         7 . The oral care composition of  claim 6 , wherein the non-aqueous liquid comprises triacetin, and wherein the oral care composition comprises at least 0.01% triacetin, based on the total weight of the oral care composition. 
     
     
         8 . The oral care composition of  claim 6 , wherein the non-aqueous liquid comprises PGDA and wherein the oral care composition comprises at least 0.01% PGDA, based on the total weight of the oral care composition. 
     
     
         9 . The oral care composition of  claim 1 , wherein the oral care composition comprises an equal or greater amount of non-aqueous liquid to polyvinylpyrrolidone copolymer structure-building agent, such that a mass ratio of the non-aqueous liquid to the polyvinylpyrrolidone copolymer structure-building agent is 50:50 or greater. 
     
     
         10 . The oral care composition of  claim 1 , wherein a mass ratio of the non-aqueous liquid to the polyvinylpyrrolidone copolymer structure-building agent is from about 90 to 50 non-aqueous liquid to about 10 to 50 polyvinylpyrrolidone copolymer structure-building agent. 
     
     
         11 . The oral care composition of  claim 1 , wherein the non-aqueous liquid has a log P value of from about −2.0 to about 2.0 
     
     
         12 . The oral care composition of  claim 1 , wherein a viscosity of the oral care composition is from about 50,000 to about 500,000 cPs. 
     
     
         13 . The oral care composition of  claim 1 , further comprising at least one ingredient from the group consisting of: a whitening agent, a surfactant, an antioxidant, a flavoring, a sweetener, a pH modifiers, an abrasive, an anticalculus agent, a source of fluoride ions, a stannous ion source, a colorant, a dye, and a pigment. 
     
     
         14 . The oral care composition of  claim 13 , wherein the at least one ingredient is orally acceptable. 
     
     
         15 . The oral care composition of  claim 13 , wherein the oral care composition is a dentifrice. 
     
     
         16 . A non-aqueous oral care composition, comprising:
 from about 0.01% to about 60% of peroxydone complex, based on a total weight of the oral care composition;   from about 0.01% to about 60% of a amphiphilic copolymer structure-building agent, based on the total weight of the oral care composition; and   from about 0.01% to about 99% of a non-aqueous liquid dispersant, based on the total weight of the oral care composition.   
     
     
         17 . The non-aqueous oral care composition of  claim 16 , wherein the amphiphilic copolymer is a polyvinylpyrrolidone vinyl acetate copolymer.
