Dynamic interfacial tension at the boundary of aqueous solutions of octylphenyl ethers of poly(ethylene glycols) and hydrocarbon. 1. Theory

Theoretical models describing the diffusion-controlled kinetics of adsorption from surfactant solutions at the surface of a growing drop were considered. The approximated equation for interfacial tension was derived for the dynamic variation in the droplet volume. The theory was extended to the case of surfactant molecules capable of reorienting in the surface layer. Various correction procedures accounting for hydrodynamic effects were analyzed.
