Abstract
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.
