Title: Interaction between Anionic and Zwitterionic Surfactants: Sodium Dodecyl Sulfate and N‐alkyl‐N,N‐dimethylsulfobetain,N‐lauroylsarcosine
Abstract: The interaction between anionic and zwitterionic surfactant has been investigated through the measurements of surface tension and pH. These systems are sodium dodecyl sulfate (SDS) and N‐alkyl‐N,N‐dimethylsulfobetain(SB) N‐lauroylsarcosine(NL). As the molar ratio of SDS to SB is 7:3, the cmc of these systems exhibits minimum and the surface activity is in‐depend on pH. As the molar ratio of NL to SDS is from 3:7 to 7:3, the synergistic effect of the systems exhibits significantly, the surface tension increases with decreasing of pH and deposits has formed.
