Abstract
Wax compositions that have a high triacylglycerol content are provided. The wax compositions can be used to produce candle and are particularly useful in the production of container candles. The wax compositions commonly have a melting point of about 50° C. to 57° C. and include a triacylglycerol component which has a fatty acid composition including about 14 to 25 wt. % 16:0 fatty acid; about 20 to 30 wt. % 18:0 fatty acid; and about 45 to 60 wt. % 18:1 fatty acid. Methods of producing candles from a triacylglycerol-based wax and kits, which include the triacylglycerol-based wax, are also provided.
Claims22
A wax comprising a triacylglycerol component;
- wherein the wax has a melting point of about 50° C. to 57° C.;
- and the triacylglycerol component has a fatty acid composition which includes about 14 to 25 wt. % 16:0 fatty acid;
- about 20 to 30 wt. % 18:0 fatty acid;
- and about 50 to 60 wt. % 18:1 fatty acid.
A method for making a candle, comprising:
- (a) heating a wax, which has a melting point and a congeal point, to a temperature above the melting point of the wax thereby forming a hot liquefied wax;
- wherein the wax comprises at least about 50 wt. % of a triacylglycerol component;
- and the melting point is greater than the congeal point;
- (b) cooling the hot liquefied wax to a pour temperature thereby forming a cooled liquefied wax, wherein the pour temperature is below the melting point and above the congeal point;
- (c) pouring the cooled liquefied wax into a container;
- and
- (d) cooling the cooled liquefied wax in the container to a temperature below the congeal point of the wax thereby forming a candle;
- wherein the wax has a melting point of about 50° C. to about 57° C.;
- and the triacylglycerol component has a fatty acid composition which includes about 14 to 25 wt. % 16:0 fatty acid;
- about 20 to 30 wt. % 18:0 fatty acid;
- and about 45 to 60 wt. % 18:1 fatty acid.
A kit for making a candle comprising a wax which includes a triacylglycerol component;
- wherein the wax has a melting point of about 50° C. to 57° C.;
- and the triacylglycerol component has a fatty acid composition which includes about 14 to 25 wt. % 16:0 fatty acid;
- about 20 to 30 wt. % 18:0 fatty acid;
- and about 50 to 60 wt. % 18:1 fatty acid.
A container candle comprising a wax within a container and a wick embedded within the wax;
- wherein the wax has a melting point of about 51° C. to 55° C. and comprises at least about 75 wt. % of a triacylglycerol component;
- and the triacylglycerol component has a fatty acid composition which includes about 15 to 20 wt. % palmitic acid;
- about 20 to 30 wt. % stearic acid;
- and about 50 to 57 wt. % 18:1 fatty acid.
A candle comprising a wick and a wax;
- wherein the wax has a melting point of about 50° C. to 57° C. and comprises a triacylglycerol component;
- and the triacylglycerol component has a fatty acid composition which includes about 14 to 25 wt. % 16:0 fatty acid;
- about 20 to 30 wt. % 18:0 fatty acid;
- and about 50 to 60 wt. % 18:1 fatty acid.
