Abstract: The organophilic clay comprises a smectite-type clay ion exchanged with quaternary ammonium ions, where at least 75 mol-% of said quaternary ammonium ions are bis-(2-hydroxypropyl)-dimethylammonium fatty acid esters and at least 90% of the fatty acid moieties of the bis-(2-hydroxypropyl)-dimethylammonium fatty acid esters have a structure RC(O) with group R being a linear alkyl or alkenyl group containing from 9 to 21 carbon atoms. The organophilic clay is useful for thickening oil based compositions, in particular drilling fluids for drilling oil or gas wells, comprising an oil phase.

Abstract: The present invention is directed to compositions that are characterized by the presence of ester quats with specific characteristics that promote dispersibility at low temperature. Among the important characteristics of the ester quats are an iodine value of 65-85 and distribution of: 33-38% monoesters, 50-55% diesters and 7-12% triesters.
