Abstract:
An oral care composition having a first phase of clinically efficacious 2,4,4'-trichloro 2'-hydroxydiphenyl ether admixed in a first orally acceptable aqueous vehicle, and a second phase having a stannous salt (such as stannous fluoride) admixed in a second orally acceptable aqueous vehicle. The second phase has no less than 10 molar percent of soluble stannous ion respective to a mathematical sum of moles of the soluble stannous ion and moles of the stannous salt in the second phase. In one embodiment, the two phases are provided in a dual-tube toothpaste oral care kit.
Abstract:
A stable and efficacious antiplaque, anticalculus, and antigingivitis oral composition is provided having an antibacterial ingredient comprising one or more active compounds found in an extract of magnolia combined with an anticalculus system comprising tetrasodium pyrophosphate (TSPP) about 1 to about 2.5% and sodium tripolyphosphate (STPP) about 1 to about 10%. The oral composition can be in the form of a mouth rinse or dentifrice, including toothpaste, gels, powders, as well as confectionaries, lozenges, and the like. Methods of making and using the oral composition are also provided.
Abstract:
An anti-staining, antibacterial dentifrice comprises an anti-staining effective amount of an orally acceptable polymer or copolymer that comprises a plurality of monomeric groups of formula (I) wherein (a) one of A and A' is hydrogen and the other is a moiety (X) n (R) m , (b) n in individual such moieties is independently 0 or 1, (c) linking groups X if present independently comprise an oxygen, sulfur, nitrogen, phosphorus or silicon atom, (d) where n is 0, m is 1, and where n is 1, m is independently an integer from 1 to 3 as determined by X, (e) terminal groups R are independently hydrogen or C 1-18 organic radicals, and (f) M and M' are independently selected from hydrogen, alkali metal and ammonium; said polymer or copolymer having an average molecular weight of at least about 1,000. The dentifrice further comprises an antibacterial effective amount of an orally acceptable halogenated diphenylether antibacterial agent, and an antibacterial enhancing effective amount of an orally acceptable polyvinylmethylether/maleic anhydride copolymer.
Abstract:
A method for whitening a dental surface comprises nonsimultaneously applying a whitening composition to the surface, the whitening composition comprising at least one orally acceptable peroxy compound, and directing a volume of up to about 2.5 ml of an atomized activating composition on to the surface, wherein the activating composition comprises, in the volume so directed, a peroxy compound activating effective amount of at least one orally acceptable basifying agent, and wherein applying the whitening composition and directing the activating composition are separated by an interval not greater than a peroxy compound activating effective interval. The atomized composition can be directed on to the dental surface before or after application of the whitening composition.
Abstract:
A stable, nonaqueous liquid tooth whitening composition comprised of an anhydrous peroxide compound dispersed in an orally acceptable mixture of an anhydrous hydrophilic polymer and an adhesion enhancer which composition when applied topically to tooth surfaces forms an adherent layer containing the peroxide compound which peroxide compound is thereafter is released from the layer to effect tooth whitening.
Abstract:
A striped dentifrice stable color bleeding, wherein at least one component contains a colorant entrained in the matrix of substantially non-fracturable, partially cross-linked melamine-urea-formaldehyde condensation polymer particles, whereby on storage the colorant does not bleed any color into any other dentifrice component. The dentifrice may also contain a formaldehyde scavenger to bind-up any formaldehyde released from the particles.
Abstract:
A method is disclosed for the coextrusion in controlled amounts of at least two dentifrice components stored and physically segregated in a multicompartmented collapsible dispenser provided with a partition which divides the interior volume of the container into separate compartments, the partition being moveable in response to a pressure differential developed thereacross upon the application of Compressive Force to the sidewalls, the individuals dentifrice components containing ingredients which interact when mixed, the dispenser sidewalls being formed of a resilient plastic material which is deflected upon the application thereto of a Deflective Force of about 1.0 or greater pounds, the dentifrice compnents being formulated to be equally extrudible at substantially equivalent compressive forces. When the dispenser sidewalls are compressed, there is extruded a single-banded unmixed multilayer stream of the components containing the reactive ingredients at ratios predetermined to provide optimum levels for interaction between the reacted ingredients when the extruded components are mixed in the oral cavity.
Abstract:
An aqueous oral care composition containing a stannous ion releasing compound and a combination of a pyrophosphate salt, and an organic acid compound, the combination being present in the composition in an amount sufficient to effectively stabilize the stannous ion concentration.
Abstract:
An oral care composition comprising zinc phosphate, stannous fluoride, an anionic polymer, and a basic amino acid, as well as methods of using the same.
