Abstract

DISPOSITIVOS DE DISTRIBUCION DE MEMBRANA LIQUIDA SOPORTADA QUE LIBERAN UN AGENTE BENEFICIAL PARA UN ENTORNO ACUOSO SIGUIENDO LA EXPOSICION A UN ACTIVADOR AMBIENTAL. UNA MEMBRANA DE SOPORTE HIDROFOBICO MICROPOROSO RODEA, AL MENOS PARCIALMENTE, A UNA FORMULACION HIDROFILICA QUE CONTIENE AL AGENTE BENEFICIOSO. UN LIQUIDO HIDROFOBICO ESTA SUJETO DENTRO DE LA MEMBRANA DE SOPORTE MICROPOROSO A TRAVES DE CAPILARIDAD Y EL LIQUIDO HIDROFOBICO ES SUSTANCIALMENTE PERMEABLE AL ENTORNO ACUOSO Y A LA FORMULACION HIROFILICA QUE CONTIENE AL AGENTE BENEFICIOSO. EL LIQUIDO HIDROFOBICO ARRASTRADO LLEGA A SER SUSTANCIALMENTE PERMEABLE AL ENTORNO ACUOSO EN LA EXPOSICION A UN ACTIVADOR AMBIENTAL COMO POR EJEMPLO UNA ENZIMA, Y EL AGENTE BENEFICIOSO ES CONSIGUIENTEMENTE LIBERADO.
