Burn time is approximately 75-80 hours depending on air currents in the home or office. This soy candle is made from soybeans and completely biodegradable. They are renewable, sustainable, environmentally friendly, and biodegradable, water-soluble. Since the melting point for soy wax is relatively lower than petroleum or beeswax, they are longer lasting and have a cooler burn. Always burn candles in areas free from drafts. Never leave your candle unattended.
