Liposomes are the best carrier for effective delivery of bioactives in the deep skin areas. In the present study, a comparative study of liposomes was carried out using thin film hydration and curvature tuned methods. Liposomes were prepared using cholesterol, soy lecithin and Span 80. The liposomes were evaluated for physical characterization, morphology, surface charge and release properties. Liposomes prepared by the thin film hydration method (formulation TACTL2) had better properties compared to liposomes prepared by the curvature tuned method (formulation TACCT2) in terms of entrapment efficiency (78.5±1.8% vs 53.4±5.6%), particle size (411.8 nm vs 630 nm), surface morphology(round and dispersed particles vs aggregates and lumps), and release profile (70.1% vs 32.87% in 12 h). Based on the results it is concluded that the thin film hydration method is better than a curvature tuned method for the preparation of liposomes.
