Abstract:
A stabilized composition includes candle wax; an ultraviolet light absorber; and a hindered amine light stabilizer of formula (I). The compositions stabilize the candle with respect to yellowing, color fading in the case of dyed or pigmented candles, and other degradation of the waxes. The materials and compositions may be used in a wide variety of a candle waxes including, but not limited to, paraffin, beeswax, natural oils, polyamide plus fatty acids and esters thereof, fatty acids such as stearin, opacifiers, glycerides plus oxidized wax, alcohols, and ethylene oligomers.
