Abstract
Disclosed are improved denture adhesive compositions containing a hydrophobically modified water-soluble polymer alone or admixed with an alkali metal salt of carboxymethyl cellulose having a D.S. of at least 0.3. Hydrophobically modified hydroxyalkyl celluloses and copolymers of ethylene oxide and long chain epoxyalkanes are preferred as the water-soluble polymer.
Claims13
A denture adhesive composition consisting essentially of (a) from about 5% to about 50% of a hydrophobically modified water-soluble polymer selected from the group consisting of a hydrophobically modified cellulose ether wherein the cellulose ether is substituted with a hydrocarbon radical having 8 to 25 carbon atoms in an amount from about 0.2 weight percent to about the amount which renders the cellulose ether less than 1% by weight soluble in water and a copolymer of ethylene oxide and at least one long chain epoxyalkane having 8 to 25 carbon atoms;
- (b) from about 35% to about 85% of petrolatum;
- and (c) 0% to about 15% of a material selected from the group consisting of mineral oil and mineral oil admixed with a polyethylene.
