Using Terpenes in Vapes and E-Liquids: Formulation Guide

Terpenes have become an essential ingredient in premium vape and e-liquid formulations. They deliver authentic botanical flavour profiles, contribute to the overall sensory experience, and — when sourced correctly — are safe for inhalation at appropriate concentrations.

The key distinction for vape applications is inhalation safety. Not all terpenes are suitable for vaping, and concentration matters enormously. Terpenes that are perfectly safe in food applications may require lower usage rates in inhalable products. Working with a knowledgeable supplier who understands these distinctions is critical.

Commonly used terpenes in vape formulations include Myrcene (earthy, musky, relaxing), Limonene (bright citrus, uplifting), Beta-Caryophyllene (spicy, woody, the only terpene known to interact with CB2 receptors), Linalool (floral, lavender, calming), and Pinene (fresh pine, alertness).

Typical usage rates for terpenes in vape liquids range from 0.5% to 3% by volume, depending on the terpene and the desired intensity. Starting at the lower end and titrating upward is best practice. Exceeding recommended concentrations can result in harsh vapour, throat irritation, or off-notes.

AOHA Limited supplies GMP food-grade terpenes specifically selected for vape applications. Our formulation team can advise on appropriate terpene selection, blending ratios, and carrier compatibility — whether you are working with PG/VG bases or MCT oil.

Regulatory compliance is also a consideration. UK vape regulations under the Tobacco and Related Products Regulations (TRPR) and the upcoming Tobacco and Vapes Bill set requirements around ingredients and safety. Our team stays current with regulatory developments to help clients formulate compliantly.
