Stabilized chemical composition

A method comprising:

• a. preparing a non-aqueous curable liquid comprising a melt of at least one suitable solidifiable thermoplastic polymer and optionally an plasticizer;
• b. emulsifying said non-aqueous curable liquid into a heated aqueous liquid to a mean droplet size of 1-200 microns, which aqueous liquid contains a colloidal solid as an emulsion stabilizer and optionally contains a plasticizer;
• and
• c. cooling the emulsion, and optionally thereafter imbibing a plasticizer, to produce thermoplastic polymeric particles in the emulsion and a colloidal solid material at the surface of the particle;
• and
• d. adding at least one active ingredient to the emulsion to produce thermoplastic polymeric particles having a hardness of the particles that is greater than 0.001 MPa and less than 6 MPa with the active ingredient distributed therein.

A method comprising:

• a. preparing a dispersion concentrate by dissolving or suspending at least one active ingredient in a non-aqueous curable liquid mixture comprising at least one suitable cross-linkable resin comprising monomers, oligomers, prepolymers or blends thereof, optionally where the resin contains hydrophilic groups, optionally a suitable hardener, catalyst, plasticizer or initiator,
• b. emulsifying said dispersion concentrate in to an aqueous liquid to a mean droplet size of 1-200 microns, where the liquid contains a colloidal solid as an emulsion stabilizer, optionally contains a plasticizer, and, optionally, certain suitable hardener, catalyst or initiator capable of diffusing into the dispersed uncured resin droplets;
• and
• c. effecting crosslinking or cure of the cross-linkable resin mixture, and optionally thereafter imbibing a plasticizer, to produce an emulsions comprising cured thermoset polymeric particles with at least one active ingredient distributed therein, and a colloidal solid material at the surface of the particle;
• and
• d. adding an additional amount of an active ingredient to the emulsion to produce cured thermoset polymeric particles having a hardness of the particles that is greater than 0.001 MPa and less than 6 MPa with the active ingredient, or ingredients, distributed therein.
