Food Grade Toothpaste Thickenning Hydrated Precipitated Silica Powder
This thickenning silicon dioxide is a high structure product with high oil absorption value, large specific surface area, high refractive index and light transmittance, generally greater than 90%. It has good compatibility, extremely fine particle size and superior water force.
JS-260 used for toothpaste is a precipitated silica, which has good absorption and high hardness. As a thickening agent and abrasive agent, it helps improve the viscosity, suspension and smoothness of toothpastes and make them easier to use. Furthermore, the surface hydrophobicity of this agent helps provide excellent dry and wet non-sticking. Additionally, it improves the abrasion resistance, imparts gloss and prevents precipitation by keeping the toothpaste homogeneous. JS-260 also helps reduce foam of toothpastes and improve the content resolution. Furthermore as a fine abrasive, it also helps to polish and remove the turbidity on the surface of the teeth.
