Zusammenfassung:	The present disclosure relates to the use of a multicarboxylate, such as an alkyl alkoxy dicarboxylate, in enhanced oil recovery processes. Embodiments relate to an aqueous stream and the use thereof. The aqueous stream includes a compound having the chemical formula: R1-R2-R3, wherein R1 includes a branched or unbranched, saturated or unsaturated, cyclic or non-cyclic, hydrophobic carbon chain having an oxygen atom linking R1 and R2; R2 includes an alkoxylated chain comprising ethylene oxide, propylene oxide, butylene oxide, or a combination thereof; and R3 includes a branched or unbranched hydrocarbon chain and 2-5 -COOH or -COOM groups wherein M is a monovalent, divalent, or trivalent cation. R3 includes 2-12 carbon atoms.
