Problems solved by technology

As another example, Chinese herbal toothpaste has the advantages of fragrant smell and remarkable curative effect, but the preservation time of organic matter in toothpaste is a big difficulty. For example, magnolol in Magnolia toothpaste has antibacterial and anti-inflammatory effects, and after a period of deterioration, it will cause The whole stick of toothpaste becomes waste

Embodiment

[0027] Silver is in a nano state, and its mechanism of killing (inhibiting) bacteria is: silver in a nano state has a large atomic surface activity. Through the action of saliva in the mouth, silver ions (Ag+) with positive electrons will adsorb negatively charged bacteria to the surface and pass through the cell membrane. Combining with deoxyribonucleic acid (DNA) in bacteria, it destroys the electrical and physical properties of bacteria, and makes the functional cells lose their ability to reproduce, thus achieving the effects of preventing oral ulcers, preventing dental caries, and antibacterial health care.

Abstract

The present invention discloses a nano colloidal silver toothpaste, firstly, the silver is used as electrode, and the colloidal silver particles are prepared by means of electric spark bombardment, then are directly added into the toothpaste. Its raw material includes dihydrated calcium hydrophosphate, sodium dodecyl sulfate, 70% sorbiotol, glycerine, sodium carboxy methyl cellulose, sodium pyrophosphate, gluside, essence and deionized water, and the nano colloidal silver is added into the above-mentioned raw material according to a certain proportion, and can be made into the invented toothpaste. It can prevent and cure caries, clean tooth and attain the goal of preventing stomatocace and protecting oral cavity.

Description
