Description

Technical Field

[0001] The present invention relates to the technical field of oral care products, and in particular to a tooth cleaning composition and a preparation method thereof. Background Art

[0002] There are various bacterial communities on the surface of teeth, forming bacterial biofilms, which secrete many sticky substances on their surface. Exogenous pigments from daily diets such as drinking tea, coffee, and smoking often adhere to these sticky substances, gradually turning the tooth surface yellow or black, forming stains, which not only affects the appearance, but also brings many adverse effects on psychology and life, and can cause diseases of tooth tissue and periodontal tissue. Therefore, tooth cleaning compositions play an important role in daily life. In the preparation process of tooth cleaning compositions, the degassing process directly affects the product efficacy of the tooth cleaning compositions and the user's experience. Therefore, improving the product preparation uniformity of the degassing process in the preparation of tooth cleaning compositions and improving the effective cleaning rate of tooth cleaning compositions are technical problems that need to be solved urgently.

[0003] For example, the Chinese patent authorization announcement number is: CN107625659B. This invention discloses a whitening toothpaste and a preparation method thereof, which belongs to the technical field of oral care products. The whitening toothpaste of this invention contains sodium phytate and sodium tripolyphosphate, the sum of the mass of the sodium phytate and sodium tripolyphosphate and the mass of the toothpaste is 0.5% to 10%, and the mass ratio of the sodium phytate to sodium tripolyphosphate is 1:1 to 1:7. A variety of active ingredients are added to the toothpaste of this invention, which, through the synergistic effect, maximize the effects of each active ingredient in the toothpaste, and solve the compatibility of the active ingredients and the problems brought by the paste, such as granulation, roughness, easy separation of liquid, shelling, etc., so as to achieve the purpose of cleaning and stain removal.

[0004] The prior art still has the following problems:

[0005] The prior art does not take into account the degassing process of the tooth cleaning composition during its preparation. The degree of degassing will affect the component distribution of the tooth cleaning composition. The prior art cannot adaptively select the degassing method of the tooth cleaning composition matrix according to the specific characteristics of the tooth cleaning composition matrix, which affects the cleaning effect of the tooth cleaning composition and the user experience. Summary of the invention

[0006] To this end, the present invention provides a tooth cleaning composition and a preparation method thereof, so as to overcome the problem in the prior art that the degassing method of the tooth cleaning composition matrix cannot be adaptively selected according to the specific characteristics of the tooth cleaning composition matrix.

[0007] To achieve the above object, the present invention provides a tooth cleaning composition, comprising:

[0008] The tooth cleaning composition comprises 0.1 to 15 parts of organic peroxy acid, 1 to 8 parts of phosphate, 5 to 20 parts of high-cleaning abrasive, 10 to 60 parts of moisturizing agent, 0.1 to 5 parts of sweetener, 0.01 to 5 parts of anti-caries agent, 0.1 to 5 parts of stabilizer and thickener, 1 to 10 parts of foaming agent, 0.01 to 5 parts of pH regulator, 0.5 to 1.5 parts of fragrance and balance water, with a total weight of 100 parts.

[0009] Furthermore, the organic peracid is phthalimide peroxycaproic acid, and the mass ratio of the stabilizer to the thickener in the stabilizer and thickener is 1:1.5 to 3.5.

[0010] Furthermore, in the stabilizer and thickener, the ratio of stabilizer to thickener is 1:1.8-2.5, wherein:

[0011] The stabilizer is a polyvinyl pyrrolidone polymer, and the thickener is a sodium polyacryloyl dimethyl taurate copolymer or an ammonium acryloyl dimethyl taurate / VP copolymer.

[0012] Furthermore, the pH of the tooth cleaning composition is 5.5-7.0, and the pH adjuster is one or more of trisodium phosphate, tetrasodium pyrophosphate, arginine, tromethamine, phosphoric acid and citric acid.

[0013] Furthermore, the present invention also provides a method for preparing a tooth cleaning composition, comprising:

[0014] Step S1, dispersing a stabilizer and a thickener in a moisturizer according to the raw material ratio of a tooth cleaning composition to obtain a first material;

[0015] Step S2, mixing corresponding proportions of water, phosphate, sweetener, anticaries agent and pH regulator with the first material to obtain a second material;

[0016] Step S3, mixing a high-cleaning abrasive agent and an organic peracid in corresponding proportions with the second material to obtain a third material;

[0017] Step S4, mixing the foaming agent and the aromatic agent with the third material to obtain a tooth cleaning composition base.

[0018] Furthermore, the method further comprises step S5 of degassing the tooth cleaning composition matrix, wherein:

[0019] Step S51, placing the mixed tooth cleaning composition matrix in a vacuum degassing device;

[0020] Step S52, obtaining a tooth cleaning composition matrix sample of a preset size, and applying the tooth cleaning composition matrix sample to a preset position of the simulation sheet;

[0021] Step S53, selecting a first vacuum degree for vacuum degassing the tooth cleaning composition matrix and a first air volume extracted for vacuum degassing the tooth cleaning composition matrix based on the sagging state coefficient of the tooth cleaning composition matrix sample on the simulation sheet and the viscosity of the tooth cleaning composition matrix sample;

[0022] Step S54, starting the vacuum degassing device to degas the composition matrix at the first vacuum degree for a preset first time period, wherein:

[0023] Setting the vacuum degree in the vacuum degassing equipment to the first vacuum degree and maintaining the first preset time length, obtaining the amount of extracted air, and recording the amount of air as the second amount of air;

[0024] Step S55, selecting an adjustment method for re-degassing the tooth cleaning composition matrix according to the second air volume, including:

[0025] adjusting the vacuum level for re-degassing the tooth cleaning composition matrix;

[0026] Or, the degassing time for re-degassing the tooth cleaning composition base under the current vacuum condition is adjusted.

[0027] Furthermore, in the step S52, it also includes:

[0028] Step S521, placing the simulation sheet horizontally on a workbench;

[0029] Step S522, applying the tooth cleaning composition matrix sample to the preset position and leaving it there for a preset waiting time;

[0030] Step S523, placing the simulation sheet vertically on the workbench, and calculating the sagging state coefficient of the tooth cleaning composition matrix sample based on the falling speed and adhesion ratio of the tooth cleaning composition matrix sample.

[0031] Furthermore, in the step S53, selecting a first vacuum degree for vacuum degassing the tooth cleaning composition matrix and a first amount of air extracted for vacuum degassing the tooth cleaning composition matrix comprises:

[0032] Obtaining the sagging state coefficient of the tooth cleaning composition matrix sample on the simulation sheet and the viscosity of the tooth cleaning composition matrix sample;

[0033] Selecting a first amount of air extracted for vacuum degassing the tooth cleaning composition matrix based on the sagging state coefficient and the viscosity;

[0034] A first vacuum level for vacuum degassing the tooth cleaning composition base is selected based on the viscosity.

[0035] Furthermore, in the step S55, the adjustment method for re-degassing the tooth cleaning composition matrix is ​​selected according to the second air volume, including:

[0036] comparing a ratio of the second air volume to the first air volume with a preset ratio threshold;

[0037] If the ratio is less than the ratio threshold, the selected adjustment method for re-degassing the tooth cleaning composition matrix is ​​to adjust the vacuum degree for re-degassing the tooth cleaning composition matrix;

[0038] If the ratio is greater than or equal to the ratio threshold, the selected adjustment method for re-degassing the tooth cleaning composition matrix is ​​to adjust the degassing time for re-degassing the tooth cleaning composition matrix under the current vacuum condition.

[0039] Furthermore, in the step S55, the adjustment amount of the vacuum degree of the tooth cleaning composition matrix for re-degassing is negatively correlated with the viscosity;

[0040] The increase in the degassing time for re-degassing the tooth cleaning composition matrix under the current vacuum condition is positively correlated with the ratio.

[0041] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention obtains a tooth cleaning composition matrix by stepwise mixing according to the raw material ratio of the tooth cleaning composition, degassing the tooth cleaning composition matrix, placing the mixed tooth cleaning composition matrix in a vacuum degassing device, coating a tooth cleaning composition matrix sample on a simulation sheet, selecting a first vacuum degree for vacuum degassing and a first amount of air extracted for vacuum degassing based on the sagging state coefficient and viscosity of the tooth cleaning composition matrix sample, setting the vacuum degree in the vacuum degassing device to the first vacuum degree and maintaining it for a first time, obtaining the extracted second amount of air, and selecting an adjustment method for re-degassing the tooth cleaning composition matrix according to the second air amount, thereby achieving a uniform distribution of the components in the tooth cleaning composition, allowing the tooth cleaning composition to fully contact the teeth, and adaptively selecting a method for degassing the tooth cleaning composition matrix, thereby improving the cleaning effect of the tooth cleaning composition.

[0042] In particular, the present invention selects the first amount of air extracted for vacuum degassing of the tooth cleaning composition matrix by the sagging state coefficient of the tooth cleaning composition matrix sample on the simulation sheet and the viscosity of the tooth cleaning composition matrix sample. It can be understood by those skilled in the art that the falling speed reflects the fluidity of the tooth cleaning composition matrix sample. The faster the falling speed, the more air is contained in the sample, resulting in stronger sample fluidity, and more air needs to be extracted for vacuum degassing to improve the viscosity and stability of the toothpaste. The adhesion ratio represents the degree of adhesion of the tooth cleaning composition matrix sample on the simulation sheet. A higher adhesion ratio means that the air content in the sample is less, making the sample easier to adhere to the simulation sheet. The lower the adhesion ratio, the more air content in the sample, and the more air needs to be extracted for vacuum degassing to improve the stability and adhesion of the tooth cleaning composition matrix. Furthermore, a uniform distribution of cleaning ingredients and active ingredients in the tooth cleaning composition is achieved, so that the tooth cleaning composition is fully in contact with the teeth, thereby improving the cleaning effect of the tooth cleaning composition.

[0043] In particular, the present invention selects the first vacuum degree for vacuum degassing the tooth cleaning composition matrix by the viscosity of the tooth cleaning composition matrix sample. It can be understood by those skilled in the art that when the tooth cleaning composition matrix sample has a higher viscosity, the air and moisture therein are wrapped more tightly, and degassing is relatively difficult. In this case, a higher first vacuum degree is required to overcome the binding force of the viscous substance on air and moisture, and promote the air and moisture to escape more effectively. A higher vacuum degree can increase the free path of gas molecules, making it easier for air to diffuse out of the viscous tooth cleaning composition, thereby achieving a better degassing effect. The sample has a lower viscosity, which indicates that the fluidity of air and moisture therein is relatively good, and degassing is relatively easy. In this case, a lower first vacuum degree is sufficient to meet the degassing requirements, avoiding excessive vacuum degree leading to excessive loss of some volatile components in the tooth cleaning composition, affecting the performance and quality of the tooth cleaning composition, and further achieving a uniform distribution of cleaning components and active components in the tooth cleaning composition, so that the tooth cleaning composition is in full contact with the teeth, thereby improving the cleaning effect of the tooth cleaning composition.

[0044] In particular, when the ratio is less than a ratio threshold, the present invention selects an adjustment method for re-degassing the tooth cleaning composition matrix as adjusting the vacuum degree for re-degassing the tooth cleaning composition matrix. Those skilled in the art can understand that when the ratio is less than the preset ratio threshold, it indicates that the current vacuum degree fails to effectively extract the air in the tooth cleaning composition matrix, and the second air volume is much lower than the first air volume. In the vacuum degassing process, the vacuum degree is an important parameter that determines the air extraction capacity. If the vacuum degree is insufficient, even if the degassing time is extended, the ideal degassing effect cannot be achieved. Therefore, when the second air volume is much lower than the first air volume, adjusting the vacuum degree can increase the mean free path of gas molecules, enhance the ability of air to escape from the tooth cleaning composition matrix, more effectively solve the problem of insufficient degassing, and improve the pertinence and effectiveness of degassing. Furthermore, it realizes the adaptive selection of the method for degassing the tooth cleaning composition matrix, thereby improving the cleaning effect of the tooth cleaning composition.

[0045] In particular, in the present invention, when the ratio is greater than or equal to the ratio threshold, the adjustment method for re-degassing the tooth cleaning composition matrix is ​​to adjust the degassing time for re-degassing the tooth cleaning composition matrix under the current vacuum conditions. Those skilled in the art can understand that when the ratio is greater than or equal to the ratio threshold, it indicates that under the current vacuum conditions, the actual amount of air extracted is close to the first amount of air, indicating that the current vacuum is effective for degassing the tooth cleaning composition matrix. Adjusting the degassing time can avoid excessive degassing and affect the stability and texture of the tooth cleaning composition matrix, thereby achieving adaptive selection of the method for degassing the tooth cleaning composition matrix and improving the cleaning effect of the tooth cleaning composition.

[0064] Specifically, the pH of the tooth cleaning composition is 5.5-7.0, and the pH adjuster is one or more of trisodium phosphate, tetrasodium pyrophosphate, arginine, tromethamine, phosphoric acid and citric acid.

[0065] Specifically, see Figure 1 As shown, it is a step diagram of a method for preparing a tooth cleaning composition according to an embodiment of the present invention. The present invention also provides a method for preparing a tooth cleaning composition, which is used to prepare a tooth cleaning composition, comprising:

[0066] Step S1, dispersing a stabilizer and a thickener in a moisturizer according to the raw material ratio of a tooth cleaning composition to obtain a first material;

[0069] Step S4, mixing the foaming agent and the aromatic agent with the third material to obtain a tooth cleaning composition base.

[0070] Specifically, see Figure 1 as well as Figure 2 , Figure 1 is a step diagram of a method for preparing a tooth cleaning composition according to an embodiment of the present invention, Figure 2 The step diagram of degassing the matrix of the tooth cleaning composition according to an embodiment of the present invention further includes step S5 of degassing the matrix of the tooth cleaning composition, wherein:

[0071] Step S51, placing the mixed tooth cleaning composition matrix in a vacuum degassing device;

[0072] Step S52, obtaining a tooth cleaning composition matrix sample of a preset size, and applying the tooth cleaning composition matrix sample to a preset position of the simulation sheet;

[0073] Specifically, the preset size of the tooth cleaning composition matrix sample can be set by those skilled in the art according to the component characteristics of the tooth cleaning composition. Preferably, the preset size can be a cube with a side length of 3 cm.

[0074] Specifically, the simulation piece can be a hydroxyapatite disc that is close to human tooth enamel. The hydroxyapatite disc is placed in a mixture of type III porcine gastric mucin and simulated saliva, placed in a constant temperature incubator, and cultured overnight (20 hours) at 37°C and 200rpm. The simulation piece obtains an acquired salivary protein film that simulates the tooth surface.

[0075] Specifically, the tooth cleaning composition matrix sample is coated at a preset position of the simulation sheet, preferably, at the center of the simulation sheet, to facilitate the collection of the sagging state and viscosity of the tooth cleaning composition matrix sample.

[0076] Step S53, selecting a first vacuum degree for vacuum degassing the tooth cleaning composition matrix and a first air volume extracted for vacuum degassing the tooth cleaning composition matrix based on the sagging state coefficient of the tooth cleaning composition matrix sample on the simulation sheet and the viscosity of the tooth cleaning composition matrix sample;

[0077] It is understood that the viscosity of the tooth cleaning composition base sample can be measured by a rotational viscometer, which will not be described in detail here.

[0078] Step S54, starting the vacuum degassing device to degas the composition matrix at the first vacuum degree for a preset first time period, wherein:

[0079] Setting the vacuum degree in the vacuum degassing equipment to the first vacuum degree and maintaining the first preset time length, obtaining the amount of extracted air, and recording the amount of air as the second amount of air;

[0080] Specifically, the first duration for degassing the matrix of the composition can be set by a person skilled in the art based on several historical experimental data. Preferably, the value range of the first duration can be [8,12], with the interval unit being min.

[0081] Those skilled in the art will appreciate that the amount of air extracted by the vacuum degassing equipment can be measured by a Pirani vacuum gauge, which will not be described in detail herein.

[0082] Step S55, selecting an adjustment method for re-degassing the tooth cleaning composition matrix according to the second air volume, including:

[0083] Adjustment method 1: adjusting the vacuum degree for re-degassing the tooth cleaning composition matrix;

[0084] Or, adjustment method 2: adjusting the degassing time of the tooth cleaning composition matrix for degassing again under the current vacuum condition.

[0085] Specifically, see Figure 3 As shown, it is a step diagram of obtaining the sagging state coefficient of the tooth cleaning composition matrix sample according to an embodiment of the present invention. In the step S52, it also includes:

[0086] Step S521, placing the simulation sheet horizontally on a workbench;

[0087] Step S522, applying the tooth cleaning composition matrix sample to the preset position and leaving it there for a preset waiting time;

[0088] Step S523, placing the simulation sheet vertically on the workbench, and calculating the sagging state coefficient of the tooth cleaning composition matrix sample based on the falling speed and adhesion ratio of the tooth cleaning composition matrix sample.

[0089] Specifically, the waiting time for the tooth cleaning composition matrix sample to be coated at a preset position can be set by a person skilled in the art based on the average value of several historical data. Preferably, the waiting time can be in the range of [2, 4], with the interval unit being min.

[0090] Specifically, the falling speed of the tooth cleaning composition matrix sample can be measured by aligning a laser Doppler velocimeter with a measuring point in the sample, which is a prior art and will not be described in detail herein.

[0091] Specifically, the adhesion ratio of the tooth cleaning composition matrix sample can be obtained by analyzing the morphology of the tooth cleaning composition matrix sample using image analysis technology, which will not be described in detail here.

[0092] Specifically, the sagging state coefficient of the tooth cleaning composition base sample is determined by the falling speed and the sticking ratio, wherein the sagging state coefficient is positively correlated with the falling speed and negatively correlated with the sticking ratio.

[0093] Specifically, in the step S53, selecting a first vacuum degree for vacuum degassing the tooth cleaning composition matrix and a first amount of air extracted for vacuum degassing the tooth cleaning composition matrix comprises:

[0094] Obtaining the sagging state coefficient of the tooth cleaning composition matrix sample on the simulation sheet and the viscosity of the tooth cleaning composition matrix sample;

[0095] Selecting a first amount of air extracted for vacuum degassing the tooth cleaning composition matrix based on the sagging state coefficient and the viscosity;

[0096] A first vacuum level for vacuum degassing the tooth cleaning composition base is selected based on the viscosity.

[0097] Specifically, the value range of the first vacuum degree can be [-0.056, -0.04], and the interval unit is MPa. Those skilled in the art can understand that the larger the absolute value of the vacuum degree, the higher the vacuum degree. The value of the first vacuum degree can be selected according to the viscosity of the tooth cleaning composition matrix. The higher the viscosity, the larger the absolute value of the selected first vacuum degree.

[0098] Specifically, the present invention selects the first amount of air extracted for vacuum degassing of the tooth cleaning composition matrix by the sagging state coefficient of the tooth cleaning composition matrix sample on the simulation sheet and the viscosity of the tooth cleaning composition matrix sample. It can be understood by those skilled in the art that the falling speed reflects the fluidity of the tooth cleaning composition matrix sample. The faster the falling speed, the more air is contained in the sample, resulting in stronger sample fluidity, and more air needs to be extracted for vacuum degassing to improve the viscosity and stability of the toothpaste. The adhesion ratio represents the degree of adhesion of the tooth cleaning composition matrix sample on the simulation sheet. A higher adhesion ratio means that the air content in the sample is less, making the sample easier to adhere to the simulation sheet. The lower the adhesion ratio, the more air content in the sample, and the more air needs to be extracted for vacuum degassing to improve the stability and adhesion of the tooth cleaning composition matrix. Furthermore, a uniform distribution of cleaning ingredients and active ingredients in the tooth cleaning composition is achieved, so that the tooth cleaning composition is fully in contact with the teeth, thereby improving the cleaning effect of the tooth cleaning composition.

[0099] Specifically, the present invention selects the first vacuum degree for vacuum degassing the tooth cleaning composition matrix by the viscosity of the tooth cleaning composition matrix sample. It can be understood by those skilled in the art that when the tooth cleaning composition matrix sample has a higher viscosity, the air and moisture therein are wrapped more tightly, and degassing is relatively difficult. In this case, a higher first vacuum degree is required to overcome the binding force of the viscous substance on air and moisture, so as to promote the air and moisture to escape more effectively. A higher vacuum degree can increase the free path of gas molecules, making it easier for air to diffuse out of the viscous tooth cleaning composition, thereby achieving a better degassing effect. The sample has a lower viscosity, indicating that the fluidity of air and moisture therein is relatively good, and degassing is relatively easy. In this case, a lower first vacuum degree is sufficient to meet the degassing requirements, avoiding excessive vacuum degree leading to excessive loss of some volatile components in the tooth cleaning composition, affecting the performance and quality of the tooth cleaning composition, and further achieving a uniform distribution of cleaning components and active components in the tooth cleaning composition, so that the tooth cleaning composition is in full contact with the teeth, thereby improving the cleaning effect of the tooth cleaning composition.

[0100] Specifically, see Figure 4 As shown, it is a logic flow chart of selecting an adjustment method for re-degassing the tooth cleaning composition matrix according to an embodiment of the present invention. In the step S55, the adjustment method for re-degassing the tooth cleaning composition matrix is ​​selected according to the second air volume, including:

[0101] comparing a ratio of the second air volume to the first air volume with a preset ratio threshold;

[0102] If the ratio is less than the ratio threshold, the selected adjustment method for re-degassing the tooth cleaning composition matrix is ​​to adjust the vacuum degree for re-degassing the tooth cleaning composition matrix;

[0103] If the ratio is greater than or equal to the ratio threshold, the selected adjustment method for re-degassing the tooth cleaning composition matrix is ​​to adjust the degassing time for re-degassing the tooth cleaning composition matrix under the current vacuum condition.

[0104] Specifically, the threshold value of the ratio of the second air volume to the first air volume may be set by a person skilled in the art based on a fitting value of historical data of several experiments. Preferably, the value range of the threshold value of the ratio may be [0.5, 0.7].

[0105] Specifically, in the present invention, when the ratio is less than the ratio threshold, the adjustment method selected for re-degassing the tooth cleaning composition matrix is ​​to adjust the vacuum degree for re-degassing the tooth cleaning composition matrix. Those skilled in the art can understand that when the ratio is less than the preset ratio threshold, it indicates that the current vacuum degree fails to effectively extract the air in the tooth cleaning composition matrix, and the second air volume is much lower than the first air volume. In the vacuum degassing process, the vacuum degree is an important parameter that determines the air extraction capacity. If the vacuum degree is insufficient, even if the degassing time is extended, the ideal degassing effect cannot be achieved. Therefore, when the second air volume is much lower than the first air volume, adjusting the vacuum degree can increase the mean free path of gas molecules, enhance the ability of air to escape from the tooth cleaning composition matrix, more effectively solve the problem of insufficient degassing, improve the pertinence and effectiveness of degassing, and further, realize the adaptive selection of the method for degassing the tooth cleaning composition matrix, thereby improving the cleaning effect of the tooth cleaning composition.

[0106] Specifically, when the ratio is greater than or equal to the ratio threshold, the present invention selects an adjustment method for re-degassing the tooth cleaning composition matrix as adjusting the degassing time for re-degassing the tooth cleaning composition matrix under the current vacuum conditions. Those skilled in the art can understand that when the ratio is greater than or equal to the ratio threshold, it indicates that under the current vacuum conditions, the actual amount of air extracted is close to the first amount of air, indicating that the current vacuum is effective for degassing the tooth cleaning composition matrix. Adjusting the degassing time can avoid excessive degassing and affect the stability and texture of the tooth cleaning composition matrix, thereby achieving adaptive selection of the method for degassing the tooth cleaning composition matrix and improving the cleaning effect of the tooth cleaning composition.

[0107] Specifically, in the step S55, the adjustment amount of the vacuum degree for re-degassing the tooth cleaning composition matrix is ​​negatively correlated with the viscosity;

[0108] In a specific embodiment, the adjustment amount of the vacuum degree for re-degassing can be determined by multiplying the viscosity coefficient by the current vacuum degree, wherein the viscosity coefficient can be calculated by substituting the average viscosity of the tooth cleaning composition matrix that passed the degassing test in several historical tests and the average vacuum degree into a polynomial.

[0109] The increase in the degassing time for re-degassing the tooth cleaning composition matrix under the current vacuum condition is positively correlated with the ratio.

[0110] In a specific embodiment, the increase in the degassing time for re-degassing can be determined by multiplying the air volume coefficient by the current degassing time, wherein the vacuum coefficient can be calculated based on the difference between the amount of air extracted from the tooth cleaning composition matrix that has passed the degassing test in several historical tests and the current amount of air extracted.

[0115] Embodiment 2:

[0116] A hydroxyapatite disc similar to human tooth enamel was selected as a simulation disc and placed in II The mixture of type I porcine gastric mucin and simulated saliva was placed in a constant temperature incubator and cultured overnight (20 hours) at 37°C and 200rpm to obtain an acquired salivary protein film on the simulated tooth surface. The hydroxyapatite sheet was placed in a black tea solution and dyed for 30 minutes to simulate exogenous tooth stains. The dyed hydroxyapatite sheet was fixed on a sampling sheet and installed in a brush grinder. Water and the tooth cleaning composition were stirred and mixed at a dilution ratio of 1:1.6 and added to the slurry cup of the brush grinder. The toothbrush load pressure was adjusted to 150g, and the toothbrush was brushed 1000 times at a speed of 80rpm to simulate the human brushing process. After the brushing test, the chromaticity value of the hydroxyapatite sheet before and after dyeing was measured using a spectrophotometer.
