Claim:
1. A method of making an article from a dissolvable fibrous web structure comprising the steps of: a. preparing a processing mixture comprising one or more active agents, wherein one or more of the active agents are surfactants comprising a sodium laureth sulfate, and one or more water soluble polymeric structurants, wherein the processing mixture has: b. fibrillating the processing mixture into fibers by a fluid film fibrillation process comprising a first pressurized gas stream directed against a liquid film of the processing mixture to form the fibers; c. at least partially drying the fibers of the processing mixture by a second pressurized gas stream; d. depositing the partially dry fibers on a surface to form a web of partially dry fibrous web structures; e. drying the partially dry fibrous web structure to a desired final moisture content; f. applying a surface resident coating; and g. cutting the fibrous web into one or more shapes to form the article.
