PSO 4 significantly decreases the particle size of the multilamellar liposomes (MLVs). The sizes of the vortexmixed and the bath-sonicated liposomes vary as a function of PSO 4 concentration. On the other hand, PSO 4 has only little effect on the particle sizes of probe sonicated liposomes. In some cases, the liposomal stability at higher PSO 4 concentrations depends on the preparation method. PSO 4 improves the dispersibility of the DPPC liposomes and enhances their hydration. It also increases the fluidity of the liposomes prepared by each method. Our results suggest that liposomes consisting of DPPC and PSO 4 can be suitable as a cosmetic or pharmaceutical ingredient for the effective delivery of the active components into the body.

PSO 4 was found to enhance hydration in the headgroup region of DPPC bilayers. Therefore, with the incorporation of PSO 4 into DPPC membranes, the amount of water required to reach the fully hydrated state was enhanced as indicated by the constant values of the main phase transition temperature (T m) and the bilayer repeat distance (d). For example, with the addition of 20 mol% of PSO 4 , the saturation point was shifted to ~70 wt% water compared to ~40 wt% for pure DPPC and 47 wt% for DPPC-cholesterol. The effectiveness of PSO 4 in fluidizing the membrane and enhancing its hydration state can be useful in the pharmaceutical and cosmetic industries.
