Abstract: A skin cleansing article configured to deliver cosmetics or dermal therapies to a user's skin and a method of making the same are provided. For example, the skin cleansing article includes a core substrate comprising a resin. The core substrate has a first region containing a first active cleansing formulation and a second region containing a second active cleansing formulation. The skin cleansing article is substantially dry or solid and is water-dispersible or water-soluble. When the water-soluble core substrate is contacted with water having a temperature greater than 10° C. for a period of time, the core substrate is dispersible or soluble according to Testing Method MSTM-205 to release the first active cleansing formulation and/or the second active cleansing formulation.

Abstract: Disclosed herein are water-soluble films including a polyvinyl alcohol (PVOH) resin blend and optionally one or more additional components such as plasticizers, fillers, surfactants, and other additives. The PVOH resin blend includes a first copolymer including a first anionic monomer unit and a second PVOH copolymer including a second anionic monomer unit. When the PVOH copolymers are blended in particular proportions and/or selected with regard to various criteria related to physical and chemical film properties, the resulting water-soluble film formed from the PVOH resin blend exhibits maintained film stiffness, and pouch tautness when in contact with liquid pouch contents, maintain acceptable clarity properties, and/or demonstrate acceptable band release without impairing the ultimate solubility of the water-soluble film.
