Abstract: Disclosed is a process for encapsulating a water-soluble oral care active agent by a shell comprising a hydrophobic polymer. Two routes are described, both of which involve providing a system comprising a hydrophobic polymer, a solvent selected from the group consisting of ethyl formate, ethyl acetate, methyl acetate, propyl acetate, butyl acetate, isobutyl acetate, isopropyl acetate, isoamyl acetate, and mixtures thereof, an oral care active agent, and an oily liquid such as liquid paraffin. In the first route one first has separate phases (viz. the O/O emulsion) from which one allows precipitation by solvent removal. In the other route, the separate phases are created so as to trigger precipitation. In both routes a temperature rise takes place so as to force solvent removal, resulting in solidification.
