The present invention provides a liquid evaporation inhibitor which is suitable for use in high temperature applications; e.g., above 70 DEG C. The evaporation inhibitor liquid comprises a mixture of an alkane, a non-volatile oil, preferably a vegetable oil and a surfactant. The alkane is present in the mixture in an amount sufficient to provide a density which promotes floating on an aqueous medium and to cover an aqueous medium. The non-volatile oil is present in the mixture in an amount sufficient to inhibit evaporation of the mixture at temperatures above 70 DEG C. The surfactant is present in the mixture in an amount sufficient to maximize the contact surface area between the evaporation inhibitor liquid and the aqueous medium.
