Abstract

METODO PARA AUMENTAR LA ESTABILIDAD DE LAS NANOCAPSULAS DURANTE SU ALMACENAMIENTO. COMPRENDE: INCORPORAR UN AGENTE CRIOPROTECTOR EN UNA DISPERSION ACUOSA DE LAS CITADAS NANOCAPSULAS MANTENIENDO UNA SUAVE AGITACION HASTA SU TOTAL DISOLUCION, SEGUIDAMENTE, SOMETER A CONGELACION LA DISPERSION ASI OBTENIDA A UNA TEMPERATURA NO INFERIOR A LOS -40 C DURANTE 2 A 4 HORAS APROXIMADAMENTE Y, FINALMENTE, ELIMINAR EL AGUA CALENTANDO PROGRESIVAMENTE HASTA UNA TEMPERATURA DE 35 C APROXIMADAMENTE Y A PRESION REDUCIDA, CON LO QUE SE OBTIENE UN PRODUCTO LIOFILIZADO ESTABLE, QUE PUEDE RECONSTITUIRSE CONVENIENTEMENTE AÑADIENDOLE AGUA O UNA SOLUCION ACUOSA MAS COMPLEJA. LAS NANOCAPSULAS TIENEN APLICACION EN MEDICINA, FARMACIA, COSMETICA, INDUSTRIA QUIMICA, AGRICULTURA, VETERINARIA, ETC.
