Fragrance oils are commonly used in making scented candles. They are a combination of natural essential oils and synthetic aroma chemicals, and they are never diluted, so each has a strong concentrated aroma
. Fragrance oils are different from essential oils, as essential oils are distilled from the oil of the plant from which they were extracted
. When using fragrance oils for candles, it's important to consider the quality and safety of the oils. The International Fragrance Association (IFRA), Research Institute for Fragrance Materials (RIFM), and the U.S. Food and Drug Administration (FDA) regulate standards for safety, purity, and the maximum amount of fragrance oil that's safe to use in products like soaps and cosmetics
. It's recommended to use fragrance oils that are phthalate-free and infused with essential oils for a cleaner and safer candle-burning experience
. Additionally, when making DIY scented candles, it's essential to choose fragrance oils that are tested for performance in soy wax and adhere well with the wax without impairing the burn quality of the candles
