Abstract

A process for obtaining polymer membranes from components of natural origin, which comprise a cross-linked matrix of biomaterials having physical and mechanical properties for controlled loading and release of substances, preferably by means of diffusion. The membranes obtained have high biodegradability. Said membranes are used as controlled-release dosage forms of substances beneficial to human health applied topically.
