Abstract: Provided herein are novel surfactant compositions and methods having application in a variety of fields including enhanced oil recovery, the cleaning industry as well as groundwater remediation. The surfactant compositions are based on lignin bio-oil with a phenol hydroxyl group as the main functional group. The compositions include carboxylic surfactant s and mixed hydrophilic and hydrophobic surfactant structures, which can be used for the recovery of crude oil compositions from challenging reservoirs.
