  An air freshening composition including porous carrier particles having a perfume composition entrapped therein, and a second component selected from an inert filer, hygroscopic agent, binder, coating material, moisture providing agent, and mixtures thereof. The composition may further comprise various optional components such as free perfumes, colorants, disintegrants, water swelling agents, porosity modifiers and mixtures thereof. A method for processing the compositions into a solid article includes the steps of entrapping a perfume in the porous carrier particles, heating and incorporating a carrier or binder material. The compositions may be further processed by optionally incorporating a powder inert filler and forming articles from the mixture. The articles may be formed from the compositions through prilling, extrusion, or compaction amongst other techniques. The air freshening articles and compositions will provide a sustained and controlled release of the perfume compositions over a long period of time without the use of a heat to activate the release. Articles of manufacture including the air freshening articles and various packaging are also disclosed.
