- emulsions are emulsions of emulsions that can be present in two main types, namely W / O / W and O / W / O emulsions. These systems are of great interest in many applications. They allow on the one hand the protection of the active substances in the innermost phase, on the other hand, the introduction of two reacting active substances in two phases of the same formulation. In addition, prolonged efficacy of the drugs in the innermost phase following administration to organisms can be observed.

- the final emulsion droplets have a mean diameter of 10 to 16 ⁇ m. All these procedures are tailored to one area of application and therefore can not simply be transferred to other areas of use.
- the invention is based on the object to form a stable double emulsion of the type 1) W / O / W, wherein the outer and / or the inner aqueous phase, a pharmaceutical agent, e.g. in the form of an antigen, and whose oily phase contains a surfactant which acts as an emulsifier.
- the droplet size of the oil phase should in particular not exceed the mean diameter of 3 .mu.m, that of the inner aqueous phase of 0.3 .mu.m.
- the method should in particular have a narrower droplet size distribution and, associated therewith, a higher reproducibility than conventional methods.
- heterogeneous and partially agglomerated drug particles are not limited by their size, e.g. separated by the membrane used or destroyed by shearing.
- the formation of the simple emulsion occurs e.g. according to the basically known stirring process.
- the droplet size (number average) is typically between 10 to 30 microns, the said phase inversion temperature usually 60 to 90 ° C.

- emulsifier which, depending on the composition, is initially introduced in the aqueous a) and / or oil-containing phase b); in the preferred process it is present as nonionic emulsifier in the oil phase b).
- the process is particularly preferably carried out in a temperature range with respect to the emulsification after step a) from 30 ° C to 35 ° C and with respect to the phase inversion a temperature gradient of 3 OK but at least 15K.
- the active ingredient introduced in the aqueous phase can be, for example, a pharmaceutical active substance, preferably for veterinary purposes, in particular an antigen for a vaccine formulation.
- the active ingredient is selected from the series:
- An antigen such as a virus, a microorganism, more specifically a bacterium or parasite, or a preparation containing a peptide chain.
- This preparation may be a protein or a glycoprotein, especially a protein or a glycoprotein obtained from a microorganism, a synthetic peptide or a rotein or peptides produced by genetic manipulation.
- the above-mentioned virus and / or microorganism may be completely inactivated, live or attenuated.
- virus which represents an antigen
- rabies virus As a virus, which represents an antigen, may be preferably named: rabies virus, Aujeszky viruses, influenza viruses, the virus of foot-and-mouth disease and HTV viruses.
- microorganism or a bacterial species which is an antigen there may be mentioned preferably E.coli and those of the strains Pasteurella, Furonculosis, Vibriosis, Staphylococcus and Streptococcus.
- parasites may be mentioned preferably those of the strains Trypanosoma, Plasmodium and Leishmania.
