Lubricating Greases From Olive Oil, Corn Oil and Palm Oil

The goal of the present work was to develop new lubricating greases from renewable resources, using calcium stearate soap as thickener agent dispersed in corn, olive and palm oils. The effects that temperature (in range 20 degrees C-60 degrees C) and concentration of the thickener agent (in range of 10%-30% wt) on the theological properties of these lubricating greases was studied. Also morphological and melting characterization was performed. Due to their consistency, theological behaviour, stability, non-toxicity and waterproof properties, the greases can be used for lubrication purposes in milder conditions such as sealing greases for food equipment or for chassis lubrication.
