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