Description

The preparation method of skin moisturizing composition containing pine needle extract {THE PREPARATION METHOD OF COMPOSITION FOR MOISTURIZING SKIN COMPRISING EXTRACTS OF PINE NEEDLE}

The present invention provides a method for producing a skin moisturizing composition having excellent skin moisturizing effect, excellent in far infrared rays and anion releasing effect, and more particularly, a method for preparing a skin moisturizing composition comprising a pine needle extract. The skin moisturizing composition according to the preparation method of the present invention has no skin irritation, the skin moisturizing effect lasts for a long time, and has an effect of excellent anion and far infrared ray releasing effect.

The skin is divided into three layers of epidermis, dermis, and subcutaneous fat tissue in order from the outside. However, changes in external temperature and humidity, ultraviolet rays, and pollutants, as well as excessive physical and chemical stimuli, stress, and malnutrition from the outside, seriously degrade normal functions such as moisturizing function of the skin, and reduce skin aging. It promotes and damages the skin. In order to prevent this phenomenon and maintain a healthier and more beautiful skin, efforts to maintain the unique function of the skin by using bioactive substances obtained from various animals, plants, and microorganisms are contained in cosmetics. This has been.

The skin carries about 70% of the body's water, which is a variety of bioactive substances required by the body. In addition, this moisture helps the skin to maintain a healthy state, and also plays an important role in properly controlling the evaporation of moisture in vitro. 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 the skin barrier ( J. Invest.Drmatol. 80 (Suppl.), 44-49. 1983.

The stratum corneum of the epidermis having a thickness of about 20 μm in the epidermis contains about 10-20% of moisture and is present at the outermost part of the human body, thereby suppressing evaporation of moisture from the body. It also protects the skin by blocking excessive material penetration from the outside. The surface of these stratum corneum is covered with a thin, natural protective film made of sebum from the sebaceous glands and sweat from the glands to prevent evaporation of moisture. The cells constituting the stratum corneum contain 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 effectively binds with 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 from social life, frequent skin washing due to makeup habits and natural skin The need for skin moisturizers is increasing because the moisture in the stratum corneum decreases due to various causes such as fire and the skin becomes dry, the surface becomes rough, and the skin loses shine and looks dull. To this end, a method of increasing moisture retention in the stratum corneum by using a humectant having a property of absorbing moisture or an occlusive moisturizer preventing moisture evaporation has been most widely used. Most of the humectants include polyols such as glycerin, propylene glycol, 1,3-butylene glycol, and polyethylene glycol. However, they have a drawback that is very sticky or heavy and damp due to the inherent viscosity and unique properties of the polyol when applied to the skin.

As a conventional moisturizer, a closed moisturizer is a lipid component such as ceramide or an essential fatty acid and lipid complex (J. Invest. Dermatol. (5), 731-740, 1994). There is a disadvantage in disturbing the stability to inhibit, and there is an disadvantage inadequate for producing a transparent gel-like product. 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 have limitations in that they can be used universally only in specific compositions of raw materials.

However, most of all, conventionally developed skin moisturizers can simply moisturize the skin to temporarily maintain its moisture content, but such moisturizers penetrate the epidermis and penetrate deeply into the skin. The lack of a function of fixing moisture in the stratum corneum, which acts as a barrier, has a problem that it is difficult to continuously maintain an appropriate skin moisture content. For example, Korean Patent Publication No. 10-0659138 (December 19, 2006) discloses a moisturizing cosmetic composition including gallocatechin gallate as an active ingredient. This moisturizing cosmetic composition activates the peroxysm proliferative activator receptor, promotes the expression of the skin moisturizing factor, and exerts a skin moisturizing effect. However, the moisturizing effect of this composition does not last for a long time, and there is no anion or far infrared ray emitting effect.

In addition, the Republic of Korea Patent Publication No. 2006-0067296 (2006. 06. 20. Disclosure) discloses a skin moisturizing cosmetic composition containing xylitol and beta-glucan at the same time. This skin moisturizing cosmetic composition exhibits a skin moisturizing effect by combining xylitol and beta-glucan. However, this composition also does not have an anion or far-infrared ray-releasing effect, and the skin moisturizing cosmetic composition is very poor in its ability to penetrate deeply into the skin through the epidermis and to fix moisture in the stratum corneum, and thus to an appropriate level. The problem is that it is difficult to maintain the skin moisture content continuously.

Thus, the present inventors have obtained the knowledge that when the pine needle extract extracted from pine needles is used as a skin moisturizer, the skin moisturizing effect is extremely excellent, and a skin moisturizing composition having excellent anion and far infrared ray releasing effect can be obtained, and the skin using pine needle extract The method for producing the moisturizing composition was carefully examined to arrive at the present invention.

The present invention includes the steps of preparing a pine needle liquid extract, adding vegetable ion alkaline water and castor oil to the extract and fermenting it.

According to the production method of the present invention, a skin moisturizer containing pine needle extract as an active ingredient can be prepared, and the skin moisturizing composition prepared by the production method of the present invention is excellent in skin moisturizing effect as well as anion and far infrared ray releasing effect. .

It describes the step of preparing a pine needle extract which is the first step of the present invention. Pine needles, the raw material of pine needle liquid extract, are rich in terpene-based phytoncide and generate anions by themselves, and are rich in vitamins and minerals beneficial to the human body. In addition, pine needles provide a scent of the final composition to enhance the user's satisfaction. In the present invention, the mixture comprises a pine needle liquid extract which is a liquid component recovered by crushing and filtering the pine needles.

Pine species for preparing leaf extracts include, but are not limited to, Pinus densiflora, Pinus thunbergii, Pinus pumila, Pinus rigida, Pinus banksiana, Pinus bungeana, Pinus palustris, Pinus koraiensis, Pinus sylvestris, or pinus strobus. Abies alba or Abies picea can also be used as fir species. In addition, pine extract using leaves, berries, flowers, bark, etc. of pine instead of pine needle extract may be used, it is most preferred to use pine needles.

As a process of obtaining pine needle extract, pine needles are collected in a clean area, for example, Bonghwa, Gyeongbuk, and Taebaek, Gangwon-do. It is preferable to grind | pulverize 1st grinding | pulverization and a 2nd grinding | pulverization, and grind | pulverizes to 8-10 mm or less in the 1st grinding | pulverization, and to 3-4 mm or less in the 2nd grinding | pulverization. It is preferable to steam enough after each grinding. Subsequently, the crushed pine needles are wrapped with a mesh and subjected to liquid phase separation using a hydraulic compression press, and the liquid is separated into a supernatant and a slurry when left in a standing state for more than 24 hours. The slurry is filtered to separate the supernatant, thereby obtaining a pine leaf extract. In addition to the present method, various extraction methods commonly used in the art may be used, and preferably about 1 to 15 times, preferably about 5 to 10 times, water, lower alcohols, or the like of the sample pine needle volume. A mixed solvent having a mixing ratio of about 1: 0.1 to 1:10, preferably 1: 1 to 1: 3, at about 20 to 100 ° C, preferably at about 50 to 100 ° C at an extraction temperature of about 1 hour to 2 days, preferably Preferably, about 2 hours to 1 day may be obtained using a method such as distillation, ultrasonic extraction, reflux extraction, extraction method using a supercritical fluid can also be applied. However, according to the research of the present inventors, rather than using a solvent as described above, using a series of methods of the main chain, liquid phase separation, stationary, supernatant obtained of the present invention than in the aspect of skin moisturizing effect, anion generation, far infrared generation Preferred.

The step of preparing a liquid composition using the pine needle extract of the second step of the present invention. In the present invention, the liquefied vegetable ion impregnation-alkaline ionized water is used as a solvent in order to improve the penetration into the skin and provide a moisturizing effect to the prepared skin moisturizing composition.

When water is electrolyzed, the anion-charged alkaline ionized water and the cation-charged acidic ionized water are separated. In the present invention, in order to improve penetration into the skin and provide a moisturizing effect, the nutrition cream composition is effectively fixed to the stratum corneum. The alkaline ionized water is used as the solvent. In addition, alkaline ionized water is combined with harmful oxygen (active oxygen) generated inside the human body to not only discharge to the outside of the human body but also has energy to attract various acidic wastes, thereby enhancing natural immunity.

Water is not a state in which water molecules are uniformly distributed, but is a state in which a plurality of water molecules are clustered together, and as the size of the clusters of water molecules decreases, the ability to penetrate the human body is improved. have.

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

However, as the water is highly electrolyzed and charged with a large amount of anions, the size of clusters of water molecules tends to decrease. Therefore, in the present invention, by electrolyzing the water to separate the acidic ionized water, the skin moisturizing composition is composed of alkaline ionized water having a size of 54 Hz water molecular cluster smaller than the cells of the human body as a large amount of anions are charged. do. As described above, when alkaline ionized water having a cluster size of 54 Hz smaller than human cells is charged as a solvent by highly electrolyzing water to charge an anion in large quantities, the prepared skin moisturizing composition penetrates the skin epidermis. In addition, the effect of fixing moisture to the stratum corneum and moisturizing the human skin is also greatly improved.

Castor oil and alkaline water are mixed with the pine needle extract obtained in the first step. Addition amount of pine needle extract 95 ~ 98%, castor oil 1 ~ 2.5%, liquefied vegetable-ion impregnated alkaline ionized water 1% ~ 2% is preferred. After mixing, the mixture is mixed with a homogenizer, which is preferably mixed at 2500 rpm for about 15 minutes.

The third step of the present invention is the fermentation and ripening step, it is fermented for about 60 to 80 hours at 24 ~ 25 ℃. When the fermentation is completed, the skin moisturizing composition is completed, and when applied to the skin, the skin moisturizing composition is excellent, the skin moisturizing effect is excellent, and the anion release and far infrared ray release effect is excellent.
