Abstract
Abstract A wickless candle can be formed from a composition comprising 45 to 97.9 weight percent wax, 1 to 30 weight percent stearic acid and 1.1 to 25 weight percent ultrahigh molecular weight polyethylene. The wickless candle is easily ignitable, burns with little or no dripping and leaves little residue upon complete combustion. The wax can be a paraffin wax or a combination of paraffin wax and one or more of the following waxes: candellilla, carnauba, montan, spermaceti and beeswax. The ultrahigh molecular weight polyethylene refers to a polyethylene with a weight average molecular weight in the range of 500,000 to 6,000,000. The components of the composition are uniformly distributed therein.
