    摘要: A denture adhesive base composition comprises a substantially anhydrous mixture of a cationic derivatives of guar gum, a mixed Na/Ca salt of methyl vinyl ether-maleic anhydride and sodium carboxymethylcellulose. A denture adhesive composition including this base composition is provided, as well as a method for formulating the novel adhesives of the invention. Upon hydration, the denture adhesives of the invention form denture adhesive compositions exhibiting improved denture holding and adhesive duration properties.
