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

A controlled release particle comprising:

• a core that comprises at least one hydrophobic active ingredient, optionally a sugar alcohol, and optionally a plasticizer;
• and
• a shell that comprises 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, wherein the at least one adduct is at least one of:
• (i) at least one amine-acid functional urea linked amino acid isocyanate (AAI) adduct having a structure represented by Formula I:
• and salts thereof, and
• (ii) at least one amine-hydroxy-acid functional amino acid epoxide (AAE) adduct having a structure represented by Formula II:
• and salts thereof, where
• R1 is a moiety of a monomer or a prepolymer comprising two —NCO functional groups wherein the NCO functional groups have reacted to form urea linkages;
• R2 is a moiety of a monomer or a prepolymer comprising two glycidyl ether epoxide functional groups wherein the epoxide groups have reacted to form amino alcohol groups;
• R6, R7, R20 and R21 are each independently (CH2)n, wherein n is 1-6;
• R8, R9, R10 and R11 are each independently hydrogen or CH2X;
• R12 and R13 are each independently hydrogen, an alkali metal cation, or X;
• R14 and R15 are each independently hydrogen, an alkali metal cation, or X;
• R16 and R17 are each independently hydrogen or X;
• R18 and R19 are each independently hydrogen, SiO3 or X;
• and
• each occurrence of X is independently selected from the group consisting of hydrogen and a substituent.
