Calcium sulfonate complex grease is recognized as an excellent technology for grease applications where heat, water, and high or shock loads exist. Its inherent properties are well known and include excellent corrosion resistance, low wear and high EP, high dropping point, and excellent mechanical stability, even in the presence of water. Calcium sulfonate complex grease has recently been approved for use as an incidental food contact grease (H1), and these inherent properties will provide improved lubrication of food machinery, particularly where heat and water are present. This paper will review the technology and will examine its performance as compared to other food machinery grease technologies.
