Abstract

Disclosed are denture adhesive compositions possessing improved aesthetics and comprising a component which provides for easy removal of the adhesive from the denture and a hydrophilic powder.

Claims

1. A denture adhesive composition which adheres to dentures and oral tissue comprising a mixture of:

(a) from about 8% to 90% of a hydrophilic powder selected from the group consisting of mixed partial salts of alkyl vinyl ether maleic anhydride copolymers (AVE/MA), sodium carboxymethylcellulose (CMC), polyethylene glycol (PEG), sodium alginate, hydroxyethylcellulose (HEC), chitosan, acid form of alkyl vinyl ether maleic anhydride copolymer, carbopol polymers, polyvinyl alcohol, polyamines, polyquarternary compounds, and mixtures thereof; and

(b) from about 10% to 92% of a part silicone RTV liquid that cures to form a peelable solid upon mixing the 2 parts.

2. The composition of claim 1 wherein component (a) comprises mixed partial salts of AVE/MA, CMC, PEO, karaya gum and/or HEC and component (b) is a 1- or 2-part silicone RTV that cures by 2-part mixing and/or exposure to saliva/water.

3. The composition of claim 2 wherein component (b) is an addition cured 2-part silicone RTV wherein part 1 is a blend of vinyl functional silicone polymers, and a platinum catalyst and/or silica and/or inhibitors;

and part 2 is a blend of vinyl functional silicone polymers, and a hydride functional siloxanes and/or silica.

4. The composition of claim 2 wherein component (b) is an addition cured 2-part silicone RTV wherein part 1 is a blend of vinyl -terminated polydimethyl siloxane, and a platinum-divinyltetramethyldisiloxane complex catalyst and/or silica;

and part 2 is a blend of vinyl-terminated polydimethylsiloxane, and a polydimethylsiloxane polymer containing Si-H groups and/or silica.

5. The composition of claim 2 wherein component (b) is a 2-part condensation cured silicone RTV wherein part 1 is a blend of silanol-terminated silicone polymers, and alkoxy functional silicon compounds, and silica and/or diatomaceous earth;

and part 2 is a tin and/or zinc catalyst.

6. The composition of claim 2 wherein component (b) is a 2-part condensation cured silicone RTV wherein part 1 is a blend of silanol-terminated silicone polymers, and hydride functional siloxanes, and silica and/or diatomaceous earth;

and part 2 is a tin and/or zinc catalyst.

7. The composition of claim 2 wherein component (b) is a 1-part silicone RTV that cures by exposure to saliva/water with or without a basic additive to neutralize the acidic by-products.

8. The composition of claim 2 wherein component (b) is converted to a 1-part system via microencapsulation.

12. The composition of claim 1 which further comprises from about 0.01% to about 30% of menthol, menthyl lactate, peppermint oil, spearmint oil, leaf alcohol, paramenthane carboxyamides, dyes and colorants, antibacterial additives and mixtures thereof.

13. The composition of claim 1 which in addition contains a silicone fluid, grease, gum, resin or mixtures thereof as a component of the total composition.

14. The composition of claim 1 wherein (b) is a silicone fluid, grease, gum, resin or mixtures thereof.

15. The composition of claim 1 where (b) is a 1- or 2-part silicone RTV liquid modified to contain carboxyl, hydroxyl and/or amino functional groups.

9. A denture adhesive composition which adheres to dentures and oral tissue comprising a mixture of:

(a) from about 8% to 90% of a hydrophilic powder selected from the group consisting of AVE/MA (neutralized with calcium, zinc, sodium, strontium, iron and/or magnesium), CMC, HEC and mixtures thereof; and

(b) from about 10% to 92% of a 2-part silicone RTV liquid that cures to form a peelable solid upon mixing the two parts or a 1-part silicone RTV liquid that cures to form a peelable solid upon exposure to moisture/saliva.

10. The composition of claim 9 wherein (a) is a mixed partial salt of AVE/MA copolymer (neutralized with calcium, zinc and/or sodium) and/or CMC.

11. The composition of claim 9 wherein (b) is a 2-part silicone RTV.

16. A denture adhesive composition which adheres to dentures and oral tissue comprising a mixture of:

(a) from about 8% to 90% of a hydrophilic powder selected from the group consisting of mixed partial salts of alkyl vinyl ether maleic anhydride copolymers (AVE/MAX) sodium carboxymethylcellulose (CMC), polyethylene glycol sodium alginate, hydroxyethylcellulose (HEC), chitosan, acid form of alkyl vinyl ether maleic anhydride copolymer, carbopol polymers, polyvinyl alcohol, polyamines, polyquarternary compounds, and mixtures thereof; and

(b) from about 10% to 92% of a 1-part silicone RTV liquid that cures to form a peelable solid upon exposure to saliva/water.
