Description

Manufacturing method of lava seawater-derived minerals and dermabiotics-derived nucleotides and functional dermabiotics cosmetic composition using the mineral-nucleotides and functional dermabiotics cosmetic composition using the mineral-nucleotide }

The present invention is useful for solving both intrinsic factors and extrinsic factors of skin aging at the same time, useful skin microorganisms (dermabiotics, dermabiotics) are used as culture water for lava sea water rich in natural mineral content. After cultivation at high concentrations, the cells are recovered, and lava seawater mineral concentrated water is cultivated to generate a large amount of mineral-nucleotides in the cells, and heat-pressure extraction method is used to prepare a mineral-nucleotide conjugate having excellent thermal stability. It is about. In the present invention, after thermal pressure extraction, a method of purifying mineral-nucleotides by selectively removing cell wall components (cell walls, glycolipids, lipid proteins, etc.) that cause inflammatory reactions of skin cells through cooling centrifugation through membrane filtration methods Provided, Dermabiotics-derived mineral-nucleotide conjugate cultured in lava seawater thus prepared is thermally stable and suggests that it has the function of regulating the skin micro-biome, the third skin layer, and the expression of functional proteins related to skin barrier strengthening. do.

The skin is composed of three layers of epidermal layer, dermal layer, and stratum corneum. The epidermal layer is directly under the stratum corneum and is responsible for the function of permeation barrier, innate immunity, protection against ultraviolet rays, wound healing, and synthesis of vitamin D. The dermal layer is the epidermis. It is a layer responsible for supplying nutrients to the skin and regenerating the skin. The outermost stratum corneum in the skin structure is formed of a very thin layer about 0.5 mm thick. The stratum corneum composed of 25 to 30 dead skin cells serves to protect our skin and the differentiation of keratinocytes is the division of basal cells-synthesis in polar cells-autolysis in granule cells-in keratinocytes It consists of 4 stages of the rebuilding process of and forms a skin barrier. In the process of forming this skin barrier, cell regeneration occurs for about 4 weeks based on young skin. Skin protects the human body from physical and chemical stimuli from the outside, but when exposed to ultraviolet rays, a representative external factor of skin aging, it damages the DNA of skin cells and releases reactive oxygen species (ROS). To inhibit the collagen synthesis of the skin and accelerate the decomposition, thereby aging the skin to create wrinkles. Although it is accepted as the theory of natural aging that the internal factors of skin aging depend on genetic factors inherited from parents, the rate and condition of skin aging due to changes in skin microbiome called the third skin layer Is different.

In addition, there have been statistically confirmed reports of differences in skin condition and type according to region, race, and age. Kompaore et al. (Skin Pharmacol., 1993;6: 200-207) reported percutaneous moisture loss in Asians, Caucasians and African Americans, and reported that Asians and African Americans were higher than Caucasians. Skin Pharmacol.Physiol.,200;22:190-199) measured sebum levels by age group in Chinese men and women, and women's foreheads had lower sebum levels than men's foreheads, and women tended to decrease significantly after their 30s. However, males reported similar tendencies until their 50s, and then gradually decreased. Marrakchi et al. (Contact dermatitis, 2007; 57:28-34) compared the moisture content and sebum content of young people aged 24 to 34 with those aged 66 to 83. As a result, the moisture content of young people was higher than that of older people on the forehead and cheeks. The amount of sebum was reported to have no significant difference between the young and old.

According to the national skin characteristics bank construction business report, in the case of Koreans, female skin types were in the order of complexity>dry>neutral>oily, and male skin types were in the order of oily>complex>neutral>dry.

Skin microbiome, which has been spotlighted as a topic of recent research, refers to the ecosystem of the flora that is distributed in the skin, and is mainly present in the skin of the genus Staphylococcus , Propionibacterium , etc. It is reported that microorganisms maintain a healthy skin condition by maintaining a balance through interaction with skin cells. The skin flora that constitutes the skin microbiome varies depending on the age group, woman and man, race, and region of residence, and it is reported that skin dominant species by age group maintain skin health.

Recently, with the development of cosmetics using microorganisms as a core material in the industry, the microorganisms are manufactured in lysate and used in cosmetics to avoid skin penetration problems caused by microbial size, problems caused by preservatives, and competitive inhibition problems. It was intended to improve skin barriers by directly reacting with immunoreceptors. Of using a commercially available microbial material Bifidobacterium (Bifidobacterium) in or Lactobacillus bacteria (Lactobacillus) There are commercially available as the material used for the genus of lactic acid bacteria to the skin of which, bipyridinium the lactic acid bacteria cell lysate Examples include fermentation concentrate representative It has as a main component. However, among the cell components, peptidoglycans (peptidoglycan), glycolipids (lipopolysaccharide), and lipoproteins, which are known to cause an immune reaction with the skin, are present in the cell wall. , May cause skin problems such as erythema. In addition, since the thermal stability of bacterial nucleotides, which are active ingredients in the cytoplasm, is 70-105°C based on the Tm value (the temperature at which the DNA double helix is released), it is an effective ingredient to apply at least 121°C, the temperature that can completely break the cell wall. It becomes denatured and does not help improve the skin barrier. In addition, one of the problems in the application of the microbial material for skin protection is that it is not a selective growth factor for the skin bacterial flora when applying cell debris to the skin, so if harmful skin is used as a growth nutrient, healthy skin micro The balance of the biome is broken. Various microbial cell debris currently listed as ingredients for international cosmetics do not solve the imbalance problem of skin microbiome because they contain a large amount of the components of the regulator unit that can affect human skin microbiome.

Lava seawater is water that has been aged for a long time as the seawater is naturally filtered into basalt and sandy layers and matured for a long time.It is a unique water resource possessed only by Jeju Island. In Jeju, lava seawater has been developed from the characteristics of low temperature and cleanliness of lava seawater since 1980s. Has been actively used as a breeding water for halibut farming, and has been in the spotlight since it was used as water for saunas in terms of health and beauty since 5-6 years ago. Depending on the purpose of use, lava seawater may be used as desalted lava seawater from which salt has been removed or as it is collected.

Lava seawater contains more essential minerals (sodium, manganese, zinc, molybdenum, selenium, etc.) as well as essential minerals such as sodium, magnesium, calcium, and potassium than ordinary seawater, deep water, and samdasoo water. Among them, vanadium, which is known to stabilize insulin secretion or improve diabetes, hyperlipidemia, etc., promote blood circulation, enhance immunity, germanium with anticancer activity, inhibit oxidation of fat, synergistic effect to maintain heart and liver, radical scavenging The inclusion of selenium, which has the effect of improving ability, anti-cancer, infertility, aging and cholesterol levels, is characteristic of lava seawater that has never been reported in deep ocean water. In addition, these minerals are in an ionized state, and the ionized minerals can be easily digested and absorbed by the human body or other animals. In addition, lava seawater is a clean groundwater resource in which E. coli, nitrate nitrogen, phosphate phosphorus, phenols, etc. are not detected, and harmful elements such as arsenic, mercury, and cadmium are not detected, or trace amounts of lead are detected, which causes obstacles to industrial application. There is no clean raw material. In particular, minerals such as magnesium and calcium contained in lava seawater are essential elements for the proliferation of Dermabiotics, and it is recommended for human consumption as an essential nutrient.

The eluted DNA has a melting temperature (Tm) among the decomposition elements, which refers to the intermediate value in the temperature change from double strand DNA to single strand DNA. After cell crushing, the eluted DNA is decomposed into nucleotides at this temperature condition with known Tm values of 70 to 105°C, and these are composed of purine and pyrimidine to stabilize between nucleotides by internal hydrogen bonding. However, the decomposed nucleotides have a strong negative charge among the components, so they have repulsion. In order to extract nucleotides having these characteristics, in order to crush cell walls and cytoplasm, the nucleotides must be maintained in a stable state even at a thermal pressure of 121° C. higher than the Tm value of 70 to 105° C.

Accordingly, the present inventors confirmed that mineral-nucleotides isolated from Derma Biotics cultured in lava seawater have significantly better skin barrier strengthening and skin damage suppression function than Derma Biotics-derived nucleotides cultured in conventional medium. Was completed.

Analyzing the results of FIG. 2, when confirming the number of Dermabiotics viable cells and nucleotides derived from Dermabiotics cultured in lava seawater according to concentrations of Example 1 and Preparation Example 1, 30 to 70 (v/ v)% Dermabiotics viable cells cultured in a medium to which lava seawater was applied, the nucleotides derived from the Dermabiotics can be seen to increase compared to cells cultured through Preparation Example 1 in which no lava seawater was applied, and 80(v /v)% Dermabiotics viable cells cultured in a medium to which lava seawater was applied, and the nucleotides derived from Dermabiotics were found to be prepared similarly to Dermabiotics cultured through Preparation Example 1.

This can be seen that the cultivation of Dermabiotics does not increase unconditionally by increasing the amount of lava seawater added, and when the salt concentration is increased by 80 (v/v)% or higher by lava seawater, the Dermabiotics culture is inhibited. Is confirmed. Accordingly, it can be seen that the proper mineral concentration in the lava seawater is an important factor in culturing Dermabiotics and forming nucleotides.

In addition, among the above results, it is preferable to use 30-70 (v/v)% of lava seawater as the culture medium for primary culture as the most optimal condition for increasing the number of Dermabiotics viable cells and increasing nucleotide formation. , Of these, it can be confirmed that the most optimal condition is to use 30(v/v)%.

<Experimental Example 2: Determination of nucleotides and minerals derived from Dermabiotics according to the second fermentation water and the time of hot pressure extraction>

In this experiment, the amount of nucleotides recovered according to the subsequent secondary culture conditions was compared after collecting Derma Biotics through centrifugation from Derma Biotics culture medium cultured using lava seawater as culture water.

To this end, the lava seawater obtained in Example 1 was centrifuged (6,000 rpm, 20 minutes) and cultured with Derma Biotics culture at a concentration of 30 (v/v)%, and only the cells were recovered and washed with sterile constant (distilled water). And this was repeated once. After that, the cells were suspended in normal constant water and lava seawater mineral concentrate (calcium 220 mg/L, magnesium 1,130 mg/L, selenium 0.013 mg/L or more), respectively, and then incubated at 37°C for 16 hours. Thereafter, hot-pressure extraction was performed at a temperature of 121° C. and a pressure of 0.15 MPa, but the hot-pressure extraction time was divided into 30 minutes and 120 minutes in order to confirm optimal heat pressure extraction conditions.

After the Dermabiotics cells were crushed by thermal pressure extraction, only the final supernatant was recovered by centrifugation (6,000 rpm, 20 minutes) after cooling the crushing solution to 4°C. The recovered supernatant was finally filtered with a nano-membrane filter of 200 nanometers or less to collect nucleotides or mineral-nucleotides derived from Dermabiotics. The nucleotide content of each condition was confirmed by using Nanodrop 2000 (Thermo, USA) to confirm the UV wavelength absorbance, and the concentration of nucleotide content derived from Dermabiotics according to the secondary fermentation water and the time of heat extraction was shown in FIG. 3.

According to the results of FIG. 3, when the nucleotide content derived from Derma Biotics secondary cultured with lava seawater mineral concentrate was confirmed, it was confirmed that the nucleotide content was increased by about 1.5 times compared to the constant secondary culture, which is the concentration of lava seawater mineral. By performing secondary fermentation through a limited number of medium, it is proved that minerals are absorbed into Derma Biotics cells and that mineral-nucleotides are formed in large quantities. This result will be explained once again through Table 1 below.

In addition, it can be seen that the largest amount of the mineral-nucleotide thus formed is extracted when the heat pressure treatment time is 120 minutes. When the lava seawater mineral concentrate is secondaryly cultured and the pressure is extracted, mineral ions inside and outside the Dermabiotics cells are reactive by heating. This increase can be said to be a result that proves that the cytoplasm and the cell wall are densely crushed inside and outside the cell, and combined with mineral-nucleotides to exhibit thermal stability. That is, lava seawater is an important factor in culturing Dermabiotics and crushing cells, and mineral concentration water is also an important factor in the time of extracting heat.

Next, the mineral content of the sample prepared by the above method was analyzed in order to confirm the concentration of minerals that are introduced from lava seawater and bound to nucleotides. Standard reagents of mineral (calcium, magnesium, selenium) in the range of about 0.1 to 1 g were titrated and diluted (nitric acid), and taken as standard solutions. The sample prepared by the above method was diluted with nitric acid. After dissolving and cooling the standard solution and sample for 1 hour in a microwave, 50 mL fill-up with tertiary distilled water is analyzed with ICPOES (PerkinElmer precisely optical emission spectrometer, Optima 5300DV) with the standard solution to show the mineral content in Table 1. Did.

Heat treatment time Second culture method Mineral content (mg/L) 30min General constant
Second culture calcium 10 magnesium 120 Selenium 0 Lava seawater minerals
Second culture of concentrated water calcium 72 magnesium 221 Selenium 0.002 120min General constant
Second culture calcium 22 magnesium 232 Selenium 0 Lava seawater minerals
Second culture of concentrated water calcium 132 magnesium 532 Selenium 0.006

As shown in Table 1, it can be seen that the amount of the mineral binding to the nucleotide in Dermobiotics is significantly increased during the secondary culture of lava seawater mineral concentrate. In addition, repeated experiments were performed to obtain supernatant containing mineral-nucleotides of calcium 50-200 mg/L, magnesium 300-800 mg/L, and selenium 0.001-0.01 mg/L during the second culture according to the method of the present invention.

<Experimental Example 3: Confirmation of dermal cytotoxicity of derma biotics-derived mineral-nucleotide complex cultured in lava seawater>

In this experimental example, dermabiotics cell wall, cytoplasm, protein and protein salt components, which affect the toxicity of skin and microbiome and fermentation of raw materials, are effectively removed with a nano-membrane filter of 200 nanometers or less. The aim was to prove that the cytotoxicity of the dermabiotics-derived mineral-nucleotide complex cultured in lava seawater was improved .

To this end, Dermabiotics-derived mineral-nucleotide obtained by primary cultivation of lava seawater 30 (v/v)% and secondary cultivation with lava seawater mineral concentrate is used as a representative sample of Example 2, and said,'Lava seawater culture Dermabio It is called'Tix derived mineral-nucleotide conjugate' or'Dermabiotics derived mineral-nucleotide conjugate cultured in lava seawater'.

In addition, the nucleotide obtained in Preparation Example 2 is referred to as'nucleotide derived from Dermabiotics in general constant culture' or'nucleotide derived from Dermabiotics cultured in normal constant'.

On the other hand, in order to impart preservation in the manufacture of the conjugate, preservatives of 2.5 (v/v)% of 1,2-hexanediol were prescribed and prepared, respectively. 1,2-hexanediol was prescribed as a control and applied as a control, and 1,2-hexanediol of the same concentration was applied to Preparation Example 3.

MTT assay is an experimental method that is frequently used for cell proliferation or toxicity by measuring the number of living cells. Living cells are water-soluble and yellow salt MTT(3-[4,5-dimethlythiazole-2-yl]-2,5 in mitochondria. The principle is that diphenyltetrazolium bromide is reduced to a water-insoluble blue formazan derivative by succinic dehydrogenase or mitochondrial dehydrogenase.

To this end, DMEM (Dulbecco's Modified Eagle) containing 10% (v/v) bovine serum by diluting fibroblasts (human fibroblasts) and keratinocytes (Human keratinocytes) at a density of 1.5×10 ⁵ cells/well in a 24 well plate Medium, Welgene, Korea) cultured at 37° C. in a 5% CO ₂ incubator for 1 day. After incubation, all of the medium was removed, replaced with DMEM medium without bovine serum, and each test sample was added for each concentration, followed by incubation for 1 day.

Thereafter, the medium was removed, and a 0.25 mg/ml MTT solution was treated to react at 37° C. for 4 hours. Thereafter, dimethyl sulfoxide (DMSO) was added to the cells from which the MTT solution was removed to dissolve MTT formazan and measured by absorbance at 570 nm.

The results for this are shown in FIGS. 4A and 4B, but cytotoxicity was not confirmed up to a concentration of 5 (v/v)% of the Derma Biotics-derived mineral-nucleotide conjugate preparation solution (supernatant) cultured in lava seawater, but 200 nanometers. Dermabiotics-derived nucleotides cultured in normal constants that were not filtered with nanometer filters below a nanometer showed cytotoxicity from the 3% (v/v) treatment group. ※ All sample concentrations in FIGS. 4 to 8 mean (v/v)%.

That is, since the sample of Preparation Example 2 does not contain cell walls, cytoplasm, protein and protein salt components, which are cell structures that cause inflammation of the skin, 3% (in both fibroblasts and keratinocytes in skin basic toxicity evaluation) v/v) It can be seen that apoptosis occurs during sample processing.

On the other hand, in the treatment group of dermabiotics-derived mineral-nucleotide conjugate cultured in lava seawater of Example 2, the inflammation-causing factors were removed through a nano-membrane filter of 200 nanometers or less to 5% (v/v). It was confirmed that skin safety was not observed even when treated with each cell of the skin. As a result of this, Dermabiotics-derived mineral-nucleotide conjugates cultured in lava seawater have improved cytotoxicity despite being produced at a high concentration of 2.0x10 ¹⁰ CFU/ml of Dermabiotics viable cells through 30% (v/v) lava seawater culture. As it is manufactured in a non-representative form, it is possible to expect maximization of skin health efficacy through implementation of more usage.

Meanwhile, in order to compare samples before and after the nano-membrane filtration process, Preparation Example 2, Preparation Example 3, and Example 2 were treated with skin fibroblasts to confirm cytotoxicity and are shown in Table 2 below. For comparison, a sample without performing a nano-membrane filter of 200 nanometers or less in the manufacturing method of Example 2 was prepared and used as a comparison group.

As a result, it can be confirmed that the preparation of a sample with little cytotoxicity is possible only by performing a nano-membrane filtration process for the production of mineral-nucleotides derived from lava seawater culture Dermabiotics according to the method of the present invention.

<Experimental Example 4: Confirmation of cell activity effect of mineral-nucleotide conjugate derived from Derma Biotics cultured in lava seawater>

To verify the mitochondrial cell membrane potential change, fibroblasts (human fibroblasts) were dispensed into 35 mm plates, stabilized for 24 hours, replaced with serum-free medium, and treated with samples (Example 2 and Preparation Example 3).

The nucleotides obtained in Preparation Example 3 are referred to as'general constant culture Dermabiotics-derived nucleotide purification' or'general constant cultured Dermabiotics-derived nucleotide purification'.

After 1 hour, after washing with a salt buffer solution (HBSS) buffer, the salt buffer solution was added to the plate as much as the cell culture solution, and then irradiated until the total irradiation amount reached 50 mJ/cm 2 of UVB. After UVB irradiation, the medium was replaced with a serum-free medium, and then treated with a sample (Example 2 and Production Example 3) at 37°C and incubated for 24 hours in a 5% CO ₂ incubator. After removing the medium, 1 μg/ml of JC-1 solution was treated and reacted for 2 hours without light in a 37° C., 5% CO ₂ incubator to remove the medium and observed under a fluorescence microscope.

Through staining with JC-1 solution, the ratio of red:green is confirmed to be 1:1 when healthy mitochondria is present, but red when stress is applied to induce mitochondrial dysfunction or cell damage or death is induced. There is no change in the green value, such as 0.5:1 :green ratio, and the red value is significantly reduced.

As shown in FIG. 5, the dermabiotics-derived mineral-nucleotide conjugate culture group cultured in lava seawater restores cells with increased damage to mitochondria due to UVB irradiation, and healthy mitochondria as a control level without UVB treatment It is confirmed to remain in the state. However, the nucleotide purification derived from Dermabiotics cultured in a general constant does not increase its value to the control level, indicating that the recovery state of mitochondria is slow.

<Experimental Example 5: Cell recovery effect through induction of mitochondrial biogenesis of dermabiotics-derived mineral-nucleotide complex cultured in lava seawater>

After fibroblasts (human fibroblast) were dispensed on a 35 mm plate and stabilized for 24 hours, the cells were replaced with serum-free medium and samples were treated. After 1 hour, after washing with a salt buffer solution (HBSS) buffer, a salt buffer solution (HBSS) was added, and then UVB 50 mJ/cm 2 was irradiated. After replacing the medium with a serum-free medium, the samples (Example 2 and Preparation Example 3) were treated and incubated for 24 hours in a 37°C, 5% CO ₂ incubator. After incubation, cells are collected with 1 ml of lysis reagent (Qiagen), and RNA is extracted using chloroform, 2-propanol, and ethanol. After adding the purified water treated with DEPC to the extracted RNA, quantitation was performed using a Qubit florometer (Invitrogen, USA) and a Qubit RNA BR Assay kit (Invitrogen, USA), and then cDNA was synthesized to perform real-time PCR. For cDNA synthesis, a high capacity RNA-to-cDNA kit (Applied Biosystems, USA) was used, and experiments were performed by the method of the kit. For real-time PCR, a kit (qPCRBIO SyGreen Blu Mic Lo-ROX, PCRBIOSYSTEMS, London, UK) was used, and experiments were performed by the method of the kit.After amplification of the gene using applied Biosystems 7500 FAST Real-Time PCR System The amplification product was quantitatively analyzed. The primers used for PCR are shown in Table 3, and were synthesized and used by Cosmogenetech (KOREA).
