Abstract
A system for delivering a chemical agent in the form of a foam, which in its preferred embodiment involves the use of a propellantless dispenser to deliver a formulation containing both an anionic surface active agent such as sodium lauryl sulfate as a foaming agent and hydrogen peroxide as a disinfecting chemical agent.
Claims18
A system for delivering a chemical agent comprising
- a medicament in the form of an aerated foam, the system comprising a propellantless dispenser containing a foamable dental formulation comprising the chemical agent in the form of a solution or stable suspension and an aqueous solution of an anionic surface active agent as a foaming agent,
- said foaming agent being selected from the group consisting of cocomonoglyceride sulfonate, sodium lauryl sarcosinate, sodium dodecylbenzene sulfonate, dioctyl sodium sulfosuccinate, sodium lauryl sulfoacetate, sulfolaurate, 2-hydroxylalkyl sulfate, sodium lauryl sulfate, and the mixtures thereof.
A system for delivering a chemical agent comprising
- a medicament in the form of an aerated foam, the system comprising a propellantless dispenser containing a foamable dental formulation comprising the chemical agent in the form of a solution or stable suspension and an aqueous solution of an anionic surface active agent as a foaming agent.
A system for delivering a chemical agent comprising
- a medicament in the form of an aerated foam, the system comprising a propellantless dispenser containing a foamable dental formulation comprising the chemical agent in the form of a solution or stable suspension and an aqueous solution of an anionic surface active agent as a foaming agent, and
- said foamable formulation being a disinfecting solution.
A kit for delivering a chemical agent comprising
- a medicament in the form of an aerated foam, the kit comprising a propellantless dispenser and a separately packaged volume of a foamable dental formulation comprising the chemical agent in the form of a solution or stable suspension and an aqueous solution of an anionic surface active agent as a foaming agent,
- said foaming agent being selected from the group consisting of cocomonoglyceride sulfonate, sodium lauryl sarcosinate, sodium dodecylbenzene sulfonate, dioctyl sodium sulfosuccinate, sodium lauryl sulfoacetate, sulfolaurate, 2-hydroxyalkyl sulfate, sodium lauryl sulfate, and mixtures thereof.
A method for delivering a chemical agent comprising a medicament in the form of an aerated foam, comprising the steps of
- providing a delivery system comprising a propellantless dispenser containing a foamable dental formulation comprising the chemical agent in the form of a solution or stable suspension and an aqueous solution of an anionic surface active agent as a foaming agent,
- said foaming agent being selected from the group consisting of cocomonoglyceride sulfonate, sodium lauryl sarcosinate, sodium dodecylbenzene sulfonate, dioctyl sodium sulfosuccinate, sodium lauryl sulfoacetate, sulfolaurate, 2-hydroxyalkyl sulfate, sodium lauryl sulfate, and mixtures thereof.
A system for delivering a chemical agent comprising a medicament in the form of an aerated foam, the system comprising a propellantless dispenser for dispensing aerated foams, said dispenser containing a foamable aqueous dental formulation comprising the medicament and an anionic surface active agent as a foaming agent.
A system for delivering a chemical agent comprising a medicament in the form of a foam, the system comprising a propellantless dispenser containing a foamable formulation comprising the chemical agent in the form of a solution or stable suspension and an aqueous solution of an anionic surface active agent as a foaming agent;
- wherein said chemical agent is hydrogen peroxide;
- wherein said surface active agent is sodium lauryl sulfate;
- wherein said formulation is a dental formulation;
- and optionally containing essential oils and aloe.
