| abstract |
The invention refers to a method for lubricating conveyor systems comprising the step of applying a lubricant composition comprising the following essential elements, a) one or more phosphoric acid esters, b) one or more ether carboxylates, c) one or more C6-C22 fatty acids, optionally ethoxylated with 1 to 20 moles of ethylene oxide, d) one or more C6-C22 fatty alcohols, optionally ethoxylated with 1 to 20 moles of ethylene oxide, e) a solvent, wherein the active matter concentration of said lubricant partially diluted composition ranges from 1 to 99% by weight. Said method is particularly preferred in conveyor systems for glass bottles, plastic bottles such as polyethylene terephtalate (PET) or polycarbonate (PC) bottles, cans, glass containers and cartons containers and similar items. Said conveyor systems can particularly be found in the foodstuff industry. The invention also provides a lubricant composition comprising with the components a) to d) as defined above, and e) a solvent other than water, wherein the active matter concentration of said lubricant composition, i.e. the concentration of components a) to d), ranges from 1 to 60% by weight, and wherein the concentration of solvent e) is in the range of 40 to 99 wt.%, each with respect to the total weight of the composition. |
