Abstract:
An oral care composition comprising:(a) chlorine dioxide, (b) ethoxylated hydrogenated castor oil having an ethoxylation number of about 35 to about 60, (c) flavoring agent, (d) pH buffer, (e) sweetener, (f) glycerin, and (g) water; wherein the pH of the composition is above about 6.3 said oral care composition being an oil-in-water emulsion said chlorine dioxide being stabilized chlorine dioxide in the form of about 0.001% to about 0.1% of a sodium chlorite solution, which, when exposed to the mouth, pH less than about 6.3, forms about 1 ppm to about 75 ppm molecular chlorine dioxide by the degradation of the sodium chlorite, said ethoxylated hydrogenated castor oil and said flavoring agent both being in liquid form and admixed to form a microemulsion of ethoxylated hydrogenated castor oil and flavoring agent with said flavoring agent microencapsulated within said ethoxylated hydrogenated castor oil and said glycerin mixed with said microemulsion to form a flavor component, said microencapsulation forming a stable composition protecting the flavor from free chlorine and/or chlorine dioxide oxidation, production of chlorine odor and yellowing discoloration.
