Abstract
A pressure sensitive adhesive composition suitable for medical purposes comprising a rubbery elastomeric base and water soluble or water swellable hydrocolloids, where the adhesive composition includes a substantially homogeneous mixture of 15-60% of one or more rubbery components, 10-60% of a mixture of hydrocolloids that includes a cellulose derivative, amidated pectin, and potato starch, 0-50% of one or more tackifier resins, 0-15% cohesive strengthening agent, 0-10% of a plasticizer and 0-5% pigment. The adhesive shows at least as good properties as state of the art adhesives comprising gelatine with respect to resistance to biological fluids, adhesion to skin, and coherence.
