Abstract

Oral care compositions comprising chlorine dioxide and excipients, including flavoring agents and ethoxylated hydrogenated castor oil having ethoxylation numbers from about 35 to about 60. The flavoring agents become bound to the hydrophobic end of the ethoxylated hydrogenated castor oil molecule and become encapsulated within the molecule as the hydrophilic end of the ethoxylated hydrogenated castor oil wraps around the flavoring agent. The flavoring agent does not undergo oxidation. The oral care compositions do not develop either a chlorine odor or yellowing discoloration. The oral care compositions can be packaged, stored, sold and used in a single package.
