Cloud point, polymeric surfactants, emulsion

Carrying out an emulsion polymerization requires an awareness of the krafft point of an ionic surfactant and the cloud point of a nonionic surfactant. Micelles are formed only at temperatures above the Krafft point of an ionic surfactant. For a nonionic surfactant, micelles are formed only at temperatures below the cloud point. Emulsion polymerization is carried out below the cloud temperature of a nonionic surfactant and above the Krafft temperature of an ionic surfactant. 

MgS04, stability could be maintained at high temperatures up to 1 mol/dml Thus, these cloud point measurements give conclusive evidence of the unique behavior of polymeric surfactants based on inulin. The poly fructose chain remains hydrated up to high temperatures and in the presence of high electrolyte concentrations. Thus, by adequate design of the polymeric surfactant, one can achieve very high stability for the emulsions.
