Ortrol is a brownish-yellow emulsion of high quality lubricating oils that dissolves easily and without foaming in water to give a lubricating fluid that is protected for a long time from the presence of microorganisms with special preservative additives. On machines that process metal (cutters, milling machines, lathes, lathes, reconditioners, etc.), dissolve 1 part of Ortrol in 5-10 parts of water.
