Claim 1
Independent Claim
57 words
A base for mucosal and denture adhesive pastes comprising, a solid swelling agent which is swellable only in water and is dispersed in a colloidal solution of an organic second swelling agent in a water-soluble, physiologically tolerated organic solvent, wherein the organic second swelling agent is swellable in water and is an ionic swelling agent xanthum gum.
Claim 2
Dependent Claim
57 words
