By analysis of diffuse-reflectance infrared Fourier transform spectroscopy results obtained from core/shell particles, the entrapment of bergamot oil (BO) and benzoyl peroxide (BPO) was compared in different silica and organosilica shells obtained from oil-in-water microemulsions (see spectra). The results point to a number of significant findings on the modality of the sol-gel microencapsulation process.
