Scent Notes: cactus flower, jade, and patchouli. Burn Times: 4 oz jars up to 30 hours Components: these candles contain all natural soy wax, cotton wicks, and phthalate-free fragrances. Soy Wax The soy wax used 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 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 fragrance oils are phthalate-free and do not require a prop 65 warning.
