Wax compositions and surface tension
Disclosed herein is a method of using surface tension to control the manufacture of candles until a surface tension ranging from 20 to 30 dynes/cm is achieved.
1. A method of making a candle wax composition, the method comprising:
purifying a modified natural oil to provide the candle wax composition, the purifying comprising
bleaching the modified natural oil,
monitoring the surface tension of the candle wax composition,
if the surface tension is outside of the range of from 20-30 dynes/cm, then further performing the purifying, and
if the surface tension is in the range of from 20-30 dynes/cm, then providing the candle wax composition:
wherein a candle comprising the candle wax composition has a different rate of consumption than an otherwise identical candle comprising the modified natural oil composition in place of the candle wax composition.
2. The method of claim 1 , wherein the purification is performed until the surface tension of the candle wax composition ranges from 29.1-30 dynes/cm.
3. The method of claim 1 , wherein the purification is performed until the surface tension of the candle wax composition ranges from 29.2-30 dynes/cm.
4. The method of claim 1 , wherein the purification is performed until the surface tension of the candle wax composition ranges from 29.3-29.9 dynes/cm.
5. The method of claim 1 , further comprising purifying the modified natural oil until the candle wax composition has a surface tension ranging from 20-30 dynes/cm and a nickel content less than 0.5 ppm.
6. The method of claim 1 , further comprising purifying the modified natural oil until the candle wax composition has a surface tension ranging from 20-30 dynes/cm and a nickel content less than 0.2 ppm.
7. The method of claim 1 , further comprising purifying the modified natural oil until the candle wax composition has a surface tension ranging from 20-30 dynes/cm and a nickel content less than 0.1 ppm.
8. The method of claim 1 , further comprising purifying the modified natural oil until the candle wax composition has a surface tension ranging from 20-30 dynes/cm and a dissipation factor ranging from 0.0001-0.0600.
9. The method of claim 1 , further comprising purifying the modified natural oil until the candle wax composition has a surface tension ranging from 20-30 dynes/cm, a dissipation factor ranging from 0.0001-0.0600, and a nickel content less than 0.5 ppm.
10. The method of claim 1 , wherein the rate of consumption of a candle comprising the candle wax composition ranges from 3-4 grams per hour.
11. The method of claim 1 , wherein the rate of consumption of a candle comprising the candle wax composition ranges from 3.25-3.75 grams per hour.
12. The method of claim 1 , wherein a candle comprising the candle wax composition has a flame height ranging from 0.25-1.5 inches.
13. The method of claim 1 , wherein the natural oil is 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, castor oil, or mixtures thereof.
14. The method of claim 1 , wherein purifying the modified natural oil comprises purifying a blend of the modified natural oil and paraffin, wherein paraffin is present in a majority amount.
15. A method of forming a candle wax composition, the method comprising:
finishing a candle wax composition comprising adjusting surface tension and dissipation factor of the candle wax composition until the surface tension ranges from 20-30 dynes/cm and until the dissipation factor ranges from 0.0001-0.0600, the adjusting of surface tension comprising
adding a surface tension modifier to the candle wax composition,
monitoring surface tension of the candle wax composition, and
if the surface tension is outside of the range of from 20-30 dynes/cm, then further performing the adjusting of surface tension;
wherein a candle comprising the pre-finished candle wax composition has a different rate of consumption than an otherwise identical candle comprising the finished candle wax composition in place of the pre-finished candle wax composition.
16. The method of claim 15 , wherein the finishing comprises adjusting the surface tension and a nickel content of the candle wax composition until the surface tension ranges from 20-30 dynes/cm and the nickel content is less than 0.5 ppm.
17. The method of claim 15 , further comprising wherein the finishing comprises adjusting the surface tension, the dissipation factor, and a nickel content of candle wax composition until the surface tension ranges from 20-30 dynes/cm, the dissipation factor ranges from 0.0001-0.0600, and the nickel content is less than 0.5 ppm.
18. The method of claim 15 , wherein the surface tension modifier is a siloxane additive.
