Abstract

Un método para la liberación controlada en agua de un compuesto activo, en especial de un compuesto clorante y bactericida, seleccionado del grupo constituido por detergentes, blanqueadores, pesticidas, agentes colorantes, bactericidas, agentes químicos y colorantes con un mínimo de solubilidad en agua o un medio acuoso y presentando el citado medio una temperatura máxima de 60ºC, caracterizado porque comprende, obtener una bolsa sellada de alcohol polivinílico insoluble en agua fría y permeable al compuesto activo por laminación en forma de película de un alcohol polivinílico de tipo sustancialmente lineal e hidrolizado por lo menos en un 99% y con un grado de hinchamiento en agua de un 120 a un 200% teniendo el pH de la película un valor entre 2,5 y 10, opcionalmente próximo a pH neutro, en el interior de cuya bolsa se aloja una cantidad efectiva del citado compuesto activo, manteniendo una relación máxima de peso de este último respecto al volumen de la bolsa de 800 kg/m3; sumergir la bolsa sellada en un medio acuoso y producir el hinchamiento de la película de alcohol polivinílico, provocando un flujo osmótico del medio acuoso hacia el interior de la bolsa, que disuelve el compuesto activo y forma una solución acuosa de este último con un pH ente 2,5 y 10, preferentemente de 4 a 10, cuyo flujo se equilibra con la presión osmótica hacia fuera de dicha solución que difunde a través de la película hinchada, liberando el citado compuesto activo en dicho medio acuoso.
