Abstract: Disclosed is a composition including microcapsules, which include: a core composition including at least one hydrophobic active ingredient; and a wall partially or completely surrounding the core, wherein the wall includes at least one wall material that is a reaction product of a wall-forming reaction selected from: (A) a Type A reaction including: (i) reacting an amine moiety containing material with an epoxy and optionally an isocyanate; and (ii) reacting the isocyanate and at least one polyol; (B) a Type B reaction of a hydrolyzed protein with at least one of an epoxy and an organofunctional silane, and optionally an isocyanate; and (C) a Type C reaction of an amine moiety containing material with at least one of an epoxy and an oil soluble dialdehyde, and optionally an isocyanate. A method for preparing the composition is also disclosed.

Abstract: Disclosed is a composition including controlled release particles, wherein each of the controlled release particles includes: (a) a core including at least one hydrophobic active ingredient; and (b) a wall at least partially surrounding the core and including the reaction products of: (i) an organofunctional silane; (ii) an epoxy; (iii) an amine; (iv) an isocyanate; (v) an epoxide curing agent; (vi) a basified biodegradable resin; (vii) a pre-reacted natural material resin; (viii) a pre-reaction product of polyisocyanate; wherein the controlled release particles are effective to retain the at least one hydrophobic active ingredient upon exposure to water and effective to release the at least one hydrophobic active ingredient in response to friction. A method for preparing the composition is also disclosed.
