Title (EN) NOVEL POLYMER GEL NETWORKS AND METHODS OF USE
(FR) NOUVEAUX RESEAUX DE GEL POLYMERE ET PROCEDES D'UTILISATION
Abstract:
(EN) A cross-linked, responsive polymer gel network comprising polymer chains interconnected by way of a multifunctional cross-linker is described. The polymer chains and cross-linker have a known acceptable toxicological profile (KATP). Pathways for determining if a particular material has a KATP are provided. The polymer chains should be a component part of a product that is considered in compliance with applicable governmental agency regulations as acceptable for a use selected from the group consisting of a food use, a cosmetic use, and an animal drug delivery use. Moreover, the cross-linker also should be a component part of a product that is considered in compliance with applicable governmental agency regulations as acceptable for a use selected from the group consisting of a food use, a cosmetic use, and an animal drug delivery use.
(FR) Réseau de gel polymère réticulé et sensible, comprenant des chaînes polymères reliées par l'intermédiaire d'un agent de réticulation multifonctionnel. Les chaînes polymères et l'agent de réticulation présentent un profil toxicologique connu et acceptable (KATP). On décrit des procédés permettant de déterminer si une matière donnée présente un profil toxicologique connu et acceptable. Les chaînes polymères, ainsi que l'agent de réticulation, devraient être un composant d'un produit qui est considéré comme satisfaisant aux règlements en vigueur émanant d'agences gouvernementales et régissant l'utilisation de ce produit dans les domaines relatifs à l'alimentation, à la cosmétique et à l'administration de médicaments aux animaux.
