The ability of additives to reinforce the cryoprotective effects of cycloinulohexaose (CF-6) during the freeze-drying of liposomes was investigated. Using CF-6 with ethylene glycol, propylene glycol, glycerol and proline, the retention of calcein in freeze-dried liposomes was increased compared with the use of CF-6 only. The results of Fourier transform infrared spectroscopy (FTIR) suggested that one of the reasons for this difference was the increase in the ratio of hydrogen bonding between lipid and CF-6 with additives. The results of differential scanning calorimetry (DSC) suggested that critical distance between lipids molecules is thought to be maintained by this interaction. Because of this distance, the intermolecular interaction of lipids may be weakened. Using glycerol as the additive, when the ratio of glycerol to CF-6 increased from 0 to 0.2 (w/w), the retention of calcein in the freeze-dried liposomes increased from 72.9±5.1% to 85.0±1.0% and attained a maximum at the ratio of 0.15.
