A process for the entrapment of amphiphilic compounds as uncharges on ionic mole ratios of phospholipid to the amphiphilic compound. Preparations of ionic species of amphiphilic compounds in the absence of crystals can be prepared, whilst preparations of uncharged amphiphilic compounds can be prepared with the compound exclusively entrapped inside the liposomes, or partly entrapped inside the liposomes with extraliposomal crystals. |
