As society's awareness of environmental issues increases, industry has been forced to examine its processes and the chemicals it uses This is especially true in the metalworking fluid market where concerns have been raised over the potential environmental effects of certain chemicals used in metalworking fluids. In response to these concerns, the metalworking industry is demanding additives and finished fluids that are more environmentally acceptable and that have improved toxicological profiles. One approach to improving the environmental profile of metalworking fluids is the use of vegetable oils in place of mineral oils in soluble oil, semi-synthetic and synthetic fluid formulations. It is well known that vegetable oils have good lubricity properties. However, they are difficult to blend into water-based metalworking formulations. Typically, surfactants and coupling agents are needed to form a stable emulsion with vegetable oils. These components are expensive and can increase the cost of vegetable oil blends. Plus, they increase the potential foaming characteristics of the finished product.
