  • Patent number: 5503823
    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: 5476598
    Abstract: The stability and softening performance of amidoamine fabric softeners, such as bis(hydrogenated tallow amidoethyl)-2-hydroxyethyl amine) is improved by protonating the amine with a neutralizing inorganic or organic acid and incorporating certain stabilizing emulsifiers, such as, N,N',N'-tris(2-hydroxyethyl)-N-tallow-1,3-diaminopropane, dimethylhydrogenated tallow amine, methyl dihydrogenated tallow amine, and oleic imidazoline). Mixtures of bis(hydrogenated tallow amidoethyl)-2-hydroxyethyl amine and bis(tallow amidoethyl)-2-hydroxyethyl amine also provide improved softening and form stable aqueous dispersions.

  • 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.
