Formulations for metal catalysis in water comprising a surfactant and a lipophilic compound

A method for for carrying out a catalyzed reaction in an aqueous medium with a dry formulation obtained by drying an emulsion, wherein the dry formulation comprises at least one surfactant and at least one lipophilic compound, wherein:

• the at least one surfactant is selected from the group comprising dendrimers of Dendri-TAC type, oligomers of FiTACn or HiTACn type, TPGS 1000, TPGS 750 M, surfactants derived from sugars and/or amino acids, and combinations thereof;
• the at least one lipophilic compound is selected from the group comprising lipids, hydrophobic complexing agents and combinations thereof;
• the method comprising the following steps:
• bringing together water with the dry formulation, resulting in the formation of an emulsion comprising:
• a discontinuous phase comprising droplets including the at least one surfactant and the at least one lipophilic compound, and
• a continuous aqueous phase;
• bringing together at least one metal catalyst comprising a metal selected from Groups 3 to 12 of the Periodic Table with the dry formulation or with the emulsion formed by bringing together water with the dry formulation.
