Zwitterionic surfactants rheology

An important aspect to be considered concerns the chemical constitution of the polysurfactants. While monomeric surfactants associate to form micelles in aqueous solutions regardless of whether the hydrophilic group is an anionic, cationic, zwitterionic or non-ionic group, it is more complex for the ionic compared to the non-ionic polysurfactants. This is clearly reflected in the rheological properties of ionic polysurfactants(26).
