Abstract

An additive composition for a hydraulic fluid, or a heat transfer fluid, comprises one or more phosphate esters derived from the esterification of phosphoric acid and one or more monomer glycols containing up to 18 carbon atoms, or combinations thereof. In addition, the additive composition may comprise one or more corrosion inhibitors selected from the group consisting of dicarboxylic acids, alkanolamines or combinations thereof; one or more antioxidants including selected from the group consisting of one or more organosulfur compounds, one or inorganic oxyanion salts or combinations thereof; and, one or more surfactants.
