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° C., (b) a fire point of at least 230° C., (c) a pour point of −25° 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.
