  • Gemini surfactants form a special class of surfactant. These surfactants have the general formula: A-G-A 1 and get their name because they comprise two surfactant moieties (A,A 1 ) joined by a spacer (G), wherein each surfactant moiety (A,A, 1 ) has a hydrophilic group and a hydrophobic group. Generally, the two surfactant moieties (A,A 1 ) are twins, but they can be different.
  • the gemini surfactants are advantageous because they have low critical micelle concentrations (cmc) and, thus, lower the cmc of solutions containing both a gemini surfactant and a conventional surfactant.
  • cmc critical micelle concentrations
  • Lower cmc causes better solubilization and increased detergency at lower surfactant use levels and unexpectedly enhances the deposition of the soil release polymers as claimed by this invention with demonstrated results to follow herein.
  • Soil removal agents adhere to the fabric being laundered, much better than when mixed with only non-gemini, conventional surfactants.
  • the gemini surfactants result in a low pC 20 value and low Krafft points.
