One of the most talked about attributes of vegetable candles is their ability to burn clean. For those who rarely burn scented candles in their homes, a cleaner burn may not mean that much, but to frequent candle users, those who have been bothered by the black left around the jar tops and the gray, sooty residue soot left behind on walls, drapes and furnishings, a candle that produces considerably less or no soot is an astounding breakthrough.
So why do paraffin candles produce soot while soy candles don’t?
Soot is the solid particle that results from incomplete combustion of carbon containing fuels, primarily petroleum based fuels. This is called petro-carbon soot which is not found in soy wax. Soy wax is completely petro-carbon soot free. Soy candles produce zero petro-soot than traditional candles made from paraffin. Lower soot levels help maintain pure air quality and reduce home maintenance problems associated with soot deposits.
Soy wax has given consumers the ability to burn clean burning candles from sustainable sources. Farmers have a rapidly growing new market. Soy wax is the first wax innovation in the candle industry in over a 100 years and is rapidly becoming the candle industry standard for the twenty first century.
What would you rather have burning in your house?
There are several carcinogen compounds (cancer-causing agents) found in paraffin candles. Virtually all of them have been considered “toxic air agents” by various environmental agencies and the state of California, in particular.
Since soot particles are very small, they can potentially penetrate the deepest area of the lung. Researchers caution that the very young, the elderly and those with respiratory diseases like asthma should avoid exposure to candle soot.
Again soy wax burns petro-carbon soot free. But there are other factors that contribute to black soot deposits in candles.
Keep in mind the only completely soot free candle flame is a natural gas flame. This flame is completely blue in nature and has what is called a complete combustion.
Can we get a candle flame to combust completely? Well, almost. Candle Flames, wood burning fire places, all have incomplete combustion which produce soot, but the good news is it is not the toxic black petro carbon soot that you find in petroleum based candles.
There are some things you can do to radically limit the amount of soot produced from the candle flame itself. Learn more by reading our article about soot-free candles.
