ABSTRACT:
An aqueous dispersion of colloidal size particles of a water-insoluble, polysaccharide derivative such as ethylcellulose is prepared by grinding the water-insoluble, polysaccharide derivative in the presence of water. A suspending agent is optionally employed to increase grinding efficiency and to form a stable suspension of the colloidal size particles.
