  • Oral compositions
    Patent number: 6022528
    Abstract: The present invention relates to an effervescent oral care composition with improved interproximal delivery properties. The composition comprises a first composition with about 2.5% by weight of an alkalimetal bicarbonate and a second composition with an acidic compound. Upon bringing the two compositions into contact with each other, e.g. by extruding them from a multicompartment container through a single outlet orifice, the alkalimetal bicarbonate and the acidic compound react with each other, causing an effervescent effect. By using 0.02% to less than 0.5% by weight, calculated on the total weight of the oral care composition, of the acidic compound, the interproximal delivery properties of the composition are significantly improved.
