Abstract
This invention relates to a denture adhesive composition comprising a lower alkyl vinyl ether-maleic acid, anhydride, or salt polymer or mixtures thereof, one or more metallic salts, nonionically associated with the lower alkyl vinyl ether-maleic acid, anhydride, or salt polymer, and at least one non-adhesive self-supporting layer. This invention may also comprise other adhesive components.
Claims17
A denture adhesive composition consisting essentially of:
- a) a lower alkyl vinyl ether-maleic acid, anhydride or salt polymer, and mixtures thereof;
- b) one non-adhesive self-supporting layer selected from the group consisting of polyester, polypropylene, nylon, rayon, cellulose acetate, cloth, fibrous fleece, paper, plastic, leather, synthetic fibers, natural fibers, and mixtures thereof;
- wherein the self-supporting layer provides integrity for the composition in the presence of water or saliva;
- c) one or more metallic salts, nonionically associated with the lower alkyl vinyl ether-maleic acid, anhydride or salt polymer;
- and
- d) one or more additional adhesives selected from the group consisting of natural gums, synthetic polymeric gums, karaya gum, guar gum, gelatin, algin, sodium alginate, tragacanth, chitosan, polyethylene glycol, acrylamide polymers, carbopol, polyvinyl alcohol, polyvinyl acetate, polyamines, polyquarternary compounds, polybutenes, silicones, polyvinylpyrrolidone, cationic polyacrylamide polymers, cellulose derivatives, and mixtures thereof.
A process for preparing a denture adhesive composition comprising the steps of:
- a) preparing a lower alkyl vinyl ether-maleic acid, anhydride or salt polymer;
- (b) combining the lower alkyl vinyl ether-maleic acid, anhydride or salt polymer with one or more metallic salts in a nonionic manner to form a mixture;
- (c) uniformly coating the mixture on at least one non-adhesive self-supporting layer(s) to form the denture adhesive composition;
- (d) mechanically softening the composition;
- and
- (e) cutting the composition as desired.
A bioadhesive composition for topical application to mucosal surfaces comprising:
- a) a lower alkyl vinyl ether-maleic acid, anhydride or salt polymer, or mixtures thereof;
- b) at least one non-adhesive self-supporting layer selected from the group consisting of polyester, polypropylene, nylon, rayon, cellulose acetate, cloth, fibrous fleece, paper, plastic, leather, synthetic fibers, natural fibers, and mixtures thereof;
- wherein the self-supporting layer provides integrity for the composition in the presence of water or saliva;
- c) one or more metallic salts, nonionically associated with the lower alkyl vinyl ether-maleic acid, anhydride or salt polymer;
- and
- d) a safe and effective amount of one or more therapeutic actives.
