Burning candles have long symbolized harmony, peace, and devotion, casting their gentle glow in homes and temples across centuries. However, there’s an important chemical aspect to consider when using candles in indoor environments.
During candle combustion, volatile organic compounds (VOCs) are released into the air, potentially posing hazards to consumers. Incomplete wax combustion can lead to the emission of carcinogenic compounds such as formaldehyde, benzene, and polycyclic aromatic hydrocarbons (PAHs). Additionally, carbon monoxide, soot, nitrogen oxides, and other byproducts are often present in candle smoke.
At LCS Laboratory Inc., we specialize in analyzing consumer goods and products for safety, including household candles. Our laboratory provides comprehensive analysis of gases, vapors, and particulates emitted during candle burning. Whether you’re innovating new candle designs or refining wax formulations, we conduct burning rate studies to precisely determine burn duration and efficiency.
During testing, we meticulously collect and analyze fumes and smoke from burning candles, offering valuable insights into their impact on indoor air quality. The test results are compiled into a comprehensive report, detailing data for approximately 60 different chemicals. Concentrations are presented in various units, such as micrograms per gram of burnt candle, parts per million in smoke, and micrograms per cubic meter of smoke, facilitating evaluation of candle safety and design optimization.
