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.
L'invention porte sur des compositions adhésives hydrocolloïdales, renfermant un homopolymère aliphatique hydrophobe insaturé, un agent collant, et au moins un absorbant hydrocolloïdal. Ces compositions offrent une meilleure résistance au clivage par les fluides corporels, un pouvoir absorbant ajustable, des propriétés d'adhérence et de cohésion améliorées, et elles ont moins tendance à laisser un résidu d'adhésif après application. L'invention porte également sur des pansements, des adhésifs pour stomie ou prothèses, des méthodes d'utilisation des pansements, et enfin des méthodes pour l'obtention des compositions adhésives hydrocolloïdales.
