There are many types and classifications of Phthalates. As you may know, there are harmful Phthalates that are to be avoided and there are harmless Phthalates that are used in many products that we commonly use everyday. Unless it is listed in the description as Phthalate Free, then our fragrances have trace elements of the same harmless Phthalates that are used in these everyday products and makes our fragrances skin-safe for Bath and Body product usage. Phthalates used in fragrance oils, known as DEP (Diethyl Phthalate), are solvents used to extend the aromatic strength of the fragrance oil. DEP has been found to be non-toxic in skin products and candles if used at safe levels.
