Natural fatty oils such as palm oil, castor oil, rapeseed oil, soybean oil, sunflower oil, lard, and sperm oil have been used as lubricants for years. They are normally called triglycerides of more or less unsaturated fatty esters. This type of base is "biodegradable" and, compare to mineral oils, show excellent tribological properties (low friction coefficient and good wear protection). However, their range of use is limited by lower stability against thermal oxidative and partly inferior cold flow properties, specifically in lubricating grease. Their limits can be improved gradually either with appropriate additives or with chemically modified process. In this particular work, an optimal palm oil-based grease blending formula is proposed utilization of the statistical design of experiments (DOE). Input variables are palm oil-based grease structures (% of palm oil, % of thickener and % of additives), type and percentage of each specific additives.
