ABSTRACT:
A process for modifying an unsaturated polyol fatty acid ester stock, such as an unsaturated triacylglycerol oil, to enhance its fluidity and/or oxidative stability is provided. The method includes reacting the unsaturated polyol fatty acid ester stock with cyclopropanating agent. Lubricants containing a modified unsaturated polyol fatty acid ester and methods for their production and use are also provided.
