Xanthan gum is a white or light beige flowable powder, tasteless, odorless, non-toxic, safe to eat, soluble in water, and presents a polyanion in aqueous solution.
Mainly used in daily chemical products, such as toothpaste, using the advantages of xanthan gum stability and shear control to improve the paste state and easy filling; Zhongxuan xanthan gum has long-lasting viscosity, easy hydrolysis and superior Emulsification stability can make toothpaste easy to shape, good dispersibility, and improve toothpaste attachment; its unique high rheology can improve toothpaste filling and give a good taste.
In cosmetics and detergents, it can be quickly diffused and absorbed, making the skin feel smoother; in the shampoo, it has a suspension and stabilization effect and can increase foam;
In the mask, due to its good adhesion and high static viscosity, the mask is easier to adhere to the skin and easy to peel off.
