What Are Terpenes? A Complete Guide for Formulators

Terpenes are naturally occurring aromatic compounds found in a vast array of plants, fruits, and herbs. They are responsible for the distinctive scents of lavender, citrus, pine, and cannabis — and they play a far more significant role in wellness formulation than many realise.

From a chemistry standpoint, terpenes are built from repeating five-carbon isoprene units. Monoterpenes (two isoprene units) include familiar molecules like Limonene and Linalool. Sesquiterpenes (three units) include Beta-Caryophyllene, one of the most studied terpenes for its interaction with the endocannabinoid system.

For formulators, terpenes offer a powerful toolkit. They can modulate the sensory profile of a product — its aroma, flavour, and even mouthfeel — while contributing functional properties. Limonene, for instance, is widely used for its uplifting citrus character and studied for its antioxidant properties. Myrcene is associated with relaxation and is a dominant terpene in many indica-leaning cannabis cultivars.

At AOHA Limited, we supply over 130 GMP food-grade terpene profiles to brands across the UK and Europe. Whether you are developing a vape liquid, a functional beverage, a skincare serum, or a nutraceutical, understanding terpenes is the first step to building a differentiated product.

The entourage effect — the theory that terpenes work synergistically with cannabinoids and other plant compounds — has driven significant interest in full-spectrum and broad-spectrum formulations. While research is ongoing, many formulators are already leveraging terpene blends to create more nuanced, effective products.

If you are new to terpene formulation, our team at AOHA is here to help. We offer consultancy services alongside our terpene supply, guiding brands from concept through to compliant, market-ready products.
