Description

Technical Field

[0001] The present invention relates to a cosmetic composition, which uses fermentation microorganisms to prepare fermented clay minerals or a complex thereof, and applies the prepared complex to a cosmetic composition for skin cleansing, thereby improving the cleaning power of the cosmetic composition containing the clay minerals against pollutants such as fine dust or heavy metals. Background Art

[0002] The material suspended in the atmosphere is called dust, and particles of a size that cannot be seen with the naked eye are called fine dust. Fine dust is classified by particle size and is divided into PM10 (fine dust with a diameter of 10μm or less) and PM2.5 (ultrafine dust with a diameter of 2.5μm or less) according to its size. The components that make up fine dust may vary depending on the region where fine dust is generated, or the season and weather conditions. Generally speaking, fine dust is generated by exhaust gases such as factory and automobile exhaust and the combustion of fossil fuels (coal, oil), and is composed of ion components such as sulfates, nitrates, and ammonium, as well as various harmful substances such as carbon compounds and metal compounds.

[0003] Recently, fine dust, one of the causes of skin damage, has been reported to cause dehydration, fine lines and wrinkles in the short term, and in the long term, it causes the skin barrier to lose its protective function and induces various skin diseases such as skin cancer. In particular, ultrafine dust with a diameter of less than 2.5 μm is about 20 times smaller than the skin pores, so it can easily penetrate into the skin pores through the hair follicles. If fine dust penetrates the skin, it will produce active oxygen, damage the mitochondria of the skin, reduce collagen synthesis, increase decomposition, and stimulate melanocytes to induce pigmentation, which may accelerate skin aging phenomena such as pigmentation, wrinkles and pore dilation.

[0004] Therefore, if the attached fine dust is not completely removed, there is a high probability that it will cause an inflammatory reaction in the skin pores, thereby causing skin problems, so it is very important to remove the fine dust and prevent it from penetrating into the skin. However, for ultra-fine dust with a small particle size, it is difficult to completely remove the fine dust that has penetrated deep into the pores due to its strong skin adsorption, and there is little research on how to effectively and easily remove fine dust accumulated in the body or on the skin surface.

[0005] In addition, cosmetics using natural substances as raw materials have attracted much attention because they can be both functional and safe. Natural substances refer to plants, animals, minerals, microorganisms and their metabolites obtained from nature, among which minerals can be purified and added to cosmetics in the form of powders and gels. However, mineral raw materials have a stacked structure due to the strong van der Waals attraction between plates, so there is a problem of poor dispersion stability of the continuous phase due to the aggregation phenomenon between particles. Therefore, it is necessary to develop a technology to improve dispersion stability so that mineral raw materials can be stably applied to dosage forms.

[0006] In view of this, the present inventors aim to provide a material of a nano-sized plate-like clay mineral and a composite thereof having a dust removal effect, wherein the dispersibility is improved by a fermentation process in which enzymes possessed by microorganisms decompose organic matter.

[0008] Non-patent literature

[0009] Non-patent literature 0001: Sangwook Lim, Darsh Wasan, “Structural disjoining pressure induced solid particle removal from solid substrates using nanofluids”, Journal of Colloid and Interface Science, Vol. 500, 2017, pp. 96-104, ISSN 0021-9797. Summary of the invention

[0010] Problems to be solved by the invention

[0011] In order to solve the above problems, the purpose of the present invention is to provide a skin cleansing cosmetic composition, which has excellent dispersibility and utilizes the wedge film principle formed by clay minerals with nanoplate structures fermented by microorganisms, and has excellent cleaning power especially for pollutants such as heavy metals and / or fine dust.

[0012] Solutions for solving problems

[0013] The inventors of the present invention used microorganisms to ferment clay minerals such as hectorite and bentonite, which are used as emulsifiers and adjuvants in cosmetic raw materials, thereby reducing the aggregation of mineral raw material particles and improving dispersion stability. Figure 1 As shown, it can be confirmed that the prepared nano-sized plate-like fermented clay mineral acts between the skin surface and the attached dust, thereby improving the removal efficiency of pollutants such as heavy metals and / or dust attached to the skin through the wedge film (Wedge Film) formed in the space between the solid surface and the solid particles, and exhibiting an excellent cleaning effect, thereby completing the present invention.

[0014] Wedge Film refers to the space between the solid surface and the solid particles formed by nanoparticles, which uses the principle of causing solid particles to fall off the solid surface based on the repulsive energy per unit area, and can help remove pollutants such as heavy metals and / or dust attached to the skin.

[0015] To this end, the present invention provides a skin cleansing cosmetic composition comprising (1) a fermented clay mineral, or (2) a complex of the fermented clay mineral, purified water, and a glycol.

[0016] The clay mineral of the present invention can be any one of natural substances, purified products of natural substances or synthesis, without particular limitation, and examples thereof include: kaolinite clay minerals, such as kaolin, nacrite, dickite and halloysite, etc.; antigorite clay minerals, such as antigorite and cronstedite, etc.; and smectite clay minerals, such as bentonite, montmorillonite, beidellite, nontronite, saponite, hectorite and stevensite, etc. These components can be used alone or in combination of two or more. Specifically, the above-mentioned clay mineral can be a smectite clay mineral, and more specifically, the above-mentioned clay mineral can be hectorite.

[0017] The clay mineral of the present invention is a fermented clay mineral, and the microorganism used for the fermentation may be one or more microorganisms selected from the group consisting of Saccharomyces cerevisiae, Lactobacillus plantarum, Lactobacillus rhamnosus and Rhodobacter capsulatus. In the process of fermenting the clay mineral by the fermentation microorganism, the aggregation phenomenon of the mineral particles is improved, so when the fermented clay mineral is applied to the cosmetic dosage form, the dispersibility of the composition can be further improved compared with the case of using the unfermented clay mineral, thereby helping to form a uniform wedge-shaped film between the skin and the pollutants.

[0018] Furthermore, the fermented clay mineral is prepared and used in a form suitable for use in a cosmetic composition, and specifically, can be prepared and used in a powder or gel form.

[0019] In a specific embodiment of the present invention, the fermented clay mineral can be prepared into a cosmetic composition in the form of a gel-like complex by a method comprising the following steps:

[0020] (1) A step of mixing the clay mineral raw material with purified water;

[0021] (2) then, inoculating a fermentation microorganism and performing a fermentation step; and

[0022] (3) A step of mixing and dispersing a diol and purified water in the fermented clay mineral raw material.

[0023] The order of the above steps (2) and (3) can be changed. Step (3) can be performed first to disperse the clay mineral in the glycol and purified water to prepare a gel, and then ferment the mixture by inoculating the fermentation microorganism. When inoculating the fermentation microorganism, inoculation in the liquid phase is more conducive to the dispersion of the microorganisms than inoculation in the solid phase, thereby making the fermentation more uniform. Therefore, it may be more preferable to inoculate the microorganisms after preparing the gel.

[0024] The gel-like composite prepared above can be freeze-dried and then pulverized to form a powder.

[0025] The mixing step in the above step (1) can be carried out at 40°C to 60°C, and the fermentation step in the above step (2) can be carried out at 25°C to 40°C.

[0026] The clay mineral raw material, fermentation microorganism and diol used to prepare the composite may be used in an amount of 3-10 wt %, 1-5 wt % and 1-5 wt % respectively relative to the total weight of the composite.

[0027] If the clay mineral fermented according to the method of the present invention is prepared into a gel-shaped composite form, when it is applied to various dosage forms, it can be dispersed better than when it is prepared in a powder form. In addition, in the case of powder, when it is applied to a dosage form, since the stirring process in the water phase for several minutes is added, there are disadvantages of low efficiency in terms of time and cost in the preparation process and clinical trials.

[0028] The fermented clay mineral or the fermented clay mineral composite of the present invention may account for 0.1 wt % to 40 wt %, preferably 1 wt % to 20 wt %, and more preferably 1 wt % to 10 wt % relative to the total weight of the cosmetic composition. When the content of the fermented clay mineral or the composite thereof is less than 0.1 wt %, the cleaning effect on fine dust is not obvious, and when the content exceeds 40 wt %, there is a problem of poor long-term stability.

[0029] The skin cleansing cosmetic composition comprising the fermented clay mineral or the complex thereof according to the present invention has excellent dispersibility, and thus can enhance the cleansing effect of pollutants present on the skin. The pollutants may be fine dust and / or heavy metals.

[0030] Therefore, the cosmetic composition of the present invention may be a cosmetic composition for cleansing skin, and specifically, may be a cosmetic composition for cleansing fine dust and / or heavy metals.

[0031] In addition, the cosmetic composition of the present invention can be prepared into dosage forms that can be used as all forms of cosmetics, and can be prepared into dosage forms such as lotions, essences, emulsions, creams, primers, hard soaps, liquid soaps, foundation liquids, foam cleansers, cleansing lotions, cleansing creams, cleansing towels, cleansing water, shower gels and hand soaps, shampoos, hair dyes and hair treatment creams for washing purposes.

[0083] <Experimental Example 1. Measurement of Transmission Electron Microscope (TEM) Images of Hectorite and Fermented Hectorite Raw Materials>

[0084] Figure 2 The results of measuring the particle morphology of the raw materials in Preparation Example 1 and Preparation Example 2 using a transmission electron microscope (TEM) (JEOL JEM-2100PLUS, Japan) are shown in FIG. Figure 2 (a) and Figure 2 As shown in (b), it was confirmed that, unlike the aggregated conventional hectorite, the fermented hectorite was well dispersed and had a nano-sized plate-like structure.

[0085] <Experimental Example 2. Zeta Potential Analysis of Hectorite and Fermented Hectorite Raw Materials>

[0086] Surface potential was measured. For this analysis, zeta potential analysis was performed using electrophoresis. However, since the measurement environment used for the analysis is very diverse and there are many external conditions that need to be controlled, such as the type of solvent, temperature, pH value, etc., the zeta potential was measured by treating the sample under the same conditions. For the set conditions, the sample was analyzed by diluting it to 1 / 1000 using pure water as a solvent, and the measurement temperature was fixed at 25°C. The analysis results are as follows Figure 3 shown.

[0087] The test results showed that the hectorite raw material showed a charge of about -39 mV, while the fermented hectorite raw material showed a charge of about -44 mV. This confirmed that the fermented hectorite raw material had the largest surface charge, and thus the dispersion stability could be improved.

[0088] <Experimental Example 3. Evaluation of dust cleaning power of water, hectorite composite, and fermented hectorite composite>

[0089] During the preparation stage, the test site was kept clean and dry to provide the same measurement conditions for the subjects, and the skin was allowed to stabilize for at least 30 minutes in a place where constant temperature and humidity (22±2°C, RH40-60%) could be maintained. Carbon black powder with an average particle size of less than 10 μm was used as a dust substitute simulant, and hectorite complex and fermented hectorite complex were used to evenly apply to the test site. After preparing a 10% concentration by adding carbon black powder to pure water and mixing, the test product was added at 2 mg / cm using a micro pipette. 2 The amount was applied to the selected test site (3cm×3cm) in the forearm. Water, hectorite complex (gel) and fermented hectorite complex (gel) were applied to each divided test site, rubbed 3 times, and then cleaned with running water for 2-3 seconds. For the measurement, a total of 3 measurements were carried out, namely before applying the carbon black powder, after applying it, and after cleaning with water, and the 3 values ​​were used to calculate the average value. The test site was photographed with a high-resolution digital camera (Digital Camera) (Canon EOS 50D, Japan), and the brightness (intensity) value or pixel (pixel) value of the test site was analyzed using an image analysis program to obtain the adsorption amount after applying the dust and after cleaning. The photos were taken under constant illumination and the same conditions, and the results of the analysis of the amount of dust adsorption showed that if the brightness value increased or the pixel value decreased, it means that the dust adsorption decreased. Therefore, when the adsorption amount of the test product treated group showed a statistically significant (p < 0.05) decrease compared to the adsorption amount of the untreated group, it was judged to have the effect of preventing dust adsorption.

[0090] Test results, such as Figure 4 As shown, it was confirmed that the fermented hectorite complex reduced the amount of fine dust adsorbed on the skin by 42.7% compared with the conventional hectorite complex, and thus had a more excellent fine dust cleaning effect.

[0091] <Experimental Example 4. Evaluation of dust cleaning power of water, cream without hectorite complex, cream with hectorite complex, and cosmetic composition (cream) with fermented hectorite complex>

[0092] The fine dust cleaning ability was evaluated in the same manner as in Experimental Example 3.

[0093] Test results, such as Figure 5 As shown, it was confirmed that the cream using the fermented hectorite complex (Example 1) had the most excellent dust cleaning effect at 80.8% compared with the cream without the hectorite complex and the cream using the hectorite complex (Comparative Examples 1 and 2).

[0094] Experimental Example 5. Evaluation of dust cleaning power of water, foam cleansing milk without hectorite complex, foam cleansing milk with hectorite complex, and cosmetic composition (foam cleansing milk) with fermented hectorite complex

[0095] The fine dust cleaning ability was evaluated in the same manner as in Experimental Example 3.

[0096] Test results, such as Figure 6 As shown, it was confirmed that the foam cleansing milk using the fermented hectorite complex (Example 2) had the most excellent dust cleaning effect at 90.7% compared with the foam cleansing milks without the hectorite complex and the foam cleansing milks using the hectorite complex (Comparative Examples 3 and 4).
