Description

Technical Field

Background Art

[0002] At present, the main raw material for making candles is paraffin wax. Paraffin wax has good performance, uniform appearance, no spots, no oil at high temperatures, and no cracking at low temperatures. Therefore, paraffin wax is added to the candle formula to adjust the formula. However, paraffin wax is a non-renewable resource. With the continuous rise in paraffin prices and the problem of export anti-dumping duties, the cost of paraffin formula candles has continued to increase, which directly affects the development of the candle market. More importantly, paraffin candles will produce black smoke during combustion, which contains harmful substances such as polycyclic aromatic hydrocarbons, metal ions, and sulfur-containing compounds, which seriously damage human health. With the increasing requirements of consumers for living environment and environmental awareness, consumers prefer candles made from plant wax formulas.

[0003] At present, the raw materials of plant wax include palm wax, soybean wax and shea wax. Plant wax is composed of triglycerides and fatty acids, and contains a large number of unsaturated bonds. When burning, these bonds are easily broken by heat into smaller molecular hydrocarbons and diglycerides and other organic substances. The rapid decomposition of these small molecular organic substances does not have time to react with oxygen during combustion, forming carbon deposits. In addition to containing a lipid mixture, it also contains some other ingredients, which will cause carbon deposits during combustion, and the candle wick will form a mushroom head, affecting the burning of the candle. Solving the problem of carbon deposits during the combustion of plant wax has become a new direction for the research of plant wax. Summary of the invention
