Patent number: 10179888Abstract: Lipid-based wax compositions and their methods of making are provided for compositions substantially free of fat bloom. The compositions comprise 0.1-10 percent by weight triacylglycerides, 30-95 percent by weight monoacylglycerides and diacylglycerides combined, and 0.1-65 percent by weight fatty acids. The methods comprise blending the monoacylglycerides, diacylglycerides, triacylglycerides, and fatty acids by heating the lipid-based wax composition at a sufficiently high temperature to destroy substantially all crystal structure within the lipid-based wax composition. The methods further comprise pouring the lipid-based wax composition into a mold or a container having a surface and a core, wherein the pouring is conducted at a temperature at least 15° C. greater than the congeal point of the lipid-based wax composition. The methods further comprise cooling the lipid-based wax composition under conditions sufficient to cool the core to at least 5° C.Type: GrantFiled: September 29, 2016Date of Patent: January 15, 2019Assignee: CARGILL, INCORPORATEDInventors: Timothy A.

Patent number: 9290719Abstract: 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.Type: GrantFiled: December 27, 2012Date of Patent: March 22, 2016Assignee: Elevance Renewable Sciences, Inc.Inventors: Monika Mujkic, Michael Tupy, Stephen E.

Patent number: 4239546Abstract: This invention relates to the use of hydrocarbon polymers to improve the hardness of waxes. Blends of hydrocarbon polymers in soft waxes are unexpectedly harder than each component thereof. In addition the blending of hydrocarbon polymers into waxes has a lesser effect on the undesirable properties of (1) increased viscosities and (2) increased cloud points, than occurs when polyethylene are blended into wax.Type: GrantFiled: July 21, 1978Date of Patent: December 16, 1980Assignee: Petrolite CorporationInventors: Stephen E.
