Abstract
A fragrant potpourri gel mixture is disclosed for dispensing fragrance to the air from a container, with the mixture lacking free liquids and being pourable into or out of the container. The fragrant potpourri gel mixture is prepared by providing an aqueous-based liquid, adding a bittering agent, and combining a coloring agent to form an aqueous-based mixture. An oil-based compound having a volatile fragrance oil component is added to the aqueous-based liquid. An absorbent polymer is mixed in by agitation or stirring to absorb the aqueous-based liquid within a gel mixture and to emulsify the oil-based fragrance component throughout to form a heterogeneous gel mixture having a plurality of micro-droplets of oil fragrance components and air pockets suspended therein. The heterogeneous gel mixture is prepared at room temperatures without heating. The volatile fragrance components of the micro-droplets volatilize from the surfaces of the micro-droplets when exposed to the air. To improve the release of volatile fragrance component, a petroleum solvent is mixed with the oil-based compound added to the aqueous-based liquid mixture. Also disclosed is a method of making a fragrant potpourr…
