ABSTRACT:
A very effective composition for inhibiting vapor losses of stored hydrocarbons comprises a mixture of a fluorosurfactant, a silicone surfactant, a polyglycol, and a glycol ether. Indeed, a method for retarding evaporation of volatile hydrocarbons from a body of liquid hydrocarbon material is provided by forming a thin film of these compositions on the surface of the body of liquid hydrocarbons.
