Abstract:

In this study, egg yolk lecithin, cholesterol,and ceramide were used as film-forming materials to prepare collagen ceramide liposomes (CO-CS) by the thin film dispersion method. To optimize the process, encapsulation efficiency was used as the response value, and it was evaluated by influencing factors such as drug-lipid ratio, film-material ratio, ultrasonic time, and hydration time. Results showed that encapsulation efficiency reached 90.73% when the drug-lipid ratio, film-material ratio, and ultrasonic time were 1:16, 4.3:1, and 8.5 min, respectively. Under these conditions, the particle size, polymer dispersity index (PDI), and zeta potential of CO-CS were(206.63±2.06) nm, 0.187±0.010, and (34.90±0.82) mV, respectively. After 60 days of storage at room temperature in the dark, the encapsulation efficiency was 87.2 %. Furthermore, the particle size, PDI, and zeta potential of CO-CS changed to (223.70±1.85) nm, 0.174±0.013, and (33.51±2.10) mV, respectively. In summary, CO-CS produced in this study revealed high encapsulation efficiency and good stability, and the preparation process is reasonable and feasible.
