D-optimal mixture design: Formulation development, mechanical characterization, and optimization of curcumin chewing gums using oppanol® B 12 elastomer as a gum-base

Curcumin (CUR) chewing gums have potential therapeutic benefits to head and neck cancer patients. The objective of this work was to develop medicated chewing gums (MCGs) with high CUR loading and desirable mastication properties. This was accomplished by evaluating the effect of five gum ingredients: (X1) polyisobutene, (X2) polyvinyl acetate, (X3) wood rosin, (X4) wax, and (X5) CUR on the mechanical properties of the MCGs using a 25-run,...
