Abstract
Chemical compounds that are N-lauroyl amino acids containing a polyethylene oxide segment were found to have oil-releasing activity. Solutions containing these compounds may be introduced into oil reservoirs or onto oil-contaminated surface sites to release oil from oil-coated surfaces. The released oil may be recovered for further processing or waste disposal.
