Abstract
Insect-repelling compositions comprise from about 0.001% to about 10% by weight of plant essential oils. The balance of the composition to 100% by weight includes deionized water, vanillin powder, isopropanol, glycerin, an emulsifier (such as polyglycerol oleate and/or sodium lauryl sulfate), and an aqueous chitosan formulation. The chitosan formulation comprises ≤8% volume of chitosan and ≤8% volume of acetic acid or vinegar.
