Embodiment 1-1

[0020] 1) After removing the residual meat, attachments and cuticles of the oyster shells, the oyster shells are coarsely crushed by dry method with a hammer crusher to obtain coarse oyster shell powder with a diameter of 1 mm;

[0021] 2) Add 20g of oyster shell coarse powder and 80g of water to make a slurry with a mass percentage concentration of 20%, add 0.06g of sodium pyrophosphate and 0.08g of disodium ethylenediaminetetraacetate for wet grinding, and dry to obtain granules Biomineralized friction agent with a diameter of 0.1 μm.

Embodiment 1-2

[0023] 1) After removing the residual meat, attachments and cuticles of the mussel shells, the mussel shells are coarsely crushed by a hammer crusher in a dry method to obtain coarse mussel shell powder with a diameter of 3 mm;

[0024] 2) Add 60g of mussel shell coarse powder and 40g of water to make a slurry with a mass percentage concentration of 60%, add 0.06g of sodium pyrophosphate and 0.012g of disodium ethylenediaminetetraacetic acid for wet grinding, and dry to obtain granules Biomineralized friction agent with a diameter of 50 μm.

Embodiment 1-3

[0026] 1) After removing the residual meat, attachments and cuticles of the scallop shells, the scallop shells are roughly crushed by dry method with a hammer crusher to obtain coarse scallop shell powder with a diameter of 1.5 mm;

[0027] 2) Add 30g of scallop shell powder and 70g of water to make a slurry with a concentration of 30% by mass, and add 0.06g of sodium pyrophosphate and 0.03g of disodium ethylenediaminetetraacetic acid for wet grinding, and then dry it to obtain Biomineralized friction agent with a particle size of 10 μm.

Abstract

The invention discloses toothpaste containing a biological mineralized abradant. The toothpaste provided by the invention is a mixture, which comprises 24-42% of the biological mineralized abradant, 0.3-4% of silicon dioxide, 8-24% of sorbierite, 0.3-4% of lauryl alcohol sodium sulphate, 0.3-1.6% of sodium carboxymethyl cellulose, 0.3-1.2% of sodium monofluorophosphate, 0.3-2.1% of benzoic acid sodium, 0.03-0.2% of saccharine sodium, 0.2-1.4% of spice and 25-38% of water. The toothpaste takes waste shells as raw materials to prepare the biological mineralized abradant, and has the advantages of wide range of raw material source, simple preparation process, good safety and high nontoxicity, and the like compared with the prior art; due to a special column-shaped and layered grain structure and the rich contain of natural organic matters, the compatibility of the abradant, fluoride and the spice is improved; the prepared abradant has extremely strong biological compatibility, and great adhesive force with tooth sections, so that the toothpaste can be deposited on tooth sections during tooth brushing.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, in particular to a toothpaste containing a biomineralized friction agent. Background technique [0002] Toothpaste is currently the largest oral hygiene product. Domestically produced toothpaste is mainly made of raw materials such as abrasives, foaming agents, thickeners, oxidants, spices, etc. Among them, abrasives account for the largest proportion, which mainly cleans teeth without wearing them. Toothpaste on the existing market mostly adopts single-component silicon dioxide, calcium hydrogen phosphate, calcium carbonate, aluminum hydroxide and other hard, high-density abrasives as abrasives. Because calcium carbonate is cheap, it still occupies a large proportion in the market; but using ordinary calcium carbonate as the abrasive of toothpaste has the problem of removing peculiar smell in the oral cavity or deodorizing and descaling effects. It is also difficult to disperse the t...
