I hear a lot of talk about phthalates and phthalate-free fragrance oils. What does this mean?
"Phthalates" is a broad term that refers to a wide variety of compounds of differing chemical structure. Safety concerns have been raised about Dibutyl Phthalate (DBP) and Diethyl Hexyl Phthalate (DEHP). DEP as used in fragrances is safe for human health and the environment. The International Fragrance Association (IFRA) makes clear that consumers can use fragranced products containing DEP with confidence. In fact, the safety profile for DEP based on "Human Health Criteria" shows DEP to be safer for use on humans than any natural essential oil. DEP is particularly useful in candle fragrances as it solubilizes fragrance into the wax and prevents "crystalization" in certain fragrance oils.
