The six fragrances, camphor, citronellal, eucalyptol, limonene, menthol and 4-tert-butylcyclohexylacetate, which represent different chemical functionalities, were encapsulated with a polymer-blendof ethylcellulose (EC), hydroxypropyl methylcellulose (HPMC) and poly(vinyl alcohol) (PV(OH)) usingsolvent displacement (ethanol displaced by water). The process gave≥40% fragrance loading capacitywith≥80% encapsulation efficiency at the fragrance to polymer weight ratio of 1:1 and at initial polymerconcentrations of 2000–16,000ppm and the obtained fragrance-encapsulated spheres showed hydrody-namicdiametersoflessthan450nm.Thereleaseprofileoftheencapsulatedfragrances,evaluatedbyboththermal gravimetric and electronic nose techniques, indicated different release characteristics amongstthe six encapsulated fragrances. Limonene showed the fastest release with essentially no retention bythe nanoparticles, while eucalyptol and menthol showed the slowest release
