Abstract

The invention belongs to the technical field of toothpaste preparation, and particularly relates to antiallergic photocatalyst whitening toothpaste and a preparation method thereof. The toothpaste comprises the components of a photocatalyst, bioactive glass, an abrasive, a foaming agent, a thickening agent, a moistening agent, a coloring agent and a solvent, wherein the photocatalyst and the bioactive glass are synchronously added to the formula; the photocatalyst is capable of performing oxidization under the effect of visible light so as to rapidly whiten teeth; the bioactive glass is in contact with saliva to form an alkaline environment in which calcium and phosphonium ions can be released to form hydroxyapatite protecting membranes on the surfaces of the teeth, so that demineralizedteeth can be mineralized again, dentinal tubule exposed from the teeth due to the corrosion of acidic substances produced by the photocatalyst can be closed, and the stimulus of outside to dental nerve can be avoided, and as a result, the rapid antiallergic effect can be realized while the whitening is achieved; and the potassium ions released by the bioactive glass are capable of adjusting the transmittance of the dentinal tubule, and the stimulus of the outside to pulp nerve through the dentinal tubule can be reduced, and thus hemodia can be further treated.

Description

technical field

[0001] 本发明属于牙膏制备技术领域,尤其涉及一种抗过敏光触媒美白牙膏及其制备方法。 Background technique

[0002] 市场上有多种美白牙膏,根据美白原理不同,主要可以分为两类:靠物理摩擦剂美白和靠化学药剂美白。物理美白是在牙膏中加入摩擦剂祛除牙齿表面附着的色斑和结石,效果不明显,如长期如此刷牙,会对牙齿造成不同程度的磨损;化学美白主要是添加过氧化物来氧化分解牙面色斑,容易造成牙釉质损伤。

[0003] 光触媒是一种以纳米级二氧化钛为代表的具有光催化功能的半导体材料的总称,将光触媒材料应用到传统牙膏中,刷牙时光触媒在紫外光及可见光的作用下,产生出氧化能力极强的自由氢氧基和活性氧,可彻底氧化分解附着在牙齿上的牙菌斑和牙齿色素沉淀,起到高效美白牙齿的作用。但光触媒产生强氧化作用的同时所产生的酸性物质会使牙齿发生脱矿现象,使牙齿外层牙釉质流失,内层较软的牙本质外露,通往牙神经的牙小管也会同时外露,冷热刺激会通过牙小管刺激牙神经,引起牙齿敏感酸痛。 Contents of the invention

[0004] 为解决上述现有技术的不足,本发明提供了一种抗过敏光触媒美白牙膏及其制备方法。

[0005] 本发明的技术方案:

[0006] 一种抗过敏光触媒美白牙膏,按重量份包括以下组分:光触媒0.1~5份、生物活性玻璃0.5~5份、摩擦剂5~25份、发泡剂0.5~5份、增稠剂0.1~1份、保湿剂1~15份、着色剂0.1~1份和溶剂20~70份。

[0007] 进一步的,所述抗过敏光触媒美白牙膏按重量份包括以下组分:光触媒1~3份、生物活性玻璃1~3份、摩擦剂10~20份、发泡剂1~3份、增稠剂0.5~0.8份、保湿剂5~10份、着色剂0.5~0.8份和溶剂25~60份。

[0008] 进一步的,所述抗过敏光触媒美白牙膏还包括如下重量份的组分:中和剂0.1~1份、甜味剂0.01~1份和香基0.2~2份。

[0009] 进一步的,所述抗过敏光触媒美白牙膏还包括如下重量份的组分:中和剂0.5~0.8份、甜味剂0.1~0.5份和香基0.4~1.6份。

[0010] 进一步的,所述光触媒为锐钛矿晶型纳米二氧化钛粉末,二氧化钛粒径为5~50nm。 [0...
