The passage of a container along a conveyor is lubricated by applying to the container or conveyor a composition comprising a water-miscible silicone material wherein the composition comprises a stoichiometric amount of an organic acid. The compatibility of the lubricating composition with polyethylene terephthalate is increased because of the presence of a stoichiometric amount of acid.

What is claimed is: 1. A method for lubricating the passage of a container along a conveyor, comprising a. providing a lubricant concentrate composition comprising i. from about 0.05% to about 20% of a water-miscible silicone material; and ii. one or more acid compounds in an amount sufficient to p
What is claimed is: 1. A method for lubricating the passage of a container along a conveyor, comprising a. providing a lubricant concentrate composition comprising i. from about 0.05% to about 20% of a water-miscible silicone material; and ii. one or more acid compounds in an amount sufficient to provide at least one equivalent of available, unneutralized acid for every two equivalents of alkalinity in water used to dilute the lubricant concentrate; b. diluting the lubricant concentrate with water in a ratio of one part lubricant concentrate to 100 to 1000 parts water to form a lubricant use composition; and c. applying the lubricant use composition to at least a portion of the container-contacting surface of the conveyor or to at least a portion of the conveyor-contacting surface of the container; wherein the pH of the lubricant use composition is less than about 6.4. 2. The method of claim 1, wherein the water used to dilute the lubricant concentrate composition comprises greater than about 50 ppm alkalinity as CaCO3. 3. The method of claim 1, wherein the silicone material is selected from the group consisting of silicone emulsion, finely divided silicone powder, and silicone surfactant. 4. The method of claim 1, wherein the lubricant concentrate composition further comprises one or more functional ingredients selected from the group of water-miscible lubricants, wetting agents, hydrophilic diluents, antimicrobial agents, stabilizing/coupling agents, detergents/ dispersing agents, anti-wear agents, viscosity modifiers, sequestrants, corrosion inhibitors and mixtures thereof. 5. The method of claim 1, wherein the container comprises one or more polymers selected from the group of polyethylene terephthalate, polyethylene naphthalate, and bisphenol A carbonate. 6. The method of claim 1, wherein the lubricant concentrate composition comprises one or more acid compounds in an amount sufficient to provide at least two equivalents of available, unneutralized acid for every two equivalents of alkalinity in water used to dilute the lubricant concentrate composition. 7. The method of claim 1, wherein the lubricant concentrate composition comprises one or more acid compounds in an amount sufficient to provide at least three equivalents of available, unneutralized acid for every two equivalents of alkalinity in water used to dilute the lubricant concentrate composition. 8. The method of claim 1, wherein the lubricant use composition is applied for a period of time and off for a period of time and the ratio of applied time to off time is at least 1: 1. 9. The method of claim 1, wherein the lubricant concentrate composition comprises one or more organic carboxylic acid compounds selected from the group consisting of acetic, lactic, succinic, glutaric, adipic, and citric acid and mixtures thereof. 10. A method for lubricating the passage of a container along a conveyor, comprising: a. providing a lubricant concentrate composition comprising i. from about 0.05% to about 20.0% of a water-miscible silicone material; and ii. greater than about 0.05 equivalents of acid per Kg of the lubricant concentrate composition before reaction with alkalinity in water used to prepare the lubricant use composition; b. diluting the lubricant concentration composition with water to form a lubricant use composition; and c. applying the lubricant use composition to at least a portion of the container-contacting surface of the conveyor or to at least a portion of the conveyor-contacting surface of the container; wherein the pH of the lubricant use composition is less than about 6.4. 11. The method of claim 10, wherein the water used to dilute the lubricant concentrate composition comprises greater than about 50 ppm alkalinity as CaCO3. 12. The method of claim 10, wherein the silicone material is selected from the group consisting of silicone emulsion, finely divided silicone powder, and silicone surfactant. 13. The method of claim 10, wherein the lubricant composition further comprises one or more functional ingredients selected from the group of water-miscible lubricants, wetting agents, hydrophilic diluents, antimicrobial agents, stabilizing/coupling agents, detergents/ dispersing agents, anti-wear agents, viscosity modifiers, sequestrants, corrosion inhibitors and mixtures thereof. 14. The method of claim 10, wherein the container comprises one or more polymers selected from the group of polyethylene terephthalate, polyethylene naphthalate, and bisphenol A carbonate. 15. The method of claim 10, wherein the lubricant concentrate composition comprises greater than about 0.1 equivalents of acid per Kg of the concentrate composition before reaction with alkalinity in water used to prepare the use composition. 16. The method of claim 10, wherein the lubricant concentrate composition comprises greater than about 0.15 equivalents of acid per Kg of the concentrate composition before reaction with alkalinity in water used to prepare the use composition. 17. The method of claim 10, wherein the lubricant composition is applied for a period of time and off for a period of time and the ratio of applied time to off time is at least 1:1. 18. The method of claim 10, wherein the lubricant concentrate composition comprises one or more organic carboxylic acid compounds selected from the group consisting of consisting of acetic, lactic, succinic, glutaric, adipic, and citric acid and mixtures thereof. 19. A lubricant concentrate composition comprising from about 0.05 to about 20% of a water-miscible silicone material selected from the group consisting of silicone emulsion, finely divided silicone powder, and silicone surfactant and greater than about 0.05 equivalents of unneutralized acid per kg of the concentrate composition wherein the acid is selected from the group consisting of consisting of acetic, lactic, succinic, glutaric, adipic, and citric acid and mixtures thereof wherein the amount of unneutralized acid in the concentrate composition is sufficient to provide a pH of less than about 6.4 when in use. 20. The lubricant concentrate composition of claim 19, comprising greater than about 0.1 equivalents of unneutralized acid per kg of the concentrate composition. 21. The lubricant concentrate composition of claim 20 comprising greater than about 0.15 equivalents of unneutralized acid per kg of the concentrate composition.
