Description

Technical Field

[0001] The invention relates to a stain removing and whitening toothpaste and a preparation process 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] 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, the teeth may 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. Now, a stain-removing whitening toothpaste and its preparation process are urgently needed to solve the above problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a stain removing and whitening toothpaste and a preparation process thereof, so as to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention is realized by the following technical scheme: a stain removing and whitening toothpaste, comprising the following components in mass ratio: 20-30% perlite, 20-30% abrasive, 20-30% sodium phytate, 0.5-1.5% thickener, 20-30% hydroxyapatite, 20-30% moisturizer, 20-30% sodium tripolyphosphate, 0.1-0.2% sweetener, 2-4% stain remover, 0.1-0.2% antibacterial agent, 1.0-2.0% foaming agent, 1.0-1.5% toothpaste flavor, and the balance is deionized water; The friction agent is a mixture of granular silicon dioxide with a water absorption of 10-15 ml / 20 g and thickening silicon dioxide with a water absorption of 40-50 ml / 20 g in a mass ratio of 10-20:1.

[0007] Furthermore, the stain remover is a mixture of diatomaceous earth and phytic acid, the mass ratio of the diatomaceous earth to the phytic acid is 1.5-3:1.5; and the particle size of the diatomaceous earth is 10-30 μm.

[0008] Furthermore, the mass ratio of the diatomaceous earth to phytic acid is 2:1, and the particle size of the diatomaceous earth is 15 μm.

[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, glycerol and propylene glycol.

[0011] Furthermore, the perlite is an amorphous mixed glassy silicate from volcanic rock, the particle size of the hydroxyapatite is less than 60 nm, the perlite is in the form of flaky sheets with a particle size less than 100 μm, and the particle sizes of the sodium phytate and sodium tripolyphosphate are less than 70 nm.

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

[0013] Furthermore, the foaming agent is sodium lauryl sulfate, the covering agent is titanium dioxide, and the antibacterial agent is zinc citrate.

[0014] Furthermore, a preparation process of a stain removing and whitening toothpaste comprises the following steps: (1) Prepare the raw materials according to the above weight ratio; (2) dissolving the 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 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 perlite 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] Beneficial effects of the present invention: a stain-removing and whitening toothpaste and its preparation process. Compared with the prior art, the present invention uses perlite and hydroxyapatite as a polishing agent and a tooth repair material, respectively. On the one hand, the perlite used has a relatively high hardness due to a special process of high-temperature expansion and cooling, but has a fluffy structure and a relatively low density. During brushing with a toothbrush, it will decompose into a large number of tiny particles with a certain hardness, which can polish the concave and convex surfaces of the tooth surface to achieve the purpose of polishing and whitening without damaging the tooth enamel. On the other hand, the hydroxyapatite used is nano-grade and has good biocompatibility. It 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, which can simultaneously adsorb dirt, glucan and salivary protein on the tooth surface, reduce plaque formation, 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 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 in the process, and the six phosphate groups on the sodium phytate are not coplanar, so the sodium phytate and hydroxyapatite will not react quickly but only act slowly. Moreover, according to tests, although there will be a small loss of the sodium phytate content in the toothpaste, only a part of it is adsorbed. The 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 to refresh the breath.
