This application provides, among other things, oral care compositions where the addition of a stabilizing amount of a nonionic gelling and thickening agent, (e.g., hydroxyethyl cellulose (HEC)), to formulations comprising a bisbiguanide (e.g., chlorhexidine (CHX)) agent allows for proper structure and consistency to the formulation and to allow it to be used as a gel or a toothpaste to facility delivery of chlorhexidine, among other actives, to the teeth or gums.

This application provides, among other things, oral care compositions where the addition of a stabilizing amount of a nonionic gelling and thickening agent, (e.g., hydroxyethyl cellulose (HEC)) and an effective amount of a zwitterionic surfactant (e.g., a betaine zwitterionic surfactant) (e.g., cocamidopropyl betaine), to formulations comprising a bisbiguanide (e.g., chlorhexidine (CHX)) agent, and optionally an effective amount of abrasive silica, allows for proper structure and consistency to the formulation and to allow it to be used as a gel or a toothpaste to facility delivery of chlorhexidine, among other actives, to the teeth or gums with acceptable stability and foaming.

The antimicrobial composition of the present invention comprises a cationic active ingredient, a foam boosting surfactant, a foam boosting copolymer, a foam stabilizer, and a chelating agent. The present antimicrobial compositions are free of the antimicrobial agent triclosan (i.e., 2,4,4′-trichloro-2′hydroxy-diphenylether), have rapid cidal activity, provide stable copious foam and exhibit enhanced tissue (e.g. skin) compatibility as defined by an in vitro whole toxicology assessment method.

A reloadable microcapsule contains a microcapsule core and a microcapsule wall encapsulating the microcapsule core. The microcapsule core contains a hydrophobic core solvent and a hydrophilic core solvent, and the microcapsule wall, formed of an encapsulating polymer, is permeable to the hydrophilic core solvent. Also disclosed are methods of preparing the reloadable microcapsule and consumer products having the microcapsules.
