ChromEssence is a support laboratory for the essential oil and aromatic chemicals industry. We are not producers or re-sellers, and one of our main values is the independence. Nowadays, a 3rd-Party biochemical characterization of natural products is a market differentiation for companies who trade with ecological certificated products. The recent growth of sectors such as scientific aromatherapy and the lack of "botanical transparency" in essential oil market, makes it necessary to closely monitor the traceability and authenticity of plant-based products. We have the state-of-the art in equipment and data processing, and we have the expertise needed to support the companies and independent professionals who are not specialist in this field.
