A method of making interlinked multilayer microcapsules, which comprises: - providing as a dispersion in an aqueous vehicle, a hydrophobic internal phase comprising a monomer and an active agent of a fragrancing component such as a perfume oil; - mixing a first and second polyelectrolytes in the aqueous vehicle under conditions sufficient to form a suspension of complex coacervate nodules; - depositing the complex coacervate nodules at an interface of an aqueous vehicle adjacent the hydrophobic internal phase to form an outer shell of the microcapsule, wherein the hydrophobic internal phase forms the core and contains the monomer and fragrancing component therein; and - introducing a water soluble reactant into the aqueous vehicle under conditions sufficient to induce interfacial polymerization of the monomer inside the outer shell to form an inner shell at the interface between the internal phase and the outer shell wherein: the first polyelectrolyte carries a net positive charge when the pH is less than 8 while the second polyelectrolyte carries a net negative charge when the pH is greater than 2; the first polyelectrolyte is gelatin and the second polyelectrolyte is selected from the group consisting of carboxymethyl cellulose, sodium carboxymethyl guar gum, xanthan gum and plant gums; and the monomer is an oil soluble isocyanate, and the reactant is guanazol, guanidine, or a salt thereof. - providing as a dispersion in an aqueous vehicle, a hydrophobic internal phase comprising a monomer and an active agent of a fragrancing component such as a perfume oil; - mixing a first and second polyelectrolytes in the aqueous vehicle under conditions sufficient to form a suspension of complex coacervate nodules; - depositing the complex coacervate nodules at an interface of an aqueous vehicle adjacent the hydrophobic internal phase to form an outer shell of the microcapsule, wherein the hydrophobic internal phase forms the core and contains the monomer and fragrancing component therein; and - introducing a water soluble reactant into the aqueous vehicle under conditions sufficient to induce interfacial polymerization of the monomer inside the outer shell to form an inner shell at the interface between the internal phase and the outer shell wherein: the first polyelectrolyte carries a net positive charge when the pH is less than 8 while the second polyelectrolyte carries a net negative charge when the pH is greater than 2; the first polyelectrolyte is gelatin and the second polyelectrolyte is selected from the group consisting of carboxymethyl cellulose, sodium carboxymethyl guar gum, xanthan gum and plant gums; and the monomer is an oil soluble isocyanate, and the reactant is guanazol, guanidine, or a salt thereof. the first polyelectrolyte carries a net positive charge when the pH is less than 8 while the second polyelectrolyte carries a net negative charge when the pH is greater than 2; the first polyelectrolyte is gelatin and the second polyelectrolyte is selected from the group consisting of carboxymethyl cellulose, sodium carboxymethyl guar gum, xanthan gum and plant gums; and the monomer is an oil soluble isocyanate, and the reactant is guanazol, guanidine, or a salt thereof.
