Abstract

The present invention provides a beverage surfactant composition that includes a surfactant, a phosphonium compound, and a carrier; wherein the beverage surfactant composition exhibits stability as a solution or as a dispersion at a temperature of about 0 EC to about 8 EC. The present invention also provides a container or a conveyor for a container having a surface that is at least partially coated with the composition. The present invention also provides a process for lubricating a container that includes contacting at least a portion of a surface of the container and the composition together. The present invention also provides a process for lubricating a conveyor that includes contacting at least a portion of a surface of the conveyor and the composition together.

Claims (16)

1. A composition comprising a surfactant, a phosphonium compound selected from the group consisting of tetrakis(hydroxymethyl) phosphonium sulfate, tetrakis(hydroxymethyl) phosphonium phosphate, tetrakis(hydroxymethyl) phosphonium chloride, and combinations thereof, and a carrier; the phosphonium compound is present in the composition at a sufficient quantity such that the composition exhibits stability as a solution at a temperature of about 0° C. to about 8° C.

2. The composition of claim 1 wherein the surfactant is present in about 2 wt. % to about 40 wt. % of the composition.

3. The composition of claim 1 wherein the phosphonium compound is present in about 1 wt. % to about 10 wt. % of the composition.

4. The composition of claim 1 wherein the carrier is water.

5. The composition of claim 1 wherein the carrier is present in about 10 wt. % to about 95 wt. % of the composition.

6. The composition of claim 1 , wherein the surfactant is an anionic surfactant, a cationic surfactant, a nonionic surfactant, an amphoteric surfactant, or a combination thereof.

7. The composition of claim 6 wherein the surfactant comprises an anionic surfactant that is a phosphate ester.

8. The composition of claim 6 wherein the surfactant comprises a cationic surfactant that is a quaternary ammonium salt.

9. The composition of claim 6 wherein the surfactant comprises a nonionic surfactant that is an alcohol alkoxylate.

10. The composition of claim 6 wherein the surfactant comprises an amphoteric surfactant that is a fatty amine derivative.

11. The composition of claim 1 wherein the composition further comprises a neutralizing agent.

12. The composition of claim 11 wherein the neutralizing agent is present in an amount such that the pH of the composition is between about 4.5 and about 9.5.

13. The composition of claim 11 wherein the neutralizing agent is an alkaline metal hydroxide, an alkyl amine, an organic acid, an inorganic acid, or any combination thereof.

14. The composition of claim 1 further comprising a chelating agent.

15. The composition of claim 14 wherein the chelating agent is present in about 1 wt. % to about 10 wt. % of the composition.

16. The composition of claim 14 wherein the chelating agent is ethylenediaminetetraacetic acid, or a suitable salt thereof.
