Water-miscible cooling lubricants consist largely of base oils, emulsifiers and additives. Until now, it was assumed that the base oil content was decisive for the lubricating performance of a product. Products with a high base oil content were and are said to have a high lubricating performance. However, a higher base oil content makes it more difficult to distribute the oil droplets in the emulsion, which affects the flow behavior of the cooling lubricants. Coolants with a high base oil content and good lubricating performance have therefore always had relatively poor drainage behavior. This increases the consumption of cooling lubricant, as larger oil droplets also result in more cooling lubricant being discharged.

The new esgemo L-E-T (Lubrifying Emulsifier Technology) has made it possible to add lubricating components to the cooling lubricant in the form of special emulsifiers. This reduces the mineral oil content of the concentrate and at the same time improves the lubricating performance of the products. Products based on L-E-T are also more finely dispersed and thus lead to better drainage behavior and consequently to lower consumption and cleaner parts and machines. esgemo L-E-T now combines excellent lubrication performance with outstanding drainage behavior and very good rinsing performance.
