a novel, nonionic, rheology modifier, baed onpolyvinylpyrrolidone, thickens challenging formulations, such anhydrous formulations. It does not require neutralization; is highly salt tolerant and delivers a desirable texture to toothpaste formulations. As FlexiThix™ polymer is synergistic with acrylate thickeners, it is a good choice for anhydrous toothpaste formulations. When combined with acrylate thickeners, the thickener combination results in higher viscosity than either thickener alone at the same use levels.
