Beschreibung
Zusammenfassung:	Use of degraded or reduced molecular weight polymers in encapsulation is disclosed. Short chain polysaccharide derivatives such as ionic cellulose derivative hydrolyzates are used in forming capsules by combining the short chain polysaccharide derivatives with another polymer. Substances designed to be encapsulated serve as nuclei around which coacervate droplets are formed. The short chain charged polymer includes degradation products of polysaccharide derivatives having an average degree of polymerization in the range of 3 to about 500. Methods of using capsules for delivering or storage of oils, and other substances are disclosed. The invention also discloses use of capsules in food, feed, pharmaceutical, cosmetic and personal care products and in the coating of paper with microscopic rupturable capsules containing printing fluid.
