    Patent number: 6326187
    Abstract: Soil, which is contaminated by one or more hydrophobic organic chemicals, can be cleaned or remediated using an aqueous composition with a surfactant prepared by reacting an alkenylsuccinic anhydride or acid with an amine acid or salt of an amine acid. The surfactant allows at least a portion of the hydrophobic organic chemical to be removed from the soil by becoming associated with the aqueous composition, which is then separated from the soil.
