  • Patent number: 5728756
    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.

  • Patent number: 5686064
    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.

  • Patent number: 5505933
    Abstract: An oral composition, such as a toothpaste, includes an anti-tartar proportion of a polyphosphate anti-tartar agent (preferably with synthetic anionic polymeric polycarboxylate or equivalent, and fluoride) and a desensitizing proportion of a tooth pain inhibiting potassium salt which passes through exposed dentin tubules to tooth nerves or neurons, which salt can be potassium nitrate, potassium citrate or potassium oxalate, so that it helps to prevent tartar from forming on the teeth and also lessens any pain experienced by persons contacting their sensitive teeth with the oral composition. Preferably the oral composition is a desensitizing anti-tartar toothpaste or gel which, when the teeth are brushed with it, aids in removal of at least some tartar and prevents its reappearance, and at the same time diminishes any tooth pain that the brusher would otherwise experience due to such brushing.

  • Patent number: 5496540
    Abstract: An oral composition, such as a paste or gel dentifrice or a liquid mouthwash, containing a substantially water insoluble non-cationic antibacterial agent, such as triclosan, which, when used to clean the teeth or rinse the mouth, acts to decrease plaque on the teeth, is packaged in a dispensing container which includes a solid polymeric material, such as polyfluoroethylene, which is compatible with the antibacterial agent so that excessive loss of anti-plaque activity of such agent on storage is avoided. Alternatively, various other polymers may be employed as container parts, which normally would cause excessive losses of anti-plaque action of the antibacterial agent in the composition, but such action is countered by the presence of a stabilizer, such as a terpene, e.g., limonene, in the oral composition formula.

  • Patent number: 5472685
    Abstract: An antiplaque oral composition, such as a toothpaste, gel dentifrice, tooth powder, mouthrinse or mouthwash, tooth hardener, anticalculus composition, gum or lozenge, comprises triclosan as an antiplaque component, the antiplaque action of which is unexpectedly and beneficially increased by the presence in the oral composition of a phenolic flavoring agent, such as eucalpytol, thymol, methyl salicylate, menthol, phenol, halogenated derivatives thereof, and mixtures thereof. Preferred such compositions are toothpastes, gel dentifrices and mouthrinses or mouthwashes. Also within the invention are processes of repeatedly applying such antiplaque oral compositions to the teeth to obtain the antiplaque benefits mentioned.

  • Patent number: 5472684
    Abstract: A composition comprising thymol and eugenol, and optionally a sesquiterpene alcohol, such as, farnesol or has been found to have plaque and gingivitis effect. Flavoring agents may be included to provide an organoleptically acceptable oral product. Australian Tea Tree oil, sage oil and eucalyptol were found to enhance the antiplaque and antigingivitis activity of mouthrinses formulated from these compositions.These compositions exhibit an antibacterial effect vs. A. viscosus of about 25 MIC or less.
