Synthesis, Surface Parameters, and Biodegradability of Water-soluble Surfactants for Various Applications.

The synthesis of water-soluble heterocyclic compounds was verified on the basis of nonionic surfactants for use as surface-active agents. Surface characteristics such as surface and interfacial tensions, cloud point, wetting time, emulsion stability, foaming height and foaming stability were measured for these surface factors in aqueous solutions. In addition, the critical micelle concentration (CMC), the surface pressure at CMC (π), the effectiveness of surface tension reduction (pC), the maximum surface concentration (Γ) and the minimum area/molecule at the aqueous solution/air interface (A) were calculated.
