WebFeb 6, 2004 · Cloud point (CP) measurements of Tween 20 and Tween 80 were carried out in the presence of various glycol oligomers and triblock polymers (TBP). The cloud points of both Tween 20 and 80 decrease in the presence of both types of additives. Among the glycol oligomeric additives, ethylene glycol monobutyl ether was found to reduce the CP … WebCloud point is the temperature at which nonionic surfactants become separated from the solution. Below the cloud point, surfactant has higher foaming and above the cloud point, …
WebThe presence of other components in a formulation can depress or increase the cloud point of cleaning solutions. For example, the addition of a hydrotrope can increase the cloud point of a solution, whereas builders will depress the cloud point temperature. Cloud points are typically measured using 1% aqueous solutions of the respective surfactant.
