All of Candle Cocoon's oils always have been and always will be phthalate free. They are as concentrated as possible with no extra solvents. Each one is unique and takes 6 months to 4 years to have developed. Each our our scents is tested and tested and tested. We test for scent throw and wick size. We test BEFORE the scents get to you!
***All fragrance and essential oils are heat and light sensitive. We ship in opaque plastic bottles to save on gas (glass is heavy). But unused oils should be transferred to amber bottles and stored in a cool dark and dry place if not used within a month or two.
