Abstract

Wax compositions are provided with improved properties for candles and candle jars. The candle wax composition includes a major amount of a foots oil and minor amount of a 600N slack wax. In one form, the foots oil is a 150N foots oil that is included in the composition at from 70 to 80 weight % of the composition and the 600N slack wax is included in the composition at from 20 to 30 wt % of the composition. The candle wax composition provides substantially no oil bleed and a smooth surface appearance with improved burning properties in terms of soot production, wax consumption, melt pool depth and flame height.

First claim

The invention claimed is:

1. A candle wax composition comprising a major amount of a 150N foots oil and a minor amount of a 600N slack wax.

2. The composition of claim 1 , wherein the major amount of the 150N foots oil ranges from 70 to 80 wt % of the composition.

3. The composition of claim 2 , wherein the minor amount of the 600N slack wax ranges from 20 to 30 wt % of the composition.

4. The composition of claim 3 further comprising one or more coloring agents, one or more fragrances, or combinations thereof.

5. The composition of claim 4 , wherein the one or more coloring agents range from 0.5 to 5 wt % of the composition.

6. The composition of claim 4 , wherein the one or more fragrances range from 0.5 to 5 wt % of the composition.

7. The composition of claim 3 , wherein the composition has substantially no oil bleed on the surface.

8. The composition of claim 3 , wherein the composition has a smooth surface appearance.

9. The composition of claim 3 , wherein the composition has a dropping point of from 50 to 58 deg. C.

10. The composition of claim 3 , wherein the composition upon burning yields a soot production ranging from 400 to 470 μg Soot/g wax.

11. The composition of claim 3 , wherein the composition upon burning yields a melt pool depth ranging from 6 to 14 mm.

12. The composition of claim 3 , wherein the composition upon burning yields a flame height to melt pool ratio in a range of 0.8 to 1.2.

13. The composition of claim 3 , wherein the composition upon burning yields a wax consumption per hour of 2.0 to 2.7 g/hour.

14. A candle jar comprising the candle wax composition of claim 3 .

15. The candle jar of claim 14 , wherein the composition adheres to sides of the candle jar with substantially no frosting and substantially no cracking of the wax surface.
