Emulsion, Secondary emulsion, Polyelectrolyte


The method for the preparation of stable secondary emulsion has been detailed and discussed in terms of polymer capping and emulsion ratio. The dispersion of omega-3 oil in water by emulsion stabilized with casein was further coated with a polycationic polyelectrolyte, Poly (dially dimethyl ammonium chloride). The stability of the emulsion was studied by turbidity measurements using a UV-visible spectrophotometer. The particles size of the primary and secondary emulsion was investigated by light scattering and zeta potential measurements. Results shown in this article provide some details about the mechanism of the formation of secondary emulsion, mainly regarding the polymer/emulsion-mixing ratio.
