Description

Technical Field

[0001] The invention belongs to the technical field of toothpaste preparation, and in particular relates to a mild stain-removing and whitening toothpaste containing diatomaceous earth and coconut shell carbon and a preparation method thereof. Background Art

[0002] Stain-removing and whitening toothpaste is an oral care product specifically designed to help remove surface stains and brighten teeth. It typically contains mild abrasives, active whitening ingredients such as hydrogen peroxide or calcium carbonate, and other ingredients to help clean and protect teeth. Using this toothpaste can help reduce discoloration caused by diet, smoking, or other lifestyle habits, restoring teeth's natural whiteness. Many stain-removing and whitening toothpastes also contain fluoride to strengthen teeth and prevent cavities, ensuring you maintain a healthy oral health while pursuing a beautiful smile.

[0003] Existing toothpastes mostly rely on chemical abrasives (such as calcium carbonate, silica) and synthetic surfactants, which have the following defects: (1) The contradiction between stain removal and mildness. Traditional abrasive particles are coarse and hard, which can easily damage tooth enamel; chemical stain removers (such as hydrogen peroxide) may cause gum sensitivity;

[0004] (2) Insufficient adsorption capacity: Ordinary activated carbon has limited adsorption capacity, making it difficult to deeply remove dental plaque and exogenous pigments;

[0005] (3) Environmental protection and safety issues: synthetic ingredients have poor biodegradability, and long-term use may destroy the balance of oral microecology. Summary of the Invention

[0006] The present invention aims to provide a mild stain-removing and whitening toothpaste containing diatomaceous earth and coconut shell carbon, aiming to resolve the contradiction between stain removal and mildness. Traditional abrasive particles are coarse and hard, which can easily damage tooth enamel; chemical stain removers may cause gum sensitivity.

[0007] The present invention is achieved by providing a mild stain-removing and whitening toothpaste containing diatomaceous earth and coconut shell carbon, comprising:

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0026] A gentle stain-removing, whitening toothpaste with diatomaceous earth and coconut shell charcoal, including:

[0027] Changbai Mountain diatomaceous earth friction agent 9-30%, sorbitol 32-38%, sodium lauroyl silicate 2-4%, polyethylene glycol 400 2-3%, coconut shell carbon 0.5-2%, polyvinyl pyrrolidone 0.6-1%, honeysuckle extract 0.5-0.8%, Panax notoginseng extract 0.5-0.7%, xanthan gum 0.5-0.8%, 1,2-hexanediol 0.1-0.2%, flavor 0.5-0.8% and water.

[0028] Sorbitol, also known as sorbitol, is a humectant that can effectively maintain the moisture and fluidity of toothpaste. Polyethylene glycol 400 is also a humectant. While increasing the moisturizing properties, it can also work with the main ingredients to achieve the effect of stain removal and whitening.

[0029] like Figure 1 As shown, Changbai Mountain diatomaceous earth is the main abrasive in toothpaste. It uses carefully selected food-grade raw materials, with a whiteness of up to 95%, an amorphous silicon dioxide content of about 95%, a porosity of over 85%, and low hardness. It can absorb stains, quickly wrap bacteria and odor factors through porous materials, and achieve the effects of stain removal, whitening, and removing bad breath. Figure 2As shown, coconut shell carbon is another main component of the abrasive in toothpaste. It uses food-grade raw materials and is refined and purified in coconut shells. The iodine value is as high as 1500-3000. It can effectively absorb pigments, bacteria and odor factors. It is soft and does not damage tooth enamel.

[0030] Polyvinylpyrrolidone is also an important stain-removing ingredient in this toothpaste. It removes tooth stains and pigments by combining with the complex pigment phenol functional groups. It gently removes tooth stains in a non-friction, non-oxidative manner and forms a tooth protective film around the teeth to block the invasion of pigment factors; xanthan gum is a commonly used thickener in toothpaste; sodium lauroyl silicate is a foaming ingredient, which mainly uses its emulsifying effect to evenly combine oil-soluble and water-soluble raw materials to form a stable system.

[0031] Honeysuckle extract and Panax notoginseng extract are Chinese herbal medicine extracts, which are mainly compounded with abrasives as ingredients for sterilization and deodorization, thereby improving the deodorization effect of toothpaste.

[0032] The use of food flavors, such as mint flavors, will allow toothpaste users to experience a cool and refreshing taste.

[0033] Example 1:

[0034] This embodiment discloses a mild stain-removing, whitening, and bad breath-eliminating toothpaste containing diatomaceous earth and coconut shell carbon, which comprises the following components in the following weight ratios: 26% Changbai Mountain diatomaceous earth abrasive, 35% sorbitol, 3% sodium lauroyl silicate, 3% polyethylene glycol 400, 1.2% coconut shell carbon, 0.7% polyvinyl pyrrolidone, 0.6% honeysuckle flower extract, 0.7% Panax notoginseng extract, 0.7% xanthan gum, 0.1% 1,2-hexanediol, and 29% deionized water.

[0035] The preparation method is:

[0036] Step 1: Add oil-soluble raw materials A (sorbitol, polyethylene glycol, 1,2-hexanediol and xanthan gum) to a premixed oil pot and stir at 60°C until transparent; add water-soluble raw materials B (sodium lauroyl silicate and polyvinyl pyrrolidone) to a premixed water pot and dissolve at 50°C; mix and sieve powdered raw materials C (Changbai Mountain diatomaceous earth, coconut shell carbon, Panax notoginseng extract and honeysuckle flower extract) in advance for use;

[0037] Step 2: The paste making machine vacuum-inhales raw materials A and B, stirs them at room temperature for 30 minutes, and prepares raw material D. Then, raw material C is inhaled and homogenized and stirred for 30 minutes under vacuum conditions to prepare a fine toothpaste paste. The essence is then inhaled and stirred for 15 minutes under vacuum conditions to prepare a mild stain-removing and whitening paste.

[0038] Step three: take out the prepared paste and use a filling machine to fill the paste to obtain a finished toothpaste.

[0039] Example 2:

[0040] This embodiment discloses a mild stain-removing, whitening, and bad breath-removing toothpaste containing diatomaceous earth and coconut shell carbon, which comprises the following components in weight ratio: 24% Changbai Mountain diatomaceous earth abrasive, 36% sorbitol, 3% sodium lauroyl silicate, 2.5% polyethylene glycol 400, 1.5% coconut shell carbon; 0.6% polyvinyl pyrrolidone, 0.6% honeysuckle flower extract, 0.7% Panax notoginseng extract, 0.7% xanthan gum, 0.1% 1,2-hexanediol, and 31% deionized water.

[0041] The preparation method thereof is the same as that of Example 1 except that the weight ratio is different.

[0045] Example 4:

[0046] This embodiment discloses a mild stain-removing, whitening, and bad breath-eliminating toothpaste containing diatomaceous earth and coconut shell carbon, and a preparation method thereof. The toothpaste comprises the following components in weight ratio: 22% Changbai Mountain diatomaceous earth abrasive, 35.5% sorbitol, 2.5% sodium lauroyl silicate, 2.3% polyethylene glycol-400, 1% coconut shell carbon, 0.7% polyvinyl pyrrolidone, 0.6% honeysuckle flower extract, 0.65% Panax notoginseng extract, 0.7% xanthan gum, 0.1% 1,2-hexanediol, and 33.95% deionized water.

[0047] The preparation method thereof is the same as that of Example 1 except that the weight ratio is different, and other process operations are the same.

[0048] Example 5:

[0049] This embodiment discloses a mild stain-removing, whitening, and bad breath-eliminating toothpaste containing diatomaceous earth and coconut shell carbon. The toothpaste comprises the following components in the following weight ratios: 26% Changbai Mountain diatomaceous earth abrasive, 35% sorbitol, 2.5% sodium lauroyl silicate, 3% polyethylene glycol-400, 2% coconut shell carbon, 0.7% polyvinyl pyrrolidone, 0.6% honeysuckle flower extract, 0.65% Panax notoginseng extract, 0.7% xanthan gum, 0.1% 1,2-hexanediol, and 28.75% deionized water.

[0050] The preparation method thereof is the same as that of Example 1 except that the weight ratio is different, and other process operations are the same.

[0051] The mild stain-removing, whitening and deodorizing toothpastes containing diatomaceous earth and coconut shell carbon in Examples 1 to 5 were tested for deodorizing. The test process and results are as follows:

[0052] Step 1: Select two typical oral odor-producing bacteria, namely Streptococcus mutans and Porphyromonas gingivalis;

[0053] Step 2: Use a micropipette to drop 10 μL of bacterial solution with a concentration of 5.0×10 6 CFU / mL~5.0×10 7 Place a bacterial suspension of 500 CFU / mL on a dry sterilized carrier and dry it at (36±1)℃ or air-dry it at room temperature for later use.

[0054] Step 3: Weigh the test sample at 5 g / tablet and place it in a sterile dish. Use sterile tweezers to take the infected carrier and immerse it completely in the test sample. Start the time immediately.

[0055] Step 4: After 24 hours of exposure, take the infected carrier and add it to a test tube containing 5.0 mL of PBS. Mix it with an electric mixer for 20 seconds until the test bacteria are fully washed off. Pipette 1.0 mL of the sample solution and determine the number of surviving bacteria according to the live bacteria culture counting method. Incubate at (36±1)°C for the specified time (anaerobic culture of Streptococcus mutans for 48 hours, anaerobic culture of Porphyromonas gingivalis for 4 days) and then count the live bacteria.

[0056] Step 5: Replace the test sample with PBS and follow the above steps to serve as the control sample. Repeat the experiment three times and calculate the average value.

[0057] Step 6: Calculate the antibacterial rate of the toothpaste formula according to the formula: antibacterial rate (%) = (average number of viable bacteria in the control group - average number of viable bacteria in the test group) / average number of viable bacteria in the control group × 100%.

[0058] Step seven, make judgment based on the evaluation criteria: if the inhibition rate is ≥50-90%, the product has an antibacterial effect; if the inhibition rate is ≥90%, the product has a strong antibacterial effect.

[0059] Assume that the experimental groups of Examples 1 to 5 are Experimental Group 1, Experimental Group 2, Experimental Group 3, Experimental Group 4 and Experimental Group 5 respectively, and the specific experimental results are shown in Tables 1 and 2:

[0060] Table 1 Antibacterial rate (Streptococcus mutans) of toothpaste samples from Examples 1 to 5

[0061]

[0062] Table 2 Antibacterial rate (Porphyromonas gingivalis) of toothpaste samples from Examples 1 to 5

[0063]

[0064] The statistical results show that the antibacterial rates of the toothpastes of Examples 1 to 5 are all as high as 99.97% after 24 hours of use. Therefore, it is believed that the mild stain-removing, whitening and bad breath-eliminating toothpaste containing diatomaceous earth and coconut shell carbon of the present invention has significant effects of removing bad breath and refreshing breath.

[0065] Whitening tests were conducted on the mild stain removal, whitening and bad breath removal toothpastes containing diatomaceous earth and coconut shell carbon in Examples 1 to 5. The test process and results are as follows:

[0066] Step 1: Cow tooth staining: rinse the cow teeth with pure water for 10 seconds, add enough tea and coffee to the beaker, then add 300ml of pure water and boil until the tea and coffee are completely boiled and the color becomes darker. After filtering the tea leaves, put the cow teeth in to soak, refrigerate. After 7 days, the tea stains are completely colored, rinse with water for 1 to 2 minutes and set aside.

[0067] Step 2: Rinse the 6 separated bovine teeth in pure water and brush them with a toothbrush for 30 seconds. Then group them evenly according to their location, shape and size.

[0068] Step 3: Set up a sample group T and a negative control group Y. Brush twice a day. Each time the sample group brushes, squeeze 2.0g of sample per tooth and brush each tooth. Brush each tooth with a toothbrush for 3 minutes. The control group brushes with clean water.

[0069] Step 4: After brushing, soak the teeth in artificial saliva. The tooth L value was measured using a colorimeter on days 0, 14, and 28. Color comparison was performed using the VITA Bleachedguide 3D-MASTER colorimeter, and the whitening degree was scored (0-5).

[0070] Step 5. Use the scoring method to determine the lightness value: hold the color chart at arm's length from the teeth, select group 0, 1, 2, 3, 4 or 5, and start from the darkest group; select saturation: based on the lightness, select the middle tone group (M) to determine the saturation, and spread the color chip like a fan, and select one of the three color chips; determine the color value: compare with the selected color chip, observe whether the color of the teeth is reddish or yellowish, select the final tooth color and score it.

[0071] Step 6: Calculate the results: SPSS statistical software was used to analyze the results and the independent sample t test was performed. If P < 0.05, the results were considered statistically significant.

[0072] Step seven, evaluate the results: if the L value / whitening score of the sample group after use is significantly greater than that before use, or the L value difference / whitening score difference of the sample group is significantly greater than the L value difference / whitening score difference of the blank group (P < 0.05), it means that the sample has whitening effect.

[0073] If the L value / whitening score of the sample group after use is not significantly greater than that before use, or the L value difference / whitening score difference of the sample group is not significantly greater than the L value difference / whitening score difference of the blank group (P>0.05), it means that the sample does not have the whitening effect.

[0074] Assume that the test groups of Examples 1 to 5 are respectively Test Group 1, Test Group 2, Test Group 3, Test Group 4 and Test Group 5, and the specific L value experimental results are shown in Tables 3 to 8:

[0101] The statistical results show that the toothpastes of Examples 1 to 5 are all effective in removing exogenous stains on teeth. They have a significant whitening and stain removal effect on bovine teeth after 14 days and 28 days, and can improve the color by more than 7 levels.

[0102] Therefore, it is believed that the mild stain-removing, whitening and deodorizing toothpaste containing diatomaceous earth and coconut shell carbon of the present invention has obvious deodorizing function.
