A release agent for concrete includes water, a vegetable oil or animal derived oil ester and a polymeric thickener. The composition can either be a direct release agent wherein the composition is a water-in-oil emulsion or an indirect release agent which is an oil-in-water emulsion. The indirect agent may further include vegetable oil wetting agents and biocides. The release agent does not include typical surfactants such as anionic surfactants, cationic surfactants, zwitterionic surfactants, nonionic surfactants, or amphoteric surfactants.
