Problems solved by technology

However, the chemical reaction itself is greatly affected by the oral environment, and the precipitated substances may not be able to block the dentinal tubules, and they are easily corroded and peeled off due to poor eating habits, so that the dentinal tubules are re-exposed to the sensitive oral environment; at the same time , the stubborn stains on the teeth cannot be effectively removed, which further hinders the desensitizer ingredients from acting on the sensitive area, thereby reducing the efficacy of the desensitizer
[0005] In addition, the existing desensitizing and whitening toothpaste cannot effectively solve oral ulcers and oral erosions caused by oral mucosal damage, and oral diseases such as gingival atrophy or damage cannot be solved by traditional anti-allergic toothpaste or traditional whitening toothpaste formula, and may even aggravate above symptoms

Embodiment 1

[0027] The preparation of embodiment 1 nanometer carbon crystal

[0028] Nano carbon crystal among the present invention adopts following method to prepare, and step is:

[0029] (1) Preliminary crushing: firstly, the diamond raw material is sent into the crushing cavity of the mechanical crusher, and is crushed by the high-speed rotating hammer head inside the crusher. The material stays in the crusher for re-crushing, and the granular material filtered through the finest sieve in the lower layer of the crusher is collected by the sieve plate (the mesh number of the sieve is not less than 32 mesh), while the material filtered by other mesh sieves can be used as Coarse materials are sold or used to prepare materials with other particle sizes; particles above 32 mesh are used for primary particle size separation by a multi-layer vibrating sieve machine. The vibrating sieve time is generally controlled at 30min~3h, and the mesh number of the sieve is sequentially arranged from 4...

Embodiment 2

[0036] A desensitizing and whitening toothpaste containing nano-carbon crystals, prepared from the following raw materials in weight percentage: 0.2% nano-carbon crystals (without surface functionalization treatment), 0.3% strontium chloride, 15% abrasive agent, hydroxyethyl Base cellulose 1.5%, Qingdai 0.2%, clindamycin 0.2%, carboxymethylcellulose sodium salt 1%, thickener 2%, sweetener 0.05%, sorbic acid 0.01%, wetting agent 16%, Sodium lauryl sulfate 2%, the balance is deionized water.

[0037] Calcium hydrogen phosphate dihydrate and calcium hydrogen phosphate anhydrous salt are mixed at a ratio of 7:1 to prepare friction agent.

[0038] The above-mentioned desensitizing and whitening toothpaste containing nano-carbon crystals is prepared according to the following steps:

[0039] (1) Use part of the deionized water to fully mix the nano-carbon crystals, strontium chloride and Indigo Naturalis, and then place them in a shaker to keep mixing to prevent precipitation;

[...

Embodiment 3

[0043] The difference between Example 3 and Example 2 lies in that: Example 3 uses nano-carbon crystals treated with surface functionalization to prepare desensitizing and whitening toothpaste. Specifically: a desensitizing whitening toothpaste containing nano-carbon crystals, which is prepared from the following raw materials in weight percentage: 0.2% of nano-carbon crystals treated with surface functionalization, 0.3% of strontium chloride, 15% of friction agent, hydroxyl Ethyl cellulose 1.5%, Indigo naturalis 0.2%, Clindamycin 0.2%, Carboxymethyl cellulose sodium salt 1%, Thickener 2%, Sweetener 0.05%, Sorbic acid 0.01%, Wetting agent 16% , Sodium lauryl sulfate 2%, and the balance is deionized water.

[0044] The nano-carbon crystals are treated with surface functionalization, and the treatment process is as follows: the nano-carbon crystals are placed in concentrated HNO with a mass ratio of 1:3 3 / Concentrated H 2 SO 4 In the mixed solution, heat and reflux at 90°C ...

Abstract

The invention discloses a desensitizing and whitening toothpaste containing nano carbon crystal, and belongs to the fields of oral health and health care. The desensitizing and whitening toothpaste is prepared from the following raw materials in percentage by weight: 0.2%-1% of nano carbon crystal, 0.3%-6% of strontium chloride, 10%-45% of an abradant, 1.5%-2% of hydroxyethyl cellulose, 0.1%-0.5% of indigo naturalis, 0.2%-0.8% of clindamycin, 1%-2% of sodium carboxymethylcellulose, 2%-5% of a thickener, 0.05%-0.1% of a sweetening agent, 0.01%-0.05% of a preservative, 15%-25% of a wetting agent, 1.5%-3.5% of sodium lauryl sulfate and the balance of deionized water. The surface-functionalized nano carbon crystal is added to the desensitizing and whitening toothpaste containing the nano carbon crystal, so that the desensitizing and whitening toothpaste has obvious whitening, antiallergic and antibacterial effects; the tooth whitening time can be greatly shortened; the bacteria on the tooth surfaces are effectively eliminated; and a long-term antibacterial effect can be maintained.

Description

technical field [0001] The invention belongs to the field of oral hygiene and health care, in particular to a desensitizing and whitening toothpaste containing nano carbon crystals. Background technique [0002] Stubborn stains on teeth and tooth sensitivity are the main oral problems people face. Tooth hypersensitivity is caused by tooth pain caused by direct exposure of dentinal tubules to external physical and chemical stimuli in the oral environment. Deposits of stubborn stains on teeth are caused by rough tooth surfaces and insufficient tooth cleaning. [0003] In order to solve the above problems, in the prior art, whitening agents and desensitizing agents are usually added to toothpaste to achieve whitening and antiallergic effects. Whitening agents are divided into two categories according to their functions: one is the whitening agent mainly containing inorganic salts, which uses itself to contain high-hardness coarse particles to erase stains on the tooth surface...
