Abstract

LA INVENCION SE REFIERE A UN PROCESO DE FABRICACION DE MICROPARTICULAS. ESTE PROCESO SE CARACTERIZA EN QUE SE PREPARA EN PRIMER LUGAR UNA EMULSION DE UNA SOLUCION DE UNA SUSTANCIA O DE UNA MEZCLA DE SUSTANCIAS EN UN LIQUIDO DISPERSANTE EN EL QUE DICHA SUSTANCIA O DICHA MEZCLA SON ESENCIALMENTE INSOLUBLES, Y A CONTINUACION SE INCORPORA A LA FASE DISPERSADA UN AGENTE QUIMICO, ESENCIALMENTE INSOLUBLE EN EL LIQUIDO DISPERSANTE DE MANERA A PROVOCAR EN EL SENO DE LA FASE DISPERSADA UNA REACCION QUIMICA O FISICOQUIMICA RESPONSABLE DE LA FORMACION DE MICROPARTICULAS QUE SE AISLAN A CONTINUACION.
