Abstract

Lipid-based wax compositions and their methods of making are provided for compositions substantially free of fat bloom. The compositions comprise 0.1-10 percent by weight triacylglycerides, 30-95 percent by weight monoacylglycerides and diacylglycerides combined, and 0.1-65 percent by weight fatty acids. The methods comprise blending the monoacylglycerides, diacylglycerides, triacylglycerides, and fatty acids by heating the lipid-based wax composition at a sufficiently high temperature to destroy substantially all crystal structure within the lipid-based wax composition. The methods further comprise pouring the lipid-based wax composition into a mold or a container having a surface and a core, wherein the pouring is conducted at a temperature at least 15° C. greater than the congeal point of the lipid-based wax composition. The methods further comprise cooling the lipid-based wax composition under conditions sufficient to cool the core to at least 5° C. below the congeal point of the lipid-based wax composition in 30-90 minutes.

First claim

What is claimed is:

1. A lipid-based wax composition comprising greater than or equal to 0.1 and less than 10 percent by weight triacylglycerides, greater than or equal to 50 and less than or equal to 95 percent by weight monoacylgycerides and diacylglycerides combined, and 0.1 to 65 percent by weight free fatty acids.

2. The lipid-based wax composition of claim 1 comprising: greater than or equal to 1 and less than 5 percent by weight triacylglycerides; greater than or equal to 50 and less than or equal to 80 percent by weight monoacylglycerides and diacylglycerides combined; and 5-50 percent by weight fatty acids.

3. The lipid-based wax composition of claim 1 comprising: greater than or equal to 2 and less than 5 percent by weight triacylglycerides; greater than or equal to 50 and less than or equal to 65 percent by weight monoacylglycerides and diacylglycerides combined; and 30-50 percent by weight fatty acids.

4. The lipid-based wax composition of claim 1 comprising: 25-45 percent by weight monoacylglycerides; and 10-30 percent by weight diacylglycerides.

5. The lipid-based wax composition of claim 1 comprising: greater than or equal to 2 and less than 5 percent by weight triacylglycerides; 30-40 percent by weight monoacylglycerides; 15-25 percent by weight diacylglycerides; and 35-45 percent by weight fatty acids.

6. The lipid-based wax composition of claim 1 , wherein the monoacylglycerides, diacylglycerides, triacylglycerides, and fatty acids are derived from natural oils selected from the group consisting of canola oil, rapeseed oil, coconut oil, corn oil, cottonseed oil, olive oil, palm oil, peanut oil, safflower oil, sesame oil, soybean oil, sunflower oil, linseed oil, palm kernel oil, tung oil, jatropha oil, mustard oil, camelina oil, pennycress oil, hemp oil, algal oil, castor oil, lard, tallow, poultry fat, yellow grease, fish oil, tall oils, and mixtures thereof.

7. The lipid-based wax composition of claim 1 , wherein the monoacylglycerides, diacylglycerides, triacylglycerides, and fatty acids are derived from palm oil or soybean oil.

8. The lipid-based wax composition of claim 1 , wherein the lipid-based wax composition has a melting point between 55° C. and 75° C.

9. The lipid-based wax composition of claim 1 , wherein the lipid-based wax composition further comprises at least one additive selected from the group consisting of wax-fusion enhancer additives, coloring agents, scenting agents, migration inhibitors, additional optimal wax ingredients, surfactants, co-surfactants, emulsifiers, metals, individually or in combinations thereof.

10. The lipid-based wax composition of claim 1 , wherein the monoacylglycerides and the diacylglycerides comprise a residual inorganic complex selected from the group consisting of phosphates, phosphites, nitrates, sulfates, chlorides, bromides, iodides, nitrides, and mixtures thereof, wherein the concentration of the residual inorganic complex is less than 15 ppm in the monoacylglycerides and the diacylglycerides combined.

11. The lipid-based wax composition of claim 1 , wherein the comprising monoacylglycerides and the diacylglycerides comprise an organic acid selected from the group consisting of citric acid, lactic acid, oxalic acid, carboxylic acid, and mixtures thereof, and further wherein the concentration of the organic acid is less than 500 ppm in the monoacylglycerides and the diacylglycerides combined.

12. The lipid-based wax composition of claim 1 , comprising greater than or equal to 50 and less than or equal to 60 percent by weight monoacylgycerides and diacylglycerides combined.

13. The lipid-based wax composition of claim 1 , wherein the triacylglycerides, monoacylgycerides and diacylglycerides, and free fatty acids make up 100 percent of the lipid based wax composition.

14. A lipid-based wax composition comprising greater than or equal to 0.1 and less than 10 percent by weight triacylglycerides, greater than 35 and less than or equal to 95 percent by weight monoacylgycerides and diacylglycerides combined, and 0.1 to 65 percent by weight free fatty acids, and wherein the triacylglycerides, monoacylgycerides and diacylglycerides, and free fatty acids make up 100 percent of the lipid based wax composition.
