Abstract
An oral composition, particularly a gel, is provided which includes at least 2%, preferably 6% or higher of hydrogen peroxide in a carrier stabilized by a triphenylmethane dye. Particularly useful as the dye are FD&C Blue 1 and FD&C Green 3 at levels ranging from 0.006 to 1 %. Further stability can also be achieved through use of a chelating acid, particularly phosphoric acid.
