Abstract
A method of lubricating conveyors with a lubricating concentrate formulated to contain about 0.5 wt-% to 90 wt-% of a fatty amide ethoxylate phosphate ester diluted to a use solution formulated to contain about 5 ppm to 1000 ppm of a fatty amide ethoxylate phosphate ester is described. The use solution is applied to an intended surface for lubrication. The lubricant can contain a variety of other chemical agents to provide additional desired properties including surfactants, chelating agents, sanitizing agents, and others. The lubricant concentrate or use solution is especially useful on conveyor systems with moving beverage containers such as glass, metal or plastic containers.
