Problems solved by technology

The powder abrasives and surfactants with foaming properties in ordinary toothpaste (tooth cleaning type) help to remove the soft dirt on the tooth surface under the mechanical friction of brushing teeth. Toothpaste produced all over the world consumes a lot of money every year. Abrasives, which cause a lot of pollution

Embodiment 1

[0031] The formulation of toothpaste with no or less abrasives is as follows: (percentage)

[0032] Abrasive 0-20

[0033] Humectant: Glycerin 0-30

[0034] Thickener: sodium carboxymethyl cellulose 0-5

[0035] Surfactant: Sodium Lauryl Sulfate 1-20

[0036] Fragrance 0-2

[0037] Sweetener 0-0.25

[0038] Preservatives 0-0.5

[0039] water balance

[0040] The formula of small test sample (percentage content)

[0041]

[0042] The small test samples of the above formulas can all be made into toothpaste suitable for use.

[0043] Toothpaste production process: mix surfactant (such as sodium lauryl sulfate) with thickener (such as sodium carboxymethyl cellulose) (A), dissolve humectant in water (if the formula contains abrasive , disperse the abrasive in water), mix A with the above aqueous solution, call this mixture B, stir B, add sweetener and essence and preservative to B. Continue to stir evenly to obtain the toothpaste material, and send the mixed toothpaste ...

Embodiment 2

[0045] Example 2 Toothbrush containing abrasives

[0046] Bristle filament manufacturing can be achieved through a wire extrusion machine, polymers in granular form include polyamide, polyester, polyolefin, fluoropolymer, polyurethane, polyvinyl chloride, polyvinylidene chloride, styrene polymer or Copolymers, and any compatible combination of them, can be supplied to the extruder from the feed unit in proportion, and the abrasive can be supplied to the extruder at the other inlet of the extruder. At high temperature, the polymer and the abrasive Mix according to a certain ratio, such as mixing nylon and calcium carbonate according to the ratio of 98-80:2-20, and then output the mixture quantitatively, through the spinning and cooling process, we can get the bristles of various shapes we want .

[0047] The abrasive used includes one or more of calcium carbonate, calcium bicarbonate, calcium phosphate, calcium hydrogen phosphate, calcium pyrophosphate, water-soluble sodium me...

Abstract

The present invention relates to a tooth-paste containing no abrasive agent or containing small quantity of abrasive agent and its matched toothbrush containing abrasive agent. Said toothpaste is characterized by that its abrasive agent content is reduced to 0-20% from original 50%, and its toothbrush is characterized by that in the course of making toothbrush mustache about 2%-20% of abrasive agent is added into high polymer, then the high polymer in which the abrasive agent is contained is undergone the processes of spinning and forming to obtain toothbrush mustache, then the toothbrush mustache also is undergone the grinding process so as to make the abrasive agent be bared on the surface of toothbrush mustache.

Description

technical field [0001] The invention relates to a toothpaste and a toothbrush used in conjunction with it, specifically a toothpaste containing no or little abrasive in the formula of the toothpaste and a toothbrush containing abrasive in the bristles of the toothbrush. The invention belongs to the field of toothpaste and toothbrush. Background technique [0002] In daily life, everyone is inseparable from brushing their teeth. The invention and continuous innovation of small toothbrushes and toothpastes reflect the progress of social civilization and technology. The development trajectory from weak to strong. Although my country was the first country to use toothbrushes, the toothpaste as the main oral dentifrice was an imported product, which was imported into my country during the Guangxu period of the Qing Dynasty. Before the introduction of toothpaste, the toothpaste used by people to brush their teeth was a kind of green salt, which was a kind of salt for brushing te...
