Abstract: Chewing gum base including i. 1 to 99% by weight of a polymeric material which has a straight or branched chain carbon-carbon backbone and a multiplicity of side chains, and is substantially insoluble in water; ii. from 0-6% by weight wax; iii. up to 99% by weight of an elastomeric material different to the polymeric material; and iv. 0 to 20% by weight of an elastomer plasticiser; in which the total amount of polymeric material and elastomeric material is at least 10% by weight of the chewing gum base. A chewing gum composition including this chewing gum base, and methods of manufacture, are also provided.

Abstract: The present invention provides a chewing gum composition comprising a chewing gum base, a biologically active ingredient, a polymeric material and one or more sweetening and flavouring agents, wherein the polymeric material is amphiphilic, has a straight or branched chain carbon-carbon backbone and a multiplicity of side chains attached to the backbone. A method of making the chewing gum composition is also provided.
