Abstract
Candles formed from triacylglycerol-based wax are provided. The wax generally has a melting point of about 130 to 145° F. (circa 54 to 63° C.). The wax includes a triacylglycerol component and a polyol partial ester component. Examples of suitable polyol partial esters include fatty acid monoesters of glycerol and/or sorbitan. The triacylglycerol-based wax typically has an Iodine Value of about 20 to 40. The wax commonly includes at least about 70 wt. % of the triacylglycerol component and about 3 to 30 wt. % of the polyol partial ester component. The triacylglycerol component generally has a fatty acid composition which includes about 50 to 70 wt. % saturated fatty acids and about 30 to 45 wt. % 18:1 fatty acids. Methods of producing the candles from the vegetable oil-based wax are also provided.
Claims34
A triacylglycerol-based candle wax comprising a triacylglycerol component and a polyol fatty acid partial ester component;

12 The wax of claim 1 wherein the polyol fatty acid partial ester component includes one or more esters selected from the group consisting of sorbitan triester of fatty acids having 16 to 18 carbon atoms.
A triacylglycerol-based candle wax comprising a triacylglycerol component and a polyol fatty acid partial ester component;
- wherein the wax has a melting point of about 54° C. to 63° C.;
