1. A method for lubricating the passage of a container along a conveyor, comprising: applying a lubricating emulsion to at least a portion of a container-contacting surface of the conveyor or to at least a portion of a conveyor-contacting surface of the container, the lubricating emulsion comprising
1. A method for lubricating the passage of a container along a conveyor, comprising: applying a lubricating emulsion to at least a portion of a container-contacting surface of the conveyor or to at least a portion of a conveyor-contacting surface of the container, the lubricating emulsion comprising:(a) 0.01% to about 0.35% of a water insoluble oil consisting of one or more unacidified fatty amine compound with viscosity greater than about 300 centipoise;(b) about 0 to about 0.35 wt-% emulsifier;(c) about 99.3 to about 99.99 wt-% water, inclusive of any hydrophilic diluents; and(d) alkali metal hydroxide; wherein the lubricating emulsion is applied for a period of time and not applied for a period of time and the ratio of not applied:applied time is between 2:1 and 32:1, and wherein the not applied time is about 12 minutes or less. 2. The method of claim 1, wherein the water insoluble oil has a viscosity of at least about 300 centipoise when measured with a parallel plate rheometer with 20 mm plate diameter and 0.25 mm plate separation at an integrated average shear rate of 5.9 sec−1. 3. The method of claim 1, wherein the unacidified fatty amine compound is selected from the group consisting of oleyl diamino propane, coco diamino propane, lauryl propyl diamine, dimethyl lauryl amine, and mixtures thereof. 4. The method of claim 1, wherein the water insoluble oil is emulsified with the emulsifier, and the resulting emulsion has a particle size from about 0.05 to about 5 microns. 5. The method of claim 1, wherein the applying comprises spraying the composition through a non-energized nozzle. 6. The method of claim 1, wherein applying comprises applying the lubricating emulsion for a first length of time and not applying it for a second length of time; wherein the ratio of the first length to the second length is about 1 to greater than or equal to about 10. 7. The method of claim 1, wherein the emulsion further comprises an additional component. 8. The method of claim 1, wherein the emulsion maintains a coefficient of friction of less than about 0.4 over the entire period of use. 9. The method of claim 1, wherein the container comprises polyethylene terephthalate, polyethylene naphthalate, polyethylene, polypropylene, paper board, glass, or metal. 10. A method for lubricating the passage of a container along a conveyor, comprising: applying a lubricant emulsion to at least a portion of a container-contacting surface of the conveyor or to at least a portion of a conveyor-contacting surface of the container, wherein the lubricant emulsion comprises:(a) an amine selected from the group consisting of oleyl diamino propane, coco diamino propane, lauryl propyl diamine, dimethyl lauryl amine, and mixtures thereof;(b) about 0.05 about 15 wt-% emulsifier; and(c) about 55 to about 97 wt-% water,wherein the lubricant emulsion has a pH of greater than 12, and wherein the lubricant emulsion is applied for a period of time and not applied for a period of time and the ratio of not applied to applied time is between 2:1 and 32:1. 11. A method for lubricating the passage of a container along a conveyor comprising: (a) providing a lubricant concentrate comprising i) a water insoluble oil consisting of one or more unacidified fatty amine compound with a viscosity greater than about 300 centipoise, wherein the unacidified fatty amine compound is selected from the group consisting of oleyl diamino propane, coco diamino propane, lauryl propyl diamine, dimethyl lauryl amine and mixtures thereof; andii) an emulsifier;(b) diluting the lubricant concentrate with water to form a lubricant use composition, the lubricant use composition comprising: i) the water insoluble oil;ii) from about 0 to about 0.35% of the emulsifier; andiii) from about 99.3 to about 99.99% water; 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 a conveyor-contacting surface of the container, wherein the lubricant use composition is applied for a period of time and not applied for a period of time and the ratio of not applied:applied time is between 2:1 and 32:1, and wherein the not applied time is about 12 minutes or less. 12. The method of claim 1, wherein the water insoluble oil has a viscosity greater than about 500 centipoise. 13. The method of claim 1, wherein the water insoluble oil has a viscosity greater than about 1000 centipoise. 14. The method of claim 10, wherein the amine has a viscosity greater than about 500 centipoise. 15. The method of claim 10, wherein the amine is emulsified with the emulsifier, and the resulting emulsion has a particle size from about 0.05 to about 5 microns. 16. The method of claim 10, wherein the applying comprises spraying the composition through a non-energized nozzle. 17. The method of claim 10, wherein the ratio of not applied to applied time is between 10:1 and 32:1. 18. The method of claim 10, wherein the emulsion maintains a coefficient of friction of less than about 0.4 over the entire period of use.
