摘要： An improved soil release polymer composition comprising a soil release polymer and a long chain nonionic alkoxylate surfactant and/or amphoteric that is able to generate very low critical micelle concentration values in water. Preferably, the soil release composition is incorporated in a detergent system such as a commercial laundry detergent which comprises a second anionic, nonionic or cationic surfactant and mixtures thereof. By lowering the cmc values of the detergent wash water to very low levels, the surfactant greatly enhances the performance of the soil release polymer.

摘要： Compositions are disclosed comprising a conventional surfactant, a cationic or amphoteric gemini surfactant and a polymeric soil release agent. The conventional surfactant comprises a hydrophilic group and a hydrophobic group. The gemini surfactant comprises two surfactant moieties attached to each other by a spacer moiety. Each surfactant moiety having at least one hydrophilic group and at least one hydrophobic group. Novel trimeric and tetrameric cationic gemini surfactants are also disclosed along with their use in combination with soil release polymer compositions that exhibit superior cleaning efficacies when incorporated in laundry and other cleaning detergent systems. Novel surfactant/soil release polymer compositions are also disclosed employing known cationic gemini surfactants. The polymeric soil release agent can be any conventional polymeric soil release agent, but preferably comprising PET—POET copolymer. The compositions are useful as surfactant additive packages, detergents and fabric softeners.

摘要： There is a method for enhancing the recovery of oil from a reservoir. The method has the step of a) introducing a flooding fluid into the reservoir and b) extracting the oil through a wellbore at a location different than the point of introduction of the flooding fluid into the reservoir. The flooding fluid has water and an amount of one or more non-polymeric viscoelastic surfactants sufficient to provide an interfacial surface tension of about 1 mNm or less and a viscosity of about 10 cps or more. The one or more surfactants is selected from the group of one or more cationic surfactants, one or more zwitterionic surfactants, one or more amphoteric surfactants, one or more anionic surfactants, and combinations thereof.

摘要： Viscoelastic surfactant based aqueous fluid systems useful as thickening agents in various applications, e.g. to suspend particles produced during the excavation of geologic formations. The surfactants are zwitterionic/amphoteric surfactants such as dihydroxyl alkyl glycinate, alkyl ampho acetate or propionate, alkyl betaine, alkyl amidopropyl betaine and alkylimino mono- or di-propionates derived from certain waxes, fats and oils. The thickening agent is used in conjunction with an inorganic water-soluble salt or organic additive such as phthalic acid, salicylic acid or their salts.
