Technical Details & Test Data
- Cloud Point Data
To determine hydrotrope capabilities of DePHOS H66 - 872, a series of cloud point tests were performed and compared to competitive phosphate esters and 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 a 9.5 mole nonyl phenol ethoxylate in each caustic and alkaline electrolyte solution, with no hydrotrope added.
