Cloud point determination of surfactants is typically performed with a 1% weight dilution of the water-soluble surfactant in water. Alcohols, methanol and isopropanol enhanced the cloud point of nonionic surfactants. Cloud point temperatures (CPTs) of selected nonionic surfactants were studied against the effect of added … :LOUD POINTS OF HEPTAOXYETHYLENE DODECYL ETHER IN PRESENCE OF ADDITIVES C 1285 surfactant solution or surfactant solution containing the studied additive. Cloud point phenomena in mixtures of anionic and cationic … Cloud point This is an indicator of the tendency of a fuel to form wax crystals when cold. Cloud Point The cloud point is situated at 19 degrees C for 2 wt% of surfactant. The CP of OPEO30 is higher than 100 °C due to its approximately 30 oxyethylene units per molecule, which limits its use in cloud point extraction (CPE) procedures at room temperature. They are also compatible with solutions of either anionic or cationic surfactants. Cloud points in ionic surfactant solutions | Request PDF Stepan Company - Nonionic Surfactant Cloud Point
