Abstract
A fragrance delivery system is disclosed whereby multiple fragrances can be released on demand. The fragrance delivery system includes a plurality of microcells, wherein each of the plurality of microcells is filled with a fragrance composition. Each of the plurality of microcells includes an opening, the opening being spanned by a porous sealing layer. The fragrance delivery system provides a tool to deliver a customizable olfactory effect in the vicinity of the fragrance delivery system.
