We use Fragrance Oils that are specifically formulated with clean and safe compounds. Fragrance Oils are synthetically compounded, and should not be confused with the 100% natural Essential Oils. Please note that all our Fragrance Oils are paraben-free, phthalate-free, lyral-free, and lilial-free, which makes them safer for you and the environment, but may offer a slightly milder throw in candles and wax melts from other super synthetic competitors.
