Abstract
Se describen una sustancia activa encapsulada en celulosa regenerada y un metodo para encapsular una sustancia activa en una matriz de celulosa regenerada. La distribucion de la sustancia activa es preferiblemente homogenea sustancialmente dentro de la matriz de celulosa regenerada. La celulosa regenerada (i) tiene aproximadamente el mismo peso molecular que la celulosa original a partir de la cual se prepara, (ii) esta sustancialmente libre de grupos sustituyentes adicionados con relacion a la celulosa de inicio y tambien esta sustancialmente libre de productos de degradacion liquidos, ionicos, atrapados.
