Triacyglycerol based candle wax
View Patent ↗A triacylglycerol-based wax includes a triacylglycerol component and a polyol fatty acid partial ester component. The triacylglycerol-based wax may have a melting point of about 54° C. to 63° C., may have an Iodine Value of about 20 to 40, and may have a fatty acid profile including about 50 to 70 wt. % saturated fatty acids. The wax may be suitable for use as a candle.
1. A triacylglycerol-based wax comprising:
at least about 70 wt. % of a triacylglycerol component; and
about 5 to 25 wt. % of a polyol monoester component;
wherein the polyol monoester component comprises glycerol fatty acid monoester and/or sorbitan fatty acid monoester;
wherein the wax has an Iodine Value of about 20 to 40; and
wherein the wax has no more than about about 1.0 wt. % free fatty acid.
2. The wax of claim 1 wherein the triacylglycerol component has a fatty acid composition of about 50 to 70 wt. % saturated fatty acid(s) and about 30 to 45 wt. % 18:1 fatty acid.
3. The wax of claim 1 wherein the triacylglycerol component has an Iodine value of about 30-45.
4. The wax of claim 1 comprising at least about 80 wt. % of a triacylglycerol component and about 3 to 15 wt. % of a glycerol fatty acid monoester component.
5. The wax of claim 1 , where the a triacylglycerol component comprises a blend of fully hydrogenated palm oil and fully hydrogenated soybean oil.
6. The wax of claim 1 wherein the triacylglycerol component has a fatty acid profile including about 8 to 12 wt. % 16:0 fatty acid, about 40 to 45 wt. % 18:1 fatty acids and about 40 to 45 wt. % 18:0 fatty acid.
7. The wax of claim 1 wherein the triacylglycerol component has a fatty acid profile including about 20 to 25 wt. % 16:0 fatty acid, about 40 to 45 wt. % 18:1 fatty acids and about 30 to 35 wt. % 18:0 fatty acid.
8. A triacylglycerol-based wax comprising a triacylglycerol component and a polyol fatty acid partial ester component; wherein the triacylglycerol-based wax has a fatty acid profile including about 50 to 70 wt. % saturated fatty acids and about 30 to 45 wt. % 18:1 fatty acids; wherein the saturated fatty acids comprise about 8 to 25 wt. % based on the total fatty acid profile of the triacylglycerol component of 16:0 fatty acid, and about 30 to 45 wt. % based on the total fatty acid profile of the triacylglycerol component of 18:0 fatty acid.
9. The wax of claim 8 wherein the wax comprises no more than about 1.0 wt. % free fatty acid.
10. The wax of claim 8 comprising at least about 80 wt. % of the triacylglycerol component and about 3 to 15 wt. % of a glycerol fatty acid monoester component.
11. The wax of claim 8 , where the a triacylglycerol component comprises a blend of fully hydrogenated palm oil and fully hydrogenated soybean oil.
12. A triacylglycerol-based wax comprising at least about 80 wt. % of a triacylglycerol component and about 3 to 15 wt. % of a glycerol fatty acid monoester component; wherein the triacylglycerol-based wax an Iodine Value of about 20 to 40 and contains no more than about 1.0 wt. % free fatty acid; and the triacylglycerol component has a fatty acid profile including about 50 to 65 wt. % saturated fatty acids and about 30 to 45 wt. % 18:1 fatty acids.
13. The wax of claim 12 wherein a glycerol fatty acid monoester has an Iodine Value of no more than about 10 and includes glycerol monostearate, glycerol monopalmitate or a mixture thereof.
14. The wax of claim 12 comprising about 85 to 95 wt. % of the triacylglycerol component and about 5 to 15 wt. % of the glycerol fatty acid monoester component; wherein the wax has an Iodine Value of about 25 to 30; and the triacylglycerol component has a fatty acid profile including about 30 to 35 wt. % 18:1 fatty acids and about 60 to 65 wt. % saturated fatty acids.
15. The wax of claim 12 further comprising about 0.5 to 20. Wt. % of a polymerized alpha olefin migration inhibitor.
