Description

  The present invention relates to cosmetics, water treatment agents, and deodorizers, and particularly to cosmetics, water treatment agents, and deodorizers that use deep sea water.

  In recent years, attention has been focused on deep ocean water having a depth of 200 to 300 m or less, where sunlight does not reach. In deep ocean waters, photosynthesis by phytoplankton is not performed, mineral nutrients are accumulated by the ability of bacteria to decompose, and nutrients such as nitrates and phosphates essential for plant growth are abundant. In addition, since sunlight does not reach, the water temperature is low and stable throughout the year. In particular, the deep sea water of the Sado Strait is called “Japan Sea Proper Water” and is characterized by an extremely cool water temperature of around 1 ° C. compared to the deep sea water on the Pacific side. In addition, deep seawater is not mixed with surface seawater of different specific gravity, there are few harmful artificial pollutants from the land and the atmosphere, and the number of bacteria and organic matter is very low, maintaining cleanliness. Yes. In addition, about 95% of the seawater existing on the earth is deep seawater, and since it is naturally regenerated by ocean current circulation, it is attracting attention as a future resource.

  As described above, the deep ocean water has cleanliness, low-temperature stability, and eutrophication, but is also known to have ripening properties and mineral properties. Deep-sea water has been matured over many years under high pressure of 20 atm or more, and when used in cosmetics, it penetrates the skin well. When used in foods, it has a mild taste. It is said that it is related to. In addition, seawater contains a balance of essential trace elements and minerals necessary for living organisms, such as calcium, magnesium, iron, zinc, and sodium.

  Due to these superior characteristics, deep ocean water has already begun to be used in a variety of fields, including fisheries, food, beverages, health, beauty, and medical care, causing problems such as environmental degradation and resource depletion. In addition, the utilization of deep ocean water is expected to expand more and more in the future with health-consciousness.

For example, as for the use of deep sea water for bathing agents, inorganic salts and water-soluble polymers added with seawater and hinokitiol (Patent Document 1), and coral sand and seawater (Patent Document 2). ) Is known, but a small amount of seawater is added to a solid or powdery basic component as a conventional bathing agent, and the characteristics of the deep ocean water are sufficiently utilized. There wasn't.

It is suitably used as a spray-type deodorant or spray-type disinfectant used for products.

  As the water used in the present invention, any of fresh water such as ground water, purified water, mineral water, sea water such as ocean surface water and ocean deep water can be used. In addition, since deep sea water is excellent in cleanliness, eutrophication, ripening property, and mineral characteristics, it is more preferably used as seawater used in the present invention.

  As chitosan used in the present invention, chitin contained in crustaceans and shellfish such as crabs and shrimps is extracted and purified by deacetylation treatment. Generally, those having a degree of deacetylation of 60% or more are referred to as chitosan, but those having a degree of deacetylation of less than 60% can also be used. In general, chitosan contains about 20% chitin that has not been deacetylated. As the chitosan used in the present invention, a relatively low molecular weight water-soluble chitosan having a molecular weight of 10,000 or less is preferably used. In addition, even high molecular weight chitosan having a molecular weight exceeding 10,000 can be dissolved in water by adding weakly acidic substances such as ascorbic acid, lactic acid, humic acid, acetic acid, and citric acid. Molecular weight chitosan can also be used.

  Chitosan is the only animal-derived dietary fiber, is harmless to the living body, is highly safe, and is effective as a natural preservative. In addition, it has a moisturizing and water retaining effect, and has a moisturizing effect 1.5 to 2 times that of hyaluronic acid, which has the effect of retaining water in the cell gap and maintaining the smoothness and suppleness of the skin. In addition, it has antibacterial and antibacterial effects, and it has natural antiseptic properties. It has antibacterial and antibacterial properties against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Legionella, etc. There is an effect to protect. In addition, it has a cohesive property that hardens foreign matter in water and is also used for purification of polluted water. In addition, the amino group is very active in terms of molecular structure, and therefore has an action of adsorbing by chemically contacting, adhering and combining with noxious substances such as precious metals, radioactive substances and chlorine. In addition, heavy metals such as copper, zinc, cadmium, mercury and uranium are adsorbed well, and magnesium and calcium are not adsorbed. In addition, it contains ingredients that have been confirmed to have bactericidal action in medicine, has high biocompatibility, and has analgesic and hemostatic effects, suppressing inflammation and accelerating the healing of wounds such as dermatitis, eczema, acne, and burns effective.

  L-lactic acid, L-ascorbic acid, and / or humic acid are selectively added to the cosmetics, water treatment agent or deodorant of the present invention. By adding these, water becomes weakly acidic and the dissolution of chitosan in water becomes easy. In addition, when L-lactic acid, L-ascorbic acid, and / or humic acid are added before adding chitosan, the dissolution of chitosan becomes easier. Further, L-lactic acid has antiseptic and antibacterial effects, L-ascorbic acid has a skin whitening effect, that is, has an effect of suppressing melanin pigments and preventing freckles, and humic acid has a water purification effect. is there. L-lactic acid, L-ascorbic acid, and humic acid are selectively added, but preferably one or more are added. When only one kind is added, it is preferable to add L-lactic acid in view of acid stability.

  Next, a method for preparing the cosmetics, water treatment agent or deodorant of the present invention will be described.

  First, water is heated, and when it boils, it is stopped and cooled to room temperature. This water heating is performed for sterilization and may be omitted. Next, this water is filtered to remove insoluble matters. Then, L-lactic acid, L-ascorbic acid, and / or humic acid is selectively added and stirred to dissolve in seawater, and then chitosan is added and stirred to dissolve. Then, after stirring and leaving for a while, it is filtered to remove insoluble matters, followed by heating at about 70 ° C. for several hours and filtering. This heating and filtration can be omitted. Thereafter, it is further filtered and cooled to room temperature. The cosmetics, water treatment agent or deodorizing agent of the present invention can be obtained by the above method. In addition, you may use this cosmetics, a water treatment agent, or a deodorizing agent as it is, or you may add components, such as oil, surfactant, and a fragrance | flavor as needed, and you may use it as a product.

  When the cosmetics of the present invention obtained as described above is used as a bath agent, water is purified by adding an appropriate amount to water such as a bathtub. That is, by adding the bathing agent of the present invention, residual chlorine in tap water is adsorbed, and malodor such as chlorine gas is removed by removing chlorine. Further, magnesium, calcium, etc. are not adsorbed, but heavy metals such as copper, zinc, cadmium, mercury, uranium are well adsorbed, and foreign substances in water are aggregated. In addition, the bathing agent of the present invention has an antibacterial activity against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Legionella, and the like due to its natural antiseptic performance, and also has antifungal and bactericidal action.

  On the cosmetic side, it has a skin whitening effect that suppresses melanin pigments and prevents freckles, and is 1.5 to 2 times that of hyaluronic acid, which maintains water smoothness and suppleness by retaining water in the cell gaps. Has moisturizing and water-retaining effects. In addition, due to its natural antiseptic performance, it has antibacterial activity against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Legionella, etc., and has the effect of protecting the skin by controlling the bacteria with a conditioning effect. Furthermore, the component contained in the bath agent of the present invention works on the dermis, and the elasticity of the skin increases, preventing wrinkles and sagging. It has high biocompatibility and has analgesic and hemostatic effects, and has the effect of suppressing inflammation and accelerating the healing of wounds such as dermatitis, eczema, acne and burns. In addition, since the bath agent of this invention is prepared only from the natural component, it is completely harmless and safe for a human body.

  The effects as described above can also be obtained when used in lotions other than bath additives, bath additives, hair sprays, deodorants, soaps, shampoos, rinses, toothpastes and the like. Also, spraying the hair after perm can remove the smell of the perm solution and increase the elasticity and gloss of the hair. In addition, even if it is blended in the permanent liquid from the beginning instead of spraying, the smell of the permanent liquid can be erased and the elasticity and gloss of the hair can be increased.

  Further, when the water treatment agent of the present invention obtained as described above is used as a pool bactericidal agent or a pool water purifying agent, it is sterilized in water by adding an appropriate amount to the pool water. The chitosan contained in the water treatment agent of the present invention provides a bactericidal effect equivalent to that of sodium hypochlorite as a conventional pool bactericidal agent. Moreover, since chitosan is harmless to the human body, it is safer than using sodium hypochlorite. Furthermore, since it has the effect | action which purify | cleans water as mentioned above, and the effect in a cosmetics, the disinfectant for pools and the water purifier for pools which were not excellent conventionally can be provided.

  Moreover, when using the deodorizing agent of this invention obtained as mentioned above, if a spray etc. are carried out to the location which wants to deodorize, it will deodorize effectively with the chitosan contained in the deodorizing agent of this invention.

  In addition, this invention is not limited to the said Example, A various deformation | transformation implementation is possible.

  The following specific examples further illustrate the present invention. In this example, an example of preparation of a pool disinfectant and a pool water purifier is shown.

  Deep-sea water collected from the 300m depth off Hatano-cho, Sado was heated to boiling, and then left to cool to room temperature.

  Next, this raw water is passed through a filter (Advantech, 4A) to remove insoluble matters, 0.70 g of L-lactic acid and 3.67 g of L-ascorbic acid are added per 1 liter of raw water, and 1 minute using a magnetic mixer. This was dissolved by stirring. Next, 2.00 g of chitosan (manufactured by Wako Pure Chemical Industries, deacetylation rate (after drying) 80.0 mol% or more, molecular weight of about 1000) is added, and a mag mixer is used for 2-3 minutes so that chitosan does not become lumpy. Stir gently and dissolve. Subsequently, the mixture was vigorously stirred for 30 to 60 minutes using a mag mixer, and then allowed to stand for 1 hour. Then, this was passed through a filter, heated at 70 ° C. for 2 hours, then passed again through the filter and cooled to room temperature. Then, the filter was passed again through a filter to obtain a yellow transparent and liquid pool disinfectant and pool water purifier. This is filled into a container to obtain a product. In addition, when the container is stored without filling the container with the pool disinfectant or the pool water purifier, it may be passed through the filter again immediately before shipping and then filled into the container to obtain a product.

  When used for purposes other than pool disinfectant and pool water purifier, the above raw water, pool disinfectant and pool water purifier may be mixed at an appropriate ratio to dilute the concentration of chitosan, etc. Good. When mixing the above raw water, pool disinfectant, and pool water purifier, mix the raw water, pool disinfectant, and pool water purifier thoroughly using ultrasonic waves, and after passing through a filter, fill the container. That's fine.

  Using the pool disinfectant and pool water purifier of Example 1 above, a test for removing residual chlorine in tap water was conducted. In this test, we looked at whether iodine contained in iodine tincture instead of chlorine could be removed.

  When 0.2 ml of iodine tincture was added to 10 ml of tap water, it was colored yellow. When 0.5 ml of the pool bactericidal agent and the water purification agent for pool of Example 1 were added thereto, it became transparent instantly. By this test, it was confirmed that the disinfectant for pools and the water purifier for pools of the present invention have a chlorine removing effect.

  Using the pool disinfectant and pool water purifier of Example 1 above, a chlorine removal test was conducted.

  1 ml of water having a chlorine concentration of 0.91 mg / l was charged with 1 ml of the pool bactericidal agent and pool water purifier, and the fluctuation of the chlorine concentration was measured (chlorine concentration measuring instrument: RC-24P residual, manufactured by Toa DKK Corporation. Chlorine meter). In addition, the fluctuation | variation of chlorine concentration was measured also about what added the disinfectant for pools and the water purifier for pools only with 1 l of water with a chlorine concentration of 1.08 mg / l. The numerical values of the measurement results are shown in Tables 1 and 2, and the graph is shown in FIG.

  A significant decrease in chlorine concentration was observed in the case where the pool disinfectant and the water purification agent for pool of Example 1 were added, but no decrease in the chlorine concentration was observed in the case where the disinfectant was not added. From this result, it was confirmed that the pool disinfectant and the pool water purifier of the present invention have a chlorine removing effect.

  Using the pool disinfectant and pool water purifier of Example 1 above, a pollution removal test was conducted. In this test, the purification effect of water was observed by an aeration test in which a filter was put into polluted water, air was applied, and the dirt was sucked onto the filter.

  The disinfectant for pool 1 and 1 ppm of water purifier for pool 1 were put in 200 ml of polluted water, and aerated by passing air with an air pump (air pump for general ornamental fish tank) through a filter immersed in the polluted water. When the pool disinfectant and the pool water purifier of Example 1 were added, the dirt was attracted to the filter, and the water became completely transparent by aeration for 10 minutes. When the pool disinfectant and pool water purifier were not added, there was no change and the water remained cloudy. By this test, it was confirmed that the disinfectant for pools and the water purifier for pools of the present invention have an action of purifying polluted water.
