Abstract
The present invention is directed to surfactants with small hydrophobes, which are of non-conventional hydrophobe size. The surfactants of the present invention utilize a small hydrophobic moiety with a polyalkoxylate chain comprising PO, BO and/or EO groups, with optional ionic groups, such as anionic, cationic and zwitterionic, to achieve the desired hydrophilic-lipophilic balance (HLB). The present invention is further directed to formulations comprising the surfactants of the invention, and methods of using the surfactants of the invention, including in enhanced oil recovery applications.
