ABSTRACT:
A copolymer-based film former composition and delivery system is disclosed for establishing a breathable, compliant, water-insoluble barrier film for protection of the skin from exposure to, and irritation by, urine or fecal waste. The film formed establishes a protective barrier film that aids in maintaining a normal skin environment such as at the site of an interface between the skin and the adhesive of an ostomy appliance. In a preferred embodiment the copolymer comprises a plasticized solution of 50/50 n-butyl/iso-butyl methacrylate. The film former is applied to the skin by delivery means adapted to essentially preclude cross-contamination, assure that the film intimately conforms to the skin, and in a preferred delivery system enables the essentially simultaneous removal of a previously deposited film with stomal contaminant thereon while establishing a new film formed of the copolymer composition.
