When lighting a candle, chemicals are released through a process called combustion. Combustion occurs when heat is applied to the candle's wick, causing the wax to melt and vaporize. As the wax vaporizes, it mixes with oxygen from the air and undergoes a chemical reaction, producing heat, light, water vapor, carbon dioxide, and other byproducts.
The main chemical released during the burning of a candle is carbon dioxide (CO2). This gas is a result of the carbon atoms in the wax combining with oxygen atoms from the air. Carbon dioxide is a colorless and odorless gas that is naturally present in the atmosphere.
In addition to carbon dioxide, burning candles can also release small amounts of other chemicals depending on the composition of the candle wax, fragrance additives, and dyes used. These chemicals may include volatile organic compounds (VOCs) such as formaldehyde, benzene, and toluene. The release of these compounds, although typically in low concentrations, can contribute to indoor air pollution and may cause respiratory irritation in some individuals, particularly those with sensitivities or allergies.
