ABSTRACT:
A triacylglycerol based wax, which may be used to form container candles, is disclosed. The triacylglycerol-based wax includes a triacylglycerol component and a polyol fatty acid partial ester component. The triacylglycerol-based wax typically has a melting point of about 49° C. to 58° C. The triacylglycerol-based wax also generally has an Iodine Value of about 45 to 65. The triacylglycerol component tends to have a fatty acid composition including 5 to 13 wt. % 16:0 fatty acid. Further, the fatty acid composition generally comprises about 45 to 60 wt. % 18:1 fatty acid. The fatty acid composition also generally comprises about 30 to 45 wt. % 18:0 fatty acid. The wax preferably contains little or no paraffin and free fatty acid. The polyol partial ester component is preferably a glycerol monoester of palmitic and stearic fatty acids, and is commonly present as less than about 5 wt. % of the wax.
