Abstract:
A process for encapsulating a water insoluble active including forming a solution by polymerizing one or more hydrophobic monomers and one or more water-soluble acid-containing monomers in the presence of water and one or more water-miscible solvents and one or more neutralizing agents, adding the water insoluble active, and removing the one or more water-miscible solvents from the solution.
