Enzyme inhibiting adhesives
View Patent ↗An adhesive composition including an adhesive component and an enzyme inhibiting component for use in ostomy and wound care applications. The enzyme inhibitors are derived from tubers, such as potatoes. In ostomy, the adhesive composition helps to secure the collection bag or pouch to the skin. In wound care application, the adhesive composition secures the wound dressing to the skin. The adhesive composition also may be used to couple two or more ostomy or wound care components together.
1. An adhesive composition for use in an ostomy appliance to provide adhesion and inhibit fecal enzymes, said composition comprising:
a pressure-sensitive, gelatin-free hydrocolloid adhesive component; and
an enzyme inhibiting protein component derived from potatoes, wherein the combined components provide adhesion and inhibit the fecal enzymes chymotrypsin, trypsin, elastase and pepsin, said inhibition increasing over at least 4 hours at 37° C.
2. The adhesive composition of claim 1 , wherein said adhesive component is a rubber-based polyisobutylene.
3. The adhesive component of claim 2 comprising 40% polyisobutylene, 20% carbomethylcellulose, 20% pectin and 20% protagold potato protein.
4. The adhesive composition of claim 1 , wherein said enzyme inhibiting component is Protagold potato protein.
