Burn Times: 8 oz jars up to 55 hours  |  16 oz jars up to 80 hours | 4 oz jars up to 30 hours | 1 oz tins up to 4 hours Components: Our candles contain all natural soy wax, cotton wicks, and phthalate-free fragrances. Soy Wax The soy wax we use is produced from soybeans grown in the US. Some of the benefits of soy wax are that it burns cleaner and slower than other waxes. Soy is a renewable and sustainable resource that is carbon neutral and eco-friendly.  And as a bonus, soy wax is naturally vegan.  Cotton Wick The wicks we use are made up of braided cotton with thin paper threads to provide structure without the need of a core. They are zinc and lead free. Fragrance Oils All of our fragrance oils are phthalate-free and do not require a prop 65 warning. We choose to use fragrance oils over essential oils due to better scent throw, cost, and overall performance.
