A fluid composition comprises a triglyceride, having at least one alpha-branched fatty acid residue, wherein each alpha-branched fatty acid residue comprises at least one saturated or mono-unsaturated alkyl chain having a total number of carbon atoms ranging from 12 to 20, and wherein the triglyceride has at least one of (a) a flash point of at least 185&#xb0; C., (b) a fire point of at least 230&#xb0; C., (c) a pour point of &#x2212;25&#xb0; C. or lower, or (d) a combination thereof. The fluid composition may be useful, for example, as a dielectric fluid and/or as a heat transfer fluid in transformers and other electrical device applications.

Branched triglyceride-based fluids useful for dielectric and/or heat transfer applications

A vegetable-based dielectric fluid comprising in weight percent of triglycerides based on the weight of the fluid: A. Greater than 0 to 100% of at least one of C14:1 or C16:1 fatty acids; and at least one of: B. No more than (&#x2266;) 10% of C18:1 fatty acids; C. No more than (&#x2266;) 12% of one or more polyunsaturated fatty acids; and D. No more than (&#x2266;) 7% of one or more saturated fatty acids. The dielectric fluid is a useful transformer oil.

Non-oleic triglyceride based, low viscosity, high flash point dielectric fluids

A dielectric fluid comprising in weight percent based on the weight of the composition: A. 30 to 70% C18:1 fatty acids; B. 10 to 55% of a mixture of C8 and C10 fatty acids in which the mixture comprises 50 to 70 wt %, based on the weight of the mixture, of C8 fatty acids; C. No more than 13% polyunsaturated fatty acids; and D. No more than 7% of saturated fatty acids of which each contains at least 12 carbon atoms.
