Technical Details & Test Data

Technical Information

Cloud point data for  DePHOS™ H-66-872

  • A series of cloud point tests were performed and compared to sodium xylene sulfonate.
  • The hydrotropes were solubilized in caustic or alkaline electrolyte solutions to which a 9.5 mole nonyl phenol ethoxylate was added.
  • Each sample was heated to the temperature at which the nonionic clouds out of solution.
  • The higher the cloud point temperature, the more efficient the hydrotrope.
  • The control is 1% NPE-9.5 without hydrotrope added.
