Abstract
A wax composition is disclosed, comprising a hydrogenated natural oil with (i) at least about 50 wt % of a triacylglycerol component having a fatty acid composition from about 14 to about 25 wt % C16:0 fatty acid, about 45 to about 60 wt % C18:1 fatty acid and about 20 to about 30 wt % C18:0 fatty acid, (ii) a nickel content of less than 1 ppm, and (iii) a melt point of about 49° C. to about 57° C. The hydrogenated natural oil is filtered and/or bleached to obtain a nickel content of less than 0.5 ppm. A candle is also disclosed, comprising a wick and the above described wax.

1-21. (canceled)
A method of making a candle, the method comprising:
- providing a mold having a wick disposed therein;
- providing a wax composition, which is in a molten state, and comprises a hydrogenated natural oil composition;
- pouring the wax composition into the mold;
- and
- cooling the wax composition after pouring it into the mold;
- wherein the hydrogenated natural oil composition has a nickel content of less than 0.5 ppm, and is formed by a process comprising:
- hydrogenating a natural oil in the presence of nickel to form a crude hydrogenated natural oil composition that comprises nickel;
- and
- treating the crude hydrogenated natural oil composition to reduce the nickel content to a concentration of less than 0.5 ppm and to form the hydrogenated natural oil composition.
