• A) providing a non-aqueous mixture containing one or more active substance, at least one phospholipid\PL, optionally at least one sterol ST, and optionally a nonaqueous solvent S that is not miscible with water, wherein phospholipid PL and said sterol ST are at least partially dissolved in said nonaqueous solvent S or said one or more active substance,
• B) emulsifying the non-aqueous mixture obtained in step A) with water, optionally supported by stirring and/or surfactants,
• C) optionally adding at least one inorganic salt or mineral having a solubility in water of less than 0.01 wt % at 21° C.
