Abstract
An aqueous-based gel air-treating composition comprising a gel base including a gel-forming agent and a gaseous component in an amount effective to provide a bulk density of said composition of from about 0.5 to about 0.9 g/cc, the gaseous component being present in within the composition as substantially homogeneously dispersed bubbles having a diameter of less than about 3000 microns, the composition being obtained by preparing said gel base, introducing the gaseous component into said gel base with sufficient mixing energy to obtain a foamed gel, and allowing the foamed gel to cool below its glass transition temperature.
