  • Rapidly dissolvable polymer films and articles made therefrom
    Patent number: 7547737
    Abstract: A film-forming composition for use in preparing water-soluble films that are rapidly dissolving under cold water conditions, the composition comprising a water soluble polymer material such as polyvinyl alcohol and a principal solvent, typically diol(s) or derivative of a diol. Films made from the film-forming compositions may be used to encapsulate a variety of compositions for subsequent release into an aqueous medium. Encapsulated compositions can include various laundry detergents and additives, fabric care compositions such as fabric softening compositions and dishwashing detergents among others. When used to encapsulate compositions, the solvent system used in the film-forming composition will have at least one common solvent material as the solvent system used in the encapsulated composition to improve film dissolution and to prevent problems associated with solvent migration.
