| Abstract: | By means of differential scanning calorimetry and electron microscopy the miscibility properties of the system dipalmitoyllecithin/dipalmitoyl-N-methyl-cephaline/ water (50 wt-% water) was studied. In theL α-phase (high temperature phase) both phospholipids were completely miscible. On the other hand in the low temperature phases demixing occurs in the concentration range fromx MPE?0.05 tox MPE?0.35. The electron microscopy confirms these results. The electron microscopic pictures showed the ripple structure of theP β phase. |
