Quality Assurance

A Word on Product Quality

All SunLeaf products are envisioned and created in-house by our President and Director of Product Development, Teresa Andrys. With years of experience as a professional formulator, Teresa has extensive knowledge around natural plant materials, essential oils, and 'green' product chemistry. 

We believe that ingredient quality matters – after all, a product is really only as good as the materials from which it is made. That's why we use only the finest-quality botanicals and aromatic plant extracts available, and we consistently re-evaluate the raw materials we utilize to formulate our products to ensure that they continue to meet or exceed our rigorous standards for quality and purity.

Essential oils can be extracted using a variety of methods, including some that require the use of toxic petrochemical solvents. At SunLeaf, we exclusively source essential oils extracted using steam, cold-pressing, or supercritical CO2 – all non-toxic methods that result in superior-quality products. Our suppliers are some of the most reputable and responsible in the world, and they are transparent about what does — and doesn’t — make its way into the essential oils they produce.


Independent Analysis. Our quality assurance process extends beyond our careful sourcing of essential oils — we also require, retain and make available a lot-specific certificate of analysis for each essential oil that we purchase verifying its quality, authenticity, and purity. 

This ensures that the aroma that makes it way into our products is composed of safe, unadulterated natural materials, and that the quality of our aromas remains consistent from batch to batch. To view certificates of analysis for our Single-Note Essential Oils, click here.
