Our wax is a proprietary soy-blend wax that was formulated for maximum performance with our in-house manufactured fragrances. As with most fragranced candles, our fragrance contains both natural and synthetic ingredients. However, we adhere to strict IFRA standards, a 3rd party that sets safety standards for all-natural and synthetic aroma compounds. Likewise, we also follow the National Candle Association (NCA) for general wax and candle safety standards. According to the NCA, validated scientific studies have shown that all major candle waxes produce virtually identical combustion byproducts. To date, no peer-reviewed scientific study has ever proven that candle wax emissions are harmful to human health.
