The silicon dioxide used in FINE-SIL520A toothpaste is an amorphous powder, tasteless, insoluble in water or acid, chemically inert, and well miscible with fluoride and other raw materials in toothpaste. The structure and particle size of silicon dioxide can be controlled by production conditions. According to the different types of toothpaste, three types of products are produced: friction type, mixed type, and thickening type.
FINE-SIL520A series products have been tested and conform to the light industry standard QB/T2346-97 of the People's Republic of China
