Most mass produced candles are made from paraffin wax, a derivative of petroleum, which contributes to greenhouse gas emissions. Soy wax is made from a renewable resource (soybeans) and offers an alternative that doesn't rely on fossil fuels. Additionally, the burning of paraffin wax releases small amounts of toxins like formaldehyde, acetone, benzene, and tuolene into the air. Burning soy wax produces substantially fewer VOCs than paraffin wax. Soy candles also emit less soot than paraffin for a cleaner burn. Please be aware that the burning of any candle, regardless of wax type, releases combustion byproducts into the air. Moderation and proper ventilation are key to maintaining good indoor air quality.
