  • Stable dispersion of liquid hydrophilic and oleophilic phases in a conveyor lubricant
    Patent number: 6509302
    Abstract: We have found that a clear, stable microemulsion can be used during container transport operations during which the container is contacted with a transparent dispersion of hydrophilic and oleophilic materials. A process for lubricating a container, such as a beverage container, or a conveyor for containers, by applying to the container or conveyor, a thin continuous, substantially non-dripping layer of a transparent dispersed liquid lubricant. The process provides many advantages compared to the use of a conventional lubricant diluted with water.
