Abstract
The present invention relates to denture adhesive composition that can be dispensed from a tube, syringe and/or a pump comprising a safe and effective adhesive amount of a denture adhesive component; and a safe and effective amount of a water insoluble component selected from the group consisting of a water insoluble thermoplastic component, a water insoluble liquid component, and mixtures thereof; wherein the composition comprises a normalized ooze amount of about 0.001% to about 40%, or a ooze ratio from about 0.001 to about 0.7.
Claims32
A denture adhesive composition comprising:
- a) a safe and effective adhesive amount of a denture adhesive component;
- and
- b) a safe and effective amount of a water insoluble component selected from the group consisting of a water insoluble thermoplastic component, a water insoluble liquid component, and mixtures thereof;
- wherein the composition comprises a normalized ooze amount of about 0% to about 40%, or a ooze ratio of from about 0 to about 0.7;
- wherein the denture adhesive composition can be dispensed from a container selected from the group consisting of a syringe, a tube, and a pump.
A denture adhesive article comprising:
- a) a safe and effective adhesive amount of a denture adhesive component;
- and
- b) a safe and effective amount of a water insoluble component selected from the group consisting of a water insoluble thermoplastic component, a water insoluble liquid component, and mixtures thereof;
- wherein the article is bioerodible;
- and comprises at least one layer;
- and the composition comprises a normalized ooze amount of about 0% to about 40%, or a ooze ratio of from about 0 to about 0.7;
- and when the article comprises 3 layers and has a denture adhesive component selected from the group consisting of sodium carboxymethylcellulose, polyethylene oxide, polyvinyl alcohol, and mixtures thereof, then at least one outside layer contains a water insoluble thermoplastic component, or at least one layer further comprises an additional denture adhesive component selected from the group consisting of AVE/MA, salts of AVE/MA, mixed salts of AVE/MA, starch derivatives, carrageenan, cellulose derivatives, polymeric acids, polymeric salts, polyhydroxy compounds, and mixtures thereof;
- wherein the additional denture adhesive component excludes sodium carboxymethylcellulose, polyethylene oxide, polyvinyl alcohol, and mixtures thereof.
