaction. In the present invention, the mixture is composed of a liquid extract of pine needles, which is a liquid component recovered by crushing and filtering pine needles.

If the content of the liquid extract of pine needles contained in the mixture based on 100 parts by weight of alkaline ionized water is less than 40 parts by weight, the amount of anions generated and the content of vitamins and minerals of the nutritional cream composition prepared by the mixture is reduced, and the mixture contains 100 parts by weight of alkaline ionized water. When the content of the liquid extract of pine needles contained based on parts by weight exceeds 50 parts by weight, the pine scent of the nutritional cream composition prepared by the mixture becomes too strong.

In addition, the mixture according to one embodiment of the present invention contains 7 to 12 parts by weight of green tea liquid extract based on 100 parts by weight of alkaline ionized water as a solvent.

Green tea leaf, the raw material of green tea liquid extract, contains a large amount of catechin, and has excellent anti-aging, anti-cancer and sterilization functions. .

In the present invention, the mixture is composed of a green tea liquid extract, which is a liquid component recovered by crushing and filtering green tea leaves.

If the content of the green tea liquid extract contained in the mixture based on 100 parts by weight of alkaline ionized water is less than 7 parts by weight, the sterilization effect and the content of various nutrients of the nutritional cream composition prepared by the mixture are reduced, and the mixture contains 100 parts by weight of alkaline ionized water. When the content of the green tea liquid extract contained on a part basis exceeds 12 parts by weight, the green tea flavor of the nutritional cream composition prepared by the mixture becomes too strong.

In addition, the mixture according to an embodiment of the present invention contains 3 to 4 parts by weight of a moisturizing agent based on 100 parts by weight of alkaline ionized water as a solvent.

The moisturizing agent included in the mixture has a very excellent moisturizing action to fix moisture and it is preferable to use glycerine, which is harmless to the human body.

Glycerin is a liquid that is produced together with fatty acids or synthesized from petroleum when oil is hydrolyzed. It is colorless and transparent, has a high viscosity, and has excellent moisturizing properties that fix moisture and is harmless to the human body. Due to these characteristics, glycerin is widely used as a raw material for pharmaceuticals, explosives, cosmetics, etc., or as a lubricant for machinery.

If the content of the moisturizing agent contained in the mixture based on 100 parts by weight of alkaline ionized water is less than 3 parts by weight, the boss action of the nourishing cream composition prepared by the mixture is reduced, and the moisturizing agent contained in the mixture based on 100 parts by weight of alkaline ionized water is If the content exceeds 4 parts by weight, the viscosity of the mixture increases, making it difficult to separate solid/liquid.

In addition, the mixture according to an embodiment of the present invention contains 2.2 to 2.8 parts by weight of squalane based on 100 parts by weight of alkaline ionized water as a solvent.

Squalane contained in the mixture is a polyunsaturated hydrocarbon made in living organisms, and generally refers to oil extracted and refined from deep-sea shark liver oil. Squalane is produced within the human body and is distributed in various tissues such as the liver, gallbladder, and skin. It is known to be a substance that can reduce allergic reactions. Squalane supplies sufficient oxygen to the human body to promote metabolism and prevent skin aging. Accordingly, cosmetics such as lotions, paintings, and essences often contain a certain amount of squalane.

If the content of squalane contained in the mixture based on 100 parts by weight of alkaline ionized water is less than 2.2 parts by weight, the skin affinity and oxygen supply function of the nutritional cream composition prepared by the mixture is reduced, and the mixture contains 100 parts by weight of alkaline ionized water When the content of squalane to be used exceeds 2.8 parts by weight, the manufacturing cost of the nutrient cream composition prepared by the mixture increases.

In addition, the mixture according to an embodiment of the present invention contains 2.1 to 2.7 parts by weight of a viscosity modifier based on 100 parts by weight of alkaline ionized water as a solvent.

The viscosity modifier included in the mixture is xanthan gum, which has excellent viscosity control function, cetearyl alcohol, which can soften and nourish the skin, and a mixture of xanthan gum and cetearyl alcohol. It is preferable to do

Xanthan gum used as a viscosity modifier in the present invention is a high-molecular polysaccharide gum material obtained by pure culture fermentation of carbohydrates purified, dried, and pulverized in isopropyl alcohol, and is soluble in water and not ethanol. This xanthan gum has good viscosity compared to other thickeners, and the viscosity gradually increases according to the concentration, there is no decrease in viscosity due to pH, and the safety is excellent even within the range of pH 2-13. Due to these properties, xanthan gum is used as a stabilizer, thickener, binder, emulsifier, binder, foaming agent, etc. to increase the adhesion and viscosity of food, enhance emulsion stability, and improve the physical properties and feel of food.

Cetearyl alcohol used as a viscosity modifier in the present invention is an odorless light oil obtained by alkyne pressing of sweet almond fruit, and has the properties of softening the skin and supplying nutrients.

If the content of the viscosity modifier contained in the mixture is less than 2.1 parts by weight based on 100 parts by weight of alkaline ionized water, it is difficult to control the viscosity of the mixture, and the skin softening function and nutrient supply function of the nutrient cream composition prepared by the mixture are reduced. , when the content of the viscosity modifier included in the mixture, based on 100 parts by weight of alkaline ionized water, exceeds 2.7 parts by weight, the viscosity of the mixture increases more than necessary.

In addition, the mixture for preparing the nourishing cream composition includes 1.4 to 1.8 parts by weight of an emulsifier based on 100 parts by weight of alkaline ionized water as a solvent.

The emulsifier included in the mixture is preferably glyceryl stearate, which provides a skin lubricating function while having an excellent emulsifying function.

Glyceryl stearate is an emulsifier, solvent, and moisturizer that forms a neutral and stable emulsion. It has excellent emulsion control ability in pharmaceuticals and cosmetics, and has excellent skin lubrication function.

If the content of the emulsifier contained in the mixture based on 100 parts by weight of alkaline ionized water is less than 1.4 parts by weight, the emulsification control function of the mixture is reduced, and the content of the emulsifier contained in the mixture based on 100 parts by weight of alkaline ionized water exceeds 1.8 parts by weight The emulsification control function is provided to the mixture.

The mixture composed as described above is fermented at 27 to 30° C. for 5 to 7 days. In the fermentation process of this mixture, a solid component of the mixture is precipitated, and the mixture is solid/liquid separated into a precipitate and a supernatant.

If the temperature at which the mixture is fermented is less than 27°C, the mixture is not fermented properly, and if the temperature at which the mixture is fermented exceeds 30°C, the mixture may be denatured.

In addition, if the period for fermenting the mixture is less than 5 days, the mixture is not fully fermented, and if the period for fermenting the mixture exceeds 7 days, the mixture is no longer fermented.

The fermentation process of such a mixture is preferably carried out in a reactor made of ceramic material so that the mixture during fermentation does not deteriorate.

In the fermentation process of the mixture as described above, the solid/liquid separated mixture into the precipitate and the supernatant is filtered, and the supernatant is recovered.

The supernatant is gelled at 63 to 67° C. for 60 to 65 minutes to form a gel.

If the temperature at which the supernatant is gelled is less than 63°C, the supernatant is not properly gelled, and when the temperature at which the supernatant is gelled exceeds 67°C, there is a possibility that the supernatant may be denatured.

In addition, if the time to gel the supernatant is less than 60 minutes, the supernatant is not sufficiently gelled, and if the time to gel the supernatant exceeds 65 minutes, the supernatant is no longer gelled.
