Abstract:
Dissolvable unit dose film constructs are made by providing a muco-adhesive composition including a muco-adhesive polymer matrix in which the muco-adhesive polymer matrix has a water-soluble polymer, water-dispersible polymer, water-swellable polymer, or combinations thereof and a liquid carrier. The method further includes drying the muco-adhesive composition to remove at least a portion of the liquid carrier, forming a muco-adhesive film substrate, forming a composition for an active layer, the composition including a polymer matrix in which the polymer matrix for the active layer composition includes a water-soluble polymer, water-dispersible polymer, water-swellable polymer, or combinations thereof, an active ingredient and a liquid carrier. The method further includes depositing the composition for the active layer onto the muco-adhesive substrate as a plurality of individual volumes and removing the liquid carrier from the plurality of deposited individual volumes to form a plurality of dissolvable film active layers on the muco-adhesive substrate.
