Particles of a substantially non-water-soluble biologically active substance charged with an ester charged with glyceryl as an electrostatic stabilizer giving the particles a zeta potential, in which the weight ratio between the active substance and the stabilizer is between 1: 1 and 400: 1, and the average particle diameter is between 1 nanometer and 10 micrometers. Said particles can be used as delivery systems. |
