Abstract

Natural oil based fatty acid wax compositions and their methods of making are provided. The methods comprise providing a natural oil, and hydrogenating and metathesizing the natural oil, and then converting the hydrogenated metathesized natural oil to obtain a fatty acid wax comprising free fatty acids and/or salts of fatty acids, glycerol and/or alcohol, and paraffin, wherein the fatty acid wax has at least 50 wt % of carbon chain compositions with at least 18 carbon atoms. The compositions may comprise 85-100 wt % long-chain fatty acids, 0-15 wt % esters, wherein the fatty acid comprises between 15-60 wt % long chain di-acids and 40-85 wt % long chain mono-acids. The compositions may comprise about 50-100 wt % long-chain fatty acids and about 0-50 wt % esters, wherein the fatty acid may comprise between about 15-80 wt % long chain di-acids and about 20-85 wt % long chain monoacids.
