<p>The invention concerns a novel hydrocolloid adhesive mass useful for medical purposes characterised 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 parts by weight of an adhesive matrix consisting of one or several polymers selected among poly(styrene-olefin-styrene) sequenced copolymers, low molecular weight polyisobutylenes, high molecular weight polyisobutylenes, and one or several compounds selected among the sticky resins called tackifiers, plasticizers, polybutylenes, antioxidants, ethylene and vinyl acetate copolymers, butyl rubber and ethylene-propylene block copolymers; and d) 0 to 15 parts by weight of an acrylate copolymer with glass transition temperature lower than -20 °C. The invention also concerns the use of said hydrocolloid adhesive mass for producing bandages in particular for treating superficial, deep, chronic or acute surface dermoepidermal sores and for treating exsudative wounds and burns.</p> |
