  • DEGRADABLE CHEWING GUM AND METHOD OF MAKING THE SAME
    Publication number: 20140322385
    Abstract: A degradable chewing gum composition including about 5 to about 90 weight percent of a water-insoluble gum base and about 0.1 to about 15 weight percent of an alternating copolymer of maleic anhydride and a C2-C10 alkene is described. The alternating copolymer facilitates environmental degradation of improperly disposed chewing gum cuds. Also described is a method of preparing the chewing gum composition.

  • HYDROPHILIC GUM BASE
    Publication number: 20140161739
    Abstract: A gum base comprising: a) a hydrophilic precursor component comprising hydrolysable units; and b) a copolymer of a hydrophilic monomer with a second monomer selected from vinyl acetate, isobutylene, isoprene, butyl rubber or styrene butadiene. This chewing gum base contributes to the ability of the chewing gum compositions and chewing gum products to degrade over time after chewing by imparting the chewing gum with increased hydrophilic properties.
