Description

Technical Field

[0001] The invention relates to a toothpaste for whitening and removing bad breath and a preparation method thereof, belonging to the technical field of toothpaste. Background Art

[0002] Toothpaste is a paste product that is applied to the surface of human teeth by friction, with the main purpose of cleaning. It is usually in gel form and is usually applied to a toothbrush. With the help of the mechanical friction of the toothbrush, it cleans the surface of the teeth, cleans the teeth and their surroundings, and purifies and refreshes the oral cavity. In order to make teeth beautiful, protect gum health and prevent bad breath, tooth cleaning is the most important thing. Toothpaste has become a necessity in human daily life.

[0003] The residues of tobacco, tea, coffee, colored food and other substances in daily life are easily deposited on the tooth surface through the organic film of salivary protein on the tooth surface. If they are not cleaned promptly and effectively, after a long period of accumulation, they can cause the teeth to gradually turn yellow or even black, forming exogenous stains and spots on the teeth, which not only affects oral hygiene, but also affects the appearance of teeth. Whitening toothpaste is an oral care product for exogenous tooth coloring, which can remove stains and spots on the tooth surface to a certain extent.

[0004] Exogenous tooth stains are mainly caused by drinking pigmented beverages, eating pigmented foods, and smoking. Exogenous tooth stains are common in the population and affect appearance. Removing exogenous stains refers to removing stains on the surface of the acquired membrane and enamel of the tooth surface. It mainly uses ingredients with certain friction properties to remove stains located on the surface of the enamel, while removing endogenous stains requires drugs that can penetrate into the tooth surface tissue structure, such as hydrogen peroxide, to have a bleaching effect. Bleaching toothpaste can bleach teeth and can effectively remove smoke stains, tea stains, coffee stains, etc. on teeth. It is very popular among consumers at home and abroad, but chemical bleaching agents are often directly added to bleaching toothpaste, such as directly adding hydrogen peroxide. The hydrogen peroxide added in this form has a greater irritation to the oral cavity and makes the human body uncomfortable. Now there is an urgent need for a whitening and bad breath removal toothpaste and its preparation method to solve the above-mentioned problems. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention aims to provide a toothpaste for whitening and removing bad breath and a preparation method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical scheme: a toothpaste for whitening and removing bad breath, comprising the following components in mass ratio: hydrated silica 20-30%, pyrophosphate 2-4%, clove powder 20-30%, sodium phytate 20-30%, thickener 0.5-1.5%, hydroxyapatite 20-30%, modified glycerol 2-4%, humectant 2-4%, sodium tripolyphosphate 20-30%, antibacterial agent 0.1-0.2%, sweetener 0.1-0.2%, stain remover 2-4%, foaming agent 1.0-2.0%, preservative 1.0-1.5%, and the balance is deionized water; The modified glycerin is added with one or a combination of at least two of pearl powder, calcite powder and activated carbon before use; and the mass ratio of the modified glycerin to the additive is 3:1.

[0007] Furthermore, the stain remover is a mixture of diatomaceous earth and phytic acid.

[0008] Furthermore, the preservative is sodium benzoate, ethylparaben or chlorpyrifos.

[0009] Furthermore, the sweetener is one or more of saccharin sodium, xylitol and sucralose.

[0010] Furthermore, the moisturizing agent is one or more of sorbitol, propylene glycol, and polyethylene glycol 400.

[0011] Furthermore, the preparation method of sodium tripolyphosphate comprises the following steps: Step 1: mixing sodium carbonate and phosphoric acid to obtain a mixed slurry; Step 2, stirring the mixed slurry in step 1 to react, to obtain a slurry after reaction; Step 3, grinding the slurry after the reaction in step 2 through a colloid mill for 1 h to 2 h, and sieving; Step 4: Dry the sieved slurry, and polymerize the dried slurry at 40°C to 90°C for 30min to 60min; Step 5: Cool the polymerized slurry to room temperature, and calcine the cooled slurry to obtain sodium tripolyphosphate.

[0012] Furthermore, the thickener is one or more of xanthan gum, carrageenan and sodium carboxymethyl cellulose.

[0013] Furthermore, the foaming agent is one or more of sodium lauroyl aminate, sodium dodecyl sulfate and betaine.

[0014] Furthermore, a preparation process of a toothpaste for whitening and removing bad breath comprises the following steps: (1) Prepare the raw materials according to the above weight ratio; (2) dissolving a sweetener in water, adding the uniformly mixed sodium tripolyphosphate and sodium phytate under stirring, continuing to stir until the sodium tripolyphosphate and sodium phytate are completely dissolved, and then adding modified glycerin, a humectant and a liquid surfactant to obtain a mixture A; (3) Add abrasives, thickeners, moisturizers, foaming agents, stain removers, antibacterial agents and fragrances into purified water, stir and disperse to dissolve; (4) firstly mixing hydrated silica, pyrophosphate, clove powder and hydroxyapatite, then adding abrasive, thickener, solid surfactant and binder, and mixing to obtain mixture B; (5) Add the solution of step (3) to the solution of step (2) and step (4), stir evenly, adjust the pH to 6-7, and stir evenly to obtain a paste; (6) Grinding, degassing, and vacuuming to obtain toothpaste paste.

[0015] The beneficial effects of the present invention are as follows: a toothpaste for whitening and removing bad breath and a preparation method thereof. Compared with the prior art, the present invention aims at the situation that chemical bleaching agents are directly added to the existing toothpaste to cause great irritation to the oral cavity. The toothpaste composition with whitening function of the present invention adds biological enzymes that decompose the pigments and sugars remaining in the oral cavity or on the teeth to produce hydrogen peroxide with bleaching function, so that the pigments causing exogenous stains on the teeth can be removed and the endogenous stains can be removed, and the irritation to the oral cavity is also reduced; at the same time, for the pigments that cannot be decomposed, on the other hand, the hydroxyapatite used is nano-scale and has good biocompatibility, and can be deposited on the defective tooth surface, repair the fine cracks and gaps on the tooth surface, and strengthen the tooth enamel. Its nanostructure also has a strong adsorption effect, and can simultaneously adsorb dirt, glucan and salivary protein on the tooth surface, reduce the formation of bacterial plaque, play a certain role in preventing caries, and further protect the tooth enamel. The combined use of the two is conducive to improving the smoothness of the tooth surface and effectively reducing the re-formation of pigments and stains on the tooth surface; The sodium phytate and hydroxyapatite of the present invention work at the same time. This is because the sodium phytate and hydroxyapatite are pre-mixed with other materials respectively and then added for homogenization. The six phosphate groups on the sodium phytate are not coplanar. The sodium phytate and hydroxyapatite do not react quickly but only act slowly. Moreover, according to tests, although there is a small loss of the sodium phytate content in the toothpaste, only a part of it is adsorbed. The present invention can effectively remove exogenous pigment deposition and food residues on the tooth surface caused by foods such as cigarettes, tea, coffee, etc., and optimizes the taste of the toothpaste, which can refresh the breath. Clove has the effect of removing bad breath, because the fragrance of clove is relatively strong, and it can be used to treat oral diseases and eliminate bad smell in the mouth. Implementation
