PRODUCTION OF UNIT DOSE CONSTRUCTS

摘要

Dissolvable unit dose constructs and their method of manufacture are disclosed in which the unit dose constructs are formed of a composition including a polymer matrix that includes a water soluble polymer, active ingredient, and a liquid carrier. The composition is deposited directly, such as by stenciling, to form individual unit doses without the need to cut and convert long, continuous rolls of film.

主权项

1. A method of forming a dissolvable unit dose construct comprising:
providing a first composition comprising a water soluble polymer and a liquid carrier; depositing the first composition onto a substrate; providing a second composition comprising a water soluble polymer and a liquid carrier; stenciling the second composition at a plurality of discrete locations overlying the first composition; and removing at least a portion of the liquid carrier from the first and second compositions to form a multi-layer unit dose construct.
