Abstract
This invention relates to wax formulations comprised of specific poly(oxyalkylenated) colorants having fatty ester terminal groups. Preferably the wax formulation is a candle. Such polymeric ester capped colorants provide excellent coloring, decreased migratory properties, and improved balanced burning characteristics over traditional candle colorants and dyestuffs. This invention also concerns methods of making the aforementioned colored candle formulations as well as other colored wax articles, such as crayons.
