Novel non-aqueous water soluble food grade lubricant compositions comprising: (a) About 5% to about 50% of a polyalkylene glycol comprised of an ethylene oxide/propylene oxide copolymer, or polymer of propylene oxide, having molecular weight greater than 1,500; and (b) About 50% to about 95% of a polyethylene glycol having molecular weight of from about 200 to about 600; wherein said lubricating compositions have viscosities of about 28 to about 100% at 40° C. The novel non-aqueous water soluble food grade lubricant compositions are particularly useful in food processing and packaging equipment applications where low viscosity food grade lubricants with low pour points are desired, and in applications where there is a need for equipment and spill cleanup. These food grade lubricant compositions are also environmentally friendly due to their water solubility, rapid biodegradability, and low aquatic toxicity. |
