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.
Claims20
A method of making a natural oil-based candle wax composition, the method comprising:
- removing nickel from one or more nickel-hydrogenated plant oils to provide a hydrogenated natural oil having a nickel content of less than 0.5 ppm;
- wherein the candle wax composition comprises the hydrogenated natural oil.
A method of forming a hydrogenated natural oil for use in candles, the method comprising:
- processing a hydrogenated natural oil to reduce nickel content thereof to 0.05 ppm to 0.5 ppm, wherein the natural oil comprises one or more plant oils, wherein the hydrogenated natural oil has a fatty acid composition corresponding to that of the one or more plant oils.
A method of forming a hydrogenated natural oil for use in candles, the method comprising:
- removing nickel from a nickel-hydrogenated natural oil, the natural oil comprising one or more plant oils, the removing comprising filtration, treatment with bleaching clay, or a combination thereof, to form the hydrogenated natural oil, wherein the hydrogenated natural oil has a nickel content of less than 0.5 ppm, wherein fatty acyl chain lengths of the hydrogenated natural oil are the same as fatty acyl chain lengths of the one or more plant oils.
