Abstract: The present disclosure generally relates to a multicarboxylate, such as an alkyl alkoxy dicarboxylate a method of making the multicarboxylate, and methods to use the multicarboxylate. A specific embodiment of the disclosure is a compound comprising the chemical formula: R1-R2-R3, wherein R1 comprises a branched or unbranched, saturated or unsaturated, cyclic or non-cyclic, hydrophobic carbon chain having 7-150 carbon atoms; an oxygen atom linking R1 and R2; R2 comprises an alkoxylated chain comprising ethylene oxide, propylene oxide, butylene oxide, or a combination thereof; and R3 comprises a branched or unbranched hydrocarbon chain comprising 2-12 carbon atoms and 2-5 —COOH or —COOM groups wherein M is a monovalent, divalent, or trivalent cation. The composition has a variety of uses but in some embodiments may be used in enhanced oil recovery processes.
