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° C. to about 8° C. 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. The present invention also provides a method for enhancing stability as a solution or a dispersion of a composition containing a surfactant and a carrier, involving incorporating a phosphonium compound into the composition.
A composition consisting essentially of a surfactant, tetrakis(hydroxymethyl)phosphonium sulfate, a neutralizing agent, a chelating agent, and a carrier;
A composition consisting essentially of about 10 wt. % to about 70 wt. % of deionized water;
A composition consisting essentially of a neutralizing agent, a chelating agent, at least 1 wt. % of a surfactant, at least 0.1 wt. % of tetrakis(hydroxymethyl)phosphonium sulfate, and at least 5 wt. % of a carrier.
