Compositions Comprising Solid Particles Encapsulated In A Cross-Linked Silicone Matrix, And Methods Of Making The Same

A method for forming treated particles, comprising:

• (a) coating core particles having an average particle size ranging from about 0.001 micron to about 0.5 micron with silicone;
• (b) contacting the coated particles with a cross-linking agent, wherein the cross- linking agent comprises a stannous carboxylate capable of effectuating cross-linking of the silicone coating, thereby forming a cross-linked structure with the core particles encapsulated therein;
• and
• (c) reducing the cross-linked structure into treated particles having an average particle size ranging from about 1 micron to about 50 microns, wherein each of the treated particles comprises one or more of said core particles encapsulated in a cross-linked silicone matrix.
