    • There is provided a process for the preparation of a compound having the formula (I) wherein R 1 , R 2 and R 3 are independently selected from hydrogen and acyl groups, wherein at least one of R 1 , R 2 and R 3 is a branched chain long acyl group of the formula (II) wherein n is from 9 to 21 and m is 2n, and wherein p is from 0 to 4 wherein the other of R 1 , R 2 and R 3 are selected from short acyl groups of the formula (III) wherein q is from 0 to 4 the process comprising the steps of: (1 ) providing an unsaturated compound having the formula (I) wherein R 1 , R 2 and R 3 are independently selected from (a) hydrogen, (b) unsaturated long acyl group of the formula (IV) wherein x is from 0 to 3, and wherein n is from 9 to 21 and m is 2n-1-x, 2n-3-x or 2n-5-x;and (c) short acyl groups of the formula (III) wherein q is from 0 to 4 wherein at least one of R 1 , R 2 and R 3 is an unsaturated long acyl group; and (2) if at least one of R 1 , R 2 and R 3 is hydrogen, optionally acylating the compound; and (3a) (i) hydroxylating the unsaturated long acyl group, to provide a hydroxy long acyl group of the formula (V) wherein y is from 1 to 4, n is from 9 to 21 and m is 2n+1-y, 2n-1-y or 2n-3-y, and (ii) acylating the hydroxy long acyl group to provide a branched long acyl group of the formula (VI) wherein z is from 1 to 4, n is from 9 to 21 and m is 2n+1-z, 2n-1-z or 2n-3-z, and wherein p is from 0 to 4; or (3b) reacting the unsaturated long acyl group with a carboxylic acid of the formula (VII) to provide a branched long acyl group of the formula (VI) wherein z is from 1 to 4, n is from 9 to 21 and m is 2n+1-z, 2n-1-z or 2n-3-z, and wherein p is from 0 to 4.
