Shaped compositions are provided for use in delivering a substantially uniform concentration of a functional agent (e.g., an antimicrobial sanitizing agent) to a flowing stream of water. The composition may be shaped and sized to be inserted into a device configured to be attached over the end of a faucet. The shaped composition may include at least two different regions (e.g., layers). A dissolvable region includes a functional agent (e.g., an anti-microbial sanitizing agent). A substantially non-dissolvable region is disposed adjacent to the dissolvable region (e.g., adjacent the bottom surface) so as to cover a bottom surface of the dissolvable region. The geometry of the shaped composition, as well as the presence of the substantially non-dissolvable region aids in providing a substantially uniform concentration of functional agent throughout the life of the dissolvable region.
