We are happy to participate in this meeting held by the RSC Formulation Science and Technology Group (FSTG) looking at Personal Care. The meeting will focus on how to produce more sustainable formulations. It will cover new trends in personal care, packaging, formulating greener, product life cycles and market drivers.

In the talk scheduled at 10:30 prof. dr. ir. Stefan Bon will shortly introduce some of BonLab’s innovations towards greener formulations in personal care. The main focus of the talk will be on our recent work in which we demonstrate the fabrication of surface textured microcapsules formed from emulsion droplets which are stabilized by an interlocking mesh of needle-like crystals. Crystals of the small organic compounds are formed within the geometric confinement of the droplets. Microcapsule diameter can be easily tuned using microfluidics. This approach also proves to be scalable when using conventional mixers, yielding spikey microcapsules with diameters in the range of 10-50 µm. The capsule shape can be molded and arrested by jamming using recrystallization in geometric confinement. We will show that these textured microcapsules show a promising enhanced deposition onto a range of fabric fibers.
