The encapsulation of the hydrophobic fragrance 1,2-dimethyl-1-phenyl-butyramide (DMPBA), a typical C9 amide, in poly(methyl methacrylate), polystyrene, or acrylic copolymer nanoparticles can easily be obtained using a one-step miniemulsion process. It is shown that this hydrophobic molecular weight, and the morphology of the nanocapsule formation. The release behavior can be tuned by the temperature in relation to the T-g of the polymer which makes these nanocapsules interesting candidates for temperature-dependent delivery systems.
