Toothpaste Grade Silica

◆Description of products

Precipitated toothpaste grade silica is amorphous white powder, are soluble in water and acid, with  chemical inertness,and has good compatibility with other materials and fluoride in toothpaste, can annually produce 1500 tons in 2013.These products are mainly used in toothpaste, food, medicine and so on.

◆Description of products

Silica can be used as filler and abradant in transparent coloring or opaque toothpastes. Such toothpastes enjoy good flexibility and dispensability, and the paste show great smoothness, softness and abrasiveness. The silica can maintain the medicine property of medicinal toothpastes, and it demonstrates nice compatibility with fluoride in the paste which can avoid insoluble salts caused by calcium salt as abradant.
