Abstract

The present invention relates to a lubricating mixture, which contains glycerides of natural origin and fatty acid alkyl esters. The glycerides are at least partly mono and/or diglycerides which form a mass fraction of 10% in the mixture. In a temperature range from ≥10° C. to at least 15° C. the mixture has a liquid phase with a solid fraction of 1 vol. %, which is formed from a fraction of glycerides and/or fatty acid alkyl esters. The mixture can be formed entirely from renewable raw materials, has a high viscosity index and is particularly suitable as a lubricant for use in gearings, electric motors or internal combustion engines.
