Abstract: The invention concerns the use of at least substantially water-insoluble dialkyl ethers of natural or synthetic mono- and/or polyhydric alcohols, the ethers being liquid at working temperatures, as the oil phase in agents for treating metal surfaces and in cooling lubricants. The invention also concerns agents containing at least such dialkyl ethers, corrosion inhibitors and emulsifiers. These dialkyl ethers are intended for use as mineral-oil substitutes.

Abstract: The concentration of the emulsion is monitored. To measure the concentration of the emulsion and/or its surfactant content and/or its current cleansing action, a bubble tensiometer operated with sufficiently constant gas flows is used to measure a value correlated to the dynamic surface tension. The measured values are compared with a predetermined reference value derived from a calibration for the cooling-lubricant emulsion in use. Depending on the results of the comparison, measures may be taken to refurbish the emulsion. The concentration of the emulsion is monitored continuously in an on-line process. The results can be recorded continuously. The process can also detect a diminution in the cleansing action of the cooling-lubricant emulsion when soilage builds up.
