Quality isn’t something we’re willing to take someone else’s word for. It’s something we want to understand firsthand. 🌿
That’s why members of our team recently visited The Perfumery, our primary essential oil supplier. CEO Ben, CMO Kate, Marketing Manager Victoria, and Quality Assurance Manager Joy toured the facility together.
We wanted to meet the people behind our ingredients, see their processes for ourselves, understand what matters to them, and ask the kinds of questions that help us make better decisions for Earthley families.
During the visit, we toured their facility and laboratory and learned how their team evaluates essential oils using six different testing methods:
🔬 GC-MS testing
👃 Organoleptic evaluation
⚖️ Specific gravity
💧 Refractive index
↩️ Optical rotation
🎨 Colorimeter testing
No single test tells the whole story. Together, these methods help verify that an oil is what it claims to be and that it meets established quality standards.
Strong products begin with strong relationships. Knowing the people who supply our ingredients, understanding how they work, and seeing how seriously they take quality gives our team greater insight and accountability at every step.
When it comes to essential oils, a familiar brand name doesn’t determine quality. What matters is where the plants come from, how they’re grown and harvested, how the oils are produced, and whether proper testing confirms their identity and purity.
We don’t want to be disconnected from the ingredients we use. We want to keep learning, asking questions, and staying personally involved, because you trust us to make thoughtful choices for your family.
