Abstract: Disclosed is a composition for delivering an oral care substance to the oral cavity, comprising: (a) an organosiloxane resin; (b) a volatile carrier capable of solubilizing the organosiloxane resin; (c) a rheology modifier; and (d) at least one oral care substance. The present invention is also directed to such compositions comprising: (a) an organosiloxane resin; (b) a fluid diorganopolysiloxane polymer; (c) a volatile carrier capable of solubilizing the organosiloxane resin and the fluid diorganopolysiloxane polymer; (d) a rheology modifier; and (e) at least one oral care substance. Further disclosed is a method of using these compositions.

Abstract: The present invention relates to oral compositions comprising a stannous ion source, a fluoride ion source, and a polymeric mineral surface active agent that binds stannous, said compositions providing adequate therapeutic efficacy with minimal side effects of tooth staining and astringency. The composition simultaneously provides reduction and control of supragingival calculus. The present oral care compositions may be formulated as single phase or dual phase compositions. The present invention also provides a method for effective delivery of stannous-containing compositions with minimal side effects of tooth staining or astringency and with effective tartar control by administering to a subject a stable dentifrice composition comprising a clinically effective amount of stannous fluoride and/or other stannous salts in combination with a fluoride ion source and a polymeric mineral surface active agent, preferably a phosphate- or phosphonate-containing polymer.

Abstract: The present invention relates to dual phase oral compositions providing effective antimicobial activity for reducing plaque and gingivitis. One of the phases of the dual phase composition will contain stannous. The stannous phase comprises a stannous ion source, a fluoride ion source, and a gluconate salt. The stannous phase is essentially free of either an abrasive polishing material or chloride ions. The stannous phase containing phase inhibits the formation of a stannous chloro gluconate complex. The present invention also provides a method for effective delivery of stannous-containing compositions.

Abstract: According to the present invention there is provided a visually clear, dentrifice gel comprising; a) sufficient tetrasodium pyrophosphate to provide from 0.2% to 5% pyrophosphate anion; b) a silica dental abrasive having a refractive index of from 1.445 to 1.47; c) from 0.7% to 3% sodium alkyl sulphate; and d) an aqueous liquid carrier. The gel has excellent clarity, high anticalculus efficiency and good foaming. According to a further aspect of the invention there is provided a process for making a clear dentifrice gel comprising the step of adding anhydrous tetrasodium pyrophosphate to an aqueous carrier, the gel comprising: a) a silica dental abrasive having a refractive index of from 1.445 to 1.47; and b) an aqueous liquid carrier comprising less than 27% total water. The use of anhydrous tetrasodium pyrophosphate allows greater formulation flexibility at the processing stage by freeing up water for the dissolution and/or hydration of other dentrifice components.

Abstract: Disclosed are oral compositions comprising one or more linear polyphosphates having an average chain length of about 4 or more, sodium monofluorophosphate, a buffering agent, an abrasive polishing material containing less than 23% calcium, and one or more aqueous carriers, wherein the oral composition has a total water content of from about 5% to about 20%.

Abstract: Disclosed are methods for reducing the astringency of dentifrice composition containing stannous comprising administering to the subject a dentifrice composition comprising stannous. The dentifrice composition comprises stannous ions, poloxamer, and aqueous carriers. The efficacy of this dentifrice composition containing stannous will not be reduced by the poloxamer. The dentifrice composition may also contain a polyphosphate as long as the water content is limited and the stannous ion is not provided from stannous fluoride. The polyphosphate will also not reduce the efficacy of the stannous. Alternatively, the dentifrice composition may be a dual phase composition. The first dentifrice composition will contain a polyphosphate having an average chain length of about 4 or more and have a limited water content while the second dentifrice composition will contain stannous ions. In the dual phase composition, the poloxamer will be present in the first or second dentifrice compositions or both compositions.
