A composition (I) comprises at least two different nanoemulsions stabilized by lecithin. Each of the emulsion contains a liquid lipid. At least two of the lipids are incompatible with each other. An independent claim is included for preparation of (I) in which at least one of the lipids is in solid form at room temperature involving: dissolving in oil or in a mixture (a) of oil and organic solvent, separately from the other lipids; at least one of the incompatible solid lipids at a temperature at which it is soluble in the oil or in (a); processing each of the solutions of the lipids separately into an individual nanoemulsion by high pressure homogenization; cooling each of the nanoemulsion down to room temperature to create stable supersaturated solution of the solid lipid; and combining the individual solutions to form (I). Die stabilen Zusammensetzungen bestehen aus mindestens zwei verschiedenen, durch Lecithin stabilisierten Nanoemulsionen, von welchen jede ein flüssiges Lipid enthält, von welchen Lipiden mindestens zwei miteinander nicht kompatibel sind. Es werden Verfahren zu deren Herstellung beschrieben. Die Zusammensetzungen finden in der Kosmetik, in Zellkulturen und in Nahrungsergänzungsmitteln Verwendung.
