ABSTRACT:
An insect repellent including a liquid system containing DEET and a fragrance oil which acts as a carrier for dispersing DEET vapor into the atmosphere upon evaporation of the fragrance oil. In one embodiment of the invention, the liquid system is contained within a solid thermoplastic system which can be formed as pellets for fabricating utilitarian products, e.g., wristbands and tablecloths. In another embodiment of the invention, the liquid system is contained within the wax of a candle which can be burned to emit DEET vapor into the atmosphere. In a third embodiment, the liquid system can be mixed with alcohol, with or without water, and dispersed by an air-wick to repel insects. In a fourth embodiment, towelettes can be soaked in the liquid system for later use as applicators of the liquid system to areas of the skin from which Deet vapor can be released into the atmosphere for effectively repelling insects from around the entire body.
