Halcyon Haze products are made using pharmaceutical and food grade ingredients, over 99% of which are sourced in the UK from audited suppliers. All our products have undergone extensive toxicological testing to ensure they do not contain diacetyl, acetoin or acetyl propionyl (to trace detection levels of 0.01%), or any ingredients classified as carcinogenic, mutagenic or reprotoxic (CMR). Most products in the Halcyon Haze range are also free from ethanol (to trace detection levels). Please contact us for further details, or if you have any queries relating to our products.
All Halcyon Haze products apart from Sergeant Vapour contain a 50/50 mix of high quality vegetable glycerine (VG) and propylene glycol (PG) alongside natural and nature-identical flavourings. Sergeant Vapour is a 70/30 mix. All our products have been tested and approved by accredited UK Trading Standards laboratories and are sold in child-resistant and tamper-evident bottles. For more information and analytical test reports, see our Compliance and Quality page. Halcyon Haze products have been notified across Europe, in 22 member states. The MHRA (UK’s competent authority for the TRPR) has reviewed and passed Halcyon Haze products, changing their status to ‘declared’.
