DePHOS™ H-66-872

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.
