Description

Technical Field

[0001] The invention relates to the technical field of denture cleaning and care products, in particular to a denture cleaner. Background Art

[0002] Dentures are auxiliary devices that replace teeth. They are generally used to replace teeth that cannot be used normally due to accidents, congenital loss or tooth aging. Cleaning dentures directly affects people's health. Common denture cleaning methods include mechanical methods, microwave radiation methods, chemical methods, etc., among which chemical methods are the most widely used. Chemical cleaners are mainly hypochlorites, peroxides, acids and enzymes according to their composition and mechanism of action.

[0003] Dentures are often made of different materials, including plastics, resins, ceramics, and metal alloys. These materials react differently to chemicals, so strong acids, bases, abrasives, and chelating agents should be avoided when cleaning dentures. Strong acids and bases are highly corrosive and may attack the surface of the denture, causing color changes or surface damage; if the denture contains metal parts, this may accelerate the corrosion of the metal and cause structural instability. Abrasives (such as abrasives) may scratch the surface of the denture during cleaning, making it rough and more susceptible to dirt and bacteria, while also affecting the appearance of the denture. Chelating agents can bind to metal ions and remove metal components from the denture, which can cause structural instability and may also change the color of the denture.

[0004] At present, some of the cleaning agents used for soaking dentures on the market are highly corrosive, and some have unsatisfactory antibacterial effects. Therefore, it is necessary to develop a denture cleaning agent with natural source, no toxic side effects, and significant antibacterial effect to replace the commercially available products. Summary of the invention

[0005] The main purpose of the present invention is to provide a denture cleaner, a method for preparing the denture cleaner and a denture cleaning method, aiming to improve the versatility of the denture cleaner.

[0006] To achieve the above object, the present invention provides a denture cleaner, wherein the preparation materials of the denture cleaner include, by weight: 3-8 parts of anionic surfactant; 1-6 parts of alkaline neutralizer; Weak alkaline neutralizer 0.5-3 parts; Acid neutralizer 0.1-1 part; 80-88 parts of solvent.

[0007] In one embodiment, the anionic surfactant includes sodium lauryl sulfate.

[0008] In one embodiment, the preparation materials of the denture cleaner further include: 0.1-0.5 parts of nonionic surfactant; The nonionic surfactant includes PEG-40 hydrogenated castor oil.

[0009] In one embodiment, the alkaline neutralizing agent includes sodium bicarbonate.

[0010] In one embodiment, the weak alkaline neutralizer includes sodium citrate.

[0011] In one embodiment, the acidic neutralizer includes one or more of citric acid, acetic acid, tartaric acid, lactic acid, and succinic acid.

[0012] In one embodiment, the preparation materials of the denture cleaner further include: 0.5 parts of preservative, wherein the preservative comprises sodium benzoate; 0.1 parts of flavor.

[0013] The present invention also provides a method for preparing a denture cleaner, which is used to prepare the denture cleaner as described in any one of the above items, and the preparation method comprises the following steps: Add the solvent, weak alkaline neutralizer and acid neutralizer according to the formula into a container and mix and stir to completely dissolve; Slowly add the alkaline neutralizer into the container according to the formula amount, and allow the alkaline neutralizer to react with the acidic neutralizer until the reaction is completed to obtain a transparent solution; Add anionic surfactant according to the formula amount into the container and stir slowly until it is completely dissolved and becomes transparent; The pre-solution of nonionic surfactant and essence is added and stirred to completely dissolve to obtain the denture cleaner.

[0014] The present invention also provides a denture cleaning method, characterized in that the cleaning method comprises the following steps: Taking a preset number of portions of the denture cleaner and diluting the denture cleaner with a solvent to obtain a washing solution; Soaking the denture in the cleaning solution for a preset time; After soaking for a preset time, take out the dentures and rinse them with clean water.

[0015] In one embodiment, in the step of taking a preset number of portions of the denture cleaner and diluting the denture cleaner with a solvent to obtain a washing solution, the ratio of the solvent to the denture cleaner is 3:1.

[0016] The technical solution of the present invention is to neutralize an acidic neutralizer with an alkaline neutralizer to generate carbon dioxide gas, thereby forming a saturated buffer solution of a salt corresponding to the weak alkaline neutralizer. After the saturated buffer solution is diluted, the salt corresponding to the weak alkaline neutralizer is hydrolyzed to generate corresponding acid ions and hydrogen ions, and the hydrogen ions continue to react with the alkaline neutralizer to generate carbon dioxide gas to form a large number of tiny bubbles in the solution. These bubbles will adhere to the surface and gaps of the dentures, and when the bubbles are formed and burst, a tiny impact force is generated, which can disturb the combination of dirt and the surface of the denture. With the formation and escape of the bubbles, microscopic mechanical disturbances and pressure changes are generated, which can be synergistic with the chemical decontamination effect of the anionic surfactant, rubbing the surface of the denture, and can more thoroughly remove organic and inorganic dirt on the surface of the denture and between the gaps of the denture, while avoiding corrosion to the denture.

[0023] In the related art, dentures are usually made of different materials, including plastics, resins, ceramics, and metal alloys, etc. These materials react differently to chemicals, so strong acids, strong alkalis, abrasives, and chelating agents need to be avoided when cleaning dentures.

[0024] To this end, the present invention provides a denture cleaner.

[0025] In the embodiment of the present invention, the preparation materials of the denture cleaner include, by weight: 3-8 parts of anionic surfactant; 1-6 parts of alkaline neutralizer; Weak alkaline neutralizer 0.5-3 parts; Acid neutralizer 0.1-1 part; 80-88 parts of solvent.

[0026] It should be noted that in the technical solution of the present invention, the acidic neutralizer is a weak acid and the alkaline neutralizer is a weak base. Carbon dioxide gas is generated by neutralizing the acidic neutralizer with the alkaline neutralizer to form a saturated buffer solution of the salt corresponding to the weak alkaline neutralizer. After the saturated buffer solution is diluted, the salt corresponding to the weak alkaline neutralizer is hydrolyzed to generate corresponding acid radical ions and hydrogen ions, and the hydrogen ions continue to react with the alkaline neutralizer to generate carbon dioxide gas to form a large number of tiny bubbles in the solution. These bubbles will adhere to the surface and gaps of the dentures, and when the bubbles are formed and burst, a tiny impact force is generated, which can disturb the combination of dirt and the surface of the dentures.

[0027] As bubbles form and escape, microscopic mechanical disturbances and pressure changes are generated, which can synergize with the chemical decontamination effect of anionic surfactants, rubbing the surface of dentures and more thoroughly removing organic and inorganic dirt on the surface of dentures and between the gaps between dentures.

[0028] At the same time, the acidic neutralizer is a weak acid and the alkaline neutralizer is a weak base, which can avoid corrosion to the dentures, extend the service life of the dentures, avoid discoloration on the surface of the dentures, and maintain the good appearance of the dentures.

[0029] The anionic surfactant is used to reduce the surface tension of the liquid, help remove dirt and grease, and enhance the cleaning effect by combining with dirt molecules to form micelles. It has the ability to reduce the surface tension of water to enhance the wettability of the solution on the surface of the denture. Specifically, the anionic surfactant can disperse hydrophobic dirt in water to form an emulsion to prevent the dirt from redepositing. In addition to improving the solution's ability to dissolve organic dirt, the anionic surfactant can also enhance the solution's foaming properties, cooperate with carbon dioxide bubbles, and improve cleaning efficiency.

[0030] The alkaline neutralizer is used to neutralize acidic substances, maintain the pH value of the detergent, help prevent corrosion and promote cleaning effects. Specifically, the alkaline neutralizer reacts with the acidic components in the solution to generate water and carbon dioxide gas, change the acid-base balance of the solution, and enhance the mildness of the detergent.

[0031] The weak alkaline neutralizer is used to further adjust the pH value, maintain the stability of the detergent, and improve the ability to remove dirt. Specifically, the weak alkaline neutralizer can react with the acidic component to form corresponding salts, increase the buffering capacity of the solution, and avoid drastic fluctuations in the pH value. At the same time, after subsequent dilution, it further dissociates to produce hydrogen ions, which continue to react with the alkaline neutralizer to generate carbon dioxide and produce bubbles.

[0032] The acidic neutralizer is used to adjust the acidity of the detergent and promote the dissolution and removal of certain dirt. Specifically, the acidic neutralizer reacts with the alkaline component to form carbon dioxide gas and salt, while improving the cleaning ability of the solution, especially for certain mineral dirt.

[0033] The solvent is used to dissolve other ingredients and provide a cleaning medium. Specifically, the polarity of the solvent helps to disperse and dissolve dirt, helping other active ingredients to work. When water is used as a solvent, it can dissolve acids, bases, salts and surfactants, promoting the uniformity and effectiveness of the detergent.

[0034] In one embodiment, the anionic surfactant includes sodium lauryl sulfate (SLS), sodium dodecyl sulfate (SDS), sodium alkylbenzene sulfonate (such as sodium linear alkylbenzene sulfonate), fatty alcohol polyoxyethylene ether sulfonate, and alkyl dimethyl ammonium chloride.

[0035] Preferably, the anionic surfactant is sodium lauryl sulfate (SLS), and the chemical structure of SLS is the sodium salt of long-chain fatty acid (dodecane) and sulfate. Its molecules have hydrophilic groups and hydrophobic groups to form an amphoteric structure. As an anionic surfactant in the formula, it can significantly reduce the surface tension of water, making it easier for the liquid to wet the surface of the denture and promote the dispersion and emulsification of dirt. When in contact with dirt, the hydrophobic part of SLS will adsorb on the dirt molecules, while the hydrophilic part remains in the water phase to form micelles. In this way, the dirt is surrounded and brought into the water, thereby achieving cleaning.

[0036] SLS can produce rich foam, which not only improves the user experience, but also enhances the mechanical action during the cleaning process, helping to remove dirt attached to the surface of dentures. SLS has a certain antibacterial effect, which can inhibit the growth of bacteria and further improve the hygiene of dentures.

[0037] Since SLS has strong decontamination ability and relatively mild properties, the present application applies it to the cleaning of dentures, which can effectively remove food residues and bacteria without causing significant damage to the denture materials.

[0038] In one embodiment, the preparation materials of the denture cleaner further include: 0.1-0.5 parts of non-ionic surfactant. Specifically, the non-ionic surfactant includes one or more of PEG-40 hydrogenated castor oil, polyvinyl alcohol (PVA), cetyltrimethylammonium chloride (CTAC), sorbitan fatty acid esters (such as Span and Tween series), polyether surfactants (such as Brij series), fatty alcohol polyoxyethylene ethers (such as C12-15 alcohol polyoxyethylene ether). Preferably, the non-ionic surfactant is PEG-40 hydrogenated castor oil.

[0039] In one embodiment, the alkaline neutralizer includes sodium bicarbonate. As an alkaline neutralizer, sodium bicarbonate (baking soda) can neutralize the acidic components in the detergent, adjust the pH value, maintain the mildness of the detergent, help remove dirt and organic matter on the dirt, and enhance the cleaning effect. At the same time, sodium bicarbonate has a slight antibacterial effect, which helps to maintain the hygiene of the denture.

[0040] In cleaners, sodium bicarbonate reacts with acidic ingredients, such as citric acid, to produce salt, water, and carbon dioxide gas: NaHCO3+HA→NaA+H2O+CO2↑ Here, HA represents an acidic component, and NaA represents a generated salt.

[0041] The carbon dioxide gas released during the neutralization reaction forms tiny bubbles that adhere to the surface of the denture and generate a tiny impact force when they burst, helping to remove dirt attached to the surface.

[0042] Sodium bicarbonate forms a buffer with other ingredients to help maintain the stability of the detergent, avoid drastic fluctuations in pH value, and ensure the effectiveness and safety of the detergent during use.

[0043] In one embodiment, the weak alkaline neutralizer includes sodium citrate. As a weak alkaline neutralizer, sodium citrate can adjust the pH value of the detergent to a suitable range, which helps to improve the mildness and stability of the detergent. Sodium citrate can react with acidic and alkaline components to form a buffer to avoid drastic pH fluctuations of the detergent during use.

[0044] Sodium citrate can react with acidic ingredients (such as citric acid) in detergents to maintain the acid-base balance of the solution:

[0045] When combined with other ingredients, sodium citrate can effectively buffer pH changes, ensuring the mildness of the cleaner during use and preventing damage to denture materials.

[0046] Sodium citrate can chelate certain deposits on denture surfaces, especially mineral deposits such as calcium and magnesium. The chelation reaction makes these metal ions more soluble, thereby reducing their deposition on the denture surface. Through chelation, these metal ions are stabilized in solution, reducing the possibility of redeposition.

[0047] In order to avoid corrosion to the denture material, in one embodiment, the acidic neutralizer includes one or more of citric acid, acetic acid, tartaric acid, lactic acid, succinic acid and malic acid. These acids are generally less corrosive and relatively mild to denture materials (such as plastics, resins and ceramics). They can effectively remove dirt, mineral deposits and pigmentation on the surface of dentures, especially scale and organic dirt, and can also effectively avoid damage. These acids are generally considered safe at low concentrations and are suitable for use in oral care products. In addition, these acids have good solubility in water and can act quickly.

[0048] In one embodiment, the preparation materials of the denture cleaner also include: 0.5 parts of preservatives and flavors.

[0049] Preferably, the preservative includes sodium benzoate. Sodium benzoate is an effective preservative that can inhibit the growth of bacteria, molds and yeasts, thereby extending the shelf life of the product and maintaining the hygiene of the denture cleaner. Sodium benzoate has an inhibitory effect on a variety of microorganisms and has a broad spectrum, making it have a good effect in terms of corrosion protection. In addition, sodium benzoate has good compatibility with other ingredients and will not interfere with the performance of the denture cleaner.

[0050] Specifically, the flavors in denture cleaners include one or more of peppermint oil, vanilla extract, lemon oil, and flavor compounds (such as ethyl acetate). The flavors can effectively mask the odor that may be produced during denture cleaning, making the use experience of the cleaner more pleasant and increasing the comfort of use.

[0051] The present invention also provides a method for preparing a denture cleaner, which is used to prepare the denture cleaner as described in any one of the above items, and the preparation method comprises the following steps: S100, adding the solvent, weak alkaline neutralizer and acidic neutralizer into a container according to the formula amount, mixing and stirring to completely dissolve; S200, slowly adding an alkaline neutralizer into a container according to the formula amount, and allowing the alkaline neutralizer to react with the acidic neutralizer until the reaction is completed to obtain a transparent solution; S300, add anionic surfactant according to the formula amount into the container and slowly stir until it is completely dissolved and becomes transparent; S400, adding the pre-solution of nonionic surfactant and essence, stirring and dissolving them completely to obtain the denture cleaner.

[0052] In step S100, the required solvent (such as water or other solvents), weak alkaline neutralizer (such as sodium citrate) and acidic neutralizer (such as citric acid) are added into a stirring container according to the formula amount. Through mixing and stirring, it is ensured that the weak alkaline and acidic components are completely dissolved to form a uniform solution, ready for the subsequent neutralization reaction.

[0053] In some embodiments, in step S100, before adding the weak alkaline neutralizer and the acidic neutralizer, the required solvent (such as water or other solvent) and the preservative according to the formula amount may be put into the container and mixed and stirred until they are completely dissolved. Then, the weak alkaline neutralizer and the acidic neutralizer are added to the solution and stirred.

[0054] In step S200, slowly add an alkaline neutralizer (such as sodium bicarbonate) into the container, ensuring that it is done under stirring, so that the alkaline neutralizer and the acidic neutralizer undergo a neutralization reaction, and the neutralization reaction produces carbon dioxide gas, and the carbon dioxide bubbles produced do not overflow the container. During this period, it can be added in multiple times, and a transparent saturated buffer solution is formed after the reaction is completed, which helps maintain the pH stability of the detergent and avoids excessive corrosiveness. The reaction equation is as follows: C6H8O7+Na3C6H5O7→Na2C6H5O7+CO2↑+H2O In step S300, an anionic surfactant such as sodium lauryl sulfate is slowly added to the mixture according to the formula amount, while continuously stirring until it is completely dissolved to form a transparent liquid. The addition of anionic surfactant enhances the decontamination ability of the detergent and can help remove dirt on the surface of the denture.

[0055] In step S400, a pre-dissolved nonionic surfactant (such as PEG-40 hydrogenated castor oil) and fragrance are added to the container and stirred continuously to ensure that they are completely dissolved. The nonionic surfactant enhances the wettability and emulsification ability of the detergent, while the fragrance enhances the use experience and increases the attractiveness of the product.

[0056] The present invention also provides a denture cleaning method, characterized in that the cleaning method comprises the following steps: S1, taking a preset number of portions of the denture cleaner, and diluting the denture cleaner with a solvent to obtain a washing solution; S2, placing the denture into the cleaning solution and soaking it for a preset time; S3. After soaking for a preset time, take out the dentures and rinse them with clean water.

[0057] In step S1, by diluting the denture cleaner with the solvent, the active ingredients in the cleaner, such as the weak alkaline neutralizer and the acidic neutralizer, can be promoted to react to produce carbon dioxide gas, thereby forming tiny bubbles. These bubbles adhere to the surface and gaps of the dentures, and as the bubbles form and burst, they generate tiny impact forces, which help disturb the combination of dirt and the denture surface and improve the cleaning efficiency. Dilution also ensures that the cleaner is evenly distributed in the washing liquid, so that the dentures can fully contact the active ingredients of the cleaner when soaking, thereby improving the overall cleaning effect.

[0058] Specifically, during the dilution process, a neutralization reaction occurs between a weak alkaline neutralizer (such as sodium citrate) and an acidic neutralizer (such as citric acid), which generates carbon dioxide gas and forms a corresponding salt.

[0059] Reaction equation:

[0060] H + +HCO3 − →CO2↑+H2O During the dilution process, the added water will dilute the original pH, allowing the reaction to continue. The generated carbon dioxide gas escapes in the form of bubbles, forming new bubbles. These bubbles provide a mechanical agitation effect, forming a microscopic impact force on the surface of the denture, which helps to loosen and remove attached dirt, and cooperates with anionic surfactants and non-ionic surfactants to remove dirt from the surface of the denture. In addition, the release of carbon dioxide causes the pH value and composition of the solution to change, which helps to increase the solubility of dirt on the surface of the denture.

[0075]

[0076] In order to verify the various properties of the denture cleaner of the present invention, the properties of the removed bovine teeth treated with the denture cleaners of the above 7 embodiments and 3 comparative examples (denture cleaning methods) were tested, and the specific steps are as follows: (1) Use a 50 ml beaker, weigh 30 ml of deionized water (or mineral water) and put it into the beaker, then take 10 ml of the denture cleaner of the present invention and inject it into the mixture; (2) Then, soak the removed teeth in the mixed solution for 12 hours; (3) After soaking, observe the cleanliness and brightness of the deboned teeth.

[0077] After the above operations (1) to (3) were completed, the cleaned dentures were observed for brightness, and the cleaned dentures were compared with the uncleaned dentures, and scored (the score was 1-5 points from low to high, and the higher the score, the better the cleaning effect), and the brightness, smoothness and cleaning effect of the dentures were evaluated. The results are shown in Table 2

[0078] See also Figure 1 , using the concentrated denture cleaning liquid of the present application, after dilution, the dirty deboned bovine teeth were immersed in it for 12 hours and then taken out. It can be obviously seen that the cleanliness is improved by at least 3 levels, and the surface is intact and smooth as before; this fully demonstrates that this product, as a steady-state liquid, will react again to produce carbon dioxide gas as the large and small molecules are converted only after being diluted with water. Through the unique unstable free characteristics of bubbles, the surfactant can fully play its role in decomposing the stain particles on the tooth surface and remove them from the tooth surface with the carbon dioxide bubbles, thereby achieving the effect of worry-free cleaning.
