Opacifying polymers

A manufacturing process for producing a self stabilizing dispersion copolymer comprising:

• polymerizing a hydrophobic moiety and a water-soluble acid-containing monomer in the presence of one or more water-miscible solvents and one or more neutralizing agents, and
• removing the one or more water-miscible solvents from the solution,
• wherein the self-stabilizing dispersion comprises at least one polymerizable acid-containing moiety, wherein the at least one acid-containing moiety is at least partially neutralized before or during polymerization, and at least one hydrophobic moiety.

A process for encapsulating a water insoluble active comprising the steps of:

• polymerizing one or more hydrophobic monomers and one or more water-soluble acid-containing monomers in the presence of one or more water-miscible solvents and one or more neutralizing agents, thereby producing a self-stabilizing solution,
• adding the water insoluble active, and
• removing the one or more water-miscible solvents from the solution.

A personal care formulation comprising a self-stabilizing dispersion comprising at least one polymerizable acid-containing moiety, wherein the at least one acid-containing moiety is at least partially neutralized before or during polymerization, and at least one hydrophobic moiety.

A detergent comprising a self-stabilizing dispersion comprising at least one polymerizable acid-containing moiety, wherein the at least one acid-containing moiety is at least partially neutralized before or during polymerization, and at least one hydrophobic moiety.
