Wax and wax-based products
View Patent ↗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.
1. A candle comprising a wick and a lipid-based wax:
wherein the lipid-based wax comprises at least about 51 wt. % of a completely esterified polyoi fatty acid ester component;
wherein the lipid-based wax has a melting point of about 50° C. to about 60° C.; an Iodine Value of about 40 to 75; and a solid fat content at 10° C. (SFC-10): solid fat content at 40° C. (SFC-40) ratio of at least about 2.0.
2. The candle of claim 1 wherein the lipid-based wax has a slump temperature of at least about 118° F.
3. The candle of claim 1 wherein the lipid-based wax has an SFC-40 of at least about 20.
4. The candle of claim 1 wherein the lipid-based wax includes no more than about 1.0 wt. % free fatty acid.
5. The candle of claim 1 wherein the completely esterified polyol fatty acid ester component includes a fully interesterified triacylglycerol component.
6. The candle of claim 1 wherein the lipid-based wax further comprises a polyol fatty acid partial ester.
7. The candle of claim 1 wherein the lipid-based wax further comprises a crystal modifier.
8. The candle of claim 1 wherein the lipid-based wax has an SFC-40 of at least about 40.
9. The candle 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.
10. The candle of claim 1 wherein the lipid-based wax comprises a tnacylglycerol component having a fatty acid composition which includes no more than about 15 wt. % palmitic acid.
11. The candle of claim 1 wherein the lipid-based wax includes a fatty acid monoglyceride ester, a fatty acid diglyceride ester or a mixture thereof.
12. The lipid-based wax of claim 1 wherein the fully interesterified polyol fatty acid ester component includes a fully interesterifled triacylglycerol component and the lipid based wax comprises at least about 51 wt. % of the fully interesterifled triacylglycerol component.
