    2011-1-3 · One zwitterionic polyacrylamide (PAM-Z) was tested in the presence of an anionically modified polyacrylamide (PAM-S). The rheological behavior shows a synergistic effect when the proportion for each polymer was changed. When NaCl is added the synergistic effects disappear due to the screening of the charges present in both polymers.

  • Controlling Selectivity on Zwitterionic HILIC Columns

    Novethix™ L-10 polymer is a highly efficient, hydrophobically-modified alkali-swellable emulsion polymer designed for structuring most cleansing formulations containing anionic, nonionic, and zwitterionic surfactants. It is particularly effective for thickening and rheology control of the most challenging surfactant systems.
