Description

[Technical Field]

[0001] The present invention relates to a cosmetic product and a method for producing the cosmetic product. [Background technology]

[0002] As an example of a cosmetic containing ingredients derived from hot springs, Patent Document 1 discloses a cosmetic characterized by having as its main ingredients moor hot spring water and white crane reishi mushroom, white crane reishi mushroom extract, or white crane reishi mushroom extract powder.

[0003] Furthermore, as described in Non-Patent Document 1, the importance of natural moisturizing factors (NMFs) contained in the skin is recognized in improving the skin's moisturizing ability. Part of the composition of these NMFs contains specific electrolytes such as sodium ions. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-239146 [Non-patent literature]

[0005] [Non-Patent Document 1] Toshiyuki Takemura, "Effectiveness of Moisturizing Preparations - Moisturizing Mechanism of the Stratum Corneum", Pharmacia, Vol. 28, No. 1, 1992, 61-65 Summary of the Invention [Problem to be solved by the invention]

[0006] The technology disclosed in Patent Document 1 promotes the improvement of the skin's moisturizing ability by adding and mixing specific moisturizers such as Hakutsuru Reishi, Hakutsuru Reishi extract, or Hakutsuru Reishi extract powder to hot spring water.

[0007] However, although Patent Document 1 mentions that the moisturizer contains sodium ions, it does not specifically mention NMF. Furthermore, it does not mention the effect that specific electrolytes contained in hot spring water have on skin moisturizing, or the osmotic pressure of hot spring water.

[0008] Non-Patent Document 1 only explains the skin's moisturizing mechanism, and does not explain about cosmetics containing hot spring water as an ingredient.

[0009] Therefore, the inventors of the present invention have attempted to solve the problem of improving moisturizing power by a means different from that of the prior art. Specifically, they have focused on the fact that the electrolytes contained in hot spring water constitute part of the skin's natural moisturizing factors (NMF), that they are similar to the electrolytes contained in human body fluids, and that hot spring water has hypotonic properties.

[0010] The present invention has been made in consideration of the above points, and aims to provide a cosmetic product and a method for producing the cosmetic product that improves moisturizing power by focusing on the electrolytes contained in hot spring water and the osmotic pressure of hot spring water. [Means for solving the problem]

[0011] A water component containing hot spring water containing sodium ions, potassium ions, magnesium ions, and calcium ions, which is hypotonic and has a salt concentration of 0.1% or more and less than 0.9%; Moisturizer and Oil components and An emulsifier, a skin beauty ingredient containing at least ceramide; The present invention is characterized by comprising:

[0012] The cosmetic of the present invention can provide a cosmetic with excellent moisturizing power. This is because the cations (sodium ions, potassium ions, magnesium ions, calcium ions) contained in the hot spring water of the present invention are ionic components that constitute part of the NMF, and the NMF helps to retain moisture in the stratum corneum. Furthermore, the water components containing the hot spring water are hypotonic, and when the salt concentration is 0.1% or more, a predetermined amount of sodium ions is contained. When the salt concentration is less than 0.9%, the salt concentration is lower than that of body fluids, and the skin easily absorbs moisture due to osmotic pressure, thereby improving moisturizing power.

[0013] Preferred examples of the cosmetic of the present invention are: The hot spring water is characterized by containing 78% to 92% sodium ions when the total concentration of sodium ions, potassium ions, magnesium ions, and calcium ions is taken as 100%.

[0014] A preferred example of the cosmetic of the present invention contains cations that constitute human body fluids, and the proportion of these cations is similar to the proportion of cations in human body fluids, particularly extracellular fluid, making it possible to reduce the load when the cosmetic is applied and penetrates into capillaries.

[0015] Preferred examples of the cosmetic of the present invention are: It is characterized in that the water component further contains metasilicic acid.

[0016] According to a preferred example of the cosmetic of the present invention, It contains metasilicic acid, which promotes skin metabolism and regulates moisturizing ceramides, further improving moisturizing power.

[0017] Preferred examples of the cosmetic of the present invention are: The water component is ultra-hard water.

[0018] According to a preferred example of the cosmetic of the present invention, It is rich in calcium, which promotes metabolism and activates moisturizing ingredients in skin cells, and magnesium, which helps restore skin barrier function, thereby improving moisturizing power.

[0019] Preferred examples of the cosmetic of the present invention are: The pH of the water component is 7.1 to 7.4.

[0020] According to a preferred example of the cosmetic of the present invention, The pH of the water component contained in the cosmetic is 7.1 to 7.4, which is close to the normal pH range of blood, 7.35 to 7.45, so the load on the blood vessels when it penetrates can be reduced.

[0021] Preferred examples of the cosmetic of the present invention are: The oxidation-reduction potential of the water component is -80 mV to +270 mV.

[0022] According to a preferred example of the cosmetic of the present invention, The water component has a pH range of 7.1 to 7.4 and an oxidation-reduction potential of -80 mV to +270 mV, which prevents oxidation of the skin and improves moisturizing power compared to using only purified water, which has an oxidation-reduction potential of approximately 500 mV, which is used in general cosmetics.

[0023] Preferred examples of the cosmetic of the present invention are: It is characterized in that a chelating agent is added to the water component.

[0024] According to a preferred example of the cosmetic of the present invention, discoloration and precipitation caused by metal ions can be suppressed, thereby preventing deterioration in product quality and improving storage stability such as appearance.

[0025] The method for producing a cosmetic of the present invention comprises the steps of: The method for producing the above cosmetic product, The method comprises a pre-process of producing a basic lotion that is a base material for cosmetics, and a post-process of processing the basic lotion to produce cosmetics, The preceding process is a hot spring water filling step of filling a sterilized container with sterile hot spring water through a pipe without exposing the container to outside air, and filling the container with only the hot spring water as the water component; a chelating agent addition step of adding and stirring a chelating agent within 5 minutes after filling the hot spring water; and an auxiliary moisturizing agent addition step of adding an auxiliary moisturizing agent to the hot spring water as needed and stirring the water. The post-processing step includes: a basic lotion heating step of heating the basic lotion produced in the previous step to a temperature suitable for mixing with the main moisturizer and emulsifying with the oil component, and then stopping the heating; a main moisturizing agent addition step of adding and mixing a main moisturizing agent to the basic lotion; an emulsifier addition step of adding the emulsifier to the basic lotion and stirring the mixture to prepare an emulsifier-mixed water; an oil component heating step of heating the oil component in a container separate from the emulsifier-mixed water to a temperature suitable for mixing the oil component with the ceramide and emulsifying the oil component with the emulsifier-mixed water, and then stopping the heating; a ceramide addition step of adding the ceramide to the oil component and mixing them; an emulsion preparation step of mixing and stirring the emulsifier-mixed water and the oil component to prepare an emulsion; The present invention is characterized by comprising:

[0030] Hereinafter, embodiments of the cosmetic product and the method for manufacturing the cosmetic product of the present invention will be described in detail with reference to the accompanying drawings. Note that a basic lotion is first produced, and then the cosmetic product according to this embodiment is manufactured based on that basic lotion. Therefore, the basic lotion will be described first.

[0031] [Basic lotion] The hot spring water contained in the water component, which is the main component of the skincare lotion, contains sodium ions, potassium ions, magnesium ions, and calcium ions. For example, it is preferable to use hot spring water from near No. 604, Matsunoki, Nagashima-cho, Kuwana City, Mie Prefecture, with the spring quality shown in Figure 1. In the skincare lotion of this embodiment, "hot spring water" refers to hot spring water from near No. 604, Matsunoki, Nagashima-cho, Kuwana City, Mie Prefecture, or a mixture of the hot spring water and purified water. However, other hot spring waters can also be used as long as their components are similar to those of the water component described above. While other raw materials constituting the skincare lotion may also contain water, this water is not considered a water component.

[0032] As shown in Figure 1, hot spring water contains sodium ions (Na + ) is 2240mg, 97.43mval, 77.94mval%, potassium ion (K + ) is 23.0mg, 0.59mval, 0.47mval%, magnesium ion (Mg 2+ ) is 50.1mg, 4.12mval, 3.30mval%, calcium ion (Ca 2+ ) is contained in the hot spring water at 444.1 mg, 22.16 mval, and 17.73 mval%. "mval" is a unit of electrolyte concentration, and is the number of equivalents of electrolyte dissolved in 1 kg of hot spring water. "mval%" is the ratio of the mval values ​​of cations and anions to the sum of their respective values.

[0033] Furthermore, when the total concentration of sodium ions, potassium ions, magnesium ions, and calcium ions is taken as 100%, the hot spring water preferably contains sodium ions at a ratio of 78.4% to 91.6%. As for other ions, it is preferable that the hot spring water contains potassium ions at a ratio of 0.5 to 3.2%, magnesium ions at a ratio of 1.9 to 3.3%, and calcium ions at a ratio of 3.2 to 17.8%.

[0034] The reason for the above ratio is as follows: Body fluids are divided into extracellular fluid and intracellular fluid, and extracellular fluid in particular fills the spaces between cells and communicates with the blood through the capillary walls. Therefore, it is considered preferable that the electrolyte ratio of hot spring water, or the water components as a whole, be similar to the electrolyte ratio of the extracellular fluid, which will be explained below. This is because it is possible to reduce the load when penetrating into the capillaries.

[0035] Figure 2(A) shows the electrolytes (cations) in extracellular fluid (Haruo Sugi et al., Human Functional Physiology, 2nd Revised Edition, Nanzando, 1991). Here, "mEq / L" is a unit of electrolyte concentration, and is the number of equivalents of an electrolyte dissolved in 1 L of solution. If the total concentration of sodium ions, potassium ions, magnesium ions, and calcium ions is set at 100%, and their ratios are calculated, it is found that sodium ions, which play an important role in regulating the osmotic pressure of body fluids, account for the highest proportion at 91.6% (Figure 2(C)). Therefore, it is preferable that hot spring water used in skin care lotions also have a higher proportion of sodium ions than the other cations mentioned above.

[0036] Figure 2(B) shows an excerpt from Figure 1 for the sodium ions, potassium ions, magnesium ions, and calcium ions contained in hot spring water. As mentioned above, "mval" is the equivalent number of electrolytes dissolved in 1 kg of hot spring water. Although the unit notation is different, the density of hot spring water is approximately 1 g / cm 3 Therefore, in this case, "mval" and the above-mentioned "mEq / L" have substantially the same meaning and can be compared. Therefore, when the total concentration of these sodium ions, potassium ions, magnesium ions, and calcium ions is taken as 100%, the ratio is calculated and it is found that the hot spring water of this embodiment also has a higher proportion of sodium ions than the other cations mentioned above, at 78.4% (FIG. 2(C)). From the above, the lower limit of sodium ions was set to 78.4% and the upper limit to 91.6%. The same calculations were made for the other ions. For convenience, the above ratios will be expressed as "%".

[0037] The hot spring water used should be hypotonic. Here, "hypotonic" refers to hot spring water in which the amount of dissolved substances (excluding gaseous substances) per 1 kg is less than 8000 mg / kg, according to the Guidelines for Mineral Spring Analysis. More preferably, the amount is 7121 mg / kg or more but less than 8000 mg / kg. The water components used should be such that the amount of dissolved substances (excluding gaseous substances) per 1 kg of water components is 1780 mg / kg or more but less than 8000 mg / kg.

[0038] The salinity of hot spring water is preferably less than 0.9%, which is the salinity of body fluids. More preferably, it is 0.6% or more and less than 0.9% (the lower limit of the salinity is the salinity shown in FIG. 5 rounded to one decimal place; the same applies below). The salinity of the water component is preferably 0.1% or more and less than 0.9%. A salinity of 0.1% or more results in the inclusion of a predetermined amount of sodium ions, and a salinity of less than 0.9% is lower than the salinity of body fluids, allowing the skin to more easily absorb moisture due to the difference in osmotic pressure. Furthermore, it is preferable that the water component contains 24.36 mval to 97.43 mval of sodium ions, 0.15 mval to 0.59 mval of potassium ions, 1.03 mval to 4.12 mval of magnesium ions, and 5.54 mval to 22.16 mval of calcium ions per kg of water component.

[0039] Preferably, the hot spring water further contains metasilicic acid. This is because metasilicic acid promotes skin metabolism and regulates moisturizing ceramides, thereby improving moisturizing power. The amount of metasilicic acid contained in the hot spring water is 71.7 mg, which is preferably 50 mg or more, as stipulated in Article 2 of the Hot Springs Act. In this embodiment, the water component preferably contains 17.9 mg to 71.7 mg.

[0040] The hot spring water is preferably ultra-hard water. According to the Ministry of Health, Labor and Welfare, "ultra-hard water" refers to water in which the amount of calcium ions and magnesium ions converted into the corresponding amount of calcium carbonate (CaCO3) is 180 mg / L or more. The hardness of this hot spring water is 1315.7 mg / L. In this embodiment, the water preferably contains 328.9 mg / L to 1315.7 mg / L of water components. This results in an abundance of calcium and magnesium, which can improve moisturizing power.

[0041] The pH of hot spring water is 7.3 to 7.4. In this embodiment, the pH of the water component is preferably 7.1 to 7.4. The normal pH range of blood is 7.35 to 7.45, and a pH closer to that of blood can reduce the load on the capillaries when the water penetrates the capillaries.

[0042] Furthermore, the redox potential of hot spring water is -80 mV at a pH of 7.4. The redox potential of the water component in this embodiment is preferably -80 mV to +270 mV at a pH of 7.1 to 7.4. This is because, compared to purified water used in general skin care products, which has a redox potential of approximately 500 mV, the use of water components with reducing power can prevent skin oxidation and improve moisturizing power.

[0043] The above-mentioned values ​​for the amount of dissolved substances (excluding gaseous substances), mVal value of cations, salinity, amount of metasilicic acid, hardness, pH, and redox potential are based on the values ​​for Components 1 to 3 shown in Figures 1 and 5. As will be described later, among Components 1 to 4 shown in Figure 5, 1 had the highest moisturizing effect, followed by 2 and 3, and 4 had the lowest effect (Figure 6). For this reason, it can be said that the values ​​for Components 1 to 3 are preferred, those for Components 1 and 2 are more preferred, and those for Component 1 are most preferred.

[0044] A chelating agent is preferably added to the skincare lotion according to this embodiment. Common chelating agents, such as ethylenediaminetetraacetic acid (EDTA), etidronic acid, edetic acid, citric acid, and their sodium salts, may be used alone or in combination. In this embodiment, citric acid and sodium citrate are used. This combination provides a chelating effect that inhibits metal ion-derived precipitation while adjusting the overall pH of the skincare lotion. Furthermore, depending on the blending ratio, if the skincare lotion is to be applied with less irritation, it can be adjusted to neutral or slightly acidic to approach the skin's pH. Alternatively, if the load on the capillaries is to be reduced or if the hardened keratin on the skin surface is to be softened, it can be adjusted to a weak base, as described above. Therefore, if the load on the capillaries is to be reduced, the pH is adjusted to 7.1 to 7.4. If the skin is to be less irritated, the pH is adjusted to 6.0 to 7.0, preferably 6.0 to 6.8.

[0045] It is preferable to add an auxiliary moisturizing agent to the skincare lotion according to this embodiment. Common auxiliary moisturizing agents such as 1,2-hexanediol, 1,3-butylene glycol, dipropylene glycol, glycerin, and urea may be used, either singly or in combination. In this embodiment, glycerin and urea are used. This combination has been used in numerous skincare lotions and has a proven track record, and is expected to ensure quality and safety, improve usability, and further enhance moisturizing power.

[0046] Although not particularly limited, in this embodiment, the water component consisting of hot spring water and purified water is 94.99 to 100% by mass (however, the hot spring water in the water component is 25 to 100% by mass when the water component is 100% by mass), and the chelating agents citric acid 0 to 0.01% by mass, sodium citrate 0 to 1% by mass, and auxiliary humectants glycerin 0 to 3% by mass, and urea 0 to 1% by mass are contained. This is because if the hot spring water in the water component is less than 25% by mass, the moisturizing power may not be fully exerted. Furthermore, when using hot spring water containing iron ions as in this embodiment, it is recommended to add a chelating agent because the iron ions may oxidize and turn brown, causing hot spring sediment. Furthermore, to improve the feel when used, it is recommended to add an auxiliary humectant.

[0047] Next, a method for producing a basic skin lotion will be described in detail with reference to the accompanying drawings. The method for producing a basic skin lotion described here is a pre-step in the method for producing a skin lotion described below.

[0048] [Basic lotion manufacturing method] [First embodiment] The method for producing the skin lotion according to this embodiment will be described below. As shown in Fig. 3, the method includes a hot spring water filling step S101, a chelating agent adding step S102, and an auxiliary moisturizing agent adding step S103.

[0049] The hot spring water filling process S101 is a process of filling a sterilized container with sterile hot spring water. Here, "sterile" and "sterile state" refer to a general bacterial count of 0 CFU / mL and a negative coliform count, as shown in Figure 7. This was measured using the testing method specified in the "Notice on Partial Revision of Hot Spring Usage Standards" (No. 075001002, dated October 1, 2007). In the manufacturing method of this embodiment, only hot spring water from near 604 Matsunoki, Nagashima-cho, Kuwana City, Mie Prefecture is used as the "water component," and purified water is not used. Note that other ingredients that make up the skincare lotion may contain water, but this water is not considered a water component. The hot spring water is pumped from 1,500 meters underground using a submersible pump. At this time, the hot spring water temperature is 49°C (air temperature: 12°C). This hot spring water is filled into a sterilized container through a pipe without being exposed to outside air. "Keeping the water out of contact with the outside air" means that the hot spring water is not exposed to the air from the submersible pump to the outlet of the piping. This maintains a hygienic condition and prevents oxidation of the hot spring water. Valves are installed in the piping, and the hot spring water is filled into the container by adjusting the valves.

[0050] Because the hot spring water of this embodiment contains natural gases such as methane (gas:water ratio 1:11, gas flow rate 20 L / min), when the hot spring water is filled into the container through the pipe, the gases contained in the hot spring water and the steam generated by the hot spring water are released into the container. Therefore, the hot spring water accumulating at the bottom of the container is isolated from the atmosphere by the gases, and the hot spring water is substantially isolated from the outside air while filling the container. Furthermore, even after filling the container with hot spring water, gases are released for a while. Therefore, by promptly performing the chelating agent addition step S102 and the auxiliary humectant addition step S103, or by placing an appropriate lid on the container, the hot spring water can be kept substantially isolated from the outside air. Furthermore, the natural gas in the hot spring water of this embodiment has a gas specific gravity of 0.63. However, even if hot spring water containing carbon dioxide, which has a gas specific gravity of 1 or higher, is used, the liquid surface is covered with carbon dioxide, and thus the hot spring water is substantially isolated from the outside air while filling the container. However, to prevent oxidation, the atmosphere inside the container can be purged with an inert gas.

[0051] The chelating agent addition step S102 is a step of adding and stirring a chelating agent within a predetermined time period. The chelating agent is preferably added and stirred within 5 minutes after filling the hot spring water in the hot spring water filling step S101. If the time exceeds 5 minutes, the chelating agent may oxidize and turn brown, potentially producing hot spring precipitates derived from iron ions. More preferably, the chelating agent is added and stirred within 1 minute after filling the hot spring water. A general stirrer can be used for this stirring. Alternatively, the sealed container may be vibrated (the same applies to the auxiliary moisturizing agent addition step and other embodiments described below).

[0052] The auxiliary moisturizing agent addition step S103 is a step of adding an auxiliary moisturizing agent to the hot spring water and stirring. To increase the dissolution efficiency of the auxiliary moisturizing agent, it is preferable to add the auxiliary moisturizing agent and stir it before the hot spring water temperature reaches 45° C. The chelating agent addition step S102 and the auxiliary moisturizing agent addition step S103 may be performed simultaneously, or their orders may be reversed.

[0053] According to this embodiment, the chelating agent and auxiliary moisturizing agent can be mixed in stages while checking their dissolution, and the hot spring water filling step S101, the chelating agent addition step S102, and the auxiliary moisturizing agent addition step S103 can be carried out simultaneously. [Second embodiment] The method for producing a basic lotion according to this embodiment will be described. As shown in Figure 4, the method includes an additive preparation step S201 and a hot spring water filling step S101. Here, the meanings of terms such as "sterile," "sterile state," "water component," and "not exposed to the outside air" are the same as those explained in the first embodiment.

[0054] The additive preparation step S201 involves adding a chelating agent and auxiliary humectant to a sterilized container and stirring as needed. The chelating agent and auxiliary humectant can also be added simultaneously. For example, in this embodiment, citric acid and sodium citrate are used as chelating agents, and glycerin and urea are used as auxiliary humectants. To improve stirring efficiency, the order in which the ingredients are added can be changed depending on the state of the ingredients, such as by first adding liquid glycerin to the container and then adding the other ingredients while stirring. Alternatively, the ingredients may be mixed as a whole in anticipation of dissolution in the subsequent hot spring water filling step S101. The hot spring water filling step S101 is the same step as that described in the first embodiment, and therefore will not be described here.

[0055] According to this embodiment, the hot spring water reacts with the chelating agent immediately after being filled, so the condition in the chelating agent addition step S102 of the first embodiment that the chelating agent be added "within 5 minutes after being filled with hot spring water" can be omitted. Also, in the auxiliary moisturizing agent addition step S103 of the first embodiment, the hot spring water can be stirred without worrying about a drop in temperature.

[0056] [Cosmetics] Next, a cosmetic product of this embodiment using the above-described basic skin lotion will be described. The cosmetic product of this embodiment contains the basic skin lotion, a moisturizer, an oil component, an emulsifier, a preservative, a fragrance, and a skin-beautifying component. Details of the basic skin lotion are as described above.

[0057] The moisturizer comprises an auxiliary moisturizer contained in the basic lotion and a primary moisturizer that is further added to the basic lotion. The auxiliary moisturizer has already been described. The auxiliary moisturizer is not an essential component and can be omitted. In this embodiment, for example, trehalose, BG (1,3-butylene glycol), propanediol, etc. are used as the primary moisturizer.

[0058] The oil component used is one that can prevent dryness and seal in moisture. In this embodiment, for example, jojoba oil, white olive oil, argan oil, etc. are used.

[0059] In this embodiment, for example, a (sodium acrylate / sodium acryloyldimethyltaurate) copolymer or the like is used as the emulsifier.

[0060] In this embodiment, for example, phenoxyethanol or the like is used as the preservative.

[0061] In this embodiment, for example, yuzu extract oil or the like is used as the flavoring, and it is preferable to use natural oil.

[0062] The skin beauty ingredient can be selected depending on the desired function, such as moisturizing or wrinkle improvement. In this embodiment, for example, collagen water, plant-derived extract blends (Roman chamomile flower extract, calendula officinalis flower extract, cornflower flower extract, chamomile flower extract, St. John's wort flower / stem / leaf extract, Tilia cordata flower extract, etc.), niacinamide, hyaluronic acid (sodium hyaluronate, hyaluronic acid, hydrolyzed sodium hyaluronate, hydrolyzed hyaluronic acid, potassium hyaluronate, sodium acetylated hyaluronate, sodium hyaluronate crosspolymer, hydroxypropyltrimonium hyaluronate, etc.), placenta, vitamins (ascorbic acid, niacinamide, panthenol, biotin, folic acid, tocopherol, retinol palmitate, pyridoxine HCl, etc.), ceramides (ceramide AP, ceramide NP, ceramide EOP, etc.), etc. may be used.

[0063] Examples of the blending ratios (mass %) of these basic lotions, main moisturizers, oil components, emulsifiers, preservatives, fragrances, and skin-beautifying ingredients are shown in the table in Figure 8. Here, basic lotions are the most abundant, at 68.51%. The other ingredients are as shown in the table, but the blending ratios of the various ingredients are not limited to these and can be changed as appropriate.

[0064] Furthermore, in this embodiment, the cosmetic has a pH of 6.7 and an oxidation-reduction potential of -25 mV after production, and has reducing power, which can prevent oxidation of the skin and improve moisturizing power.

[0065] [Cosmetic manufacturing method] The cosmetic manufacturing method of this embodiment comprises a pre-process and a post-process. The pre-process is the same as the above-described method for manufacturing a base lotion. In the first embodiment of the cosmetic manufacturing method, the pre-process corresponds to the first embodiment of the method for manufacturing a base lotion. Furthermore, in the second embodiment of the cosmetic manufacturing method, the pre-process corresponds to the second embodiment of the method for manufacturing a base lotion. The post-process is common to both the first and second embodiments. Therefore, the post-process will be described here.

[0066] As shown in FIG. 9, the post-processing steps in the cosmetic manufacturing method of this embodiment include a basic lotion heating step S301, a primary moisturizer adding step S302, an emulsifier adding step S303, an oil component heating step S304, a ceramide adding step S305, an emulsion preparation step S306, and a post-material adding step S307.

[0067] In the basic lotion heating step S301, the basic lotion produced in the previous step is heated to a temperature suitable for mixing with the main moisturizer and emulsifying with the oil component, and then the heating is stopped. The heating temperature is, for example, 75°C to 85°C, and in this embodiment it is set to 80°C. The heating is preferably stopped before the subsequent emulsifier addition step S303 or emulsion preparation step S306. Here, "mixing" not only means mixing, but also includes the meaning of dissolving (the same applies to the ceramide addition step S305).

[0068] The primary moisturizer addition step S302 involves adding the primary moisturizer to the base lotion and mixing it. The base lotion may be stirred to promote mixing. This primary moisturizer addition step S302 may be performed before or simultaneously with the base lotion heating step S301.

[0069] In the emulsifier addition step S303, an emulsifier is added to the heated basic skin lotion while stirring, to prepare an emulsifier-mixed water.

[0070] In the oil component heating step S304, the oil component is heated in a separate container from the emulsifier-mixed water until it reaches a temperature suitable for mixing with the ceramide and emulsifying with the emulsifier-mixed water, and then the heating is stopped. For example, a hot water bath is used as the heating method. The heating temperature is, for example, 80°C to 90°C, and in this embodiment, it is set to 85°C. The heating is preferably stopped before the subsequent emulsion preparation step S306. This oil component heating step S304 is preferably performed in parallel with the above-mentioned basic lotion heating step S301.

[0071] In the ceramide addition step S305, ceramide, one of the skin beautifying ingredients, is added to the oil component, and the mixture is stirred and mixed as necessary. This ceramide addition step S305 may be performed before or simultaneously with the oil component heating step S304.

[0072] In the emulsion preparation step S306, the emulsifier-mixed water and the oil component are mixed and stirred to prepare an emulsion. Here, the emulsifier-mixed water is stirred while the oil component to which the ceramide has been added is added to the emulsifier-mixed water to prepare the emulsion. It is also possible to add the emulsifier-mixed water to the oil component while stirring the oil component.

[0073] In the post-material addition step S307, when the temperature of the emulsion prepared in the emulsion preparation step S306 approaches room temperature, for example, below 40°C, preservatives, fragrances, and skin-beautifying ingredients other than ceramide are added to the emulsion. Here too, stirring is performed as necessary. [Example]

[0074] [Adjustment and evaluation of water components in basic lotion] As shown in Figure 5, components 1 to 3 were prepared by varying the ratio of hot spring water to purified water. Component 4 was made of purified water only. (Component 2 was made of hot spring water:purified water = 1:1, and component 3 was made of hot spring water:purified water = 1:3.) The hot spring water used was from near 604 Matsunoki, Nagashima-cho, Kuwana City, Mie Prefecture, and has the spring quality shown in Figure 1. The analytical data in Figure 1 was measured by an analytical institution (Japan Water Treatment Co., Ltd.) in accordance with the Ministry of the Environment's Mineral Spring Analysis Guidelines (measurement equipment and measurement error, etc., follow the analytical institution's instructions). The purified water used was Furukawa Chemical Co., Ltd., product number 02-101.

[0075] [Dissolved matter (excluding gaseous matter), mval value of cations, salinity, metasilicic acid, hardness] The mval values ​​of dissolved substances (excluding gaseous substances) and cations in Figure 5 (Na + , K. + , Mg 2+ , Ca 2+ ), salinity, amount of metasilicic acid, and hardness values ​​are based on the analysis data of the hot spring water shown in Figure 1, or calculated from that analysis data. The salinity was calculated by converting the amount of sodium ions into the amount of salt. The hardness was calculated from the amounts of magnesium ions and calcium ions.

[0076] [pH, redox potential] The pH in FIG. 5 was measured at a temperature of 25° C. using a handheld pH meter (manufactured by Sato Keiryoki Seisakusho Co., Ltd., model number: SK-629pHII) (II represents the Roman numeral "2"). The oxidation-reduction potential in FIG. 5 was measured at a temperature of 25° C. using a digital ORP meter (manufactured by Mother Tools Co., Ltd., model number: YK-23RP).

[0077] [Moisturizing evaluation of basic lotion] Next, using components 1 to 4 of the water component, basic skin lotions Examples 1 to 4 and Comparative Examples 1 and 2 were prepared with the formulations shown in FIG. Using the prepared skin lotion, four subjects (three women and one man) were evaluated for moisturizing. The test was conducted at 25°C by applying 1.0 mL of the skin lotion to the entire face of each subject using a spray bottle, and the moisture content of the area below the cheekbones was measured three minutes later using a moisture checker (manufactured by Scalar Corporation, model number: MY-808S). The evaluation results are shown in Figure 6.

[0078] The moisturizing evaluation results of Example 1 and Comparative Example 1, and Example 2 and Comparative Example 2 in Figure 6 show that when the water component is hot spring water, the moisturizing power is higher than when the water component is purified water, regardless of individual differences. Furthermore, when Example 1 and Comparative Example 2 are compared, the results show that hot spring water alone has approximately the same moisturizing power as purified water containing auxiliary moisturizers, etc. Furthermore, the results of Examples 2 to 4, in which the blend ratio of purified water and hot spring water was changed, also show that the moisturizing power tends to increase as the ratio of hot spring water increases.

[0079] [Bacteria testing of hot spring water and basic lotion] The basic lotion obtained by the manufacturing method of the first embodiment, in comparison with the hot spring water and Example 2 in Figure 6, was collected in a 1000 mL container, sealed, and stored, and was measured by an analytical institution (Mie Prefecture Environmental Conservation Corporation, a general incorporated association) using the testing method specified in the "Partial Revision of Hot Spring Usage Standards (Notice)" No. 075001002 of the Environmental Protection Agency of Japan, dated October 1, 2007. The evaluation results are shown in Figure 7.

[0080] The results of the bacterial test in Figure 7 show that the hot spring water is in a sterile state. Furthermore, the skin care lotion obtained by the manufacturing method of the first embodiment had a general bacterial count of 15 CFU / mL and a negative coliform count two days after manufacturing, and a general bacterial count of 43 CFU / mL and a negative coliform count three months after manufacturing, demonstrating that a hygienic condition has been maintained. Incidentally, the standard values ​​for item testing for drinking mineral springs (Notice No. 075001002, October 1, 2007, "Regarding Partial Revision of Hot Spring Usage Standards") are a general bacterial count of 100 CFU / mL or less and no detectable coliform count.

[0081] [Evaluation of moisturizing properties of cosmetics] Cosmetics Examples 5 and 6 were prepared with the formulations shown in Figure 8 (Figure 10). Figure 11 lists the product names and manufacturers of the main moisturizer, oil component, emulsifier, preservative, fragrance, and skin care component. The skin care lotion used was a skin care lotion that used only hot spring water as the water component (Example 2 in Figure 6). The moisturizing evaluation of the cosmetic of this embodiment will be described with reference to Figure 10. The evaluation method involved spreading 2 grams of the cosmetic over the entire face of the same four subjects (three women and one man) as used in measuring the basic lotion, and measuring the moisture content under the cheekbones three and ten minutes later using a moisture checker (manufactured by Scalar Corporation, model number: MY-808S).

[0082] As a result, the moisturizing evaluation score was similar to that of the basic lotion in Example 2, which had the best score among the basic lotions. Furthermore, even when re-measured after 10 minutes, the moisturizing evaluation score remained almost unchanged, and the initial moisturizing state was maintained.

[0083] As explained above, the cosmetic of this embodiment contains hot spring water containing sodium ions, potassium ions, magnesium ions, and calcium ions in its water component, and when the water component is hypotonic and the above-mentioned electrolytes, particularly sodium ions, are present at a predetermined concentration or higher, moisturizing power can be improved. This is thought to be due to the osmotic pressure of the hot spring water, as well as the fact that the sodium ions, potassium ions, magnesium ions, and calcium ions contained in the hot spring water are ionic components that make up part of the NMF. Furthermore, these cations are the same ions as those contained in human body fluids. It is presumed that applying a cosmetic containing these cations to the skin regulates the electrolyte concentration in the capillaries under the skin due to osmotic pressure, improving vascular condition, thereby distributing essential nutrients and moisture to the skin and improving moisturizing power.

[0084] In addition to the aforementioned "NMF," the skin's natural moisture is also maintained by factors such as "sebum" and "intercellular lipids." Therefore, the cosmetic product of the present invention can maintain good skin condition by supplementing "NMF" and moisture with a basic lotion and main moisturizer as described above, and by supplementing "sebum," which prevents moisture evaporation from the stratum corneum, with oil components, and "intercellular lipids" with "ceramide," a component that accounts for more than half of the intercellular lipids. Furthermore, ceramide not only plays a role in "tightly holding water" between cells, but also acts to connect cells together and prevent the penetration of external stimuli. Therefore, it is believed that the initial moisturizing state was maintained.

[0085] Furthermore, according to the cosmetic production method of this embodiment, the temperature of the hot spring water is utilized in the pre-process, eliminating the need for temperature control. Furthermore, adding a chelating agent to suppress hot spring precipitation eliminates the need for processes such as filtration and purification. Furthermore, in the case of skin lotions, a hygienic state can be maintained for a long period of time without the addition of preservatives. This reduces the cost of cosmetic production. Furthermore, the skin lotion maintains a low redox potential even after several days have passed since production. For example, the value of a product opened one month ago was 31 mV, while the value of an unopened product left unopened for four months was 45 mV. These factors are believed to be responsible for maintaining a hygienic state and a low redox potential, as a result of filling the container with hot spring water from the piping without exposing it to outside air in the pre-process of the cosmetic production method of this embodiment, and for the gases released from the hot spring water, preventing the hot spring water from coming into contact with outside air even during filling.

[0086] Furthermore, since the basic lotion is produced in the first process and the cosmetic product is produced in the second process, part of the manufacturing process can be shared between the basic lotion and the cosmetic product, which is economical in terms of production equipment and manufacturing management. Of course, the basic lotion manufactured in the first process can be shipped as a lotion as is.

[0087] The above-described cosmetics and methods for producing cosmetics are merely examples of the present invention, and the configurations thereof can be modified as appropriate within the scope of the invention.
