Nonionic; Formulations. … 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.

Cloud point analysis: Influence of additives on polysorbate

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 … WebThis study investigated a simple, sensitive, and selective method for the colorimetric assay of silver nanoparticles (AgNPs) using Triton X-114-based cloud point extraction (CPE) as a preconcentration step and Tween 20-stabilized gold nanoparticles (Tween 20-AuNPs) as a colorimetric probe. After heating beyond the cloud point temperature of Triton X-114, a … WebCloud point temperature of Tween 20 (5 mol dmu00013) and Tween 80 (1 mol dmu00013) has been determined in the presence of various salts in addition to glycols.
