  • Moth and insect repellant
    Patent number: 6251431
    Abstract: A biodegradable insect repellant that breaks down in the presence of water to minimize solid waste, comprising a water soluble substrate substantially comprising foamed vegetable starch, and cedar oil carried in the substrate. The substrate is preferably made of corn and or potato starch. The cedar oil may be from about 0.01 to about 10 times the weight of the substrate. A coloring agent may optionally be provided in the cedar oil to impart color to the insect repellant. Because the substrate is made from a water soluble starch, it dissolves in water leaving little or no solid waste.
