Abstract

A foamable liquid denture cleanser and deodorant comprising surfactant, humectant, water and an appreciable amount of ethanol or isopropanol. Flavoring, sweetening, coloring, scenting and the like ingredients are optionally added. The cleanser is applied to dentures as an aerated foam from a conventional foam-dispensing device.

Claims

1. A method of cleansing dentures which comprises maintaining said dentures in contact with an aerated denture cleanser foam for a time sufficient to cleanse said dentures without brushing and subsequently removing any foam residue from the dentures, said foam consisting of a mixture of air and a foam-producing liquid composition comprising a pharmaceutically acceptable surfactant, an alcohol component selected from the group consisting of ethanol, isopropanol and mixtures thereof, a pharmaceutically acceptable humectant and water.

2. A method of cleansing dentures which comprises maintaining said dentures in contact with an aerated denture cleanser foam for a time sufficient to cleanse said dentures without brushing and subsequently removing any foam residue from the dentures, said foam consisting of a mixture of air and a foam-producing liquid composition comprising a pharmaceutically acceptable surfactant selected from the group consisting of sodium lauryl sulfate, sodium dodecyl benzene sulfonate, polysorbate 80, poloxomer 407 and mixtures thereof, an alcohol component selected from the group consisting of ethanol, ispropanol and mixtures thereof, a pharmaceutically acceptable humectant selected from the group consisting of glycerin, sorbitol, polyethylene glycol, propylene glycol and mixtures thereof, and water.

3. A method of cleansing dentures which comprises maintaining said dentures in contact with an aerated denture cleanser foam for a time sufficient to cleanse said dentures without brushing and subsequently removing any foam residue from the dentures, said foam consisting of a mixture of air and a foam-producing liquid composition comprising from about 1 to about 10 percent by weight of a pharmaceutically acceptable surfactant, from about 35 to about 70 percent by weight of an alcohol component selected from the group consisting of ethanol, isopropanol and mixtures thereof, from about 0.1 to about 10 percent by weight of a pharmaceutically acceptable humectant, from about 25 to about 60 percent by weight water and from zero to about 5 percent by weight of a pharmaceutically acceptable adjuvant selected from the group consisting of flavoring, coloring, scenting or sweetening agent and mixtures thereof.

4. The method of claim 3 wherein said surfactant is selected from the group consisting of sodium lauryl sulfate, sodium dodecyl benzene sulfonate, polysorbate 80, poloxomer 407 and mixtures thereof.

5. The method of claim 3 in said humectant is selected from the group consisting of glycerin, sorbitol, polyethylene glycol, propylene glycol and mixtures thereof.

6. A method of cleansing dentures which comprises maintaining said dentures in contact with an aerated denture cleanser foam for a time sufficient to cleanse said dentures without brushing and subsequently removing any foam residue from the dentures, said foam consisting of a mixture of air and a foam-producing liquid composition comprising from about 1 to about 10 percent by weight sodium lauryl sulfate, from about 35 to about 70 percent by weight ethanol, from about 0.1 to about 10 percent by weight glycerin, from about 25 to about 60 percent by weight water and from zero to about 5 percent by weight of a pharmaceutically acceptable adjuvant selected from the group consisting of flavoring, coloring, scenting or sweetening agent and mixtures thereof.

7. A method of cleansing dentures which comprises maintaining said dentures in contact with an aerated denture cleanse foam for a time sufficient to cleanse said dentures without brushing and subsequently removing any foam residue from the dentures, said foam consisting of a mixture of air and a foam-producing liquid composition comprising from about 2 to about 8 percent by weight of a pharmaceutically acceptable surfactant, from about 35 to about 50 percent by weight of an alcohol component selected from the group consisting of ethanol, isopropanol and mixtures thereof, from about 0.5 to about 5 percent by weight of a pharmaceutically acceptable humectant, from about 42 to about 60 percent by weight water and from about 0.3 to about 3 percent by weight of a pharmaceutically acceptable adjuvant selected from the group consisting of flavoring, coloring, scenting or sweetening agent and mixtures thereof.

8. The method of claim 7 said surfactant is selected from the group consisting of sodium lauryl sulfate, sodium dodecyl benzene sulfonate, polysorbate 80 poloxomer 407 and mixtures thereof.

9. The method of claim 7 wherein said humectant is selected from the group consisting of glycerin, sorbitol, polyethylene glycol, propylene glycol and mixtures thereof.

10. A method of cleansing dentures which comprises maintaining said dentures in contact with an aerated denture cleanser foam for a time sufficient to cleanse said dentures without brushing and subsequently removing any foam residue from the dentures, said foam consisting of a mixture of air and a foam-producing liquid composition comprising from about 2 to about 8 percent by weight sodium lauryl sulfate, from about 35 to about 50 percent by weight ethanol, from about 0.5 to about 5 percent by weight glycerin, from about 42 to about 60 percent by weight water and from 0.3 to about 3 percent by weight of a pharmaceutically acceptable adjuvant selected from the group consisting of flavoring, coloring, scenting or sweetening agent and mixtures thereof.

11. A method of cleansing dentures which comprises maintaining said dentures in contact with an aerated denture cleanser foam for a time sufficient to cleanse said dentures without brushing and subsequently removing any foam residue from the dentures, said foam consisting of a mixture of air and a foam-producing liquid composition having the relative proportionate formula:

about 5 grams sodium lauryl sulfate, about 45-47 mls 95% ethyl alcohol, about 1 gram glycerin, about 44-47 mls water and about 2.4 grams of a mixture of pharmaceutically acceptable flavoring and coloring agents.

12. A method of cleansing dentures which comprises maintaining said dentures in contact with an aerated denture cleanser foam for a time sufficient to cleanse said dentures without brushing and subsequently removing any foam residue from the dentures, said foam consisting of a mixture of air and a foam-producing liquid composition comprising the formulation:

about 5.0% w/w sodium lauryl sulfate, about 1.5% w/w poloxomer 407, about 29.26% w/w absolute alcohol, about 1% w/w glycerin, about 60.95% w/w water, about 0.5% w/w trisodium salt of ethylenediamine tetraacetic acid and about 1.79% w/w of a mixture of pharmaceutically acceptable flavoring, scenting and coloring agents.
