Description

Amethyst Cosmetic Composition And Manufacturing Method Thereof}

The present invention relates to an amethyst cosmetic composition. In detail, the present invention relates to a functional BB cream comprising an amethyst cosmetic composition prepared by finely pulverizing a natural mineral, amethyst, into nanopowder, and then dispersing it using an emulsifier, and a method for producing the same.

Modern people use chemical household goods every day, including conventional whitening cosmetics using various chemical substances. Chemicals absorbed into our body through oral inhalation, nasal absorption, and transdermal absorption are accumulated in the body. In particular, the percutaneously absorbed chemicals do not undergo liver detoxification and intestinal cleansing, so their toxicity may remain in the body. If the chemicals penetrate into blood vessels or lymph fluid, they cause illness in major organs such as the uterus, breast, and brain. I can.

In particular, the percutaneous absorption of chemical substances through the'skin' requires little attention because there is little pain and irritation, so you cannot be aware of the absorption.

In Donguibogam, amethyst (紫水晶, Amethyst) is recorded as a medicinal material that is good for infertility, strengthens the heart and intestines, improves the metabolism of the human body, stabilizes the mind, and smoothes the skin. Amethyst is a weak mineral that is determined by hydrothermal action for 60 million years, and is also called magnetoyoung (紫石英) as magma (lava) cools down during volcanic eruptions. This amethyst is a crystal of silicon (SiO ₂ , 99%) and is a far-infrared emitter material that emits 91% of far-infrared rays at room temperature (40°C) compared to other far-infrared emitters.

Since the amethyst has a mineral characteristic, it is limited to be used as a raw material for cosmetics. Amethyst has low dispersibility in a conventional cosmetic composition composed of an aqueous phase component, an oil component, and an additive such as a thickener, and is easily precipitated when used in a certain amount or more. If amethyst precipitates in cosmetics, the feeling of use decreases due to clumping when used on the skin. Therefore, in order to use amethyst as an actual raw material for cosmetics, the content of amethyst is determined only within the range in which amethyst does not precipitate. However, the content of amethyst determined according to the above criteria is only insignificant, so there is a limit to experiencing the health promotion effect of amethyst when using cosmetics.

The patent documents and references mentioned in this specification are incorporated herein by reference to the same extent as if each document was individually and clearly specified by reference.

The amethyst nanopowder refers to an amethyst nanopowder having a diameter of 0.1 to 4.5 μm by sieving with 2500 to 3500 mesh after pulverization. When the diameter exceeds 4.5 µm, dispersibility is lowered in the cosmetic composition of the present invention, so that the amethyst nanopowder may be separated and precipitated.

The functional emulsion solution contains a functional aqueous layer component and an oil layer component. The functional oil component may include aloe vera leaf water, lavender flower water, witch hazel water, western rose flower water, arbutin, and adenosine. Aloe vera leaf water, one of the cosmetic compositions, is a sap extracted by steam distillation from leaves of aloe vera plants, and has a skin soothing effect and moisturizing effect. Since the lavender flower water contains tannins, it has a skin soothing effect. In particular, it is effective in controlling sebum secretion and soothing sunburned skin. The witch hazel water is extracted from abundance and has the effect of skin protection, skin soothing, and astringent. In addition, AEC arbutin is present in bearberry, cleanberry, and bilberry, and is effective in preventing skin oxidation, skin conditioning, and skin whitening. There is.

The oil layer component may include an oil component including sunflower seed oil, jojoba seed oil, grape seed oil, tocopheryl acetate (Vit-E acetate), medium chain triglyceride, and a wax-based emulsifier. The sunflower seed oil is a natural moisturizer and has the effect of protecting dry and damaged skin. The jojoba seed oil has a skin moisturizing effect, and the grape seed oil is rich in unsaturated fatty acids, which has an antioxidant effect on the skin. In addition, the tocopheryl acetate has an effect of protecting the skin from harmful oxygen, and the medium chain fat has an effect of moisturizing the skin and preventing skin oxidation.

The wax-based emulsifier may include olive oil wax, an alkyl polyxyloxide emulsifier, or beeswax. Preferably, the olive oil wax may be PEG-4 olivate (olivem ^® 1000), and the alkyl polyxyloxide emulsifier is octyldodecanol/octyldodecyl xyloside (Octyldodecanol/Octyldodecyl Xyloside) or PEG-30 di It may be polyhydroxystearate (PEG-30 Dipolyhydroxystearate, EasyNov ^™ ). In particular, the beeswax is excellent in dispersing amethyst nanopowder compared to the olive oil wax and the alkyl polyxyloxide emulsifier. The beeswax is completely dissolved at a temperature of 70 to 80 °C, and after coating the amethyst nanopowder, it is solidified in the process of slowly stirring and cooling to 30 to 40 °C to more tightly coat the amethyst nanopowder. In contrast, the effect of improving the dispersibility of amethyst is excellent. Therefore, the wax-based emulsifier of the present invention optimizes the dispersibility of the amethyst nanopowder by appropriately controlling other emulsifiers based on the beeswax.

The amethyst dispersion solution is preferably prepared by adding the amethyst nanopowder to a functional emulsion solution of 70 to 80° C. and then slowly stirring and cooling from room temperature to 30 to 40° C. In particular, if the initial temperature of the functional emulsion solution is less than 70°C or the temperature after cooling exceeds 40°C, the effect of improving the dispersibility of the amethyst nanopowder by the wax-based emulsifier is insignificant. Even if the cooling rate is too fast, the wax-based The effect of improving the dispersibility of the amethyst nanopowder by the emulsifier may be reduced. In addition, the cooling rate is preferably cooled while stirring at room temperature of 25 to 35 ℃.

The amethyst cosmetic composition of the present invention may be prepared by adding BB cream powder to the amethyst dispersion solution to prepare an amethyst cosmetic composition for BB cream.

The amethyst cosmetic composition of the present invention may contain 20 to 30% by weight of amethyst nanopowder dispersed by a functional emulsion solution containing a wax component. Preferably it may contain 22 to 28% by weight of the amethyst nanopowder, and more preferably 25% by weight of the amethyst nanopowder. When the content of the amethyst nanopowder is less than 20% by weight, the amount of thermal infrared and anion emission is insignificant, and the resulting skin improvement effect is insignificant.When the content of the amethyst nanopowder exceeds 30% by weight, the amethyst nanopowder is separated from the emulsion solution. As it precipitates, there is a risk of deteriorating the feeling of use.

The present invention will be described in detail through the following examples and experimental examples.

Example

Example: Amethyst cosmetic composition for BB cream and preparation thereof

A cosmetic composition for BB cream containing amethyst powder was prepared.

The cosmetic composition for BB cream includes amethyst nanopowder that has an antimicrobial effect by radiating far-infrared rays, increases blood flow by preventing aggregation of red blood cells, and reduces skin fatigue. Since the amethyst is a crystal of silicon, it is not dispersed as a general liquid and sinks. If the amethyst is not dispersed and is settled, there is a problem in that the feeling of use of cosmetics is deteriorated and consumer preference is lowered.

Therefore, in the present invention, a functional emulsion having an optimal composition was prepared so as not to settle by dispersing the amethyst powder in an optimal manner. In addition, a cosmetic composition containing amethyst powder that can improve the efficacy of the amethyst while meeting consumer preferences was prepared using the amethyst emulsion.

The composition of the cosmetic composition for BB cream containing the amethyst powder is shown in Table 1 below.

The cosmetic composition of the present invention is prepared according to the steps of preparing a functional aqueous layer solution, preparing a functional amethyst dispersion solution, and preparing an amethyst cosmetic composition.

First, the functional aqueous layer solution was mixed as shown in Table 1 according to the above Aloe vera leaf water, lavender flower water, witch hazel water, western rose flower water, AEC Arbutin, and Adenosine according to each example, and then at 70 to 80 ℃ for 10 to 15 minutes. It was prepared by a method of dissolving by stirring at 500 rpm.

The functional amethyst dispersion solution was prepared by preparing an emulsion solution containing oil and then adding amethyst nanopowder and BB cream powder. As the amethyst nanopowder, only amethyst nanopowder passed through 3000 mesh after pulverizing the amethyst was used. The 3000 mesh refers to a mesh having 400 inches and 3000 inches (400 x 3000) vertically and horizontally (vertical x horizontal), respectively. Therefore, the amethyst nanopowder passing through the mesh is an amethyst nanopowder having a diameter of 4.5 μm or less. If the size of the amethyst particles is too large, there is a concern that amethyst powder may precipitate, and the amethyst particles may be aggregated in a dispersion process where the size of the amethyst particles is too small, so that precipitation may be promoted. Therefore, in the present invention, the above problem is solved by using amethyst nanopowder having a diameter of 4.5 μm or less.

The functional amethyst dispersion solution is prepared by first adding an emulsifier to an oil component. The oil component was mixed as shown in Table 1 according to each example, and the emulsifier was further mixed.

The oil components are sunflower seed oil, jojoba seed oil, grape seed oil, tocopheryl acetate (Vit-E acetate), and medium chain triglyceride.

The emulsifiers are olive oil wax (PEG-4 olivate, olivem ^® 1000), alkyl polyxyloxide emulsifiers (octyldodecanol/octyldodecyl xyloxide/Pig-30 dipolyhydroxystearate, Octyldodecanol/ Octyldodecyl Xyloside/PEG-30 Dipolyhydroxystearate EasyNov ^™ ) alc beeswax.

The mixed oil component and emulsifier were heated to 70 to 80 °C to dissolve the oil component and the emulsifier to prepare an emulsion solution. A functional amethyst dispersion solution was prepared by slowly adding the amethyst nanopowder and the BB cream powder to the emulsion solution and stirring at a speed of 800 to 11000 rpm for 15 to 20 minutes.

The prepared functional amethyst dispersion solution was stirred at a speed of 800 to 11000 rpm and the temperature was slowly lowered to 35° C. at room temperature without stopping the stirring.

The wax-based emulsifier is completely dissolved in the prepared functional amethyst dispersion solution at 70 to 80° C. to form a solution. Therefore, in the functional amethyst dispersion solution under the above temperature condition, the amethyst powder is sufficiently coated with the wax component of the solution. When the temperature of the functional amethyst dispersion solution is gradually lowered and reaches a level of 35°C, the microenvironment around the amethyst nanopowder changes according to the change in the properties of the wax. At this temperature, the wax emulsifier existing in the microenvironment around the amethyst nanopowder changes from a solution state to a semi-solid state. Therefore, the amethyst nanopowder is coated with a semi-solid wax instead of a solution wax. The amethyst nanopowder coated with the semi-solid wax component is maintained without being affected by changes in external conditions. Therefore, the functional amethyst dispersion solution of the present invention has the advantage that the wax coating on the amethyst nanopowder is solid at the temperature or lower, so that the dispersion state is continuously maintained. Among the wax-based emulsifiers used in the present invention, the beeswax is judged to have the best dispersion effect of the amethyst nanopowder by the above mechanism.

While maintaining the temperature and stirring of the functional amethyst dispersion solution, the additive component and the fragrance component of Table 1 were sequentially added to prepare an amethyst cosmetic composition for BB cream. Among the additive components, AT100P was used as a thickener and DPG (dipotassuim glycyrrhizinate) was used as a solubilizer. In addition, the sodium hyaluronate was used as a skin moisturizer. Among the fragrance components, 1,2 nucleic acid diol (1,2-Hexanediol) was used as a fragrance component to inhibit the oxidation of cosmetics and the reproduction of microorganisms.

If the fragrance component is added first, the fragrance may disappear during the stirring process, so it is important to add the additive first to adjust the properties of the functional amethyst dispersion solution to the final amethyst cosmetic composition for BB cream and then add the fragrance Do.

After adding the additive component to the functional amethyst dispersion solution, stirring was added for 20 to 25 minutes, and then the fragrance component was slowly added and stirred for 10 to 15 minutes to prepare an amethyst cosmetic composition for BB cream. The prepared amethyst cosmetic composition for BB cream was degassed, filtered, and then aged for at least 24 hours and stored.

Experimental Example 1: Stability evaluation of an amethyst cosmetic composition for BB cream

The cosmetic composition of the present invention contains amethyst powder. The amethyst powder has a low dispersibility and is separated when used a lot, thereby reducing the feeling of use of the cosmetic composition.

The present invention confirmed the conditions in which the amethyst powder was optimally dispersed and not separated through formulation testing. The amethyst powder was based on the content of 25% by weight based on the total cosmetic composition, and the degree of dispersion was improved by adjusting the oil component layer. First, the formulation test was repeated by adjusting the oil components such as sunflower seed oil, jojoba seed oil, argan oil, grape seed oil, Vit-E acetate, and MCT, which are oil components. As a result of the experiment, it was confirmed that the amethyst powder was separated from the formulation in all cases where 25% by weight of the amethyst powder was contained. Next, the formulation test was repeated by adjusting the viscosity modifier or the emulsion stabilizer. As the viscosity modifier or emulsion stabilizer, an olive-derived natural emulsifier (olive emulsion wax, olivem ^® 1000), beeswax or candelina wax (alkyl polyxyloxide emulsifier, EasyNov ^® ) was used. As a result of the experiment, it was confirmed that beeswax is most effective in dispersing amethyst powder compared to other waxes and emulsifiers. In addition, it was confirmed that the dispersibility of amethyst powder is improved only when an appropriate amount is used in the case of candeli or wax. In particular, it was confirmed that the amethyst powder was most excellently dispersed in Example 2. Therefore, the composition of the viscosity modifier or emulsion stabilizer of the oil component layer that best improves the dispersibility of the amethyst powder is a natural emulsifier derived from olive: beeswax: candelina wax = 4% by weight: 3% by weight: 0.5% by weight Was confirmed to be added.

The reason why the beeswax plays a major role in the dispersion of the amethyst powder is considered to be due to the characteristics of changes in physical properties depending on the temperature of the beeswax. The beeswax has a property of hardening at room temperature. Therefore, the beeswax is dissolved when mixed (70 to 80°C) and hardened during cooling after coating the amethyst powder. Therefore, even when cooled, the emulsification of the amethyst powder is not released, but the amethyst powder is not exposed to the aqueous layer of the solution because it hardens and holds it.

Experimental Example 2: Far-infrared emission evaluation of an amethyst cosmetic composition for BB cream

The amount of far infrared rays emitted from the amethyst cosmetic composition for BB cream of the present invention was measured. As the test method, the KFIA-FI-1042 standard test method of the Korea Far Infrared Association was used, and the emissivity and radiant energy were measured at a temperature of 37 ℃. The test method was performed by using an FT-IR spectrometer and comparing the black body measurement value. The emissivity refers to a ratio of energy re-emitted when an object absorbs external light energy and then partially re-emits or when a surface reflection phenomenon occurs. The radiation energy refers to energy emitted from an object, and energy transmitted in the form of an electromagnetic wave includes infrared rays, visible rays, and ultraviolet rays.

As a result of the experiment, it was confirmed that the amethyst cosmetic composition for BB cream of the present invention had an emissivity of 5 to 20 ㎛ and an emissivity of 89.2% when the temperature was 37 ℃, and the radiation energy was 3.44 x 10 ² W/m ² ·㎛. (See Fig. 2). According to prior research of the present inventor, when the radiation amount is measured for the same amount of amethyst powder, the radiation amount is 5 to 20 µm, the emissivity is 89.5% when the temperature is 37 °C, and the radiation energy is 3.45 x 10 ² W. It is confirmed to be /m ² ·㎛. Therefore, the amethyst cosmetic composition for BB cream of the present invention is judged to have the same level of radiation energy properties as the amethyst powder because the amethyst powder is well dispersed and there is no aggregation.

In order to confirm the change in skin temperature due to the far-infrared emission of the amethyst cosmetic composition for BB cream of the present invention, the change in skin temperature before and after the use of the amethyst cosmetic composition for BB cream of the present invention was conducted for female experimenters in their 30s and 50s. It was measured and analyzed with a thermal imaging camera.

As a result of the experiment, it was confirmed that the skin temperature of the face was increased when the amethyst cosmetic composition for BB cream of the present invention was used (see FIG. 3). The above result is considered to be because the amethyst nanopowder contained in the amethyst cosmetic composition for BB cream of the present invention emits far infrared rays. Far-infrared rays emitted from amethyst remove harmful bacteria present in the skin and increase skin temperature, so it is believed that skin troubles caused by bacteria decrease and blood vessels expand, increasing blood flow. Therefore, it is expected that harmful bacteria on the skin will be reduced, and skin nutrition and oxygen supply will be improved, improving skin condition and improving wrinkles.

Experimental Example 3: Evaluation of anion emission of amethyst cosmetic composition for BB cream

The amount of anions released from the amethyst cosmetic composition for BB cream of the present invention (Example 2) was measured. Negative ions are generally known to have the effect of improving blood flow, increasing brain oxygen flow, promoting brain activity, promoting human metabolism, and enhancing immune function. In particular, in skin health, the negative ions are effective in inhibiting active oxygen, slowing skin aging, and strengthening collagen to maintain skin elasticity and volume. In addition, it has the effect of improving skin health by enhancing skin immunity. The amount of anions released from the amethyst cosmetic composition for BB cream of the present invention was tested using the KFIA-FI-1042 method of the Korea Far Infrared Application Evaluation Research Institute (Korea Far Infrared Association). In the test, 5 g of an amethyst cosmetic composition for BB cream was used, and the amount of anions released was measured using a charge emission measuring device under the conditions of an indoor temperature of 26° C., a humidity of 45%, and an anion number of 108/cc in the air. The measured anions were expressed as the number of ions per unit volume.

Table 2 shows the results of measuring the amount of anions released from the amethyst cosmetic composition for BB cream of the present invention. As a result of the test, it was confirmed that it showed an improved amount of anion emission compared to the anion water in the atmosphere.

sample Amount of anion (ION/cc) Anion water in the air 108 Amethyst cosmetic composition for BB cream (Example 2) 114

Experimental Example 4: Evaluation of antibacterial test of amethyst cosmetic composition for BB cream

The amethyst cosmetic composition for BB cream of the present invention (Example 2) contains 25% by weight of amethyst nanopowder. The amethyst nanopowder has an effect of emitting far infrared rays and negative ions. Therefore, the amethyst cosmetic composition for BB cream of the present invention is expected to improve the antibacterial effect by the far infrared rays and anions.

To confirm this, the antibacterial effect of the amethyst cosmetic composition for BB cream of the present invention was tested through the Korea Far Infrared Application Evaluation Research Institute (Korea Far Infrared Association). For the test, test method KFIA-FI-1002 was used, and E. coli (E. Coli, ATCC 25922), and Staphylococcus (S. Aureus, ATCC 6538) were used. The culture medium was tested by measuring the number of microorganisms increased or decreased compared to the initial concentration of microorganisms in a culture medium containing a blank and an amethyst cosmetic composition for BB cream. The number of bacteria on the medium was calculated by multiplying the dilution factor.

Table 3 and Figure 4 shows the antibacterial effect test results for the amethyst cosmetic composition for BB cream of the present invention. As a result of the test, it was confirmed that the antibacterial effect against E. coli and staphylococcus was excellent when the amethyst cosmetic composition for BB cream of the present invention was used. The above effect is judged to be due to the antibacterial effect of far-infrared and negative ions released from the amethyst contained in the amethyst cosmetic composition for BB cream.

Experimental Example 5: Test for change of red blood cell status due to amethyst cosmetic composition for BB cream

The change in the state of red blood cells due to the far-infrared emission of the amethyst cosmetic composition for BB cream of the present invention (Example 2) was tested. Through the above experimental examples, it was confirmed that the amethyst cosmetic composition for BB cream of the present invention emits far-infrared rays, thereby increasing the skin temperature. When the skin temperature rises, blood flow increases, thereby improving the supply of nutrients and oxygen to the skin, thereby improving the skin condition. In order to confirm the change in the state of blood due to the amethyst cosmetic composition for BB cream of the present invention, the change in the state of red blood cells was tested.

First, blood was collected from the index finger of the subject who did not apply the amethyst cosmetic composition for BB cream of the present invention, and a picture of the red blood cells was taken under a microscope, and 30 minutes elapsed after applying the amethyst cosmetic composition for BB cream of the present invention to the index finger of the subject. After that, blood was collected again and red blood cells were photographed.

As a result of the experiment, it was confirmed that the cluster of red blood cells was released, and it was confirmed that the shape of the red blood cells returned to a healthy round circle (see FIG. 5). Therefore, when the amethyst cosmetic composition for BB cream of the present invention is used, the aggregation of red blood cells is released and blood flow is smoothed, so it is determined that the supply of nutrients and oxygen to the skin will be smooth.

Experimental Example 7: Feeling test of amethyst cosmetic composition for BB cream

For the amethyst cosmetic composition for BB cream of the present invention (Example 2), the feeling of use of the evaluator was tested. The composition of the present invention contains 25% by weight of amethyst nanopowder. Since amethyst is a mineral containing silicon (Si) as its main component, it has low dispersing power and is likely to exist in a precipitated state in a solution. When the amethyst nanopowder is settled in a precipitated state, clumping occurs when used on the skin, resulting in a rough feeling, thus reducing the feeling of use.

The amethyst cosmetic composition for BB cream of the present invention improved the stability (dispersibility) of the amethyst nanopowder by using amethyst nanopowder and preparing an optimum emulsion solution. For the amethyst cosmetic composition for BB cream of the present invention, 21 trained testers to use the composition of the present invention to use the composition of the present invention in order to confirm the feeling of use by the actual user, and the items of texture, spreadability, moisture, absorption, fragrance and overall feeling I made them score. The score was given a score of 5 points according to each level of feeling. Table 7 shows the results of the feeling test.

Item Average score S.D. The texture of the formulation 3.76 0.83 Formulation application 4.05 0.74 Moisture of the formulation 4.33 0.58 Formulation absorption 4.10 0.77 Formulation fragrance 2.81 0.60 Overall feeling of use of the formulation 3.95 0.67 SD: Standard deviation, ^* : p <0.05 by paid t-test
Score: 1 point: Very bad. 2 points: Not good. 3 points: Moderate. 4 points: Good. 5 points very good.

As a result of the test, it was confirmed that the formulation received excellent evaluation in terms of spreadability, moisture, and absorption, and the overall feeling of use was also confirmed to be excellent. This is believed to be because the dispersion degree was excellent even though the amethyst powder was used at 25% weight.

The specific embodiments described herein are meant to represent preferred embodiments or examples of the present invention, and the scope of the present invention is not limited thereby. It will be apparent to those skilled in the art that variations and other uses of the invention do not depart from the scope of the invention described in the claims of this specification.
