Abstract
Dentifrice compositions are provided having an effervescent and cleansing action. The dentifrice compositions are formed from an essentially anhydrous dentifrice base medium and an inorganic oxide material containing an adsorbed gas. Upon contact of the dentifrice composition with water, an effervescent action occurs as the gas is desorbed from the inorganic oxide material.
