Abstract
Described are dissolvable, porous solid structures formed using certain vinyl acetate-vinyl alcohol copolymers. The copolymer and the porosity of the structure allow for liquid flow during use such that the structure readily dissolves to provide a desired consumer experience. Also described are processes for making open cell foam and fibrous dissolvable solid structures.
