<p>An inherently non-tacky chewing gum which does not adhere to dentures, fillings, or natural teeth is described. The chewing gum includes a base containing elastomers such as polyisobutylene, polyisoprene, isobutylene-isoprene copolymer or butadiene-styrene copolymer, present in from 5%-35%; hydrogenated or partially hydrogenated vegetable oils or animal fats, present in from 5%-50%; mineral adjuvants, present in from 5%-40%; and polyvinyl acetate which may be present in up to 55%; fatty acids which may be present in up to 20%, and mono and diglycerides of fatty acids which may be present in up to 10%, by weight of the base composition. The chewing gum of this invention eliminates conventional ingredients, and combinations of conventional ingredients found to exhibit adhesive characteristics. Such combinations which are eliminated in the compositions of this invention are natural gums, natural resins and rosin derivatives, and resins or waxes of petroleum origin; natural gums, natural or synthetic rubbers, and resins such as rosin derivatives, polyvinyl acetate, and polyterpenes; natural gums natural or synthetic rubbers, and waxes of petroleum or natural origin; and natural or synthetic rubbers, waxes, or resins.</p> |
