Abstract

The invention discloses novel toothpaste with graphene oxide and a preparation method thereof, and belongs to the technical field of daily chemical products. The toothpaste is technically characterized by being prepared from 0.01-1.5% of graphene oxide, 0.1-0.85% of ionic liquid and the balance additives, wherein the additives comprise an abrasive agent, a wetting agent, a surfactant, a binding agent, a stabilizing agent, spice, a sweetening agent and water. The graphene oxide is applied in toothpaste components for the first time, and the application range of the graphene oxide in daily chemical products is expanded again. The toothpaste with the graphene oxide has the strong bacteriostasis effect on staphylococcus aureus, escherichia coli, porphyromonas gingivalis, prevotella intermedia and actinobacillus actinomycetemcomitan.

Description

technical field [0001] The invention relates to the field of daily chemical products, more particularly to a toothpaste, in particular to a novel toothpaste containing graphene oxide and a preparation method thereof. Background technique [0002] Toothpaste is an indispensable thing in people's daily life, and there are countless types and brands of toothpaste on the market. Professional medical statistics found that in China, 90% of adults have oral problems of varying degrees, such as oral ulcers, swollen gums, bleeding, atrophy, etc., and the above-mentioned problems are spreading rapidly. These oral "small problems" Although it is not enough to go to the hospital, it has greatly troubled people's emotions, resulting in consumer demand for oral problems. [0003] In 2004, British scientists Geim et al. prepared monolayer graphene by mechanical exfoliation method, which triggered a research upsurge on graphene. Graphene is a carbonaceous material with a two-dimensional p...
