By controlling adequate preparation conditions and selecting polymer materials as the shell in microencapsulation, shells with various thickness, hardness, aqueous solubility, and molecular weight can be produced. Microcapsules loaded with perfume as the core material, which has a proper delivery characteristic, were prepared by in-situ polymerization methods. Some polymeric resin were used to form the shell of the capsules. The size and size distribution of the capsules were determined using an optical microscope and particle size analyzer. The thermal properties were also investigated using a differential scanning calorimeter (DSC). |
