Nanotechnological approach has recently been introduced into fragrance applications. One of these strategies involves encapsulation of fragrances in zeolites to tailor products with controlled release properties. In this study, encapsulation/release of a fragrance molecule, triplal, has been studied using zeolite X as a fragrance carrier. Two phase-pure zeolite X products with different average particle diameters 20 mu m and 4 mu m were synthesized hydrothermally. The desorption kinetics of triplal in these two different zeolite X products was investigated to determine the effect of the particle size on the desorption process. The first order three-stage kinetics model results indicated that larger crystals had slightly lower desorption rate constants. (C) 2015 Elsevier Inc. All rights reserved.
