The present invention relates to a novel hydrocolloid adhesive mass useful for medical purposes, characterized in that said hydrocolloid adhesive mass comprises:a) 0.2 to 5 parts by weight of an ethoxylated sorbitan fatty acid ester;b) 20 to 50 parts by weight of a hydrocolloid;c) 32 to 120 to parts by weight of an adhesive matrix made up of one or more polymers selected from poly(styrene/olefin/styrene) block copolymers, low-molecular polyisobutylenes and high-molecular polyisobutylenes, and one or more compounds selected from sticky resins, or tackifying resins, plasticizers, polybutenes, antioxidants, ethylene/vinyl acetate copolymers, butyl rubbers and ethylene/propylene block copolymers; andd) 0 to 15 parts by weight of an acrylate copolymer with a glass transition temperature below -20° C. It further relates to the use of this hydrocolloid adhesive mass for the production of dressings, especially for the treatment of superficial, deep, chronic or acute dermo-epidermal lesions, exudative wounds and bums.
