Abstract
An improved fragrance delivery system capable of providing controlled release of fragrance molecules in various consumer products is composed of a polymer having covalently bound fragrance moieties that are releasable in the form of fragrance molecules. Certain embodiments comprise globular polymer particles in which unbound fragrance molecules are occluded, absorbed and/or adsorbed. Certain other embodiments incorporate fragrance monomer units, which achieve reduced residuals upon complete release of the fragrance.
