Abstract
Abstract An oral composition such as a dentifrice or mouthwash, containing an aqueous phase of water and as solubilizing agent propylene glycol, dipropylene glycol, methyl cellosolve, ethyl cellosolve, olive oil, castor oil, amyl acetate, ethyl acetate, glyceryl tristrearate or benzyl benzoate mixed with at least one glycerine and sorbitol, a substantially water-insoluble noncationic antibacterial antiplaque agent, such as 2,4,4'-trichloro-21-hydroxydiphenyl ether (triclosan), and a synthetic anionic linear polymeric polycarboxylate having a molecular weight of about 1,000 to about 1,000,000.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
128 words
An oral composition comprising in an orally acceptable vehicle, a water-humectant phase, said water and humectant comprising at least about 10% by weight of said oral composition, an effective antiplaque amount of a substantially water insoluble noncationic halogenated diphenyl ether antibacterial agent and about 0.0005-4% by weight of a synthetic anionic polymeric polycarboxylate having a molecular weight of about 1,000 to about 1,000,000, wherein said water-humectant phase includes a solubilizing agent which prevents precipitation of said antibacterial agent upon dilution with saliva during use in the oral cavity and which solubilizes said substantially water-insoluble non-cationic halogenated diphenyl ether antibacterial agent and is present in amount sufficient to dissolve said antibacterial agent and prevent precipitation of said antibacterial agent upon dilution with saliva during use in the oral cavity.
Claim 2
Dependent Claim
128 words
An oral composition comprising in an orally acceptable vehicle, a water-humectant phase, said water and humectant comprising at least about 10% by weight of said oral composition, an effective antiplaque amount of a substantially water insoluble noncationic halogenated diphenyl ether antibacterial agent and about 0.0005-4% by weight of a synthetic anionic polymeric polycarboxylate having a molecular weight of about 1,000 to about 1,000,000, wherein said water-humectant phase includes a solubilizing agent which prevents precipitation of said antibacterial agent upon dilution with saliva during use in the oral cavity and which solubilizes said substantially water-insoluble non-cationic halogenated diphenyl ether antibacterial agent and is present in amount sufficient to dissolve said antibacterial agent and prevent precipitation of said antibacterial agent upon dilution with saliva during use in the oral cavity.
