Product Description

Toothpaste Grade Abrasive Precipitated Silica To Thicken For Toothpaste

Product Description∞ Chemical Formula: SiO2 (White Carbon Black)∞ CAS No:7631-86-9∞ Feature+Application

Y series for toothpaste grade is amorphous powder which is tasteless and insoluble in water or acid, showing as chemical inertness, with good compatibility with fluoride and other materials in toothpaste. The structure and particle size of silicon dioxide can be controlled by production condition. By aiming at different types of toothpaste, three kinds of products are made:abrasive type and thickening type.Specification
