| Complex coacervation and interfacial polymerization are both methods of microencapsulation that have previously been successfully used to encapsulate various core materials. In this experiment, both methods were tested in the pursuit of encapsulating N,N-dimethyl-p-toluidine, a slightly basic core material. Pot life studies and frontal system tests (with benzoyl peroxide) were performed on capsules formed through the use of both methods. The capsules produced by interfacial polymerization were much more stable than those formed by complex coacervation, although the capsules formed by complex coacervation showed some stability in frontal systems with benzoyl peroxide that was also encapsulated. |
