ABSTRACT:
This invention relates to solid compositions wherein a non-cosmetic functional material is entrapped in the lattice of the cross-linked polymer during in situ polymerization of the monomers forming the polymer lattice. The invention provides for conversion of solid and/or liquid products into solid, free-flowing forms by entrapment of the functional materials in a hydrophobic polymer lattice.
