Abstract:
A method of encapsulating a pheromone, comprising:a) providing a solution comprising a first polymer capable of forming a microcapsule by complex coacervation; a pheromone; and a second polymer, said second polymer being capable of forming a microcapsule by complex coacervation with the composition comprising the first polymer; b) establishing a microcapsule having a coacervation shell without chemical crosslinking of said shell; c) adding a third polymer, said third polymer being suitable to form a hydrogel microbead, in an amount effective to form a microcapsule containing composition; and d) spraying the microcapsule containing composition into a coordination solution, thereby providing stable hydrogel microbeads comprising microcapsules having a coacervation shell without chemical crosslinking.
