Abstract
A gel includes a multi-component scented mixture in which the components act in concert to create a perceived scent, disposed in a polymer matrix comprising the polymerization product of one or more ethylenically unsaturated monomers. The monomers are selected such that the gel (a) has sufficient mechanical integrity to retain its shape under ambient conditions and (b) releases the components of the scented mixture in a manner that substantially preserves the native scent of the mixture upon release.
