• Abstract:

  Polyester (PS) and poly (methyl methacrylate) (PMMA) nanoparticles (NP) loaded with lavender oil were prepared (LO) the first and jasmine (JO) the second. The method used was semi-continuous heterophase polymerization in the presence of the oils, which allowed to obtain NP of PS-LO with average diameters of 16.1 nm and of PMMA-AJ of 27.1 nm. These sizes were determined by the quasi-elastic light scattering (QLS) technique. The NP-oil content in the final latexes were 30.8% in the polymerizations in the presence of lavender oil and 31.1% in those carried out with jasmine oil. The oil contents in the NPs were 26.5 and 22.5% for the PS-AL and PMMA-AJ NPs, respectively.
