Hydrocolloid adhesive compositions are disclosed comprising a hydrophobic unsaturated aliphatic homopolymer, a compatible tackifier, and at least one hydrocolloid absorbent. The compositions have enhanced resistance to breakdown by body fluids, adjustable absorbency, improved adhesive and cohesive properties, as well as a reduced tendency to leave an adhesive residue after application. Also disclosed are wound dressings, ostomy or prosthesis adhesives, methods of using wound dressings, and methods for forming the hydrocolloid adhesive compositions.

A pressure sensitive hydrocolloid adhesive composition consisting essentially of i) about 20-50 percent by weight of a hydrophobic, unsaturated, elastomeric homopolymer, ii) about 20-60 percent by weight of a tackifier selected from the group consisting of polyisobutylene, synthetic polyterpene tack

A pressure sensitive hydrocolloid adhesive composition consisting essentially of i) about 20-50 percent by weight of a hydrophobic, unsaturated, elastomeric homopolymer, ii) about 20-60 percent by weight of a tackifier selected from the group consisting of polyisobutylene, synthetic polyterpene tackifiers and combinations thereof and iii) about 5-60 percent by weight of a hydrocolloid absorbent selected from the group consisting of a natural hydrocolloid, a semi-synthetic hydrocolloid, a synthetic hydrocolloid, and combinations thereof, wherein the homopolymer is cross-linked by 5-200 kGy gamma radiation to provide the composition with a cross-linked matrix having a wet integrity value of at least about eighty percent, a shear hold value of at least 500 min/500 g and a dry cohesive strength which prevents adhesive composition breakage or delamination when a 1×6 cm strip of the adhesive composition is slowly peeled off a polyester adhesive tape at a 90 degree angle and at a speed of 10 mm/minute.
