Title
(EN) HYBRID CORE-SHELL MICROCAPSULES FOR ENCAPSULATING ACTIVE INGREDIENTS
(FR) MICROCAPSULES À NOYAU ET ENVELOPPE HYBRIDES POUR ENCAPSULER DES PRINCIPES ACTIFS
Abstract
(EN) It relates to a organic-inorganic core-shell microcapsule, wherein a) the shell forms a network which comprises: i) an anionic polymer which comprises a plurality of carboxylate or sulfonate groups, ii) a cationic polymer which comprises a plurality of quaternary ammoniumgroups, iii) an alkali metal silicate or a silicate precursor, and iv) a coupling agent which is an organosilane comprising at least a terminal group selected from a quaternary ammonium group, hydroxy, and carboxylate, and b) the core comprises one or more active ingredients in liquid form. It also relates to a process for its preparation, to a composition comprising the microcapsules and one or more excipients or carriers, and to their use as a disinfectant or for the delivery of active ingredients.
(FR) L'invention concerne une microcapsule à noyau et enveloppe inorganique-inorganique, dans laquelle a) l'enveloppe forme un réseau qui comprend : i) un polymère anionique qui comprend une pluralité de groupes carboxylate ou sulfonate, ii) un polymère cationique qui comprend une pluralité de groupes ammonium quaternaire,iii) un silicate de métal alcalin ou un précurseur de silicate, et iv) un agent de couplage qui est un organosilane comprenant au moins un groupe terminal choisi parmi un groupe ammonium quaternaire, un hydroxy et un carboxylate, et b) le noyau comprend un ou plusieurs ingrédients actifs sous forme liquide. L'invention concerne également un processus pour sa préparation, une composition comprenant les microcapsules et un ou plusieurs excipients ou supports, et leur utilisation en tant que désinfectant ou pour l'administration d'ingrédients actifs.
