This invention relates to oral care compositions comprising zinc phosphate, a first source of stannous (e.g., stannous fluoride); and a second source of stannous, wherein the second source of stannous comprises stannous pyrophosphate, as well as to methods of using and of making these compositions.

Oral care compositions and methods of use

This invention relates to oral care compositions comprising guanidine, zinc citrate and zinc oxide, and a fluoride source, as well as to methods of using and of making these compositions.

Disclosed herein is a composition comprising a pH-sensitive microcapsule comprising (1) a shell wall comprising at least one polymer chosen from cellulose derivatives and acrylate derivatives, and at least one structuring agent chosen from shellac, ethyl cellulose, and fumed silica, and (2) at least one functional ingredient encapsulated inside the shell wall; and a carrier having a pH of less than about 7. Further disclosed herein are methods of making a composition comprising a pH-sensitive microcapsule.

Compositions comprising pH-sensitive microcapsules

This invention relates to oral care compositions comprising a zinc source comprising zinc oxide and zinc citrate; a stannous source comprising stannous pyrophosphate; a fluoride ion source comprising sodium fluoride; and an organic buffer, as well as to methods of using and of making these compositions.

Disclosed herein are improved methods for the synthesis of stannous pyrophosphate, as well as improved methods for the manufacture of oral care compositions comprising stannous pyrophosphate.

Methods for synthesizing stannous pyrophosphate

This invention relates to oral care compositions comprising zingerone, bisabolol, a stannous ion source, zinc oxide, and zinc citrate, as well as to methods of using and of making these compositions.

This invention relates to oral care compositions comprising a basic amino acid in free or salt from (e.g., free form arginine); zinc oxide and zinc citrate; and a fluoride source comprising stannous fluoride.
