Lipids in aqueous phase Abstract The present invention relates to a novel advantageous process for the preparation of unilameller liposomes in aqueous phase by converting a suitable lipid component, e.g. phosphatidic acid, into the ionic form by subjecting the lipid dispersion to a change in pH value and subsequently neutralising it. Formation of the unilamellar liposomes is spontaneous, i.e. it takes place without additional external supply of energy. The liposomes obtainable by the process of this invention can be used therapeutically as carriers for drugs of the most widely different kind.
