Abstract
A method for preparing an antimicrobial alcoholic foam composition by combining two or more pre-mix compositions. A first pre-mix composition is primarily alcoholic comprises an alcohol, an acidic component, and a waxy component. A second pre-mix composition is primarily aqueous comprises water and a carbonate. An antimicrobial alcoholic foam composition that does not require added air or aerosol propellant is also provided.
Claims42
A method of preparing an antimicrobial alcoholic foam composition, the method comprising the steps of:
- providing a dispenser having a first reservoir containing a first liquid pre-mix that is an aqueous pre-mix, a second reservoir containing a second liquid pre-mix that is an alcoholic pre-mix;
- dispensing an aliquot of said aqueous pre-mix, wherein said aqueous pre-mix comprises a carbonate and water;
- dispensing an aliquot of said alcoholic pre-mix, wherein said alcoholic pre-mix comprises at least 50 wt. % of a C1-6 alcohol, based upon the total weight of the alcoholic pre-mix, a waxy component, and an acidic component;
- commingling said aliquot of said aqueous pre-mix and said aliquot of said alcoholic pre-mix, whereupon said aliquots of said aqueous pre-mix and said alcoholic pre-mix chemically react and generate an antimicrobial alcoholic foam.
A method of preparing a non-aerosol antimicrobial alcoholic foam composition, the method comprising the steps of:
- providing a dispenser having a first reservoir containing a first liquid pre-mix that is an aqueous pre-mix, a second reservoir containing a second liquid pre-mix that is an alcoholic pre-mix;
- dispensing an aliquot of said aqueous pre-mix, wherein said aqueous pre-mix comprises a carbonate and water;
- dispensing an aliquot of said alcoholic pre-mix, wherein said alcoholic pre-mix comprises at least 50 wt. % of a C1-6 alcohol, based upon the total weight of the alcoholic pre-mix, a waxy component, and an acidic component;
- commingling said aliquot of said aqueous pre-mix and said aliquot of said alcoholic pre-mix, whereupon said aliquots of said aqueous pre-mix and said alcoholic pre-mix chemically react and generate an antimicrobial alcoholic foam;
- wherein the foam expands upon the reaction of the acid and the carbonate to a final volume that is 1.5 to 5 times the combined liquid volume of the aqueous pre-mix and the alcoholic pre-mix.
