Dihydromyricetin-containing toothpaste with functions of whitening and repairing teeth and preparation method thereof

Abstract

The invention discloses dihydromyricetin-containing toothpaste with functions of whitening and repairing teeth and a preparation method thereof. The preparation method comprises the following steps: adding purified water into a pre-dissolving pot, adding water-soluble raw materials, such as dihydromyricetin, sodium phytate and the like, into the pre-dissolving pot, and stirring the mixed solutionto form an aqueous solution; adding a toothpaste abrasive into a pre-mixed powder pot, and performing uniform dispersing to prepare a powder material; pumping a humectant into a pre-dispersing pot, dispersing an adhesive thickening agent into the pre-dispersing pot, feeding materials into a vacuum paste maker, performing homogenizing, grinding and uniform stirring, and performing cooling; adding afoaming agent into the vacuum paste maker, stirring the mixture at medium speed until the mixture is homogenous, feeding other substances into the mixture, and performing stirring; filling paste after the paste is qualified in sampling and inspection to obtain the toothpaste with functions of whitening and repairing teeth. The toothpaste can be used for quickly repairing and removing new surfacecharges outside stains dirt membranes, so that the normal balance of the tooth surface can be maintained, harmful flora can be inhibited, and secondary dyeing factors, such as dietary and other external colors, can be prevented.

Description

technical field [0001] The invention relates to the field of toothpaste, in particular to a dihydromyricetin-containing tooth whitening and repairing toothpaste and a preparation method thereof. Background technique [0002] In the oral environment, tooth surface stains are often mixed with extrinsic stains on the tooth surface, and their formation is based on acquired pellicles. The salivary acquired membrane is formed by the selective adsorption of glycoproteins in saliva to the tooth surface. It is a thin layer of acellular, unstructured, homogeneous organic membrane with a thickness of about several microns. Acquired films contain substances such as amino acids, proteins, carbohydrates and lipids, and can be formed on the surfaces of tooth surfaces and fillings, calculus, restorations and appliances in the oral cavity through the action of ionic charges. After the acquired film is formed, bacteria and dietary pigments such as tea, coffee and soy sauce can adhere to it t...

Problems solved by technology

[0003] The present invention improves on the prior art. There are three main whitening principles of the existing tooth whitening and repairing toothpaste: physical method to increase the rubbing strength of toothpaste, chemical method to acid-etch the dirt layer or direct peroxide bleaching and biological enzyme method to digest stains Among them, the first two are the ones with obvious clinical curative effect, especially the chemical method has the best clinical effect and the most citations, while the latter enzymatic method has not enough effect and technical maturity

However, the existing most effective chemical whitening toothpaste removes part of the acquired stain film, and it will cause corrosion to the glaze of the tooth itself even deeply, forming a new rough surface with free radicals and holes. If you dispose of it at this time Not good, it is easier to acquire foreign substances and pigments, form new stains and scale films, and rebound quickly, and the damage to the gums and tooth bodies will be more serious due to repeated use
