Certificates of Analysis

When it comes to ingredient quality, we believe in supply chain transparency. Unfortunately, as essential oils have become more popular and sought-after, there has been a marked increase in the incidence of adulteration, or the intentional alteration, contamination, or dilution of these precious liquids, in order to 'extend' them, or to pass off inferior product for a higher price.

At SunLeaf, we require that our suppliers furnish a Certificate of Analysis for each batch of essential oil that we purchase. This document reflects the results of a wide variety of analytical chemistry techniques in order to demonstrate essential oil quality and purity. We want you to feel confident that our products are 100% pure and safe, so we publish those certificates of analysis here for your review.
