When to throw away essential oils?
Many essential oils will last about 2–5 years if stored in closed, dark glass bottles kept out of direct light and heat. Some oils like Patchouli, Sandalwood, and Vetiver can last 6–8 years. Here are some timelines for popular essential oils: 1–2 years: Lemon, Lime, and Tangerine. All essential oils will expire eventually, but with good care and storage practices, you may even be able to make it last beyond the approved date. Keep them in a cool dry location inside a dark bottle away from heat and light, and seal the bottle when not in use.
How do you know if essential oils are 100% pure?
GC/MS testing is the most reliable test of an essential oil’s purity. The test can isolate every component within an essential oil, as well as the exact amounts of each component. Our Certified Pure Tested Grade (CPTG) protocol involves rigorous testing, including Gas Chromatography and Mass Spectrometry, to guarantee that each batch is free from contaminants and additives. This process is a cornerstone of our promise to offer 100% pure essential oils.
