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.
A film-former composition for application to the skin for providing a generally water insoluble, breathable skin barrier film for shielding peristomal skin, perineal skin and the like which comprises on the basis of weight from about 5% to about 12.5% of an acrylic resin selected from the group comprising butyl methacrylate, n-butyl/iso-butyl methacrylate copolymer dissolved in a physiologically acceptable relatively volatile solvent selected from C.sub.3 -C.sub.10 alkanols and including a and minor proportion of a physiologically acceptable plasticizer.
A film-former composition for aerosol application to the skin for providing a generally water insoluble breathable protective barrier film for shielding peristomal skin, perineal skin and the like which comprises on the basis of weight from about 10.5% to about 11.5% n-butyl/iso-butyl methacrylate 50/50 copolymer dissolved in a physiologically acceptable relatively volatile solvent selected from C.sub.3 -C.sub.10 alkanols and plasticized with a minor amount of a physiologically acceptable plasticizer.
A film-former composition for wiping application to the skin for providing a generally insoluble breathable protective barrier film for shielding peristomal skin perineal skin and the like which comprises on the basis of weight from about 10.5% to about 11.5% n-butyl/iso-butyl methacrylate 50/50 copolymer dissolved in a physiologically acceptable relatively volatile solvent selected from C.sub.3 -C.sub.10 alkanols and plasticized with a minor amount of a physiologically acceptable plasticizer.
A film-former composition for application to the skin by means of a textile towelette for providing a generally water insoluble breathable skin barrier film for shielding peristomal skin, perineal skin and the like which comprises on the basis of weight from about 10.5% to about 11.5% n-butyl/iso-butyl methacrylate 50/50 copolymer dissolved in a physiologically acceptable relatively volatile solvent selected from C.sub.3 -C.sub.10 alkanols and plasticized with a minor amount of a physiologically acceptable plasticizer.
A liquid film-former composition for application to the skin by means of gravometric feed of the liquid to a dabbing applicator for providing a generally water insoluble breathable skin barrier film for shielding peristomal, skin, perineal skin and the like which comprises on the basis of weight from about 11.5% to about 12.5% n-butyl/iso-butyl methacrylate 50/50 copolymer dissolved in a physiologically acceptable relatively volatile solvent selected from C.sub.3 -C.sub.10 alkanols and plasticized with a minor amount of a physiologically acceptable plasticizer.
