Abstract
A denture adhesive composition is disclosed and comprises a polymeric activator in an amount of up to about 3 percent by weight based on the total weight of the denture adhesive composition; wherein the activator is selected from the group consisting of: poly(meth)acrylic acid, poly acrylic acid, polyitaconic acid, polycitraconic acid, and a monovalent alkali metal cation salt thereof. This composition exhibits enhanced adhesive performance and reduces oozing and incidence of food occlusion.
