Description
Technical field
The invention belongs to field of oral care, and in particular to a kind of antiallergic sense toothpaste.
Background technique
Sensitivity of tooth is outside being exposed to because of the canaliculi dentales on dentine, so that dentine is to cold and hot sour-sweet or brusher
The pain symptom that the generations stimulation such as agomphiasis work occurs.Anti- sensitive technology for toothpaste mainly has: one, blocking dentinal tubule；
Two, the sensibility of Intradental nerve is reduced by potassium ion.
The technology of mode two can only benumb nerve in short term, cannot have long-range lasting in the presence of cannot really completely cut off environmental stimuli
Curative effect.Mode one can block dentinal tubule to a certain extent at present, but most closure and insecure, cause originally
The aperture blocked exposes again, and sealing ratiod reduces, and anti-sensitizing effect also decreases.
Microcrystalline cellulose is made of plant fiber through sour water solution, and CN1325676A, which discloses one kind, to prevent tooth from grinding
Damage, and can clean the novel toothpaste of tooth, and it for 15~50 μm of microcrystalline cellulose is grinding agent which, which uses partial size, but this article
It offers and does not disclose whether its toothpaste has anti-sensitive property.
Hydroxyapatite is a kind of bone renovating material of classics, and CN105640788A discloses a kind of hydroxyapatite tooth
Cream, the hydroxy agustite tooth-paste include micron order hydroxyapatite, nanometer hydroxyapatite and fluoride.Although the toothpaste can
Dentine is effectively repaired, but there are excess intake fluorine, leads to the problem of dental fluorosis.
Summary of the invention
According to above-mentioned the deficiencies in the prior art, has the object of the present invention is to provide one kind and preferably block dentinal tubule
Antiallergic sense toothpaste.
To achieve the above object, the technical solution adopted in the present invention is as follows:
A kind of antiallergic sense toothpaste, including rubbing agent and water, it is characterized in that: the rubbing agent is mainly by for blocking tooth sheet
The microcrystalline cellulose and hydroxyapatite of matter tubule form, based on the weight of antiallergic sense toothpaste, the content of the microcrystalline cellulose

1:1.5。
Preferably, the antiallergic sense toothpaste also contains moisturizer, thickener, foaming agent, sweetener, aromatic, bacteriostatic agent
At least one of with pigment.
Preferably, based on the weight of antiallergic sense toothpaste, the content of the moisturizer is 20%~75%, the thickener
Content is 0.5%~2%, and the content of the foaming agent is 0%~3%, and the content of the sweetener is 0~0.5%, the virtue
The content of pastil is 0~2%, and the content of the bacteriostatic agent is 0~0.5%, and the content of the pigment is 0~0.5%.
Preferably, the moisturizer is selected from sorbierite, glycerol etc.；The thickener is selected from cellulose gum, modified cellulose
Glue, xanthan gum etc.；The foaming agent is selected from laruyl alcohol sodium sulfovinate, Cocoamidopropyl betaine etc.；The sweetener is selected from
Saccharin sodium, Sucralose etc.；The aromatic is selected from natural perfume material, synthetic perfume or essence；The bacteriostatic agent is selected from benzoic acid
Sodium, methyl p-hydroxybenzoate etc..
The modified cellulose gum such as carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, Methyl cellulose
Element, ethyl cellulose etc..
The preparation method of above-mentioned antiallergic sense toothpaste, comprising:
(1) moisturizer and sweetener are first dissolved in water, obtain liquid phase；
(2) liquid phase is added in rubbing agent and thickener again, be mixed；
(3) foaming agent, aromatic, bacteriostatic agent and pigment is then added, degassing obtains the antiallergic sense toothpaste.
It is a kind of for blocking the composition of dentinal tubule, sign point in: the composition mainly by microcrystalline cellulose and
Hydroxyapatite composition, wherein the weight ratio of the microcrystalline cellulose and hydroxyapatite is 1:0.2~1:1.5.
Above-mentioned composition is preparing the application in antiallergic sense toothpaste as the active constituent for blocking dentinal tubule.
Preferably, weight percent content of the composition in antiallergic sense toothpaste is 15%~20%.
Antiallergic sense toothpaste of the invention reaches 70~90% to the sealing ratiod of dentinal tubule, and sealing ratiod can reach after acid etching
60~80%, and it is not necessary that fluoride is added.
In the present invention, the fiber strip structure (see Fig. 1) of microcrystalline cellulose can form frame structure, and hydroxyapatite is then
It is filled in frame structure, dentinal tubule is deposited on as reinforced concrete, the work for blocking dentinal tubule is played in collaboration
With more longlasting firm closure dentinal tubule is higher than independent microcrystalline cellulose, hydroxy-apatite to the sealing ratiod of dentinal tubule
Sealing ratiod after the sealing ratiod and acid etching of stone or bio-vitric.

Block test
Toothpaste prepared by embodiment 1-3, comparative example 1-5 is as follows to the closure test process of dentinal tubule:
1. taking the fresh ox incisor cutting polishing pulled out, it is fabricated to dentine block, and observe under polarization microscope, really
It is abundant to protect canaliculi dentales exposure.
2. several pieces of dentine samples are assigned randomly to blank control group, negative control group, positive controls and experiment
In group.
3., as non-process area, half region in addition, which is used as, brushes teeth with the dentine sample in tape-stripping half region
Experiment process area.
4. blank control group uses common commercial toothpastes, positive controls use pair using deionized water, negative control group
Toothpaste prepared by ratio 1-5, experimental group use toothpaste prepared by embodiment 1-3.Each group dentine sample is placed in accordingly
It in treatment conditions, is brushed teeth using automation Tooth-brushing device, is then sufficiently cleaned with deionized water, be soaked in artificial saliva later
60min.It repeats the above steps 6 times.
5. dry dentine sample is taken out to observe under a scanning electron microscope, it is each respectively at treatment region and non-process area
The picture (2000 times) for taking three visuals field carries out exposed canaliculi dentales and counts C.
6. calculating each group canaliculi dentales sealing ratiod R:
R (%)=/ ∑ non-process area C × 100 (∑ non-process area C- ∑ treatment region C)
7. the solution of the pH ≈ 3 configured again with citric acid impregnates sample 10 minutes.
8. repeating 5,6 steps, sealing ratiod R is calculated.
| Toothpaste sample | Sealing ratiod | Sealing ratiod after acid etching | Retention rate |
| Embodiment 1 | 88% | 79% | 90% |
| Embodiment 2 | 80% | 71% | 89% |
| Embodiment 3 | 72% | 64% | 89% |
| Comparative example 1 | 63% | 45% | 71% |
| Comparative example 2 | 55% | 37% | 67% |
| Comparative example 3 | 64% | 47% | 73% |

| Comparative example 5 | 51% | 30% | 59% |
| Negative control group | 34% | 18% | 53% |
| Blank control group | 2% | 1% | 50% |
Sealing ratiod/sealing ratiod × 100% after retention rate=acid etching
Toothpaste of the invention reaches 70~90% to the sealing ratiod of dentinal tubule it can be seen from experimental result, acid etching
Sealing ratiod can reach 60~80% afterwards, compared with independent microcrystalline cellulose or hydroxyapatite, have more longlasting firm closure
Effect.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
