Abstract

PROCEDIMIENTO PARA LA ESTABILIZACION DE PARTICULAS MICELARES Y PARA AUMENTAR SU DURACION EN ESTADO PREPARADO. CONSISTE EN SUSPENDER LAS PARTICULAS EN UNA MATRIZ DE GEL POLIMERA PARA FORMAR UNA SUPERFICIE DE GEL PROTECTORA ALREDEDOR DE DICHAS PARTICULAS, SIENDO DICHA MATRIZ CAPAZ DE TRANSFORMARSE EN UN FLUIDO, TRANSFORMANDO LA SUPERFICIE DE GEL PROTECTORA EN UNA SUSPENSION ACUOSA. EL TAMAÑO Y PROPIEDADES DE LAS PARTICULAS MICERALES PERMANECEN CON EL MISMO TAMAÑO A LO LARGO DEL ALMACENAMIENTO, MIENTRAS EL GEL PERMANEZCA EN SU ESTADO SOLIDO. SIN EMBARGO, A TEMPERATURA AMBIENTE O SUPERIOR, EL GEL SE FUNDE Y LA VESICULA U OTRA PARTICULA CUALQUIERA VUELVE A SU FORMA ORIGINAL EN SUSPENSION EN UN MEDIO ACUOSO. DE APLICACION COMO PORTADORES PARA AGENTES FARMACEUTICAS.
