Environmentally biodegradable compositions comprising an amino acid adduct, controlled release particles and compositions comprising same, and methods of making same

Abstract

Disclosed is a controlled release particle including a core including at least one hydrophobic active ingredient, optionally a sugar alcohol, and optionally a plasticizer; and a shell including a reaction product of (a) at least one isocyanate resin and at least one epoxy resin with (b) at least one treated protein isolate, at least one mono epoxy alkoxy silane, at least one hydrolyzed organofunctional silane, at least one gelatinized polysaccharide, at least one amino polysaccharide and at least one adduct. The at least one adduct is at least one amine-acid functional urea linked amino acid isocyanate adduct and/or at least one amine-hydroxy-acid functional amino acid epoxide adduct. Further disclosed are a controlled release composition including a plurality of the particles, and a method of making the controlled release particle.
