    摘要: 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: (i) an outer layer including a polyurea; (ii) an intermediate layer under the outer layer and including a carbamic-carboxylic anhydride; (iii) an inner layer under the intermediate layer and including an acrylate copolymer; and optionally (iv) an optional outer layer above the outer layer and including a quaternary amine containing moiety, wherein the viscosity of the core can be manipulated from a low viscosity liquid to a semisolid. A method for preparing the composition is also disclosed.
