Abstract

PROCEDIMIENTO PARA LA PREPARACION DE CAPSULAS Y ENCAPSULACION DE SUSTANCIAS. ES UN NUEVO TIPO DE CAPSULAS QUE SE FORMA EN LA INTERACCION DE POLIMEROS CATIONICOS Y MOLECULAS ANFIFILICAS ANIONICAS. LA INVENCION CONSISTE EN HACER GOTEAR UNA SOLUCION DE QUITOSANO (POLIMERO POLISACARIDO CATIONICO DE PROCEDENCIA NATURAL) SOBRE UNA SOLUCION DE UN COMPUESTO ANFIFILICO ANIONICO A UNAS CONCENTRACIONES DETERMINADAS, FORMANDOSE EN EL SENO DE LA SOLUCION DEL COMPUESTO ANFIFILICO UNAS CAPSULAS ESFERICAS DEL TAMAÑO DE LA GOTA CONSTITUIDAS POR UNA MEMBRANA INSOLUBLE EN AGUA Y CUYO INTERIOR CONTIENE LA SOLUCION POLIMERICA. ESTAS CAPSULAS PERMITEN LA DIFUSION EN DOBLE SENTIDO DE SUSTANCIAS QUE PREVIAMENTE SE HAYAN DISUELTO BIEN EN LA SOLUCION DEL COMPUESTO ANFIFILICO O EN LA DE POLIMERO. SUS APLICACIONES MAS IMPORTANTES ESTAN EN EL CAMPO FARMACEUTICO, QUIMICO, ALIMENTARIO Y TEXTIL.PROCEDURE FOR THE PREPARATION OF CAPSULES AND ENCAPSULATION OF SUBSTANCES. IT IS A NEW TYPE OF CAPSULES FORMING IN THE INTERACTION OF CATIONIC POLYMERS AND ANIONIC ANPHYPHILIC MOLECULES. THE INVENTION CONSISTS OF DRIPPING A SOLUTION OF CHITOSAN (CATIONIC POLYACCHARIDE POLYMER OF NATURAL PROVENENCE) ON A SOLUTION OF AN ANPHYPHILIC COMPOUND ANIONIC TO A FEW CONCENTRATIONS, ESTABLISHED IN THE SITE OF THE ANIFIFAS CAPSULE COMPOSITE, FOR AN INSOLUBLE MEMBRANE IN WATER AND WHOSE INTERIOR CONTAINS THE POLYMERIC SOLUTION. THESE CAPSULES ALLOW THE DIFFERENT DIFFUSION OF SUBSTANCES THAT PREVIOUSLY HAD BEEN SOLVED WELL IN THE SOLUTION OF THE AMPHYPHILIC OR POLYMER COMPOUND. ITS MOST IMPORTANT APPLICATIONS ARE IN THE PHARMACEUTICAL, CHEMICAL, FOOD AND TEXTILE FIELDS.
