Abstract: An oral care (toothpaste) amalgam composition has first and second aqueous phases. The first phase has a measured pH of from about 7 to about 9 and contains 2,4,4?-trichloro-2?-hydroxydiphenyl ether and a methylvinyl ether-maleic anhydride copolymer antibacterial-enhancing agent for the ether. The second aqueous phase has a measured pH of from about 3.5 to about 6.5 and contains hydrogen peroxide and an antioxidant for the hydrogen peroxide. Sodium fluoride, silica, and sodium lauryl sulfate are optionally independently present in at least one of the first and second phases.

Abstract: It has been found that a mouthrinse comprising CPC and zinc ions is a very effective mouthrinse. It has an antibacterial effect that removes odor creating bacteria from the oral cavity. The CPC and zinc ions preferably are used in combination with an ionone terpene such as alpha ionone or a beta ionone.

Abstract: A dual component chlorhexidine dentifrice composition of improved shelf stability in which the first component is a gel containing a bis-biguanide antibacterial agent in which the gel vehicle is thickened with a cellulose polymer and the second component is a paste containing a silica abrasive wherein the bis-biguanide antibacterial agent provides undiminished antiplaque and antigingivitis effect with reduced staining when the physically separated components are combined and mixed upon application to dental tissue.

Abstract: An oral antiplaque composition comprising an orally acceptable vehicle and an effective antiplaque amount of silver zeolite and a stabilizing amount of a chloride salt.

Abstract: An antiplaque and anticalculus oral composition containing an antimicrobial agent such as chlorohexidine or triclosan and an azacycloalkane-2,2-diphosphonic compound.

Abstract: A process which inhibits bacteria and caries comprising the application of an oral composition containing a substantially water insoluble noncationic antimicrobial agent, such as triclosan, xylitol, and sodium lauryl sulfate as the surfactant and dispersant for the water insoluble noncationic antimicrobial agent.

Abstract: A stable antibacterial oral composition containing a hydrogenated lupulone and an anionic surfactant.

Abstract: A high foaming oral composition comprising in an orally acceptable vehicle, an effective antiplaque, antibacterial compound, and at least about 2% by weight of a mixed anionic/nonionic surfactant system in a weight ratio of about 7:1 to 2:1, respectively, which ratios are effective to increase the uptake of the antibacterial compound to dental tissue so as to enhance the therapeutic efficacy of the administered antibacterial compound.

Abstract: The invention provides an antibacterial oral composition containing an antibacterial compound, a monoalkyl phosphate compound and another anionic surfactant; whereby, the antibacterial effect on dental tissue is substantially increased due to the combined presence of the monoalkyl phosphate compound and the other anionic surfactant in a given weight ratio.

Abstract: A method for enhancing the antiplaque efficacy of an antibacterial dentifrice, comprising preparing a multicomponent dentifrice composition having a first dentifrice component containing an antibacterial agent and manganese coordination complex compound, and a second dentifrice component containing a peroxide compound; maintaining the first and second dentifrice components separately prior to use; combining the dentifrice components and applying the two components to the teeth and periodontium, whereby the dentifrice provides enhanced inhibition of plaque growth.

Abstract: An oral composition dentifrice comprising an orally acceptable vehicle, about 5-30% by weight of a siliceous polishing agent, about 0.25-0.35% by weight of a substantially water-insoluble noncationic antibacterial antiplaque agent, such as 2,4,4'-trichloro-2'-hydroxydiphenyl ether (triclosan) and an antibacterial-enhancing agent which enhances the delivery of said antibacterial agent to, and retention thereof on, oral surfaces.

Abstract: An oral composition dentifrice comprising an orally acceptable vehicle, about 5-30% by weight of a siliceous polishing agent, a substantially water-insoluble noncationic antibacterial antiplaque agent, such as 2,4,4'-trichloro-2'-hydroxydiphenyl ether (triclosan), and an antibacterial-enhancing agent which enhances the delivery of said antibacterial agent to, and retention thereof on, oral surfaces, wherein said antiplaque agent is substantially completely dissolved in saliva present during tooth and gum cleaning in a solubilizing agent therefor. The solubilizing agent may be a humectant polyol such as propylene glycol, dipropylene glycol and hexylene glycol; a cellosolve such as methy cellosolve and ethyl cellosolve: a vegetable oil or wax containing at least about 12 carbon atoms in a straight chain such as olive oil, castor oil and petrolatum; or an ester such as ethyl acetate, amyl acetate, glyceryl tristearate and benzyl benzoate.

Abstract: An oral composition comprising in an orally acceptable vehicle, an effective antiplaque amount of an halogenated diphenyl ether or phenolic antibacterial compound, and an amount of an mixed anionic/nonionic surfactant system at weight ratios of about 14:1 to 9:1 which ratios are effective to increase the uptake of the antibacterial compound to dental tissue so as to enhance the therapeutic efficacy of the administered antibacterial compound.

Abstract: An oral composition such as a dentifrice, mouthwash, lozenge or chewing gum containing a polyphosphate anticalculus agent, such as tetraalkali metal pyrophosphate and antibacterial antiplaque agent compatible therewith. The antiplaque agent is a substantially water-insoluble noncationic antibacterial agent such as 2,4,4'-trichloro-2'-hydroxydiphenyl ether (Triclosan). Antiplaque effectiveness is optimized by the presence of an antibacterial-enhancing agent which enhances delivery of said antibacterial agent to, and retention thereof on, oral surfaces.

Abstract: The invention provides an antibacterial oral composition containing an antibacterial compound such as Triclosan and a monoalkyl phosphate compound whereby the uptake and retention of the antibacterial compound on dental tissue is substantially increased due to the presence of the monoalkyl phosphate compound.
