CONTINUOUS PROCESS OF MAKING AN ARTICLE OF DISSOLUTION UPON USE TO DELIVER SURFACTANTS

A continuous process for making a flexible porous dissolvable solid structure with open celled foam. The continuous process has the steps of preparing a pre-mixture comprising surfactant, polymer, water, and optionally plasticizer; aerating the pre-mixture to form a wet aerated pre-mixture; extrudin...

Zusammenfassung:	A continuous process for making a flexible porous dissolvable solid structure with open celled foam. The continuous process has the steps of preparing a pre-mixture comprising surfactant, polymer, water, and optionally plasticizer; aerating the pre-mixture to form a wet aerated pre-mixture; extruding the wet aerated pre-mixture to form one or more sheets on a belt; and drying the sheets to form an Article having an open celled foam.
