Title: Air freshener

Abstract: A biodegradable air freshener that breaks down in the presence of water to minimize solid waste, including a water soluble substrate including foamed vegetable starch and a liquid fragrance carried in the substrate. The liquid fragrance may be from about 0.01 to about 10 times the weight of the substrate. A coloring agent may optionally be provided in the liquid fragrance to impart color to the air freshener. Because the substrate is made from a water soluble starch, it dissolves in water leaving little or no solid waste.
