1. An aggregate article comprising:
a plurality of scent reservoirs comprising an absorbent matrix material having a three-dimensional structure with a plurality of pores within the three-dimensional structure; and
a volatile composition, wherein the volatile composition at least partially fills the plurality of pores; and
a modulating coating, which is applied to the absorbent matrix material to form the three-dimensional structure via heat resistant bonds;
wherein the modulating coating comprises a barrier substance and a hygroscopic substance; and
wherein the hygroscopic substance is sized to attract water vapor without attracting liquid water and facilitates a release of the volatile composition through the modulating coating.
