Abstract

The present lipid-based wax compositions commonly include a polyol fatty acid ester component (made up of partial and/or completely esterified polyols). Generally, at least a portion of the polyol fatty acid ester has been subjected to a transesterification reaction. Lipid-based wax compositions having a melting point of about 48° C. to about 75° C. can be particularly advantageous for use in forming candles. The wax may contain other components such as mineral wax, plant wax, insect wax, and/or other components. The polyol fatty acid ester component can include triacylglycerols such as those derived from plant oils (soybean oil, palm oil, etc.). The polyol ester component may be characterized based on one or more of its physical characteristics, such as SFI-40, SFI-10, typical crystal structure, IV, melting curve, and/or other properties.

Claims (15)

1. A lipid-based wax comprising at least about 51 wt. % of a fully interesterified polyol fatty acid ester component;

wherein the lipid-based wax has a melting point of about 135° F. to 160° F. (57° C. to 71° C.); and an SFI-40 of at least about 40.

2. The lipid-based wax of claim 1 , wherein the lipid-based wax has a slump temperature of at least about 120° F.

3. The lipid-based wax of claim 2 , wherein the fully interesterified polyol fatty acid ester component includes a fully interesterified triacylglycerol component.

4. The lipid-based wax of claim 1 , wherein the lipid-based wax has a melting point of at least about 60° C.

5. The lipid-based wax of claim 1 , wherein the lipid-based wax further comprises a polyol fatty acid partial ester.

6. The lipid-based wax of claim 1 , wherein the lipid-based wax includes a fatty acid monoglyceride ester, a fatty acid diglyceride ester or a mixture thereof.

7. The lipid-based wax of claim 1 , wherein the lipid-based wax further comprises a second component selected from the group consisting of petroleum waxes, insect waxes, free fatty acids and mixtures thereof.

8. A lipid-based wax wherein the lipid-based wax has a melting point of about 48° C. to about 75° C. and includes at least about 51 wt. % of a triacylglycerol component having a fatty acid composition which includes X wt. % stearic acid; and the triacylglycerol component has a SSS-TAG content which is given by (X 3 /10 4 )+/−3 wt. %.

9. A lipid-based wax comprising at least about 51 wt. % of a fully interesterified polyol fatty acid ester component;

wherein the lipid-based wax has a melting point of about 48° C. to about 75° C.; and an SFI-40 of at least about 40.

10. The lipid-based was of claim 9 wherein the triacylglycerol component has a fatty acid composition which includes X wt. % stearic acid; and the triacylglycerol component has a SSS-TAG content which is given by (X 3 /10 4 )+/−3 wt. %.

11. The lipid-based wax of claim 1 , wherein the lipid-based wax has a melting point of at least about 60° C.

12. A lipid-based wax comprising at least about 51 wt. % of a fully interesterified polyol fatty acid ester component;

wherein the lipid-based wax has a melting point of at least about 60° C.; and an SFI-40 of at least about 40.
