41115.5 Large-scale manufacture of particulate-based proliposomes
Depending on preparation conditions, liposomes generated from solvent-based
proliposomes have been demonstrated to be OLVs [49], MLVs [64], a mixture of
MLVs and OLVs [65,66], or, under static conditions, LUVs with the occasional pres-
ence of MLVs [67].
Liposomes generated from ethanol-based proliposomes provide very high entrap-
ment of hydrophilic materials, which ranged between approximately 65% and 80%
depending on phospholipid composition [49] and from approximately 30% to 85%
depending on hydration procedure [64]. Different materials may have different
entrapment efciencies ...
