Abstract
A thickened composition is disclosed which comprises (A) at least one triglyceride estolide of the formula ##STR1## wherein R.sup.1 is an aliphatic group or an aliphatic group containing an ester moiety R.sup.2 COO-- with the proviso that at least one R.sup.1 is an aliphatic group containing the ester moiety, and contains from about 5 to about 23 carbon atoms, and R.sup.2 is a hydrocarbyl group containing from 1 to 100 carbon atoms and (B) at least one oil comprising (1) a synthetic ester base oil (2) a mineral oil, or (3) a polyalphaolefin.
