Abstract
An adhesive agent for dentures consists of a spreadable compound with an alginate, a polyvinyl acetate, a carboxymethyl cellulose and an emulsifier. In order to obtain a lasting effect, unchanging spreadability and long-term durability, the compound consists of a mixture of a modified mixture of carboxymethyl cellulose and sodium alginate with the polyvinyl acetate, an anionic water- and alcohol-soluble cellulose ether, a gel, a neutral oil and an organically modified montmorillonite as the emulsifier and stabilizer, as well as of an alcohol solvent.
Claims10
An adhesive agent for dentures consisting of a spreadable compound of
- (a) 75 parts of a mixture of carboxymethyl cellulose and sodium alginate, and
- (b) 25 parts of an alcoholic solution of polyvinyl acetate containing an anionic water- and alcohol-soluble cellulose ether and an emulsifying and stabilizing gel comprised of a neutral oil and an organically modified montmorillonite.
A process of producing an adhesive agent for dentures consisting of a spreadable compound, which comprises the steps of
- (a) preparing a solution of polyvinyl acetate in an alcoholic solvent, stirring an anionic water- and alcohol-soluble cellulose ether into the alcoholic polyvinyl acetate solution, storing the resultant solution and finally stirring an emulsifier and stabilizer gel comprised of a neutral oil and an organically modified montmorillonite into the stored solution to obtain a first mixture,
- (b) mixing 75 parts of a mixture of carboxymethyl cellulose and sodium alginate with 25 parts of the first mixture, and
- (c) kneading the mixtures until a paste-like, spreadable compound is obtained.
