Title (EN) FLUID ABSORBING, ADHESIVE HYDROCOLLOID COMPOSITIONS
(FR) COMPOSITIONS HYDROCOLLOIDALES ADHESIVES ABSORBANT LES FLUIDES
Abstract:
(EN) A fluid-absorbing, composite material that is pressure sensitive adhesive and which is made of a mixture comprising a continuous phase formed from a pressure sensitive adhesive matrix, and a discontinuous phase substantially comprised of one or more natural or synthetically derived water soluble and/or water insoluble absorbents, characterised in that the continuous phase contains trans-polyoctenamer polymer, which material serves to elevate the shear strength of the composite. Because of its low melting point, compositions containing trans-poyloctenamer polymer are very easy to process. Formulations can be prepared that have only weakly adhesive properties, also formulations that are suitable as primary dressings for various hard-to-heal and chronic wounds. The pressure sensitive adhesive can also be combined with a non-adhesive, water impervious film, or other backing material, and can be used as the protective adhesive skin barrier component of ostomy pouches.
(FR) L'invention concerne une matière composite absorbant les fluides laquelle est autocollante et est constituée d'un mélange contenant une phase continue formée à partir d'une matrice adhésive autocollante, et une phase discontinue comprenant sensiblement un ou plusieurs absorbants hydrosolubles et/ou hydroinsolubles naturels obtenus par voie synthétique, caractérisée en ce que la phase continue contient un polymère trans-polyoctènamère, laquelle matière sert à élever la résistance au cisaillement du composite. Etant donné son faible point de fusion, les compositions contenant un polymère trans-polyoctènamère sont très faciles à mettre en oeuvre. Des formulations peuvent être préparées ne présentant que des propriétés faiblement adhésives, également des formulations adaptées en tant que pansements primaires pour diverses lésions difficiles à cicatriser et chroniques. L'adhésif autocollant peut aussi être combiné à un film non adhésif imperméable à l'eau, ou une autre matière de support, et il peut être utilisé en tant que constituant de barrière cutanée protecteur adhésif de poches pour stomie.
