Good cleaning performance: Toothpaste grade silica, as a friction agent, can effectively remove food residues, pigments, and dental plaque on the surface of teeth, while its gentle nature does not cause irritation to teeth and gums.
Appropriate wear resistance: Its wear resistance coefficient matches the teeth, which can reduce the wear on the teeth and protect the enamel of the teeth during the cleaning process.
Excellent stability: chemically stable, does not react with other ingredients such as fluoride, Chinese herbs, spices, etc. in toothpaste, ensuring the quality and performance of toothpaste remain stable during long-term storage.
Good compatibility: It has good compatibility with various ingredients in toothpaste, such as wetting agent, essence and surfactant, which is conducive to fragrance release and foam dispersion. It is also suitable for making transparent toothpaste.
Safe and non-toxic: Silicon dioxide used in toothpaste is a widely used safe and non-toxic food additive and pharmaceutical excipient in countries around the world. It does not react with gastric juice or saliva in the human body and is harmless to human health.
Good thixotropy and thickening: Silicon dioxide can provide good pseudoplasticity and thixotropy for toothpaste. During the production and use of toothpaste, the paste has good pseudoplasticity and thixotropy, can withstand mechanical processing, and the components will not be damaged. During the fluidization process, the decrease in paste viscosity is beneficial for reducing the friction during filling and improving production efficiency; After resting, the apparent viscosity of the paste gradually increases, the shape of the tube becomes fuller, and the extruded toothpaste has strong adhesion.
Low density: The density of silica used in toothpaste is lower than other materials. With the same weight of paste, more toothpaste can be produced, which helps to reduce production costs.
Strong adsorption: With a large specific surface area, it has a strong ability to adsorb fragrances, making the aroma of toothpaste soft and long-lasting. It can also improve the glossiness of the paste and make the taste more delicate.
