Abstract

A wax comprises a metathesis product and/or a product that resembles, at least in part, a product which may be formed from a metathesis reaction. The wax may be used to form articles, for example, candles (container candles, votive candles, and/or a pillar candles), crayons, fire logs, or tarts. The wax commonly includes other components in addition to the metathesis product.

Claims

1. A wax composition comprising:

(a) a metathesis product formed from a base stock comprising a polyol fatty acid ester having a fatty acid composition that includes at least one unsaturated fatty acid; and

(b) at least one of;

polyol fatty acid ester stock, paraffin wax, fatty acid, carnauba wax, and beeswax;

wherein the wax composition has a melting point of about 20°

C. to about 70°

C.

2. The wax of claim 1, wherein the wax composition has a melting point of about 45°

C. to about 70°

C.

5. The wax of claim 1, wherein the metathesis product is hydrogenated.

6. The wax of claim 1, wherein the metathesis product comprises hydrogenated triacylglyceride metathesis product.

7. The wax of claim 6, wherein the hydrogenated metathesis product comprises hydrogenated triacylglyceride metathesis dimer.

8. The wax of claim 6, wherein the hydrogenated metathesis product comprises hydrogenated triacylglyceride metathesis trimer.

12. The wax of claim 1, wherein the base stock comprises a vegetable oil having an Iodine Value of at least about 45.

13. The wax of claim 1, wherein the base stock comprises soybean oil, canola oil, palm oil, sunflower oil, cottonseed oil, rapeseed oil, tallow, linseed oil, corn oil, palm kernel oil, coconut oil, lard, chicken fat, or tall oil.

14. The wax of claim 1, wherein the wax comprises about 10 to 40 wt. % of the metathesis product.

17. The wax of claim 1, wherein the wax comprises stearic acid, palmitic acid or a mixture thereof.

18. The wax of claim 1, wherein the wax comprises glycerol monostearate, glycerol monopalmitate or a mixture thereof.
