Abstract
Hydro-activated and/or oxygen activated aqueous, enzymatic, antimicrobial dentifrices are stabilized against enzymatic activation prior to oral application of the dentifrice by incorporating a thickener into the dentifrice formulation so as to provide the formulation with an enzyme immobilizing viscosity which inhibits enzymatic action during processing and in the dentifrice package. An illustrative, thickened, enzymatic dentifrice with this enhancement contains glucose oxidase, glucose, lactoperoxidase and potassium thiocyanate together with carboxymethylcellulose in an amount to provide the dentifrice with a viscosity of at least about 800 centipoises.
