Hydrated Silica TP 48 as thickening agent in Toothpaste dentaltifrice
Chemical Properties
Hydrated silica in toothpaste TP 48 is a synthetic silica with superior abrasive white powder and compatibility with other ingredients.
Hydrated Silica TP 48 is a highly purified form of hydrated silica that is widely used as a thickening agent in toothpaste and dentifrice formulations. Its unique properties make it highly effective in improving the viscosity, texture, and overall stability of toothpaste products. Here’s a detailed overview of Hydrated Silica TP 48 in the context of toothpaste and dentifrice.
