(57) Abstract : 
Non - oil containing metalworking fluids, also known as synthetic metalworking fluids having an engineered particle size of greater 
than 120 nanometers upon dilution. The expansive particle size results in a substantial increase in lubricity, suitable or the heavy-duty 
operations previously attainable only with oil-containing products. Additionally this non-oil containing metal working lubricant 
optionally incorporates positive attributes of oil containing products, including excellent corrosion inhibition and heavy duty operation 
capable lubricity.
