Several polymer-based capsulation technologies have been developed that not only control fragrance release, but enable the scale-up of profragrance fabrication. However, the thermodynamic method traditionally used in these technologies doesn't support tunable particle size, resulting in uneven size distribution and poor reproducibility.
A study published in the KeAi journal Green Chemical Engineering has introduced a new engineering strategy to construct photo- (or light-) controllable profragrance nanoparticles with the assistance of flash nanoprecipitation (FNP) technology.
FNP uses commercial polymers to encapsulate photo-triggered profragrance in a hydrophobic core.
