Abstract
A thixotropic, smooth-flowing liquid, bulk-water-free dentifrice gel/paste that contains a stable mixture of at least one of amylopectin containing discrete solid particles and modified amylopectin containing discrete solid particles, uniformly suspended in and wetted by an inert essentially anhydrous organic hydroxylated liquid matrix material, and which dentifrice gel/paste is characterized by a high surface sheen. Preferably, the modified homopolysaccharide discrete particles contain esterified amylopectin and/or esterified amylose. The dentifrice gel/paste can be used as a toothpaste, a bleaching gel and a brushing gel.
