All lubricants leak somewhat from their machinery. While this fairly innocuous in most applications, they may contaminate the food in the food-processing industry. The challenge is therefore to find a lubricant that meets its mechanical requirements and also the health standards. In recent years, due to the global establishment and implementation of Hazard Analysis and Critical Control Points (HACCP) and Good Manufacturing Practice (GMP), the food-processing and pharmaceutical industries have been looking for good-grade lubricants. Food- grade lubricants must perform the same technical functions as any other lubricant, i.e. provide protection against wear, friction, corrosion and oxidation, dissipate heat and transfer power, be compatible with rubber and other sealing materials, and also, in some cases, to provide a sealing effect. Food-grade lubricants, formulated in compliance with the Code of Federal Regulations (CFR), Title 21, Section 178.3570 and other sections referenced therein of the National Sanitation Foundation (NSF) Authhorization Programme are catagorized under code H1 as lubricants intended for use in food-processing areas with incidental food contact.
