Abstract
A pressure sensitive adhesive composition particularly suitable for use as a protective skin barrier material for sealing the faceplate of an ostomy appliance, such as the faceplate of a one-piece or two-piece urostomy or an ileostomy appliance, to skin surfaces surrounding a patient's stoma. The composition includes a blend of two viscoelastic adhesive elastomers, specifically, high molecular weight polyisobutylene and a styrene block copolymer, which, along with a plasticizer (preferably petrolatum) and a suitable tackifier and antioxidant, form a continuous phase in which hydrocolloids such as sodium carboxymethylcellulose and pectin are dispersed. The composition is exceptional for its durability, flexibility and strength, even when saturated, and for its controlled swelling upon hydration.
