ORAL CARE COMPOSITIONS

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.
